Title: Method and device for adaptively enhancing an output of a detector
Inventor: PETRU RADU
IPC: G06T1/20
Filed: 2017-12-05
Abstract: Adaptively enhancing a detector output (being a numerical value in the interval between zero and one), comprising: binarising (ie. converting to 1 or 0) the output of the detector by comparing it with a threshold; storing a queue of bits, that is divided into segments, into which the binarised output is inserted; analysing each segment of the queue to provide intermediary outputs; fusing the intermediary outputs to provide a final output. Segment analysis and output combining may be performed by trainable classifiers. Merging outputs may involve averaging. Alpha filtering by computing a weighted average may be used to avoid abrupt transitions of detector output. Threshold may be a positive class threshold and may be set to obtain optimum trade-off between false positive rate and accuracy for a frame. Intermediate outputs may be based on comparison of percentage of binary zeros with false positive rate for a frame. Missed detections, and events not flagged, by computer vision detection algorithms may be reduced, so improving performance of advanced driving assistance systems.

Title: Methods and apparatus for manufacturing a microfluidic arrangement , and a microfluidic arrangement
Inventor: EDMOND WALSH
IPC: B01L3/00
Filed: 2017-12-13
Abstract: A method of manufacturing a microfluidic arrangement comprises modifying a selected region of a substrate surface 14 by moving a probe over the selected region while maintaining contact between the probe and the substrate surface to create a modified region 60. Modification causes an equilibrium contact angle of a first liquid 11, when disposed at the selected region, to be to be higher after modification than before. The modified region forms one or more unmodified isolated regions 64 on the substrate surface by surrounding each isolated region with a closed path of modification. Ideally, a hydrophilic substrate 10 has selected region modification to create hydrophobic or less hydrophilic regions which surround isolated hydrophilic regions or pockets. The method further comprises forming a microfluidic arrangement comprising a first liquid body 6, 11 in direct contact with each isolated region, and a second liquid 12 in direct contact with, and covering, each first liquid body and the modified region, wherein the second liquid is immiscible with the first liquid, and each first liquid body is held in shape predominantly by surface tension and substantially fills each isolated region. An apparatus for manufacturing the arrangement comprises a substrate, scanning device, probe, dispensing system and controller.

Abstract: An image data encoding apparatus comprises: an entropy encoder to selectively encode data items representing image data so as to generate encoded binarized symbols of successive output data units; the entropy encoder generates an output data stream subject to a constraint defining an upper limit to the number of binarized symbols that may be expressed by any individual output data unit relative to the size in bytes of that output data unit, in which the entropy encoder provides padding data, for each output data unit which does not meet the constraint, so as to increase the size in bytes of that output data unit in order to meet the constraint. The apparatus comprises: an attribute detector to detect an encoding attribute applicable to a given output data unit; and a selector to select, in response to the detected encoding attribute, a constraint, for use with the given output data unit, from two or more candidate constraints. A first, context adaptive binary arithmetic coding (CABAC) or a second, bypass, encoding system may be used.
