Abstract: The one-shot multivibrator disclosed herein provides precise timing at high speed by controlling the charging and discharging of a timing capacitor over a voltage swing which is compensated so as to be essentially independent of any temperature-dependent offset voltages such as base-emitter drops.

Abstract: A device for storing rectangular sheets to be fed into a sheet conveying path in an image forming apparatus comprises a sheet tray for stacking thereon the rectangular sheets. The movable tray having a first and second sides used for longitudinal and lateral feeds of a sheet with respect to the sheet conveying path, respectively, is movably supported on a base member for the movement between a first and second positions at which the first and second sides of the sheet tray are located at a constant position for the longitudinal and lateral feeds of the sheet, respectively. A connecting member is joined to the sheet tray at a position near the intersection of the first and second sides thereof. A reciprocating device is provided for causing the sheet tray to be moved between the first and second positions by reciprocating the connecting member in a direction transverse to the feeding direction of the sheet with respect to the sheet conveying path.

Abstract: A method and device for providing a timing signal to a medical device in response to light emitting indicators on a cardiac pacer. The device is optically coupled to the light emitting indicators, but is electrically isolated from the cardiac pacer. A timing signal is generated in response to activation of the light emitting indicators which indicate that an R wave was sensed or a ventricular pace signal was sent.

Abstract: A digitizing tablet is disclosed in which two sets of circuitous conductive lines form grids each connected at one end to a surrounding conductive loop. All outputs are measured from the conductive loop as a multiplexor sequentially grounds the grids one at a time. The outputs are fed through linear spatial filters which are used to produce intermediate signals which are in turn combined to arrive at raw position signals for a position indicating coil located over the work surface. Separate sets of linear spatial filters may be used to produce two raw position signals differently responsive to tilt which can then be combined to arrive at a true position signal insensitive to tilt.

Abstract: A combination catheter connector and clamp provided with an interlocking hook and post for locking two connector parts together. A manifold separates the lumens of a multilumen catheter into separate arms which can be closed or opened by a pushbutton clamp. A silicone block is used between the engagement portions of the connector parts.

Abstract: A pump housing which contains a plurality of linear peristaltic pumps and receives a fluid source cartridge. The cartridge is provided with retaining knobs for engaging retaining holes in the front end of the pump housing. A cartridge further contains a tab at its rear end for engaging a locking mechanism in the pump housing. The cartridge contains linear fluid conduits which align with the linear peristaltic pumps for pumping fluid from the fluid source pouches within the cartridge. Each pump is individually controlled by a programmable controller within the pump.

Abstract: An apparatus for delivering product into a feed tube including a tip over drum which has a tray supported between two side walls. The tray has a convex hump near the axis of rotation for dividing product fed by a gravitational feed into two portions.

Abstract: This invention, as herein illustrated, is for delivering caps in succession, one at a time, to a distributor for application to the tops of containers. There is an end wall at the bottom of a chute against which the bottom cap in the pick-off position abuts. The force against the bottom cap is reduced by providing a bent portion near the lower end of the chute.

Abstract: In the voltage controlled oscillator disclosed herein, the charging and discharging of a timing capacitor is controlled by a differential input comparator which establishes precisely defined switching thresholds. The comparator input circuit is provided with an internally generated, temperature compensated input bias current which substantially relieves the timing components from providing bias current, thereby facilitating a wide range of operation.

Abstract: A circuit for decreasing the minimum duty ratio of a switching element in a power converter in response to a signal indicating that sensed current exceeds a second threshold. The circuit turns off the switching element when the sensed current exceeds a first threshold. The minimum duty ratio may be decreased, for example by increasing the period of the switching element or by increasing the "off" time of the switching element. The circuit protects against current runaway.

Abstract: A license storage key is provided for securely storing information regarding which licenses have been purchased for a network of computers, how many of each license have been purhcased, and any time limits associated with each license. An application program to be run on a computer must be assigned a license in the license storage key associated with the computer before it will be permitted to run. If a license cannot be found on the local key, a license may be found on another key in the network of computers and transferred to the local key so that the application program may be run in this case, when the license is released. The license storage key contains a hardware clock which is used to determine whether a license has expired.

Abstract: A system for simultaneously using a video signal to provide a video picture and computer data. At the transmitting end, a video signal is digitized and then modified by substituting digital signals representative of computer data for those representative of video pixels. The modified signal is reconverted to an analog signal and transmitted to a receiver. The receiver displays the video picture corresponding to the modified signal and extracts the computer data so that they may be provided to the computer. The computer can thus be controlled by the computer data as the video picture is being displayed.

Abstract: A supply bias circuit in which supply current is provided through a resistor coupled to a timing circuit such that this resistor acts as a low pass filter in conjunction with the timing capacitor. Supply current is passed from the timing current through a second resistor and into logic circuitry. The logic circuitry is further connected to the timing circuitry so that it receives extra current each time the capacitor discharges.

Abstract: An initialization or synchronization method in which at least a predetermined number of synchronization messages are sent out over a two-way communication line. The receipt of a synchronization message is awaited before terminating the transmission of synchronization message. After the transmission of synchronization messages has been terminated the receipt of a non-synchronization message will complete the synchronization process. However, certain conditions may cause synchronization to be restarted such as a predetermined number of consecutive error messages, failure to receive any message in a predetermined number of clock signals, receiving more than a predetermined number of synchronization signals, or a reset command.

Abstract: A computing system is disclosed which uses a system busy signal on its system bus to help control access to said bus. One or more requesters can generate a request signal when the system busy signal is not asserted. System busy is asserted along with the request signal(s) and remains asserted until all requesters which generated a request signal have gained access to the bus in order of priority. A freeze signal is generated on the system bus during the address phase of an instruction and a wait signal is generated during each data transfer in the data phase of an instruction. The freeze signal may be generated by a memory control unit, a memory module or a requester.
