Abstract: A press-trigger fingerprint sensor module is disclosed, comprising two embedded switches, a sensor panel and a fingerprint recognition processor. When the user puts the finger in predetermined position over the sensor panel, the first switch is activated. The first switch sends out a high signal to have power connected to the fingerprint sensor. Without changing the position of the finger, the pressure being exerted perpendicular to the panel surface is transferred to the second switch, which then senses the presence of the finger and captures an image. The fingerprint recognition is performed subsequently. This sensor switch mechanism enables the system to obtain fast and high resolution images for fingerprint recognition. The smaller size of the fingerprint sensor not only reduces the power demands, but also breaks through the size barrier for encouraging more applications on mobile device.

Abstract: An electrostatic discharge circuit includes at least an electrostatic discharge zener diode, an NMOS transistor, and a PMOS transistor. The electrostatic discharge zener diode is used for lowering the breakdown voltage and making the electrical current discharge through it, thereby preventing the circuit device from burning out and greatly enhancing the function of electrostatic discharge protection.

Abstract: The present invention provides a sealing device and method for an ink cartridge. First, the ink cartridge and a sealing film are placed in an airtight chamber isolated to the atmosphere. Second, a decompression mechanism is used to draw the air off the airtight chamber until the air pressure in the airtight chamber is reduced to a pre-determined pressure. Finally, a sealing mechanism is used to seal the sealing film onto the ink cartridge.

Abstract: The ink cartridge comprises a container formed with an inner space and a port enveloped by an annular flange, a sealing mechanism used to fit in the annular flange, and an ink supply needle used to connect the inner space and output the ink. Pluralities of capillary portions are formed on the inner sidewall of the port so as to keep the filter with ink. A positioning hole indented from one end of the sealing mechanism is used to align the ink supply needle, and a recess is provided at another end of the sealing mechanism so as to connect the inner space of the container. When the sealing mechanism has been fully inserted with the ink supply needle, the sealing mechanism clamps the ink supply needle and the ink received in the container can be smoothly transmitted via the ink supply needle. When the ink cartridge is pulled out of the ink supply needle, the piercing hole of sealing mechanism is rapidly converged and sealed the port, and then the stored ink can be kept in the container with no leakage.

Abstract: An electric outlet assembly having multiple receptacle and contact holder sets mounted in a bottom shell and a top cover shell and adapted to receive electric plugs, the receptacle and contact holder sets each including a contact holder mounted in the bottom shell, three annular metal contact plates concentrically mounted on the contact holder and respectively connected to respective metal contact strips in the bottom shell, and a rotary receptacle mounted in a respective hole on the top cover shell corresponding to the contact holder and rotatable relative to the contact holder, the rotary receptacle having three plug holes, and three metal contact terminals respectively mounted in the plug holes at a bottom side and disposed in contact with the annular contact plates, the metal contact terminals being maintained in contact with the annular metal contacts upon rotary motion of the rotary receptacle relative to the contact holder.

Abstract: A swivel electric plug includes a base block having three annular terminal grooves concentrically provided in a recessed surface and a coupling groove around the recessed surface. Three annular metal plates are fastened in to the annular terminal grooves and connected to a respective wire in an electric wire being fastened to the base block. A circular cover plate is rotatably mounted on the recessed surface of the base block, the circular cover plate having a peripheral bottom coupling flange coupled to the coupling groove on the base block and holding two metal blades and a grounding prong. The metal blades and the ground prong each have an inner contact end respectively disposed in contact with the annular metal plates in the annular terminal grooves of said base block.

Abstract: A safety plug which includes a first metal contact plate and a second metal contact plate respectively connected to the two conductors of an electric wire, and a first metal blade and a second metal blade for connection to an electric power outlet. A cartridge fuse is connected between the second metal contact plate and the second metal blade. A switch is controlled to force the first metal contact plate into contact with the first metal blade to close the circuit. A base is mounted within a housing to hold the above members therein which has a rear panel and two plug holes on the rear panel for the insertion of an external electric plug for connection the first metal blade and the second metal blade, and a slide controlled to close/open the plug holes of the rear panel.

Abstract: A lamp socket including a socket body to hold a lamp bulb, a socket cap fastened to the socket body to hold down the electric wire, a central metal contact plate and side metal contact plate fastened to the socket body to connect the tip contact and ring contact of the lamp bulb to a respective conductor in the electric wire. The side metal contact plate has a longitudinal projecting spring strip raised from one side and then turned longitudinally downward toward the orifice of the socket body, which projecting spring strip is disposed in contact with the ring contact of the lamp bulb to give it an inward pressure when the lamp bulb is threaded into the socket body.

Abstract: A double-functional faucet structure including a water discharging tube communicated with a water supplying opening of a water supplying tube and a stepped hollow cylindrical valve shaft fitted in the water supplying opening. The interior of the water discharging tube is divided into a small passage and a large passage and the valve shaft is formed with a first water inlet and a second water inlet which are respectively communicated with the small and large passages of the water discharging tube. A switch handle is operated to alternatively discharge the water from the small passage at a reduced amount or from the large passage at a normal amount. A nozzle is disposed in a free end of the small passage, making the water flow out therefrom in a fog pattern.

Abstract: A faucet spout including a sleeve member having a lower water exit, a core member having a closed end, a filtering screen, a resilient adapter fitted onto a faucet and a cap member. The core member is disposed in the sleeve member with the closed end facing the water exit of the sleeve member. The filtering screen is disposed in an inner insert groove of the sleeve member above the core member. The resilient adapter is disposed on an inner step section of the sleeve member. The cap member is screwed on an upper end of the sleeve member to associate the resilient adapter with the sleeve member. When the faucet is opened, the water flowing into the sleeve member is more than the water flowing out of the sleeve member so that the water accumulates therein and creates turbulence and back pressure, making the resilient adapter more firmly engage with the faucet without easily detaching therefrom. The water under pressure will be injected from the water exit of the sleeve member in fog pattern.

Abstract: The invention described herein is a mechanical device that appearing uncrowded with lines, numbers, and other markings, depicts the sun's daily path and gives sunlight information, for any interested latitude, date, and time.A major dial is rotated on a base according to the latitude; a sun-path slider is slid on the major dial according to the date. Then the device depicts a two-dimensional, elevation view of the sun's daily path, as a straight line, through all or some of these five zones in the sky: direct sunlight; civil, nautical, and astronomical twilights; and night.The depicted sun's daily path gives the following sunlight information: the directions and times of sunrise and sunset; the times of the beginnings and endings of the twilights. On the depicted sun's daily path, the sun's position, indicated by a sun-position slider according to the time, gives solar energy quantities and the sun's angular height on the base and the sun's direction on a minor dial.
