Title: Format conversion of digital video signals
Inventor: DORRICOTT MARTIN REX
IPC: H04N7/01
Filed: 1990-11-15
Abstract: In order to convert an input 60 field/s 2:1 interlace scan format digital video signal (col. A) to an output 24 frame/s 60 field/s 3232 pulldown format digital video signal (col. G), the input fields are repeated at a repeat rate of 4R times (col. B), one of each repeated field is temporarily stored (col. C), a 60 frame/s progressive scan format frame (col. D) is produced from the stored fields for every 4R repeated input fields, a 24 frame/s progressive scan format frame (col. E) is produced for every 10R repeated input fields from the 60 frame/s progressive scan format frames and repeated with a repeat rate of 5R times, with every other such frame being produced by motion compensated interpolation between successive pairs of the 60 frame/s format frames, and odd and even fields (col. F) are alternately output from the 24 frame/s format frames such that one field in every five is a repeat. <IMAGE>

Title: Manufacturing tined electrical contact
Inventor: SHEPHERD BRIAN
IPC: H01R43/16
Filed: 1991-09-16
Abstract: An electrical contact for insertion into a hole in a printed circuit board (3) is made by machining a circular blank (20) of phosphor bronze or beryllium copper to give it a triangular or other polygonal section (11) along a part of its length. A bore (21) is then drilled axially from one end of the blank, the radius of which is such that it breaks through the wall of the polygonal section (11) between its corners so that it is divided into e.g. three resilient tines. Alternatively, the blank is firstly bored and then machined externally to a polygonal shape again to break through the wall of the blank to form the tines. <IMAGE>

Title: A lifeboat escape system
Inventor: CONSTANTINIS DANNY ALEXANDER
IPC: B63C9/22
Filed: 1992-02-20
Abstract: An escape system to enable a group of people to escape in rapid succession from, for example, a marine platform, into a rescue craft, the system comprising a passageway (12) defining an exit, a stowed life raft (14) having a painter (16) connected to the passageway (12), a fixed rail (21) having thereon a plurality of travellers (24) each with a loop (25). Once the liferaft is launched personnel may escape successively each by a separate frictional descender. Each person attaches his descender to one of the travellers (24) which is then manoeuvred to a position (27) from which the descent will commence. After each descent the traveller (24) with the descender still attached thereto is moved further along the rail (21) to a remote end (23). During descent, each person will attach a sliding loop to the painter (16). Thus, there is no danger of personnel not reaching the rescue craft or of descenders becoming entangled since each descender will be moved in turn to the remote end (23) of the rail (21). <IMAGE>

Title: Method and apparatus for arbitrating data requests and responses thereto as separate bus transations.
Inventor: COOKE CONRAD CHARLES
IPC: G06F13/36
Filed: 1992-12-11
Abstract: A first and a second data handling node 10 are connected to a common data bus 20. Arbitration means AC - 0 to AC - 7, responsive to requests for control of the data bus 20 from the data handling nodes 10, for allocating control of the data bus 20 to selected data handling nodes 10 for successive access periods of a predetermined length T. The first data handling node requests control of the data bus for one of the access periods to transmit a data request R to the second data node. The second data handling node responds to the data request and requests control of the data bus 20 for a subsequent access period to transmit the requested data to the first data handling node. Data requests and the subsequent transmission of the requested data are thus treated as two separate bus transactions, each transaction taking place during an access period of a predetermined length. <IMAGE>

Title: Initialization mechanism for symmetric arbitration agents
Inventor: FISCH MATTHEW A
IPC: G06F13/362
Filed: 1994-12-19
Abstract: Multiple agents 302 - 305 on a bus are each initialized by power-on logic 310 with a different arbitration counter value. The arbitration counter 330 of each bus agent is used to keep track of which agent was the last or current owner of the bus and which agent will be the next owner of the bus. All bus agents agree on which agent will be the priority agent at system reset and thus be allowed first ownership of the bus. Each agent's arbitration counter 330 is initialized according to each agent's own agent identification 325. The arbitration pins 0, 1, 2, 3 of the bus agents are interconnected such that each agent determines for itself a unique agent identification based on which pin of its arbitration pins is active at system reset and the maximum number of bus agents allowed on the bus. A "rotary interconnect" scheme is used. <IMAGE>

Title: Vehicle internal noise reduction system
Inventor: TAMAMURA MANPEI
IPC: B60R11/02
Filed: 1994-12-23
Abstract: Pulls synchronized with the period of the noise are generated and input to an adaptive filter 4. The number of taps of the delay fine of the adaptive filter is determined in accordance with the interval of the input pulse. Thus the number of calculations for the adaptive filter 4 can be substantially reduced. Furthermore, when the tap number of the adaptive filter is changed due to a change of the period of the noise sound, a stored filter coefficient 17 for cutting the high frequency domain is convoluted into the tap value of the adaptive filter 4, whereby noises caused by the change of the tap number can be eliminated. <IMAGE>
