A fan for providing thrust including at least one blade, a hub adapted to carry the at least one blade, a hub motor adapted to rotate the hub 360 degrees about a first axis extending perpendicular to the at least one blade, a first mount adapted to carry the hub, and a first mount motor adapted to rotate the hub 360 degrees about a second axis perpendicular to the first axis and extending through the first mount first and second side securing points. The first mount may include a first mount first side securing point adapted to pivotally carry the hub, and a first mount second side securing point adapted to pivotally carry the hub.

One or more switchable magnetic systems is located near a battery attachment surface of an electric vehicle, where the battery attachment surface is configured to accept and electronically connect to a battery pack. The electric vehicle also includes a control system that operates the one or more switchable magnetic system switching from a first to a second state. In the first state the magnetic field of the switchable magnetic system secures the battery pack to the battery attachment surface so that the battery pack is electronically coupled to an electric motor of the electric vehicle. When the control system receives a message corresponding to removal of the battery pack, the control system switches the switchable magnetic system to the second state such that the battery pack is removable from the battery attachment surface.

A sensor system includes a body, which includes an outer wall defining an inner opening centered about an axis, and radiating structures disposed in the opening and extending radially from the axis to the outer wall. The radiating structures are spaced circumferentially around the axis by a substantially equal angle. The system includes sensors that generate signals in response to deformations of the radiating structures. The signals provide vectors corresponding to the deformations. The deformations are caused by: (i) a torque about the axis, and (ii) a secondary torque or force. The system includes a controller electrically coupled to the sensors and configured to determine, by combining the vectors provided by the signals, a measurement of the torque about the axis. The sensors are arranged on the radiating structures such that combining the vectors substantially eliminates any effect of the secondary torque or force from the measurement.

A magnetic end effector utilizing a switchable Halbach array includes a pair of opposing members that can move towards and away from each other. The switchable Halbach arrays are located on or near the inner surface of the opposing members. A mechanical switching system is used to control the switchable Halbach arrays by moving one or more magnets that make up the switchable Halbach arrays. When manipulated in a certain way, the switchable Halbach arrays cause the opposing members to move towards each other, and when manipulate in a different manner, cause the opposing members to move away from each other.

A luminaire comprising a heat sink, a light source and a light guide. The light source is carried by the heat sink and configured to emit a source light. The light source includes a heat spreader having an inner surface and an outer surface, and a plurality of light-emitting diodes (LEDs) carried by a circuit board and disposed generally along an outer peripheral perimeter portion of the inner surface of the heat spreader, and positioned in thermal communication with the heat spreader. The light guide includes a lens with a plurality of optical elements disposed within the lens.

Example implementations may relate to a rotary transformer configured to transmit data. In some implementations, the rotary transformer may include a primary transformer component with a primary winding magnetically coupled to a secondary transformer component with a secondary winding. The rotary transformer may also include a resonant circuit including a frequency determining element and an amplifier. The frequency determining element may consist of the primary and secondary windings connected in parallel to respective capacitors. The primary transformer component may be coupled to a fixed-frequency signal generator. The rotary transformer may include a modulator coupled to the secondary transformer component and configured to vary the phase of the resonant circuit to generate an output signal and a demodulator coupled to the primary transformer component and configured to demodulate the output signal.

A luminaire including a housing and a light source carried by the housing. The housing may include a first and second set of light emitting elements and a lens assembly. The lens assembly may include a lens with a first refraction section having a surface smoothness within a first range, and a second refraction section having a surface smoothness within a second range. The lens assembly may include conical frustum light source receiving members located between the light source and the lens. The first and second set of light emitting elements is configured to emit light at a first and second beam angle. The light emitted by the first set and second set of light emitting elements form a combined light with a center beam and gradient wherein the center beam has a greater candle power than the gradient.

Tunable lighting apparatus

A device to detect occupancy of an environment includes a sensor to capture video frames from a location in the environment. The device may compare rules with data using a rules engine. The microcontroller may include a processor and memory to produce results indicative of a condition of the environment. The device may also include an interface through which the data is accessible. The device may generate results respective to the location in the environment. The microcontroller may be in communication with a network. The video frames may be concatenated to create an overview to display the video frames substantially seamlessly respective to the location in which the sensor is positioned. The overview may be viewable using the interface and the results of the analysis performed by the rules engine may be accessible using the interface.

A luminaire comprising a heat sink, a light source to emit a source light, a heat spreader having inner and outer surfaces, and LEDs carried by a circuit board and disposed generally along a periphery of the inner surface and positioned in thermal communication therewith. The luminaire comprises a reflector disposed coextensively with the LEDs and comprising an aperture. An outer edge of the aperture defines an inner rim of the reflector. A light guide positioned between the reflector and the light source exhibits a height defined as the distance between the inner surface of the heat spreader and a plane defined by the inner rim of the reflector. The light guide comprises deformations and/or lens portions configured to change the source light into a shaped light that is directed through the aperture. The deformations are characterized by a common shape positioned about a center of the light guide.

Each longitudinal section may comprise a first inclined section, a second inclined section, and a plurality of light-emitting diodes (LEDs). The first inclined section may be positioned in the direction of the base relative to the second inclined section.
