Title: Electronic image resolution enhancement by frequency-domain extrapolation
Inventor: LEE CHUEN-CHIEN
IPC: G06T3/40
Filed: 1995-05-02
Abstract: The resolution of an original image, represented as a pixel array (49, 66), is increased by applying a spectral transformation to the pixel array, producing a spectral array (52, 66) representing the image, and then applying an inverting spectral transformation to produce a larger pixel array (56, 70).  The inverting spectral transformation is of a kind designed to convert high frequency spectral components not present in the original image or identified by the spectral array.          These high-frequency terms of the inverting spectral transformation are either ignored or supplied with zero values.  As a result, the final, larger pixel array has the same spectral distribution as the original pixel array, but a larger number of pixels.

Title: Refrigeration system
Inventor: MILLER JEREMY PAUL
IPC: F25B9/00
Filed: 1995-05-11
Abstract: A refrigeration system using air as the refrigerant comprises a compressor which compresses air to 84 bar g. The compressed air is cooled first by cooling water and then by returning air in a plate-fin heat exchanger before being expanded to 59 bar g in an expander. The expanded air at -61°C is passed through indirect cooling coils in a cold store which it leaves at -45°C. This air is then passed through the plate-fin heat exchanger before being recycled to the compressor. The refrigera-tion delivered is about 1.05kw refrigeration/kw power input.

A mechanism for driving the actuator is also taught which comprises a housing and an overcentre assembly of two interlocking parts which are driven between the overcentre and collapsed position by use of aunattached sled which moves axially within the housing and is driven by a pair of buttons extending from the housing. A terminal device locking mechanism is taught for releasable locking a terminal device to a prosthetic limb. The locking device includes a biased retaining means which allows passage of a stem of the terminal device into the bore of a prosthetic limb but which engages the stem once it has been fully inserted. The stem is released from the bore by driving the biasing means out ofengagement with the stem.

Abstract: In the image pickup phase (A), right and left images are taken in through two image-pickup devices (S101, S102). Then, in the next feature extraction phase (B), right and left images are respectively subjected  to  feature  extraction  (S103,  S104).          Thereafter, in the succeeding matching phase (C), the extracted features of right and left images are compared to check how they match with each other (step S105).  More specifically, in the matching phase (C), a one-dimensional window is set, this one-dimensional window is shifted along the left image in accordance with a predetermined scanning rule so as to successively set overlapped one-dimensional windows, and a matching operation is performed by comparing the image features within one window and corresponding image features on the right image. Subsequently, in the disparity determination phase (D),  the left image is dissected  or  divided  into  plural  blocks  each  having  a predetermined size, a histogram in each block is created from disparities obtained by the matching operation based on one-dimensional windows involving pixels of a concerned block, and a specific disparity just corresponding to the peak of thus obtained  histogram  is  identified  as  a  valid  disparity representing the concerned block (S106).
