Abstract: Embodiments of this application provide a method and system for measuring motor damping. In the method for measuring motor damping, a driving signal is generated to drive a to-be-tested motor to operate, and at a cut-off moment of the driving signal, the to-be-tested motor enters a free damping state and a turn-off signal is generated at this moment to cut off a test circuit of the to-be-tested motor. In this way, an acceleration of the to-be-tested motor having the test circuit cut off and in the free damping state can be acquired, and damping of the to-be-tested motor is obtained by using the acceleration of the to-be-tested motor having the test circuit cut off and in the free damping state, thereby realizing the measurement of the damping of the to-be-tested motor.

Abstract: A photographing method is disclosed. By implementing the method, an electronic device 100, for example, a mobile phone, may determine bone points of a hand of a user in an image by using a bone point recognition algorithm, and determine two gesture feature points from the bone points. Then the electronic device 100 may construct, by using positions of the two gesture feature points on a horizontal coordinate axis, a gesture vector representing a state of the hand (a palm or the back of the hand). Further, the electronic device 100 may determine a gesture vector of a subsequent image frame by using the same method. When recognizing that a direction of the gesture vector in the subsequent image frame is opposite to a direction of a gesture vector in an initial image frame, the electronic device 100 may determine that the user has made a hand flip gesture.

Abstract: Methods and embodiments of a high-performance parallel multi-literal matching algorithm called NeoHarry. A chunk of data comprising a character string comprising n bytes is sampled for a byte stream, and data in the sampled chunk are pre-shifted to create shifted copies of data at multiple sampled locations. A mask table is generated having column vectors containing match indicia identifying potential character matches. A look up of the mask table at multiple sampled locations using the pre-shifted data is performed for a target literal character pattern. The mask table lookup results are combined to generate match candidates and exact match verification is performed to identify any generated match candidates that match the target literal character pattern. NeoHarry uses a column-vector-based shift-or model and implements a cross-domain shift algorithm under which character patterns spanning two domains are identified.
