Title: Information receiving system for descrambling scrambled information and presenting the descrambled information
Inventor: USHIYAMA TAKAO
IPC: H04N21/4405
Filed: 1994-11-01
Abstract: A TV signal that was scrambled and transmitted, e.g. from a CATV center is tuned by a TV tuner for a "parent" unit (1) or a TV tuner for a "child" unit (2) based on a command received from a microprocessor. The tuned TV signal is input to a descrambler (3) provided in the parent unit. The descrambled TV signal is input to a synthesizing unit for the parent unit or a synthesizing unit for the child unit. When the parent unit or the child unit cannot receive a desired pay channel program because the other unit is already receiving it, the microprocessor causes a character generating unit to generate a message that indicates that a pay channel program cannot be watched. This message is synthesized with a TV signal by the respective synthesizing unit and then output to a TV receiver (6) of the parent unit or a TV receiver (7) of the child unit. <IMAGE>

Inventor: KENNEDY ANDREW NEIL
IPC: A63F9/00
Filed: 1995-03-27
Abstract: A game is provided wherein a first player selects a combination to be guessed by a second player. The combination is selected by switching a chosen combination of switches 1a to 1e into the "down" position. The second player then guesses the combination by inserting one or more pegs into apertures 5a to 5e to activate corresponding switches 7a to 7e. When all of the selected switches, e.g. 1a, 1b and 1c, have pegs inserted in the corresponding apertures 5a, 5b and 5c, a buzzer and/or a flashing light is energised to indicate to the second player that the correct combination has been guessed. The insertion of a peg in one of the apertures causes a switch to be operated, and a circuit is completed when pegs have been inserted into the "correct" apertures. In an alternative embodiment, the apertures are arranged within a circular cylinder to mimic a uranium pile, with the pegs to be inserted constituting moderator rods.

Title: Monitoring GPS ephemeris data
Inventor: KYRTSOS CHRISTOS T
IPC: G01S5/14
Filed: 1993-10-20
Abstract: The position of a satellite (102) in a satellite based navigation system (200) is determined without reliance on satellite ephemeris data. Orbital parameters are computed for each satellite (102). The orbital parameters can then be used to predict the position of each satellite (102) at any time. Subsequent ephemeris data is compared to a predicted satellite position to determine whether the ephemeris data is corrupt. The orbital parameters may be determined by: computing a pseudorange and a velocity for a selected satellite (102) for a plurality of times, computing at least three estimated positions of the satellite (102) from the pseudoranges and velocities, and computing orbital parameters for the satellite from the three estimated positions. In another example, the orbital parameters are determined by: determining the position of a receiver (400) for at least three times using a constellation of satellites (102), using the three receiver positions to triangulate on an average position for the selected satellite (102) in the constellation, repeating these steps until at least three mean satellite positions have been computed, computing the orbital parameters from the three mean positions of the selected satellite (102). <IMAGE>

Title: Multi-tasking computer system has shared address space among multiple virtual address spaces
Inventor: MUNROE STEVEN JAY
IPC: G06F12/10
Filed: 1997-12-02
Abstract: A multi-tasking computer operating system allocates a respective virtual address space to each task. A portion of virtual address space is reserved as a shared address space (SAS) region 510, the SAS region occupying the same range of virtual addresses in the virtual address space of each task. Outside the SAS region the mapping of entities in virtual memory is handled in the same way as in in a conventional multiple virtual address space architecture. Certain classes of data intended for sharing among multiple tasks are assigned unique and persistent addresses in the range of the shared address space region. Preferably, certain facilities are added to a conventional base operating system to support the SAS region and associated function. These include a join facility for initiating a task to the SAS region, an attach facility for attaching blocks of memory within the SAS region, and a paging facility for retrieving a page within the SAS region from storage. In this manner, it is possible for a multi-tasking multiple virtual address space computer system to assume the advantages of a single-level store computer system when performing certain tasks.
