Abstract: This disclosure relates to an underground mining vehicle comprising a three-axis MEMS gyroscope rotatable about a rotation axis and a gyroscope interface that calculates a first rotation rate bias with respect to a first axis different to the rotation axis, a second rotation rate bias with respect to a second axis different to the first axis and different to the rotation axis, a rotation rate about the rotation axis based on the Earth rotation rate vector by correcting the rotational measurement data using the first rotation rate bias and the second rotation rate bias and a third rotation rate bias with respect to the rotation axis based on the calculated rotation rate about the rotation axis. A navigation unit receives the first rotation rate bias, the second rotation rate bias and the third rotation rate bias and calculates a pose of the vehicle.

Abstract: Viewers of a video stream may generate video clips including different portions of the video stream. Popularity measures may be computed for the video clips, for example based on tracked actions associated with the video clips, such as frequency of playing and sharing of the video clips. The popularity measures may be used to select and provide video clips to viewers. Video items may be generated by streamers, such as may include selected portions of video of streamers playing a game. A video item generated by a particular streamer may be displayed to viewers only during times when that particular streamer is participating in an active game session. Viewers of the video item may provide input that allows viewers to receive a live stream of the streamer's active game session that it is being played simultaneously with the display of the video item.

Abstract: 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.
