Patent CA-2055335-A1 (CA)
Title: Method for the transmission of data among mobile bodies or autonomous vehicles
Inventor: MICHALON GILLES
IPC: H04B7/26
Filed: 1991-11-12
Abstract: ABSTRACT OF THE DISCLOSURE    The disclosed method consists in constructing,  in each transmitter/receiver of a mobile body or  vehicle, information tables recording  the changes undergone  by the radio channel by the memorizing, during consecutive time intervals  of a  determined duration  dT that  are smaller  than  the  period  of  recurrence  T,  of  the statuses of the radio  channel, namely "in  collision", "busy" or  "free". It  then consists  in setting  fixed transmission  instants  in  each  transmitter/receiver, these  fixed  transmission  instants  being  temporally spaced out at intervals equal to the recurrence  period T, to predict the status of the channel for each  fixed transmission instant as a function of the status of the channel memorized at  the instant preceding  it with  a temporal shift equal to the  period T, and in  deciding to transmit at this instant if the predicted status  of the channel is not a status of collision or to transmit at an instant  deferred with respect  to the  predicted instant if  the  opposite  is  the  case.  Application: inter-city or urban road safety.

Title: Storage device array architecture with copyback cache
Inventor: BRANT WILLIAM A
IPC: G06F12/08
Filed: 1992-01-03
Abstract: A fault-tolerant storage device array using a copyback cache storage unit for temporary storage. When a Write occurs to the RAID system, the data is immediately written to the first available location in the copyback cache storage unit. Upon completion of the Write to the copyback cache storage unit, the host CPU is immediately informed that the Write was successful. Thereafter, further storage unit accesses by the CPU can continue without waiting for an error-correction block update for the data just written, In a first embodiment of the invention, during idle time for relevant storage units of the storage system, an error-correction block is computed for each "pending" data block on the copy-back cache storage unit, and the data block and corresponding error-correction block are copied to their proper location in the RAID system. The copyback cache storage unit in effect stores "peak load" Write data and then completes the actual Write operations to the RAID system during relatively quiescent periods of I/O accesses by the CPU. In a second embodiment of the invention, after Write data is logged to the copyback cache storage unit, normal Read-Modify-Write operation by the RAID system controller continues in overlapped fashion with other CPU I/O accesses using Write data in the controller's buffer memory.      Performance is enhanced because the CPU can continue processing as soon as the simple Write operation to the copyback cache storage unit completes, thus eliminating the delay caused by a normal Read-Modify-Write RAID system. in this embodiment, the copyback cache storage unit acts more as a running "log" of Write data.

Abstract: (Figure 2) ABSTRACT     ELECTRONIC TYPEWRITER         An electronic typewriter (11) has a line spacing device (29) for  rotating  a  platen roller (16) and a transport device (28) for moving a printing carriage (19) in  both  directions.      The  line spacing  and  transport  devices are driven from a single motor (32) via an intermediate gear (40) mounted on a shift member (35).    The shift  member  (35)  is displaceable between two operative positions for connecting a driveshaft (33) to the transport device (28) or  to the  line  spacing  device  (29).     A servomechanism (36) which is motorized by the shaft (33) displaces the shift member (35)  between the  two  positions  by  means  of  a shift electromagnet (81) which actuates a lever (79) to lock the gear (40) by means of  teeth  (88) on  a  slide  member  (43).    Positioning means (44) hold the shift member  (35)  in  each  of  the  two  operative  positions,  and  an electronic  control  means  (22)  controls  the  motor  (32) and the electromagnet (81).    The system is of low  cost,  and  is  simple, functional and reliable.

Abstract: A self-extinguishing blanket comprises an insulating layer of glass fiber strands (31) which include air spaces within the layer.  Each surface of the layer has a plastic film which extends continuously along the surface for keeping moisture out of the layer.  Each plastic film is attached to the associated surface of the insulation layer at selected areas (41) by a nonwoven fabric (37, 35). Each plastic film has a composition and embodies a stress condition which enables a portion of the plastic film, when subjected to a direct flame, or to the heat developed by an adjacent film, to soften, to pull apart, and to shrink and curl back, and to continue to curl back sufficiently far so as to prevent heating of that portion of the plastic film to ignition temperature.

Title: External memory system having programmable graphics processor for use in a video game system or the like
Inventor: SAN JEREMY E
IPC: A63F13/08
Filed: 1992-07-23
Abstract: A fully programmable, graphics microprocessor is disclosed which is designed to be embodied in a removable external memory unit for connection with a host information processing system.  In an exemplary embodiment, a video game system is described including a host video game system and a pluggable video game cartridge housing the graphics microprocessor.  The game cartridge also includes a read-only program memory (ROM) and a random-access memory (RAM).  The graphics coprocessor operates in conjunction with a three bus architecture embodied on the game cartridge.  The graphics processor using this bus architecture may execute programs from either the program ROM, external RAM or its own internal cache RAM.  The fully user programmable graphics coprocessor has an instruction set which is designed to efficiently implement arithmetic operations associated with 3-D graphics and, for example, includes special instructions executed by dedicated hardware for plotting individual pixels in the host video game system's character mapped display which, from the programmer's point of view, creates a "virtual" bit map by permitting the addressing of individual pixels -- even though the host system is character based.  The graphics coprocessor interacts with the host coprocessor such that the graphics coprocessor's 16 general registers are accessible to the host processor at all times.

Filed: 1992-09-11
Abstract: A mechanism for multiplying rotation.   The mechanism includes two armatures of differing lengths which rotate about different centers of rotation.    The armatures are coupled together such that a rotation of one armature will produce a multiplied rotation in the other armature.   The multiplying mechanism has particular application with a valve assembly of the type used in self-contained sanitary systems of recreational vehicles.  The valve assembly includes a seal element having a sealing lip directed toward generally inward and downward of a fill opening a valve blade in the holding tank.  The sealing lip terminates in a downwardly and outwardly oriented flange.  The valve blade is actuatable through two movements.   The first movement moves the valve blade generally vertically into and out of engagement with the seal element. The second movement moves the valve blade generally horizontally to a position out of registry with the fill opening.

Abstract: A blind rivet, especially for the production of rivet connections between load carrying components in aircraft construction, has a rivet shaft or mandrel with a thickened end and a pulling end.  The shaft has a conical section tapering from the thickened end to the pulling end.  Grooves run around at least the conical section.  The rivet mandrel or shaft is axially received in a rivet sleeve with a set head.  Adhesive is provided in the grooves, especially along the conical section of the blind rivet.  The adhesive hardens in the seam or gap formed between the rivet sleeve and rivet shaft when the blind rivet has been set.  This two-component blind rivet has a structural strength equivalent to that of a solid rivet so that it can also meet higher structural strength requirements.  Additionally, the adhesive prevents cold welding between the shaft and the sleeve and seals the gap.
