Abstract: The various implementations described herein include a video camera assembly that includes: (1) a housing; (2) an image sensor positioned within the housing and having a field of view corresponding to a scene in the smart home environment; and (3) a concave-shaped front face positioned in front of the image sensor such that light from the scene passes through the front face prior to entering the image sensor; where the front face includes: (a) an inner section corresponding to the image sensor; and (b) an outer section between the housing and the inner section, the outer section having a concave shape that extends from an outer periphery of the outer section to an inner periphery of the outer section; and where the concave shape extends around an entirety of the outer periphery.

Abstract: Font recommendation techniques are described that provide recommendations of fonts based on a variety of factors, automatically and without user intervention in real time. This is performable in a variety of ways by addressing a wide range of considerations as part of machine learning, examples of which include context, popularity, similarity, customization, and topic compatibility.

Abstract: A technique provides for wireless control of a machine tool, e.g. a portable machine tool used on-site. According to an embodiment, a motor is connected with a tool post assembly via a gearbox. The motor is coupled with a machine controller, and the tool post assembly is mounted proximate an object to be machined. For example, the object may be machined via a cutting tool mounted to a cutter post of the tool post assembly. The machine controller operates to control movement of the cutter post along a desired axis during the cutting operation. The machine controller and thus the cutting operation, however, are controlled wirelessly according to control instructions provided via a control device, e.g. a handheld control device, which is placed in wireless communication with the machine controller.

Abstract: A technique which facilitates cleaning of an interior of a pipe via access through a lateral hole in the pipe. The technique utilizes a control bar head coupled with a sweeper system which may be inserted into the pipe through the lateral hole. The sweeper system may comprise a plurality of shiftable sweeper heads which generally align for insertion through the lateral hole and then transition along the interior of the pipe to effectively sweep particles along the interior of the pipe. The sweeper system effectively clears an area of the interior of the pipe to facilitate a more effective seal with a subsequently inserted pipe isolation device.

Abstract: A bolt cutting apparatus including a cutter assembly and a carriage assembly attached to the cutter assembly. The carriage assembly includes a carriage housing, a tool post coupled to the carriage housing, a motor attached to the tool post, and a drive assembly configured to linearly move the tool post. The carriage assembly is configured to be secured to a structure, e.g. a flange. A cutter is attached to the motor and is disposed in the carriage housing. The motor is configured to rotate the cutter to cut a bolt on the structure, e.g. flange.

Abstract: A virtual reflective 3D volumetric display device and a method for creating virtual reflective 3D volumetric imagery are disclosed to present virtual 3D volumetric object imagery without head tracking or tracking a person's view or eye positions, and which neither presents refractive images nor requires VR goggles or headsets, but instead presents pure volumetric object imagery appearing in the three-dimensional shapes of objects, which can be simultaneously viewed by multiple viewers who each view the shapes of the virtual 3D volumetric object imagery from their own point of view. The three-dimension volumetric reflection display adapter and standalone screen delivers the appearance of volumetric effect with ease.

Abstract: This disclosure discloses a balance vehicle, comprising: a wheel, a support frame, a frame, a shock suspension component, foot pegs, a control rod and a handle grip; the support frame is fixed to an axle of the wheel; the frame is connected with the support frame in a slide way through a sliding block fixed to the support frame; the shock suspension component is disposed between the frame and the support frame, and configured to buffer the relative movement between the frame and the support frame; the foot pegs are fixed on the frame; the control rod can move forward and backward in the driving direction, and is configured that: when a driver pushes the control rod forward in the driving direction, the balance vehicle is accelerated; when the drive pulls the control rod backward in the driving direction, the balance vehicle is decelerated or draws back.
