  • Patent number: 5933774
    Abstract: A location registering apparatus provides for redirecting of telephone calls intended for a mobile station to, for example, a land-line subscriber telephone number through the use of a station registering device and a suitably configured cellular recharger for charging a battery located in the mobile station. In operation, when a user places the mobile station in the cellular recharger, a signal from the cellular recharger and reflective of this action is provided to the station registering device. Upon receiving this signal, the station registering device initiates a call to a location register in the telephone network and reconfigures information for the mobile station in this network so that all calls intended for this mobile station are rerouted to the previously provided subscriber telephone number, for example, the station user's home or office number.

  • Patent number: 5933412
    Abstract: Parallel connection control ("PCC") processes and switching networks are described. Various aspects of these PCC processes and networks relate to the provision of an alternative switching connection setup to achieve bandwidth savings or lower cost networks with acceptable setup delay. The new approach provides an alternative to existing switch-by-switch sequential connection setup approaches. In the new approach, segments of the connection are set up by executing operations in parallel. The algorithm and network are also extended to address complex control connection tasks, such as the complex bearer control tasks of third-party connection control, unidirectional multicast connection setup, and multiparty-to-multiparty connection control.

  • Patent number: 5933336
    Abstract: A boost converter having multiple L-C branches and a method of operating the same. The boost converter includes first, second and third phase inputs and an output. In one embodiment, the boost converter includes first and second switches coupled between corresponding rails of the output. The boost converter also includes first, second and third capacitors that form first, second and third L-C series branches, respectively, with a first inductor. The first, second and third L-C series branches are coupled between the first, second and third phase inputs, respectively, and a node between the first and second switches. The first and second switches cooperate progressively to employ a voltage across the rails less a voltage across the first, second and third capacitors to discharge currents through the first inductor and thereby reduce input current total harmonic distortion (THD) on all three of the phase inputs.

  • Patent number: 5933376
    Abstract: An integrated circuit having a memory which includes an array of data storage cells is provided with a redundant array and a signal-directing circuit. A row or column signal for a defective cell, if present, as well as each successively higher row or column signal, is directed to sequentially higher address locations in the array to thereby avoid the defective cell address location. The last row or column signal is directed to the address location of the redundant array. A fuse is preferably associated with each row or column signal which may be selectively melted to direct the row or column signals. The array can be logically divided into subarrays each having an associated redundant array so that defects in each subarray can be accommodated.

  • Patent number: 5933836
    Abstract: A facility is provided for maintaining automatically the integrity of data associated with respective data applications. The facility achieves this result by providing a plurality of data modules for interfacing respective ones of the applications with their associated data bases such that, in response to receipt of a data request from one of the applications, the respective interfacing module unloads the requested data from the associated data base. The interfacing module then communicates with other ones of the modules to determine if the requested data is consistent with related data stored in their associated data bases. If the requested data is found to be so consistent, then the data is supplied to the requesting application. If not, then the interfacing module corrects the inconsistency in accord with predefined data rules, and then supplies the corrected data to the requesting data application.

  • Patent number: 5930425
    Abstract: A high density optical fiber coupling strip has two buildout members, each of which has a mating surface. Each mating surface has formed thereon a footprint that is identical for each member, so that the mating surface, when abutted together mesh with each other in proper alignment, thereby aligning the members, and can then be joined by welding or similar means. Regardless of the connector type to be received by each member, the footprints insures that the members will be properly mated, thus making possible hybrid coupling strips as well as unitary strips.

  • Patent number: 5930414
    Abstract: The effect of polarization mode dispersion that an optical signal experiences as it propagates through an optical transmission fiber is compensated for at a receiver using a birefringent compensator, in which the compensator automatically and adaptively generates a level of differential time delay that substantially equals the differential time delay that the optical signal experiences, but of different sign, and, therefore, essentially cancels out the undesired delay.

  • Patent number: 5930380
    Abstract: In a process of signature verification, an off-line test signature is compared to one or more on-line reference signatures. Dynamic data obtained from the reference signature or signatures may be used to improve the thinning of the test signature. Such data may also be used for segmenting the test signature and sequencing the resulting strokes. In some embodiments, the invention includes evaluating a dynamic error, based at least in part on such sequencing of the test signature. In some further embodiments, the invention includes producing a rendering of at least one on-line reference signature as a two-dimensional image, and evaluating a static error based, at least in part, on shape-matching between the rendered image and the test signature.

  • Patent number: 5930150
    Abstract: A computer system and method provide a CAD tool by which application specific optical integrated circuits may be easily and quickly designed. The computer system has a graphical user interface which provides the designer with an empty canvas upon which the user may place selected icons of any one of a plurality of optical devices. The designer can select from any one of a number of interconnects to place an icon of the selected interconnect between two of the optical devices. The characteristics of each optical device or interconnect may be varied from default settings to a desired group of settings. To verify the operation of a designed circuit, the user simply clicks each icon along an optical path and the computer system provides a spectral analysis of optical power versus wavelength for the defied optical path. The user can also design optical chips by selecting and placing end ports into an optical circuit and can then clump or group the entire optical circuit into a single icon representing the chip.

  • Patent number: 5927589
    Abstract: A fixture for use in the bonding of a plurality of chips each to a respective one of a plurality of substrates includes a lower vacuum chuck and a frame member supported on the chuck for reciprocatory motion toward and away from the chuck surface. The chuck surface is arranged to hold substrates with predeposited solder in pockets at predetermined locations thereon. The frame member has openings aligned with those pockets and weights which extend through the openings. After substrates are placed on the chuck surface, the substrates are heated so that the predeposited solder reaches eutectic status, and then chips are placed on the substrates. The frame member is then mounted on the chuck and gradually lowered until the weights press against respective chips, thereby holding the chips in position on the substrates. The entire assembly is then transported to a solder reflow bonding station.

  • Patent number: 5930751
    Abstract: A method for automatically confirming verbal commands issued by a user and received by an automatic speech recognition system. Each verbal command is associated with a command operator set in which one or more command operators are stored. After the user vocalizes a recognized verbal command, the automatic speech recognition system awaits vocalization of a valid command operator from an associated stored command operator set for a pre-determined period of time. During this waiting period a non-intrusive indicator such as a light or a low volume tone notifies the user that the automatic speech recognition system is awaiting or ready to receive an appropriate command operator. If the user vocalizes a valid and recognized command operator during the waiting period, then the automatic speech recognition system executes the verbal command using the command operator and issues a confirmation to the user that the verbal command has been executed.

  • Patent number: 5930587
    Abstract: A method for accurately and objectively evaluating stress migration effects on long term reliability of integrated circuits. A sample containing a conductive runner is fabricated according to a given fabrication process. The fabricated sample undergoes a heating step at a first temperature for a first time period to induce material interactions at an accelerated rate, followed by cooling the sample to a second temperature and maintaining the second temperature for a time of sufficient duration such that relaxation occurs. Then the sample undergoes a heating process at a third temperature for a time sufficient to nucleate a predetermined number of voids, followed by heating the sample runner at a fourth temperature, less than than the third temperature, to propagate the voids such that a maximum void size is determined. Void distribution is preferably monitored by optical and scanning electron microscopy.
