The invention relates to a device for detecting and localising objects. The inventive device comprises a 3D camera for recording three-dimensional situation images of an area to be monitored; first means for evaluating the three-dimensional situation images using suitable object detection methods for determining an object in the area to be monitored and the position of the object in said area; a 2D camera for recording two-dimensional situation images of the region in the area to be monitored in which the position of the object has been determined; and second means for evaluating the two-dimensional situation images using suitable object detection methods for redetermining the object in the area to be monitored.

Apparatuses, methods and systems related to an improved golf data collecting and golf club notification system. The system reminds golfers when a club has been mistakenly left behind on the golf course and notifies the golfer when a golf club or clubs are in or out of the golf bag. The system can notify a golfer if a club or golf bag has been removed without authorization. In one preferred embodiment an apparatus that attaches to a golf club includes dual light sensors—one light sensor configured as a switch and one light sensor configured as a light meter. Algorithms make use of the light sensor data to determine whether a golf club is in or out of a golf bag.

The invention provides a device and method integrating gesture recognition and ultrasonic tactile feedback. The device integrates a functional unit comprising a camera, an illumination unit and an ultrasonic spray head assembly inside gloves, feeds back the hand operation in real time, achieves accurate identification and tracing to the hand actions of a user and converts tactile information fed back into forces or force moments directly acting the hands of the user, so that an operator can produce a real touch feeling in a virtual environment, and meanwhile touch feeling at multiple angle and strengths can be also simulated, the gesture recognition speed and accuracy are improved, and the fidelity and immersion degree of virtual reality experience are increased. The invention also relates to application of the device integrating gesture recognition and ultrasonic tactile feedback in virtual reality, augmented reality and mixed reality.

A system for and method of obtaining rotation information is disclosed. The method comprises capturing a plurality of patterned images from a plurality of locations, correlating the plurality of patterned images to generate sets of linear differences, and using the sets of linear differences to generate the rotation information. Preferably, the plurality of locations comprise a first part of a fingerprint swipe sensor and a second part of the fingerprint swipe sensor, each part configured to capture a part of a fingerprint image. Each part captures a part of the fingerprint image at two positions and correlates the parts at the two positions to determine one set of linear differences. Together, the sets of linear differences are used to calculate the rotation information, which can be used to emulate a rotational device such as a steering wheel, a joystick, or a navigation bar.

The invention provides a covering method of a map self-established by a mobile platform in an unknown region, wherein a virtual map is established in advance. The method comprises the following steps of: (1) when the mobile platform enters the unknown region, enabling the current position of the mobile platform to correspond to a subregion in which the original point of the virtual map is arranged; (2) marking the subregion corresponding to the current position of the mobile platform as a traversed subregion and marking other subregions as non-traversed subregions; (3) marking the non-traversed subregion adjacent to the traversed subregion as a target subregion; (4) moving the mobile platform to the region corresponding to the target subregion; (5) marking the subregion corresponding to the current position of the mobile platform as the traversed subregion, and determining a target subregion from the non-traversed subregions adjacent to the traversed subregion; and (6) repeating the step (4) and (5) until no target subregion exists. The method provided by the invention is simple in realization, high in converge rate and capable of reducing the repeated coverage rate of the mobile platform in the unknown region.

In a self-directed dust cleaner with surveiling function, when an object sensor senses existence of an object supposed as an intruder, a main controller controls that a driving apparatus to rotate a movable body to orient a lens of an imaging apparatus to the object. The imaging apparatus takes a picture image including the object, and an image data outputted from the imaging apparatus is transmitted to a telephone communication apparatus via a wireless LAN and a LAN cable. The telephone communication apparatus calls a mobile equipment of a user so as to transmit the image data taken by the imaging apparatus. Judgment whether unusual situation such as an intruder has occurred or not is entrusted to the user, so that an algorithm executed in the main controller becomes simple.

The invention discloses a method for measuring the diameter of a non-contact forging on line by using laser. A pair of parallel linear guide rails arranged at equal altitude on the two sides of the forging is used in the method. The method is characterized in that: a laser transmitter is arranged on one guide rail, a laser receiver is arranged on the other guide rail, the laser transmitter and the laser receiver are driven to travel by two stepper motors respectively, the positions of the laser transmitter and the laser receiver are kept synchronous during the travel, the distance between the tangent point of the laser and the section circle of the forging can be computed quickly through the travel distance of the stepper motors and the connection and interruption of signals of the laser receiver, so that the diameter size of the forging can be obtained. The method has the advantages that: two mutually independent linear guide rails are adopted, so that the diameter of the forging such as a spindle of a windmill generator and metallurgic rollers in a wider range can be measured by selecting a proper guide rail length; measuring staff are not required to contact high-temperature environment, and manual measurement is avoided, so that the diameter of the current forging can be obtained quickly, precision is high, the shortcomings of long time and large error of the manual operation are overcome, and forging speed and forging precision are improved; the shortcoming of reserving relatively large cold processing allowance according to experience is effectively overcome, the allowance consumption of the forging is reduced, and the energy conservation and consumption reduction are realized.
