Appl. No.:

11/416445

Inventors:

Wei H. Koh - Irvine CA, US
John Ho - Trabuco Canyon CA, US

Assignee:

Kingston Technology Corporation - Fountain Valley CA

International Classification:

G08B 13/14

US Classification:

3405728, 3405721, 3405727, 235492

Abstract:

A dual in-line memory module (DIMM) and a digital flash card are disclosed including an internal, built-in RFID tag in which identification and product information is contained. The RFID tag has an RF integrated circuit chip and antenna traces spreading outwardly therefrom to permit access to the information contained by the RF chip. In the case of a DIMM, the RF integrated circuit chip and its antenna traces are located on top of or between the layers of a multi-layer laminated printed wiring board substrate. In the case of a digital flash card, the RF integrated circuit chip and its antenna traces are preferably located on top of a multi-layer printed wiring board substrate and then encapsulated within a molded cover. In the alternative, the RF chip and its antenna traces are attached to the inside of a cover that extends over and is spaced above the printed wiring board substrate.

Appl. No.:

12/800301

Inventors:

Peter Lee Kuo Chou - Orange CA, US
Shing Kuo Tam - Cerritos CA, US
John Pei Ho - Trabuco Canyon CA, US

Assignee:

Kingston Digital, Inc. - Fountain Valley CA

International Classification:

H01R 13/44

US Classification:

439131

Abstract:

A mechanism for extending and retracting the electrical connector in a flash memory thumb drive is disclosed. The flash memory and USB connector are disposed on a printed circuit board. The board is slidably disposed within a housing so that the connector can be extended beyond and retracted within the housing. An arm on a pivot can be rotated in one direction so that another lever extends the board, and rotated in the opposite direction to retract it.

John Pei Ho - Trabuco Canyon CA, US

Assignee:

Kingston Technology Corp. - Fountain Valley CA

International Classification:

H01R 13/00

US Classification:

43962021

Abstract:

A thumb drive with a miniaturized memory storage assembly package that employs an extended chassis structure to support the miniaturized memory device within an ergonomically designed casing that is also simple to manufacture. The miniaturized memory storage assembly has a flexible latch projection extending from its side that mates with a complimentary latch aperture in the side of the connector housing. Downwardly projecting tongues in the top surface of the connector housing also prevent movement of the assembly within the housing. The elongated platform chassis extending rearwardly from the USB connector housing snaps in place in an ergonomically designed thumb drive case.

Assignee:

Raytheon BBN Technologies Corp. - Cambridge MA

International Classification:

G01N 21/76

US Classification:

436172, 422 681

Abstract:

Systems, devices and methods for remotely interrogating sensor electronics are described. In one embodiment, a system for detecting and localizing chemical analytes is described. This system includes a plurality of chemosensor electronic devices for detecting the presence of chemical analytes. Each of these devices includes a chemosensor for sensing chemical analytes, a transponder, and an electronic circuit for activating the transponder based on an output of the chemosensor. These devices may have a cross-section area of less than 1 square micrometer. The system also includes an interrogation device for interrogating the plurality of devices and for receiving information on the detected chemical analytes from devices with activated transponders, and a processor for determining the locations of the devices with activated transponders. These locations may be forwarded to a third party.

International Classification:

G01N 15/02
G01N 15/14
G01N 21/53

Abstract:

A device for monitoring a bioreactor is configured for in-situ analysis, e.g., by NIR, without the need for withdrawing a sample into a sample cell or into an ex-situ arrangement. The device can be inserted into a port of the bioreactor and provides a sample detection region defined by an optical element such as a lens and a photodetector. The electrical signal obtained from a photodetector that is part of the device can be directed to an analyzer via a detachable electrical connection.
