Title: Electricity supply apparatus and method
Inventor: MALCOLM DUNCAN MCCULLOCH
IPC: H02M7/5387
Filed: 2014-10-31
Abstract: An electricity supply apparatus has an input for receiving a direct current electricity supply, and has a converter (inverter) arranged to convert the electricity supply received by the input to generate, at an output, a voltage waveform of alternating polarity, which alternates in repeated cycles. A value A is given by the integral over a half cycle of the voltage waveform of the difference between: (i) the square of the instantaneous voltage; and (ii) the average value of the square of the voltage, the integral being taken only when the square of the instantaneous voltage exceeds the average value of the square of the voltage. A value B is given by the integral over a half cycle of the voltage waveform of the square of the instantaneous voltage. The ratio A:B is not greater than 0.2, where a lower ratio represents a lower requirement for energy storage within the inverter. The converter is also arranged to generate the voltage waveform such that it is in anti-phase with a substantially sinusoidally alternating electricity supply. The voltage waveform may be a substantially square wave. The sinusoidally alternating electricity supply may be from an electricity distribution grid.

Title: Improvements in dosimetry techniques for radiotherapy
Inventor: ABDUL SAYEED
IPC: A61N5/10
Filed: 2015-06-12
Abstract: The invention provides radiotherapy apparatus comprising a source or therapeutic radiation, a detector and a controller. The controller is adapted to receive dose delivery instructions and patient data including patient geometry, causes the apparatus to perform the delivery instructions and receives the output of the detector, and is adapted to combine this data with the patient data to calculate an first dose distribution; the controller then causes the apparatus to run further delivery instructions, receives a further output from the detector and calculates a second dose distribution which is then compared to the first. The apparatus may issue an alert if the difference between the first and second dose distributions exceeds a predetermined threshold value, or may cause treatment to cease. The first dose distribution may be carried out on a different day to the second. The analysis may involve back-projection of stored radiation fluence. The patient data may be derived from a CT or MRI scan. The detector may be a portal imager or EPID.

Title: Transmitter for transmitting a digital transmission signal in a partial broadcast area of a broadcast area of a single-frequency network
Inventor: STEFAN TEUSCHER
IPC: H04L27/26
Filed: 2015-11-10
Abstract: A transmitter for transmitting a digital transmission signal in a single-frequency network (100, Figure 1). The digital transmission signal contains at least one broadcast program and is broadcast as an OFDM (Orthogonal Frequency Division Multiplexing)-signal. The digital transmission signal contains OFDM frames, each frame containing at least one program symbol and at least one empty symbol which prevents the reception of a broadcast program from an adjacent transmitter in the SFN. The transmitter is configured to generate an empty symbol in a manner which is equivalent to or identical to the following steps: a. generating a frequency spectrum (a) for a program symbol for the broadcast program from the adjacent transmitter, b. suppressing some carriers in the frequency spectrum of the program symbol, and c. including the program symbol with such a suppressed frequency spectrum as an empty symbol in the OFDM frame. Empty symbols of the type derived in this way my prevent interference between the blank symbol and the program symbol transmitted by the adjacent transmitter. The transmitter may be used in transmitting regional radio programs in a DAB network.

Title: A hybrid distributed storage system
Inventor: FREDERIK DE SCHRIJVER
IPC: G06F11/08
Filed: 2016-07-15
Abstract: A method of operating a distributed object storage system includes selecting a set of storage elements 34, e.g. hard drives, upon each of which are stored a number of level-1 encoding fragments 730 of an object to be stored 520. The number of storage elements is equal to the basic number of storage devices 812 which are necessary to reconstruct the data object, plus the desired number of redundant storage devices 822. A second set of storage elements 36 is selected, being fewer than the basic number of storage elements of the level-1 storage set, upon which a group of level-2 fragments 750 is stored. The stored object may be reconstructed from the level one or level two fragments, or a combination of both. By encoding the object twice, additional redundancy can be obtained. The encoding of the fragments may be based on an erasure code.

Title: WIC (Water Injection Coupling)
Inventor: JASON STEVEN MCKENNA
IPC: B24C7/00
Filed: 2017-03-27
Abstract: A water injection coupling used for vapour abrasive blasting comprises of an outer sleeve and injector body which are welded to form a one-piece coupling. A series of jets are formed within a water well ingress and allow the injection of fluid in the direction of air and abrasive flow to form a slurry. The coupling may include standard sized threads for coupling to a metering valve and to a shot blasting claw coupling. The coupling may be made from stainless steel and enables the conversion of a dry blast machine to a wet blast machine by fitting the coupling to an abrasive metering valve post grit flow. This enables the injection of water close to the abrasive valve replacing the need for a water injection blasting nozzle. The coupling is designed to keep the water injection jets out of the flow of air and abrasive to reduce or eliminate internal coupling wear. Water may be injected into the coupling at a pressure sufficient to overcome back pressure within a blasting hose.
