Title: Photographing apparatus,device and method for obtaining images to be used for creating a three-dimensional model
Inventor: MATSUMURA KOICHI
IPC: G01C11/02
Filed: 2004-05-04
Abstract: This invention introduces, as one aspect, an apparatus for creating three-dimensional object model, comprising photographing means for photographing an object to be modeled for obtaining images to be used for creating the three-dimensional object model, setting means for longitudinally and latitudinally setting a relative position between the object and said photographing means, said setting means being capable of setting the object and said photographing means a plurality of different relative longitudinal and latitudinal positions, and control means for controlling said photographing means and said setting means so that a number of photographs taken from different relative longitudinal positions at a first relative latitudinal position is larger than that taken from different relative longitudinal positions at a second relative latitudinal position, the first relative latitudinal position being closer to a lateral position than the second relative latitudinal position. Accordingly, it becomes possible to minimize the number of photographs for obtaining necessary images to effectively keep a high quality three-dimensional object model, the number of user's manual operations is reduced, and the total photographing time for creating a three-dimensional object model is significantly decreased.

Title: Optoelectronic Assembly, Optoelectronic Module and Method of Aligning Components of the Assembly
Inventor: YI ROBERT H
IPC: G02B6/42
Filed: 2005-11-22
Abstract: In an optoelectronic assembly (10) in which one or more beam paths (24) are to be aligned with a corresponding number of active optical elements (28), the cooperation between flexible alignment features (38; 42, 44 and 46; 62, 64, 66 and 68; and 78) and fixed alignment features (36; 54, 56, 58 and 60; 70, 72, 74 and 76; 80; and 82) achieves elastic averaging so as to provide the target accuracy. By averaging dimensional and positional errors over a large number of localised couplings of the flexible and fixed alignment features, elastic averaging provides the same accuracy as the more costly and complex kinematic alignment techniques.

Title: Dynamically adaptive multi-stage filter
Inventor: LOMAS DAVID
IPC: H03H21/00
Filed: 2006-03-31
Abstract: Radio receivers, such as DAB receivers, require filters which are used to discriminate between wanted radio stations and unwanted (interfering) stations. Close channel frequency spacing places high performance requirements on the selectivity of the radio receiver. However, when using on-chip active filters, increased selectivity requires higher power consumption, but is not necessary for all reception conditions. In the present invention, the order of the selectivity filtering is dynamically selected according to reception conditions, with consequent power savings. This is beneficial to battery life in portable applications. The method involves the measurement of signal level (RSSI) before and after the filter. RSSI measurements are taken as filters of different orders are switched into circuit. The set of measurements is compared with a set of templates to ascertain the correct filter to meet the specification for sensitivity in the presence of adjacent channel interference. The comparison algorithm performs a 2-dimensional search over all combinations of interferer distance and power level. A decision can be made on the basis of rms error.

Title: Clock controlled gating in quantum cryptography apparatus
Inventor: TAPSTER PAUL RICHARD
IPC: H04B10/00
Filed: 2006-07-05
Abstract: A timing and synchronisation apparatus and method for a quantum cryptography system is disclosed. In the receiver, a gating pulse is generated by an electronic clock and synchronised to the receipt of transmitted photons at the detector. This may be achieved by using a phase locked loop to minimize the phase difference between detection of pulses and the gating signal. Once the gating signal has been synchronized with the transmitted pulses in this way the apparatus will only accept photon detection events occurring during the gating period. In one embodiment the synchronization process may involve use of a pseudo-random bit sequence included in a header block of transmitted photon pulses.

Title: Optimizing seismic sensor response by comparing response to a test signal with a reference sensor
Inventor: SCOTT GARY LEE
IPC: G01V13/00
Filed: 2007-01-17
Abstract: A method for correcting response of a seismic sensor (e.g. hydrophone, multicomponent geophone) includes determining a response of the seismic sensor to a test signal 30 (e.g. switched direct current, alternating polarity direct current, current switched or alternated in a sequence such as a pseudo-random binary sequence). A response of a reference sensor to the test signal is also determined 32. The difference between the two responses (e.g. difference in amplitude, frequency, phase or bandwidth) is determined and the response of the seismic sensor to the test signal is adjusted to substantially match the response of the reference sensor to the test signal. If the difference is greater than a selected threshold the seismic sensor is withdrawn from service 34,36. A matching function comprising an inverse filter 38,42 may be used. The reference sensor may be a physical sensor, or may be a numerical model of an ideal sensor. The method may be used for correcting the response of seismic sensors for changes in sensor response over time.

Title: Deletion of Recorded Television Signal after Detection of Credits
Inventor: DODD KEVIN
IPC: G06K9/00
Filed: 2008-08-08
Abstract: A method of deleting a recording of a television signal S6, or displaying a graphical user interface (GUI) to allow a user to decide whether or not to delete the recording (figure 3), when playback of the recording is stopped by the user S3 before the end of the recording and a credits sequence has been detected S4. When the credits sequence has been detected S4 this indicates that the user has watched the entire program, and may therefore want to delete the recording. The credits sequence may be detected by detecting scrolling text, text against a uniform background or text containing certain words e.g. "director", and detection may only occur during a last portion of the recording for example during the last 26% or 15 minutes of the recording. The credits sequence may be detected during reproduction of the recording, or may be detected at some other time e.g. the time at which the recording is stored, in which case the time of the credits sequence is stored and compared with the time of stopping playback.

Title: Computer program and method for producing halftone images
Inventor: CAVE ANDREW WILLIAM PETER
IPC: H04N1/405
Filed: 2009-09-11
Abstract: A computer program for and a method of generating 1-bit image data from multiple-bit image data, by a process which comprises the steps of receiving multiple-bit image data comprising multiple-bit pixel values, deriving from the multiple-bit pixel values 1-bit image data comprising "on" and "off" pixel values, each pixel value of the 1-bit image data corresponding to a pixel of an output medium, which pixel an output device would attempt to mark when printing the 1-bit image data if the pixel value were "on". When printed, the 1-bit image data produces an image constituted by a plurality of densities of dots, the dots being arranged such that, at least for densities of dots greater than first threshold density, at least a majority of dots form a pair with at least one horizontally is or vertically adjacent dot, and for densities of dots less than a second threshold density, the image is substantially free of blocks of 2*2 horizontally and vertically adjacent dots, the second threshold density being greater than the first threshold density. Further embodiments arrange the dots such that, a majority of pairs of horizontally or vertically adjacent dots form a triplet with a horizontally or vertically adjacent dot, instead of ensuring the image is free of blocks of 2*2 horizontally and vertically adjacent dots. The embodiments described seek to achieve improved halftone image appearance having little or no visible graininess or patterning.
