摘要:
A vector-quantizing device comprises a first code book for storing a plurality of code vectors at respective addresses; a first addressing unit for selecting a code vector stored in the first code; a synthesis unit supplied with the code vector from the first code book for producing a synthetic signal that simulates an input signal; an evaluation unit supplied with the input signal and further with the synthetic signal from the synthesis means for evaluating a difference therebetween and searching for a code vector that minimizes the difference. There, the evaluation unit produces the first index data that specifies a code vector wherein the difference is minimized as a coded output. In addition, the vector-quantizing device includes a second code book for storing a plurality of code vectors at respective addresses; a second addressing unit for selecting a code vector stored in the second code book: and an update unit for counting the frequency of selection of the code vectors for each of the code vectors stored in the first code book. There, the update unit is for replacing a code vector in the first code book, when the frequency of use of the code vector is below a predetermined threshold, with a code vector in the second code book.
摘要:
The invention provides a synchronism establishing method and apparatus including a plurality of modules having different independent synchronization patterns to be switched wherein the switching transition process having a time length corresponding to the number of protection stages necessary for pull in and protection of synchronism is reduced so small that the presence of such switching transition process can be ignored while assuring similar advantages to those of conventional synchronism establishing apparatus. A master side module delivers a notification of establishment of synchronism thereof to a slave side module. When the slave side module is in a condition wherein synchronism is established, it puts its synchronizing operation into a waiting mode. Even if it thereafter detects a number of abnormal synchronization patterns greater than the number of protection stages, it does not determine a pull out condition and maintains the pulled in phase. If the slave side module detects a false pull out condition from the master side module, the slave side module determines that synchronism is entered therewith and resumes its processing operation.

Speech is data-compressed and coded for transmission using TDHC (Time Domain Harmonic Compression) for the voiced signal, and decimated sampling for the unvoiced signal. Features include voiced/unvoiced detection, pitch period detection, border detection, coding by ADPCM, and optimum quantization coding. Reception involves decoding and data-reconstruction.

摘要:
A robot, capable of appropriately adjusting position and/or posture on a current spot to execute a designated task involving interaction with a target object.The Robot is configured to enable adjustment of the position and/or posture by controlling movement of at least a hip joint mechanism, and a knee joint mechanism in the spot while the robot is allowing each foot to keep its floor-arriving state. Accordingly, when the position and/or posture is inappropriate to execute the designated task while the robot is at a standstill in a second designated area for executing the designated task, the robot can execute the designated task after the position and/or posture has been corrected in the second designated area.
摘要:
Vehicle-mounted fuel cell stack includes one or more cooling cells and an air allocation mechanism. Via the allocation mechanism, air flowing in a front-to-rear direction of the vehicle is introduced through reacting-air introduction openings of power generating cells and also introduced through cooling-air introduction openings of the cooling cells, so that the power generating cells can be cooled by the cooling cells. Sliding movement of the air allocation mechanism can allocate the cooling air and reacting air in desired amounts, so that it is possible to not only appropriately deal with an increase in the power generation amount but also appropriately remove excessive heat. Because the cooling cells are each constructed of thin metal plates, they can effectively remove a great amount of heat produced from power generating cells, with an enhanced efficiency.
摘要:
Temperature of power generating cells is measured, and, if the measured temperature is lower than a preset standard operating temperature, control is performed for zeroing an allocated amount of cooling air via an air allocation mechanism. During a startup period, cooling-air introduction openings are closed with reacting-air introduction openings kept open and an air-sucking-in fan activated. Thus, the entire amount of introduced air is caused to flow through the reacting-air introduction openings into the cells for reaction with hydrogen with a minimized cooling effect so that the power generation reaction can be promoted, which can reduce a time necessary for the cell temperature to increase up to a predetermined operating level. By constantly performing the control for zeroing the allocated amount of cooling air during the startup and subsequent periods, the power generating cell temperature is constantly allowed to rise readily as desired.
摘要:
A stack of a polymer electrolyte fuel cell is immersed in a stack container case, in a liquid coolant such as an organic solvent, and the stack is operated in this state. The stack whose temperature has risen by heat energy produced by the operation is cooled by the liquid coolant. The liquid coolant which has cooled the stack vaporizes, and is condensed by a condenser. Then, the liquid coolant returns to the stack container. The condenser is cooled when the outside air is supplied into supply louvers, and contacts the condenser. The outside air is efficiently discharged by exhaust fans through exhaust louvers.
