Systems and methods for object localization and path identification based on RFID sensing

US Patent 7,898,419
March 1, 2011
A networked radio frequency identification system includes a plurality of radio frequency identification (RFID) tag readers, a computer in signal communication with the RFID tag readers over a network, and a software module for storage on and operable by the computer that localizes RFID tags based on information received from the RFID tag readers using a network model having endpoints and oriented links. In an additional example, at least one of the RFID tag readers includes an adjustable configuration setting selected from RF signal strength, antenna gain, antenna polarization, and antenna orientation. In a further aspect, the system localizes RFID tags based on hierarchical threshold limit calculations. In an additional aspect, the system controls a locking device associated with an access point based on localization of an authorized RFID tag at the access point and reception of additional authorizing information from an input device.

Adjustable threaded cores for LED thermal management

US Patent 7,898,077
March 1, 2011
Adjustable threaded cores for LED thermal management. The cores provide a direct thermal path between a LED and a heat sink while minimizing gaps and stresses between materials. The system includes a heat generating object, a first substrate housing containing a threaded hole beginning adjacent to the heat generating object, a second substrate having compatible threading with the threaded hole, and a third substrate including a heat sink. The second substrate has a higher thermal conductivity in comparison to the first substrate. The threaded hole and threaded core may terminate adjactent to the heat sink or may extent into the heat sink.

Child carrier

February 22, 2011
The ornamental design for the child carrier, as shown and described.

Enhanced aircraft transponder reliability

US Patent 7,893,863
February 22, 2011
An aircraft system includes a transponder and a processor. The processor is configured to determine if the aircraft is positioned in a predetermined restricted flying zone. If the aircraft is positioned in a predetermined restricted flying zone, the processor determines if the transponder is functioning in a transmit mode. If the transponder is not functioning in a transmit mode, the processor sets the transponder to function in a transmit mode.

Outdoor light with positionable solar collector

US Patent 7,891,832
February 22, 2011
A solar powered lighting system provides a lighting element assembly having a lighting element and a diffuser that secures near the upper end of a support. A collector unit contains a solar cell and a coupler such as a clip-on clamp which allows the collector unit to be selectively attached to a desired support. The lighting system includes a battery electrically coupled to the solar cell of the collector unit and to the lighting element assembly using a wire such that the portion of the wire that extends from the collector unit to the lighting element assembly is of sufficient length to allow the collector unit to be selectively positioned on or remotely from the support.

Ground operations and advanced runway awareness and advisory system

US Patent 7,890,248
February 15, 2011
A device, method and computer program product for locating aircraft with respect to airport runways and taxiways, determining if a conflict exists between an aircraft having operating the invention and another aircraft, and generating and annunciating conflict awareness advisories as a function of determining that a conflict exists.

Radar target processing reduction systems and methods using cooperative surveillance sources

US Patent 7,889,114
February 15, 2011
Systems and methods for reducing radar target processing. The systems include a processor configured to receive a first input from a cooperative surveillance source and a second input from a radar device. The first input includes cooperative target information, the second input includes cooperative and non-cooperative target information, and the processor is configured to process the first and second inputs to remove cooperative target information from the second input based on the first input to generate a modified radar output for use by an output device. The methods include receiving a first input including cooperative target information from a cooperative surveillance source, receiving a second input including cooperative and non-cooperative target information from a radar device, processing the first and second inputs to remove cooperative target information from the second input based on the first input, and generating a modified radar output based on the processed first and second inputs.

Durable digital writing and sketching instrument

US Patent 7,884,811
February 8, 2011
A hand-holdable, durable digital writing and sketching device or assembly having rugged construction that houses an on-board camera with a view through an optical window of a writing surface brought in view by a user moving the device. The device is rugged, sealed, and is capable of withstanding dropping, water submersion, abrasive incursions, and resistance to chemical and fungal degradation. The optical window and optic channel to the camera is protected by a durable and replaceable light-transmitting shield that provides a sealed barrier to the environmental elements harmful to the functioning of the device. The writing and sketching device oscillates between a stowed and a deployed state. The deployed state includes the camera being in view the writing surface and the stowed state includes the camera being either masked from viewing the writing surface or aimed internally from viewing the writing surface. Other versions of the digital writing and sketching device include replaceable styli and pens that are removable and interchangeable with a sealed chamber in the device. The stylus point or pen ends are substantially in view of the on-board device camera. Signal transmissions communicated from the digital writing and sketching device convey pressures experienced by the inserted stylus or pens and are represented in proportion to a microprocessor based display that conveys changing field of view experienced by the on-board camera.

Repetitive fence for cross-cutting materials

US Patent 7,882,772
February 8, 2011
A repetitive fence utilizes a plurality of telescoping arms driven by a metal tape of the tape measure type to position a stop member at a desired location from a saw blade. A user can position a work piece, such as board lumber against the stop member to repeatedly position the work piece at a desired cut dimension with respect to a saw blade. The repetitive fence preferably employs a plurality of telescoping arms to position the stop member at the desired location, and an electronic read-out provided to indicate to the user the position of the stop member with respect to the saw blade. The telescoping arms can be motivated by electronic devices, such as an electric motor, or by a manual crank.
