Title: Robot golf game
Inventor: ROWLAND BRUCE
IPC: A63F7/00
Filed: 1994-05-04
Abstract: The invention includes simulated golf game in which a remotely controlled golfer (64) plays on a miniature course (8).  The course (8) has all the characteristics of a real golf course, e.g., hills, valleys, sand traps, and trees.  The golfer (64) is a model human figure who plays a miniature ball that is free to roll anywhere on the course (8).  The golfer (64) is remotely controlled through an overhead gantry positioning mechanism that connects to the golfer's back by way of a small-diameter rigid tube (60).  The gantry simulates walking by moving the tube (60), with the golfer (64) attached, about the golf course (8).  Animation of the golfer itself is effected by a set of electric motors (28, 54, 65) driving cables (72, 71) running inside the tube (60).  Multiple motors are operated simultaneously to give the golfer (64) a lifelike look.  The motor operations are controlled by a computer (310).  The game can be played by a person with a joystick control (306) that requires skill to manipulate. Alternatively, the computer (310) can play the game by itself by locating the ball's position with the aid of an overhead camera (98).  The computer (310) can also assist the human player to varying degrees to provide the game with beginner and advanced levels of skill.

Patent CA-2164662-A1 (CA)
Title: Adsorption bed regeneration
Inventor: KIEL DARWIN EDWARD
IPC: B01J20/34
Filed: 1995-12-07
Abstract: In the regeneration of hydrocarbon adsorption beds typically the entire bed is heated by hot inert gas flowing continuously through the bed until sufficient hydrocarbons are removed. Desorption rates are often limited by restrictions on the maximum temperature that can be used. Also, in some instances only a portion of the bed may be contaminated and therefore heating the entire bed is both time consuming and costly. The present invention utilizes a combination of strategic positioning of heated zones and vacuum purging to maximize the desorption efficiencies, saving energy, purge gas and time.

Title: Plain surface acoustical product and coating therefor
Inventor: SENSENIG DARRYL L
IPC: G10K11/162
Filed: 1996-08-30
Abstract: This invention describes two products both with a plain, fine textured, nonperforated surface visual consisting of a fiberboard substrate with or without a laminated porous nonwoven scrim and then a finished painted surface. The finished painted surface decorates or finishes the board, but most important, must remain acoustically transparent to retain the sound absorption properties of the fiberboard prior to painting. The fiberboard substrate is made to be porous or modified with hole perforations to cause it to be a good sound absorber. If the fiberboard substrate is sufficiently porous without hole perforations, then the sprayable, high solids, porous paint can be directly applied. If hole perforations are used to improve the sound absorption properties of the board substrate, then a porous, nonwoven scrim is attached and painted using the same high solids porous paint. This painted scrim must be sufficiently optically opaque to hide the hole punched board, yet sufficiently open to render it acoustically transparent. The inventions also include the paint coating alone or the paint/scrim coating alone.

Title: Increasing the capacity of a cellular radio network
Inventor: AALTO RISTO
IPC: H04W36/04
Filed: 1996-10-11
Abstract: The invention relates to a cellular radio network and a method for increasing traffic carrying capacity in a cellular network. The operating frequency spectrum of the cellular network has been divided in such a way that typically both regular frequencies (A, C, F, I) and super-reuse frequencies (S1, S2, S3, S4) are employed in each cell (BTS 1-4). The regular frequencies use a conventional frequency reuse pattern to provide seamless overall coverage (overlay). A very tight frequency reuse pattern is used for the super-reuse frequencies to provide additional capacity (underlay). The cellular network controls the division of traffic into regular and super-reuse frequencies by means of radio resource allocation at the call set-up phase and later on during the call by means of handover procedures. The cellular network monitors continuously the downlink co-channel interference of each super-reuse frequency in the cell separately for each ongoing call.  The call is handed over from a regular frequency to a super-reuse frequency (HO2) when the co-channel interference level on the super-reuse frequency is sufficiently good, When the co-channel interference level on the super-reuse frequency deteriorates, the call is handed over from the super-reuse frequency back to the regular frequency (HO3).

Title: A device for backlighting a liquid crystal panel
Inventor: HOLDEN JOHN
IPC: G02F1/1335
Filed: 1995-11-09
Abstract: A device for backlighting a liquid crystal panel (4) comprises a source (1) of diffuse light, a quarter wave retarder (3), and a circularly polarizing element (2) arranged between the source and the retarder. In operation, diffuse light from the source passes through the circularly polarizing element and then through the retarder, thereby providing un-collimated plane-polarized light for backlighting a liquid crystal display. The device can give the advantage of enabling the use of cheaper, lower quality optical elements and eliminating expensive collimators.
