Title: Apparatus for the intermittent storage and controlled feeding into the intake manifold of an internal combustion engine of volatile gasoline components
Inventor: SAUSNER ANDREAS
IPC: F02M25/08
Filed: 1991-11-05
Granted: 1996-12-03
Abstract: Disclosed is an apparatus for the intermittent storage and controlled feeding of volatile fuel components present in the unfilled space of a fuel tank into the intake manifold of an internal combustion engine, wherein a shutoff valve is positioned in a vent conduit which extends through a sensor and an absorption element into the intake manifold of the internal combustion engine.  The sensor is positioned in the conduit for production of a first signal which is proportional to the mass flow through the conduit.  An auxiliary arrangement produces a record signal for the operation of the shutoff valve, which second signal quantitatively corresponds to the valve position.  The auxiliary means compares the first with the second signal and an auxiliary device indicates deviations of the first signal from the second signal.  The fuel volatiles are thereby kept under control so that the stress on the environment caused by harmful substances emitted by the internal combustion engine is clearly reduced.

Title: Logic output driver
Inventor: JONES MARK ANTHONY
IPC: H03K19/00
Filed: 1993-06-25
Granted: 1998-09-29
Abstract: A programmable logic output driver includes a bias generator (100),  a current mirror (200)  and an output stage (300), there being a digital programming feature to maintain the output voltage slew rate at an acceptable value for either high or low values of load capacitances. The driver is programmable and can maintain a constant value of driver output resistance in the circumstances where the load voltage approaches the full swing logic voltage.   In the preferred embodiment,  the programmed output resistance is independent of variations in process, temperature and VDD supply voltage.  TTL loads are driven with  the  minimum  amount  of  required  output  current. Because of the constant resistance, the driver supplies a specified amount of current to the load even when the load is pulled down to a specified voltage.   The resistance value  is  substantially  the  highest  value  possible consistent with providing a required minimum load drive current  and  the  resistive damping of  the  output  RLC circuit  is  maximized  so  that  voltage   "kick"  or "undershoot" is held to a minimum.

Title: Adaptive compression of digital video data
Inventor: WU ALLEN
IPC: H04N7/26
Filed: 1994-03-09
Granted: 1998-12-22
Abstract: Digital video signals are adaptively compressed for communication to a receiver.  Superblocks, each containing a plurality of blocks of digital video data, are compressed using PCM, DPCM with a general motion vector for the entire superblock, and DPCM with a specific motion vector for each block contained within a superblock.  The result of each compression mode is compared after accounting for overhead data, to determine which results in the least amount of data for each block.   These blocks are assembled into a superblock, and compared together with necessary overhead and motion vector data to the same superblock processed using all PCM as well as the superblock processed using all DPCM. The comparison determines which compression mode produces the least amount of data for the superblock.  The most compact superblock is selected for transmission.  The transmitted superblocks are decoded by a decoder that recovers the necessary motion vectors and overhead information which identifies the type of compression used to provide the superblock.
