Abstract: ABSTRACT OF THE DISCLOSURE           A voice recognition dialing unit of a telephone mounted on a vehicle or similar mobile body and which allows a call to be originated with ease.  When the user of the telephone enters a voice command on a voice inputting section, the dialing unit originates a call automatically and thereby connects the other party to the telephone line. In a call origination procedure, the operations for call origination and verification are performed between the user and the unit in an interactive sequence.  In a preferred embodiment,  the unit has a particular call origination procedure in which, when the other party recognized by the unit  is  incorrect,  as  determined  by  the  user  by verification, lower-place candidates for the other party are called up in repones to a particular voice command.  In an alternative embodiment, the unit indicates the other party by uttering a name for verification purposes.  This alternative embodiment has means for selecting and storing only the name of the other party in response to an entered voice  signal  and,   in  the event  of  response  for verification, combining the name having been stored in this means and response information stored beforehand to produce a composite voice response.

Abstract: A SYSTEM FOR COMPRESSION AND DECOMPRESSION OF VIDEO DATA USING DISCRETE COSINE TRANSFORM AND             CODING TECHNIQUES                Alexandre Balkanski Stephen C. Purcell James W. Kirkpatrick, Jr.        Mauro Bonomi Wen-Chang Hsu ABSTRACT OF THE DISCLOSURE     A digital video compression system and an apparatus implementing this system are disclosed.  Specifically, matrices of pixels in RGB, YUV or CMYK formats are accepted for data compression.  The data are rearranged in 8x8 pixel blocks, each block being of one pixel component type. The pixel data are then subjected to a discrete cosine transform (DCT). A quantization step eliminates DCT coefficients having amplitude below a set of preset thresholds.  The video signal is further compressed by coding the elements of the quantized matrices in a zig-zag manner.  This representation is further compressed by Huffman codes.  Decompression of the signal is substantially the reverse of compression steps.  The inverse discrete cosine transform (IDCT) may be implemented by the DCT circuit.  The circuits may be implemented in a single integrated circuit chip.  Three levels of compression rate control are provided during processing of video data.

Patent CA-2043546-A1 (CA)
Inventor: VON BERGEN ERNST-PETER
IPC: B63H23/32
Filed: 1991-05-30
Abstract: A lubrication system for a rotatable propeller shaft of a ship.  The system includes a seal for sealing lubricant adjacent the shaft and at least one annular chamber defining a hose-shaped inflatable body.  A ring line supplies a fluid heat transfer medium, such as air, to the at least one annular chamber.  The heat transfer medium is heated by a heat source.  The heat transfer medium may also act as a pressure medium to inflate the inflatable body.  The heat transfer medium can be circulated so that when the propeller shaft is stationary in an extremely cold liquid medium, such as icy sea water, the inflatable body is inflated by the heat transfer medium so that the inflatable body expands to within a major portion of the at least one annular chamber while, simultaneously, heating lubricant in the remaining portion of the annular chamber. Such heating causes the lubricant viscosity to approximately equal the viscosity of the lubricant when the propeller shaft rotates and the lubricant is not heated. During rotation of the propeller shaft, the inflatable body is deflated out of the annular chamber.
