A clinical grid electrode system for seizure control through local cooling, mapping brain function and me provision of reversible functional ablation. The system includes a modular, scalable, cooling and sensing array composed of a plurality of cooling sensing elements. The system also includes a control system to which die cooling and sensing array is coupled for providing for control and monitoring of die cooling sensing elements making up the cooling and sensing array.

Methods and apparatus are provided for testing to determine the existence of defects and faults in circuits, devices, and systems such as digital integrated circuits, SRAM memory, mixed signal circuits, and the like. In particular, methods and apparatus are provided for detecting faults in circuits, devices, and systems using input control signals to generate controlled-duration, controlled pulse-width, transient power supply currents in a device under test, where said transient power supply currents are of controllable bandwidth and can be used as observables to determine faulty or defective operation. Additionally, methods and apparatus are provided to permit high bandwidth sensing of transient supply currents as need to preserve the narrow widths of these current pulses. These methods may include autozero techniques to remove supply current leakage current and DC offsets associated with practical current sensing currents. The sensed transient supply currents can be compared to single or multiple thresholds to assess normal or faulty or defective operation of the device under test.

Methods and apparatus for testing electronic circuits

A proximity detection system for determining when a single channel receiver becomes proximate to any point on a wireless closed boundary continuously generated by a transmitter. The transmitter includes a magnetic field generator broadcasting a composite, modulated, time-varying magnetic field signal of a particular carrier frequency. The receiver forms a measure of the broadcast magnetic field intensity incident to the location of the receiver or a measure of the power or energy of incident field.

Wireless boundary proximity determining and animal containment system and method

A continuous-time baseline restoration (BLR) circuit providing built-in pulse tail-cancellation, or BLR tail-cancel circuit, in constant fraction discriminator (CFD) arming and timing circuits. The BLR tail cancel circuit is applied at the output of constant fraction timing shaping filters and arming circuits to permit monolithic integrated circuit implementation of CFD circuits operating at high input signal count rates. The BLR tail-cancel circuit provides correction of dc offset and count-rate dependent baseline errors along with simultaneous tail-cancellation. Correction of dc offsets due to electronic device mismatches and count-rate dependent baseline errors is required for accurate time pickoff from the input signals. The reduction of pulse width, or pulse tail-cancellation is required to shorten the duration of high count rate signals to prevent the severe distortion caused by the occurrence a new signal superimposed on the tails of previous signals, a condition known as pulse pileup. Without pulse tail-cancellation, there are substantial errors in time pickoff due to the pulse pileup.
