Abstract: A grinder is provided that grinds materials such as tobacco, herb, spices, or food into smaller pieces for subsequent use. In some embodiments, relative motion between two components grinds the material into smaller pieces. In some embodiments, a cord is used to induce rotational motion between components. In various embodiments, a gear system having a driver is used to induce rotational motion where the driver is moved against a surface to drive the gear system. In some embodiments, a user moves a collar, a handle, or other component to induce rotational motion or longitudinal motion to grind the material.

Abstract: A light projection system including a light source and a light controller to generate modulatable beams of light and an angular light modulator (ALM) positioned to selectively direct the light from each beam. The light controller can be a spatial light modulator or a processor programmed to control light output. The angular light modulator may be a digital micromirror device (DMD). The ALM may be configured to direct the images into diffraction orders or using scanning the images. A LIDAR system to detect a position of an object including a first source of a two-dimensional array of beams of light and ALM to project light into a selected one of a plurality of directions. An illumination system, comprising a first angular-spatial light modulator (ASLM) and a second ASLM system configured such a first beam and a second beam of light intersect.

Abstract: A beam steering apparatus including a first actuatable micromirror array (AMA) having a pitch, p, adapted to impart a modulation to a wavefront incident on the first AMA by a transition between a first state and a second state, wherein the first AMA has a transition time (T) between the first state and the second state, and at least one light source adapted to provide the incident wavefront having a duration, t, to the first AMA, where t?T. The AMA may be a MEMS device such as a digital micromirror array. The beam steering apparatus may constitute a portion of LIDAR system.

Abstract: A light projection system including a light source, a light controller optically and/or electrically coupled to the light source to generate a plurality of spatially-separated and independently-modulatable beams of light, and an angular light modulator (ALM) positioned to receive the beams of light and selectively direct the light from each beam into one of a plurality of directions. The light source can include a laser diode array. The light controller can be a spatial light modulator or a processor programmed to control an output of each of the lasers of the laser diode array. The angular light modulator may be a digital micromirror device (DMD). The ALM may be configured to project the images into corresponding diffraction orders of the ALM or the ALM may be configured to continuously scan the images.
