Patent number: 6366174Abstract: An improved clock generation circuit is provided that operates with a single input clock frequency, and includes a Phase Locked Loop circuit (PLL) with a digital accumulator in the feedback loop, in which either the Most Significant Bit or the Carry Bit of the binary adder is used as the modulated feedback clock to the phase/frequency detector of the PLL. In one embodiment, a fixed add/phase amount is used to drive one of the inputs of the binary adder to generate a fixed output frequency. If it is desired to modulate the output frequency, then an Add Amount Modulator circuit can be provided that presents a varying numeric value to one of the inputs of the binary adder. The MSB or Carry Bit is communicated to an address look-up table, which then outputs an address to a memory circuit, which in turn presents a different add amount to the binary adder.Type: GrantFiled: February 21, 2000Date of Patent: April 2, 2002Assignee: Lexmark International, Inc.Inventors: John B.

Patent number: 5406468Abstract: In a power supply that includes switch-mode feedback, output transient responses can be minimized by first detecting a predetermined load change. Once the load change has been detected, the switch-mode feedback is adjusted for a predetermined period of time to a maximum level for load increases or to a minimum level for load decreases. When the predetermined period of time elapses, the switch-mode feedback is adjusted to an output voltage dependent mode of operation.Type: GrantFiled: September 2, 1993Date of Patent: April 11, 1995Assignee: Motorola, Inc.Inventor: James R.

Patent number: 5239627Abstract: A parallel interface connects a data processor and a printer so that each may transmit information to the other or receive information from the other. The transmitted information from the data processor can be data or status signals. The data or status signals are transmitted over the same eight information lines between the data processor and the printer with a predetermined signal being sent over another line from the data processor to the printer prior to transmission over the eight lines to identify whether the transmitted information is data or status signals. The printer sends status signals to the data processor over the same eight information lines after sending a predetermined signal to the data processor over a further line that it is going to transmit.Type: GrantFiled: March 26, 1991Date of Patent: August 24, 1993Assignee: International Business Machines CorporationInventors: James L. Beck, James R. Booth, James C. Buchanan, Margaret E. Claffey-Cohen, Carl P. Cole, Timothy J. Louie, Alan F. Neel, II, Lynn M. Oliver, James P., Ward, James F. Webb

Patent number: 5146547Abstract: A page printer (101) which rasterizes a page utilizing partial page bit map swaths. Received data to be printed is stored in packets (12-17) in a page buffer in random access memory (105). Data within each packet is arranged in printing order down the page to be printed, but the packets themselves are arranged in the order received, and are not indexed or linked. As each swath (11) is rasterized, each packet is examined, and packets containing data falling at least in part within the active swath are processed. The printer is controlled by a programmed microprocessor, and logic hardware assistance is provided for translating data addresses from logical addresses (54) to physical addresses (52). Logic hardware assistance is also provided for making the determination of whether or not a given data address lies within the active swath.Type: GrantFiled: November 7, 1991Date of Patent: September 8, 1992Assignee: Lexmark International, Inc.Inventors: James L.
