Abstract: The present disclosure provides a verification method for distinguishing a man from a machine, wherein the method comprises: S1: receiving trajectory information input by a terminal; S2: comparing the trajectory information with a preset trajectory; S3: judging whether verification passes at least from dimensionality of a comparison result of the trajectory information and the preset trajectory. As compared with the prior art, the verification method and apparatus for distinguishing a man from a machine in the present disclosure may recognize user identity through simpler operation, and particularly applied to the mobile device, may bring about better user experience, and meanwhile exhibit very high security and difficulty in cracking the machine.

Abstract: A fan control system for a fan on a motherboard includes an I/O controller installed on the motherboard and a control circuit electrically connected to the I/O controller. The fan includes a motor and a rotation speed detecting chip. The I/O controller outputs a rotation speed control signal and a pulse width modulation (PWM) signal. The rotation speed detecting chip detects a rotation speed of the fan, and outputs a rotation speed feedback signal according to the rotation speed of the fan. The I/O controller receives the rotation speed feedback signal, and adjusts a duty cycle of the PWM signal accordingly to change the rotation speed of the fan. The control circuit receives the rotation speed control signal, and outputs a fan driving signal accordingly. The motor receives the fan driving signal, and drives the fan to rotate in a direction according to the fan driving signal.

Abstract: A heat dissipating apparatus includes a base and a heat pipe. A plurality of fins partially overlaps the base; the heat pipe comprising a first body, a second body and a third body, the second body connected between the first body and the third body; the first body is secured between the plurality of fins and the base, the third body is secured to the plurality of fins, and the second body is located in a first corner between the base and the plurality of fins.

Abstract: An in-channel marketing and product testing system having a purchase environment module with instructions for generating a virtual purchase environment comprising a plurality of competitive products. The system also includes a panelist interface configured to receive panelist input, wherein the panelist interface is arranged in selective communication with the purchase environment module to receive and display the virtual purchase environment. The system might also have a research module in communication with the purchase environment module and the panelist interface. The research module is configured to enable selective control and manipulation of the virtual purchase environment generation and to receive panelist input from the panelist interface to facilitate analysis of test data and preferences.
