Title: A three dimensional printing apparatus, a material dispensing unit therefor and a method
Inventor: MAXIMILIAN BARCLAY BURT
IPC: B33Y40/00
Filed: 2016-07-01
Abstract: A material dispensing unit 1 for a three dimensional printing apparatus has a nozzle 3 for depositing particulate material 5 on a build surface 7, where the nozzle defines a through passage 9 for the material. The through passage has an inlet end 11 for receiving the material and 10 an outlet end 15 for dispensing the material. A valve 21 is provided for controlling flow of the material via the through passage, the valve being operable between open and closed positions. Flow of said material into the through passage is blocked when in the closed position and, when in the open position, flow of the material into the through passage is allowed. Preferably, the through passage has a width W sufficient to allow only a single particle of the particulate material to pass at a time to be deposited on the build surface such that a trail of particles deposited during relative movement of the dispensing unit across the build surface takes the form of a line of thickness one particle high. The valve may comprise an actuator 49, preferably a cam pair 53, 55, which moves a through channel 25 in the valve body 23 into and out of alignment with the through passage. A plurality of dispensing units may be arranged in an array and may be adapted to dispense different particulate materials. A three dimensional printing apparatus (200, fig 25) is further disclosed comprising one or more dispensing units (1a, 1b, fig 25) for dispensing particulate material, an enclosure (137, fig 25) for containing the material dispensed by the one or more dispensing units and one or more heating elements (210, 212, fig 25) for heating the material contained in the enclosure to a first predetermined temperature.

Title: User focus activated voice recognition
Inventor: Russell S VanBlon
IPC: G10L15/25
Filed: 2016-11-24
Abstract: Speech recognition on a device (eg. a phone) is triggered when an image of the user indicates that their focus is directed at the device (via eg. a head- or gaze-tracking camera) when a command is spoken, and powered down when their attention is directed elsewhere for a predetermined time. This may be used in conjunction with a trigger phrase or wake up word to increase detection confidence in eg. noisy conditions.

Title: Apparatus, system and method for validating images of a phantom
Inventor: XAVIER GOLAY
IPC: G01R33/58
Filed: 2017-01-12
Abstract: Data from one or more sensors measuring parameters associated with the operating state of a phantom during a scan 47 is input to a computer model 48, which is used to produce reference image data. This is compared with the acquired image 49 in order to return a pass/fail score, indicating acceptability of imaging system calibration. Synchronization 45 may occur before image acquisition. The measured parameters may be, for example, phantom fluid flow rate, pressure, pH or concentration of a dissolved compound such as glucose, or temperature and are used with Computational Flow Dynamics (CFD) to produce the ground truth model for comparison. A predetermined threshold level may be based on ISO standards. Adjustments may be made until a pass score is returned. The method may be used with scanners using e.g. MRI or PET techniques, and may be applicable to a diffusion or perfusion phantom.

Title: Calibration for amplifier with configurable final output stage
Inventor: LEI ZHU
IPC: H03F3/217
Filed: 2017-05-30
Abstract: An amplifier 16 has at least a first stage 22 generating an intermediate signal VINT and a final output stage 24 with selectable first and second paths. The first path, which may comprise a Class-D audio output stage 42, includes a modulator 122 and plurality of switches 124 for modulating the intermediate signal and generating an output signal VOUT when selected. The second stage, which may be a Class-AB audio output stage 44, generates the output signal when selected. In a calibration mode, a calibration subsystem 126 applies a common-mode voltage VCM through the second path and to the modulator input, and receives a calibration signal indicative of an offset between the first and second paths from the modulator output VMOD. One or more modulator parameters are modified to compensate for the offset. Additionally, or alternatively (Fig. 12), first and second test signals in anti-phase are input to the first and second paths respectively. A feedback network 26 coupled between the amplifier output and input allows for a calibration signal indicative of first and second path gain difference to be generated at the first stage output VINT. One or more parameters of the second path are modified to compensate for the gain difference.
Patent GB-2549019-A (GB)
Title: Fault current limiter
Inventor: JEREMY PETER HALL
IPC: H02H9/02
Filed: 2012-08-30
Abstract: Fault Current limiter having two ring cores and a series of permanent magnets 2 sandwiched between the cores, wherein there are air gaps 5 between the series of permanent magnets. The magnetic moments of neighbouring permanent magnets point in opposite directions and, in this way, there is a bifurcated magnetic field in the core location adjacent to each permanent magnet. An AC coil is wound around the cores. In this structure, the direction of an AC flux produced by the AC coil along the cores is orthogonal to the permanent magnets. Under normal operating conditions, the magnetic field provided by the permanent magnets saturates the cores while under fault conditions the saturation is overcome which increases the net relative permeability of the cores. This leads to an increase in the inductance of the AC coil which prevents or limits the passage of a fault current through the AC coil.
