Title: Terminating devices detection and verification circuit
Inventor: KUTZ DAVID A
IPC: H04L12/40
Filed: 1992-04-24
Granted: 1997-02-11
Abstract: A circuit for detecting and verifying a presence of a terminating device for a high speed data transmission line.  The circuit contains a first cable detector which generates a first signal if a first cable is present.  A second cable detector generates a second signal if a second cable is present.  The terminating device is contained in a plurality of resistor packs, each of the which contains an extra resistor.  A terminating device detector senses the extra resistor presence, thereby detecting the presence of the resistor packs.  The terminating device detector generates an ALL-EQUIPPED signal and a NON-EQUIPPED signal, the ALL-EQUIPPED signal is generated when all of the plurality of resistor packs are present, the NON-EQUIPPED signal is generated when all of the plurality of resistor packs are absent. Finally, a verifier circuit receives the first signal, the second signal, the ALL-EQUIPPED signal and the NON-EQUIPPED signal. The verifier circuit verifies that if the ALL-EQUIPPED signal is present then only one of the first signal or the second signal is present, or, if the NON-EQUIPPED signal is present both the first signal and the second signal are present.

Abstract: Screen (10) for a user interface of a television schedule system and process consists of an array (24) of irregular cells (26), which vary in length, corresponding to different television program lengths of one half hour to one-and-one half hours or more. Because of the widely varying length of the cells (26), if a conventional cursor used to select a cell location were to simply step from one cell to another, the result would be abrupt changes in the screen (10). By restricting cursor movements to the regular cells; abrupt screen changes will be avoided. A conventional offset shadow (34) which is a black bar underlines the entire cell and wraps around the right edge of the cell. To tag the underlying position which defines where the cursor (32) is and thus, where it will move next portions (36) of the black bar outside the current underlying position are segmented, while the current position is painted solid.

Abstract: A personal communications system is described which includes components of software and hardware operating in conjunction with a personal computer. The user interface control software operates on a personal computer, preferably within the Microsoft Windows® environment. The software control system communicates with hardware components linked to the software through the personal computer serial communications port. The hardware components include telephone communication equipment, digital signal processors, and hardware to enable voice, fax and data communication with a remote site connected through a standard telephone line. The functions of the hardware components are controlled by control software operating within the hardware component and from the software components operating within the personal computer. The major functions of the system are a telephone function, a voice mail function, a fax manager function, a multi-media mail function, a show and tell function, a terminal function and an address book function. The telephone function allows the present system to operate, from the users perspective, as a conventional telephone using either hands-free, headset or handset operation. The telephone function is more sophisticated than a standard telephone in that the present system converts the voice into a digital signal which can be processed with echo cancellation, compressed, stored as digital data for later retrieval and transmitted as digital voice data concurrent with the transfer of digital information data.

Abstract: A cylindrical diffuser tip (10) for use with an optical fiber is described. The diffuser tip comprises a silicone core (14) abutted to the terminus (13) of the conventional optically transmissive core (11) of an optical fiber, and an outer protective plastic tube (17) to provide controlled stiffness or rigidity to the silicone diffuser tip (1 0) while maintaining a flexibility comparable to that of the optical fiber. The scattering centers (16) embedded in the silicone core, ar e distributed to yield a particular light distribution pattern. For example, the scattering centers (16) may be distributed to provide a gradient that increases continuously in a direction perpendicular from the terminus face (13) of the optical fiber. The tip provides a substantially uniform distribution of radiance along its length and is particularly useful for laser radiation treatment of tum ors. The stiffness of the diffuser tip can be varied by choosing a protective tube (17) of varying wall thickness and durometer. Sinc e the cladding (12) surrounding the fiber core (11) remains intact, the strength of the diffuser tip is improved rendering the tip useful for providing uniform cylindrical illumination of a target tissue in remote areas of the body.
