Patent EP-0556951-A1 (EP)
Inventor: ZIRNGIBL MARTIN
IPC: H01S3/13
Filed: 1993-01-20
Abstract: This invention relates to an optical limiting amplifier which provides an optical output signal of substantially constant power for an optical input signal of varying power which is simple to construct and economical to build. In this invention, an optical signal whose power can fluctuate over a wide range is split into two signals. The first signal is applied to an optical fiber amplifier (84) in the forward feed direction. The second signal is passed through a saturable absorber (86) and then applied to the optical fiber amplifier in the backward feed direction. The signal from the saturable absorber varies at a rate which is greater than the rate at which the signal to the saturable absorber varies. Thus, as the signal to the saturable absorber increases, the signal from the saturable absorber will increase at a greater rate; and, as the signal to the saturable absorber decreases, the signal from the saturable absorber will decrease at a greater rate. The backward feed signal affects the gain saturation of the optical fiber amplifier in such a way as to cause the output power of the optical fiber amplifier to be constant regardless of variations to the input signal power.

Abstract: A speed or torque probe (10) comprises a permanent magnet (14) having its north-south axis extending radially of a bladed rotor, so that the tips of the blades (24) pass in close proximity to one pole of the magnet (14), and a T-shaped pole piece (12,16,18). A first portion (12) of the pole piece, corresponding to the upright portion of its T-shape, extends tangentially of the rotor, with its free end in contact with the other pole of the magnet (14), while the other portion (16,18) of the pole piece, corresponding to the cross-piece of its T-shape, again extends radially of the rotor. As a result, the magnet (14), the first portion of the pole piece and the half (16) of the other portion nearer to the rotor form a variable magnetic circuit, such that the passing rotor blades (24) induce eddy currents in a first coil (20) wound upon the half of the other portion of the pole piece nearer to the rotor. A second coil (22) is wound on the half (18) of the other portion of the pole piece further from the rotor, and connected in opposition to the first coil (20), so that voltages induced by stray external magnetic fields in the first coil (20) tend to be cancelled by those induced by these same fields in the second coil (22).

Abstract: A detection system and method for determining the phase relationship between a crankshaft and one or more independently phase shiftable camshafts (12,14) which the system integrates into camshaft and cylinder identification sensors (58,60) for determining both cam location for variable cam phasing, and for generating a cylinder identification signal uniquely identifying one of the cylinders, for sequential fuel injection, thus reducing: (i) the number of sensors needed to operate the system to a single crankshaft sensor and a single sensor for each camshaft; and (ii) the number of high-speed inputs needed on the on-board engine control unit microprocessor. The number of sensing teeth on the independent cam wheels (62,72) vary depending upon the number of cylinders and the number of independently phase shiftable camshafts in the engine. Each sensing tooth is associated with one of the engine's cylinders and one cam wheel (72) contains an extra cylinder identification tooth associated with a selected cylinder.

Abstract: A chopper-stabilized switched-capacitor filter (bk5) has a discrete-time sequence (bk16); and a discrete-time multiplier (bk6) connected to the dicrete-time sequence. The discrete-time multiplier receives an input signal (X), and multiplies it by the discrete-time sequence to produce a chopped input signal. A discrete-time filter (bk7) is connected to the discrete-time multiplier to receive and filter the chopped input signal, and produces a filtered output signal. The discrete-time filter may be a discrete-time high-pass or low-pass filter depending upon the desired function, e.g. low-pass or bandpass filtering function, of the chopper-stabilized switched-capacitor filter.

Abstract: The improved valve of the present invention is a self-contained emergency safety shutdown valve which does not require the attendance of an individual or an outside power source for its emergency shutdown. The valve illustrated is a gate valve with the gate movable between positions opening and closing flow through the valve and having a stem (24) which is controlled by a ball shaft (56) extending through a rotary ball nut (58) with means for preventing rotation of ball nut in one direction and means urging stem, gate and ball shaft in a direction closing flow through the valve. The control means (90) controlling the release of the rotation preventing means is controlled by both high and low pressure responsive devices which are interconnected to a plunger for operating the release and to a plunger for sensing the pressure downstream of the valve. At any time the sensed pressure is beyond either the low or high pressure set points, the plunger is moved to operate the release and the gate is returned by the urging means to its closed position. A means is provided by which the release means it held in the release position until manually released but is easily manually release so that the gate may be opening while the control means is ineffective to cause shutdown until normal flow conditions are established.
