Title: Radio pager
Inventor: ASAI TAKAYUKI
IPC: G08B5/22
Filed: 1991-12-12
Abstract: A radio pager has means for automatically adjusting the rising time of a high-speed clock. The pager includes a plurality of circuit elements for adjusting the rising time i.e. for compensating the degree of stability of a high-speed clock generating circuit 50. On the start of a low-speed clock 30, the high-speed clock generating circuit 50 sequentially selects and connects the circuit elements and counts the resulting rising times of the high-speed clock. The identity of the circuit element giving the shortest rising time is stored. When the high-speed clock is needed, e.g. when a message should be displayed, the identified circuit element is connected to the high-speed clock generating circuit. <IMAGE>

Title: Rolling bearing for a swashplate mechanism
Inventor: NEDER GUNTER
IPC: F16H23/00
Filed: 1992-07-31
Abstract: A rolling bearing for a swashplate mechanism comprises two race rings (10, 12) and rolling bodies (16) disposed therebetween. The rings have raceways (14) on their radially extending surfaces facing each other. The axes (A1, A2) of rotation of the rings are inclined with respect to each other, the rolling bodies being balls (20, 22) of varying sizes. When the ring (12) is driven in rotation about its axis (A2), the assembly of balls (16) also rotates. The ring (10) is held against rotation and performs a wobbling motion in which any one location on the ring reciprocates axially as shown by arrows (24). Instead of the rolling bodies all being spherical the radial dimension thereof may be the same for all but the axial dimensions differ. <IMAGE>

Title: Enhancing the resolution of video cameras
Inventor: KIM SEONG-HUN
IPC: H04N5/225
Filed: 1993-08-09
Abstract: In a video camera, a light collecting lens 10 collects light incident from an object and passes it through an iris 20 to a segmenting mirror 30 which splits the light into two paths. Sequentially operable liquid crystal shutters 40, 41 control the transmission of light through the respective paths, and extending lenses 50, 51 extend the light of each path a number of times. The separate light paths are brought back together by correcting mirrors 32 and 33, and pass to a CCD unit 60, which converts the light signals into separate electrical signals for each path. The separate image path electrical signals are stored in respective memories 64 and 65, and output by an interpolating unit 70 which restores them to a single image signal of the original object, and this signal 15 passed to a signal processing unit 71. In this way, for a given number of pixels of the CCD unit 60, enhanced resolution is obtained, by expansion of each of the separated light paths. <IMAGE>

Title: Music accompaniment apparatus
Inventor: NUMOTO TATSUHIKO
IPC: G10L21/013
Filed: 1993-10-13
Abstract: A music accompaniment apparatus such as a karaoke machine operates in two stages, the first stage being a trial stage in which a video signal is reproduced on a display unit 110 but no sound is generated from a speaker In the trial part, a first pitch detector 103 detects the pitch of the accompaniment read from a recording medium. Such as a laser disc at 101. Meanwhile, a second pitch detector 105 detects the pitch of a singer's voice inputted from a microphone 104. If the pitches detected by the first and second pitch detectors 103, 105 are different, an interval adjusting device 107 changes the key of the accompaniment so as to be in perfect pitch with the singer. Thereafter the medium is rewound and, in the second stage, both video and sound are reproduced from the recording medium, the sound being added at 108 to that from the microphone. The apparatus may alternatively be used to accompany a musical instrument. <IMAGE>

Title: Colour thermal printer having high precision dye donor web positioning
Inventor: TANG MANH
IPC: B41J2/325
Filed: 1995-05-16
Abstract: A thermal printer (10, Fig. 1) includes a web transport (54, 56, 58, 66) for positioning a dye donor web (38) along a path; a sensor (68) along the path and spaced from the print line for detecting the arrival of a leading edge of a dye frame, and a control for the web transport (54, 56, 58, 66). The control is adapted to reposition the dye donor web (38) along the path so that the leading edge of the dye frame is in substantial alignment with the print line before printing the dye frame begins. The web transport (54, 56, 58, 66) moves the dye donor web (38) in both forward and reverse directions past the print line, and the sensor (68) detects the leading edge of a frame while the donor web (38) moves in a forward direction. The control stops the web and reverses it to thereby rewind the dye donor web (38) until the edge of the dye frame is in substantial alignment with the print line. <IMAGE>

Title: Motion vector encoder using spatial majority filter
Inventor: JONES KENNETH STANLEY
IPC: H04N7/36
Filed: 1995-10-03
Abstract: The interleaved sectional combination of an intra-frame spatial majority filter transfer upon scan line interpixel changes is matricised by a fully-compensated interframe change filter in the 'median' temporal-domain to result in a highly effective vector encoder giving exceptional transmission and display resilience to communication noise intrusion in video system distribution, and pixel bit rate or data rate reduction techniques. Purposes include digital video broadcasting and/or HDTV where an attribute change or motion class vector for up-conversion interpolation is derived on down-conversion at picture source for distribution to the destination receiver. The compromise reduction in spatial frequency for pixel vector representation of a scan line is enhanced by the removal of single pixel noise volumes to restore the source encoded signal. The spatial majority vector encoder also has instrumental purpose within video measurement, control, and display systems where the single frame ( DELTA T) delay is not significant. <IMAGE>

The isolating means 27 may be a contactor when the commodity is electricity or a valve when the commodity is water or gas. The arrangement may be used with a prepayment meter to detect and indicate possible fraudulent bypassing of the meter. With regard to an electrical supply, the arrangement may further include means to determine if the phase difference between the input and output voltage signals (Vin, Vout) has dropped below a preset value.
