Abstract: A toilet flushing mechanism includes a dual flush device for effecting both a short flush cycle and a long flush cycle in a toilet tank including a flush valve actuated by an actuation arm. A cam operable by a handle is rotatably supported adjacent the actuation arm.  When rotated in a first direction, the cam acts to press against and pivot the actuation arm to effect the long flush. When rotated in the second direction, the cam acts to press against and pivot said actuation arm to effect the short flush.  A lever is pivotably supported with respect to the actuation arm and pivots between a first position out of blocking contact with the actuation arm and a second position where the lever blocks return of the actuation arm for a predetermined period of time when the cam is rotated in the second direction.  A float is coupled to the lever for determining the predetermined period of time.  The float acts to pivot the lever into the second position when the cam is rotated in the second direction.   Where the toilet tank includes an overflow tube and a water control there is a trapway reseal device for the toilet tank.  The trapway reseal device includes a float slidably supported along the  overflow tube  to move with the changing level of water in the tank as the tank is flushed and refilled.  A reseal hose receives water from the water control and includes a free_ end coupled to the float.   The reseal hose selectively directs water into at least one of the tank and the overflow  tube  dependent  upon  the  position  of  the  float  as determined by the level of water in the tank.

Title: Integrated portable videoconferencing
Inventor: FORSBERG ROY W JR
IPC: G06F13/00
Filed: 1997-10-09
Granted: 2001-12-25
Abstract: A portable integrated videoconferencing unit has an integral housing in which an interior chamber houses an electronics board for performing video, audio, and communications processing.  Integrally mounted on the housing are a video camera and preferably a microphone array for providing directive audio processing.  The electronics board receives and processes video and audio outputs of the camera and microphone array respectively, and generates compressed video and audio outputs for transmission over the communications channel.  The electronics board also receives compressed video conferencing signals from the channel and processes those signals to generate the appropriate video and audio signals for connection to a video monitor.  Various elements are isolated from the microphones to reduce noise and vibration, and an answer bar can be mounted on the integrated unit to provide an easy known answer capability where an automatic answering mode is not desired.  The software of the unit can be upgraded during a videoconference call with an upgrade server.

Abstract: A first coefficient generating unit derives, from past reproduced speech signal, a first coefficient signal representing a spectral characteristic of the past reproduced speech signal.      A residual signal generating unit derives, from speech signal for each frame, a predicted residue signal by using the first coefficients. A second coefficient generator derives second coefficients representing a spectral characteristic of the predicted residue signal. A second coefficient quantizing unit quantizes the second coefficients and provides a quantized coefficient signal. An excitation quantizing unit derives an excitation signal concerning the speech signal by using the speech signal, the first coefficient signal, the second coefficient signal and the quantized coefficient signal, quantizes the second source signal thus derived and provides a quantized excitation signal. A reproduced signal generating unit reproduces a speech of the pertinent frame by using the first coefficient signal, the quantized coefficient signal and the quantized excitation signal.

Abstract: The Hepatitis C Virus (HCV) NS3 protein contains amino acid motifs of a serine proteinase, a nucleotide triphosphatase (NTPase), and an RNA helicase. A carboxy fragment of the HCV NS3 protein was purified and possessed RNA helicase activity. Defections from the amino terminus resulted in the protein becoming soluble. Deletions from the carboxy terminus do not result in a loss of helicase activity until at least 50 amino acids are deleted, the helicase activity requires ATP  and divalent cations such as Mg2+ and Mn2+. The helicase activity was blocked by monoclonal antibody specific to the HCV NS3 protein.
