![]() They are strong enough to withstand the impact of bees running into things. In addition to resilin, bee wings are made up of membranes, bee blood ( hemolymph), nerves, hairs, and breathing tubes.įor such a small part of the bee, the wings hold more than what the naked eye can see. This gives the wings flexibility so that they don’t break upon impact. Resilin can be likened to the firm plastic film. Resilin is an elastic protein that makes up the joints of bee wings. The top and bottom layers encase the middle one protecting the hemolymph. Bottom layer: The same membrane as the top layer.Middle layer: This is where the hemolymph lies, which are the nerves and blood vessels.Top layer: A thin, sheer membrane that is like a human’s fingernail cuticle.While bee wings themselves are sturdy, the muscles that keep them moving are one of the strongest parts of bees. This motion can be likened to “surfing” into safety. Bees use their wings to create waves so that they can propel themselves forward. Hydrofoil: Bees getting stuck in water is a common sight, but they aren’t completely helpless when it comes to drowning.Nest ventilation: The fast beating of bee wings circulates airflow within the hive, creating a more comfortable environment for the bees.Queen brooding: The queen bee and her subjects use their temperature control abilities to heat up the hive and the queen so that her eggs can keep warm.They can also regulate their body temperature when they are too hot. This can be compared to humans shivering to get warm. Temperature control: Honeybee flight muscles must be at least 86 degrees Fahrenheit to take flight.These moves translate to other bees how close food supply is. They beat their wings while shaking their bodies and waggling. Communicating: Bee dancing is a form of communication.Then, bees will beat their wings to further dry the honey. One of the last steps of forming honey is placing it in a cell. Bees do this by using their digestive system to absorb nectar moisture and by flying around with nectar in their mouths. Dehydrating honey: A large part of transforming nectar into honey is dehydrating.This is the source of bees’ telltale buzzing sound. Flying: Bee wings beat 230 times per second.For honeybees, they’re also essential tools to maintaining the health of hives and honey. The forewings are larger than the hindwings. In reality, bees simply create mini-hurricanes wherever they go, which is a lot easier to get your head around.Bees have four wings: two forewings and two hindwings. So the next time someone tells you a bee shouldn't be able to fly, you should inform them that this is merely a myth perpetuated by popular culture. The eyes of these mini-hurricanes have a lower pressure than the air outside, which lifts the bees upwards. Rather than being like a propeller, the angle to the wing creates vortices in the air like small hurricanes. Insects sweep their wings in a partial spin. This was previously a big misconception about the way insects fly, and could have originally been what tripped Magnan up in the first place.Īn aeroplane's wing forces air down, which pushes the plane upwards. But like honeybees, they are inefficient."Īnother study from 2005, by biology professor Michael Dickinson from the University of Washington, also concluded that bees flap their wings back and forth, not up and down. "Racing cars can reach higher revolutions per minute but enable the driver to go faster in higher gear. "They work like racing cars," one of the authors of the study, Douglas Altshuler, told Live Science. In reality, they simply fly in a completely different way. A regular Boeing 747 plane can also take off at roughly 184 mph, whereas bees do not reach anywhere near that speed.ĭue to low speeds, and the high amount of drag when bees flap their wings, it might look like they shouldn't be able to fly. But the small wings of a bee compared to its relatively fat body are not. The wingspan of a plane is large enough to satisfy the lift equations for flight, so they don't need to flap. ![]() Drag is reduced thanks to a streamlined shape, and lightweight materials. Planes use wings for lift and engines for thrust. The lift force must balance its weight, and thrust must exceed its drag, to make flying possible. ![]() And if bees flew like aeroplanes, he would be correct.Īeroplanes can fly because of a careful balance of four physical forces: lift, drag, weight, and thrust. The myth dates back to the 1930s, when the French entomologist August Magnan noted that a bee's flight should be impossible, because of the haphazard way their wings flapped around.

![]() The XP 510's mic is also detachable to prevent dust buildup, and has a slick aluminum cover that prevents the mic's felt tip from falling off. The detachable mic on the XP510 has a quality micro-gooseneck boom that flexes easily. Other headsets such as the Razer Chimaera have detachable mics that are made of poorly-constructed rubber material and couldn't bend properly for good voice delivery in chat sessions. I've used some of the better Tritton AX Pro models with rotating earcups, but I shouldn't like to suffer the stickiness and heat of pleather ear cushions again during marathon gaming sessions. This feature is very useful for when you need to rest your headset on your shoulders! The ear cushions act like clamps and hold the headset steady when you need to take a break from your gaming session. One particularly excellent innovation is that the XP510 has 180 degree fully-rotating ear cups. Overall, I like the sturdy design of the headset. The Bluetooth functionality on both the Xbox 360 and PS3 functioned flawlessly, and pairing both the controller and a second device was easy (see below). Theoretically, you could game on a Saturday from 10:00 AM to 1:00 AM the next day and just recharge them overnight. After the initial charge, my headset lasted a full 15 hours. The rechargeable batteries are LiPo (lithium polymer), an advanced long-lasting battery type. The headset's batteries have a good lifespan. I found that the headset offered a combination of features that I was specifically on the hunt for. Setting up the pairing is a matter of following the prompts on the XMB under PS3 Settings/Accessory Settings.īack view of XP510 earcups rotated 90 degrees on base unit. The PS3 setup process involves enabling the console to "find" your PS3 controller. Just insert the XBA Bluetooth Chat Adapter and easily pair it with the base unit. You can connect your Xbox controller wirelessly without the bothersome controller cord (aka the Xbox Talkback Cable) that dangles down to your controller. The XP510, when it comes to wireless connections, offers a bonus. Dedicated gamers who still have interference problems might purchase a dual-band router and port their gaming permanently to the 5 GHz band. With today's wireless device-populated wifi channels, it can be challenging to find wifi solace. You can easily verify your wifi settings and set the channel on your router for relatively interference-free broadcasting with this tool. Many people experience interference from household electronic devices (and nearby, overlapping wireless networks) on the 2.4 GHz band. It automatically scans for the 2.4 GHz or 5 GHz band, selecting the band with an optimal wireless connection and the least interference. The Turtle Beach digital RF wireless transmitter is dual-band wifi-capable. ![]() ![]() The way this technology works is that it maximizes network workloads. If the pre-pair sequence was lost somehow you can still connect by (starting with headset powered off) repeating the standard sequence of base station-to-headset pairing steps. The headset and transmitter are handily pre-paired out of the box. Note that connecting to an original Xbox 360 model will require an Xbox 360 HDMI Audio Adapter Cable. You're done when the pleasant Siri-like voice says, “Powering on”. Press and hold the power button until the LED turns solid. Insert the mic boom and power on the headset. Just connect your optical cable to the Digital In port and power cable to your game console of choice. Setting up headsets and pairing them to base stations can be a needlessly time-consuming and frustrating experience, but setup for the XP510 was quick and without incident. ![]() ![]() The resistor values are not critical, any resistor value between 4k7 and 22K can be used for the two resistors. The freewheeling diode associated with the relay safeguards the transistor from back EMF voltage spikes generated by the relay coil. When it's a PNP transistor such as a BC557, the base terminal of the transistor is coupled with the collector terminal of the optocoupler's internal transistor, the emitter is connected with the positive line and the collector pin is configured with the relay. As shown in the following circuit diagrams, the relay driver may consist a NPN transistor or a PNP transistor.Īn external transistor is recommended in a situation where the relay coil resistance is low, below 300 ohms and the relay requires a higher amount of current above 50 mA.Īs can be seen diagram below, a PNP relay driver is connected with the optocoupler. The following concepts show how a relay driver can be configured with an optocoupler using transistors. This is because, most optocouplers cannot handle more than 50 mA current as the load current, therefore the relay coil must have a relatively high resistance so that it does not pass more than 30 or 40 mA current. So if you want to use the above configuration and connect the relay directly with the optocoupler, then you have to first measure the coil resistance of the relay and make sure it is higher than 300 ohm. Remember, although the above connection diagram looks simple and easy, you must ensure that the relay coil resistance is not below 300 ohms, otherwise the optocoupler may heat up and get destroyed. In the following circuit diagram we can see how a relay can be connected directly connected with the collector of the optocoupler's internal transistor. Connecting Relay Directly with an Optocoupler The photo-transistor output is normally used for driving the preceding isolated stage, for example a relay driver stage. ![]() The above action illuminates the internal LED whose light is detected by the photo-transistor causing it to conduct across its relevant pin outs. The idea of operating a relay with an optocoupler is simple, it's all about providing an input DC from the source which needs to be isolated to the LED pin outs via a limiting resistor (as we normally do with usual LEDs) and to switch the photo transistor in response to the applied input triggers. The LED is terminated over a couple of pin outs, while the three terminals of the photo-transistor is terminated over the other three assigned pin outs. An opto-coupler is a device which encapsules an LED and a photo-transistor inside a hermetically sealed, water proof, light proof package in the form of an 8 pin IC (resembling a 555 IC). ![]() I take a lot of time and care in choosing my fabrics, the best quality and beautiful prints.

For example, a 75W90 transmission oil doesn't have a higher viscosity than a 15W40. If you are interested, you can see more information regarding SAE specifications here.īut be careful: transmission oils have a different SAE numbers. Here you can see the recommended oil for each ambient temperature: You should be aware of climate changes in order to keep your engine fully functional. The number before the W represents the oil viscosity at lower temperatures, while the second number (after the W) indicates the viscosity at operating temperatures.įor example, this means that 5W30 engine oil has less viscosity at lower and higher temperatures when compared to 10W40. The SAE (Society of Automotive Engineers) established a numerical code to represent the viscosity of oil at both hot and cold temperatures. Some synthetic oils are able to achieve this variation without additives. To be able to change the viscosity index, conventional oils incorporate additives, usually plastic polymers. Thus, the viscosity index measures the ability of an engine oil to resist becoming thinner at high temperatures. The viscosity changes with temperature to ensure protection and operability under all circumstances. A higher viscosity implies a slower flow and a thicker fluid. ![]() Viscosity is simply the resistance of a fluid to flow. Find out more about the latest technologies being used to detect hydrogen contaminants in ‘Combination of OFCEAS Spectroscopy and Low Pressure sampling, for Impurities Measurement in Hydrogen Production and Storage.After a brief review of the use of engine oil, we will now move on to one of the most important concepts: oil viscosity index. The hydrogen market is also concerned with impurities that can contaminate gas and damage fuel cells. Even minor changes can impact performance and increase the risk of unplanned downtime and in a worst case scenario, critical failure.Ĭontaminants such as H20 and particulate matter don’t just compromise the efficacy of lubricants. Monitoring viscosity is one of the most importance elements of any lubricant analysis strategy. However, a variety of factors can affect viscosity and compromise a lubricant’s ability to achieve goals like reducing friction and preventing wear. Viscosity is generally calculated using a clean and high quality sample, in stable operating conditions at a temperature of 40☌. ASTM D2270 is one of the most widely used methods used to calculate viscosity index. At 100☌ both benchmark oils should have the same viscosity as the lubricant being tested. A number is assigned by comparing the kinematic viscosity of the lubricant at 40☌ with the kinematic viscosity of two benchmark oils, one with a VI of 100 and the other with a VI of 0. Viscosity index (VI) is used to measure how dependent on temperature the kinematic viscosity of a lubricant is. Dynamic viscosity measures the force needed for the lubricant to achieve a certain flow rate. Kinematic viscosity describes the rate at which a lubricant is flowing when exposed to a certain level of force. When describing viscosity, two parameters are used. They’re generally used for smaller, faster moving components. In comparison, low viscosity lubricants are thin and fast-flowing. High viscosity lubricants are thicker and more resistant to flow, making them suitable for heavy-duty applications. As a result, viscosity is one of the most important physical properties of lubricants considered when developing mechanical maintenance strategies. Viscosity plays an important role in determining the thickness of the protective film created by the lubricant, as well as factors like load capacity and ability to reduce friction. What is viscosity?Īlso known as internal friction, viscosity describes how resistant a lubricant is to flow. Internal resistance to flow determines how a lubricant will behave when in use, if it can achieve specific goals and ultimately, if it’s suitable for the application.īelow, we take a closer look at the importance of viscosity and why it’s one of the top physical properties of lubricants considered by operators. Viscosity is one of the most important physical properties of lubricants to consider when choosing a product. From ultra-light oils to heavy-duty greases, lubricants come in an array of forms.

After joining Google in 2011 to work on products that "would change how people used their TVs", Bakar pitched the idea for the Chromecast. Bakar found the whole process inefficient and wanted to build a phone-based interface that would allow video to play on a large display through a small hardware device. She took these steps because she found television interfaces difficult to use to search for content. Using her laptop, she would search for a film to watch on a streaming service and add it to her queue, before closing her laptop and using a gaming device to play the film on a television. His inspiration for the product came around 2008 after noticing the film-viewing tendencies of his wife Carla Hindie. From Chromecast's launch to May 2015, it handled more than 1.5 billion stream requests.Īccording to Google, the Chromecast was originally conceived by engineer Majd Bakar. Chromecast was the best-selling streaming device in the United States in 2014, according to NPD Group, and over 30 million units in the product line have sold globally. According to Google, over 20,000 Google Cast–ready apps were available as of May 2015. The Google Cast SDK was released on February 3, 2014, allowing third parties to modify their software to work with Chromecast and other Cast receivers. The latest models, called Chromecast with Google TV, were the first in the product line to feature an interactive user interface and remote control a 4K model was released in September 2020, followed by a 1080p model in September 2022.Ĭritics praised the Chromecast's simplicity and potential for future app support. A third generation of the HD video Chromecast was released in October 2018. A model called Chromecast Ultra that supports 4K resolution and high dynamic range was released in November 2016. The second-generation Chromecast and an audio-only model called Chromecast Audio were released in September 2015. The first-generation Chromecast, a video streaming device, was announced on July 24, 2013, and made available for purchase on the same day in the United States for US$35 (equivalent to $43.97 in 2022). Content can be mirrored to video models from the Google Chrome web browser on a personal computer or from the screen of some Android devices. The user can control playback with a mobile device or personal computer through mobile and web apps that support the Google Cast protocol, or by issuing commands via Google Assistant later models introduced an interactive user interface and remote control. The devices, designed as small dongles, can play Internet- streamed audio-visual content on a high-definition television or home audio system.

The first part is just like a CAPTCHA, where you’ll need to drag a puzzle piece to the other side of the screen. This is where you can complete the security verification process. Next, you’ll need to verify your WeChat account. How Do I Sign Up for WeChat Without a Friend?.Let’s talk about how you can create WeChat account on a device you’ve never used it on before. Not only that, you’ll also need an existing WeChat user to verify your account. When you install the WeChat app on your device, you’ll first need to sign up with a valid mobile phone number. You should note that while WeChat can help you connect with your friends, it lacks end-to-end encryption and collects data.However, you can also try contacting WeChat support to see if they’re willing to help. In most cases, you’ll need to ask a WeChat user to verify your account.Signing up for WeChat is different from other apps because it involves an extensive verification process.However, if you’ve decided to use it, you’ll first need a WeChat account, and creating one can be quite a process.
