摘要： A valve assembly includes a valve body, a valve element, a valve actuator, and a fluid-operated switch. The valve body defines a flow passage. The valve element is disposed at least partially within the flow passage and is moveable between an open position and a closed position. The valve actuator is coupled to the valve element and is responsive to pressurized fluid supplied thereto and vented therefrom to move the valve element between the open position and the closed position, respectively. The fluid-operated switch has a first fluid inlet, a second fluid inlet, a third fluid inlet, an actuator port, and an actuator vent port. The fluid-operated switch is in fluid communication with the valve actuator and is operable to selectively supply pressurized fluid to the actuator via the actuator port, and vent the pressurized fluid from the actuator via the actuator port and the actuator vent port.

摘要： A system for detecting liquid flow from a nozzle in a semiconductor processing device includes a first fiber optic sensor, a second fiber optic sensor, and an amp. The first fiber optic sensor and second fiber optic sensor are located on opposite sides of at least one nozzle. The first fiber optic sensor transmits light, and the second fiber optic sensor receives more of the light when the nozzle is not dispensing liquid than when the nozzle is dispensing liquid. The amp is coupled to the first fiber optic sensor and second fiber optic sensor. The amp indicates whether the nozzle is dispensing liquid according to an amount of the light received at the second fiber optic sensor.

摘要： A power tool external power supply assembly for reducing weight and increasing run time of a power tool includes a backpack positionable upon a user. A battery, which is rechargeable, is positioned in the backpack. A power cord is operationally engaged to and extends from the battery through a hole in the backpack. A connector engaged to the power cord distal from the battery can be engaged to a direct current powered device, such as a power tool, so that the battery is operationally engaged thereto. The battery can power the direct current powered device without the user having to support a mass of the battery in a hand along with the direct current powered device.

摘要： A method and apparatus for decoding forward error correction (FEC) encoded data. A stream of units of FEC encoded bits are received, where the units are derived from a transmitted signal, where each unit represents a one-bit data value, and where each unit includes correctness bits that together reflect a level of probability that the one-bit data value represented by the unit differs from corresponding bits in the signal before it was transmitted. The stream of units of FEC encoded bits are decoded by using the quality level of bits to perform soft-decision convolution decoding on the stream of units of FEC bits, where the soft-decision convolution decoding produces, for block decoding, a stream of symbols made up of bits. In the stream of units of FEC bits, subsequences of units that are prone to erroneous soft-decision convolution decoding are detected by determining, for the sub-sequences whether the distribution of quality bits indicate the units are below a threshold level of correctness, and by comparing characteristics of that distribution to a given set of characteristics predetermined to be prone to result in incorrect decoding. Among the symbols produced for block decoding, symbols containing one or more bits that correspond to units that were in subsequences detected to be prone to erroneous soft-decision convolution decoding are flagged or tagged, and thereby, errors in the stream of symbols may be soft-decision block decoded by erasing the flagged symbols.
