Pong Research
Pong Research Corporation was a cell phone accessories company that invented the Pong Case, a cell phone case with an embedded antenna that reduces exposure to cell phone radiation. History Pong Research was incorporated in 2011 and in 2014 relocated to Leesburg, Virginia to Encinitas, California. The company was financially backed by Catterton Partners, the leading consumer-focused private equity fund with over $4.5 billion under management. In 2014, the company changed its name to Antenna79, Inc. In 2016 Antenna79 merged with Invisible Gadget Guard, Inc. (a cell phone accessories company specializing in screen protection) to become Penumbra Brands, LLC. Technology The Pong Case antenna technology was created by PhD scientists educated at Harvard, MIT, UCLA and the University of Manchester. Using their knowledge of manipulating radiofrequency (RF) electromagnetic fields, Pong invented a coupling and re-radiating antenna that redistributes cell phone near-field radiation ...

Mobile Phone Accessories
Mobile accessories include any hardware that is not integral to the operation of a mobile smartphone as designed by the manufacturer, and adds utility to the mobile phone. Cases Cases, which are designed to attach to, support, or otherwise hold a smartphone, are popular accessories. Case measures are based on the display inches (e.g. 5 inch display). There are different types: * Pouches and sleeves * Holsters * Shells * Skins * Fitted cases * Bumpers * Flip cases and wallets * Screen protection films * Camera protection films * Drop and shock protection * Leather cases * Cases with integrated kick stands * Battery cases * Cases with protection devices Holsters are commonly used as third-party cases for devices, and/or are made of plastic and without exposed rigid corners. Heavy duty cases are designed to protect from drops and scratches. A standing (or kickstand) case keeps the device standing upright. The collapsible kickstand of some horizontal cases holds the device i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Frequency
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around to around . This is roughly between the upper limit of audio frequencies that humans can hear (though these are not electromagnetic) and the lower limit of infrared frequencies, and also encompasses the microwave range. These are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves, so they are used in radio technology, among other uses. Different sources specify different upper and lower bounds for the frequency range. Electric current Electric currents that oscillate at radio frequencies (RF currents) have special properties not shared by direct current or lower audio frequency alternating current, such as the 50 or 60 Hz current used in electrical power distribution. * Energy from RF currents in conduct ...

Specific Absorption Rate
Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed per unit mass by a human body when exposed to a radio frequency (RF) electromagnetic field. It is defined as the power absorbed per mass of tissue and has units of watts per kilogram (W/kg). SAR is usually averaged either over the whole body, or over a small sample volume (typically 1 g or 10 g of tissue). The value cited is then the maximum level measured in the body part studied over the stated volume or mass. Calculation SAR for electromagnetic energy can be calculated from the electric field within the tissue as :\text = \frac\int_\text \frac \,d\mathbf, where :\sigma is the sample electrical conductivity, :E is the RMS electric field, :\rho is the sample density, :V is the volume of the sample. SAR measures exposure to fields between 100 kHz and 10 GHz (known as radio waves). It is commonly used to measure power absorbed from mobile phones and during MRI scans. The ...

Wired (magazine)
''Wired'' is a bi-monthly American magazine that focuses on how emerging technologies affect culture, the economy, and politics. It is published in both print and Online magazine, online editions by Condé Nast. The magazine has been in publication since its launch in January 1993. Its editorial office is based in San Francisco, California, with its business headquarters located in New York City. ''Wired'' quickly became recognized as the voice of the emerging digital economy and culture and a pace setter in print design and web design. From 1998 until 2006, the magazine and its website, ''Wired.com'', experienced separate ownership before being fully consolidated under Condé Nast in 2006. It has won multiple National Magazine Awards and has been credited with shaping discourse around the digital revolution. The magazine also coined the term Crowdsourcing, ''crowdsourcing'', as well as its annual tradition of handing out Vaporware Awards. ''Wired'' has launched several in ...

ALARP
As low as reasonably practicable (ALARP), or as low as reasonably achievable (ALARA), is a principle in the regulation and management of safety-critical and safety-involved systems. The principle is that the residual risk shall be reduced as far as reasonably practicable. In UK and NZ Health and safety law, it is equivalent to so far as is reasonably practicable (SFAIRP). In the US, ALARA is used in the regulation of radiation risks. For a risk to be ALARP, it must be possible to demonstrate that the cost involved in reducing the risk further would be disproportionate to the benefit gained. Factors Determining that a risk has been reduced to ALARP involves an assessment of the risk and costs involved in taking measures to avoid that risk, and a comparison of the two according to cost–benefit analysis (CBA). In this context, risk is the combination of the frequency (likelihood) and the consequence of a specified hazardous event. Several factors are likely to be considered whe ...

RF Signal
Radio waves (formerly called Hertzian waves) are a type of electromagnetic radiation with the lowest frequencies and the longest wavelengths in the electromagnetic spectrum, typically with frequencies below 300 gigahertz (GHz) and wavelengths greater than , about the diameter of a grain of rice. Radio waves with frequencies above about 1 GHz and wavelengths shorter than 30 centimeters are called microwaves. Like all electromagnetic waves, radio waves in vacuum travel at the speed of light, and in the Earth's atmosphere at a slightly lower speed. Radio waves are generated by charged particles undergoing acceleration, such as time-varying electric currents. Naturally occurring radio waves are emitted by lightning and astronomical objects, and are part of the blackbody radiation emitted by all warm objects. Radio waves are generated artificially by an electronic device called a transmitter, which is connected to an antenna, which radiates the waves. They are received ...

IPhone 3G
The iPhone 3G is a smartphone developed and marketed by Apple Inc. It is the List of iPhone models, second generation of iPhone, successor to the IPhone (1st generation), original iPhone, and was introduced on June 9, 2008, at the WWDC#2008, WWDC 2008 which took place at the Moscone Center in San Francisco. The iPhone 3G is internally similar to its predecessor, but included several new hardware features, such as GPS, 3G data and multi-band, tri-band Universal Mobile Telecommunications System, UMTS/High-Speed Downlink Packet Access, HSDPA. The device was originally loaded with the concurrently launched iPhone OS 2.

University Of California, Los Angeles
The University of California, Los Angeles (UCLA) is a public university, public Land-grant university, land-grant research university in Los Angeles, California, United States. Its academic roots were established in 1881 as a normal school then known as the southern branch of the California State Normal School which later evolved into San Jose State University, San José State University. The branch was transferred to the University of California to become the Southern Branch of the University of California in 1919, making it the second-oldest of the ten-campus University of California system after the University of California, Berkeley. UCLA offers 337 undergraduate and graduate degree programs in a range of disciplines, enrolling about 31,600 undergraduate and 14,300 graduate and professional students annually. It received 174,914 undergraduate applications for Fall 2022, including transfers, the most of any Higher education in the United States, university in the United Stat ...
