Title: High resolution camera sensor having a linear pixel array
Inventor: TURCHECK STANLEY P
IPC: G06K9/46
Filed: 1991-09-16
Abstract: The sensor includes a number of sensing elements (e.g. CCD 34) arranged to view a linear array of pixels transverse to the direction of travel of objects to be sensed. Each element is sampled in turn to produce a serial analog output signal, which is supplied to an A/D converter 48. A clocking circuit 35 is synchronised with scanning of the pixel array and transitions in the A/D converter output representative of sensed object edge points are used to gate count values from the clocking circuit for output e.g. to a buffer memory 52 and microprocessor 54. Analog signals from pixels where an object is present may be supplied via a circuit 40 to the A/D converter for sefting the threshold of the analog signal at which a transition in the digital signal occurs. The sensing elements may be CCD's whose conditioning voltage is applied in synchronism with resetting of the clocking circuit and whose outputs are sampled in succession between conditioning voltage applications so as to transfer each pixel charge fully and so as not to allow any charge to accumulate between CCD resets and the next scan. <IMAGE>

Patent GB-2282963-A (GB)
Title: Alternating pressure pad
Inventor: SCHILD ROLF
IPC: A61G7/057
Filed: 1993-10-19
Abstract: An alternating pressure pad or mattress for use in supporting a patient to prevent decubitus ulcers has two sets of alternately inflatable cells. The alternately inflatable cells overlie additional base cells in a lower layer of the mattress. These base cells are all simultaneously inflated whilst each of the sets of upper cells are repeatedly inflated and deflated in alternation over an inflation and deflation cycle. During a cycle each set of upper cells is deflated at least once while the patient is primarily supported by the other inflated set of cells. During each inflation and deflation cycle, the additional base cells are reduced in pressure at least once. In this way, even if a part of the patient is temporarily supported only on the lower base cells, the support pressure is temporarily reduced each cycle to minimise pressure effects on the patient.
