Abstract: An improved frozen product dispenser wherein a product is placed into a cooled hopper and the product is then fed from the hopper into a freezing and dispensing chamber where it is frozen and dispensed.

Abstract: Mask data is analyzed for the presence of a notch. A notch candidate on a polygon boundary of mask data is defined as a plurality of line segments that includes an initial line segment, a final line segment and at least two line segments therebetween. The initial and final line segments define adjacent edges of the notch candidate. A direction of each line segment is a direction of travel from the initial line segment to the final line segment.

Abstract: Mask data is analyzed for the presence of a notch. A notch candidate on a polygon boundary of mask data is defined as a plurality of line segments that includes an initial line segment, a final line segment and at least one line segment therebetween. The initial and final line segments define adjacent edges of the notch candidate and have an angle therebetween within a defined range. A direction of each line segment is a direction of travel from the initial line segment to the final line segment. A plurality of conditions is applied to the plurality of line segments and the direction of travel, and the notch candidate is a notch when all conditions are satisfied. The notch may be removed from the data before mask writing.

Abstract: A petri dish includes a cover and base, the cover having at least one circular opening in the top of the cover. A number of securing members are connected to the underside of the cover around the opening to secure at least one filter under the opening, the filter(s) being used to prevent any contaminants from the air from entering the petri dish. A guard member such as a plastic disc is disposed under the filter(s) to prevent any oil in the base of the petri dish from contaminating the filter(s). A sealing member is provided on a peripheral edge of the base to seal the petri dish when the petri dish is closed.

Abstract: An apparatus that injects fluid into an inflatable device, dynamically monitors the pressure inside the device, and automatically terminates the inflation and disconnects from the inflatable device when the pressure inside the device reaches a predetermined value preset by the operator. After securing a chuck to the valve of an inflatable device by simply pulling a trigger similar to that of a pistol, the operator initiates the inflation and does not need to intervene further.
