Abstract: A system may include an imaging system coupled to a host subsystem. The imaging system may include an image sensor that provides image frames to the host subsystem. The image sensor may include a data authentication subsystem that appends corresponding authentication data to each of the image frames. Each set of authentication data may be generated based on a subset of the image frame data (e.g., corresponding to image data generated by pixels defined by a sparse region-of-interest within the pixel array). The host subsystem may securely provide region-of-interest parameters to the image sensor to update the sparse region-of-interest in an adaptive manner to account for factors such as computational load of the host subsystem and authentication coverage for the entire pixel array.

Abstract: A depth camera assembly is used to obtain depth information describing a local area. The depth camera assembly includes a sensor having a plurality of pixels. Some or all of the pixels are divided into groups that are coupled to respective multi-purpose time-to-digital converters.

Abstract: A slider has a drum with alternating alpha and beta grooves, first stacked pulleys, and second stacked pulleys. First and second end pulleys are at opposite ends of the slider. A line wraps as a loop from the last beta groove, around the first end pulley, to the last alpha groove, back and forth around the first stacked pulleys, off the first alpha groove, around the second end pulley, to the first beta groove, back and forth around the second stacked pulleys, and back to the last beta groove. When the drum or the end pulleys are driven, the difference in circumferences of the grooves causes the slider to move toward one of the first or second end pulleys.

Abstract: Systems and methods for disposing of blackwater are disclosed. A first vessel contains a screw running through the vessel from a first end to a second end. The screw is surrounded radially by a filter. The first vessel has a blackwater inlet adjacent the first end. An extrusion plate is adjacent the second end of the first vessel.

A blackwater stream, consisting of a liquid component and the solids component, is passed through the blackwater inlet into the first vessel, is conveyed by the screw from the first end to the second end, and is pressurized against the extrusion plate. The liquid component is thereby forced from the blackwater stream through the filter and the solids component is forced through the extrusion plate into the combustor. The combustor is configured to combust the solids component.

Abstract: A depth measurement assembly (DMA) includes an illumination source that projects pulses of light (e.g., structured light) at a temporal pulsing frequency into a local area.

The controller determines a second estimated radial distance to the object based on an encoding of structured light and at least one of the captured images. The controller selects an estimated radial distance from the first set of radial distances.

Abstract: A device for moving an object is disclosed. The device has a drive cylinder with drive grooves and a set of idler pulleys. The idler pulleys are on a shaft that is parallel to the drive cylinder. Each of the idler pulleys rotate at an angle around the drive shaft that aligns the grooves of the idler pulleys to neighboring drive grooves. This allows the line to pass onto the drive groove, around an idler pulley, and onto a next adjacent drive groove. The line therefore winds back and forth between the drive grooves, the idler pulleys, and back to the next drive groove. One end of the line is placed under tension and the other is attached to an object or to a fixed member. The drive cylinder is driven and the line is moved through the device, or the device is moved along the line, respectively.

Abstract: A counterbalance system for an overhead door is disclosed. The system includes a torsion adjustment comprising a first portion and a second portion, the first and second portions being rotatable relative to one another in a first direction and not in a second direction opposite the first direction. The system also includes an anchor fixed to the first portion, a collar fixed to the second portion, the collar being selectively fixable to a shaft of the overhead door, and a spring coupled between the collar and the anchor. The spring supports at least a portion of the weight of the overhead door as the overhead door is raised and lowered. Rotating the first portion of the torsion calibration collar relative to the second portion of the torsion calibration collar increases torsion in the spring and therefore calibrates the spring to support a desired amount of the weight of the overhead door.
