Publication number: 20060229694Abstract: An implantable substrate sensor has electronic circuitry and electrodes formed on opposite sides of a substrate. A protective coating covers the substrate, effectively hermetically sealing the electronic circuitry under the coating. Exposed areas of the electrodes are selectively left uncovered by the protective coating, thereby allowing such electrodes to be exposed to body tissue and fluids when the sensor is implanted in living tissue. The substrate on which the electronic circuitry and electrodes are formed is the same substrate or “chip” on which an integrated circuit (IC) is formed, which integrated circuit contains the desired electronic circuitry. Such approach eliminates the need for an hermetically sealed lid or cover to cover hybrid electronic circuitry, and allows the sensor to be made much thinner than would otherwise be possible. In one embodiment, two such substrate sensor may be placed back-to-back, with the electrodes facing outward.Type: ApplicationFiled: March 29, 2006Publication date: October 12, 2006Inventors: Joseph Schulman, Charles Byers, John Gord, Rajiv Shah, Lyle Canfield

Patent number: 7015769Abstract: An automatic tuning system for a magnetic field generating tuned circuit includes a processor configured to maintain the resonant frequency of a tuned circuit equal to a reference frequency. The tuned circuit is driven by a power amplifier whose output provides an amplified signal at the reference frequency. The tuned circuit includes a magnetic field generating inductor and a bank of individually switchable capacitors controlled by the processor capable of adding and removing the respective capacitances to and from the tuned circuit. The inductor includes a Faraday shield to shield the tuned circuit from the influence of electric fields. A power sense circuit monitors the power delivered by the power amplifier to the tuned circuit and the processor sequentially switches the capacitors in a binary progression format to achieve maximum power delivery indicative of conforming the resonant frequency of the tuned circuit to the reference frequency.Type: GrantFiled: May 5, 2003Date of Patent: March 21, 2006Assignee: Alfred E.

Patent number: 6667923Abstract: An apparatus and method for forming a RAM data memory that generates predictable noise/interference components that are coherent with each write cycle and essentially independent of the data content of the RAM data memory. The RAM data memory is comprised of a plurality of cells, each representing a data bit, which are selectively addressable as memory bytes formed of multiple bits. Each cell is formed of two sets of cross-coupled transistors. By causing each set of cross-coupled transistors to be set to a common voltage level at the beginning of a write cycle before setting one set of transistors to a low level and the one set of transistors to be set to a high level (thus representing a desired data bit value), the associated noise/interference components of the power drain are data independent. Furthermore, the data-independent noise occurs at frequencies at or above the write cycle rate.Type: GrantFiled: July 26, 2002Date of Patent: December 23, 2003Assignee: Alfred E.
