Abstract: A method for detecting azimuthal angle of a heat source includes a preparing step and a detecting step. The preparing step includes: detecting a unit period (Tc) by rotating a target positioning portion through one circle, and aligning the target positioning portion with an aligning member. The detecting step includes: driving the target positioning portion to rotate. The position of the aligning member defines an initial azimuthal position. When an infrared signal emitted from the external heat source is transmitted into an infrared sensor via the target positioning portion, a transmitting time is defined as a time point (Ts) of the heat source, and an angle between the target positioning portion and the initial azimuthal position is defined as an azimuthal angle (?x) of the heat source, in which ?x=(Ts/Tc)×360°.

Abstract: The present invention primarily relates to a method for initiating and controlling a lighting equipment by detecting and determining through an algorithm whether a flicker of light may occur during the period of initiating or dimming the lighting equipment. The method further calculates to obtain a current compensation ratio that the current level need be elevated to prevent the occurrence of flicker and performs a real-time compensation for the electrical current, when necessary. The method according to the invention will initiate the lighting equipment at an electrical current level used during a previous stable operation of the lighting equipment, so as to further prevent the occurrence of flicker of light during the initiation of the lighting equipment and achieve the energy saving purpose.

Abstract: Disclosed is a detection process performed in the detector, which is switchable between an active detection mode, where the detector actively monitors the surrounding area, and a passive detection mode. The data obtained by operation in the active detection mode for the first time are temporarily stored to serve as an initial environmental parameter. Subsequently, the detector operates primarily in the passive detection mode to determine whether or not a downstream device is to be activated, while switching intermittently from the passive detection mode to the active detection mode to thereby determine the activation or deactivation of the downstream device based on the result of comparing the detected value with the initial environmental parameter.

Abstract: A remote control security supervisory control apparatus includes a remote control device capable of performing remote control, at least one sensor to detect risky conditions in a surveillance scope and a system host to execute a security supervisory control system procedure. The remote control device can perform system alteration on the sensor at a remote site. The remote control device first outputs a wake-up signal to make the individual sensor to enter a setting mode from a sleeping mode; then the remote control device outputs a command signal to the system host through the sensor. The system host feedbacks a confirmation signal to the sensor to finish setting alteration of the security system procedure.
