Filed:

Nov 25, 2003

Appl. No.:

10/723381

James L. Say - Alameda CA, US

Assignee:

TheraSense, Inc. - Alameda CA

International Classification:

A61B005/05

US Classification:

600347, 600345, 600365, 600373

Abstract:

An in vivo electrochemical sensor including a working electrode, and an analyte-responsive sensing layer proximate the working electrode. The sensing layer is exposed at an edge of the sensor, wherein the sensor signal is limited, at least in part, by mass transport of analyte to the sensing layer. The sensor is configured and arranged for implantation into the body of a mammal for contact with body fluids of the mammal. The analyte diffuses to the sensing element via the edge of the sensor, thereby restricting mass transport of the analyte to the sensing element. This is because the solution-contacting surface area of the sensor edge is much smaller than an open face of the sensing layer.

US Classification:

600300, 600309, 600341, 604 57, 604 59, 606182, 606185

Abstract:

An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor control unit typically has a housing adapted for placement on skin and is adapted to receive a portion of an electrochemical sensor. The sensor control unit also includes two or more conductive contacts disposed on the housing and configured for coupling to two or more contact pads on the sensor. A transmitter is disposed in the housing and coupled to the plurality of conductive contacts for transmitting data obtained using the sensor. The display unit has a receiver for receiving data transmitted by the transmitter of the sensor control unit and a display coupled to the receiver for displaying an indication of a level of an analyte, such as blood glucose. An inserter having a retractable introducer is provided for subcutaneously implanting the sensor in a predictable and reliable fashion.

International Classification:

H04B 7/00

US Classification:

340 586, 340 101, 340 1041, 3405721, 235380, 235487

Abstract:

A license detector system enables a person such as a police officer to monitor vehicles on the road to ensure drivers have valid licenses. Within each valid license is an RFID tag which contains specific information and each RFID tag is able to send that information to a detector when requested. To use the system, the police officer aims the detector at a vehicle, initiates the signal to be received by the RFID tag within the license and waits to receive a signal back from the RFID tag. If a signal is received, then a valid license has been detected within the vehicle. However, if no signal or an invalid signal is received by the detector, then no one, specifically the driver of the car, has a valid license. Upon discovering such information, the police officer should be justified in stopping the vehicle and taking the necessary police action.
