Patent number: 7379078Abstract: Described is a solution for controlling text symbol size on a display of a display unit based on a measurement of the distance between a remote control device and the display unit. A distance sensing module provides a distance measurement based upon detection of a transmitted signal from the remote control device. A symbol size calculation module determines a target symbol height based on the distance measurement, and a symbol size adjustment module adjusts the size of symbolic content on the display preferably using animation.Type: GrantFiled: October 26, 2005Date of Patent: May 27, 2008Assignee: Hewlett-Packard Development Company, L.P.Inventors: Richard C. Gossweiler, III, Eytan Adar

Patent number: 6178470Abstract: A configurable service processor for telemetry ground stations is totally implemented in VLSI/ASIC hardware and finds use in spacecraft systems and other communications systems that operate according to CCSDS and CCSDS-like protocols. The service processor performs the traditional functions of data extraction at very high data and packet rates.Type: GrantFiled: October 29, 1997Date of Patent: January 23, 2001Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: Jason T. Dowling

Patent number: 5903462Abstract: The invention described here in is a computer-implemented method and apparatus for controlling a hand-held tool. In particular, the control of a hand held tool is for the purpose of controlling the speed of a fastener interface mechanism and the torque applied to fasteners by the fastener interface mechanism of the hand-held tool and monitoring the operating parameters of the tool. The control is embodied in intool software embedded on a processor within the tool which also communicates with remote software. An operator can run the tool, or through the interaction of both software, operate the tool from a remote location, analyze data from a performance history recorded by the tool, and select various torque and speed parameters for each fastener.Type: GrantFiled: October 17, 1997Date of Patent: May 11, 1999Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Kenneth William Wagner, James Clayton Taylor

Patent number: 5802255Abstract: A system and method provides for the creation of a highly graphical expert system without the need for programming in code. An expert system is created by initially building a data interface, defining appropriate Mission, User-Defined, Inferred, and externally-generated GenSAA (EGG) data variables whose data values will be updated and input into the expert system. Next, rules of the expert system are created by building appropriate conditions of the rules which must be satisfied and then by building appropriate actions of rules which are to be executed upon corresponding conditions being satisfied. Finally, an appropriate user interface is built which can be highly graphical in nature and which can include appropriate message display and/or modification of display characteristics of a graphical display object, to visually alert a user of the expert system of varying data values, upon conditions of a created rule being satisfied.Type: GrantFiled: June 23, 1995Date of Patent: September 1, 1998Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Peter M. Hughes, Edward C. Luczak

Patent number: 5793328Abstract: A global positioning satellite receiver having an antenna for receiving a L1 signal from a satellite. The L1 signal is processed by a preamplifier stage including a band pass filter and a low noise amplifier and output as a radio frequency (RF) signal. A mixer receives and de-spreads the RF signal in response to a pseudo-random noise code, i.e., Gold code, generated by an internal pseudo-random noise code generator. A microprocessor enters a code tracking loop, such that during the code tracking loop, it addresses the pseudo-random code generator to cause the pseudo-random code generator to sequentially output pseudo-random codes corresponding to satellite codes used to spread the L1 signal, until correlation occurs. When an output of the mixer is indicative of the occurrence of correlation between the RF signal and the generated pseudo-random codes, the microprocessor enters an operational state which slows the receiver code sequence to stay locked with the satellite code sequence.Type: GrantFiled: April 1, 1996Date of Patent: August 11, 1998Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: John Ward, William S.

Patent number: 5726581Abstract: A capacitive type proximity sensor having improved range and sensitivity between a surface of arbitrary shape and an intruding object in the vicinity of the surface having one or more outer conductors on the surface which serve as capacitive sensing elements shaped to conform to the underlying surface of a machine. Each sensing element is backed by a reflector driven at the same voltage and in phase with the corresponding capacitive sensing element. Each reflector, in turn, serves to reflect the electric field lines of the capacitive sensing element away from the surface of the machine on which the sensor is mounted so as to enhance the component constituted by the capacitance between the sensing element and an intruding object as a fraction of the total capacitance between the sensing element and ground.Type: GrantFiled: March 8, 1996Date of Patent: March 10, 1998Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: John M. Vranish

Patent number: 5687255Abstract: A pre-coding method and device for improving data compression performance by removing correlation between a first original data set and a second original data set, each having M members, respectively. The pre-coding method produces a compression-efficiency-enhancing double-difference data set. The method and device produce a double-difference data set, i.e., an adjacent-delta calculation performed on a cross-delta data set or a cross-delta calculation performed on two adjacent-delta data sets, from either one of (1) two adjacent spectral bands coming from two discrete sources, respectively, or (2) two time-shifted data sets coming from a single source. The resulting double-difference data set is then coded using either a distortionless data encoding scheme (entropy encoding) or a lossy data compression scheme. Also, a post-decoding method and device for recovering a second original data set having been represented by such a double-difference data set.Type: GrantFiled: January 3, 1995Date of Patent: November 11, 1997Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: Pen-Shu Yeh
