摘要： A low power miniaturized telemeter (25, 40-42) provides data from a monitored subject at internal or external locations. A charge integration and pulse stream encoding (30) in the telemeter (25, 40-42) contributes to reduced power consumption. A transmitter (29) in the telemeter (25, 40-42) may be omnidirectional to permit operation without physical obstruction or limitations to movement. A receiver (22) collects transmitted information and may have an adaptive threshold pulse detector to permit further reductions in power usage. The telemeter (25, 40-42) can multiplex monitored parameters on a time division basis to permit trans-mission of multiple data channels. Individual telemeters may have unique transmission frequencies to permit multiple telemeters to be used concurrently without interference. A self-contained power source in the telemeter (25, 40-42) permits long term operation at low power without the need of replacement. The telemeter (25, 40-42) can be packaged to accommodate a number of applications, such as by permitting adjustable density.

摘要： Provided are methods for forming a fluorocarbon polymer thin film on the surface of a structure. In one method, a monomer gas is exposed to a source of heat having a temperature sufficient to pyrolyze the monomer gas and produce a source of reactive CF.sub.2 species in the vicinity of the structure surface. The structure surface is maintained substantially at a temperature lower than that of the heat source to induce deposition and polymerization of the CF.sub.2 species on the structure surface. In another method for forming a fluorocarbon polymer thin film, the structure is exposed to a plasma environment in which a monomer gas is ionized to produce reactive CF.sub.2 species. The plasma environment is produced by application to the monomer gas of plasma excitation power characterized by an excitation duty cycle having alternating intervals in which excitation power is applied and in which no excitation power is applied to the monomer gas. The monomer gas employed in the methods preferably includes hexafluoropropylene oxide. The monomer gas pyrolysis and plasma excitation methods can be carried out individually, sequentially, or simultaneously. Flexible fluorocarbon polymer thin films can thusly be produced on wires, twisted wires, neural probes, tubing, complex microstructures, substrates, microfabricated circuits, and other structures. The thin films have a compositional CF.sub.2 fraction of at least about 50%, a dielectric constant of less than about 1.95, and a crosslinking density of less than about 35%.

摘要： A precision current source is disclosed that includes a voltage setting circuit that precisely sets the voltage across a range setting resistor to set the current flowing in a load resistance connected in series with the range setting resistor. The voltage setting circuit precisely sets the voltage across the range setting resistor as a function of an input reference voltage. The voltage setting circuit includes an instrumentation amplifier that determines the voltage across the range setting resistor and the difference between this voltage and the reference voltage is used drive a drive voltage amplifier. The drive voltage amplifier output adjusts to minimize the difference between the reference voltage and the voltage across the range setting resistor. Other embodiments include the use of a DC blocking capacitor to allow only AC coupling and various nulling. circuits to remove any charge buildup on a DC blocking capacitor.

摘要： A long term bi-directional axon-electronic communication system that provides signaling capability at the level of individual nerve fascicles, bundles of axon and even axons is disclosed. The bi-directional communication system is a modular approach for achieving a chronic enduring interface to peripheral or central nerve atoms for the purpose of restoring function to disabled persons or animals with sensory and/or motor impairments. One embodiment of the communication system includes a multi-channeled nerve-muscle graft chamber for making the nerve-muscle connection. Another embodiment includes a regeneration based microtube nerve interface for bi-directional communication. The interface communication system permits amputees to obtain simultaneous control of multi-degree of freedom powered prostheses by means of naturally produced neural activity from the stamps of the amputated nerves in their residual limbs.

摘要： An apparatus and corresponding method for providing data communications to and from a location within a body cavity in which an internal transmitter receives a first data stream from an in vivo sensor, electrode, or transducer. The internal transmitter is configured and arranged to asynchronously modulate the first data stream and to provide as an output a first optical signal carrying the asynchronously modulated first data stream. The apparatus further includes an external receiver that is configured and arranged external to the body cavity such that an optical input to the external receiver is optically coupled to the internal transmitter output and receives the optical signal therefrom. The external receiver asynchronously demodulates the received optical signal and provides as an output at least one signal indicative of the first data stream.

摘要： A low-pressure neural contact structure for contact with neural tissue, for example, neural tissue of the retina within which are ganglion cells to be electrically stimulated. The contact structure comprises a first portion for attachment to a first bodily location, such as the inner surface of the retina, and a second portion interconnected with the first portion via an interconnection and being held in contact with the neural tissue. The interconnection exhibits a weak restoring force which in conjunction with the geometry of said second portion provides a preselected desired pressure of contact against the neural tissue. As adapted for the retina, the interconnection exhibits a weak restoring force developed in response to curvature of the interconnection along the inner radius of the retina.
