Title: Monitor or tv receiver using a secondary analog signal path for displaying osd signals from external sources
Inventor: USUI HIROFUMI
IPC: H04N21/41
Filed: 2000-02-02
Abstract: An external source (100) outputs an analog signal containing on-screen information (OSD) for the external source (100), which has been decoded in the external source (100), and an encoded high definition digital signal. A high definition television (HDTV) (120) has separate inputs (150, 170) for the analog signal and the high definition digital signal, which is decoded in the HDTV (120) to a format suitable for display on the HDTV monitor (140).  Accordingly, both the OSD information for the external source (100) and the high definition signal are available for use and display on the HDTV monitor (140).

Title: Speech enhancement with gain limitations based on speech activity
Inventor: MARTIN RANIER
IPC: G10L25/84
Filed: 2000-02-09
Abstract: An apparatus and method for data processing that improves estimation of spectral parameters of speech data and reduces algorithmic delay in a data coding operation. Estimation of spectral parameters is improved by adaptively adjusting a gain function used to enhance data based on whether the data contains information speech and noise or noise only. Delay is reduced by extracting coding parameters using incompletely processed data.

Patent CA-2373734-A1 (CA)
Inventor: DOYLE JOHN P
IPC: E21B23/01
Filed: 2002-02-28
Abstract: A tool is provided for preventing the rotation of a downhole tool or rotary pump stator, the tool comprising a tubular housing and a jaw which is biased radially outwardly from the tool to engage the casing wall for arresting tool rotation and providing significant stabilization of a rotary pump. In doing so, the tool housing moves oppositely to rest against the casing opposite the jaw. The tool housing and the downhole tool are thereby restrained and stabilized by the casing wall. The tool's jaw is released by opposite tool rotation. Preferably, the jaw is biased outwardly from the tool housing to a casing-engaging position by a torsional member, housed along the axis of the hinge of the jaw. The tool is released from the casing by opposite tool rotation which increasingly compresses the jaw toward the housing, twisting the torsional member into torsion, which then acts to urge the jaw outwardly again.

Inventor: VAN CLEVE CRAIG BRAINERD
IPC: G01F1/84
Filed: 2000-06-13
Abstract: Method and apparatus for providing compensation of mass flow rate and density for the flow tube of a single straight flow tube Coriolis flowmeter. Thermal stress compensation is provided by the use of a plurality of sensors on various portions of the flowmeter. A first sensor is coupled to the flow tube and provides information regarding the flow tube temperature. A plurality of additional sensors are connected to form a network having a two wire output.  The additional sensors apply a composite signal over the two wire output of the network to meter electronics. The network signal represents the composite temperature of the flowmeter elements that can cause thermal stress on the flow tube when a temperature differential exists between the flow tube and the temperature of these plurality of elements. The additional elements include the balance bar and the flowmeter case. Sensitivity compensation is provided by the use of a novel algorithm. Density is measured in a single tube flowmeter that is calibrated using two materials of different densities by the use of density equation that has non-linear components representing the deviation of the meter calibration from linear.

Title: Method for predicting quantitative values of a rock or fluid property in a reservoir using seismic data
Inventor: WILSON STEPHEN D
IPC: G01V1/30
Filed: 2001-05-18
Abstract: A method (Fig. 1) is provided for predicting a value of a designated rock or fluid property in a subterranean geologic volume (10). An experimentally determined seismic value of acoustic impedance is assigned to a model volume correlated to the subterranean geologic volume (10). At first predicted value of the designated rock or fluid property is also assigned to the model volume.   A first predicted value of acoustic impedance for the model volume is calculated from a response model using the first predicted value of the designated rock or fluid property, wherein the response model is responsive to changes in predicted values of the designated rock or fluid property. The first predicted value of acoustic impedance is compared to the seismic value of acoustic impedance to determine a difference between the predicted and seismic values of acoustic impedance. The first predicted value of the designated rock or fluid property is adjusted in response to the difference to create a second predicted value of the designated rock or fluid property, wherein the second predicted value reduces the difference.
