Abstract: A stator for an electrical machine includes: an annular housing extending around a central axis (X-X); a first circumferential flow channel extending around the housing; a second circumferential flow channel axially spaced from the first circumferential flow channel and extending around the housing; and a plurality of windings. The plurality of windings are circumferentially spaced about the housing to form a passage between each two adjacent windings. Each passage is in fluid communication with both the first circumferential flow channel and the second circumferential flow channel. The first circumferential flow channel is closed to flow at a first circumferential location and the second circumferential flow channel is closed to flow at a second circumferential location, removed from the first circumferential location so as to form a first set of passages (S1) connected in parallel and a second, separate set of passages (S2) connected in parallel.

Abstract: A stator is described herein comprising a first longitudinally extending slot having a cavity defined by a first inwardly facing longitudinal surface and a second inwardly facing longitudinal surface; said stator further comprising a spacer provided in said cavity of said first slot, said spacer comprising a first spacer component that comprises a first sheet of material having a first sheet surface facing inwardly into said slot and an opposite sheet surface that is in contact with and extends along the first longitudinally extending inner surface of said slot and wherein said inwardly facing first sheet surface of said first spacer component comprises at least one ridge projection extending along its length L. Methods for assembling such stators are also described.

Abstract: A dental cleaning appliance includes a handle and a fluid delivery system for delivering a burst of working fluid to the teeth of a user. Part of the fluid delivery system is moveable relative to the handle as the appliance is moved along the teeth of the user. A sensor provides an output which varies with movement of that part of the fluid delivery system relative to the handle. A control circuit actuates the delivery of working fluid to the teeth of the user depending on the output from the sensor.

Abstract: A photovoltaic system having at least one solar cell and a secondary direct current power supply connected to the at least one solar cell. The secondary power supply is configured for constant voltage operation to input power to the photovoltaic cell to maintain operation of the solar cell at or near an optimum voltage working level for the solar cell.

Abstract: Embodiments of the present invention provide a control system for a hybrid solar power supply system, in particular for direct current (DC) power supply. The hybrid solar power supply control system includes a power arbiter and a power controller. The power arbiter unit is connectable to a photovoltaic power supply and one or more other power supplies and comprises circuitry to connect the input photovoltaic power supply and other power supplies and combine power from one or more power supplies for direct current (DC) output, and transition between power supplies based on the available input power from each power supply. The power controller is configured to vary the apparent load applied at the DC output to control the power drawn from the one or more power supplies.

Abstract: A system, such as a heat exchange assembly includes a support structure having a recess, a first support end, a second support end, and a support portion extending between the first and second support ends. The support structure further includes a plurality of projections protruding from a portion of a surface of the support structure, corresponding to the support portion. The support structure is a primary heat sink. The heat exchange assembly includes a vapor chamber having a casing and a wick disposed within the casing. The vapor chamber is disposed within the recess and coupled to a surface of the support structure such that the plurality of projections surrounds the vapor chamber.

Abstract: A camera unit and method of control are described. The camera unit has a camera flash sub-unit configurable to emit flash light having an adjustable characteristic. A camera sensor sub-unit generates raw color data when exposed to light for processing into a digital image. The camera unit also includes a camera controller for coordinating operation of the camera flash sub-unit and the camera sensor sub-unit. The camera controller monitors one or more ambient light characteristics in a vicinity of the camera unit. Prior to receiving a command instructing the camera unit to generate the digital image, the camera controller repeatedly configures the camera flash sub-unit based on the monitored ambient light characteristics to adjust the characteristics of the emitted flash light. Once the camera controller receives the command, the camera sensor sub-unit is instructed to expose an image sensor using the pre-adjusted camera flash light to increase illumination.

Abstract: The controlling of access to a file system entity based on location of the requestor and operation expiry data of the file system entity. Operation expiry data and location data are associated with a file system entity (e.g., a file, a directory, a partition, or a disk) such that the file system entity and the operation expiry data and the location data are moved or copied atomically together. Upon receiving a request to perform an operation on the file system entity, the system identifies a location status of the requestor. The system then identifies expiry data that corresponds to the location status, and that is associated with the requested operation. The system then uses the identified expiry data to determine whether or not the requested file operation is to be permitted.
