  • Patent number: 6201951
    Abstract: The control panel of a telephone set is detachable from a base station portion of the set. The control panel and base station can communicate mutually cordlessly, or the control panel can be connected for communication independent of the cordless facility. The control panel includes an interactive display panel with a touch screen and a graphic tablet, and control electronics for the display panel. Telephone numbers, spoken and written messages can be transmitted via the touch screen with a finger, or via the graphic tablet with a special pen.

  • Patent number: 5960366
    Abstract: Known is a wrist-watch telephone with an LCD display, and further a portable wireless data collection terminal. Such devices do not take into account all human factors that are to be considered for getting a true multimedia miniature and portable wireless two-way telephone. A wrist-watch wireless telephone is proposed having an interactive display screen as a graphical interface, preferably pen-activated. For still more multimedia like operation, screen functions of the wrist-watch wireless telephone are controlled by further actuators such as a watch button.

  • Patent number: 5959627
    Abstract: For visual user-presentation of a compilation system for multiple audio and/or visual items each item is associated with various attributes that each express a category, a value, or a label, and through selection among the items produces a compiled subset of items. In particular, the presentation is multidimensional in parallel over the various attributes, that each allow said selection therein on a uniform level. Through each selection presentation of items that discord with the actual selection is suppressed, so that each selection diminishes the multidimensionality of said presentation. Furthermore, a selection of effectivity controls is displayed.

  • Patent number: 5541372
    Abstract: A touch screen device includes a panel; a sensor coupled to the panel for detection of a force applied to the panel and a data processor coupled to the sensor for processing data transmitted by the sensor upon detection of the force. The sensor is provided to be co-deformable with the panel for detecting a deformation of the panel itself as a result of the force being applied. This avoids the use of a rigid frame as in conventional devices, saving weight, costs and components, and reducing manufacturing problems. The sensor means may comprise strain gauges that are physically integrated with the panel. Combined with a display such device presents a minimum parallax.

  • Patent number: 5402151
    Abstract: A data processing system includes a multipurpose data input device formed by a touch screen and a digitizing tablet integrated with one another, which are activatable independently of each other by proper stimuli. The touch screen and the digitizing tablet each comprise a respective sensing means to sense the proper stimuli. The respective sensing means comprise respective components for producing respective signals representative of the proper stimuli, the respective components being physically and functionally distinct from one another. The input device is integrated with a flat panel display in order to establish a visual feedback to the user or to present information pertaining to the entered data after processing. The flat panel display, touch screen and digitizing tablet take a variety of forms and a variety of techniques are utilized to determine which of the touch screen and digitizing tablet is activated at any time.

  • Patent number: 5146248
    Abstract: A light valve projection system includes an illumination system having a light collector in the form of a non-imaging reflector with a rectangular input aperture and a rectangular output aperture. A two dimensional light source at the input aperture illuminates the output aperture substantially uniformly.

  • Patent number: 5117152
    Abstract: A monochrome cathode ray tube including a magnetic focusing device provided with means for generating a static magnetic focusing field. These means surround the neck of the cathode ray tube without contacting this neck, and a system of correction coils for generating an additional focusing field and 2-, 4- and/or 6-pole fields is provided coaxially between these means and the neck of the tube.

  • Patent number: 4922240
    Abstract: In a matrix display device, such as an LCD-TV, supply of data signals to each one of an array of display elements is controlled by respective switching means in response to applied switching signals. Novel addressing circuitry is provided to achieve redundancy and avoid improper charge levels on non-selected switching means.

  • Patent number: 4835602
    Abstract: A projection television convergence method and apparatus allow rapid and simple correction of low-order misconvergence and misgeometry problems. A hybrid system employs digital programmable attenuators and a digital control system, making it possible to eliminate misconvergence and misgeometry using simple local adjustment on a limited number (e.g., 9) of locations in the picture. The values of the coefficients in the correction waveforms, which are represented by the settings on a number of programmable attenuators, are determined by simultaneously solving the convergence governing equations, and are stored in memory. Thus, the prior art tedious individual adjustment of typically more than 30 potentiometers, each with global effects, by a factory worker, service-engineer or the consumer is obviated. An alternate embodiment includes a simple black and white camera to eliminate the human adjuster.

  • Patent number: 4807014
    Abstract: A projection color television system having an improved resolution and luminance comprises red, green and blue color emitting tubes, the electron beams of which are focused onto their respective screens. In order to compensate for the strong saturation of the blue phosphor, and simultaneously to take advantage of the relatively fast decay of this phosphor, the blue color emitting tube is a single gun, multispot display tube. The increase in light output obtainable from the blue color emitting tube is matched by providing interference filters in the red and green color emitting display tubes and optionally in all three red, green and blue emitting tubes.

  • Patent number: 4775817
    Abstract: The invention relates to a display tube which is cooled by a flow of a translucent cooling liquid through a sealed space adjacent the display window, stimulated by a fluid-driven pump having two chambers, a drive chamber driven by a remotely located active electric motor driven pump, and a pump chamber responsive to the drive chamber and connected to the sealed space. Fields generated by the motor of the electric pump do not interfere with the operation of the display tube.
