Abstract: This invention relates to a method and apparatus for measuring the phase change of an output optical signal from a device. In one embodiment an input optical signal is split into first and second optical signals, and the first optical signal is passed through the device while applying an external stimulus to the device, to produce an output optical signal having a phase shift. The carrier frequency of the second optical signal is changed, and the output optical signal and the changed second optical signal are then combined. The combined signal is detected in accordance with the external stimulus applied to the device, and the phase change of the output signal of the device is measured as a function of the external stimulus applied to the device.

Abstract: A blade or vane for a gas turbine engine includes a primary cooling system (42) with a series of medial passages (44, 46a, 46b, 46c, 48) and an auxiliary cooling system (92) with a series of cooling conduits (94). The conduits of the auxiliary cooling system are parallel to and radially coextensive with the medial passages and are disposed in the peripheral wall (16) of the airfoil between the medial passages and the airfoil external surface (28). The conduits are chordwisely situated in a zone of high heat load (104, 106) so that their effectiveness is optimized. The conduits may also be chordwisely coextensive with some of the medial passages so that coolant in the medial passages is protected from excessive temperature rise. The chordwise dimension C of the conduits is limited so that potentially damaging temperature gradients do not develop in the airfoil wall (16).

Abstract: In an automatic layout system each signal path is represented in a binary form by its connection points with top, right, bottom and left bus cells on an integrated circuit. A bit-by-bit comparator uses preset table data in a read-only memory to investigate each possible combination of the signal paths in order to select the signal paths that can share a common bus channel. A coordinate comparator uses another preset table data to check whether the selected signal path combination satisfy further conditions of channel sharing. If so, the signal path combination is treated as a single new signal path, which is again investigated to find further possible channel sharing. In a final list of signal paths supplied to a bus cell layout circuit, all of the signal paths that can share a common bus channel are represented as one signal path.

Abstract: A combined ski locking device and safety strap assembly that includes a riser strap affixed to the ski, a loop strap that is arranged to be closed about the skier's leg by any conventional fastener means, and a lock that cojoins the riser strap and the loop strap. In assembly, the loop strap is received in close sliding relationship within the lock and contains a pair of stop members that are spaced apart along its length to limit the extent of travel afforded the strap within the lock. A link is also secured to one end of the strap that can be united with the shackle of the lock. In practice, when used as a security device, the loop strap is first pulled to a fully extended position in the lock and the extended strap passed through the ski equipment and around a fixed object. The link is then clasped in the lock to secure the equipment.
