摘要： 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.

摘要： A communication protocol that is configured to extend the battery life of devices that monitor and/or affect body parameters and is particularly useful in a system comprised of a system control unit (SCU) and one or more implanted devices. Each such implanted device is configured to be monitored and/or controlled by the SCU via a wireless communication channel. The time between battery rechargings is determined by the battery capacity and the device's power consumption. Accordingly, the present invention reduces their average power consumption by reducing the usage duty cycle of their power consuming transmit and receive modes used to communicate with the SCU. By dedicating addressable time slots to each of the implantable devices in the system and limiting their use of receive and transmit modes to time periods proximate to these time slots, the average power consumption is accordingly reduced.

摘要： A round-trip, spread-spectrum navigation and locating system achieves high capacity and large processing gains in one-to-many and many-to-one configurations using round-trip signaling with frequency division based upon precise responding device carrier frequency offsets. Reduced cross-correlation is achieved by assigning these very small disparate frequency offsets to replies from interrogated devices so that the long-term correlation between disparate reply sequences is reduced almost to that of random noise of equivalent energy. The invention supports simultaneous interrogation of multiple responding devices, which responding devices respond essentially simultaneously at a fixed delay after receiving the query. The originating and/or responding devices may be fixed or mobile, permanently or temporarily deployed, terrestrial, airbourne or space-based with any source of power including batteries and solar without limitation. The signaling may be electromagnetic or acoustic with the potential for under-water use.

摘要： An improved two-way tagging tracking and locating system uses time of arrival (TOA), Doppler, and angle of arrival (AOA) in conjunction with remote tags and a locator. The locator's antenna is tethered to a central point, and moved in a constrained motion so that it describes a roughly circular horizontal path. The locator transmits and receives sets of complex radio sequences to/from the tag(s) so that the tag(s) emit signals which are phase, chip, and symbol coherent with the received locator signals. This enables the locator to determine the distances and Doppler shifts between itself and the tag(s) at various positions in its path such that, by post correlation processing of complex captured signal sequences, aims a virtual phased array antenna at the tag(s), resulting in enhanced distance and direction measurements. The angular position of the orbiting locator's antenna may be measured using an electronic compass packaged with the antenna.

摘要： A system for locating a debris field resulting from a plane crash comprises a plurality of low-power, battery operated electronic transponder tags, and at least one locator operative to the interrogate the tags to determine the location thereof. The tags are placed on or in an airplane in multiple locations, thereby enabling the locator to determine the location of a debris field in the event of a crash. The locator, which may be airborne, preferably reports tag positions for map display. The tags may be hermetically sealed to prevent water infiltration, and may be triggered to an active state in response to a large acceleration or always in an ON state. Tags placed on or in the airplane may be mounted in a manner to intentionally detach. The tags may further include a barometric pressure sensor, a shock sensor and/or an accurate time base to record the time of a crash.

摘要： A secure communication topology can be used for communications between a locator and one or more transponders to determine the location of the transponders. An example system may include a locator that is configured to transmit an interrogation signal that is encoded for receipt by one or more of the transponders. When a transponder receives and correlates the interrogation signal with an internally stored reference sequence, the transponder can transmit one or more reply transmissions at precisely determined time delay intervals. The time delay intervals are secretly known by both the locator and the transponder. The reply transmissions can each correspond to previously sampled noise signals that are also secretly known by both the transponder and the locator.

摘要： An apparatus and method is related to providing sensing functions that are similar to “human touch” when located in a prosthetic device such as a BION microstimulator that is implanted in a patient. The apparatus includes a power circuit, a communication circuit, and a sensor circuit. The power circuit provides power to the communication circuit and the sensor circuit. The sensor cooperates with the communication circuit, which communicates to the brain. The sensor uses various techniques to detect changes in the environment for the surrounding tissue using criteria such as reflectivity, impedance, conductivity, return signal spectrum, return signal rate, and return signal phase to name a few. For example, the impedance observed by the sensor changes when: the skin tissue is deformed around the sensor, or when the skin is surrounded by water. The sensory information is interpreted by the brain as an analog of touch or feel.
