Publication number: 20110157291Abstract: A thermal printhead includes a substrate, a nonconductive coating over the substrate, a number of heating elements disposed on the substrate, and one or more resistors at least partially disposed within the nonconductive coating. The heating elements cause thermochromic media to selectively darken in accordance with selective activation of the heating elements as the media moves in relation to the thermal printhead, to print a desired image on the media. The nonconductive coating protects the heating elements and wears away with usage of the printhead. The media comes into contact with the nonconductive coating during printing of the desired image on the media. The resistors indicate wear of the thermal printhead, and have electrical resistances that increase as the resistors are worn away in accordance with wearing away of the nonconductive coating.Type: ApplicationFiled: December 24, 2009Publication date: June 30, 2011Inventors: Timothy W. Crockett, Stacy L. Arrington

Publication number: 20100142795Abstract: Method, computer program product, and apparatus are provided for identifying a graphic symbol within an image obtained by optical scanning. An image intensity is measured for each of a plurality of columns of the image, wherein each column has a length that extends across the graphic symbol in a first direction, and wherein the plurality of columns collectively extend across the graphic symbol in a second direction. The graphic symbol is then identified by matching a profile of the image intensity to a predetermined image intensity profile associated with a given graphic symbol. Optionally, the image is a digital image and the image intensity for each column is the sum of the image intensity for each pixel in that individual column. An image intensity differential between adjacent columns may be calculated for matching with a predetermined differential profile or comparison with an electronic profile generated by a magnetic scan.Type: ApplicationFiled: December 9, 2008Publication date: June 10, 2010Applicant: International Business Machines CorporationInventor: Timothy W.

Patent number: 7492358Abstract: An improved resistive touch panel is disclosed. The improved resistive touch panel includes a first plurality of stripes of a resistive coating on a front sheet running in a first direction and a second plurality of stripes of a resistive coating on a back sheet running in a second direction. The overlapping regions between the first and second plurality of stripes are scanned by a controller circuit to detect voltage drops at these regions. Because the overlapping regions are independent of each other, the controller circuit is able to detect the individual regions involved in the touch area. In this manner, the controller circuit is able to determine between small and large areas of contact by detecting adjacent contact areas.Type: GrantFiled: June 15, 2004Date of Patent: February 17, 2009Assignee: International Business Machines CorporationInventors: Hye S. Chi, Timothy W. Crockett, Albert V. Makley

Patent number: 7464594Abstract: A method for sensing paper on a paper roll is disclosed. The method comprises transmitting an ultrasonic signal into the paper roll and detecting an ultrasonic return echo transmit signal from the paper roll, the ultrasonic return echo transmit signal resulting from the ultrasonic signal interacting with the paper roll. Moreover, the method comprises determining an amount of paper remaining on the paper roll in response to the ultrasonic return echo transmit signal. Furthermore, the method may comprise indicating that the paper roll needs to be replaced in response to determining the amount of paper remaining on the paper roll.Type: GrantFiled: September 21, 2006Date of Patent: December 16, 2008Assignee: International Business Machines CorporationInventors: Robert T. Cato, Timothy W. Crockett, Richard H. Harris, Jeff D. Thomas

Publication number: 20080252619Abstract: A system for providing a touch interface on a display are described. The system include providing an emitter on a first side of the display and providing a detector on a second side of the display. The emitter provides an electromagnetic signal to the display. The electromagnetic signal has a path from the emitter to the detector through the display in the absence of a user's touch such that the electromagnetic signal is detected by the detector in the absence of the user's touch. The path includes at least one total internal reflection in the display. The emitter and the detector are configured such that the user's touch at any of the at least one total internal reflection alters the path such that a portion of the electromagnetic signal does not reach the detector.Type: ApplicationFiled: May 8, 2008Publication date: October 16, 2008Applicant: International Business Machines CorporationInventors: Timothy W.

Patent number: 7224344Abstract: An apparatus for use in kiosks or other computerized devices for filtering out selected key codes transmitted between an input device, such as a keyboard, and a host computer. The apparatus includes an input port to receive key codes transmitted from a keyboard en route to a host computer or workstation. A key code filter may be used to filter out or block selected key codes, sequences of key codes, and combinations of key codes, and to prevent unauthorized persons from accessing certain functions of the host computer. Key codes blocked or filtered out may be modified in accordance with each particular system. Once selected key codes are filtered out, an output port passes the remaining unblocked key codes to a host computer.Type: GrantFiled: August 5, 2003Date of Patent: May 29, 2007Assignee: International Business Machines CorporationInventors: Timothy W.
