Abstract: A liquid dispenser includes a hollow shank, a dispensing head longitudinally mounted to a first end of the hollow shank, a control device longitudinally mounted to a second end of the hollow shank and a sheath detachably mounted to the first end of the hollow shank for protecting the dispensing head after use. A passage is defined in one end of the hollow shank for communicating with an inner periphery of the hollow shank and the dispensing head such that the liquid contained in the hollow shank can flow into the dispensing head. The control device is provided to selectively close/open the passage for controlling the output quantity of the liquid dispenser.

Abstract: An actuator assembly having an operation indication function is disclosed. The actuator assembly includes an actuator, a controller and an indication lamp set. The actuator has a motor, a screw, and an extension rod, which has limit positions connected with a limit switch set. The controller controls the motor of the actuator to rotate clockwise or anticlockwise. The indication lamp set is settled on at least one point on a circuit between the actuator and the controller and electrically communicated with the limit switch set. Thereby, when the extension rod touches any of the limit positions and thus triggers the limit switch set, the indication lamp set illuminates to indicate that the extension rod of the actuator reaches the corresponding limit position.

Abstract: A holder device may be attached to a water outlet tube which is extended from a wall, without drilling holes in the wall, and includes a housing having an inlet attached to the water outlet tube, and two or more outlet ports for coupling to a shower head and a sprayer nozzle, a base having a spring-biased latch for clamping the pipe to the base, a seat slidably attached onto the pipe for adjustably and removeably supporting the sprayer nozzle. The housing includes a casing having a chamber for receiving a valve stem, and a spring-biased valve member received in the valve stem to control the water to flow out through the outlet ports of the housing, and a knob secured to the valve stem to rotate the valve stem relative to the casing and the housing.

Abstract: A football game machine includes a goal device divided into multiple strike areas that respectively indicates different score marks. Each strike area has multiple pressure sensor mounted therein. Two casing mounted to two opposite sides of the goal device. Each casing has an inner side having a series of photoelectric cells mounted thereon. The football game machine can calculate the speed of the flying ball by using the time difference of the photoelectric cells and the pressure sensor. A display device is mounted on the goal device for displaying the total scores and the speed of the flying ball. A ball recycle device is mounted in one of the two casings. A football is connected to the ball recycle device via a rope. The ball recycle device can recycle the ball when the game is finished and release the rope before playing the ball.

Abstract: A linear solenoid includes a pair of soft iron pole members which are in a spaced apart linear arrangement. A permanent magnet is attached to the end of a plunger which rides between the pole members. When a first of two electro-magnet coils is energized the plunger which is latched to one of the pole members is repelled to the opposite pole member and latched. When the second coil is energized the plunger returns to the original pole member and is latched.

Abstract: A releasing valve for an inflatable object has a body, a valve disk and a cap. The body is body and has a passage and a disk mount. The passage is defined through the body and has a bottom opening. The valve disk is attached securely to the bottom of the body to close the bottom opening of the passage and has a mounting end and a free end. The mounting end is mounted securely on the disk mount of the body. The free end is opposite to the mounting end. The cap is attached to the body around the bottom opening, holds the valve disk inside and has a stop. The stop selectively engages the free end of the valve disk when the valve disk being pushed away from the bottom opening for discharging air out from the inflating object via the releasing valve.

Abstract: A filter cup assembly includes a first cup having a one-way valve connected to a center of the underside of the first cup 10 and a filtering part is connected to the underside of the first cup. An adaptor is connected between the filtering part and a second cup. A presser includes a pressing plate connected with a rod, the pressing plate is inserted into the first cup to force contaminated water in the first cup to pass through the one-way valve, the filtering part and is collected in the second cup. All of the parts are threadedly connected to each other so that they can be separated individually. The first cup is sized to receive the second cup, the filtering part and the adaptor when not in use.

Abstract: This specification discloses a driving safety auxiliary network administration system and the method thereof. Vehicles in motion communicate with each other about their geographical locations and current moving states within a communication range. At least one of the vehicles in the communication range becomes the router of several other vehicles that are at dead corners of wireless communications. The router is responsible for transferring vehicle state signals of those vehicles out of direct communications between them. Therefore, all the vehicles in the communication range are not blocked by terrains, buildings or other vehicles. All of them are taken into account to assess and find possible dangerous vehicles. This technique can effectively solve the problem of dead corners in driving safety auxiliary network communications. Highly important packets can be immediately and reliably transmitted to the corresponding vehicles, providing efficient warnings.

Abstract: A doorway mounted horizontal bar includes a rod having two ends for attaching to two side moldings of a doorway, two frames attached to the end portions of the rod for supporting a tubular member, and two auxiliary supports each having a lower segment attached to the rod and each having an upper handle attached to the upper end of the frame for being grasped by the user, the lower segments of the auxiliary supports are each attached to the rod with a coupling device, and the handles of the auxiliary supports are each attached to the frame with another coupling device, the coupling devices each include a quick release fastening device for detachably securing the coupling devices and the auxiliary supports to the rod and the frames.

Abstract: A hair barrette includes two barrette members each having an outer head engaging end and an ear extended from an inner coupling end, and a coupling device includes two coupling members disposed above and below the ears and having two pivot axles for pivotally coupling the ears between the coupling members and for allowing the barrette members to be folded to an opened working position where the barrette members are opened and oppositely spaced from each other for forming or operating as a hair barrette device, and to be folded relative to each other to a folded storing position where the barrette members are engaged with each other for forming or operating as a hair clip device.

Abstract: A lock device includes a casing formed in a housing for rotatably receiving a rotary member which has an actuating finger and which is coupled to a handle with a driving shank, and a spring biasing device attached to the housing and engaged with the actuating finger of the rotary member for biasing the handle back to an original position and for biasing the actuating finger of the rotary member back to an original position when the handle is released, the spring biasing device is locked to the housing with a fastener to disengage the follower from the actuating finger of the rotary member when a spring biasing member is engaged between the handle and the housing to bias the handle back to an original position.
