A capacitive touch sensor has a clear top plastic film and graphics or other designs disposed on its reverse side. Only the bare plastic substrate is exposed to the environment and user wear. Non-conductive color inks are used in printing the graphics so that any printed capacitive sensors in contact behind will not be short circuited or desensitized. A silk-screened base color layer with a print-free margin left all around its edges allows a later application of adhesive to grip a more durable surface underneath. Capacitive touch sensors are deposited on a bottom plastic film with silvered conductive inks. The printed capacitive sensors on film are fastened with a silk-screen applied liquid water-based adhesive and face the graphics printed side of the first plastic film. A final overcoat of adhesive is applied to the bare backside of the bottom plastic film for final assembly to a frame or chassis.

A method for designing a time-sliced and multi-threaded architecture comprises the steps of conducting a thorough analysis of a range of applications and building a specific processor to accommodate the range of applications. In one embodiment, the thorough analysis includes extracting real time aspects from each application, determining optimal granularity in the architecture based on the real time aspects of each application, and adjusting the optimal granularity based on acceptable context switching overhead.

Method and apparatus for time-sliced and multi-threaded data processing in a communication system

A method for processing data in a spread spectrum system, including decimating a data rate of received spread spectrum data by a decimation factor to a decimated rate; storing the received spread spectrum data into a memory at the decimated rate; interpolating the decimated rate by an interpolation factor to an interpolated rate; and reading the received spread spectrum data from the memory at the interpolated rate.

Method for processing data in a spread spectrum system

An architecture and method for dynamic resource allocation and scheduling in a communication device is disclosed herein. The method of controlling hardware resources in a communication device having a processor, a computer readable memory, and at least one hardware resource coupled to each other includes several steps. The first step locates a memory address in the computer readable memory that is associated with a first hardware resource. In the next step, control information associated with the first memory address is transmitted to the first hardware resource for it to be operated. In the last step, a pointer associated with the first address that locates a subsequent address for a subsequent hardware resource, is read.

Method and apparatus for software-based allocation and scheduling of hardware resources in a wireless communication device

A reconfigurable channel CODEC (encoder and decoder) processor for a wireless communication system is disclosed. A high degree of user programmability and reconfigurability is provided by the channel CODEC processor. In particular, the reconfigurable channel CODEC processor includes processor cores and algorithm-specific kernels that contain logic circuits tailored for carrying out predetermined but user-configurable decoding and encoding algorithms. The interconnects between the processor cores and the algorithm-specific kernels are also user-configurable. Thus, the same hardware can be reconfigured for many different wireless communication standards.

An apparatus for reducing storage requirements and for allowing reuse of multiple rake fingers in a spread spectrum system includes a decimation circuit having an associated decimation factor, a memory coupled to the decimation circuit, and an interpolation circuit having an interpolation factor coupled to the memory. The decimation circuit decimates the sampling rate of received data to produce a decimated rate. The received data is stored in the memory at the decimated rate. The decimated rate is later increased by the interpolation circuit by the interpolation factor when the stored data is retrieved from the memory. The memory is a circular buffer or a single port RAM that is accessible by multiple rake fingers substantially simultaneously via selector circuits.

A rake receiver in accordance with an exemplary embodiment of this invention is configurable by an external agent (e.g., microcontroller, DSP, or state machine) to suit the particular requirements of different spread spectrum systems. In an exemplary embodiment, the receiver includes multiple fingers. Each finger includes a plurality of generic despreaders/descramblers, a plurality of generic dechannelizers coupled to the despreaders/descramblers, and at least one timing estimation controller coupled to the despreaders/descramblers. The finger also includes at least one phase estimation controller, at least one frequency estimation controller, and at least one energy estimation controller all coupled to the generic dechannelizers.
