Abstract: A controller assembly functioning as a joystick includes a driving unit, a sliding member, a potentiometer, and a controlling module. The driving unit includes a driving mechanism, a worm, and a worm wheel, the worm wheel connected to the sliding member. Through the worm, the driving mechanism rotates the worm wheel, causing the sliding member to move up and down only. The potentiometer detects rotation of the worm wheel, the controlling module obtains movement accordingly of the sliding member. The controlling module obtains a user's operating force applied to the driving mechanism, and compares the positional information and the operating force information with preset values to obtain comparison results. The sliding member is driven to move according to the two comparison results. An electronic device with the controller assembly is also disclosed.

Abstract: A method of detecting and identifying postures and gestures of a human user generates a reference model from a reference image and obtains an image of action or gesture being performed. The image is of a user and his flexible and hand-held portable device, and the image comprises a second identification feature. A state of a second feature of the second identification feature in the reference model can generate posture identification. The state of the second feature comprises size, shape, and location of the second identification feature in the hands of the user. A portable device and a non-volatile storage medium of a computer are also disclosed.

Abstract: An electrically-contactless joystick includes a housing, a handle, a first limiting member, a second limiting member, an elastic member, a magnet, and a magnetic sensor. The handle extends through the housing. The first limiting member and the second limiting member are fixed to the handle and movably clamped with the housing. The elastic member is connected to each of the first limiting member, the second limiting member, and the housing. The second limiting member abuts against the handle. The magnet is fixed to either the handle or the housing, and the magnetic sensor is fixed to the other. A terminal device is also provided.

Abstract: A system and a method for determining a parking space are provided. The method includes: obtaining parking space information within a range where a vehicle is located, the parking space information including parking lot map data; analyzing an object in individual parking space in the parking space information and generating object information of the object of the individual parking space; and using the object information and the parking space information to calculate a spatial relationship between the object in the individual parking space and a parking space where the object is located, and determining that the parking space is an available parking space if the spatial relationship satisfies vehicle body information of the vehicle. Therefore, the vehicle can determine an available parking space before passing it, and can further choose a better parking space.

Abstract: A parking spot detection system is provided with a detection unit, a map database and a processing unit. The detection unit acquires position data and intensity data of a plurality of data points in an environment space. The map database provides map information. The processing unit is coupled to the detection unit and the map database and determines whether a geometric shape formed by adjacent data points is of a parking space according to the intensity data of the data points; and if the geometric shape is determined to be of the parking space, the processing unit further integrates the geometric shape and the position of the parking space into the map data according to the position data of the data points.

Abstract: An automatic vehicular sensor adjustment method includes: a step of installing a vehicular sensor with a posture on a vehicle body, the posture being defined by at least one of a distance, an inclination and a facing angle of the vehicular sensor with respect to the vehicle body, the distance including a height and a position of the vehicular sensor with respect to the vehicle body; a step of, according to an environmental scenario in which the vehicle body encounters, determining whether or not there is an adjustment need, the environmental scenario including a single event or multiple events; and, a step of, according to the adjustment need, adjusting the posture of the vehicular sensor. In addition, an automatic vehicular sensor adjustment system is also provided.

Abstract: A noninvasive stereotactic assembly for guiding an instrument to a target within a patient's head includes a head frame subassembly and an instrument positioning subassembly. The head frame subassembly is secured to a skull in the patient's head to determine an X-axis and a Y-axis of a three-dimensional coordinate system. According to the coordinate of the target in the three-dimensional coordinate system, ring members, a movable bracket, a swivel member, and an instrument holder of the instrument positioning subassembly are displaced by predetermined angles to guide the instrument toward the target.
