International Classification:

A01K 1/03

US Classification:

119421

Abstract:

Systems and methods for monitoring laboratory animals includes a tag comprising an inductive element and a capacitive element attached to a portion of a laboratory animal. The position of the portion is detected by monitoring the effect of the tag on a time-varying magnetic field having different frequencies, one near tag resonance, and one away from tag resonance.

US Patent:

Filed:

Jun 24, 1996

Appl. No.:

8/671143

Inventors:

Trang Diem Nguyen - Saratoga CA

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06G 748

US Classification:

3955001

Abstract:

A wafer-disposition method and apparatus are disclosed where the disposition is based on a model of systematic misalignment errors. The method comprises the steps of: modeling the misalignment errors between the mask and wafer as a mathematical model using measured misalignment data, generating a confidence limit of the probability of defect for the wafer, and determining whether the wafer satisfies a predetermined product quality level by comparing the confidence limit to the tolerance specification for the wafer. The misalignment model includes systematic errors and is represented by a polynomial based on the location of test points on the wafer. Preferably, several polynomials are formed and one that best predicts new misalignment data is selected. The confidence limit is created by combining the estimated probabilities of defect for all sliders in the wafer. Also, the product quality determination is based on a variable acceptance sampling procedure using the mathematical model.

Inventors:

Chae Lee - Campbell CA
Trang Minh Nguyen - Fremont CA
Robert Blattner - Castro Valley CA

Assignee:

Siliconix incorporated - Santa Clara CA

International Classification:

G05F 1613

US Classification:

323224

Abstract:

Multiple controllers connected in parallel to control external circuits such as dc-dc converters so that the external circuits supply power equally to a load such as a microprocessor. All of the controllers are connected and each controller includes an oscillator and a pulse width modulation circuit to synchronize the frequency of all of the oscillators such that the duty cycle of all the oscillators are equal. Each controller includes an over-current protection circuit and an over-voltage protection circuit which will cause the controller with a fault to discontinue supplying power to the load. Each controller further includes a circuit to adjust the duty cycle of the non-faulty controllers when a controller with a fault is caused to discontinue supplying power to the load.

International Classification:

G06F 1/32
H04W 52/02

Abstract:

Micro-idle power in a subsystem of a portable computing device may be actively managed based on client voting. Each client vote may include a client activity status indication and a client latency tolerance indication. Votes are aggregated to provide an aggregate client latency tolerance, which may be used to obtain a set of micro-idle time values. Micro-idle timers in the subsystem may be set to associated micro-idle time values. The micro-idle timers determine whether one or more of the micro-idle time values have elapsed. A power management policy associated with each micro-idle time value determined to have elapsed may be applied to a portion of the subsystem.

Assignee:

International Classification:

H04R 1/04

Abstract:

An electronic device may be provided with a microphone in a microphone port. A shield may cover a microelectromechanical systems microphone device on a microphone substrate. An opening in the microphone substrate may form a sound port for the microphone. The microphone port may be formed by perforations in the microphone substrate or other layers such as a flexible printed circuit layer, a sheet metal layer, a layer of adhesive, a flexible polymer carrier layer in an adhesive tape, or an electronic device housing. The perforations may be sufficiently small to help resist the intrusions of foreign material such as liquid and dirt into the sound port of the microphone. Larger openings may be formed in other structures such as an electronic device housing. The larger openings may serve as sound passageways for the microphone port while being sufficiently large to resist clogging.
