  • Patent number: 11932062
    Abstract: A tire surface managing method, comprising: emitting detecting light to a target object on a surface of a tire; receiving reflected detecting light from the target object and from the surface adjacent to the target object; determining whether the target object protrudes according to a distance calculated according to the reflected detecting light from the target object and a distance calculated according to the reflected detecting light from the surface; determining whether the target object forms a hole on the surface according to the distance calculated according to the reflected detecting light from the target object and the distance calculated according to the reflected detecting light from the surface; receiving the reflected detecting light from the surface to calculate a width of the hole on the tire; and activating a protection mechanism for a vehicle comprising the tire if the width is larger than a width threshold.

  • Patent number: 9859487
    Abstract: A motor includes a rotor module and a stator module. The rotor module includes electro-active polymer modules which change their physical size depending on electrical activation or deactivation. The stator module includes a base and a plurality of magnets mounted on two fixing plates of the base. The rotor module comprises a rotor and a coil. Precise displacement by the motor is obtained by electrically activating or deactivating the electro-active polymer modules.

  • Patent number: 9774238
    Abstract: A linear motor includes a stator and a rotor. The stator includes two opposing plates, a spacing plate positioned between the plates, and a plurality of permanent magnets mounted on the two plates and spaced from each other. The rotor includes a coil portion and an assembly block. The coil portion is positioned between the two plates, and the assembly block is connected to the coil portion and next to the plates. The spacing plate defines a slide groove, and the coil portion includes a plurality of balls mounted at one surface toward the spacing plate. The plurality of balls is partially received in the slide groove in the sliding way.

  • Publication number: 20160349758
    Abstract: A logistics system applies to a logistic vehicle and a plurality of production equipment is provided. The logistic system includes a position confirming module, a calculating module, and a driving control module. The position confirming module is configured to determine a current position of the logistic vehicle based on strengths of the first signals and a relationship recording relationships between first signal strengths and distances between the logistic vehicle and the production equipment. The calculating module is configured to calculate a first optimal path for the logistic vehicle from the current position to the production equipment which transmitted a second signal indicating finished machining based on a map including the plurality of the production equipment and the current position of the logistic vehicle. The driving control module is configured to control the logistic vehicle to move according to the first optimal path. A logistics method is also provided.

  • Publication number: 20110201529
    Abstract: The present invention provides a system for analyzing and screening disease related genes from microarray database. After normalizing the collected microarray datasets and related experiment data by using pre-processing unit, the relative important feature vector can be systematically extracted by the feature selection unit. The maximal likelihood discriminate rule of classification unit calculates probability statistics of the classification and diagonal quadratic discriminant analysis module is used to decide classification and set up disease prediction module. Also, the generalized rule induction information statistics calculation module of rule extraction unit is used to obtain organized information statistics and information theoretic rule induction algorithm module is employed to generate best relationship rule and associate rule module can be set up.
