  • Patent number: 4393375
    Abstract: An improved operator controlled system for a copying machine to minimize user error and to provide a compact control console. An information display member is capable of sequentially displaying an identification of discrete operating features, such as number of copies, etc. A memory is capable of storing a predetermined set of first command signals for each discrete operating feature. A common set of control members permits the user to selectively generate second input command signals relative to any specific operating feature. These same control members are capable of inputing signals for a number of different operating features. The copying machine is capable of discriminating between the input command signals and the particular operating feature. The resulting operation of the copying machine would be in accordance with the predetermined standard set of machine functions or any combination thereof of operator inputed command functions.

  • Patent number: 4388620
    Abstract: A method and apparatus provides for the generation of a number of elliptical images on a raster scan video display screen by storing information indicative of a predetermined model image, and for each elliptical image to be displayed, storing data indicative of the vertical and horizontal eccentricity of each image, and its display location. During display time, the vertical eccentricity, horizontal eccentricity, and display location binary information for each elliptical is accessed and used to sequentially read selected portions of the model image information to produce therefrom address signals indicative of the location of individual horizontal display elements that make up the desired elliptical image. The address signals are applied to a random access memory to store marker information indicative of the elliptical image at memory locations corresponding to the position on the display screen that the image will take.

  • Patent number: 4374380
    Abstract: To provide a visible output indication, for example by an indicator light on a controller supervisory panel of the vehicle, of proper functioning of the voltage regulator power transistor, monitoring circuits are provided which sense the electrical condition of current flow through or the voltage condition of the field winding or output bus respectively by including a light emitting diode (LED) in an indicator circuit, for example by connecting it in series to the coupling resistor. In one form, a Zener diode Z (FIG. 1) is connected across the output bus with the LED in series, so that the LED will light if the output bus reaches a voltage which might damage the battery, for example due to short circuit or alloying-through of the output transistor T of the voltage regulator; in another form, an LED which preferably is green, LDg (FIG.

  • Patent number: 4369440
    Abstract: A device is provided for the rapid and easy introduction of data into an apparatus, e.g., for setting a digital watch. A binary decision device continuously tests the state of a plurality of finger responsive sensors A, B, C and D and produces control signals for a operational unit. The operational unit comprises an up-down counter which can be incremented or decremented by signal F1 to F8 at different frequencies. An inertia effect is produced by maintaining counting of the up-down counter between two successive actuations of the sensors. Touching sensor B or C stops the counter. Sweeping A, B, C, D speeds the incrementing rate (up to a top rate) or slows the decrementing rate while sweeping D, C, B, A acts conversely. Touching A and D alone, respectively, single-steps the counter down and up. The amount by which the rate is speeded or slowed can be made to depend on the speed of sweeping the sensors as well as the number of times they are swept.

  • Patent number: 4368463
    Abstract: A method and apparatus are provided for classifying areas on a raster-type display unit. The problem is to identify areas defined by a closed boundary--e.g. for filling in such areas. Boundary data are entered into a first "polygon" store which has a plurality of memory locations each corresponding to a respective dot position of the display field, and at least one seed point is identified. Each dot position is then examined to see whether there exists a connected path, not including a boundary position, from it to a seed point, and if there is, this fact is recorded. The criterion for deciding whether or not a path is connected depends on the definition of what constitutes a closed boundary.

  • Patent number: 4365240
    Abstract: An attitude change alarm for securing articles from theft or other undesired movement. The alarm includes a case having a wall which defines a hollow interior. Resistive elements are maintained within the wall in spaced relationship with each other and in common communication with an electrically conductive surface on the outside of the wall. An electrically conductive member is fixedly maintained in the hollow interior in constant contacting engagement with a conductive fluid which makes selective engagement with certain of the resistive elements. When the alarm is moved, a current is transmitted from the conductive coating through the resistive elements, fluid, and member, and is passed to a transformer which gates an SCR into conduction, activating the alarm. Various geometrical configurations of the attitude change alarm are presented, each having specific attributes associated therewith.

  • Patent number: 4363029
    Abstract: A proximity switch in which the electronic characteristics of a liquid crystal display are monitored relative to a reference liquid crystal display to determine when an operator has come into proximity thereto. A controller monitors the display elements, liquid crystal displays, respective capacitances or inductance and when an operator comes into proximity to an electrode in the display element, the controller senses this proximity due to the change in capacitance or inductance of the element. This sensing allows the controller to recognize when a change of state is desired by the operator. The use of the reference element allows the controller to respond only to operator proximity and not to noise caused by changes in the environment, such as temperature.

  • Patent number: 4363031
    Abstract: A wireless smoke alarm system in which each detector includes a local smoke detector and an alarm. These are coupled to a transmitter and a receiver. The transmitter and receiver are within range of similar units so that an alarm sounded by one unit causes those within range to sound their respective alarms. In sounding their respective alarms, the local units also cause their transmitters to transmit alarm signals thereby overlapping and reinforcing the first unit. A master control is coupled between the alarm detection and local alarm portion and the transceiver to disconnect the unit when the alarm is ended and to transmit a signal to other units, causing each to discontinue their respective alarms.

  • Patent number: 4363030
    Abstract: In an instrument system consisting of a transmitter in one location and a receiver in another location connected by a transmission medium, fail-safe operation is obtained by restricting the output of the transmitter to well-defined levels and interpreting any substantial departure of the received signal from these well-defined levels as a failure. When a failure is detected, alarms or other equipment may be activated, including a control circuit which causes replacement of the defective transmitter or transmission medium, thereby restoring the system to service. An embodiment wherein the transmitter is an admittance-responsive transmitter in a two-wire current loop for monitoring the condition of materials is described.
