Abstract: The present application related to a camera system and a camera fill light method. The camera system establishes a wireless communications connection with a fill light, captures an original image by a camera in the camera system, and then transmits a first test light signal to the fill light such that a first flash is performed by the fill light. The camera captures a first light source image during the first flash period of the fill light. A fill light controller in the camera system compares differences of the brightness or the chroma of different image information and, after determining the present location of the fill light, calculates a dislocation result of the present location of the fill light and the best placement location of the fill light. The camera system yields the dislocation result to the photographer via a notification message.

Abstract: A fatigue alarm apparatus having a fatigue detector, a control unit and a stimulus alarm generator is illustrated. The fatigue detector detects whether a driver is drowsy. The control unit is electrically connected to the fatigue detector and the stimulus alarm generator. When the fatigue detector detects that the driver is drowsy, the stimulus alarm generator controlled by the control unit to generate two stimulus alarms having a rest time period therebetween, and then, after an interval period elapses, the control unit determines whether an alarming procedure of generating the two stimulus alarms is to be interrupted or repeated, wherein the rest time period is less than the interval period.

Abstract: An optical toy is disclosed. The optical toy includes a frame, at least one emitting part, at least one receiving part, a plurality of light guiding parts, and at least one power source. The frame includes a container and at least one containing structure. The emitting part is movably located on the containing structure. The emitting part includes at least one light source for emitting light. The receiving part is movably located on the containing structure. The receiving part includes a light sensor for sensing the light. The plurality of light guiding parts is located in the container for changing the direction of the light. The relative positions of the plurality of light guiding parts can be changed. The power source is located in the frame for providing power to the optical toy.

Abstract: The present disclosure relates to a mobile device provided with a camera module that is detachably received in a side of the device body. Particularly, the camera module is hidden inside the device body when not in use and can be drawn out from the side of the device body when in use. Since the camera module is not affixed permanently to the device, the detachable camera module can be used in small confined areas with expanded photo-capturing scope and angle.

Abstract: A multi-protection touch lock has a lock body and an unlocking panel connecting to the lock body. The lock body has a control mechanism, a locking unit connecting to the control mechanism, and at least one displaying unit connecting to the control unit, and at least one connection interface connecting to the displaying unit. The at least one unlocking panel has at least one transmission interface connecting to the at least one connection interface, and at least one operating unit connecting to the at least one transmission interface. The lock can be located at the predetermined position to control the door access, vehicle actuation and the use of electrical appliances. When unlocking, the unlocking panel comes to in contact with the lock and the correct password is input via the unlocking panel. After the unlocking action is completed, the unlocking panel is removed from the predetermined position.

Abstract: A light guide unit provided in this disclosure is used for performing a reversible optical conversion process on a light source. In an embodiment, the light guide unit is used for converting a planar light source into at least a linear light source, and then further to be converted into one point light source, while allowing beams emitted from the point light source to be guided and shot to a specific position by the use of a light-guiding element. Moreover, in another embodiment, the light guide unit is used for converting at least one point light source into at least a linear light source, and then further to be converted into a planar light source for emitting light. The light guide unit can be adapted for various applications, such as optical devices for illumination, entertainment, decoration or ornaments.
