Title: Clock Recovery Method and Apparatus in a Diversity Receiver
Inventor: KAZECKI HENRY L
IPC: H04L7/04
Filed: 1993-02-26
Abstract: A diversity receiver (200) recovers clock information from different versions (301, 302) of a transmitted signal (106). The diversity receiver (200) receives the different version (301, 302), converts the versions (301, 302) into samples (307, 317) via a common sampling clock (309). The receiver (200) the correlates the samples (307, 317) with like synchronization patterns and uses clock information from the received version (307 or 317) which gives the greatest correlation output signal (504,506) for data detection in one of two detectors (323, 326). The choice of detectors (323, 326) is determined by the diversity receiver (200) by counting the total number of bit-differences output by detectors (323, 326) over a predetermined time period and comparing the total bit-differences with a number represented by a threshold signal (330).

Title: Process for recovering organic components from liquid streams
Inventor: BAKER RICHARD W
IPC: B01D17/02
Filed: 1992-06-19
Abstract: A separation process for recovering organic components from liquid streams. The process is a combination of pervaporation and decantation. The liquid stream to be treated (501) contains at least two organic compounds. A first decantation step (502) is used to remove an organic product phase (503), and the residue (504) from the decanter is then treated by a pervaporation step (505). The pervaporation step (505) is used to concentrate the remaining organic to a point above the solubility limit, so that a permeate stream (507) that will phase separate is formed. The condensed permeate stream (509) is then passed to a second decantation step (510). The aqueous stream (511) from the second decanter is returned to the pervaporation step (505). A system for performing the above steps on a three component feed stream (501) is also disclosed. The system includes a first decanter (502), a pervaporation unit (505) and a second decanter (510).

Title: Exercise apparatus and method of operating exercise apparatus
Inventor: RAWLS R LEE
IPC: A63B21/002
Filed: 1994-03-08
Abstract: An exercise apparatus having a vertically movable weight, and an input pedal mechanism engaged by the user to input an input power with a unidirectional exercise force at a user-selected velocity for moving the weight upward. Also included is a brake applying a negative braking power with a unidirectional braking force opposing the exercise force. The braking power has a braking velocity for permitting downward movement of the weight. A brake controller controls the application of the brake to maintain the braking velocity at a selected constant velocity for at least a selected portion of the user's exercise time. A differential member is coupled to the weight and receives the input power and the braking power. The differential member determines a differential between the user-selected velocity and the selected constant braking velocity, and applies the resultant to movement of the weight. If the user-selected velocity is greater than the braking velocity, the weight is lifted, and if the user-selected velocity is less than the selected constant braking velocity, the weight is lowered. If they match, the weight is maintained in a stationary elevated position.

Patent CA-2118781-A1 (CA)
Inventor: AYASH BASEM A
IPC: G06F13/24
Filed: 1994-03-10
Abstract: A system management mode address correction system for a computer provides correct address values on the address bus when the computer is in system management mode.  Conventionally, bit 20 of the microprocessor's address outputs may be  masked by asserting the FORCE A20 signal.  The computer system also operates in a system management mode, which requires all of the address bits to be available for proper access to the system management interrupt vector.  When the computer is in system management mode, the computer's microprocessor asserts a system management interrupt active (SMIACT*) signal.  This signal is provided to a circuit which also receives the FORCE A20 signal. While the SMIACT signal is deactivated, the control circuit provides the true FORCE A20 signal to the computer system.  When an SMI occurs, the SMIACT signal is activated and the FORCE A20 signal is disabled.  As a result, the address generated by the microprocessor is asserted on the address bus.

Title: Tessellation system
Inventor: PETERSON JOHN
IPC: G06T19/00
Filed: 1994-01-06
Abstract: The present invention provides a method and apparatus for tessellating three-dimensional spline surfaces, which are separated into columns having a series of subpatches, into shards. This is accomplished by undertaking a series of evaluations upon each of the subpatches of a selected column. The intermediate results of such evaluations are stored within caches. Such evaluations include continuity between subpatches, visibility of subpatches and granularity for discretization of the subpatches. Once the evaluations are completed, a grid which holds the discretized points of each subpatch, is computed by dynamic selection of an algorithm.  Thereafter, any crack between subpatches of the selected column or the selected column and the previously selected column are removed.  Ultimately, the previously selected column is rendered for illustration. Each of the columns is handled in the same manner so as to ultimately render a set of adjacent columns that form the two-dimensional representation.
