US Patent:

7667468, Feb 23, 2010

Filed:

Jul 24, 2007

Appl. No.:

11/880963

Inventors:

Erik Anderson - Shoreline WA, US

Assignee:

Cypress Semiconductor Corporation - San Jose CA

International Classification:

G01R 27/26

US Classification:

324676, 324678, 324679

Abstract:

A capacitive sensor with ratiometric voltage references includes a voltage source, a charge transfer switch, an integrating capacitor, and a comparator. The voltage source is configured to generate a first voltage reference and a second voltage reference in response to a supply voltage, where the first voltage reference changes proportionally to the second voltage reference in response to a change in the supply voltage. The charge transfer switch is coupled to the integrating capacitor to distribute charge between a sensing capacitor and the integrating capacitor, where the charge is accumulated in response to the first voltage reference. The comparator is coupled to the second voltage reference and the integrating capacitor to compare a voltage on the integrating capacitor against the second voltage reference.

Assignee:

SHTC Holdings LLC - Montesano WA

International Classification:

G06F 15/173

US Classification:

709224, 709203, 709217, 709218, 709223, 709230, 709231

Abstract:

A method and apparatus to compare a control article against a test article to support a product or service is disclosed. A client indicates a selection of the test article to be compared with the control article. The articles are fed to multiple end users in response to requests from the end users. The requests or responses are tracked to determine whether the control article or test article has more negative or positive responses. The control article may then be replaced with the test article as a primary article to support the product or service if the test article has a predetermined amount of positive or negative responses when compared with the control article to increase efficiency in supporting the product or service.

International Classification:

G06F015/163
G06F009/00
G06F015/16
G06F009/54

US Classification:

709/100000, 709/310000, 709/106000

Abstract:

One embodiment of the present invention provides a mechanism that associates a virtual server identifier with a process in an operating system, wherein the operating system supports multiple virtual servers running within multiple virtual environments. Upon receiving a call to an operating system function from the process, the system looks up an identifier for a virtual server associated with the process. If the identifier exists, the system uses the identifier in performing the operating system function, so that the operating system function accesses only objects defined within a virtual environment associated with the virtual server, and does not access objects defined outside the virtual environment In one embodiment of the present invention, the system receives a command to initialize a new process. If the new process is being initialized within a target virtual environment associated with a target virtual server, the system assigns an identifier for the target virtual server to the new process.

Assignee:

CYPRESS SEMICONDUCTOR CORPORATION - San Jose CA

International Classification:

G01R 27/26

US Classification:

324679, 324658

Abstract:

A capacitance sensing system can include a noise detector coupled to a capacitance sensing network that generates a noise detect signal in response to noise; a delay circuit coupled to generate at least two different delayed sense signals in response to outputs from the capacitance sensing network; and a switch circuit that selectively outputs one of the delayed sense signals in response to the noise detect signal. Particular embodiments can include selectively discarding discrete analog samples of a capacitance signal when noise is detected in such a sample.
