A switchable rotation drive device has a switching mechanism wherein a first connecting sleeve that always rotates integrally with a motor hollow rotor, and a second connecting sleeve that always rotates integrally with a planetary carrier of a planetary gear reduction mechanism are connected via a bearing in a relatively rotatable state, and the first connecting sleeve is formed with a sun gear. By sliding the switching mechanism, the output shaft can be switched between high-speed rotation and low-speed rotation. In comparison to a case in which the entirety of the planetary gear reduction mechanism is made to slide, the sliding region may be smaller, and the required space needed to allow sliding may also be smaller. Therefore, it is advantageous to reduce the size of the device and make it more compact.

A lidar-based 3-D point cloud measuring system and method. An example system includes a base, a housing, a plurality of photon transmitters and photon detectors contained within the housing, a rotary motor that rotates the housing about the base, and a communication component that allows transmission of signals generated by the photon detectors to external components. The rotary component includes a rotary power coupling configured to provide power from an external source to the rotary motor, the photon transmitters, and the photon detectors. In another embodiment, the photon transmitters and detectors of each pair are held in a fixed relationship with each other. In yet another embodiment, a single detector is “shared” among several lasers by focusing several detection regions onto a single detector, or by using a single, large detector.

A vacuum cleaner comprises adjacent housings, which contain the filtration and suction fan motor assembly of the vacuum cleaner.

An apparatus having a member that revolves about a remote center of motion (RCM) and a base link coupled to a mounting fixture. A first and second link are pivotably coupled to the member at respective distances from the RCM and are translatable relative to the base link along a first direction, at a fixed ratio of displacement. The ratio of respective distances equals a fixed ratio of displacement. The apparatus has a translational motion generator for a first and second element along parallel opposing directions. The translational motion generator is disposed on the first link and enables motion parallel to the first direction. The base link is fixed in position, the first element is fixed to the base link and the second element is fixed to the second link, such that the first and second link may translate relative to the base link with fixed ratio of displacement.

A light guide with input and output faces 2, 3a is polar-symmetric about the first face 2 and has optical properties such that the angle at which a ray is injected into the first face determines the position at which it leaves the second face 3a, or, if operated in the reverse direction, the position at which the ray enters the second face determines the angle at which the ray leaves the second face. The light guide includes a tapered transparent sheet 3, light from the first face entering at the thick end of this sheet, and the second face forming one face of the tapered sheet. An input / output slab 4 adjoins the tapered sheet 3 for fan-out of light from the first face 2 to the tapered sheet, and a transition region 8 is located between flat and tapered sheets. The polar symmetry means that light rays always travel in line with the taper direction, which suppresses banding. Preferably the light guide further includes a prism device 20 for folding the light so that the flat and tapered sheets can be folded over each other. A method of making such a prism is also disclosed.

An electric balance vehicle including a top cover, a bottom cover, an inner cover, a rotating mechanism, two wheels, two hub motors, a plurality of sensors, a power supply, and a controller is described herein. The bottom cover is fixed to the top cover. The inner cover is fixed between the top cover and the bottom cover. The two wheels are rotatably fixed at two sides of the inner cover, respectively. The two hub motors are fixed in the two wheels, respectively. The plurality of sensors is disposed between the bottom cover and the inner cover, respectively. The power supply is fixed between the first bottom cover and the first inner cover. The controller is fixed between the second bottom cover and the second inner cover, the controller is electrically connected with the plurality of sensors, the power supply, and the hub motors.

Method and apparatus for locating and quantifying sound sources using an array of acoustic vector probes (200). Signals received at the probes are converted to digital form and fed into a digital signal processor (400) which computes the sound pressure and the sound-intensity vector at each probe. The set of sound-intensity vectors measured by the array provides a set of directions to a sound source (100) whose approximate spatial coordinates are determined using a least-squares triangulation formula. The sound-intensity vectors also determine sound-power flow from the source. In addition sound pressure measured by the probes can be phased to form a sensitivity beam (250) for scanning a source. Sound-intensity measurements made concurrently can be used to determine the spatial coordinates of the part being scanned and the sound power radiated by that part. Results are displayed on a computer screen or other device (500) permitting an operator to interact with and control the apparatus. Additional related features and methods are disclosed.

A point-of-care touch / click entry system can be used to replace and / or augment standard dictation transcription models in medical record systems (which comprise institution-centric data). Key word entry can better standardized medical record display, can be linked directly to diagnostic and billing codes to automate billing thus decreasing payers claims of fraud and can be used to insert data variables directly into relational databases to improve outcome analysis. In total the “clinical operating system (COS) and clinical information system (CIS) can quickly and accurately produce “longitudinal” lifetime medical records (which comprise patient-centric data). The longitudinal medical record can be used in accordance with medical record systems to connect patients, providers, pharmacies, clinics, hospitals, payers, and producers through a secure private network that operates in real-time at the point of care on-line or off-line.
