Abstract: A sonar transducer network for observing a seabed includes a controller. A first transducer assembly includes a first acoustic transducer to convert a first ping to a first electrical signal; and a first transducer processor to receive a first electrical signal from the first acoustic transducer to generate the first transducer data. At least one second transducer assembly is spaced apart from the first transducer assembly. The second transducer assembly includes a second acoustic transducer to convert a second ping to a second electrical signal. The second transducer processor receives the second electrical signal from the second acoustical transducer to generate second transducer data. A network bus communicates first transducer data and second transducer data with the controller.

Abstract: Apparatus for transferring electrical energy to and from living tissue comprises a glove of thin, flexible elastomeric material, which carries electrodes, electrically connected to a connector disposed at the cuff of the glove. The connector permits the electrodes to be electrically connected to a source of electrical energy or to a load, so that electrical energy may be applied to or drawn from living tissue.

Abstract: A stimulator for penile erection comprises a body member which may be inserted into the rectum of a user, the body member being so shaped as to closely conform to the topological configuration of the rectum from the anal area to a site adjacent to the prostate gland. Within the body member is electrical circuitry for generating a neutrally stimulating electrical signal. Electrodes, placed at particular locations on the surface of the body member, apply the signal to the user. At least one of the electrodes closely contacts the prostate gland when the body member is operatively disposed, at a region or spot on the prostate gland previously determined to be sensitive to electrical stimulation.

Abstract: A method and apparatus for noninvasive, quantitative measurement of blood flow rate in a blood vessel includes a transducer array placed on the skin surface above the vessel of interest. The array is formed of transmitting and receiving elements for transmitting and receiving beams of ultrasonic energy. Pulsed ultrasonic energy is transmitted by the array into the body tissue and intercepts the flow in the blood vessel at a slant angle which is determined by electronically steering the transmitted beam, causing it to rotate through a predetermined angular change. The resulting Doppler frequency shifts of the received ultrasonic energy backscattered by moving particles of the blood flow associated with the angular orientation of the transmitted beam can then be measured. Through electronic range gating techniques, the Doppler frequency shifts at the determined slant angle are measured at various depths or ranges below the skin at different positions across the vessel cross-section.
