Filed:

Dec 11, 2019

Appl. No.:

16/710752

Inventors:

- Baden, CH
John Awald - Redmond WA, US
Kevin Curtis - Redmond WA, US
Reynaldo Bernal - Redmond WA, US

International Classification:

G05B 15/02
H02J 3/00

Abstract:

Outages and/or switching operations associated with an electrical energy distribution system (e.g., a power grid system) are managed. In an implementation, a system provides for receiving outage request information related to a request to interrupt a power supply provided to a device in an electrical energy distribution system, determining switching information related to a set of steps to de-energize a portion of the electrical energy distribution system associated with the device based on the outage request information, and performing a switching operation to de-energize the portion of the electrical energy distribution system based on the switching information.

G02B 5/30
F21V 8/00
G02F 1/137

Abstract:

An optical device comprising may include a light turning element. The optical device can include a first surface that is parallel to a horizontal axis and a second surface opposite to the first surface. The optical device may include a light module that includes a plurality of light emitters. The light module can be configured to combine light for the plurality of emitters. The optical device can further include a light input surface that is between the first and the second surfaces and is disposed with respect to the light module to receive light emitted from the plurality of emitters. The optical device may include an end reflector that is disposed on a side opposite the light input surface. The light coupled into the light turning element may be reflected by the end reflector and/or reflected from the second surface towards the first surface.

Abstract:

An optical device comprising may include a wedge-shaped light turning element. The optical device can include a first surface that is parallel to a horizontal axis and a second surface opposite to the first surface that is inclined with respect to the horizontal axis by a wedge angle. The optical device may include a light module that includes a plurality of light emitters. The light module can be configured to combine light for the plurality of emitters. The optical device can further include a light input surface that is between the first and the second surfaces and is disposed with respect to the light module to receive light emitted from the plurality of emitters. The optical device may include an end reflector that is disposed on a side opposite the light input surface. The second surface may be inclined such that a height of the light input surface is less than a height of the side opposite the light input surface. The light coupled into the wedge-shaped light turning element may be reflected by the end reflector and/or reflected from the second surface towards the first surface.

International Classification:

G02B 27/01
F21V 8/00

Abstract:

A method and system for increasing dynamic digitized wavefront resolution, i.e., the density of output beamlets, can include receiving a single collimated source light beam and producing multiple output beamlets spatially offset when out-coupled from a waveguide. The multiple output beamlets can be obtained by offsetting and replicating a collimated source light beam. Alternatively, the multiple output beamlets can be obtained by using a collimated incoming source light beam having multiple input beams with different wavelengths in the vicinity of the nominal wavelength of a particular color. The collimated incoming source light beam can be in-coupled into the eyepiece designed for the nominal wavelength. The input beams with multiple wavelengths take different paths when they undergo total internal reflection in the waveguide, which produces multiple output beamlets.
