QUALITY INDICATORS FOR COLLECTION OF AND AUTOMATED MEASUREMENT ON ULTRASOUND IMAGES
Aspects of the technology described herein relate to techniques for calculating, during imaging, a quality of a sequence of images collected during the imaging. Calculating the quality of the sequence of images may include calculating a probability that a medical professional would use a given image for clinical evaluation and a confidence that an automated analysis segmentation performed on the given image is correct. Techniques described herein also include receiving a trigger to perform an automatic measurement on a sequence of images, calculating a quality of the sequence of images, determining whether the quality of the sequence of images exceeds a threshold quality, and performing the automatic measurement on the sequence of images based on determining that the quality of the sequence of images exceeds the threshold quality.

Communication-less bistatic ranging
A transmitter for communication-less bistatic ranging includes a photon emitter configured to emit a plurality of photons at particular times in a pointing direction, and a processor configured to identify a particular sub-code of a plurality of sub-codes based on a dynamic state of the transmitter, each one of the plurality of sub-codes including a portion of a long optimal ranging code, generate a plurality of encoded pulse timings by dithering pulse timings from a nominal repetition frequency based on the particular sub-code, and control the photon emitter to emit the plurality of photons at the plurality of encoded pulse timings.
Machine guidance integration
Disclosed herein is a system for controlling a mining machine within an underground mine. A rotatable laser source sends laser light and return light sensor receives reflected laser light and provides an indication of distance and return light intensity at multiple different rotation angles. A co-ordinate reference point comprises a pattern of varying reflectivity and provides at least a 2D co-ordinate position. A processor determines an absolute co-ordinate position in space of the mining machine as the mining machine moves through the underground mine. The processor collects intensity values of reflected laser light for multiple respective rotation angles and detects the pattern of the reference point in the multiple intensity values of reflected laser light, and determines the absolute co-ordinate position in space of the mining machine based on spatial information of the detected pattern.

ENHANCED MANAGEMENT OF ELECTRICAL RESOURCES FOR ELECTRIC VEHICLES
Devices, systems, and methods for management of electrical resources for electric vehicles. A method may include receiving, by a vehicle, sensor data indicative of a first luminosity of a location, and determining that the first luminosity of the location exceeds a luminosity threshold. The method may include determining, based on the first luminosity exceeding the luminosity threshold, a second luminosity to apply to lights of the vehicle while the vehicle is at the location, the second luminosity greater than zero. The method may include applying the second luminosity to the lights while the vehicle is at the location.
Systems, methods and apparatus for characterizing stick-up height, position and orientation of a drill pipe
A processor is operably coupled to a time of flight (TOF) camera, a light detection and ranging (LIDAR) sensor, and an optical camera. The processor can receive a TOF signal representative of a first coordinate associated with a stick-up height of a tool joint of a pipe of a drill string during a tripping operation on a rig drill floor, and a pitch and a roll of the tool joint. The processor can receive a LIDAR signal representative of a second coordinate associated with the stick-up height, and the pitch of the tool joint. The processor can receive an optical camera signal representative of a third coordinate associated with the stick-up height of the tool joint and the roll of the tool joint. The processor can generate a pose estimate and an orientation estimate based on the signals.
Autonomous gating selection to reduce noise in direct time-of-flight depth sensing
A depth camera assembly (DCA) includes a direct time of flight system for determining depth information for a local area. The DCA includes an illumination source, a camera, and a controller. The illumination source projects light (e.g., pulse of light) into the local area. The camera detects reflections of the projected light from objects in the local area. Using an internal gating selection procedure, the controller selects a gate window that is likely to be associated with reflection of a pulse of light from an object. The selected gate may be used for depth determination. The internal gating selection procedures may be achieved through external target location and selection or through internal self-selection.
Motion detection device
A method includes emitting, by a single sensor of a device, a signal into a region; receiving, by the single sensor, a reflected signal; and detecting motion in a detection cone comprising a central axis based on the reflected signal, wherein detecting motion comprises detecting a first type of motion from a first position to a second position, and detecting a second type of motion from the second position to the first position.
LIDAR sensor for detecting an object
A LIDAR sensor for detecting an object in the surroundings and a method of the LIDAR sensor includes a light source emitting electromagnetic radiation, a micromechanical deflection mirror deflecting the emitted electromagnetic radiation by at least one angle into the surroundings, and a mirror, which includes an aperture situated on a main beam axis of the light source, deflecting onto an optical receiver received electromagnetic radiation that has been reflected from the object.
