Patent GB-2275780-A (GB)
Title: Determination of Zinc Phosphate
Inventor: KAWASAKI ISAO
IPC: C23C22/77
Filed: 1994-02-10
Abstract: The activity of a zinc phosphate treatment solution, containing a complex hydrofluoric acid, for forming a phosphate coating on an aluminium surface, is measured by adding a prescribed amount of simple fluoride and evaluating the activity of the solution by measuring the concentration of HF using a silicon electrode meter. The simple fluoride reacts with the aluminium salt of the complex acid and the amount of simple fluoride left gives an indication of the activity of the phosphate solution. The test solution should have a pH of 2 and added fluoride to give an HF concentration of 200 to 500 ppm. The presence of small amounts of simple fluorides e.g. >/= 50 ppm, does not invalidate the test. The simple fluoride is exemplified by HF, NaF, NaHF2, KF, KHF2, NH4F and NH4HF2. The complex hydrofluoric acid may be H2SiF6 or HBF4. The addition of the simple fluoride also reactivates the phosphate solution.

Patent GB-2289814-A (GB)
Title: Laser doppler velocimeter
Inventor: ROSS MICHAEL MCLEAN
IPC: G01S17/58
Filed: 1994-05-06
Abstract: In an improved LDV laser beams A, B inclined to each other are directed to separate (but adjacent) locations on the target 3. Doppler shift of the two beams A, B is extracted, preferably by comparison with respective reference beams, and the velocity is determined from the difference of the Doppler shifts. Pedestal frequencies, i.e. frequency shifts in the reference beams, are preferably incorporated into each comparison to make the velocity determination unambiguous. Modifications of this system use a single laser and an acousto-optic cell (Fig 4, 5) to produce both beams, with and without the pedestal frequency and with and without the reference frequence comparison. <IMAGE>

Title: Imaging devices systems and methods
Inventor: ORAVA RISTO OLAVI
IPC: H04N5/335
Filed: 1995-04-24
Abstract: An imaging device 16 comprises a semiconductor substrate including an array of pixel cells 18. Each pixel cell is associated with an individually addressable pixel circuit for accumulating charge resulting from radiation 14, e.g. X-rays incident on a pixel detector. The pixel circuit and the pixel detector can either be implemented on a single substrate, or on two substrates bonded together. An imaging plane can be made up of one imaging device or a plurality of imaging devices tiled to form a mosaic. The imaging devices may be configured as a slot for certain applications, the slit or slot being scanned over the imaging plane. Control electronics 24 can include addressing logic for addressing individual pixel circuits for reading accumulated charge from the pixel circuits. Imaging optimisation can be achieved by determining maximum and minimum charge values for pixels for display, assigning extreme grey scale or colour values to the maximum and minimum charge values and allocating grey scale or colour values to an individual pixel according to a sliding scale between the extreme values. Scattered radiation can be detected and discarded by comparing the detected pixel value to a threshold value related to a minimum detected charge value expected for directly incident radiation and discarding detected pixel values less than said threshold value. <IMAGE>

Title: Stereo camera
Inventor: INABA MINORU
IPC: G03B35/10
Filed: 1996-10-02
Abstract: A stereo camera optimally corrects a parallax despite a photographing distance. Lens boards (8R,8L) of right and left photographing lenses (3R,3L) are mounted with slide guides (9R,9L) for obliquely feeding in an inter-optical axis distance approaching direction as the lens boards (8R,8L) are fed. When a focusing knob (14) is rotated, the photographing lenses (3R,3L) and a finder lens (2) are integrally advanced or retracted in response to the rotating direction of a cam shaft (11). The slide guides (9R,9L) are so disposed that the right and left visual fields are brought into agreement at a close distance during close distance photographing and the right and left visual fields are brought into agreement at a close distance as compared with the focal distance at the time of remote distance photographing. Accordingly, the unnatural feeling generated by the influence of a close distance subject under human collimation at the time of remote distance photographing is avoided, and an ideal stereo effect is obtained at all photographing distances.

IPC: G09G3/36
Filed: 1996-12-16
Abstract: A ferroelectric liquid crystal display comprises an addressable matrix of pixels and addressing circuitry for selectively addressing each pixel in order to vary the transmission level of the pixel relative to the transmission levels of the other pixels. The addressing circuitry includes spatial and/or temporal dither circuits for addressing separately addressable subpixels with different spatial dither signals and/or for addressing each pixel or subpixel with different temporal dither signals in separate subframes. In addition to such spatial and/or temporal dither, the addressing circuitry switches each pixel or subpixel between different grey states corresponding to different transmission levels, with at least two of the bits of spatial or temporal dither being switchable between more than two different grey states and at least one bit being switchable between a lesser number of different grey states than the or each other bit, so that a plurality of different overall transmission levels are achievable by different combinations of spatial and/or temporal dither and such grey states. This allows a larger number of substantially linearly spaced or suitably weighted grey levels to be produced than has previously been possible without giving rise to unacceptable complications.
