Patent number: 6846986Abstract: RF emission may be reduced by providing grounding strips between optical transmitter and receiver modules in an optical transceiver package. The grounding strips includes an upper portion to fit over a top of the module, a transition portion to span a distance between the top of the module and the board, and a lower portion in electrical connection with a grounding pad on the board. The grounding strip may be substantially as wide as the module that it covers. Angled tabs may be provided to fit within registration holes in the ground pad. The grounding strip may be press-fitted onto the module or soldered. The low impedance ground strip increases the connectivity of the optical module to the board and may replace grounding leads to the external housing to reduce RF emissions.Type: GrantFiled: November 7, 2003Date of Patent: January 25, 2005Assignee: Intel CorporationInventors: Arie Ravid, Joshua T.

Patent number: 6473075Abstract: A method and apparatus for adapting an acoustic touchscreen controller to the operating frequency requirements of a specific touchscreen are provided. The adaptive controller can either utilize look-up tables to achieve the desired output frequency or the it can use a multi-step process in which it first determines the frequency requirements of the touchscreen, and then adjusts the burst frequency characteristics, the receiver circuit center frequency, or both in accordance with the touchscreen requirements. In one embodiment, the adaptive controller compensates for global frequency mismatch errors. In this embodiment a digital multiplier is used to modify the output of a crystal reference oscillator. The reference oscillator output is used to control the frequency of the signal from the receiving transducers and/or to generate the desired frequency of the tone burst sent to the transmitting transducers.Type: GrantFiled: September 29, 1999Date of Patent: October 29, 2002Assignee: Elo Touchsystems, Inc.Inventors: Paulo Irulegui Gomes, Shigeki Kambara, Hiroshi Kaneda, Joel Kent, Arie Ravid

Patent number: 6297811Abstract: An improved touchscreen utilizing two sets of electrodes that are fabricated in a single plane is provided. The individual electrodes of each set of electrodes are formed from a continuous length of a conductive material. Suitable electrode materials include fine wire and deposited conductive coatings. The overall electrode pattern is such that there is no overlap of electrodes, thus eliminating the need for insulating layers and/or coatings between electrodes. Although a variety of electrode patterns can be used, preferably the pattern is comprised of a plurality of approximately triangularly shaped electrodes, the pattern such that the base of one triangularly shaped electrode is adjacent to the apex of the next triangularly shaped electrode.Type: GrantFiled: June 2, 1999Date of Patent: October 2, 2001Assignee: ELO TouchSystems, Inc.Inventors: Joel Kent, Arie Ravid

Patent number: 5801933Abstract: A voltage converter and a method for converting AC to DC. A MOSFET (42, 118) conveys current from a full wave rectifier to charge a capacitor (60) that supplies current to a load (64). In a first embodiment, two transistors (32, 34) are connected as a differential pair to control the voltage applied to the gate of the MOSFET, referenced to a zener voltage developed across zener diode (36) that is connected to the emitters of the two transistors. In a second embodiment, a single transistor controls the voltage applied to the gate of the MOSFET, relative to a zener voltage of a zener diode (132). The MOSFET charges the capacitor while the voltage applied to its gate from the rectified signal is greater than the voltage across the capacitor.Type: GrantFiled: March 18, 1997Date of Patent: September 1, 1998Assignee: Abbott LaboratoriesInventor: Arie Ravid

Patent number: 5559528Abstract: Redundant segment display characters are used to provide a fail-safe indication of critical parameters. In one preferred form of the invention, selected segments of a redundant segment character include pairs of segments that are arranged proximate to each other and extend generally parallel to each other. The pairs of redundant segments are activated simultaneously in response to multiplexed fore plane and back plane drive signals applied to conductive regions of a liquid crystal display. The remaining portions of the redundant segment character each comprise single activated regions. The portions of the display character that include redundant segments are selected to minimize errors in reading a numeric value indicated by the character in the event that one of the segments fails to operate properly. In another preferred form of the invention, all of the portions of the character are pairs of redundant segments. In yet another embodiment, the pairs of redundant segments are arranged serially, end-to-end.Type: GrantFiled: September 21, 1993Date of Patent: September 24, 1996Assignee: Abbott LaboratoriesInventors: Arie Ravid, Robert G.

Patent number: 5517089Abstract: A power supply that converts an unregulated DC voltage source to a regulated AC power source suitable for energizing an electroluminescent panel. The DC voltage source powers a DC-to-AC inverter to generate an AC output. A feedback circuit monitors the AC output and compensates for any changes in amplitude that arise due to fluctuations in the DC input voltage. A single reference voltage is used to both selectively energize and deenergize the circuit and to control the amplitude of the AC output.Type: GrantFiled: October 28, 1993Date of Patent: May 14, 1996Assignee: Abbott LaboratoriesInventor: Arie Ravid
