Patent number: 7768219Abstract: A device controller system incorporates an inexpensive Hall element to detect motion of a brushless DC motor. A magnet, which is part of a motor rotor, passes by the Hall element producing a Hall voltage each rotation. The Hall voltage is coupled through an interface port to a comparator within a process controller. A microprocessor within the process controller calculates a control response based on a comparator output signal. The interface port is rapidly configured to provide signals produced from the control response as output to device drivers on the same input-output pins that receive the Hall voltage. The device drivers produce a current through fan coils producing an update in the magnetic field of each motor phase which updates the speed of the fan according to programming within the process controller. Rapid configuring and reconfiguring of the interface port allows all necessary components of the controller system to be used with a single rotational commutation cycle.Type: GrantFiled: August 19, 2008Date of Patent: August 3, 2010Assignee: Atmel CorporationInventor: Marvin L.

Publication number: 20080272720Abstract: A method of and system for controlling a brushless direct current (BLDC) motor includes providing with a lookup table a predetermined corresponding desired revolution time (DRT) for the BLDC motor for an ambient temperature. A Hall device is used to measure an actual revolution time (RT) of the BLDC motor. DRT and RT are compared to change duration of a pulse width modulation (PWM) signal in response to the comparison result. The PWM signal is applied to one of two BLDC motor windings.Type: ApplicationFiled: May 3, 2007Publication date: November 6, 2008Applicant: ATMEL CORPORATIONInventor: Marvin L. Kausch

Patent number: 4954970Abstract: A predominatly hardware-based system for rapidly generating overlay images by painting techniques using a host computer with appropriate graphics-generation operator interface, and for manipulating overlay images with respect to a background image. The system provides for rapid, convenient control of such imaging aspects as color alteration, repositioning the overlays on the background, and predetermining the amount of mask protection to be associated with each image pixel. The system can be readily realized, using available integrated crcuits, in the form of a host-computer plug-in accessory. A bidirectional multiple bus structure serves to interconnect the circuit boards, permitting convenient host-software-controlled configuration of the system.Type: GrantFiled: April 8, 1988Date of Patent: September 4, 1990Inventors: James T. Walker, Marvin L. Kausch

Patent number: 4677574Abstract: Edge data is stored in a bit map, and clocked out pixel by pixel to form a pixel data stream for display. The edge data defines the regions or faces in the display image which have the same color. The face edges form transitions in the data stream (0-to-1 or 1-to-0), and are detected by an edge detector for generating sequential color addresses. The color data for each face is stored in a color memory in the order of appearance, and is accessed at each edge transition when a color change is required. The color address associated with each edge transition accesses the color for that face from the color memory. Each pixel in the display has a corresponding bit in the pixel map; and each color change in the display has a location in the color memory. The pixel data is sequentially accessed from the pixel memory by the pixel clock. The color data is sequentially accessed by the pixel transitions and synchronized into the display at each face edge.Type: GrantFiled: August 20, 1984Date of Patent: June 30, 1987Assignee: Cromemco, Inc.Inventor: Marvin L.

Patent number: 4407536Abstract: The door on an environmental chamber is provided with a single throw, multi-fingered over-center latching mechanism. The latching fingers extend from a common pivoting assembly, and are operated as a unit by a single handle. A hook on the end of each finger engages a post on the chamber housing. As the handle is operated, the over-center action of the pivoting assembly pulls the door towards the housing causing the gasket to seat. The over-center structure biases the latching mechanism in the latched position.Type: GrantFiled: February 17, 1981Date of Patent: October 4, 1983Assignee: Cromemco Inc.Inventor: Marvin L. Kausch

Patent number: 4259843Abstract: The isolation chamber has an aluminum outer housing with heat transfer fins extending therefrom on the outside vertical surfaces, and insulation material mounted along each inside surface thereof forming a thermally insulative shell. Large aluminum studs extend inwardly from the side surfaces of the housing through the insulative shell for supporting a solid state heat pump. Each pump has a set of inwardly directed heat exchange fins. Each stud and associated pump and inwardly directed set of fins forms a heat conductive path between the surrounding ambient air and the interior of the isolation chamber for controlling the heat flow therebetween. The combined configuration of the inner heat exchange fins defines a central cavity which is temperature controlled to within a desired operating temperature range. A card cage containing the electronic devices is installed in the temperature regulated central region.Type: GrantFiled: October 9, 1979Date of Patent: April 7, 1981Assignee: Cromemco Inc.Inventor: Marvin L.
