Title: Multimedia collaboration system
Inventor: LAUWERS CHRIS J
IPC: H04N7/15
Filed: 1994-03-16
Abstract: A collaboration system that integrates separate real-time and asynchronous networks - the former for real-time audio and video, and the latter for control signals and textual, graphical and other data - in a manner which closely approximates the experience of face-to-face collaboration. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. The system architecture is readily scalable to the largest enterprise network environments. It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations (12) and their interconnecting LANs (10) and WANs (15). In the case of a plurality of geographically dispersed LANs (10) interconnected by a WAN (15), the demands made on the WAN are significantly reduced by employing multi-hopping techniques, including avoiding the unnecessary decompression of data at intermediate hops, as well as video mosaicing and cut-and-paste technology.

Title: Method and apparatus for controlling the transition of an audio signal converter between two operative modes in the presence of link impairments in a data communication channel
Inventor: SLOAN DAVID G
IPC: H04L1/00
Filed: 2000-02-18
Abstract: A signal processor for effecting the conversion of an audio data signal from one format to another. The signal processor has a signal converter that can selectively acquire two operative modes, namely a first operative mode and a second operative mode. In the first operative mode, the signal converter transforms the audio data signal from one format to another and releases the converted audio data signal from the output of the signal processor. In the second operative mode, the signal converter is disabled and permits passage of the audio data signal to the output without conversion. The signal processor has a control unit for controlling the transition of the signal converter between operative modes. The control unit enables the signal converter to pass from the first operative mode to the second operative mode when at least one operative condition has been satisfied. The control unit reacts to a link impairment occurring on the data communication channel to alter the operative condition to be satisfied to enable passage from the first operative mode to the second operative mode. In a specific example of implementation, the modification to the operative condition can be such as to "tighten" the requirements to be met for switching from the first to the second operative mode.

Abstract: The invention relates to a method and device for improving the current quality of a superimposed network (14) by means of a compensation device (2) which is connected parallel to the network (14) and to a load (12) and provided with a pulse current converter (4). The control and regulating system (10) of the converter determines a transmittance space vector (ü) on the basis of a supply voltage and line current space vector (uN,iN) together with the actual value of a direct current voltage(Vdc). According to the invention, a compensated voltage fundamental space vector (uk,1) comprising a space vector for a compensated voltage fundamental positive phase sequence system and a space vector for a compensated voltage fundamental negative phase sequence system is generated. This enables the compensation device (2) to balance a high dynamic load and to compensate reactive power in relation to the fundamental frequency currents of a particular load (12), so that said load (12) when seen from the point of view of the superimposed network in relation to the fundamental mode can appear as a three-phase, symmetrical, ohmic resistance.

Title: Received-signal absolute phasing apparatus of receiver
Inventor: HORII AKIHIRO
IPC: H04L27/22
Filed: 1998-12-11
Abstract: When reception of a multiplexed wave to be PSK-modulated of BPSK, QPSK, and 8PSK is started, a selector (16A) of a demodulating circuit (1A) reads high-order three bits .DELTA..phi.(3) of phase error data corresponding to I and Q symbol streams out of one phase error table (15-1) for BPSK among phase error tables provided for each modulation system and each phase rotation angle. A received-signal-phase rotation angle detecting circuit (8A) detects phase rotation angles of portions corresponding to bits (1) and (0) of a frame-synchronizing signal of a received symbol stream from the .DELTA..phi.(3) and the MSB of I symbol stream and outputs the phase rotation angles to a remapper (7) to make the remapper perform absolute phasing. The selector (16A) reads phase error data corresponding to a received symbol stream out of a phase error table corresponding to a modulation system and a phase rotation angle identified by a transmission-configuration identifying circuit (9), outputs the phase error data to a D/A converter (17), corrects a phase of a reference carrier wave for orthogonal detection, and makes a received-signal point become a constant phase for a transmitted-signal point.

Title: Structure for supporting rotary shaft
Inventor: MURAI YUKIO
IPC: B01D63/16
Filed: 2000-08-15
Abstract: A rotary shaft (20) is inserted to a tank (12) through a hole (22) formed in a wall of the tank (12). A casing (30) is provided outside the tank (12), and the rotary shaft (20) is supported by a bearing (76) arranged in the casing (30). The casing (30) is watertightly connected to the wall including the hole (22) through a flexible joint (34). Seal members (50, 52, 60) are arranged in the casing (30) to seal the clearance (22a) between the rotary shaft (20) and the casing (30). A sleeve (64) is fitted on the rotary shaft (20) so that the sleeve (64) is watertightly in contact with at least one of the seal members (50, 52, 60), and the sleeve (64) can be moved along the rotary shaft (20) to change the seal member (50, 52, 60) in contact with the sleeve (64). The bearing (76) and the seal member (50, 52, 60) are not affected by the deformation of the tank (12) since the flexible joint (34) connects the tank (12) and the casing (30), and the rotary shaft (20) can rotate smoothly while securing high sealing quality. The alignment of the axes of the bearing (76) and the hole (22) in the tank (12) can be easy since the bearing (76) is provided outside of the tank (12), and thus assembly and maintenance of the structure are easy. The tank (12) can have relatively low strength since the tank (12) has not to support the rotary shaft (20) with the bearing (76); thus the structure can be compact and the cost can be reduced.
