Patent number: 6452503Abstract: A wafer imaging system is provided in which a camera is mounted at a known position in relation to an open front of a cassette to view the cassette and its entire stack of wafer contents. The camera can be mounted on a robot or on a tool. An image of the set of wafers is captured and is image processed to provide information on the position and alignment of each wafer in the cassette. The image can be processed to provide data on separation of the wafers within the cassette, any cross slotting of wafers, and the center point of each of the wafers. Image analysis and processing is employed to determine the edge of each of the wafers. One image scan provides a determination of all information on the X, Y and Z position of the wafers in relation to the camera reference position.Type: GrantFiled: March 15, 2001Date of Patent: September 17, 2002Assignee: PRI Automation, Inc.Inventor: Mitchell Weiss

Patent number: 6448898Abstract: A signaling device is mated with a conventional container to develop a change in state for indicating that the container has been accessed. The change in state can be developed manually, or automatically when the cover of the container is opened, to signal that the container has been accessed, and can be automatically returned to the initial state as part of the procedures used to empty the container. The signaling device is used in combination with a system for auditing a refuse collection process so that subscribers to the service can be charged for service according to usage. This then motivates the subscribers to call for collections of their refuse only from containers that are substantially full, or to compensate the refuse collection service for additional container pick-ups.Type: GrantFiled: September 28, 2001Date of Patent: September 10, 2002Assignee: Cardinal Automation, Inc.Inventor: John P.

Patent number: 6446102Abstract: A method and a device for high-speed scale conversion wherein a value N within a range of N1 and N2 is converted into a small value M within a range of M1 and M2. The method includes the step of obtaining an approximate value of M by loading the value (N−N1+2p−1) into a multi-bit shift register and right-shifting p bits. A binary search process is then used to determine the error value between the actual value of M and the approximate value of M. By avoiding actual multiplication processes, the conversion can be carried out using low-cost electronic hardware such as a microprocessor or a PROM to carry out the binary search process, a shift-register to obtain the approximate value of M, a multiplexer to receive an analog input data N and an A/D converter to convert the analog input data N into a digital data N.Type: GrantFiled: May 21, 1999Date of Patent: September 3, 2002Assignee: Schneider Automation, Inc.Inventors: David L.

Patent number: 6430787Abstract: A design is formed in a carpet secured to a table with a carriage controlled and moved over the table by a computer. A carver is mounted to the carriage and is computer-controlled to carve a design into the secured carpet. Also, a separator is mounted to the carriage and is computer-controlled to separate the carved carpet into a plurality of pieces. The secured carpet has a grain extending in a first particular direction, and carving in a second particular direction produces an actual result offset from an intended result by a quantified offset. The first direction and second directions are determined and a relationship therebetween is calculated. An offset associated with such relationship is then determined, and the determined offset is employed to position a carver during carving in the second direction. Thus, the employed offset produces an actual result that aligns with the intended result.Type: GrantFiled: January 17, 2000Date of Patent: August 13, 2002Assignee: Eagle Automation, Inc.Inventors: Andrew M.
