Abstract: An integrated wireless-global positioning system determines the location of a wireless terminal from satellite measurements and wireless network measurements. The accuracy of the location identified is dependent upon the quality of the measurement from the wireless network which, unfortunately, can contain measurement errors such as biases. Biases are caused by time delays which occur during the processing and transmission of signals. The time delays vary for each sector/base station and for each type of wireless terminal model being used. Calibration of these biases is important for the success of the integrated wireless global positioning system. For a small network system which has only a handful of base stations/wireless terminals, a specific system to calibrate the time delays for each base station and/or wireless terminal can be set up. The approach is, however, costly, time consuming, and subject to many errors.

Abstract: In a system in which the modulation scheme employed may change on a per-time-slot basis, a user's available data rate may change even if the user maintains the same number of time slots, because the capacity of the user's time slots may change. If one or more such changes in modulation scheme occurs, the data rate available to the user may no longer match his current data rate needs. Therefore, a method is disclosed for determining the number of time slots to assign to a user as a function of the user's current data rate requirement and the actual current cumulative data rate of the time slots currently assigned to the user. The user data rate requirement may further be a function of a quality of service (QoS) contracted for by the user.

Abstract: There is disclosed a method of processing a signal which comprises sampling the signal at a sampling frequency. Discrete time components at the sampling interval are thereby generated. Inverting alternate ones of the discrete time components thereby translates a frequency component of the sampled signal in one part of the Nyquist band to another part of the Nyquist band. The step of inverting alternate ones of the discrete time components is shown to comprise multiplying the sampled signal by a reference signal at half the sampling frequency and having discrete time components at the sampling interval. Circuitry for implementing the method is also disclosed.

Abstract: In a network where frequency synchronous lower bit rate signals are combined to form a high bit rate signal by using hierarchies of multiplexers, i.e., concatenated multiplexers of different bit rate levels, an apparatus is provided for adjusting the phase deviations that occur between data input signals and a common clock signal. In one embodiment, the apparatus includes delay lines for delaying the input signals of the multiplexers of the lower hierarchies.

Abstract: Vulnerability of an optical network to channel impairments or the like, is addressed by utilizing real-time monitoring and control of prescribed optical channel impairments. The impairments are compensated for by employing an optimization process in the optical network such that the optical signals from the source or sources of the impairments are controllably adjusted at any particular node in the network. The optical signals are attenuated more or less at the source node of the associated optical channel in order to optimize performance of the corresponding optical channel in the network. A variable optical attenuator (VOA) is used at the &lgr; laser source of optical channel having the impairment to obtain the attenuation. The optical signal impairment is measured at a receiving node and the source node of the associated optical channel is determined.

Abstract: A class of superconductive materials containing copper-oxygen bonding and with mixed cation-occupancy designed with a view to size and valence consideration yield useful values of critical temperature and other properties. Uses entail all applications which involves superconducting materials such as magnets and transmission lines which require continuous superconductivity paths as well as detectors (e.g., which may rely on tunneling).

Abstract: An application program interface capable of routing commands received from external devices to the appropriate system application that is runtime configurable is disclosed. At runtime, the application program interface receives enrollment signals from external interface packages used to provide communications to the external devices and dynamically updates a first routing table. Additionally, at runtime, the application program interface receives enrollment signals from system application packages used to perform system commands and dynamically updates a second routing table. The routing tables are used to route command request and responses between the external interface and system application packages and thus, provides a communication interface between external devices and system application software. Since the routing tables are configured at runtime, the application program interface can be re-configured without re-compiling the software used to implement it.

A plurality of flexible members are proximate each aperture. For each aperture, the plurality of flexible members are configured to maintain a centering bias on a connector when such connector is supported in the respective aperture.

Abstract: A method of authenticating electronic data is disclosed. In the preferred embodiment, when a Receiver makes a request to a Signer (e.g., a bank customer asks the bank to issue E-Coin), the Receiver includes a “hint generation value” in the request, and from the hint generation value, a “hint value” is derived and recorded on a signing transcript. The hint generation value is essentially an encrypted version of the request submitted from the Receiver to the Signer. When a merchant/Verifier transmits deposit signatures corresponding to spent E-Coin to be deposited, the transmitted signature is decrypted and blinded by the Signer in the same manner as that used to create the hint value. Thus, the encrypted incoming deposit signature from the merchant/Verifier should match the hint value stored on the signing transcript, confirming that the E-Coin is valid without revealing any identifying information about who spent the E-Coin, i.e., anonymity is preserved.

Abstract: A free space multiport wavelength router for directing channels of a received WDM optic signal to a plurality of output ports. The inventive router includes a lens which receives an incoming WDM signal and focuses the signal on a grating for angular displacement, as a function of wavelength, of the individual channels in the WDM signal. The angularly displaced channels are then collimated by the lens and provided to an array of optical elements. The array is oriented relative to the lens so that each element in the array receives and imparts an orthogonal displacement to a corresponding channel relative to the dispersement direction provided by the grating. The othogonally-dispersed channels are then reflected back to the grating and are output to select output optic fibers.

Abstract: A method and apparatus are disclosed for selectively passing or blocking an optical signal using an opaque or reflective shutter that is selectively positioned in or out of the light path. The disclosed wavelength blocker can be employed to filter input wavelength-division multiplexed (WDM) signal comprised of N wavelength channels, where a mechanical shutter array selectively passes each of the N wavelength channels. Each mechanical shutter may be controlled, for example, by a micromachine control element that physically lifts the shutter into or out of the lightpath. The disclosed wavelength blockers may be utilized in wavelength-selective cross connects, as well as other optical devices. In an exemplary wavelength-selective cross connect, an array of mirrors are employed in a planar waveguide having two sets of waveguide gratings intersecting at an angle.

Abstract: A method and system that broadcasts different messages into different geographic areas based on the appropriateness, desirability or necessity of broadcasting each messages to each area is disclosed. In particular, the illustrative embodiment of the present invention is a wireless telecommunications system that uses a portion of its spare bandwidth to broadcast messages to the receivers within its domain. The content of the messages can represent advertising, public service announcements, weather and stock reports, etc. One aspect of the illustrative embodiment is that the domain serviced by it is partitioned into a plurality of tessellated areas called “geographic regions.” From a single broadcast server, the various messages to be broadcast are broadcast not to the entire domain of the system, but to only those geographic regions within the domain where the content of those messages is appropriate, necessary or desirable.

Abstract: A method and apparatus for applying an electrical signal as a first of two inputs to a logic element, manipulating the output of the logic element such that the logic element produces a resulting electrical signal that logically transitions only when the input signal has associated with it a predetermined logic state, shaping the resulting electrical signal according to a desired RZ optical signal, amplifying the shaped electrical signal such that a maximum and a minimum signal level of the shaped electrical signal correspond to the adjacent optical power transfer zeroes of an optical modulator, and applying the amplified electrical signal as a driver input to the optical modulator.

Abstract: An orthodontic appliance audio receiver injects sound into the head and ear cavities of the wearer using vibration, e.g., mandibular (or skull) vibration. Using mandibular vibration, the wearer hears the audio source noiselessly, effortlessly, and without disturbing others, yet provides themselves with entertainment or other audio information. The orthodontia metalwork may be used to form an antenna. Hearing audio (e.g., music) by ‘feeling’ vibrations from the orthodontic appliance audio receiver encourages a patient to wear their prescribed orthodontia, improving and/or expediting the overall orthodontic therapy. A wireless (or even wired in low cost applications) audio signal receiver is built-in to a retainer, together with a transducer and a power source such as a battery, allowing unlimited transfer of information directly into the wearer's head through their mouth.

Abstract: A plurality of switching modules (102) are interconnected via an optical link (104) to form a switching system (100). Different wavelengths of the optical link (104) are used to selectively direct communications between the plurality of switching modules. Wavelengths have a fixed or variable allocation to communications between switching modules. Wavelengths may be time multiplexed or further subdivided by fractional wavelengths. Communications between switching modules are accomplished by allocating wavelengths in the optical link to transmitting and selectively receiving the communications on the allocated wavelengths.

Abstract: A method and apparatus for establishing a suppressed ringing connection between a server and customer premises equipment, wherein the server is connected to a first switch and the customer premises equipment is connected to a second switch, different from said first switch. The switch connected to the server has translation information identifying the trunk to the server as a server trunk. Signaling between the server, which is not connected to the Common Channel Signaling Network (CCS7), and the second switch is performed according to the protocols used for sending messages to a switch connected to the target customer premises equipment that is at the other end of the suppressed ringing connection. The first switch converts signals received from the server into a common channel signaling format for transmission to the second switch, serving the target CPE. The second switch then establishes a suppressed ringing connection to the target CPE.
