Patent number: 5414725Abstract: The present invention is directed to providing a passively mode-locked laser which can achieve higher-harmonic mode-locking to produce a pulse repetition rate comparable to that of known actively mode-locked lasers, without requiring the complex modulation schemes typically associated with active techniques. Exemplary embodiments of the present invention are directed to a passively mode-locked laser wherein mode-locking is achieved by harmonic partitioning of the laser cavity. In accordance with the present invention, relatively high repetition rates can be achieved to provide ultra-short pulses without requiring the complex modulation schemes of active techniques, and without becoming susceptible to instabilities typically associated with passive techniques wherein high repetition rates are achieved using subcavities.Type: GrantFiled: August 3, 1993Date of Patent: May 9, 1995Assignees: IMRA America, Inc., The Regents of the University of MichiganInventors: Martin E.

Patent number: 5412652Abstract: A method of managing a telecommunication subnetwork system composed of a number of network elements coupled together through an optical medium to form a Synchronous Optical NETwork (SONET) ring. Each of the network elements receives upon initiation or reconfiguration and then stores an identical ring table or knowledge database that is composed of data in a predetermined format and structure. The ring table defines the ring type and ring identification, number of nodes, ring status, node identification, sequence, and status, and provides ring provisioning tables and embedded SONET ring path identification/status information.

Patent number: 5411590Abstract: The present invention relates to improved injectors for use in CVD reactor systems, and more specifically for use in epitaxial deposition systems for processing a single wafer-at-a-time. The improved injectors of the present invention are used to provide a predetermined desired shaped velocity profile for the injected reactant gases for insuring a more uniform deposition on a single wafer to be processed within the reactor system. In the first embodiment, the reactant gas is fed into a horizontal gas distribution manifold cavity and distributed horizontally in both directions. The gas then passes through a manifold wall having a pattern of predetermined sized and spaced apertures therein. The size of the apertures and the distribution of these sizes, shapes the resultant velocity profile to a desired pattern.Type: GrantFiled: December 16, 1991Date of Patent: May 2, 1995Assignee: Advanced Semiconductor Materials America, Inc.Inventors: Mark R.

Patent number: 5412197Abstract: A bar code reader decodes a bar code symbol in a pixel image by transforming the data corresponding to the symbol along a first scan line, where the transformation comprises rotation and stretching. The reader generates a whitening gradient vector, a blackening gradient vector, and a count vector from the transformed data. The reader then transforms (by rotating and stretching) another set of data corresponding to the symbol along a second scan line. The reader updates the whitening and blackening gradient vectors and the count vector using the second set of transformed data. The reader then generates whitening and blackening gradient signals from the whitening and blackening gradient vectors and the count vector. The reader segments the whitening and blackening gradient signals and generates a single one-dimensional reconstructed signal based on the weighted centroids of the two segmented gradient signals. The reader then decodes the symbol by decoding the reconstructed signal.Type: GrantFiled: July 26, 1994Date of Patent: May 2, 1995Assignee: United Parcel Service of America, Inc.Inventor: Christopher E.

Patent number: 5410295Abstract: An anti-theft system for an automatic teller machine (ATM) causes a currency alarm pack to deface the currency supply in the event that an attempt is made to transport the entire ATM. When the machine is moved, a localized field is momentarily activated and thereafter deactivated and disabled for a first predetermined interval. A triggerable currency alarm in the money supply of the machine, includes a field detector and a motion detector. The currency alarm is triggered when the following three conditions concur. First, the field detector detects the localized field and thereafter ceases to detect the localized field. Second, the motion detector detects motion of the currency alarm during a predetermined delay interval less than the first predetermined interval during which the field is disabled. Third, the field detector does not reacquire the localized field during the predetermined delay interval.Type: GrantFiled: July 22, 1992Date of Patent: April 25, 1995Assignee: ICI Americas Inc.Inventor: Greg Van Lint
