A method and apparatus for operating a gas turbine engine including determining a temperature of a working gas at a predetermined axial location within the engine. Acoustic signals are transmitted from a plurality of acoustic transmitters and are received at a plurality of acoustic receivers. Each acoustic signal defines a distinct line-of-sound path from one of the acoustic transmitters to an acoustic receiver corresponding to the line-of-sound path. A time-of-flight is determined for each of the signals traveling along the line-of-sound paths, and the time-of-flight for each of the signals is processed to determine a temperature in a region of the predetermined axial location.

A controllable watch winder for a self-winding mechanical watch, in which a turntable is provided to hold and rotate the watch, including a programmable microprocessor circuit configured to count the number of rotations executed by the turntable. In one aspect, the watch winder is configured to introduce, after the electronic circuit is activated, a delay period before the turntable commences rotating. In another aspect, the circuit may be configured to interrupt the rotation of the turntable with pauses, to break up the rotation into cyclical sets. The circuit may be configured to automatically predetermine the number of rotations in each set. In yet another aspect, the watch winder may be configured to be manually adjustable, to variably predetermine before use, the number of rotations to be executed by the turntable and the length of any pause between rotations.

A method for monitoring the operating conditions of an electric generator including the entire stator core and all winding components for conditions of mechanical strain and temperature throughout the machine by means of distributive fiber optic sensors based on both Rayleigh back scattering techniques and Brillouin frequency shift fiber optic sensor analysis both of which do not have the gaps and limitations associated with standard fiber Bragg grating fiber optic point sensors, by virtue of the fact that both Rayleigh and Brillouin scans and allow accurate strain and temperature determinations at all points along standard fiber optic cables of considerable length, approximately two kilometers in the case of the Brillouin, which effectively yields many tens of thousands of sensors throughout the entire standard fiber optic cable. Raman distributive temperature sensing also has a limited application. Single mode and polarizing maintaining fibers can both be analyzed and read with any Rayleigh or Brillouin distributive fiber optic sensor laser system allowing great flexibility in sensor spatial resolution, total sensed length, resolution and other factors not possible with conventional fiber Bragg gratings. A sealed fiber collection box located outside the electric generator permits enhanced reliability and reconfiguration into any number of desirable fiber layouts necessary for specific static and dynamic measurements in an optimal manner.

Systems and methods are presented that use light sensors and computing devices to compute the depth of an object using shuttered light pulses. In one embodiment, depth is determined as follows: A light emitter emits a pulse of light that is directed toward an object. The pulse is reflected off the object and travels toward a beam splitter. The beam splitter splits the reflected pulse into multiple pulses, with each pulse directed to a shuttered sensor with a different shutter location. The shuttered sensors measure the integrated intensity of the light, and these values are used to determine the depth of the object. A method is presented which calibrates a system that has an arbitrary number of shutters and enables the system to determine the depth of an object, even in the presence of ambient illumination and scattered light.

A method is disclosed for making an isochronous balance-wheel-and-spring assembly for a horological movement in which one spring out of a series of springs is paired with a balance wheel. The spring has characteristics that vary by comparison with other springs of the series, and the spring is designed to be mounted on the staff of the balance-wheel via a collet. One collet out of a set of collets of different sizes is selected on the basis of the spring's characteristics. The collets of different sizes have connection points for attachment of the spring that are located (after assembly) at different distances from the center of the balance staff, the choice of the collet of the most appropriate size facilitating the adjustment of the balance-wheel-and-spring assembly.

The present invention is directed to improving the accuracy with which a stationary array sensor provides cross directional measurements by providing an offset compensation to the stationary array sensor using the output of a scanning sensor associated with the manufacturing process. Exemplary embodiments correlate outputs from the stationary sensor array and the scanning array using a data reconciliation process. For example, a practical, real time data reconciliation of measurements from the scanning sensor and measurements from the stationary array sensor is achieved by computing offsets using a bank of Kalman filters to correlate outputs from the two sensors for each measurement zone, wherein each filter possesses a relatively simple computational structure. The Kalman filters can fuse the outputs from the stationary array sensor and the scanning sensor to track, and compensate, drift of the stationary array sensor.

Automatic watches use the movements of the wrist to re-wind the barrel spring and thus supply the necessary energy for the correct functioning of the watch. When the user cannot wear the watch it is proposed to place it on an automatic re-winding device. The device according to the invention is compact and modular. Furthermore, in order to avoid any error of manipulation, the starting and stopping of the re-winding device is done automatically by means of a detection of the presence of the watch (3). The passing of the strap in the detachable base (2) produces the tension of the device.

The grooves preferably extend across the horizontal dimension of the watchwinder to a point short of the front of the housing for concealment purposes, and are made relatively wide in relation to the dimensions of the housing to improve rigidity of an interlocked grouping of watchwinders and to simplify assembly. Preferably, the channels are of equal size and shape and spaced equidistantly apart. An array of interlocked watchwinders can be built up to varying size and shape, and one or more of the watchwinders can be selectively removed from anywhere within the array without disturbing the others.
