Abstract: A heater alarm and control module includes a main processor of the heater alarm and control module, a heater alarm and control circuit, and a heater temperature controlling module. The heater temperature control module includes n heater temperature controllers. The main processor is connected to the heater temperature control module through the heater alarm and control circuit. The heater temperature controller includes an optically coupled solid-state relay including a light-emitting diode and a power switch; and a photocoupler including a light-emitting diode and a phototriode; and a microprocessor connected to the optically coupled solid-state relay and the photocoupler. The main processor provides a control signal to the heater temperature control module.

Abstract: A temperature controller includes a microprocessor, a temperature detector, a current detector, a control relay and an external interface. Wherein, the temperature detector detects a working temperature of a heater; the current detector detects a current value passing through a heating element; and the microprocessor determines an operating state of the temperature controller (102) according to a temperature and a current value received from the temperature detector and the current detector, and sends a control signal to the control replay, thereby controlling the operation of the heater so as to adjust the temperature. By means of the temperature controller, current measurement is added while temperature measurement is performed, so that an operating state of a heater can be correctly determined, thereby greatly improving the reliability of the temperature controller.

Abstract: Methods and apparatus are disclosed for navigation based on real-life video. A real-life navigation video segment for navigating from a starting point to an ending point may be compiled from pre-recorded real-life navigation video clips or portions of the pre-recorded real-life navigation video clips. The real-life navigation video clips used for compiling a navigation video segment may be chosen based on current navigation parameters such as the weather, time of the day. The compiled real-life navigation video segment may be played and synchronized with actual navigation.

Abstract: A snap block structure for racing type bicycle shoes includes a hard snapping plate, and a soft anti-skid pad mounted on the snapping plate. Thus, the snap block structure has an anti-skid pad mounted on the snapping plate to provide an anti-skid effect when touching the ground. In addition, the anti-skid pad is combined with the snapping plate rigidly and stably, thereby enhancing the strength of the snap block structure.

Abstract: A pedal assembly for a bicycle includes a pedal body, a pivot seat, and a bearing. The pedal body has a side provided with a pivot seat for mounting a single bearing, so that the position of the axial center of the pivot seat can be changed to reduce the distance between the force applying point of the user's foot and the axial center of the pedal body greatly. Thus, the force applying point of the user's foot is closer to the axial center of the pedal body, so that the rotation radius of the pedal body is closer to that of the crank of the bicycle, thereby saving the manual work and decreasing the centrifugal effect.

Abstract: A snap block structure for a pair of mountaineering bicycle shoes each having a bottom formed with two protruding spiked blocks and two threaded locking holes located between the two spiked blocks. The snap block structure includes a snapping member mounted on the bottom of each of the mountaineering bicycle shoes and having a top face integrally formed with a protruding block mounted between the two spiked blocks of each of the mountaineering bicycle shoes. Thus, the mountaineering bicycle shoes are available for a mountaineering bicycle pedal and also available for the road-use bicycle pedal by provision of the snap block structure, thereby enhancing the versatility of the mountaineering bicycle shoes.

Abstract: A pedal structure for a bicycle includes a pedal body, and an elastic clamping device. The elastic clamping device is mounted on each of the two opposite sides of the pedal body and includes a front binding plate, a rear binding plate, a pivot shaft, at least one torsion spring, an urging plate, and an adjusting bolt. Thus, the cleat can be mounted on and detached from the pedal body easily and conveniently, and can be clamped on the pedal body rigidly and stably by the elastic clamping force of the front binding plate and the rear binding plate.

Abstract: A racing type pedal includes a main body, a pivot hook, a limit member, an adjusting bolt, a press block, and two torsion springs. Thus, the movement of the adjusting bolt is limited by the limit member, and the movement of the press block is limited by the torsion springs, so that the adjusting bolt and the press block form a linear movement without deflection, thereby producing an evenly distributed shearing stress between the adjusting bolt and the press block, thereby preventing the adjusting bolt and the press block from being worn out due to an uneven shearing stress.
