  • Patent number: 7187908
    Abstract: A user can easily identify the content of data (the value or the state of the data), such as a credit balance, stored in a contactless IC module provided in a wrist-watch device having a communication function. A timepiece control unit 14 of a timepiece module 10 transmits a confirmation command for the data, such as the credit balance, to a contactless IC module 60 every determination cycle period TSP, and receives the data stored in the contactless IC module 60. When the value of the stored data (for example, the amount of balance) becomes smaller than a predetermined value, the timepiece control unit 14 causes a second hand to perform an irregular movement noticeably different from the regular timing movement. Accordingly, the user is able to easily identify the data content (for example, insufficient balance).

  • Patent number: 7170502
    Abstract: A method for creating an ink-trail and implementing a partial ink layer in a pen based computing apparatus is described. The partial ink layer, which is smaller than a display window of a computing apparatus, is located at a starting address with a shape and size that fits within the display widow. An ink trail is created within the ink layer that simulates ink flowing from the pen to paper while a character, or several cursive characters, is formed by the pen while touching a touch screen overlaying the display screen of the computing apparatus. The ink trail is erased when the pen is removed from the touch screen. The bit depth of the pixels in the partial ink layer are less than for the pixels of the main display and can be as few as 2, which includes a transparency bit.

  • Patent number: 7159128
    Abstract: The invention is directed to a method and apparatus for selectively reducing the depth of digital data. Multiple bit digital data is transmitted to a data receiving device on a plurality of data output lines. Each data output line corresponds, respectively, to a unique one of the bits of the data. A determination is made whether, in the data receiving device, a power saving mode of operation of the device is to be initiated. If so, one or more of the data output lines are selected as non-transmitting data lines, one or more remaining data input lines are driven with corresponding bits of the data, and the non-receiving data lines are placed in a neutral state.

  • Patent number: 7083344
    Abstract: In a label printer in which either a peeling mode or non-peeling mode can be selected as the label dispensing mode, labels are printed and thus wasted when the operator loads the label paper into a transportation path that does not match the desired dispensing mode. This problem is solved by a label printer enabling selecting as the printing configuration either a peeling configuration for peeling printed labels from the web of label paper 11, or a non-peeling configuration in which the printed labels are not separated from the web of the label paper 11. A printing configuration selection unit 27 enables selecting which printing configuration to use. To operate in the non-peeling mode, the label paper 11 is loaded into a first paper transportation path A. To operate in the peeling mode, the label paper 11 is loaded to a second paper transportation path B. A cover unit 2 can be opened and closed to enable handling the label paper, and takes the label printer off-line when the cover unit 2 is opened.

The state machine stores the data returned from the slave in response to the first request in the register at a second time. The state machine receives a second request from the host for data stored at a second address in the slave at a third time. The state machine provides the data specified in the first request to the host at a fourth time. The state machine is additionally adapted to provide data to the host from a second address in the slave in one read cycle.

  • Patent number: 7046227
    Abstract: A system and method for continuously tracing transfer rectangles for performing image data transfers includes a display controller with control logic, a rectangle module, and a coordinates module. The rectangle module detects write operations to on-screen data in a video memory, and then updates a primary transfer rectangle during a normal mode to include pixel data from the foregoing write operations. The coordinates module stores the primary transfer rectangle for performing a current transfer operation. The coordinates module enters a pause mode before initiating the current transfer operation, and retains the primary transfer rectangle during the pause mode. The coordinate module also stores a secondary transfer rectangle formed during the pause mode by detecting the foregoing write operations. The controller logic instructs the coordinates module to resume the normal mode after the current transfer operation concludes.
