In the 1870s, British physicist William Crookes and others were able to evacuate rarefied tubes to a pressure below 10 −6 atm. In 1838, Michael Faraday passed a current through a rarefied air-filled glass tube and noticed a strange light arc with its beginning at the cathode (negative electrode) and its end almost at the anode (positive electrode). After the electrons reach the anode, they travel through the anode wire to the power supply and back to the cathode, so cathode rays carry electric current through the tube. Researchers noticed that objects placed in the tube in front of the cathode could cast a shadow on the glowing wall, and realized that something must be traveling in straight lines from the cathode. The voltage applied between the electrodes accelerates these low mass particles to high velocities.Ĭathode rays are invisible, but their presence was first detected in early vacuum tubes when they struck the glass wall of the tube, exciting the atoms of the glass and causing them to emit light-a glow called fluorescence. They travel in straight lines through the empty tube. Since the electrons have a negative charge, they are repelled by the cathode and attracted to the anode. The increased random heat motion of the filament atoms knocks electrons out of the atoms at the surface of the filament and into the evacuated space of the tube. Modern vacuum tubes use thermionic emission, in which the cathode is made of a thin wire filament that is heated by a separate electric current passing through it. The electric field accelerated the ions and the ions released electrons from the cathode when they collided with the cathode. The early cold cathode vacuum tubes, called Crookes tubes, used a high electrical potential between the anode and the cathode to ionize the residual gas in the tube. To release electrons into the tube, they must first be detached from the atoms of the cathode. The image in a classic television set is created by focused beam of electrons deflected by electric or magnetic fields in cathode ray tubes (CRTs).Ĭathode rays are so named because they are emitted by the negative electrode, or cathode, in a vacuum tube. Electrons were first discovered as the constituents of cathode rays. If an evacuated glass tube is equipped with two electrodes and a voltage is applied, the glass opposite the negative electrode is observed to glow from electrons emitted from the cathode. crookes tube: An early experimental electrical discharge tube, invented by English physicist William Crookes and others around 1869-1875, in which cathode rays, streams of electrons, were discoveredĬathode rays (also called electron beams or an e-beams) are streams of electrons observed in vacuum tubes.

Motion Detection vs Continuous Recording - Two common video recording types are motion detection or motion activated recording, and continuous recording. Viewing angles can range from 65 degrees all the way up to 130 degrees, depending on the camera. The wider the viewing angle, the more the camera lens will be able to see. Viewing Angle - A nanny cam’s viewing angle is how wide the camera is. When night vision is enabled, the video switches from full color to black and white. These night vision sensors are invisible to the human eye, but are visible to the camera lens, so it can see even when the lights are low or completely out. Night Vision Nanny Cameras - Night vision hidden cameras and nanny cams feature a special IR (“infrared”) sensor that allows the camera to see in the dark. For WiFi streaming nanny cameras, frames per second can vary between 15 and 30, depending on the camera. For non-WiFi cameras, 30 frames per second is usually standard. For example, TV shows are generally in 30 frames per second. The more frames per second, the smoother the video. Most cameras now feature either 720P or 1080P high definition video.įrames Per Second (FPS) – Frames per second, or “FPS” for short, refers to the number of video frames per second. Over the years video quality for nanny cameras has improved significantly. Video Resolution – Video resolution refers to the quality of the camera. Some cameras only take up to a 32GB card, while some can take up to 128GB or 256GB memory card. Different camera models can have different size memory card specifications. Micro SD Memory Card – A micro SD card is a type of memory card used by many nanny cameras to store recorded videos. Anyone who wants to protect their home or business with covert video surveillance.Businesses that want to increase security and protect against theft and vandalism.Parents who want to monitor what their children are doing or having over when they aren't around.Homeowners looking to protect their homes from break-ins or robberies.Parents who want to make sure their babysitter or nanny takes good care of their children.The most common wireless nanny camera is the internet remote view hidden cameras, which allow the nanny cam video stream to be broadcast to the owner over the internet, even to an iPhone or Android device. Other nanny cameras are wireless, which allows the video to be streamed to another location where it can be viewed live. Some nanny cameras for home are self-recording, which means that the camera is also a video recorder that saves the video internally, or to a memory card. In addition to different "form factors" or styles of nanny cameras, there are also several different ways that nanny cams function. If you're looking for a good place to start looking, check out our Top 7 Spy Nanny Cams for 2023. Some are mini spy cameras that are as small as a keychain, while other are built into common items such as clocks, smoke detectors, picture frames, teddy bears, DVD players, or fans. Nanny Cameras for home have become popular in recent years, in part due to media coverage that has shown how some babysitters have mistreated the children they've been entrusted to care for. This led to my co-editing two Special Issues for the Journal of Composite Materials. “The most notable accomplishment was the benchmarking exercise during which we evaluated nine emerging analysis methods being developed around the country. “I defined the strategy and led the tactical development of progressive damage analysis for composite structures for the Aerospace Systems Directorate,” said Clay. Clay led several technological advancements during his decades-long career with the Air Force. Since 2012, Clay has served as a research engineer, branch technical advisor and chief engineer for AFRL’s Structures Technology Branch. In 2009, he served as a research engineer, acting branch chief and tech advisor in AFRL’s Analytical Structural Mechanics Branch. By 2007, Clay had moved on to become the Assistant to the Chief Scientist at AFRL, where he worked under Dr. After furthering his education, he spent six years as a research engineer in AFRL’s Advanced Structural Concepts Branch. He went on to earn a Master’s and Doctorate degree in Engineering Mechanics. Successful engineers in AFRL are the ones with an entrepreneurial spirit.”Ĭlay’s career began in 1993 when he was accepted into the Palace Knight Program by Wright Labs. Following their advice to step out of my comfort zone and try new things is likely what led to this recognition. “There have been so many people throughout my career that have mentored me along the way. “Working for AFRL provides countless opportunities to excel,” said Clay. Stephen Clay, a principal aerospace engineer with the Air Force Research Laboratory’s Aerospace Systems Directorate, was named an American Society of Mechanical Engineers (ASME) Fellow, Apat Wright-Patterson Air Force Base, Ohio.Ĭlay has worked for AFRL for 27 years, where he has served as a research engineer on a variety of AFRL programs and projects. WRIGHT-PATTERSON AIR FORCE BASE, Ohio (AFRL) – Dr. Unfortunately, this flavor has a lot to live up to. We’re really starting to head in the direction of creamy ice cream with Chocolate. The texture for some was less than desirable, but I encourage you to find and try this flavor. The cinnamon ice cream base reminded us of the holidays and the oat bits add a fun texture, convincing us of the flavor we know and love. Oatmeal Cookie, a flavor that will always be second best compared to chocolate chip – amiright? However, this ice cream is spot on. Added bonus, there are SPRINKLES mixed in! The only complaint with this flavor was that it needed more sprinkles, duh. How FUN is this flavor?! Birthday Cake tastes EXACTLY like birthday cake, and leaves a less powdery texture than Lemon Cake. That being said, the strawberry flavor was super fresh and tasted like strawberries and cream. We’re still not sure if this was an error, or if every pint is like this. First of all, the pint we tried was very icy, almost like a granita, which some people loved and others loathed. Strawberry received some of the most conflicting results of the entire flavor line up. Had the almonds been less overwhelming, I think this could have made the top 10. However, we were all in agreement that there was too much almond extract in the mix, creating a fake taste, similar to amaretto. Now they’re starting to resemble ice cream! The texture of Chocolate Almond Crunch was much more creamy. We were hoping for a bright citrus zing, but left with a bitter, powdery confusion. Owing to the protein powder, I guess, Lemon Cake was texturally unappealing for me and my taste testers. The texture of this flavor literally felt like cake. We all had high hopes for this American classic, but the protein powder texture left everyone feeling less than fresh. Looking for that “just brushed feeling?” Well then Mint Chip is your flavor! This “fuzzy” ice cream resembles the feeling of when the dentist grinds toothpaste into your teeth that tastes minty, but also a little too sweet. I’d love to see some marshmallow swirl or graham cracker crumble in this, but for now I’ll skip it. Some described this flavor as “fake,” and “ugh, no.” Seems fitting. If it had been called waffles and syrup, then we’ve got a winner! This flavor is lacking the marshmallow, the graham, AND the chocolate. What in God’s name is this?! The name is VERY deceiving in this flavor. Don’t get me wrong, every single pint was finished, but there were a few that were left in the way back of the freezer until my desperation got the best of me. Sounds tempting, right? Well we tried every flavor and while some certainly live up to the hype, others should probably not be on the top of your list. We know it sounds too good to be true, so don’t just take our word for it – dig in and see for yourself just how good healthy ice cream can be!” While Halo Top is low-calorie, high-protein, and low-sugar, we use only the best, all-natural ingredients to craft our ice cream so that it tastes just like regular ice cream. The brand boasts, “Healthy ice cream, that actually tastes like ice cream. You can literally eat an entire pint for less than 250 calories! That is CRAZY TALK, people! If you’re unfamiliar, Halo Top is a low calorie, high protein, low sugar ice cream that is taking the nation by storm. Where to Buy: Arctic Zero can be purchased online or at grocery chains nationwide like Whole Foods and Giant.Let’s play a game, shall we? It’s called e at all the flavors of Halo Top and rank them.* If you want, you can play along by downloading my homemade score sheet here. None of their products have sketchy sugar alcohols either-seriously, they're one of the only ones. Yet, eating spoonfuls of the vanilla bean pint of Arctic Zero was like eating a cloud, and I didn't even feel the need to try the other pints I got.Īrctic Zero also makes lactose-free options, which range from 150-300 calories a pint. I don't even like flavors without chunks usually-I would never order plain vanilla at a scoop shop. The science behind it isn't super clear, but something about the whipped texture works on this kind of ice cream? Arctic Zero manages to keep the ice cream flavor in their scoops while still slicing calories (I'm talking 280 calories a pint) by making their ice cream unbelievably fluffy. Every time I think I have the healthy ice cream market understood, something new pops up. I just got the chance to try Arctic Zero's new and improved pints for myself, and I am elated. |
