G02F001/335

US Classification:

385 7, 359308, 359285

Abstract:

This invention relates to an acousto-optical tunable filter generally of the kind described in U. S. Pat. No. 6,266,462. More specifically, the invention relates to a filter and its construction, the filter including a support, first and second mounts at spaced locations on the support, an optical fiber having first and second mounted portions secured to the first and second mounts respectively and a filtering section between the first and second mounted portions, a signal generator operable to generate a periodic signal, and an electro-acoustic transducer having a terminal connected to the signal generator and an actuating portion, the electric signal causing vibration of the actuating portion, and the actuating portion being connected to the filtering section so that the vibration generates a transverse wave traveling along the filtering section. The filter has an improved damper to more effectively dampen waves traveling along the filtering section.

US Classification:

326 38, 326 39, 370 581, 370 77, 370314, 370341

Abstract:

Integrated circuits are provided that use on-chip data compression and decompression to minimize consumption of interconnect resources. Parallel-to-serial converter circuitry can use time-division multiplexing techniques to compress data. The compressed data may be conveyed between circuit blocks on the integrated circuit using a reduced number of parallel interconnect conductors. After the compressed data has been conveyed to its destination, a serial-to-parallel converter may use time-division demultiplexing techniques to decompress the data. Interconnect resources may be shared by dedicated circuits. With this arrangement, signals can be selectively steered through the appropriate dedicated circuitry to either maximize performance or to use compression and decompression to minimize interconnect resource consumption.

Appl. No.:

9/020590

Inventors:

Kwan Yee Lee - San Francisco CA

Assignee:

Analog Devices, Inc. - Norwood MA

International Classification:

H04L 2302

US Classification:

375265

Abstract:

A trellis decoding system is provided having a memory for storing a sequence of received signals. The signals have been encoded prior to transmission by a trellis encoder such that each of a predetermined plurality of symbols represents an allowed transition from an originating state to a predetermined limited number of terminating states. The system includes a trellis decoder for decoding the sequence of received signals into a corresponding sequence of the symbols. A soft decision generator is provided. The soft decision generator is responsive to the signals stored in the memory and to the output of the trellis decoder and determines a soft decision parameter representative of confidence level of the trellis decoder in properly decoding the received signal into each one of the symbols. The determined soft decision parameter is tagged to each one of such symbols subsequent to the trellis decoder decoding the sequence of received signals into the corresponding sequence of symbols.

Abstract:

A touch panel for a display may include a touch sensor with a plurality of electrode traces. A first portion of the plurality of electrode traces may form sensing lines configured to receive touch input. The touch sensor includes an edge dummy area between an edge of the touch sensor and an electrode trace of a remaining portion of the plurality of electrode traces. The edge dummy area may be located outside of the sensing lines. The touch panel may further include an antenna with a radiation structure and a ground structure. The radiation structure may be located within a routing traces area outside of the touch sensor. The ground structure may be located within the edge dummy area. The ground structure may include an electrode trace of the plurality of electrode traces located within the edge dummy area of the touch sensor.

Abstract:

Technologies for the calibration of a body presence sensor include a mobile computing device configured to calibrate the body presence sensor based on a present physical configuration mode of the mobile computing device. The mobile computing device may be adjustable into multiple physical configuration modes based on the intended use of the mobile computing device. The mobile computing device controls a transmit power level of an associated communication circuit based on whether the body presence sensor detects a body presence within proximity to the mobile computing device.
