    Abstract: A pneumatic actuator air flow control system includes a pneumatic rotary actuator (PRA) and a solenoid air flow control valve (SAFCV). The PRA contains an air reservoir and a vane housing allowing pressurized air to rotate an air-driven vane. The SAFCV includes a flow control valve body (FCVB), a pilot solenoid valve (PSV) and a switch system, wherein the FCVB and the PRA can be connected to direct the pressurized air into the air reservoir, and the PSV is used to control the pressurized air in and out of the PRA to change the vane's rotation movement in the vane housing. Additionally, the switch system allows users to switch between a double-acting and fail-safe operation. When there is no pressurized air and/or electrical power and if an emergent need to open or close the valve, a manual override in the PSV can be used without further installation of a declutchable manual gear operator or external piping when there is no pressurized air and/or electrical power.

    Abstract: A wireless client device is associated with an access point in an association having a value for a listen interval parameter. The wireless client device determines, according to predefined considerations, a different value for the listen interval parameter, and declares the different value for the listen interval parameter in a wireless transmission to the access point. The listen interval parameter specifies a number of beacon intervals that can pass from a time the wireless client device listens for a beacon frame from the access point before the wireless client device listens for a next beacon frame from the access point.

    Abstract: An improved structure of a central shaft in a pneumatic actuator comprises an actuator having an actuator chamber; a vane which is hingedly located at a shaft hole of the actuator. The central shaft is cylindrical and short, and the short central shaft has a through hole which is a through octagonal opening symmetric to a center thereof. It can be easily processed and precisely aligned. The advantage of the short central shaft is that the actuator itself can connect to non-pressured sources such as an upper and lower central shafts, and connect to different inserting drivers to form a central shaft as a unit in the pneumatic actuator to directly connect to a central shaft of a valve or indirectly through a connecting bracket instead of using a conventional connecting coupler. The octagonal opening provides alignment positions at every 45 degrees for the upper and lower central shafts to increase diversities of usage.

    Abstract: In one embodiment, an apparatus comprises a first clocked storage device operable in a first clock domain corresponding to a first clock signal. The first clocked storage device has an input coupled to receive one or more bits transmitted on the input from a second clock domain corresponding to a second clock signal. The apparatus further comprises control circuitry configured to ensure that a change in a value of the one or more bits transmitted on the input meets setup and hold time requirements of the first clocked storage device. The control circuitry is responsive to a sample history of one of the first clock signal or the second clock signal to detect a phase relationship between the first clock signal and the second clock signal on each clock cycle to ensure the change meets the setup and hold time requirements.

    Abstract: An actuator structure includes two half cylinders made respectively from the same mold and the two half cylinders engaged with each other to form an actuator. The actuator has an air reservoir chamber and a vane chamber dividing by a dividing unit, and the vane chamber has a vane inside. An O-shaped ring is formed around the vane and an elastic stopping edge is formed protrudingly from the O-shaped ring and linearly contacted an inner surface of the actuator. The volume ratio of the air reservoir chamber and the vane chamber is about three to one, and a channel groove is formed at an interface of the two half cylinders to connect an air inlet hole and a left side and a right side wall of the actuator. A fail-safe or dual-movement control structure is formed to control the direction of air supply to drive the shaft to rotate toward a predetermined direction, or utilizing the compressed air in the air reservoir chamber to force the vane to restore to its original position.

    Abstract: An auction method for specifying catalog contents for packaging and pushing to an electronic auction. The auction method is implemented in an electronic commerce exchange. The auction method includes the steps of specifying catalog contents for packaging for an auction operation hosted on the electronic exchange. Initial terms for the sale of the contents are then specified. The auction is then automatically initiated using the previously specified contents and the previously specified terms. The auction proceeds with the receiving of bids for the contents from remote bidders. The bids are received via a distributed computing network into which the electronic commerce exchange is communicatively coupled. A winning bid is selected by determining a most competitive bid out of the bids received for the contents. A sale of the contents is then completed based upon the terms of the most competitive bid.
