  • Patent number: 10460624
    Abstract: A system and method enables production of medicament containers with edible material at a site for dispensing medicaments. The containers are formed in shapes that indicate the contents of the containers and can be formed with indicia that indicate the times for taking the medicaments. Additionally, the containers can be formed with raised protuberances that provide information regarding the medicaments in the containers. In one embodiment, the raised protuberances are in Braille.

  • Patent number: 9400473
    Abstract: A media supply device includes a tray feeding printable media into a printing device. The tray has a first section sized for a first size of printable media and a second section sized for a second size of printable media. The first section is within the second section. The tray has a base with a first end and a second end. A first endwall is perpendicularly connected to the first end of the base. A second endwall is perpendicularly connected to the second end of the base. Sidewalls having a top edge are connected to edges of the base between the first endwall and the second endwall. The top edge of the sidewalls is a first height above the base in the first section and a second height above the base in the second section. The first and second heights are different.

  • Patent number: 8724130
    Abstract: Methods and systems monitor the activity usage level of a printing apparatus and place the printing apparatus into a power saving mode based on the activity usage level. Such methods and systems sense whether the power supply is to be disconnected from the graphic user interface based on the printing device going into the power saving mode. The graphical user interface comprises a bistable display that continues to show a most recently provided screenshot after the power supply is disconnected. Such methods and systems cause the graphic user interface to display power saving mode information of the printing apparatus (instructions for a user to take to have the printing apparatus leave power saving mode) immediately prior to the power supply being disconnected from the graphic user interface, such that the graphic user interface continues to display the power saving mode information after being disconnected from the power supply.

  • Patent number: 7893680
    Abstract: A circuit and method for generating an electrical alternating current power signal in which the alternating current signal is dropped once at a non-zero crossing point in every 540 plus N degrees, where N is a non-negative number. This manner of controlling power to a device enables wide ranges of power control while generating acceptable levels of power line harmonics and while conforming to existing international regulations governing voltage variations.

  • Patent number: 7861165
    Abstract: A printing apparatus and method for capturing and formatting the content of a web page. The apparatus and method determining if a portrait formatted representation of the web page and a landscape formatted representation of the web page, include equivalent content, and outputting the portrait formatted representation of the web page if the portrait formatted representation has the equivalent content of the landscape formatted representation. Otherwise outputting a landscape formatted representation of the said web page.

  • Patent number: 7330675
    Abstract: A fusing apparatus for xerographic printing includes two lamps therein. There is applied to the first lamp a first wave set and to the second lamp a second wave set, each wave set comprising a predetermined arrangement of active half-cycles for each time period. The first wave set and second wave set are related to substantially minimize simultaneous active half-cycles in each time period.

  • Patent number: 6819445
    Abstract: A printing system, available to a population of users on a network, checks whether files in recently-received print jobs are identical to files which have been previously decomposed or rasterized within a particular time frame prior to the submission of the job. If it is detected that a file to be printed in a recently-submitted job is identical to a file which has already been rasterized with the rasterized image available in memory, the system substitutes the already-rasterized file for the file submitted with the job, thus saving the time and resources for rasterizing the file in the recently-submitted job.

  • Patent number: 6522431
    Abstract: In a document handler associated with a scanner, such as for a digital copier or facsimile machine, an image-bearing sheet is moved over a window, through which the image is recorded by a photosensitive chip. When a spot of dirt attaches to the window, a streak results in the image data. This streaking problem is minimized by having the scan line viewed by the photosensitive chip move a small distance within the window of the document handler, so that any spot on the window will not be repeatedly exposed by the photosensitive chip.

  • Publication number: 20020075506
    Abstract: A digital printer which resides on a network is, by itself, capable of accessing an electronic mail account which exists in an SMTP server on the same network. The user interface of the printer can be used to enter a network password and view headings of messages in the account associated with the network password. The user can then request the text or attachments of certain messages to be output at the printer. The system allows any user who has access to the network to retrieve electronic mail without a personal computer.

  • Patent number: 6393161
    Abstract: In a document handler associated with an input scanner, such as for a digital copier or facsimile machine, an image-bearing sheet is moved over a relatively narrow window, through which the image is recorded by a photosensitive chip. When a spot of dirt attaches to the window, a streak results in the image data. This streaking problem is addressed by detecting image data consistent with such a streak, and applying a suitable correction algorithm to the image data. The suitable algorithm is chosen based on the thickness of the streak and the nature of the image data.

  • Patent number: 5272509
    Abstract: The invention relates to a liquid dispensing apparatus suitable for use in the fuser of an electrostatographic recording machine such as, for example, a xerographic copier or a printer. The apparatus includes a trough (41), a wick (100) extending along its length and a roller (47) in contact with the wick (100). A metering blade (49) is located adjacent the roller (47) in such a manner as to scrape off excess liquid from the surface of the roller (47), the metering blade (49) being disposed relative to the wick (100) such that the excess liquid falls on the wick (100) thereby ensuring saturation of the wick (100). Return paths for the excess liquid are provided between the wick (100) and the wall of the trough (41) so as to prevent build up of the excess liquid above the wick (100).
