Abstract: In at least some embodiments, a method comprises receiving an external card detection signal that indicates that a hot-pluggable card is coupled to a computer system and activating at least one reference clock signal of a scalable reference clock platform based on the external card detection signal. The method further comprises synchronizing clock signals embedded in data packets transmitted between the hot-pluggable card and the computer system with another clock signal based on the at least one reference clock signal.

Abstract: A method and apparatus are disclosed for allowing a plurality of network connectors to utilize a single network controller within a docking station or portable device. A switching device connects the plurality of network connectors with the network controller. By connecting the network connectors into the switching device, the docking station and the portable device require a single network controller to handle the network communication. The switching device enables the network controller to continue to operate without disrupting the portable device when the network connection is changed from the docking station to the portable device or vice versa. The method and apparatus are useful in reducing the complexity of the total system while increasing functionality.

Abstract: An air passageway obstruction device includes a frame structure and a flexible membrane overlying the frame structure. The frame structure is collapsible upon advancement of the device into the air passageway, expandable into a rigid structure upon deploying in the air passageway and re-collapsible upon removal from the air passageway. The flexible membrane obstructs inhaled air flow into a lung portion communicating with the air passageway. The device may be removed after deployment in an air passageway by re-collapsing the device and pulling the device proximally through a catheter.

Abstract: A gas-pressure regulator has a body formed with a gas inlet and a gas outlet defined therein, a diaphragm separating the body from the bonnet, a lifting rod extending downward from the diaphragm, a pair of parallel protrusions projecting upward from the inner bottom of the body, a pair of aligned recesses formed on the tops of the protrusions, a pair of threaded holes defined in the tops of the protrusions near the respective recesses, and a pair of screws formed with heads above the protrusions and shanks screwed into the threaded holes. The gas-pressure regulator also includes a control lever having a first end and a second end, with a pair of pins near one end thereof extending integrally and laterally from opposite sides of the control lever. The pins are placed in the recesses of the protrusions and retained therein by the heads of the screws, and the second end of the control lever is connected to the lifting rod.

Abstract: A rowing exercise machine comprises a base, a seat mounted on the base, two rowing rods pivotally mounted on the base, an actuating wheel having a shaft rod, two crank rods fastened at one end with the shaft rod, and a damping device.

Abstract: A computer-readable recording medium stores a method of modifying and masking output events of bi-directional signals specified in an event-format test pattern file for a semiconductor integrated circuit, wherein the process of masking and modifying output events does not require any manual operation.

Abstract: The present invention includes a main circuit and a circuit to be tested. An observation node and a control node are connected to the circuit to be tested. A pin is connected via an analog switch and a digital switch to these nodes. The test circuit controls the switch and input and output of test data. The test circuit has one bi-directional digital pin. A control signal and observation data are input to and output from an analog circuit through an analog test pin.

Abstract: A coupling device including a tubular member, a locking member engaged with the tubular member, a sleeve made of polymer which will become soft at at temperature between 240-300 degrees F. and fitted within the tubular member, a spindle engaged with the tubular member with its coupling nose fitted into the sleeve, an inner seat formed at an end with a concave recess adapted to receive the spherical surface of the spindle and at another end with a cylindrical opening coaxial with the concave recess and adapted to receive the cylindrical head of the spindle, an outer seat put over the inner seat and adapted to engage with a cylinder valve, and a plug fitted on the spindle, whereby the coupling device will automatically shut off the gas flow passage in the event that the temperature exceeds a safety standard.
