Title: Mattress protection
Inventor: BAIN DUNCAN
IPC: A61F5/48
Filed: 2003-11-21
Granted: 2005-11-23
Abstract: The present invention seeks to address the chronic and worsening problem of mattress management in hospitals by providing a mattress protector to shield a mattress or mattress core from body fluids, the protector not only comprising a shielding cover for the mattress or mattress core but also a detector in an inter- or under-layer of the cover to detect body fluid that has passed into or through the cover. The detector may be chemical, with the cover being a transparent cover and the under-layer being absorbent and having a dye that is activated by a body fluid to provide a visual indication of presence of the body fluid. In an alternative embodiment the detector may be an apparatus monitoring electrical conductivity. This suitably uses threads of electrically conductive yarn forming either the warp or weft of a thin flexible under layer of the protective cover and which are linked to a small processor which monitors the electrical conductivity between neighbouring conductive threads in the sensing layer.

Title: Microfluidic device
Inventor: ALLEN BRIAN PHILIP
IPC: B01L3/00
Filed: 2004-05-10
Granted: 2008-06-11
Abstract: A valve for controlling fluid flow in a microfluidic device is provided. The valve comprises a chamber ( 26 ) formed on a substrate ( 24 ), a heating coil ( 42 ), and a valve material ( 30 ) contained in the chamber ( 26 ). When the valve is to be closed, the heating coil is activated causing the valve material to expand out of the chamber, through a neck portion ( 28 ), and into the main channel ( 22 ), blocking it. Preferably, the valve material is paraffin wax, and is caused to melt by the heating coil ( 42 ). On melting the melted paraffin wax flows into the main channel whereupon it cools and solidifies. A restriction ( 34 ), with collar ( 36 ) provides a cool surface on which the solidifying wax accumulates.

Title: Method for driving liquid crystal display elements
IPC: G09G3/18
Filed: 1980-04-11
Granted: 1983-01-26
Abstract: A method for driving a liquid crystal display element so as to give a simultaneous analogue display of 3 kinds of information. The liquid crystal display element is driven over 1/3-duty periods by applying 4 kinds of voltage waveforms to one electrode formed on one of paired substrates, and at least 5 kinds of voltage waveforms to the other electrode on the other substrate, said electrodes being divided into a multiplicity of electrode patterns. In particular, one of the 4 kinds of voltage waveforms applied to the electrodes of one of said substrates is set to provide an OFF condition for the display regardless of which of the at least 5 voltage waveforms is applied to the electrodes of said other substrate. In this driving method only one chip of the element driving LSI is sufficient for a simultaneous analogue display of 3 kinds of information e.g. hour, minute, and second.

Title: Anti-neoplastic pharmaceutical compsn.
Inventor: FINOTTO MARTINO
IPC: A61K/
Filed: 1988-03-30
Granted: 1990-04-12
Abstract: In a telecine chain, the scanning raster is rotated by applying a magnetic field perpendicular to the axis of the electron beam, and the distortion introduced by such rotation is compensated for. A rotate coil is located about the scanning tube the coil formed so that current passing through it induces the magnetic field and thus effects the rotation of the raster. The degree of rotation is within limits dependent on the current, and the direction of rotation is dependent on the direction of current flow. There is pref. an Absolute Angle Generator which has an input common with the input which controls the current through the Rotate Coil and which provides outputs for the compensation functions. Focus compensation is effected by applying a stimulus to the focus system which is based on the degree of rotation being effected.
