Title: Improvements in or relating to continuous inkjet printers
Inventor: STUART MARK WALKINGTON
IPC: B41J2/185
Filed: 2016-05-13
Abstract: A method of controlling the flow of ink and/or air through the gutter line of a single jet continuous inkjet printer using a vacuum pump comprises controlling the vacuum pump so as to minimise the air flow through the gutter line while still maintaining enough suction through the gutter line to clear the line of ink. Minimising the air flow through the gutter line has the advantage of minimising the amount of solvent lost from the ink. The vacuum pump and therefore the ink/air flow may be controlled by monitoring fluctuations in pressure in the gutter line or by monitoring fluctuations in electrical current driving the vacuum pump. Also discloses are methods of determining a blockage in the gutter line, determining a mis-alignment between a jet of ink droplets and a gutter, conducting a shut-down routine and monitoring the performance of a gutter pump forming part of a continuous inkjet printer.

Title: Indoor radio map verification
Inventor: PAVEL INVANOV
IPC: G01S5/02
Filed: 2016-06-24
Abstract: A system that obtains position related information associated with a radio node from a global radio map stored within a first database; checking the validity of said radio node in an indoor radio map stored within a second database. Validating the radio node may comprise determining if the radio node has moved or is moving. The position of the radio emitter within the indoor radio map may be determined without the use of a Global Navigation Satellite System (GNSS); the position may instead be determined from indoor manual data collection. The radio transmitter may be declared invalid if the movement distance is above a threshold. Determination that the radio transmitter is moving may be made based on a number of samples. If the radio node is determined as invalid it may be removed from the indoor radio map or marked as invalid within the indoor radio map. The position related information within the first database may be based on location information from a GNSS.

Title: Cushion
Inventor: GAVIN JAMES
IPC: G08B21/04
Filed: 2017-01-10
Abstract: Pressure-detecting cushion 10 has pressure sensors, e.g. conductive sheets 18, 20, 24 separated by resilient insulating layers 22, 26 having through apertures 28, 30. When applied pressure exceeds a threshold over a pre-determined period of time, possibly zero, a verbal warning from speaker 38 issues instruction to move position, reducing risk of bedsores. The insulating layers may be of Combustion Modified High Resistance (CHMR) foam and might be 5mm or 10mm thick, calibrated according to the weight of the user. When a threshold is reached the conductive sheets, possibly carbon-printed polythene or conductive fibre mesh, may contact through the apertures. A possible second threshold may be used to account for a patient being able to sustain a higher pressure for a shorter period of time before the risk occurs. The cushion may also be inflatable, possibly with multiple chambers, with a gas pressure sensor as the detection means.
