Patent number: 5999546Abstract: In accordance with the invention, a tunable laser uses magnets to apply mechanical strain on fiber Bragg grating reflectors or laser cavities in order to induce a change in lasing wavelength. The strain can be tensile or compressive. The tunable laser comprises a laser cavity including a laser material for emitting light in response to stimulating light and two end reflectors one or more of which can be a Bragg grating. In preferred embodiments, latchable programmable magnets vary the grating periodicity and/or cavity length in a controlled, accurate manner so as to achieve desired tuning of the laser over a broad range of wavelengths. The latchable magnets hold the wavelength in the shifted position without the need for sustained power.Type: GrantFiled: September 22, 1998Date of Patent: December 7, 1999Assignee: Lucent Technologies Inc.Inventors: Rolando Patricio Espindola, Sungho Jin, Hareesh Mavoori

Patent number: 5999904Abstract: A processing system which acts as a participant in the collaborative dialogue is first trained using a training algorithm. The training algorithm computes, in conjunction with a current turn of the training dialogue, a task initiative index and a dialogue initiative index for a next turn of the dialogue, using cues observed during the current turn, probability assignments associated with the observed cues, and current values of the task initiative index and the dialogue initiative index. The algorithm then predicts a task initiative holder and a dialogue initiative holder for the next turn of the training dialogue, using the task initiative index and dialogue initiative index computed for the next turn. The probability assignments associated with the observed cues are adjusted if the predicted task and dialogue initiative holders do not agree with corresponding respective actual task and dialogue initiative holders for the next turn.Type: GrantFiled: July 2, 1997Date of Patent: December 7, 1999Assignee: Lucent Technologies Inc.Inventors: Michael Kenneth Brown, Jennifer Chu-Carroll

Patent number: 5999521Abstract: A system and method that controls a wireless call from a home system regardless of its current serving system. In this system, when a wireless telephone is roaming, the serving system sets up a transmission path to the home system. The home system performs all of the origination functions as if the wireless unit were in the local area and communicates via the transmission path, with the wireless unit using the serving system as an extension of the home system.Type: GrantFiled: June 6, 1997Date of Patent: December 7, 1999Assignee: Lucent Technologies Inc.Inventor: Robin Jeffrey Thompson

Patent number: 5999290Abstract: An add/drop multiplexer (ADM) 100 includes an optical demultiplexer 200 and an optical multiplexer 300 that are connected in series. The optical multiplexer and the optical demultiplexer each include a number of corresponding passbands, which means that the central wavelengths of the multiplexer's passbands are approximately equal to the central wavelengths of the demultiplexer's passbands. The performance of the ADM is improved by making the edges of corresponding passbands complementary to each other. In one illustrative design, the transmission of the demultiplexer decreases at its passband edges as the wavelength moves away from its central wavelength, whereas the transmission of the multiplexer increases as the wavelength moves away from its central wavelength. The resultant cascaded passband of the pair is wider than the passband of the demultiplexer alone, thereby increasing the number of ADMs in a chain for the same performance.Type: GrantFiled: October 27, 1997Date of Patent: December 7, 1999Assignee: Lucent Technologies Inc.Inventor: Yuan P. Li

Celsius. The inventive films are suitable for use in electromagnetic devices, e.g., in microtransformer cores, inductor cores and in magnetic read-write heads.Type: GrantFiled: March 2, 1998Date of Patent: December 7, 1999Assignee: Lucent Technologies Inc.Inventors: Sungho Jin, Timothy J.

Patent number: 5999963Abstract: A new scheduling method and policy for shared (server) resources, such as the CPU or disk memory of a multiprogrammed data processor. The scheduling is referred to as Move-To-Rear List Scheduling and it provides a cumulative service guarantee and well as more traditional guarantees such as fairness (proportional sharing) and bounded delay. In typical operation, a list is maintained for a server of processes seeking service from the server. Processes are admitted to the list only when maximum capacity constraints are not violated, and once on the list, are served in a front-to-back order. After receiving service, or upon the occurrence of other events, the position of the process on the list may be changed.Type: GrantFiled: November 7, 1997Date of Patent: December 7, 1999Assignee: Lucent Technologies, Inc.Inventors: John Louis Bruno, Eran Gabber, Banu Ozden, Abraham Silberschatz

Patent number: 5999052Abstract: An integrated circuit differential amplifier with a digitally controllable gain. In a preferred embodiment, the differential amplifier employs first and second transconductance (gm) amplifiers and a digital to analog converter (DAC). The first gm amplifier converts a differential input voltage into a differential output current and the second gm amplifier converts the differential output current into a differential output voltage. A digital input code is applied to the DAC to generate an analog output voltage that is applied to one of the gm amplifiers to control its transconductance to thereby control the gain of the differential amplifier. The second gm amplifier employs a pair of low impedance feedback paths between input/output terminals of opposite polarity. The gain of the differential amplifier is thus a function of the ratio of the transconductance of the first gm amplifier to that of the second gm amplifier.Type: GrantFiled: April 28, 1998Date of Patent: December 7, 1999Assignee: Lucent Technologies Inc.Inventor: Zhi-Long Tang

Patent number: 5994159Abstract: A self-assembling micron-sized mechanical device is described. The device comprises hinged plates attached to a support. A beam having a first end free to move in an upwardly-directed arc is associated with each hinged plate comprising the device. The beam has a first engagement member, including a first angled edge, disposed at its freely-movable first end. Each hinged plate includes a second engagement member, including a second angled edge. In the unassembled state, at least a portion of the first engagement member lies beneath the second engagement member on the support. Actuation force is applied to the beam by an actuator, the force causing the first end of the beam to lift. As it does so, the first and second angled edges slide over another, and the hinged plate is rotated upwardly about its hinges away from the support. The mechanical advantage provided by the angled edges allows a hinged plate to be rotated fully ninety degrees away from the support.Type: GrantFiled: December 22, 1997Date of Patent: November 30, 1999Assignee: Lucent Technologies, Inc.Inventors: Vladimir A. Aksyuk, David J. Bishop

Patent number: 5995676Abstract: Embodiments of the invention include a method and apparatus for determining values for data reproduced or retrieved from data storage media such as in holographic memory systems. The method includes initially approximating the value of data members retrieved initially from the data storage medium of interest (e.g., by their intensity levels based on an absolute scale), using those approximations collectively to establish one or more threshold levels for defining ranges for the data values to be determined, and determining values for the retrieved data members by comparing the initial data value approximations of the retrieved data members to the established threshold levels. Alternatively, the threshold level(s) are set initially and adjusted iteratively based on the initial approximations of the individual data members until a final established threshold level is established.Type: GrantFiled: December 26, 1996Date of Patent: November 30, 1999Assignee: Lucent Technologies Inc.Inventors: Scott Patrick Campbell, Kevin Richard Curtis, Thomas J.
