Title: Multiple frequency impedance measurement for physiological monitoring of the condition of a patient's body tissue
Inventor: HUDRLIK TERRENCE R
IPC: A61B5/053
Filed: 1993-03-10
Abstract: A physiological monitoring system for monitoring the condition of a patient's body tissue. The device includes electrodes for contacting the tissue to be monitored, circuitry for generating electrical signals at at least two frequencies for application to the tissue and circuitry for monitoring the impedance of the tissue, at the frequencies applied. The device includes in addition apparatus for detecting changes in the relationship of the measured impedances at the frequencies applied, and for processing the detected changes in impedance relationship to provide an indication of the condition of the tissue. The monitoring apparatus may be practiced in the context of an implantable stimulator, such as a cardiac pacemaker, in which the pulse frequency is varied as a function of the detected condition of the tissue.

Inventor: BLANCHARD PIERRE
IPC: B62K19/28
Filed: 1994-04-13
Abstract: Dans un joint servant à obtenir un mouvement de rotation autour d'un axe, on sait que les collets utilisés on souvent tendance à se déserrer où à ne pas épouser parfaitement la forme de l'axe. Cette tolérance crée un jeu entre la partie fixe (l'axe) et la partie mobile (le joint) et entraîne une imprécision du mouvement et une usure prématurée des pièces en mouvement. Le joint perds alors beaucoup de sa performance et sa raison d'être qui est d'établir un lien étanche et précis entre une pièce fixe et une autre mobile. Dans la présente invention, le joint peu s'ajuster de façon micrométrique autour de son axe tout en maintenant une tension constante autour de celui-ci. Le dispositif d'ajustement sert à la fois à adapter parfaitement le diamètre du joint à la forme arrondie de l'axe ou du coussinet sur lequel il rotationne et à créer une tension qui empêchera le joint de se déserrer. A plus long terme, le joint peu se resserrer à demande pour compenser le jeu crée par l'usure inévitable d'un système en mouvement.

Title: Audio signal transmitting apparatus and the method thereof
Inventor: ICHIMURA GEN
IPC: H03M3/04
Filed: 1994-06-27
Abstract: A recording and/or reproducing apparatus for recording and/or reproducing digital audio signal on a recording medium such as a magnetic tape, which includes a recording and/or reproducing unit, an analog-to-digital convertor, a decimation filter, and noise shaper. The recording and/or reproducing unit records and/or reproduces signal on a recording medium at a speed double relative moving speed of a head and the recording medium at least. The analog-to-digital convertor converts input analog audio signal into digital signal with a sampling frequency which is above the audio frequency band, and sufficiently higher than the maximum frequency capable of recording by the recording and/or reproducing unit. The decimation filter reduces the sampling frequency of the digital signal output from the analog-to-digital convertor, and converts it into digital signal of m-bit (m > n). The noise shaper converts the digital signal from the decimation filter from m-bit to n-bit, and then in requantizing, shapes noise so as to suppress within the audio frequency band, and supplies it to the recording and/or reproducing unit.

Title: Filter with molded end cap and media spacer
Inventor: KELLER DENNIS B
IPC: B01D29/11
Filed: 1995-11-17
Abstract: A filter of the type used to filter gases or liquids has molded plastic end capson each end of the filter element with the ends of the filter element molded into the end caps. To prevent the end of the filter element from being exposed through the exterior surface of one of the end caps, a spacer is located between the end of the filter element and the exterior surface of the end cap. The spacer allows the plastic material of the end cap to permeate the spacer to form a thin layer of plastic on the end of the filter element. This prevents thin spots in the end cap which could result in leakage through the end cap.
