Abstract: A CPE such as an ISDN telephone subset or multimedia equipment includes an interface recognition unit that connects to the network interface and adapts itself to allow the CPE to be used with standard ISDN interfaces and an analog interface. The interface recognition unit includes an interface recognition switch (IRS) that performs two functions. First, the IRS protects the CPE from damage in those instances where a non-standard network interface is connected to the CPE. Second, for standard interfaces, it identifies the type of network interface and routes the incoming signals appropriately. Specifically, if the IRS detects a T interface, the incoming signals are switched directly to a T interface circuit for controlling and powering the higher functions of the CPE. If the IRS detects a U interface, incoming signals are automatically switched to a U interface circuit for controlling and powering the CPE.

Abstract: A packetized cellular system in which a mobile quasi-periodically transmits a beacon signal containing an ID number to a first base station in the cell in which it is located for storage with the ID's of other active mobiles in the cell. A copy of a list of the active mobiles in that cell is transmitted to all adjacent cells where they are placed on non-active list. Control of a mobile is handed-off to a second base station upon the receipt of a transmitted ID number of the mobile at the second base station. The mobile is then listed as active in the database of the second base station and non-active in the first base station.

Abstract: Individuals are provided with a transaction card which is to be presented for at least certain classes of transactions, e.g., truck rentals, purchases of chemicals, etc. Encoded electronically within the card are a) physical verification information and b) identity information. The identity information is encrypted, to create an encrypted identity file, using an "identity encryption key." The matching "identity decryption key" is held in secret by an appropriate government agency or agencies. The encrypted identity file and the physical verification information are then commingled and encrypted together using the "public encryption key" of a so-called public key encryption/decryption pair to create a composite encrypted file. The matching "public decryption key" is distributed to the society at large and is, in particular, stored at points-of-sale/transaction.

Abstract: A method for maintaining the performance of the system while identifying and reclaiming unreferenced tuples. A set of status bits is associated with each tuple, which are used to indicate the current state of the tuple, and whether it is in a transient state while the garbage collector, according to this invention, is examining it, thus permitting the garbage collector to run without locking out other processing. Further, the garbage collector uses the status bits to audit linked lists used by a database manager against linkage failure. Finally, the garbage collector compresses data and removes redundant data found while traversing the tuple structure of the database.

Abstract: A method and apparatus for granting to a telephone customer the same features that he has at home when he is away from home. The customer, while being served from a remote switching system, is connected to the home switching system. After the customer is duly authorized, the block of data defining the features allocated to the customer is associated with the call control process for serving the customer from the remote switch. Advantageously, using such as arrangement, calls made by the customer from the remote switch may be billed to the account of the home customer and all features that are available to the home customer are made available for use by the customer when served by the remote switch.

Abstract: The invention relates to a fixed gap waveguide taper. The waveguide taper has a first end and a second end for being coupled to a fiber. The waveguide taper includes a plurality of segments extending from the first end toward the second end. The segments include a gap portion and a core portion. In the present invention, the gap portion remains fixed at a constant length s throughout the entire waveguide taper. In contrast, the core section of the segment varies from the waveguide end of the taper toward the fiber end of the taper. In particular, the core section in each of the segments progressively decreases in length from the waveguide end toward the fiber end of the taper. Accordingly, the length of the segment .LAMBDA. progressively decreases from the waveguide end toward the fiber end of the taper.

Abstract: A multi-frequency optical signal source is adapted to include a plurality of power splitters, each connected to obtain a portion of an electrical data signal used to modulate a different one of the plurality of input optical sources; a plurality of delay means, each connected to an output of a different power splitter, each delay means providing a different predetermined signal delay; and an electrical signal combiner having a plurality of inputs, each input connected to a different output of the respective delay means, for electrically combining a portion of the modulation signal received from the connected delay means to form a combined electrical signal at an output of the electrical signal combiner, the output of the combiner being connected to control biasing of the optical output amplifier. The resulting multi-frequency optical signal source exhibits reduced signal distortion and crosstalk by keeping the carrier density constant in its shared optical output amplifier.

The depth of the depressions are precisely determined by the thickness of the layer applied to the substrate. By contacting the mold with resin in a fluid state, a component is fabricated having microfeatures formed monolithically thereon.

Abstract: A method for making a metal-to-metal capacitor for an integrated circuit includes forming a layer of titanium/titanium nitride on a polysilicon which has been patterned with interlevel dielectrics. A capacitor dielectric is then deposited, followed by patterning with photoresist to delineate the capacitor, etching to remove extraneous dielectric, deposition of aluminum, further patterning and etching to define the capacitor and access area, and removal of photoresist.

Abstract: Application programs compiled for a first, "source", computer are translated, from their object form, for execution on a section, "target", computer. The translated application programs are linked or otherwise bound with a translation of the source computer system software. The translated system software operates on the image of the source computer address space in the target computer exactly as it did in the source computer. The semantics of the source computer system softwae are thus preserved identically. In addition, a virtual hardware environment is provided in the target computer to manage events and to deal with differences in the address space layouts between the source and target computers.

Abstract: The single-polysilicon active pixel comprises a photo site located on a substrate for generating and storing charge carriers, the charge carriers being generated from photonic energy incident upon the photo site and semiconductor substrate, a photo gate, a transfer transistor and output and reset electronics. The gate of the transfer transistor and the photo gate are defined in a single layer of polysilicon disposed on the semiconductor substrate. The source of transfer transistor is a doped region of substrate, referred to as a coupling diffusion, which provides the electrical coupling between the photo gate and the transfer transistor. The coupling diffusion allows for the transfer of a signal stored in a photo site under the photo gate to the output electronics for processing. The single-polysilicon active pixel may be operated by biasing the transfer transistor to the low operating voltage of the pixel, for example, 0 volts.

Abstract: A passive optical network is provided that spectrally slices optical signals transmitted in both upstream and downstream directions utilizing wavelength division multiplexing routing. The passive optical network preferably includes an incoherent signal source at both ends to provide signals that are spectrally sliced according to optical frequency. The downstream information may be transmitted in a conventional data format. The upstream transmissions may be segregated by subcarrier multiplexing, time scheduling or wavelength division multiplexing.
