Sensor isolation system
Patent # 7679171 B2    Date Issued:  March 16, 2010

A sensor isolation system including a sensor, a package for the sensor, and a compliant interposer disposed between the sensor and the package and interconnecting the sensor to the package to isolate the sensor from thermal and mechanical stresses and yet at the same time providing a physical interconnect between the sensor and the package.

Systems and methods for positioning using multipath signals
Patent # 7679561 B2    Date Issued:  March 16, 2010

A signal processing technique for RF active, passive, or aided localization approaches that utilizes multipath signals as additional measurements with a filter or estimator, e.g., a nonlinear filter. The filter uses indirect and direct path measurements or any other available signals to build parametric models of observable indirect paths. If one or more direct path measurements are subsequently lost (e.g., due to obstruction), the filter maintains an estimate of the position of the person or object of interest using indirect path measurements.

Method of determining toxicity with three dimensional structures
Patent # 7670797 B2    Date Issued:  March 2, 2010

A method of determining toxicity of a test agent in a tissue including A) incubating a test agent within a three-dimensional tissue engineered structure comprising a first mold or polymer scaffold, a semi-permeable membrane, and a second mold or polymer scaffold, wherein the semi-permeable membrane is disposed between the first and second molds or polymer scaffolds, and wherein the first mold or polymer scaffold has microchannels comprising vessels that bifurcate, and B) obtaining information from step A) to assess toxicity.

Systems and methods for reconfigurable computing
Patent# 7669035 B2    Date Issued:  February 23, 2010

A processing system includes a communication bus. a controller, an Input/Output ("I/O") block, and reconfigurable logic segments (e.g., reconfigurable units). Individually reconfigurable logic segments are part of a single chip. A communication bus is in electrical communication with the logic segments. A first logic segment communicates to a Second logic segment over the communication bus. Reconfiguration can partition a first logic segment into a second and a third logic segment where the smaller logic segments are in electrical communication with the communication bus. Resources are dynamically reallocated when reconfigurable units are either combined or partitioned. More specifically, both partitioning a logic segment and combining two or more logic segments can change the bus width allocated to a reconfigurable unit and the quantity of logic gates in the reconfigured unit. As a result of a reconfiguration, a logic segment's embedded resources can change. The processing system provides high chip utilization throughout the chip's operation.

MEMS devices and interposer and method for integrating MEMS device and interposer
Patent # 7655538 B2    Date Issued:  February 2, 2010

A method for producing Microelectromechanical Systems (MEMS) and related devices using Silicon-On-Insulator (SOI) wafer includes providing an SOI wafer, performing a mesa etch to at least partially define the MEMS device, bonding the SOI wafer to an interposer by direct bonding, removing the handle layer of the SOI wafer, removing the oxide layer of the SOI wafer, and further etching the device layer of the SOI wafer to define the MEMS device. A structure manufactured according to the above described processes includes an interposer comprising an SOI wafer and a MEMS device mounted on the interposer.  The MEMS device comprises posts extending from a silicon plate. The MEMS device is directly mounted on the interposer by bonding the posts of the MEMS device to the device layer of the interposer.
