While the experts at Car and Driver note that this is not the backup camera for you if you need solid images at night, it might make sense if you have a Garmin display or are okay with shelling out the cash for one. When they blocked the stray light, they did find the image quality improved, however. While the sensor stands up both day and night, Car and Driver found that the image quality dropped dramatically at night, noting flares from any light behind the camera. Despite the wireless connection, they found there was almost no lag between the camera and the display. They found that in daylight conditions the view was almost 180 degrees, meaning that everything in the plane of the backup camera was visible. This tiny camera is wireless between the camera and the display when it's hardwired into a 12-volt power source, though the display does have to be one of Garmin's compatible units, which are sold separately (for Car and Driver's test, they used the DriveSmart 65 GPS). Garmin might be known for their GPS systems circa a time before map applications on our phones, but they also make some pretty sweet backup cameras. If you're sporting an older RV, you might even just have to stick someone outside the vehicle to give you the all clear. If you're driving anything wide or long, like a motorhome or anything on a hitch, you know the pain that is attempting to back up with all that extra bulk. Car and Driver did note that physical installation is straight forward once you find the correct app (there's one for Android and one for iOS), though they found the instructions confusing. A bit clunky for sure, but it's better than running your truck into the fence because you can't see over whatever you've got loaded in the bed. You do pay for the ease of wireless set up though: Every time you want to use the camera, you have to attach the camera and then connect it to your phone's hotspot. The wide-angle lens did give the testers at Car and Driver a comprehensive view of the backup area, even more so when they mounted it higher on the vehicle. The feed uses a local Wi-Fi connection to display the backup image on your smartphone through the camera's phone app. It's battery-powered and rechargeable via USB-C cable. ![]() Car and Driver says it's basically a use-as-needed camera that's magnetically attached to the back of your vehicle (or anything you're towing). When you're looking for a system with not a single wire hanging around, this is the one for you. ![]() Try not to worry about wiring the car front-to-back either the 20-foot cord is more than enough to hide it out of sight. You do have to retrofit the display over your existing mirror, but Car and Driver found that this system is levels above everything they tested and a great overall value. ![]() The mirror display is powered via a 12-volt plug that's the cigarette lighter, which also charges the internal super capacitor so you can grab photos even when your car is off too. The camera is hardwired into your car's fuse panel, and the video is sent over a cable that ends into a mini-jack that plugs into the overhead mirror display. Video feed comes from either the 1080p rearview camera or the 4k dashcam built into the mirror attachment.Ĭar and Driver found set up to be pretty straightforward, though it does require running a cable though your vehicle. When it's non-active, it's a perfectly fine rearview mirror, but when you turn it on and put your car in reverse, it turns into a high-definition rear- and front-facing camera. Instead of your typical video feed on your dash, this backup camera actually attaches over your rearview mirror. It's packed with features: A huge 12-inch display that doubles as a mirror, a dashcam built into the display so you can record what's going on in front of you and (most importantly) a high-quality camera with a solid performance, day or night. The Wolfbox G840S is Car and Driver's top pick for backup cameras, and we wholeheartedly agree. ![]() It has a sidebar, which is usable for current information.

Active duty Soldiers can apply for the career skills program when retiring or separating from the Army when they are looking to get into civilian employment. ![]() While most of the cases are based off monetary need, in some instances funds are available for special categories. Spouses and children may be eligible for educational scholarships toward a bachelor’s degree, re-licensing, or recertification. Winesberry cited some of the least known cases in which financial assistance could be applied for including situations involving vehicle repair, utility bills, or PCS pet transportation. “There are very few programs like this one that can solve a problem right away.” “Soldiers can come in with an issue and leave with funds that can solve that issue,” said Clint Strutt, USAG Benelux division chief of Army Community Service. Categories can expand and adapt year by year and include basic living expenses, medical needs, privately owned vehicle issues, unforeseen emergencies involving travel or funerals, permanent change of station (PCS) expenses, COVID-19 challenges, and additional family support. There are more than 70 offices worldwide that evaluate the allocation of funds to Soldiers based off 30 categories of assistance. “My job is to get to a solution to process the type of assistance that may be required.”ĪER has been helping Soldiers for over 80 years-since World War II when it was first established. I don’t need to know,” said Winesberry, stating that money management classes are available, if the Soldier desires to learn more about habits that foster financial stability. Their command doesn’t even need to know-it’s just a conversation between them and me.”Īdditionally, there is no credit check needed to qualify-only a leave and earnings statement. “Soldiers may be concerned about involving the Army in their financial matters-they are embarrassed. Winesberry acknowledged that Soldiers sometimes feel hesitant to ask for monetary aid because of a perceived stigma. “We are all just humans trying to do our best to navigate challenges and seek the support that’s needed when the time comes.” “AER is all about the human experience and the things that can come up out of your control,” said Maija Winesberry, USAG Benelux financial readiness program manager and AER officer. Army Emergency Relief (AER) recognizes these difficult times and is here to help by supplying funds in the form of grants, scholarships, and zero-interest loans to Soldiers and family members for exactly these situations. ![]() BRUNSSUM, Netherlands – When life takes an unexpected turn and money runs short, some may feel there is nowhere to turn in their time of need. But the true key to achieving that lit-from-within glow is its Airbrush Concealer that evens everything out and eliminates any blemishes or Blotchiness. It’s Ambient Lighting Foundation and recently launched Ambient Lighting powder palette (for fall I go with the six-Pan Tiger option for its warmer tones). "For a light, yet illuminating and flawless, date-night look I turn to Hourglass. As a last tip, Luna says, “When concealing around the face you may even want to opt for a cream concealer, while a liquid texture can work better under the eyes.” Or, go with a full-coverage concealer if hiding spots is your priority. “What you should look for depends on your skin type, concerns, and the look you’re going for.”įor example, if your under-eyes are dry, Luna says to make sure your concealer is a hydrating formula. “Brands do a great job of really laying out what to expect from their formulas,” pro makeup artist Ehlie Luna tells Marie Claire. Of course, your definition of the “best” concealer will depend on your beauty needs.

Other research groups have already achieved promising results with both of these elements, and chromium has also been incorporated into luminescent materials in the past. A potential application could be in the production of active pharmaceutical ingredients.įor a long time, the search for sustainable and cost-effective materials without noble metals focused primarily on iron and copper. This paves the way for photochemical reactions that are otherwise difficult to initiate. The disadvantage of the new materials is that chromium requires a more complex framework than noble metals – and further research will therefore be needed in the future.Įncased in its rigid organic framework, chromium proves to be much more reactive than noble metals when exposed to light. This tailor-made environment helps to minimize energy losses due to undesired molecular vibrations and to optimize the luminescent and catalytic properties. The team designed this organic framework to be particularly stiff, so that the chromium atoms are well packaged. To make the chromium atoms glow and enable them to convert energy, the researchers built them into an organic molecular framework consisting of carbon, nitrogen, and hydrogen. “Here, there’s also the potential to use our new materials in artificial photosynthesis to produce solar fuels,” explained Wenger. ![]() If the new chromium compounds are irradiated with a red lamp, the energy from the light can be stored in molecules which can then serve as a power source. Plants use this process to convert CO2 using sunlight energy into energy-rich glucose and other substances that serve as fuel for biological processes. The new materials are also proving to be efficient catalysts for photochemical reactions, including processes that are triggered by exposure to light, such as photosynthesis. ![]() Click the press release link for a larger image. Image Credit: University of Basel, artistic rendition by Jo Richers. State-of-the-art chromium compounds act as luminescent materials and catalysts. Relative to osmium, however, chromium is about 20,000 times more abundant in the earth’s crust – and much cheaper. Writing in Nature Chemistry, the team reports that the luminescent properties of the new chromium materials are nearly as good as some of the osmium compounds used so far. Researchers led by Professor Oliver Wenger from the Department of Chemistry at the University of Basel have developed chromium compounds that can replace the noble metals osmium and ruthenium – two elements that are almost as rare as gold or platinum – in luminescent materials and catalysts. Soon, however, the element may also be found in the screens of ubiquitous mobile phones or used to convert solar energy. We’re familiar with the chromium material from everyday applications such as chromium steel in the kitchen or chrome-plated motorcycles. Expensive noble metals often play a vital role in illuminating screens or converting solar energy into fuels. In terms of their properties, the new materials are very similar to those used in the past. University of Basel chemists have succeeded in replacing the rare elements osmium and ruthenium with a significantly cheaper metal. |
