Patent number: 5469532Abstract: A host computer and printer and method of operation wherein the data file describing a document is processed in a manner that creates a frame of data to be transmitted from the host computer to the printer. The data frame contains a data stream which is wrapped in a create font command wrapper so that the printer will be able to process the data frame in some manner. If the printer is operating in a first mode and cannot process the actual stream data, the frame wrapper will allow the printer to process the wrapper and ignore the data stream. If the printer is operating in a second mode and can process the actual data stream, the printer ignores the wrapper and processes the data. The printer will print a message to the user if the printer cannot process the actual data stream. The message informs the user of the printer's inability to process the data stream.Type: GrantFiled: November 16, 1992Date of Patent: November 21, 1995Assignee: Microsoft CorporationInventors: Brett C. Gerlach, Patrick Lee, William B. McCormick, George H. Douglas

Patent number: 5467435Abstract: A host computer and printer and method of operation wherein the printer is able to switch between two modes of operation. When the printer is powered up, it initializes its internal data registers and printer memory, followed by a check to see if additional firmware, in the form of a cartridge or the like, is added to the printer. If additional firmware is present, the printer turns operational command over to the additional firmware. The present invention, residing in the additional firmware, stores a complete image of the printer state, internal registers, and memory in a location that cannot be accessed by either mode of operation. The present invention compresses the data so that the complete image of the printer state, internal registers, and memory occupies approximately eight KBytes of memory. The storage location may be part of the printer memory itself, or any other suitable location.Type: GrantFiled: November 16, 1992Date of Patent: November 14, 1995Assignee: Microsoft CorporationInventors: George H. Douglas, William B. McCormick, Stephen V. Dennis

Patent number: 5052934Abstract: Apparatus is provided to serve as a phantom for evaluation of prosthetic valves and cardiac ultrasound procedures, wherein a controlled pulsatile flow of a blood-mimicking fluid is passed through a multi-chambered region into which are mounted mitral and aortic valves and adjustably positionable ultrasound transducers. A low friction, drive which involves very low levels of extraneous vibrational inputs, is provided with adjustment of both the volume flow rate of blood-mimicking fluid moved in each operational pulse with further control provided by relatively easily adjusted screws to selectively regulate the systolic and diastolic times of the pulsatile flow generated by a bellows arrangement. Windows made of silicone elastomer material presenting both tissue-equivalent impedance for ultrasound transmission and tissue-equivalent attenuation of the ultrasound are provided in controlled thickness to permit detailed observation of valvular flow parameters of interest, e.g.Type: GrantFiled: April 20, 1990Date of Patent: October 1, 1991Assignee: The United States of America as represented by the Department of Health and Human ServicesInventors: Ronald F.

Patent number: 4694405Abstract: The laser printer controller for accepting a page of data to be printed in ASCII character format converts the data into a dot-by-dot character pattern for packing in a vertically scrolling partial page bit map. The alignment device within the laser printer controller provides the means for effectively aligning the randomly positioned dot-by-dot character patterns having a first word orientation with respect to its storage boundaries with a second word orientation necessitated by the fixed word storage boundaries of the partial page bit map. The alignment device includes means for partitioning two adjacent words in their first word orientation of the character pattern for alignment with the second word orientation of the page bit map, packing the two respective portions of the adjacent words into a one word format, rotating or manipulating the two word portions within the one word format for proper bit sequence for a single print data word of the second word orientation.Type: GrantFiled: July 9, 1985Date of Patent: September 15, 1987Assignee: Office Automation Systems, Inc.Inventors: Colin Bradbury, George H. Douglas
