A vascular closure device comprised of a sheath-delivered expandable, umbrella-like device with structural radial members with terminal and non-terminal hooks that engage the vessel wall. Unlike other vascular closure umbrella-type devices that effect closure by opening of the umbrella to cover an opening, the present invention effects closure of the aperture with closure of the umbrella. The closure can be maintained by a retainer lock that slides down the members, causing contraction, bringing the members into a compressed configuration (e.g., a parallel orientation of linear members) and the wound edges together, permitting immediate vascular closure and healing of the blood vessel. The device can be delivered and recovered by an intravascular sheath.

There is disclosed a sanitary tampon including an absorber including: an absorbent layer made of an absorbent fibrous material; and a hydrophobic liquid-permeable layer covering the absorbent layer. The absorber is formed firstly into a flat shape and then into a column shape. The absorbent layer forming the flat absorber is formed with a plurality of small recesses which open in the surface of the absorbent layer and extend into the absorbent layer.

A partial stroke testing system for online testing of emergency shut-off valve, said system is designed for implementation on an emergency shut-off valve with a main solenoid with manual reset, main solenoid valve, quick exhaust valve and a pneumatic actuator connected to a source of pressurized air supply for opening and closing the said emergency shut-off valve and the said shut-off valve normally movable between a fully open and fully closed position. The system also include control means programmed into the plant emergency shutdown system controller for initiating electrical signal for initiating a test and for enhancing the bleed rate from the said pneumatic actuator in the event of a emergency trip signal. Test means for testing the said emergency shut-off valve without fully closing the emergency shut-off valve in response to signal from the said control means is included in the system. The said test means, controlled by the said control means, include a second solenoid and a second solenoid valve for bleeding off pressurized air to thereby move the said emergency shut-off valve from full opened position to partially closed position. Means for limiting the movement of said emergency shut-off valve to a partially closed position because of the bleeding of pressurized air is included in the system. The system also includes an isolation valve for isolating the said test means for maintenance purpose.

The invention relates to an intelligent lamp control method and device. The method comprises that present state information of a terminal is obtained; whether the terminal is in a preset state is determined according to the present state information; when the terminal is in the preset time, whether present time is in a preset time period is monitored; and when the present time is in the preset time period, a control instruction is sent to an intelligent lamp and used to control the work state of the intelligent lamp. According to the technical scheme of the invention, the intelligent lamp can be rapidly automatically switched on or off by monitoring the state and time of the terminal, and convenience is provided for users.

An exemplary device and method for providing electric service are disclosed. The exemplary device may provide construction power during the construction of a facility and permanent power at the facility thereafter. The electric service device, when energized at a construction site, is operable to provide construction power through an electrical outlet at the device during construction of the facility and to provide metered or unmetered permanent power at the facility thereafter.

Microneedle device is provided, which include microneedles that can be easily inserted into skin and dissolve or swell in skin. The microneedle devices comprise a substrate and cone-shaped or pyramid-shaped microneedles for skin insertion set on the substrate. The microneedles for skin insertion contain over 50 weight percent of one or multiple biomaterials chosen from chitosan, collagen, gelatin, hyaluronic acid, and they are fabricated from the materials that can dissolve or swell in the body.

A device for injecting fuel into the combustion chamber of an internal combustion engine including a high-pressure storage chamber, a pressure booster, and a metering valve. The pressure booster includes a work chamber and a control chamber separated from one another by an axially movable piston. A pressure change in the control chamber causes a pressure change in a compression chamber of the pressure booster. The compression chamber acts upon a nozzle chamber in the nozzle body. A pressure relief valve (40) is in a control line between the control chamber of the pressure booster and a 2 / 2-way metering valve, the pressure relief valve includes a valve body that acts upon at least one hydraulic chamber and can be made to communicate with the pressure prevailing in the high-pressure storage chamber.

A device for catching insects is provided which includes an elongated member with first and second distal portions, an insect trapping head mounted on the first distal portion, and an actuating mechanism. The insect trapping head includes a first member and a second member pivotally mounted with respect to each other such that one of the members is moveable from about 0 to about 340 degrees relative to the other member, and preferably to about 270 degrees relative to the other member by activation of the actuating mechanism. When in the closed position, the first and second members define a rigid compartment such that the insect can be trapped between the first and second members. Preferably, a sticky surface on at least a portion of the interior of the compartment maintains the insects within the compartment.
