  • Patent number: 6351469
    Abstract: A TDMA in a CATV center and a CAU in a subscriber home communicate a B-ch idle/busy map indicating the idle/busy state of a B channel in synchronization with each other, so that the allocation of the B channel dedicated to sound and the C channel dedicated to data in a transmission frame can be dynamically changed according to the contents of the B-ch idle/busy map. Consequently, it becomes possible to effectively use a transmission bandwidth up to its maximum.

  • Patent number: 6297846
    Abstract: A display control system for a videoconference terminal capable of displaying proper images of participants. A video camera captures wide-angle source pictures including the images of participants. The source pictures are sent to a participant position detector and image clipping unit. The participant position detector detects a participant position by examining the source pictures. Depending on the on-screen movement observed in the participant position detected by the participant position detector, the image clipping unit determines an appropriate clipping window. It clips the desired image out of the source pictures as defined by the clipping window. A screen adjustment unit adjusts the image size so that it will fit to the actual screen size.

  • Patent number: 6283850
    Abstract: There is provided a circuit board cabinet which is capable of more reliably preventing flames of a fire in a shelf from spreading to external devices, without degrading cooling capability thereof. Flames of the fire occurring in the shelf rise within a slot, pass through a shield plate, and then enter a heat shield unit. In the heat shield unit, the flames are first blocked by a heat shield plate and substantially reduced in force while passing through holes formed through the heat shield plate. Portions of the flames which were not blocked by the heat shield plate reach a top board of the unit after passing through the holes, where they are reduced. Since there is a predetermined distance between the heat shield plate and the top board, the flames having passed through the heat shield plate spread horizontally to some extent and then reach the top board. Therefore, it is possible to reduce the force of the flames sufficiently by the top board.

  • Patent number: 6282237
    Abstract: A transmission system for transmitting a data signal with an analog passband signal through a analog transmission line. The data signal is transformed to a signal representing a descrete data signal point in a vector signal space. The analog passband signal is transformed to a base band signal, and the base band signal is superimposed on the signal representing a descrete data signal point. A signal representing the superimposed data signal point is modulated and transmitted through the analog transmission line. In a receiver, the data signal point is decided from the signal representing the superimposed data signal point, and the superimposed base band signal is extracted by subtracting the decided result from the signal representing the superimposed data signal point. The base band signal is transformed to the analog passband signal. A portion of information carried by the analog passband signal may be converted to a digital signal, and the digital signal is multiplexed with the data signal.

  • Patent number: 6282197
    Abstract: Disclosed is an ATM switching apparatus capable of reducing a probability an IAM acceptance being rejected due to a difference in bandwidth acquiring algorithm. The ATM switching apparatus is constructed such that when receiving an IAR due to the difference in bandwidth calculation algorithm for the IAM indicating a use of a certain VPC, a calculated bandwidth value is set in an estimated free bandwidth value about the VPC within a bandwidth management table, a value given by Calculation Bandwidth Value/Free bandwidth Value is set in a ratio, and the VPC is selected by using not the free bandwidth value but the estimated free bandwidth value (=Free Bandwidth Value×Ratio) when transmitting the IAM. It is another contrivance that when the free bandwidth value changes, the estimated free bandwidth value is also changed to establish “Estimated Free Bandwidth Value=Free Bandwidth Value×Ratio” without changing the ratio.
