  • Patent number: 11960296
    Abstract: A method executable by an autonomous mobile device includes moving in a work environment, obtaining environmental data acquired by a sensing device, and determining whether the sensing device is in a suspected ineffective state based on the environmental data. The method also includes based on a determination that the sensing device is in the suspected ineffective state, rotating at a same location for a first predetermined spin angle. The method also includes obtaining an estimated rotation angle based on one or more motion parameters acquired by a dead reckoning sensor, comparing the estimated rotation angle with the first predetermined spin angle, and based on a determination that a difference between the estimated rotation angle and the first predetermined spin angle is greater than a first predetermined threshold value, executing escape instructions to move backwardly for a first predetermined distance and move along a curve or a folded line.

  • Publication number: 20240068856
    Abstract: A device for measuring volume of spherical tanks, includes a base, four supporting rods, a driving mechanism, a rotating disc and a counterweight mechanism. The base is provided with a first through hole and a circular fixing base with a second through hole. The supporting rods are circumferentially provided on the fixing base, with a sliding rod slidably provided at the lower side. An outer end of the sliding rod is provided with a limiting plate. The driving mechanism can drive the sliding rods to move simultaneously in radial directions. The rotating disc with a third through hole is arranged on the fixing base, and is rotatably provided with a reel around which a steel tape is wound. A free end of the steel tape is provided with a balancing disc whose opposite sides are provided with laser rangefinders. The counterweight mechanism can keep the balancing disc stable.

  • Publication number: 20230404434
    Abstract: According to the techniques herein, one or more sensors coupled to an aligner are used to sense one or more physical qualities of the aligner to determine whether the physical qualities indicate that the aligner material has relaxed and has, e.g., reduced the force systems applied to teeth and/or that the teeth movement for the stage has slowed down. The sensors may provide a signal that represents whether or not the physical qualities fall below a threshold value. A treatment plan may be modified if needed. These techniques have the potential to make treatment plans faster and more effective by speeding up some stages while making sure some, perhaps other, stages are implemented only after the teeth are near the appropriate position.

  • Patent number: 11672539
    Abstract: Implementations of the present disclosure relate to apparatuses, systems, and methods for anastomosing vascular systems in medical procedures. A pair of similar or identical coupling devices may be disposed at the ends of two vessels, either natural or synthetic. The coupling devices may be capable of hermaphroditically connecting to one another to provide a simple and secure connection which promotes growth of the vessels between the bio-absorbable coupling devices.

  • Publication number: 20220160470
    Abstract: The disclosure provides resins, polymeric materials, and devices incorporating force probes. Advantageously, the force probes emit an emission useful for determining the amount of force or stress applied to a material incorporated with force probes. Further, the present disclosure provides methods of detecting forces and stress applied to force probe incorporated materials. Materials such as orthodontic appliances comprising force probes possess particular advantage and utility as measurement of the emission of the orthodontic appliance(s) from a patient can aid in evaluating treatment progress.
