  • Patent number: 4933846
    Abstract: A network communications adapter interconnects a plurality of digital computing resources for mutual data exchange in which a high performance, large capacity common memory is provided with a pair of external buses which allows multiple processors to store information in and read information from the common memory. The common memory is configured into two banks, each bank operating independently and concurrently under control of bus switching logic with separate address, control and data buses. The common memory typically provides 400 megabits per second of bandwidth to the multiple attached thirty-two and sixteen bit processors which may be coupled either to both buses simultaneously or individually to the two buses. The bus switching logic then allocates all of the available bandwidth to the individual processors coupled to the buses based upon a predetermined profile established at the time of system installation. Also included in the bus switch logic is circuitry for broadcasting a processor I.D.

  • Patent number: 4930519
    Abstract: A method of graphically displaying cardiopulmonary function data by providing a plurality of axes radially projecting from a common point of origin, there being one such axis for each cardiopulmonary parameter to be plotted, each axis having scale markings thereon whereby the normal value for each parameter will lie an equal distance from said point of origin, and straight line segments connected between said normal values on adjacent axes will form a generally regular polygon. The cardiopulmonary function data to be displayed are then plotted on the same appropriate axis and to the same scale such that deviations of any such data from normal will result in an irregular polygon when the segments are joined between plotted values on adjacent axis. Deviations of the irregular polygon from the regular polygon thus provides a clinician with a readily visible display of possible cardiopulmonary disfunction.

  • Patent number: 4896559
    Abstract: A mechanism for adjusting vehicle handlebars includes a lower hub intergral with a vehicle steering column, and an upper hub formed as an integral part of the handlebars. Two opposed diamond-shaped plates rotationally receive both hubs. Two locking gears, one integral with each hub, form various interlocking engagement with one of the plates, corresponding to different handlebar position settings. A release lever, pivotally attached to one of the plates, is pivotable to urge the plates away from one another to release the locking engagment of the gears and projection groove, enabling movement of the handlebars to different settings. A spring loaded detent prevents inadvertent release of the mechanism, and must be moved against the force of a torsion spring prior to the pivoting of the release lever.

  • Patent number: 4884611
    Abstract: A machine for facilitating the removal and replacement of tire casings from and on the rims of vehicle wheels. The machine incorporates a first hydraulically actuated tool for breaking the bead of the tire casing to be removed free from the rim. Subsequently, the wheel is placed upon a motor driven turntable and clamped in place relative thereto by a second hydraulically actuated mechanism. Once the wheel and tire are clamped in place, a tool support head is brought into play for supporting a tire iron, the end of which is introduced between the rim and the tire's bead. Now, when a hydraulic motor is actuated, the turntable with the wheel and tire clamp thereto is rotated causing the tire bead on one side of the tire to be lifted free of the rim. The process is repeated for the tire bead surrounding the opposite side wall, at which point the old tire has been totally removed from the rim.

  • Patent number: 4865036
    Abstract: A cardiac stimulator apparatus for effecting cardioversion or defibrillation in the event of pathologic tachycardia or ventricular fibrillation in which the rate of heart depolarization signals is compared to a predetermined heart rate value indicative of the onset of tachycardia while, simultaneously, the heart's pre-ejection period is monitored to sense whether an increase in heart rate above the predetermined value is accompanied by a decrease in the pre-ejection period. If not, a pathologic rather than a physiologic episode is diagnosed and a cardioversion pulse protocol is initiated. By also monitoring the mechanical pulse of the heart, if an inordinately high heart rate is accompanied by a low or non-existing mechanical pulse, ventricular fibrillation is diagnosed and the cardioverter is triggered to shock the heart back into sinus rhythm. If the mechanical pulse rate tracks the electrical rate of depolarization, tachyarrythmia is confirmed.

  • Patent number: 4862225
    Abstract: A fusing system for a xerographic printer in which the energy from a plurality of flash lamps is used to melt and fuse toner particles to paper sheets as said sheets travel through the fusing station. Each flash lamp has an associated storage capacitor and a charging circuit for that capacitor which is operative to develop a charge on its associated storage capacitor depending upon the length dimension of the paper sheets flowing through the system. Moreover, the capacitor charging circuits are rendered operative in a predetermined serial order so as not to unduly load down the alternating current source for the system. A lamp triggering circuit synchronized with the zero-crossings of the alternating current supply voltage provides the ignition potential for the flash lamps such that firing takes place at a time when the supply voltage is at a minimum.
