Filed:

Sep 19, 2003

Appl. No.:

10/665991

Inventors:

Henry V. Allen - Fremont CA, US
Stephen C. Terry - Palo Alto CA, US
James W. Knutti - Fremont CA, US

Assignee:

Silicon Microstructures, Inc. - Milpitas CA

International Classification:

G01L 7/08
G01L 9/00

US Classification:

73715

Abstract:

Methods and apparatus for an absolute or gauge pressure sensor having a backside cavity with a substantially vertical interior sidewall. The backside cavity is formed using a DRIE etch or other MEMS micro-machining technique. One embodiment provides for a diaphragm having a boss manufactured using a two step process that results in a boss thickness that is independent of the thickness of the starting material. Another provides for various shapes to the backside cavity that reduces the likelihood of crystalline fractures while focusing stress on piezoresistive sensing elements. Another provides for a sensitivity adjustment by thinning the insulating and silicon layers that form the sensor diaphragm. A pressure sensor according to the present invention may incorporate one or more of these, or may incorporate other elements discussed herein.

International Classification:

H04W 72/04

US Classification:

370329

Abstract:

A method and apparatus are described for implementing a reset procedure for radio link control (RLC) using radio resource control (RRC) signaling. A wireless transmit/receive unit (WTRU) receives a request for RLC reset. A processor at the WTRU comprises a RRC entity and a RLC entity. The RRC entity receives the request for a RLC reset in a radio resource control message. The RLC entity reassembles RLC service data units (SDUs) from any protocol data units (PDUs) that are received out of sequence at a receiving side of the RLC entity. The reassembled SDUs are delivered in sequence to a packet data convergence protocol entity (PDCP). At the receiving side of the RLC entity, any remaining PDUs that are not able to be reassembled are discarded. At a transmitting side of the RLC entity, all SDUs and PDUs stored in transmit buffers are discarded.

International Classification:

H04W 28/02

US Classification:

3702351

Abstract:

A method and apparatus for uplink (UL) starvation avoidance includes determining a current buffer status information. The current buffer status information is reported to an evolved Node B (eNB). A grant that includes a determination of a number of tokens a wireless transmit/receive unit (WTRU) may accumulate is received from the eNB.

US Patent:

Filed:

Jun 22, 1989

Appl. No.:

7/370364

Inventors:

Henry V. Allen - Fremont CA
Stephen C. Terry - Palo Alto CA
Diederik W. De Bruin - Santa Clara CA

Assignee:

IC Sensors, Inc. - Milpitas CA

International Classification:

G01P 2102

US Classification:

73 1D

Abstract:

An apparatus and method of operation for a self-testable accelerometer having a housing, a diaphragm for detecting movement in response to an applied force, a mass on the diaphragm, at least one capacitive plate attached to the housing and disposed such that a potential difference between the capacitive plate and the mass causes a movement of the mass, electrodes for applying a potential difference between the mass and the capacitive plate, and at least one piezoresistive element attached to the housing and the diaphragm for sensing movement of the mass. The accelerometer's housing comprises a frame, a base and a cap with air gaps providing squeeze film damping and mechanical stops for inhibiting movements of the mass. The combination of the capability to electrostatically produce a movement of the mass and the piezoresistive sensing of that movement allows testing and calibration of the accelerometer at any stage in its manufacture or deployment without the need for external equipment such as shakers.

Appl. No.:

6/371617

Inventors:

Stephen C. Terry - Palo Alto CA
John H. Jerman - Palo Alto CA

Assignee:

Microsensor Technology Inc. - Fremont CA

International Classification:

G01N 3108
B01D 5300

US Classification:

436161

Abstract:

A gas chromatography assembly has a substrate wafer with grooves and a valve seat etched therein. A plate cooperates with the wafer and the grooves to define gas channels: a carrier gas channel and a sample gas channel, each passing through the valve seat. A valve actuator is attached to the valve seat for controlling the flow of sample gas from the sample gas channel into the carrier gas channel. A pump is attached to the wafer and is connected to the sample gas channel. The pump cooperates with the valve actuator to inject sample gas from the sample gas channel into the carrier gas channel. A modular capillary tube and a detector are connected to the carrier gas channel to analyze the properties of the sample gas flowing in the carrier gas channel from the sample gas channel.
