Title: A method to provide printed and tactile surfaces with a programmable touch response facility for triggering responses
Filed: 2011-11-01
Abstract: An image (4), such as a tactile map, is made interactive by placing the image on a touch sensor panel (5) such as a projected capacitance touch panel. The touch panel is connected to a control circuit such as a computer which is arranged so as to sense touches on the image and may trigger events as may be programmed into the computer. The system may be reprogrammed and updated, over network links where available, thus providing a rapid and cost effective way to manage changes. A typical use would be a tactile map of the locale, where the playback of audio files provides a visually impaired user with access to information such as local facilities, transport services etc. Where the computer is connected to a network, interactive services such as live transport information may also be provided. Inputs and outputs are provided so as to support the attachment of third party systems designed to support the visually impaired.

Title: Electrostatic ink jet printing apparatus and method
Inventor: WARREN W THOMAS
IPC: G06K15/10
Filed: 1980-02-28
Granted: 1985-10-24
Abstract: An electrostatic ink jet printing apparatus and method uses a linear array of nozzles (2) each of which records a segment of a row of pixels in a given raster pattern. The pixel segment is recorded by electrostatically deflecting the ink drops (5) from a nozzle (2) to the pixels contained within the segment. The drops (5) from adjacent nozzles (2) are "stitched" or aligned to these ideal pixel positions by aligning the ink drop streams to drop position sensors (16, 17). Two sensors (16, 17) are used for each nozzle. Preferably, adjacent nozzles share sensors. The sensors are spaced relative to each other to very close tolerances. Consequently, alignment of each nozzle to its two drop position sensors means that the drops from adjacent nozzles are aligned or "stitched".

Title: Tracking control devices for video tape recorders
Inventor: SAITO ISAO
IPC: G11B5/56
Filed: 1982-05-21
Granted: 1985-09-26
Abstract: A tracking control device for a video tape recorder comprises a bimorph leaf on which a rotary playback head is mounted so as to be deflectable in a direction perpendicular to tracks to be scanned. A triangular wave signal generating circuit comprising cascaded flip-flops generates a substantially triangular wave signal which is supplied to the bimorph leaf to cause the playback head to wobble relative to the tracks. A detecting circuit detects an envelope signal in the signal reproduced by the playback head, and a phase comparing circuit which includes an exclusive-OR circuit compares the phase of this envelope signal with the phase of the triangular wave signal. The output of the phase comparing circuit is fed back to the bimorph leaf to effect tracking correction.

Title: Production of pipeline gas from sulfur containing raw or synthesis gas
Inventor: HAPPEL JOHN
IPC: C07C1/04
Filed: 1984-02-20
Granted: 1987-09-03
Abstract: Described is a process for producing methane-rich, pipeline-quality gas from raw gas produced by gasifying carbonaceous materials. Following any needed adjustment of its H2/CO ratio, which can be by a preconditioning water gas shift reaction or its reverse, the raw gas is fed to a direct methanation reaction (2H2 + 2CO-><- CH4 + CO2) which does not require substantial addition of steam. If needed, the intermediate product gas from the direct methanation reaction can be passed over a water gas shift catalyst to control its H2/CO ratio so that after removal of acid gases its methane content can be raised further over a nickel catalyst. This enables production of a very high heating value pipeline gas with only one acid gas removal step in the entire process sequence. In the alternative, the intermediate product gas can be subjected to cryogenic methane separation, with the separated H2 and CO fed back to the direct methanation and the separated methane used as SLNG. A preliminary direct methanation step can be carried out prior to any needed preconditioning step.
