Abstract: Optical time-of-flight detector arrays are costly and therefore enhancing their utilization (e.g. angular coverage range) is desirable. In one embodiment, a vehicle-based distributed LIDAR is disclosed, comprising a plurality of coherent fiber optic image bundles that transfer laser reflections from fields of view (FOVs) around the vehicle to a shared remotely located detector array. An optical multiplexor timeshares the FOVs from the coherent fiber bundles onto the remote detector array. Individual fibers in the coherent bundles gather laser reflections from distinct portions of a FOV, thereby enabling correlation of the original reflection directions with fiber locations within a bundle. Unlike an externally mounted LIDAR with direct access to a single FOV, or a LIDAR using a single optic fiber that loses direction data associated with laser reflections, the coherent fiber optic image bundles transfer both the timing and direction of laser reflections from multiple FOVs to a shared remote detector array.

Abstract: A LIDAR can utilize remote mirrors discovered in the local environment to gather reflections from remote locations. In one embodiment, a laser range finder identifies and tracks a remote mirror with variable placement in a field of view (e.g. a roadside mirror at an traffic intersection) and generates a dense non-uniform subset of outgoing laser pulses designed to cover the mirror portion of the field of view, thereby interrogating or data mining the indirect field of view offered by the remote mirror. In several embodiments a light detection and ranging (LIDAR) system, learns the position of a remotely located mirror, then identifies a subset of the laser reflections that have undergone deflection by that remote mirror and performs a correction step in the process of calculating 3D locations for the deflected subset of laser reflections.

Abstract: In one embodiment a laser range finder generates high-intensity laser pulses with intensities above a threshold intensity (e.g. above an eye-safe intensity) in an adaptive-intensity region of the field of view. The laser range finder further generates lower intensity (e.g. eye-safe) laser pulses in a protective guard region (e.g. a guard ring) that surrounds the high-intensity laser pulses. The guard region is located in the FOV such that ingress paths to the adaptive-intensity region must first traverse the lower-intensity guard region. The laser range finder analyzes laser reflections from the guard region to improve timely prediction of object intrusion into the adaptive-intensity region, thereby providing time to determine object trajectory or object classification. Upon determination that an object is likely to intersect the high-intensity laser pulses the laser range finder can discontinue the high-intensity laser pulses and instead generate laser pulses below the threshold intensity (e.g.

Abstract: In one embodiment a LIDAR uses data indicating the directions of outgoing laser beams to dynamically position an aperture relative to a laser detector and thereby track reflections from laser beams with the aperture. A spatial light modulator (SLM) can create an electronically controlled aperture relative to the field of view of a laser receiver. The SLM can electronically control the transparency of a plurality of segments to block light from unintended sources such as the sun or other vehicles, using knowledge of expected directions of laser reflections. Within embodiments a LIDAR can use a set of laser steering parameters to transmit a laser beam in various directions. The LIDAR can also use some of the steering parameters (e.g. indicating reflection directions) to configure an electronically steerable aperture to dynamically limit the portion of a laser detector that can receive light based on the anticipated directions of corresponding laser reflections.

Abstract: LIDAR measurements can be sparse in comparison to camera measurements. Hence, dynamically steering a LIDAR to regions of a field of view with more information (e.g. the detailed boundaries of objects) is beneficial. In one embodiment, a LIDAR system performs a non-uniform laser scan of a field of view based on sensor data. Data from an on-going or previous scan can be used to define dense scan regions within the field of view. The shape of dense scan regions can be iteratively improved (e.g. narrowed) based on localization of time-of-flight boundaries. Dense scan regions can be expressed in term of a set of laser steering parameters operable to dynamically steer a LIDAR. Within embodiments complex-shaped dense scan patterns can be selected or adapted based on an object classification (e.g. person or vehicle) or LIDAR location (e.g. an urban environment).

The circuit board can be a substrate for the one or more indirect input sensors. The circuit board can further comprise a second plurality of openings, at least some of which align with at least some of the openings in the grille, thereby providing sound transmission through the circuit board, while providing improved access for the sensors to the local environment in the vicinity of the smart speaker. Several embodiments enable the region behind the speaker grille to accomplish the dual functions sensing the local environment and sound transmission.

Abstract: This disclosure concerns estimating the number of people within building-based device networks. Increasingly, local area network (LAN) devices are capable of sensing people (e.g. smart appliances). Features of building layout, and physical arrangement of devices provide that only a subset of sensor data patterns can be accounted for by a single user (e.g. simultaneous activation of a smart TV and a motion sensor). Over time, a central controller (e.g. LAN gateway) can gather these building-specific sensor patterns and learn single occupant characteristics for a network (e.g. features or boundaries of single occupant capability). In one embodiment, the central controller generates a single occupancy criterion (e.g. a building-specific test), comprising single occupant characteristics, operable to test a subset of sensor data for single occupancy.

Abstract: Disclosed wherein is an electrical faceplate, such as a cover for a wall outlet or light switch, that uniformly illuminates by receiving light into a transparent lightguide, homogenizing the light within the lightguide and scattering the homogenized light preferentially through a front surface. In one embodiment a faceplate comprises a substrate operable to cover an interface between an electrical junction box and a wall. The faceplate further comprises a light receiving surface operable to receive light from a light generation component (e.g. an LED) and transmit the light substantially parallel to a front surface, thereby promoting reflection at the front surface that homogenizes the light intensity within the faceplate and a portion operable to scatter light through the front surface. Several embodiments provide a faceplate with a lightguide to homogenize light through a process of total internal reflection to provide uniform illumination of the faceplate.

Abstract: A central controller for device automation can control output devices (e.g. automated lights and speakers) based on calculating the indoor location of a person. In familiar surroundings (e.g. homes), people may leave their favorite wireless devices unattended (e.g. smartphones and tablet PCs) and in general people exhibit varying proximity to their mobile wireless devices. Hence, the indoor locations of mobile wireless devices are of variable importance when calculating indoor occupant locations. (e.g. exhibiting highly-correlated locations when handheld). In one embodiment, the central controller aggregates wireless signals from mobile wireless devices. The central controller calculates one or more mobile device location estimates and person-to-device proximities from the wireless signals.

Abstract: Internet connected electrical switches can benefit from an electronic rather than mechanical means to indicate their output power level. In one embodiment a touch-controlled dimmer switch is disclosed, including an interactive, uniformly illuminated bar of light, indicating the output power state of a dimmer switch. In response to a user moving their finger on a touch-sensitive front cover the dimmer switch illuminates corresponding regions with well-defined edges on a touch sensitive cover. The illuminated regions can be elongated, wider than a typical finger and encompass the most recently touched location, thereby providing improved feedback between the finger position on a touch sensitive surface and the operating point of an electrical switch.
