Title: Portable work station and data collection terminal including switchable multi-purpose touch screen display
Inventor: DANIELSON ARVIN D
IPC: G06F1/32
Filed: 1994-02-28
Abstract: A portable data collection terminal (10) has an elongate housing (12) with a hand grip conforming rear surface. A front surface (14) features a numerical keyboard (16) adjacent a lower end of the housing and an LCD screen (15) adjacent the keyboard toward an upper end of the housing. The display screen is of elongate rectangular shape, its length extending longitudinally of the housing of the data terminal. The active area of the display screen is covered by a touch sensitive overlay screen which is configured in one mode of operation of the data terminal into an alphabetical keyboard. The orientation of the display is switchable between orientations in which the line direction of the displayed data extends across or longitudinally of the data terminal. The keys (46), of the numerical keyboard (16) are identified by indicia (42) disposed on a template (13). The orientation of the template may be sensed to switch the orientation of the displayed data and touch sensitive key idendfiers to correspond to the orientation of the indicia on the template. As a further embodiment an electromagnetic activation by a pen may be used to enter data into a data terminal. Power saving shutdown extends the battery life of the data terminal. A shutdown mode permits resumption of operation by depression of a key.

Title: Apparatus providing dynamic virtual service selection in a multi-service communications system
Inventor: THATCHER WILLIAM BRADFORD
IPC: H04N7/24
Filed: 1994-03-04
Abstract: An apparatus providing a dynamic virtual service capability in a multi-service communications system is claimed. A dynamic virtual service comprises an associated group of basic services wherein only one of the basic services in the group is active at any time. Basic services comprise a number of service components which are transmitted to the apparatus on one or more of a plurality of different frequency channels. The apparatus comprises a service selection switch for selecting either one of the basic services directly or one of the dynamic virtual services. A dynamic virtual service map is provided that defines for each dynamic virtual service, on a time-varying basis, the currently active one of the group of basic services that comprises that dynamic virtual service. Means responsive to the service selection switch and to the dynamic virtual service map are provided for automatically selecting the currently active basic service of a subscriber selected dynamic virtual service. Finally, the apparatus provides means for receiving and accessing the service components of a selected basic service from the frequency channel carrying those components. According to one embodiment, dynamic virtual service map definitions are periodically retransmitted to the apparatus on each frequency channel carrying service components of one of the group of basic services that comprise that dynamic virtual service. Additionally, a "home" basic service may be defined for each dynamic virtual service. When a dynamic virtual service is initially selected by a subscriber, the apparatus initially "tunes" to the frequency channel carrying the service component of that home basic service.

Title: System for body impedance data acquisition and multiple frequency impedance
Inventor: LIBKE ALBERT W
IPC: A61B5/00
Filed: 1995-09-11
Abstract: The unique system of the present invention provides an accurate valid measurement of human body composition consisting of fat tissue, ?ean tissue and body water. The inventive methodology provides a procedure for quantitative measurement of the conductive potential of the body, which is based on the lean tissue content of the body, in a convenient and reliable manner.          In more detail, the quantitative measurement in accordance with the present invention is referred to as a "bio-impedance signal".          This electrical signal, in ohms, is derived from a means for measuring body impedance component of the system. The resultant signal (three digit number, between 1 and 1,000 ohms) is then entered into a modifying means component to accurately predict the body composition of the tested individual. The unique modifying component, in one embodied form, comprises prediction formulas derived from biological data inputs including: a patient's height, weight, age, and sex to determine a "population prediction variable". Thus, the unique modifying component of the inventive system interprets bio-impedance readings as "population specific", i.e., specific impedance values are exhibited by various predefined populations of individuals. This specificity is related to morph-type, leanness, body water and age.

Title: Trellis demapper of a convolutional decoder for decoding pragmatic trellis codes suitable for use in a multi-channel receiver of satellite, terrestrial and cable transmitted fec compressed digital television data
Inventor: RAMASWAMY KUMAR
IPC: H04N19/89
Filed: 1996-08-29
Abstract: The trellis demapper, which is capable of demapping 8-PSK and 16, 32, 64, 128 and 256 QAM trellis codes, comprises respective I-channel, Q--channel and remapper RAMs, an 8-PSK demapper logic means and a MUX selects. Each of the RAMs includes a lookup table is selectively programmed for each of the QAM codes. The I-channel RAM and the Q--channel RAM, each of which has a storage capacity of 768 bits, directly forwards their respective outputs through the MUX selects as the trellis demapper output in response to a QAM trellis code which is an even power of 2 (i.e., 16, 64 or 256) being selected. In response to a QAM trellis code which is an odd power of 2 (i.e., 32 or 128) being selected, the respective outputs of the I-channel RAM and the Q-channel RAM are applied as inputs to the remapper RAM, which has a storage capacity of 320 bits, and the output of the remapper RAM is forwarded through the MUX selects as the trellis demapper output. In response to an 8-PSK trellis code being selected, the output of the 8-PSK demapper logic means is forwarded through the MUX selects as the trellis demapper output. This configuration is structurally efficient and requires minimum storage requirements compared to a trellis code demapper employing ROM storage for the 16, 32, 64, 128 and 256 QAM and 8-PSK trellis codes.
