Title: System and method for occupancy estimation
Inventor: TOMASTIK ROBERT N
IPC: G06F17/18
Filed: 2008-02-26
Abstract: An occupancy estimator calculates an occupancy estimate (x ) of a region based on sensor data (z) provided by one or more sensor devices and a model-based occupancy estimate generated by an occupant traffic model (f). The occupant traffic model (f) is based on predicted movement of occupants throughout a region. The occupancy estimation system includes an occupancy estimator algorithm (20) that combines the sensor data (z) and the model-based occupancy estimate generated by the occupant traffic model (f) to generate an occupancy estimate (x) for the region.

Title: Soft, pelletized poly(vinyl chloride) plastisol
Inventor: HORTON STEPHEN D
IPC: B29C48/41
Filed: 2009-09-08
Abstract: A soft, pelletizable poly(vinyl chloride) plastisol having a Shore A hardness of less than about 70 is disclosed. The plasticizers employed in the plastisol can be petroleum-based plasticizers or bioplasticizers or both. A method of gelation, fusion, and controlled cooling in an agitating chamber permits a conventional liquid plastisol to be transformed into the pelletizable plastisol strand. If a pelletizer is used after cooling into strands or other shapes, then pelletized plastisol results. The formulation of liquid plastisol for hardness is unaffected by the transformation. The solidified plastisol can be stored for later extrusion or molding into a final plastic article shape.

Abstract: A tile-based board game, in the shape of an automobile racetrack. The different tiles in the game represent: the start and finish lines, a curve, the pits, a straight track, an oil patch and a check point. Some tiles have penalties: players landing on curves or the oil patch tiles, must draw a penalty card. Other tiles, like the check point, offer rewards.  Before commencing the game, players choose a race-number, -one through six-.  This race-number rewards prize-money to the players every time the throw of the die shows their particular number. That prize-money is used to buy race-resources:  gasoline, tires and brakes. These race-resources help the players to advance faster and avoid penalties throughout the racetrack. Players begin at the start line tile and by using turns, they throw a single die to advance. First player to reach the finish line, wins.
