Abstract: Apparatuses, systems, and methods are disclosed that incorporate Bragg gratings. Optical components and systems of the present invention include Bragg gratings produced by selectively hydrogenating one or more selected sections of an optical waveguide in general, and particularly optical fiber. Selective hydrogenation can be performed by selectively establishing local conditions in a first environment conducive to introducing greater quantities of hydrogen into selected sections than into non-selected sections, which are maintained in a second environment. The extent of selective hydrogenation and the hydrogen concentration difference between selected and non-selected section of the waveguide is a function of the temperature, pressure, and time of exposure established in the first and second environments.

Abstract: Method for closed-loop control of a steam turbine with a steam bleed, a closed-loop control device for a steam turbine with a steam bleed, and a steam turbine with a steam bleed The invention relates to a method for closed-loop control of a steam turbine (1) with a steam bleed (21, 23) for various operational tasks (BA, BB, BC), which are each characterized by the nature of the controlled variables (R1, R2) used for closed-loop control. Actuating signals (S1, S2, S3) for actuating elements (43, 45) for valves (15, 17, 19, 25, 27) are derived, using a closed-loop control structure (37), from closed-loop control signals (YE, YS) of the regulators (33, 35) which are used. Only a single closed-loop control structure (37) is used for all the operational tasks (BA, BB, BC), as a result of which the design of the closed-loop control is simplified, the closed-loop control signals (YE, YS) are decoupled, and a smooth changeover is achieved between the operational tasks (BA, BB, BC).

Granted: 2006-08-01
Abstract: A reduced keyboard disambiguating system. The keyboard has twelve to sixteen keys, nine of them labeled with numerous letters and other symbols, and those nine plus one more are associated each with one of the ten digits. Textual entry keystrokes are ambiguous. The user strikes a delimiting "Select" key, or a key with an unambiguous character interpretation, at the end of each word, delimiting a keystroke sequence that could match any of a plurality of words associated with the same keystroke sequence. Each input keystroke sequence is processed with a complete vocabulary, and words which match the sequence of keystrokes are presented to the user in order of decreasing frequency of use. The vocabulary is stored in a special format that supports significant data compression without requiring additional processing. In addition, stems of longer words whose initial letters match the sequence of keystrokes are also presented to the user in order of decreasing frequency of use. If the frequency of the words associated with a stem is high enough, that stem is displayed as the default word object. Activations of an ambiguous key associated with a plurality of punctuation characters are disambiguated from the context of the surrounding keystrokes.

Abstract: Système optique de condensation et de regroupement comprenant un premier réflecteur et un deuxième réflecteur. Ce premier et ce deuxième réflecteur comprennent une partie d'un ellipsoïde de révolution possédant deux foyers et un axe optique. Une source de rayonnement électromagnétique est placée au niveau de l'un des foyers du premier réflecteur afin de produire un rayonnement convergent vers le deuxième foyer du premier réflecteur. Les deuxièmes foyers des réflecteurs coïncident. Le deuxième réflecteur est placé de manière à recevoir le rayonnement après son passage à travers un deuxième foyer du deuxième réflecteur et concentre le rayonnement en direction d'une cible placée au niveau du premier foyer du deuxième réflecteur. Dans le but d'obtenir un éclairage maximum de la cible, le premier et le deuxième réflecteur présentent pratiquement la même dimension et la même forme et sont positionnés en symétrie optique l'un par rapport à l'autre, de sorte que le rayonnement réfléchi par une partie de surface du premier réflecteur ellipsoïdal est ensuite réfléchi par une partie de surface correspondante du deuxième réflecteur ellipsoïdal afin d'atteindre une amplification unitaire entre la source et son image focalisée. Ces réflecteurs ellipsoïdaux peuvent comprendre des parties non ellipsoïdales ou peuvent être éventuellement remplacés par des réflecteurs sphériques ou toroïdaux.

Granted: 2009-06-23
Abstract: A single piezoelectric (22) is excited at a first frequency to cause two vibration modes in a resonator (24) producing a first elliptical motion (100a) in a first direction at a selected contacting portion (44) of the resonator that is placed in frictional engagement with a driven element (42) to move the driven element in a first direction. A second frequency excites the same piezoelectric (22) to cause two vibration modes of the resonator producing a second preferably elliptical motion (100b) in a second direction the selected contacting portion (44) to move the drive element (42) in a second direction. The piezoelectric is preloaded in compression by the resonator. Walls of the resonator are stressed past their yield point to maintain the preload. Specially shaped ends on the piezoelectric help preloading. The piezoelectric can send or receive vibratory signals through the driven element to or from sensors to determine the position of the driven element relative to the piezoelectric element or resonator. Conversely, the piezoelectric element can receive vibration or electrical signals passed through the driven element to determine the position of the driven element. The resonator is resiliently urged against the driven elemen t, or vice versa. Plural resonators can drive common driven elements.

Granted: 2008-11-25
Abstract: An interface circuit replaces a selected IDE command received from a host computer with an invalid command and routes the invalid command to a data storage device. In this manner, the interface circuit provides convenient, cost-effective technique for preventing a selected IDE command sent by the host computer from reaching the data storage device. Moreover, by replacing the selected command with an invalid command, rather than merely blocking th e selected command, the data storage device can respond with an error message rather than leaving the data storage device and the IDE bus in a non- deterministic state that might require user intervention. The interface circuit is particularly well-suited for preventing a host computer from writing to an IDE hard disk drive in a gaming machine.

Granted: 2010-01-05
Abstract: A perforation gun (10) is secured to the inside bore of a well completion tu be (30) by a releasable connection module (20). The connection module mechanism includes radially expanding anchor dogs (46) that are retained at an expande d position by a latching mechanism that may be released, alternatively, by combustion gas or by wireline. When the perforation gun (10) is discharged, gas from the discharge combustion displaces a retaining piston (54). Displacement of the retaining piston (54) releases a latch pin (56) and allo ws the gun weight to shift a secondary release sleeve (40). Shift of the secondary release sleeve (40) releases a latch dog retention pin (38) and hence, releases the anchor dogs (46) from a meshed connection with the completion tube (30). The secondary release sleeve (40) may also be shifted by the upward pull of a wireline.

Abstract: Video encoding and decoding processes provide compression and decompression of digitized video signals representing display motion in video sequences of multiple image frames. The encoder process utilizes object- or feature-based video compression to improve the accuracy and versatility of encoding interframe motion and interframe image features. Video information is compressed relative to objects or features of arbitrary configurations, rather than fixed, regular arrays of pixels as in conventional video compression methods. This reduces the error components and thereby improves the compression efficiency and accuracy. The decoder process decompresses the encoded video information to reconstruct the objects or features of arbitrary configurations.
