Title: Transcutaneous energy and information transmission apparatus
Inventor: PREM EDWARD K
IPC: A61N1/372
Filed: 1996-01-16
Abstract: An apparatus for transcutaneously transmitting a power signal to, and communicating first and second information signals with, an implantable device. The apparatus can include an external unit having first power means for generating the power signal; first signalling means for generating the first information signal; first receiving means for receiving the second information signal; and first coupling means for independently coupling the power signal and said first information signal. The apparatus can also include an internal unit having second power means for receiving the power signal; second signalling means for generating the second information signal; second receiving means for receiving the first information signal; and second coupling means for independently coupling the power signal and the second information signal. The first power means transmits the power signal at a power frequency, and the first signalling means can transmit the first information signal at a frequency greater than the power frequency. The first power means may also include a power supply. The second signalling means, too, may transmit the second information signal at a frequency greater than the power frequency. The external unit can include a power converter for converting a power input signal at a first preselected frequency to a power signal at the power frequency; an external coupler for transmitting the power signal, and for communicating the first and second information signals; an external signal conditioner for symmetrically transceiving the first and second information signals; and an external data controller for symmetrically controlling the first and second information signals. The internal unit can include an internal coupler for receiving the power signal and for communicating the first and second information signals; a voltage regulator for converting the first power signal into said second power signal which is provided to the implantable device; an internal signal conditioner for symmetrically transceiving the first and second information signals; and an internal data controller symmetrically controlling the first and second information signals. Symmetrically controlling includes ASK modulation of a data signal upon an RF carrier signal of a preselected carrier frequency, which is presently preferred to be about 8 megaHertz (MHz). The external and internal couplers each can include a primary and secondary tuned circuit, respectively. Each tuned circuit has a resonant frequency which can be, for example, about 160 kiloHertz (kHz). In addition, the first and second signal conditioners can include a first and second frequency-selective filter, respectively. Each frequency-selective filter can have cutoff frequencies of between about 7.9 MHz and 8.1 MHz, with a central frequency of about 8 MHz.

Inventor: KAMMERAAD JAMES A
IPC: F01L3/08
Filed: 1993-03-17
Abstract: A thin-walled valve guide insert for lining and relining a valve guide of an internal combustion engine includes opposing ends each having a tapered insertion section thereon.  The tapered insertion section defines a reduced outer diameter to facilitate installing the insert into a valve guide bore have a nonchamfered opening, and further defines a reduced inner diameter so that the insert has a substantially continuous wall thickness throughout its length and thus maintains the structural integrity of the insert from end to end.  In the preferred embodiment, the valve guide insert is made of a phosphor bronze material of about .018 inch thickness or less, and includes a lengthwise slit therein.  The insert is sprung open longitudinally along the slit and must be radially compressed so that the insert defines a sufficiently small outer diameter so that it can be axially installed in a press-fit condition into the valve guide bore of the engine.  Both ends of the insert are formed with the tapered insertion section so that the insert can be positioned without regard to which end is directed toward the valve guide.  Also disclosed is a tool for inserting the insert into the guide valve, the tool including an outwardly tapered junction adapted to spread one of the tapered insertion sections of the insert into longitudinal alignment with the insert to reduce the tendency to crush same from end forces exerted on the insert while installing the insert into the valve guide.  Still further a process is disclosed for forming the guide valve insert with ends having tapered insertion sections thereon.

Title: A data acquisition system and method
Inventor: CRANFORD JOHN C
IPC: G01S15/89
Filed: 1995-04-14
Abstract: A ranging and data taking system, useful as an acoustic sediment classification system. The system launches acoustic pulses into a water column above a sediment bed of interest (seafloor, riverbed, etc.) and records echoes from the pulses. The recorded echoes are transmitted to a processor (40) which uses the echoes to classify the sediment. Disclosed between the hardware for data acquisition and the processor (40) is S-RAM or static read only memory (36). This decouples data acquisition and data processing, which increases the speed of the system sufficiently that the system can display processed data, such as sediment contour plots, in virtual real time.
