Patent CA-2111290-A1 (CA)
Inventor: LIN DANIEL
IPC: G10L19/07
Filed: 1993-12-13
Abstract: A line spectral frequency (LSF) vector quantizer, having particular application in digital cellular networks (DCN), is provided for code excited linear predictive (CELP) speech encoders. The LSF vector quantizer is efficient in terms of bits employed, robust and effective in terms of performance across speakers and handsets, moderate in terms of complexity, and accommodates effective and simple built-in transmission error detection schemes. The LSF vector quantizer employs a minimum number of bits, is of moderate complexity and incorporates built-in error detection capability in order to combat transmission errors. The LSF vector quantizer classifies unquantized line spectral frequencies into four categories, employing different vector quantization tables for each category. Each quantization table is optimized for particular types of vectors. For each category, three split vectorcodebooks are used with a simplified error measure to find three candidate split quantized vectors. The three sets of three split vectors are combined to produce as many as 27 vectors from each category. The quantizer then makes a final selection of optimal category, using a more complex error measure, to achieve the robust performance across speakers and handsets. Split vector quantization follows a two stage constrained search procedure that results in an ordered set of quantized line spectral frequencies that is "close"to the unquantized set with moderate complexity within each category. Effective and simple transmission error detection schemes at the receiver are made possible by the split nature of the vector quantization and the constrained search procedure. Only twenty-six bits are required to encode ten line spectral frequencies.

Title: Process for identifying patterns of electric energy consumption and demand in a facility, predicting and verifying the effects of proposed changes, and implementing such changes in the facility to conserve energy
Inventor: CMAR GREGORY
IPC: G05D23/19
Filed: 1994-02-22
Abstract: ABSTRACT     A process for identifying patterns of electric energy or similar supplied resource consumption and demand in a facility and determining possible changes in the facility for such energy or similar conservation, using, in the case of electric energy, monthly electric billing data over the years to ascertain billing periods and KW and Kwh consump-tion and to obtain from the ratio Kwh/KW the hours use of peak demand per week, which provides a useful estimate of hours of use for the facility.  Together with minimal faci-lity data (just area data) and daily maximum and minimum outside temperature data, the process identifies patterns of consumption and demand, and then uses conveyance of an empirical analysis to disaggregate biling data into light-ing, power and HVAC end-use categories, and a statistical analysis, including regression, to separate the same bill-ing data into usage and temperature-dependent components.          Proposed retrofits for energy conservation are indicated and then implementable.  Actual savings are calculated and used to further refine the model of actual facility opera-tion.

Title: Side Impact Head Strike Protection System
Inventor: BARK LINDLEY W
IPC: B60R21/231
Filed: 1994-02-16
Abstract: 2118321 9419215 PCTABS00033 The present invention is a tubular structure (11) which inflates upon side or oblique vehicle impact to protect the occupants of a vehicle such as an automobile. The structure is mounted in its undeployed state along the periphery of the vehicle's side pillars (20, 21) and roof rail (23). The primary component of the present invention is a braided tube (15) linked to a gas generator (22). When a side impact is detected, the gas generator (22) is ignited, inflating the braided tube (15). As the braided tube (15) inflates, the diameter of the tube (15) increases and its length decreases. The tube (15) then pulls out of its storage location and forms a taut, semi-rigid structural member across the vehicle's side window (24).

Title: Self regulating centrifugal separator
Inventor: MOHN FRANK
IPC: B04B11/02
Filed: 1992-12-11
Abstract: A centrifugal separator comprises a drum (1) rotatable about its axis within which annular walls (10, 20) define discharge chambers (11, 21) at the ends of the drum, from which separated fluids of different specific gravities are discharged by respective scoops (14, 24). Alternatively, annular walls (44, 45 and 47, 49) define both such chambers at one end only of the drum. The dimensions of the annular walls are chosen so that the separator is self-regulating, in that the separated fluids are discharged independently of the proportions of the fluids in the incoming mixture, so that operation of the separator does not have to be controlled in response to sensing of the separation process within the drum.
Patent CA-2126218-A1 (CA)
Inventor: STOUT GEORGE M
IPC: B24D13/14
Filed: 1992-10-08
Abstract: The present invention provides a backing for a coated abrasive article. The backing of the invention addresses problems of previously known backings for coated abrasives. The backings used previously are typically made of paper, cloth, vulcanized fiber, or combination thereof. Many of these materials do not exhibit sufficient strength, flexibility, impact resistance, and resistance to humidity extremes. High humidity, in particular, may cause premature curling of these backings, rendering the coated abrasive disc inoperable. The backing of the present invention includes a tough, heat resistant, thermoplastic binder material, and an effective amount of a fibrous reinforcing material distributed throughout the thermoplastic binder material. The tough, heat resistant, thermoplastic binder material and the fibrous reinforcing material together form a hardened composition that will not substantilly deform or disintegrate during use.

Title: Apparatus for error-correct decoding in a digital data communications system
Inventor: NOMURA TOSHIYUKI
IPC: H03M13/41
Filed: 1994-08-31
Abstract: In order to effectively error-correct decode a plurality of data frames transmitted over a noisy transmission channel, control data is applied to a maximum-likelihood decoder such as to change decoding parameters thereof.  The control data is generated based on frame characteristic information obtained from at least one data frame which precedes a data frame currently decoded at the maximum-likelihood decoder. Thus, the error-correct decoding is implemented using estimated correlation between at least two consecutive data frames one of which is under error-correct decoding. Further, a cyclic code decoder is provided in a receiver for checking a transmission error in the output of the maximum-likelihood decoder.  The cyclic code decoder issues a check result which is used to change the contents of the control data.

Abstract: The present invention provides a roller shade with a variable load brake and, in a modification thereof with a lift assist. The load brake includes a compressible spring surrounding a threaded rod, the spring acting against a traveling nut mounted on the rod. The compressive friction of the traveling nut against the threads of the threaded rod continually varies during raising and lowering of the shade to provide the variable load braking capability. The lift assist uses at least one torsion spring, also associated with a shaft and coupled between a nonrotating flange and a nipple rotationally anchored to the shaft. The torsion spring system is increasingly loaded when the shade is lowered.
