Abstract: An optical housing for high power fiber components includes an upper cover, a lower base, and two isolating members. The upper cover includes a light-reflecting portion for containing the optical fiber and receiving and reflecting the light therefrom. The lower base is connected with the upper cover and includes a light-receiving portion which corresponds to the light-reflecting portion in position and surrounds the optical fiber, thereby receives the light from the light-reflecting portion. The isolating members are disposed between the upper cover and the lower base and located on two sides of the optical housing to prevent the leakage of light from the optical fiber.

Abstract: A reflective modulator which comprises a coupler, two diodes and two DC block units. The coupler has an input end used to output an output signal, an output end used to output an output signal, a first load end connected to one of the diodes and a second load end connected to another one of the diodes. The DC block units connect between the diodes and the coupler for DC blocking. A message signal is selectively inputted to both of the two DC block units for operating the state of the two diodes. The two diodes turn on when the message signal is large enough. The two diodes turn off when the message signal is not large enough. The two diodes are implemented by PIN diodes. A BPSK modulator using the reflective modulator and a quadrature modulator using the BPSK modulator is also introduced.

Abstract: The present application provides a wireless charging module and a modularized sensing device therewith. A first charging unit is disposed around the inside of the wireless charging module for wirelessly charging a sensing module. Without introducing a transmission line as an electricity transmitting medium, the sensing module can be directly disposed inside and charged by the wireless charging module, which improves flexibility of implementation. Further, since the first charging unit is configured to surround the inside of the wireless charging module shaped as a bowl structure, the sensing module can be simply disposed into the bowl structure and wirelessly charged by the surrounding first charging units, which saves the inconvenience of setting the sensing module to a specific location or area for stable wireless charging and increases effective charging angles.

Abstract: A screw clamping device includes a body, a pressing unit, a resilient unit, a clamping unit and a connecting unit. The body is a hollow-core cylinder, is subject to axial penetration of a screwdriver, and is movable axially in synchrony with rotation of the screwdriver. The pressing unit is disposed on the body and adapted to press against a surface of a working object. The resilient unit is disposed between the body and the pressing unit. The clamping unit is rotatably connected to the body. The connecting unit has one end connected to the pressing unit and the other end connected to the clamping unit. While the body is moving axially, the connecting unit drives the clamping unit to rotate and thereby clamp or loosen screws.

Abstract: A mobile rustproofing washing system includes a receptacle, a control module, a water supply module, a filtration module and a washing module. The receptacle is removably disposed on a mobile carrier. The control module is disposed in the receptacle. The water supply module is disposed in the receptacle and includes a front water tank and a rear water tank. The filtration module is connected to the front water tank and the rear water tank. The filtration module receives and filters water from the front water tank. The filtered water is stored in the rear water tank. The washing module connects with the rear water tank and receives water therefrom, so as to carry out a washing process. Therefore, the mobile rustproofing washing system is quick to mount/demount and easy to use, thereby having high mobility.

Abstract: An all-weather thermal-image pedestrian detection method includes (a) capturing diurnal thermal images and nocturnal thermal images of a same pedestrian and non-pedestrian object in a same defined block to create a sample database of thermal images, wherein the sample database comprises pedestrian samples and non-pedestrian samples; (b) performing LBP encoding on the pedestrian samples and the non-pedestrian samples, wherein complementary LBP codes in the same defined block are treated as identical LBP codes; (c) expressing the LBP codes in the same defined block as features by a gradient direction histogram (HOG) to obtain feature training samples of the pedestrian samples and the non-pedestrian samples; (d) entering the feature training samples into a SVM to undergo training by Adaboost so as to form a strong classifier; and (e) effectuating pedestrian detection by searching the strong classifiers in thermal images with sliding window technique to detect for presence of pedestrians.
