Cell phone cameras

Smaller fuel cells (1 kW and lower) may be used as portable power as well as back-up power (uninterruptible power supply) or as battery chargers. Small fuel cells are also being developed as battery replacement which would enable longer operation time for consumer electronics (such as laptop computers, cell phones, cameras, and music players). There is a wide array of possible fuel cell applications in military battery chargers, telecommunications, navigation systems, soldier power, computers, various power tools,... 

Microlenses are used extensively in cell phone cameras (18). 

A charge-coupled device (CCD) is the imaging system at the heart of every digital camera, Web cam, and cell phone camera. CCDs are also found in scanners, fax machines, and many other places where digital images are needed. 

Performance, rather than cost, has been the primary driver for the adoption of COCs into industry. With applications in lenses for laser printers, LCD screens, cell phone cameras, and other high-value products, only a small amount of polymer is required to produce valuable parts. Accordingly, the market can accommodate a relatively high price per pound for these materials. Due to the stringent purity requirements for optical applications, much of the cost associated with COC manufacturing is in contaminant removal and clean room handling. Taken together, the impact of raw material and polymerization costs is relatively small compared to other polymeric materials. 

Perhaps you have just purchased a new electronic device, such as a personal computer, video camera, pager, or cell phone. The advanced circuitry in such devices can malfunction in humid environments. Moisture can reroute and even short circuit electric signals, impairing the operation of your new electronic equipment. Manufacturers recognize that moisture can adversely affect their products and... 

Fuel cells can be used to power a variety of portable devices, from handheld electronics such as cell phones and radios to larger equipment such as portable generators. Other potential applications include laptop computers, personal digital assistants (PDAs), and handheld video cameras—almost any application that has traditionally used batteries. These fuel cells have the potential to last more than three times as long as batteries between refueling. 

Lithium batteries are now used in cell phones, laptop computers, and cameras. 

The importance of these bullet detectors is that a cluster of them might give similar data at a fraction of the cost when compared to a monochromator-based instrument. In fact, as the cost declines for these devices, it could (conceivably) be less expensive to discard older sensors than to recalibrate them. (Disposable instruments Why not We already have disposable cameras and cell phones )... 

Among the many applications of ECPs, perhaps the most successful has been the commercialization of OLEDs in automobile radios, electric shavers, cell phones, and cameras displays (in limited venues) [73]. In the case of OTFTs, those produced from ECPs show certain advantages their softness is beneficial to their low-temperature processability and fine-tuning of their structure-property relationships, and they are inexpensive to produce. However, their morphology and microcrystallinity, and hence other important physico-chemical characteristics, may be difficult to control, as might also be their reproducibility of performance. Clearly, the many ongoing investigations with ECPs will contribute much to the future success of these materials.

Medis Technologies of Israel, has created a disposable auxiliary power unit, the Power Pack, for use on a wide range of electronics including cell phones, PDAs, digital cameras, MP3 players, and other small electronics. The Power Pack has a significantly longer operating time than traditional batteries. For example, when used for a cell phone, the... 

Right, on CNN. Now, if you look at the London bombings (in 2005), that s the Nokia effect. That s on cell phones. The Green Party in Iran, with the death of Neda [Agha-Soltan, in 2009], that was all [reported] by cell phone and cameras. And I think that speaks again to the... 

Lithium ion batteries proved to be very advantageous. Their development was very rapid and their specific characteristics more than doubled in 10-15 years, while their cost decreased fivefold. Their production scale grew at a tremendous rate. Current annual production is several billions of pieces. It was the large-scale production of lithium ion batteries that determined the modem production rate of such devices as cell phones, digital photo and video cameras, notebooks, and wireless power tools. 

While consumer applications such as cell phones, notebook computers, camcorders, and cordless tools will be the obvious mass market application for direct methanol fuel cells at a power level up to 100 W, there should be an earlier market for PEM fuel cells in a niche sub-1 kW market. The t)rpe of device that fits this class includes weather stations, signal units, APUs, gas sensors, and security cameras. Companies involved in this area include Plug Power www.plugpower.com and Ballard Power Systems www.ballard.com." ...
