Title: System and method for generating an information display schedule for an electronic program guide
Inventor: HEYDT MICHAEL
IPC: H04N7/16
Filed: 1995-09-22
Granted: 2001-01-02
Abstract: An electronic program schedule system which includes a receiver for receiving television program schedule information and promotional information transmitted via satellite, a digital playback system for storing the schedule and promotional information and formatting pages of said information, and a cable television channel modulator for modulating the pages of information onto a cable television system. A data processor in the playback system receives and stores in a memory television program schedule information for a plurality of television programs to appear on the plurality of television channels. A television receiver is used to display the television program schedule and promotional information by tuning the receiver or cable converter box to the designated channel upon which the signals are modulated.  A multimedia generator receives control commands from the data processor and program schedule information from the memory and displays a portion of the program schedule information in either full screen grid format or partial screen grid format together with promotional information, as controlled by a schedule for display of the promotional information resident in the data processor. The data processor controls the multimedia generator with control commands, issued in response to a computer program resident on the data processor, to display program schedule information and promotional information.

Abstract: A method for selecting an electronic module from a plurality of at least two modules (M1, M2, M3) capable of emitting messages simultaneously, includes the steps of sending a general query message (ACTIVALL) to the modules, and selecting (AFI, SELECT-ID) the module having responded first, the modules, on receiving a query message (ACTIVALL, ACTIV), determining a random time interval (P) and sending a responding message (ID, R) when the said time interval (P) has elapsed. A module is set in idle position (IDL) when it receives a message (MESS) before the time interval (P) preceding the sending of a response (ID, R) has elapsed. The idle position (IDL) is at least characterized by the fact that one module does not respond, subsequently, to a complementary query message (ACTIV). This invention is particularly useful for contactless smart card readers and for terminals for electronic labels.

Abstract: With reference to a rope of load-bearing aramide fiber strands (9, 10, 11) laid parallel to each other in concentric layers of strands (14, 16), it is proposed to lay the strands (12) of an outermost layer of strands (12) with opposite lay to the rope core (19). As a result of the opposite lay, the torques which occur in the layers of strands (14, 16, 21) when under load cancel each other out; a non-twisting rope structure is achieved. An elastic intersheath (20) between the oppositely laid layers of strands (16, 21) serves to protect the strands (10, 11, 12) against abrasion and to transmit the torque over a wide area in the elevator rope (1).
