Abstract: The micro supervisory system of the invention includes a casing, an image capture module, a display device, a gas generator, and a wireless transmission module. The image capture module is disposed in the casing, and captures an image and then generates an image signal. The display device receives the image signal and then generates a driving signal. The gas generator is disposed in the casing, and receives the driving signal and then generates a gas for anti-riot scenarios. The wireless transmission module receives and then transmits the image signal to the display device. Meanwhile, the wireless transmission module receives and then transmits the driving signal to the gas generator. Therefore, the tear gas can be released from the gas generator and is used for expelling people. The micro supervisory system of the invention can be applied to military spies, anti-riot supervision, and calamity supervision.

Abstract: The present invention provides a digital camera DIY wireless photo print device. The device comprises a billing box, a wireless image-receiving unit, a processor, a monitor, and a photo printer. Wherein, the processor includes a plurality of control and IrDA protocol-processing programs to control the other units that are connected to the processor. The billing box provides a variety of payment methods. The monitor displays the two-way communication between the device and the user, and also displays the status of the image file transmission. The wireless image-receiving unit receives the optic signal of the image file, processes the photo-electronic transformation, and outputs an image file data to the processor. The processor controls the photo printer to print and output the photo.

Abstract: An electric soldering iron has an elongated hollow handle casing having a tubular hollow holder extending from one end thereof and supporting a soldering bit heated by an electric heater within the holder. A forked suction pipe is secured to the holder and includes a main pipe having an intake port at one end disposed adjacent to the soldering tip and an outlet port at its other end connected to an induced-draft fan assembly through a flexible air pipe. A branch pipe of the suction pipe extends laterally from the main pipe and has an intake port connecterd to the interior of the casing through a heat resistant hose. Actuation of the induced-draft fan causes soldering fumes generated at the tip to be drawn into the main pipe and for cooling ambient air to be drawn through the casing from an inlet at its other end to remove excess heat from the casing.
