  • Patent number: 6999685
    Abstract: A physiological function assisting device 1 is embedded in the body, and is provided with a transmitter 11 and receiver 12 for communicating with an external controller 2. External controller 2 controls embedded physiological function assisting device 1 from the outside. External controller 2 is provided with a transmitter 21 and receiver 22 for communicating with physiological function assisting device 1. Transmitters 11,21 modulate the plane of polarization of laser light, and emit the result as a transmission signal. Receivers 12,22 selectively receive light of a specific polarization state. Receivers 12,22 respectively output electric signals corresponding to the polarization state (polarization angle or ellipticity) of the received light. As a result, full duplex communications between a strongly dispersing medium like the human body and the outside is possible, while the power consumed by the internal device can be reduced.

  • Publication number: 20050248602
    Abstract: In an inkjet deposition apparatus, a print head is translated in a transverse direction relative to a substrate and the deviation of the print head relative to a first alignment mark is measured. The inkjet head is then translated in a longitudinal direction relative to the substrate and the deviation of the print head to a further alignment mark is measured. A correction factor for a control unit for translation stage of the apparatus is then generated from the measured deviations.

  • Publication number: 20050218791
    Abstract: The invention provides a display device (26) including a plurality of discrete display segments (2). Each display segment (2) is provided with a drive circuit for driving the display elements arranged within the display area. The display device may be provided either as a passive, active or direct pixel addressed array. By interconnecting a number of display segments, a large area display can be achieved without the requirement for long electrodes. This reduces the electrical resistance and parasitic capacitance of the addressing electrodes, enabling the display to provide improved luminance in a displayed image and to operate at higher speeds, providing improved resolution. An active matrix addressing scheme can also be implemented using relatively low mobility organic thin film transistors.

  • Publication number: 20050176242
    Abstract: A substrate is patterned by forming an indent region 8 in the surface 10 of a substrate 4 and depositing a liquid material onto the surface 10 at selected locations adjacent to the indent region 8. The liquid material spreads over the surface to an edge of the indent region, at which point further spreading is controlled by the effective enhancement of the contact angle of the liquid material relative to the surface as provided by the indent region.

  • Publication number: 20040235227
    Abstract: A thin film circuit is fabricated using a lithographic technique in combination with an inkjet printing technique. The lithographic technique, providing extremely high resolution, is used to fabricate transistor source and drain electrodes, parts of interconnections and circuit electrodes, enabling highly conductive materials to be used. Semiconductor regions, insulator regions, gate electrodes and other parts of the interconnections, and in particular interconnection cross-over points, are patterned using an inkjet printing technique. A variety of materials can be used in the inkjet printing technique and the alignment concerns associated with the use of multiple lithographic steps and, in particular, with the use of plastics substrates, are substantially alleviated.
