  • Patent number: 4975945
    Abstract: In cooperation with a public telephone network, an automated call processing system incorporates an audio response unit and a computer for effectively relaying calls to a manually attended terminal. Individual calls are assigned unique call reference numbers which are stored along with pertinent information of the call. If a call relay is commanded, the computer actuates a PBX to establish a secondary connection through the telephone network to an attended CRT terminal. Using the secondary connection, the operator at the terminal is given the reference number which addresses the call data fetching it to the terminal for use by the operator. As a final operation, the secondary communication path is bridged placing the operator at the attended terminal in communication with a caller through the original connection established through the audio response unit.

  • Patent number: 4974155
    Abstract: In a pipeline computer, current instructions executed in sequence are monitored for conditional and unconditional branch commands, as well as the readiness of condition codes, the meeting of branch conditions and split commands. A branch command initiates an interval of delay which affords prefetching target instructions while using pipeline contents to prevent a pipeline break and avoid lost time. Detection of a branch command actuates a register to store a sequence of target instructions. Unless a branch command is conditional, subsequent detection (delayed) of a split command shifts the stored target instructions into operation as the current instructions. For a conditional branch command, a jump or split to the target instructions is performed only if the condition is met. Otherwise the current instruction sequence is restored pending another branch command.

  • Patent number: 4970500
    Abstract: A display system is disclosed utilizing a cathode ray display device utilizing three electron beams which are directed through a shadow mask to excite three-color phosphor dots, and which is incorporated in a system to alternately provide raster scan display signals and calligraphic display signals to obtain the benefits of both raster scan and calligraphic displays (dot or line drawings). A deflection unit is disclosed with the X and Y deflection coils each driven by two pairs of transistor circuits. The transistor circuits are controlled so that alternatively one transistor in each set passes current to provide bi-directional currents at desired levels to obtain specific beam displacement. A resistive element between individual deflection coils provides an indication of deflection current, which indication is processed by a differential amplifier to indicate displacement. In accordance with the instant position of the beam, a convergence unit is controlled to reflect spherical considerations.

  • Patent number: 4968124
    Abstract: A vehicle viewing system for use on vehicles to enhance the vehicles' safe operation by minimizing blind spots. The system has an objective assembly mountable on the vehicle with its field of view substantially encompassing a blind spot. The images within the field of view are carried from the objective assembly to a viewer assembly via an image relay system. The image relay system may be a conventional fiber optic cable or a periscope assembly mounted between two fiber optic cables to extend the image transmission. The periscope assembly utilizes a lens assembly to relay images. The viewer assembly is mountable in an easy-to-see location on the vehicle suitable for viewing by the vehicle operator. The objective assembly has a lens system to enable the system to present continuous color images for viewing.

  • Patent number: 4963702
    Abstract: A digitizer pad apparatus includes at least one digitizer ply where each digitizer ply has a first and a second resistor strip, each with a resistance gradient along its length, oriented in spaced apart relationship. A plurality of conductor traces are interconnected along the length of each resistor strip to extend toward and be interleaved between each other to define a sensor pad region. Each sensor pad region defines a dimensional direction. A shunt ply is positioned to face the sensor pad region in normally non-conducting relationship so that when a selected area is pressed into contact with the conductor traces, conduction between adjacent conductor traces via the shunt ply will occur in the selected contact area. The selected contact area has a first edge and a second edge opposite the first edge along the defined dimensional direction.

  • Patent number: 4954819
    Abstract: For use in a computer graphics apparatus, a data management system drives a multiple-window dynamic display. The display is formed by areas, e.g. pixels, and windows are variously defined in a display by assigning window codes to groups of areas. Image data for each area provided from a picture system is selectively registered in an image frame buffer in accordance with the defined windows. Valid data binary signals, designating currently valid image data in the image frame buffer are registered in three valid data buffers. The image data for each area is provided for a display from the selectively registered signals in the image frame buffer under control of the window codes and the valid data binary signals. Techniques are thus available for rapidly swapping portions of the frame buffer and selectively clearing and loading the image frame buffer. Areas not specified by signals from the image frame buffer are treated as background and driven with an appropriate display.

  • Patent number: 4952152
    Abstract: To accommodate computer graphics delays, the future position and orientation of a simulated vehicle are predicted in an operating sequence by separate coordinated models that are fed data signals indicating the operator's control actions. The control actions are extrapolated to provide further data signals. A suspension model and a nonlinear chassis model operate sequentially with a road model to provide one reference-state input to a prediction model. Other inputs to the prediction model are from the drive train and steering extrapolation units controlled by driver inputs.

  • Patent number: 4949500
    Abstract: An insect or vermin trap having a main housing and high voltage generating means within the housing. The generating means generates a voltage of sufficient magnitude for exterminating insects, vermin or the like entering the trap. One or more entries into the main housing when the electrodes are in that housing or into the separate housing if the electrodes are in a separate housing the the entries enabling insects or vermin to enter the trap. Two spaced electrodes either within the main housing or separate housing supplied with the voltage generated by the generating means for exterminating insects or the like which bridge the space between the electrodes. Control means is present for providing controlled alternation between an on period for which the electrodes are supplied with the high voltage and an off period for which the electrodes are not supplied with the voltage.

  • Patent number: 4949192
    Abstract: A system for use with a mag-stripe card for transducing signals and performing predetermined transaction processing to record fresh data on the card. A closed-end slot is defined for guiding the card in manual motion. Offset record (broad path) and read (narrow path) transducers are mounted in a relationship to afford increased tolerances. Optical sensors manifest card positions as data for a processor to control and sequence proper operation. The processor also receives confirmatory read signals to verify proper recording on a card.

  • Patent number: RE33406
    Abstract: A swimsuit for ladies designed with an inner figure-controlling liner garment and an outer single ply bathing garment. The inner and outer garments, formed of elastic materials, are sewn separately along their common perimeters. The inner garment is smaller than the outer garment with greater lateral than vertical stretch for freedom of movement. Secured to the upper edge of the inner liner is a set of arcuate stays which are attached at their ends only to the inseam of the outer garment. The stays support the breasts and lift them upwardly and outwardly against the outer garment for an enhanced but natural appearance.
