  • Publication number: 20080123128
    Abstract: The present disclosure relates to a method and/or apparatus for determining whether to select media for printing. This may be accomplished by identifying a media signature present in the media and identifying a data stream signature that may be printed on the media. A comparison may then be made as between the data stream signature and the media signature. Based upon the comparison media may then be selected for printing.

  • Publication number: 20080055610
    Abstract: Systems and methods for marking media are provided. The method may include preparing an image for printing on print media, the image including an indication of a first and a second event. The method may further include printing a first portion of the image on the print media, evaluating data and electing to print a second portion of the image wherein the second portion includes the indication of either of the first or second event.

  • Patent number: 7261478
    Abstract: A printing device (10) such as a laser printer includes a radio frequency controller (38) which permits the detection and redirection of media having one or more defective radio frequency device tags, such as an RFID tag, to a specific one of two or more output options (50, 52). The radio frequency controller (38) may include radio frequency control logic (500) that communicates with the base printer (10) and the output options (50, 52) over a down port (506) and up port (508) to intercept commands from the printer (10) to the options (50, 52) and to also respond to such commands. A defective tag can be detected by attempting to program a tag using an RF reader/programmer (504).

  • Patent number: 7249819
    Abstract: The presence of a radio frequency signature (88) on a cut sheet of print media (28) is detected by a radio frequency interrogating device (94) to determine it's relative left/right position on the print media (28). Either the leading edge (124) or trailing edge (126) of the print media (28) is detected by one or more print media sensors (86, 90). A print controller (24) can note the time (t1) when print media is detected and cause the radio frequency interrogating device (94) to detect the radio frequency signature (88) at a time (t2) when the print media has reached a predetermined point along the print media pathway (110). The position of the radio frequency signature (88) on the print media (28) can be calculated using the time differential (t2-t1) and the known angular displacement of the radio frequency interrogating device (94).

  • Patent number: 7223030
    Abstract: A printing system (250) includes a printing subsystem (255) in the form of a printer assembly (14). The printing subsystem (255) includes a printer housing (257) in which a print engine (259) resides and a memory (261) for storing data indicating the position of labels on media. The contents of memory (261) can be obtained from an end user application (270) which may supply the position data to the printing subsystem (255) in a print data stream. Pre-programmed position data is read from a tag (88) on print media (28) having multiple tags embedded thereon. The pre-programmed position data is compared to position data received in a print request data stream to determine the position of at least one tag on the print media.

  • Patent number: 7187294
    Abstract: A radio frequency signature (88) on a cut sheet of print media (28) is detected by a radio frequency interrogating device (94) to determine whether the print media (28) is properly oriented. The leading edge (124) or trailing edge (126) of the print media (28) is detected by one or more print media sensors (86, 90). A print controller (24) can note the time (t1) and cause the radio frequency interrogating device (94) to detect the radio frequency signature (88) at a time (t2) when the print media has reached a predetermined point along the print media pathway (110). The position of the radio frequency signature (88) on the print media (28) can be calculated using the time differential (t2?t1), the velocity profile of the print media and the known separation between the print media (28) and the radio frequency signature (88). By comparing the computer position with the expected position, the orientation of the print media (28) can be determined.

  • Publication number: 20060074066
    Abstract: This invention is directed to the use of an inhibitor of cathepsin-S or -B, or composition thereof, to treat or prevent chronic obstruction pulmonary disease, or physiological condition associated therewith. Such a therapy would occur using at least one of such inhibitors alone or in combination with the other, or further in combination with an anti-inflammatory agent.

  • Patent number: 7012390
    Abstract: An improved variable speed fan controller for use in devices such as laser printers. The controller automatically adjusts its output signal to fans such that a fan quickly settles into an appropriate operating speed, even if the fan has been newly installed into the equipment. The controller can store values in non-volatile memory, if desired, to keep track of recent changes in the fan's operating parameters and corresponding control signal values. The controller is able to control relatively inexpensive fans that don't necessarily operate at a predictable fan rotating speed under repeatable conditions and control signals, by controlling the fan to an initial or predetermined rotating speed; if the fan isn't running within a suitable range of rotational speeds, then determining whether a fine or coarse adjustment should be made to the fan's rotational speed. The controller makes appropriate adjustments until the fan's rotational speed is within acceptable operating tolerances.

  • Patent number: 6978997
    Abstract: Control (P) of imaging device (1) senses the period of time sensor (17) senses media (5) at input feed roller (16a). When a too-long-over-sensor condition is sensed, drive of input feed roller (16a) is terminated by operation of clutch (C). A feed roller (19a) farther in the media path continue to operate. One sheet of media (5) is fed while a dual fed sheet is held in the nip of feed roller (16a) and idle roller (16b). Subsequently, feed roller (16a) is again driven to feed the dual fed sheet for normal imaging.

  • Publication number: 20050001610
    Abstract: An auto-ranging electricity meter circuit having multiple current signal paths. Each of the current signal paths are amplified by a different amount of gain, and then applied to an ADC. The ADC then converts each of the amplified signals at different gains in a continuous process. The system analyzes the different sets of samples to determine which is the most accurate to use. Advantages of an embodiment of the present invention include improved accuracy of an electricity meter using a lower cost AMD converter.
