Abstract:
A system for providing an assembler for a microprocessor has a file which contains data describing the instruction set of the microprocessor. A translation device for translating into machine language accesses the instruction set descriptors to constrain the machine code output of the assembler to conform to the architecture of the instruction set.
Abstract:
A WLAN communication system and algorithm that adaptively changes the data transmission rate of a communication channel based on changing channel conditions. The WLAN communication system or algorithm has two modes being a searching mode and a transmission mode. Furthermore, the WLAN communication system or algorithm incorporates an additive increase, multiplicative decrease (AIMD) function into the rate adaptation algorithm.

Abstract:
The pointing device is used in connection with a computer system, and has a sensor for sensing data representing a displacement information in at least two spatial coordinates. The device is capable of toggling between a first and a second mode of operation, and also adjusting the displacement information referring to a first of the two spatial coordinates (i.e. first displacement information) in view of a second of the two spatial coordinates (i.e. second displacement information) when the second mode of operation is activated.
Abstract:
Methods and device for in-system firmware update in an information output device are provided. In one aspect, a method of firmware update in a display device receives a set of data in an image format through a video signal input channel of an input port of the display device. The set of data is converted from the image format to an instruction set format that is different from the image format. A first set of instructions that is used to operate the display device is updated with the set of data in the instruction set format.
Abstract:
A removable wafer expander for die bonding equipment for a singularized wafer supported by a flexible sticky substrate, the removable wafer expander provided with a first ring member to be coupled with a second ring member for remote expansion of the flexible sticky substrate therebetween before the mounting of the wafer expander onto the die bonding equipment.
Abstract:
A radio frequency (RF) front end circuit includes a transformer coupled to a switch. The transformer converts a balanced transmit signal to an unbalanced transmit signal and converts an unbalanced receive signal to a balanced receive signal. The switch is configured to operate in first and second states. In the first state, the switch receives the unbalanced transmit signal from the transformer and transfers the unbalanced transmit signal to an amplifier and receives an amplified transmit signal from the amplifier and transfers the amplified transmit signal to a band pass filter. In the second state, the switch receives a filtered receive signal from the band pass filter and transfers the filtered receive signal to the transformer.
Abstract:
Very small size true directional couplers have a coupling coefficient that is independent on load VSWR. The coupler uses coupled inductors with a compensation circuit including a resistor and a capacitor, or just a capacitor. Wideband operation is suitable for many portable applications such as power detection and control for GSM, DCS-PCS, CDMA/WCDMA, Bluetooth, and WLAN systems.
Abstract:
A method for data communication includes providing an order for assigning bits of an input data stream to tones in a multi-tone modulation scheme, and allocating respective bit-loading values to the tones, such that some of the tones are allocated a first bit-loading value and other tones are allocated at least one second bit-loading value. The order is modified so as to form pairs of the tones that are allocated the first bit-loading value, with one or more of the other tones intervening between at least some of the pairs. The input data stream is modulated by assigning the bits to the tones in accordance with the modified order and the respective bit-loading values, and encoding the bits that are assigned to each of the pairs of the tones as a constellation point.
Abstract:
An image plane includes a plurality of pixels. Each pixel comprises a photodiode and two transistors, and each pixel is connected by a signal bus to a respective storage node located off the image plane. Each storage node comprises two capacitors and associated switches. One of the transistors applies a reset pulse to the pixel, and the other transistor connects the pixel to a given conductor of the signal bus, which is then connected to the storage node. The pixel transistors can be operated simultaneously, and the sensed values can subsequently be transferred from the storage nodes sequentially.
