Super Sensitive Touch(TM) built on ClearPad (TM) Series 3 enables enhanced touch support on Nokia's first Windows Phone 8 smartphones
SANTA CLARA, California - Synaptics Inc. (NASDAQ: SYNA), a leading developer of human interface solutions, today announced that the new Nokia Lumia 920 and Nokia Lumia 820 will be the first smartphones in the world to use a new advanced multi-touch experience based on the Synaptics ClearPad capacitive touchscreen sensing technology.
Synaptics ClearPad Series 3, the premier mobile touch solution for premium high end smartphones, has raised the bar for high performance touch on the Lumia 920 and Lumia 820 with the introduction of support for gloves and fingernails.
Previously, people were unable to use their smartphone touchscreens with gloved fingers or long fingernails, requiring them to remove their gloves, or awkwardly position their fingers with long nails in order to operate their phones. For the first time ever, ClearPad Series 3 technology instantly optimizes the touch experience by automatically detecting the presence of skin, gloved fingers, or fingernails, giving users a seamless multi-touch experience regardless of input methods.
"With Synaptics' continuous innovation on touch, we are able to pioneer new technologies that improve the smartphone user experience," said Kevin Shields, senior vice president, Smart Devices, Nokia. "Nokia has been a leader in display technology, and we are setting a new standard with Super Sensitive Touch technology on the Nokia Lumia 920 and Nokia Lumia 820." Nokia's flagship Windows Phone 8 device, the Nokia Lumia 920, features an impressive smartphone display based on exclusive technology called Nokia PureMotion HD+. With better than HD resolution, overdrive technology for keeping moving images pixel-perfect and sunlight enhancements for easy viewing even in the brightest sunlight, the 4.5-inch display of the Lumia 920 produces a totally immersive experience. PureMotion displays are super-sensitive with any touch interaction, enabled by the ClearPad Series 3 technology.
"We are excited to participate with Nokia as they unveil their first Windows Phone 8 devices by enabling advanced features such as gloved finger support," said Kevin Barber, senior vice president and general manager of Synaptics Handheld Division. "Synaptics and Nokia have partnered for many years and we're pleased to continue the innovation with the introduction of these new devices."
ClearPad Series 3 offers up to 10 finger full-time tracking and fast refresh rates, with industry leading signal-to-noise-ratio (SNR), delivering high performance to the most demanding smartphones. Synaptics' patented Signal Clarity(TM) technology improves tracking accuracy, finger separation, and environmental and electrical noise robustness for an unmatched user experience. Synaptics' Design Studio(TM)4 (DS4) accelerates the ClearPad development cycle by enabling customers to evaluate and optimize the performance of their touch experience, enabling OEMS to implement their custom ClearPad sensor solution more efficiently.

Qi (wireless power standard):
From Wikipedia, the free encyclopaedia
Qi (the Chinese word for energy flow, pronounced "chee") is a proprietary interface standard developed by the Wireless Power Consortium for wireless electrical power transfer over distances of up to 40 millimetres (1.6 inches). The Qi system comprises a power transmission pad and a compatible receiver in a portable device. To use the system, the mobile device is placed on top of the power transmission pad, which charges it via magnetic induction.
Mobile device manufacturers that are working with the standard include HTC, Huawei, LG Electronics, Motorola Mobility, Nokia, Samsung, and Sony. The Wireless Power Consortium was established in 2008, and is an open-membership cooperation of Asian, European, and American companies in various manufacturing industries. Their aim is to create a global proprietary standard for wireless charging technology.
Features and Specifications
Under the Qi specification, "low power" for wireless transfer means a draw of 0 to 5 W. Systems that fall within the scope of this standard are those that use inductive coupling between two planar coils to transfer power from the power transmitter to the power receiver. The distance between the two coils is typically 5 mm. It is possible to extend that range to at least 40mm. Regulation of the output voltage is provided by a digital control loop where the power receiver communicates with the power transmitter and requests more or less power. Communication is unidirectional from the power receiver to the power transmitter via backscatter modulation. In backscatter modulation, the power-receiver coil is loaded, changing the current draw at the power transmitter. These current changes are monitored and demodulated into the information required for the two devices to work together.
The WPC published the Qi low power specification in August 2009. The Qi specification is available as free public download.In 2011, the Wireless Power Consortium began to extend the Qi specification to medium power. The low-power specification delivers up to 5 watts; the medium-power specification will deliver up to 120 watts.
System Overview
Devices that operate with the Qi standard rely on magnetic induction between planar coils. Two kinds of devices are at use – the Base Stations, which provide wireless power, and Mobile Devices, which consume wireless power. The Base Station contains a power transmitter that comprises a transmitting coil; the Mobile Device contains a power receiver holding a receiving coil. Close spacing of the two coils, as well as shielding on their surfaces, ensure the wireless power transfer is efficient. Shielding also aids to minimize users’ exposure to the magnetic field, meaning it’s safe for consumers.
Base Stations typically have a flat surface—referred to as the Interface Surface—on top of which a user can place one or more Mobile Devices. There are two methods for aligning the transmitting coil (part of the Base Station) and receiving coil (part of the Mobile Device) in order for a power transfer to happen. In the first concept—called guided positioning—a user must actively place the Mobile Device on a certain location of the Base Station's surface. For this purpose, the Mobile Device provides an alignment aid that is appropriate to its size, shape and function. The second concept—referred to as free positioning—does not require the user to put his or her Mobile Device in direct alignment with the transmitting coil. There are several ways to achieve free positioning. In one example a bundle of transmitting coils is used to generate a magnetic field at the location of the receiving coil only. Another example uses mechanical means to move a single transmitting coil underneath the receiving coil. A third example is to use a technique called "Multiple Cooperative Flux Generators."
As shown, a power transmitter includes two main functional units -- a power conversion unit and a communications and control unit. The diagram shows the transmitting coil (array) generating the magnetic field as part of the power conversion unit. The control and communications unit regulates the transferred power to the level that the power receiver requests. The diagram also demonstrates that a Base Station may contain numerous transmitters, allowing for multiple Mobile Devices to be placed on the same Base Station and wirelessly charge until each of its batteries are fully charged. Finally, the system unit in the diagram comprises all other functionality of the Base Station, such as input power provisioning, control of multiple power transmitters, and user interfacing.
A power receiver comprises a power pick-up unit, as well as a communications and control unit. Similar to the power conversion unit of the transmitter, Figure 1-1 illustrates the receiving coil as capturing the magnetic field of the power pick-up unit. A power pick-up unit typically contains a single receiving coil only. Moreover, a Mobile Device typically contains a single power receiver. The communications and control unit regulates the transferred power to the level that is appropriate for the subsystems (e.g., battery) connected to the output of the power receiver. These subsystems represent the main functionality of the Mobile Device.
