Abstract: Abstract VDD LOAD DUMP PROTECTION CIRCUIT The present invention provides power supply load dump protection circuitry for insuring that supply voltages that are applied to the supply pad of a low current logic circuit and which exceed a preselected voltage level are prevented from damaging the logic circuit and also from appearing at an output of the logic circuit.  Three circuit areas are protected.  An integrated 5V regulated supply circuit is protected by connecting the supply pad to a polysilicon resistor in series with the source of the p-channel MOS output pull up transistor of the regulator circuit, the drain of the driver being connected to the 5V regulated supply pad.  16V low current logic circuits associated with the input pads, output pads and the 5V regulator are protected by connecting the supply pad to a large value polysilicon resistor in series with the power supply pads of these circuits.  16V high current output signal circuits are protected by connecting the supply pad to the source of the p-channel MOS output pull up transistor of the output circuit, with its drain being connected to the output pad.  Each of the p-channel MOS transistors has its gate connected to a detection circuit which, upon detection of load dump transients, turns them off.  All of the above-described transistors and resistors, are designed to withstand maximum load dump transients.

Title: Basic pulse frame and method for a digital signal multiplex hierarchy
Inventor: POSPISCHIL REGINHARD
IPC: H04J3/07
Filed: 1988-12-14
Granted: 1992-07-07
Abstract: Abstract of the Disclosure A basic pulse frame is disclosed that is employable in a synchronous network for digital signals of both the CEPT hierarchy as well as of the US hierarchy while maintaining maximum transmission capacity.  The synchronous payload envelope (SPE) of the basic pulse frame is composed of 9 rows (Z) and 264 columns (Sp).  A configuration that is optimum for signals of the CEPT hierarchy and a configuration that is optimum for signals of the US hierarchy is achieved, each of which also allow a transmission of sufficient signals of the other type.  The configuration for preferably CEPT signals comprises 16 main blocks (HBla-HBl6a) and two auxiliary blocks (ZBla, ZB2a).          Both serve for the optional occupation with auxiliary signals; the second auxiliary block (ZB2a) also additionally serves for optional occupation with useful data signals. 204 bit/kbit/s CEPT signals transmitted in the synchronous payload envelope (SPEla) can be completely inserted into 34,368 kbit/s signals of the higher CEPT hierarchy level {and] 1544 kbit/s US signals transmitted in the synchronous payload envelope (SPEla) can be inserted with minimal loss of transmission capacity into 34,368 kbit/s signals of the higher CEPT hierarchy level that can follow a common 139,264 kbit/s hierarchy level.  The configuration for preferably US signals contains 21 main blocks and 3 or 4 auxiliary blocks.          The basic pulse frame is suitable for a world-wide digital signal multiplex hierarchy for a synchronous network.

Abstract: INFLATABLE BUOYANCY BELT                  ABSTRACT OF THE DISCLOSURE          An inflatable buoyancy belt is disclosed comprised of a segment of expandable tubing closed at either end with flattened plugs, carrying fittings enabling adjustable securement of a nonstretchable belt, the tubing segment and connected belt each of a length to extend approximately half way around a wearer's trunk.  A gas cartridge holder-inflator fitting is incorporated into one of the end plugs, the gas cartridge releasing a volume of gas only partially inflating the tubing segment, causing a localized bubble to be formed, acting as a buoyancy chamber confined to one side of the wearer's body.  The lengthening of the tubing segment at inflation offsets the tightening effect  of the bubble to insure a sufficiently loose fit to the wearer so as to allow ready adjustment of the position of the bubble to the wearer's upper trunk.

Granted: 1993-01-12
Abstract: ABSTRACT OF THE DISCLOSURE     A system is described for sensing the relative angular orientation of two relatively movable joint segments of a living body joined together at a joint. The system comprises at least two links coupled together about a pivot axis so that the links are pivotable relative to one another about the axis so as to define a variable mechanical angle between the links about the axis.  The two links are secured respectively to the joint segments so that the links pivot about the pivot axis when the joint segments pivot about said joint.  A Hall effect sensor is used to accurate sense the mechanical angle.  The mechanical angle sensed by the sensor is then correlated with the actual angle made by the joint segments.  The arrangement is used with each finger and thumb joint of the hand to provide data representative of finger and thumb orientations of a hand.
