Title: Electronic unit retention system
Inventor: FURUTA STEVEN J
IPC: E05B47/00
Filed: 1990-09-04
Abstract: An electronic Unit Retention System.  With the present invention, electronic modules are kept retained within a system housing so long as power supplied to the module.  A bracket is mounted within a module along its back wall.  One or more guide pins extend from a back plane of the housing towards the center of the unit.  A solenoid is mounded on the bracket and connected to the module's internal power supply.  The solenoid is connected to the power supply in such away that whenever power is supplied to the module, the solenoid is energized.  The solenoid is designed such that when power is disconnected from the solenoid, and the solenoid is de-energized, the solenoid pin in the solenoid is withdrawn into the solenoid body.  When the solenoid is energized, the solenoid pin extends.  The solenoid is mounted on the bracket in such a way that when the pin is extended, it interacts with the guide pin and prevents the module from being moved.  The solenoid pin contacts the guide pin tangentially.  Contact is made in a location where the diameter of the guide pin is narrower than the rest of the pin.  The solenoid pin is locked into position in this recessed portion and prevents the module from moving.

Title: Process and apparatus for timed port injection of fuel to form a stratified charge
Inventor: INGLE WILLIAM D III
IPC: F02B43/00
Filed: 1990-11-13
Abstract: ABSTRACT OF THE DISCLOSURE         A process and apparatus for timed port injection and enriched stratified charge of fuel, preferably gaseous fuel, into an internal combustion engine.  The process begins with forming a lean fuel/air mixture with a first fuel portion in an intake manifold upstream of a port injector.  The lean fuel/air mixture is uniformly distributed into a combustion chamber during an intake phase of an engine cycle.  A subsequent fuel portion is injected in a controlled manner during the intake phase so as to form a stratified charge near the ignitor within the cylinder.          The stratified charge within the cylinder is ignited and combusted.  Combustion products are then exhausted from the combustion chamber.  This invention also provides an apparatus and process for injecting a gaseous fuel within a combustion chamber to form an enriched portion of a stratified charge near the ignitor.

Title: Method of transmitting a picture sequence of a full-motion video scene, and a medium for said transmission
Inventor: HAAN WIEBE DE
IPC: H04N7/24
Filed: 1991-05-31
Abstract: A compact disc-like display device is adapted to display a sequence of pictures which jointly represent a full-motion video scene, which picture sequence is digitized by means of some suitably chosen encoding algorithm. The digitized picture sequence comprises a series of video blocks. Since the disc continues to rotate at the normal speed when the picture sequence is displayed in slow motion, or in the case of a freeze, discontinuities in the display of the picture sequence are produced. To inhibit this, a header referring to a predetermined video block, preferably the next block, is associated with each video block so that the display device has information about that picture which is to be displayed next. The display device searches, reads and processes the associated video block on the disc.

Abstract: GENERIC ENCRYPTION TECHNIQUE FOR COMMUNICATION NETWORKS                        ABSTRACT OF THE DISCLOSURE          A method and related cryptographic processing apparatus for handling information packets that are to be cryptographically processed prior to transmission onto a communication network, or that are to be locally cryptographically processed and looped back to a node processor. A special cryptographic preamble is included in each information packet that is to be subject to cryptographic processing.  The cryptographic preamble contains an offset value pointing to the starting loca-tion of information that is to be processed, and com-pletely defines the type of cryptographic processing to be performed. The cryptographic processor can then per-form the processing a  specified in the preamble with-out regard to a specific protocol. If the packet is to be transmitted onto the network,  the preamble is stripped from the packet after cryptographic process-ing, so that the formats of packets transmitted onto the network will be unaffected by the preamble. Crypto-graphic processing modes include encryption of data for outbound transmission,  encryption of a cipher key for loopback to the node processor,  encryption or decryp-tion of data for loopback to the node processor, and computation of an integrity check value for loopback to the node processor.
