Abstract: Apparatus and a method for controlling of a telecommunications station. A controlling computer establishes a data connection to a controlled computer. The controlled computer is connected via a data connection to the station. The controlled computer receives status information from the station and forwards this information to the controlling computer. The controlling computer, responsive to receipt of user commands, send status control commands to the controlled computer which sends status control commands to the station. Advantageously, if a connection can be established between the controlling and controlled computers, the controlling computer, responsive to user commands, can control the status of the station.

Abstract: An electromechanical phase shifter for a microstrip microwave transmission line includes a conductive base plate and a pair of microstrip transmission line segments supported parallel to each other and parallel to and spaced from the base plate. A movable microstrip transmission line bridges the pair of transmission line segments and is movable therealong to provide a short circuit therebetween. A movable ground element is coupled to the bridging transmission line for movement therewith and is in contact with the pair of transmission line segments and the base plate. The spacing between the movable bridging transmission line and the ground element is maintained at one quarter wavelength of the center frequency of the signal frequency band.

Abstract: A method and an electronic data processing apparatus for wave synthesis that retains the true qualities of naturally occurring sounds, such as those of musical instruments, speech, or other sounds. Transfer functions representative of recorded sound samples are pre-calculated and stored for use in an interpolative process to generate a transfer function representative of the sound to be synthesized. The preferred transfer functions are Chebyshev polynomial-based transfer functions, which assure a highly predictable harmonic content of synthesized sound. Output sound generation is driven by time domain signals produced by reconversion of a sequence of interpolated transfer functions. Non-harmonic sounds are synthesized using multiple frequency inputs to the reconverting (waveshaping) stage, or by parallel waveshaping stages. Speech sibilants and noise envelopes of instruments are synthesized by the input of noise into the waveshaping stage by modulation of a sinusoid with band-limited noise.

Abstract: An integrated circuit has an output buffer circuit for driving voltage state transitions of a transmission line. An output transistor has a gate terminal for controlling an output voltage of the output transistor, which is applied at an output terminal to the transmission line. (A voltage state transition comprises changing the output voltage from a first state voltage to a second state voltage.) An impulse current driver injects charge into the gate terminal during an impulse phase at the beginning of the voltage state transition to rapidly bring the output transistor through its dead zone to the threshold of its active region. A slewing current driver provides a comparatively limited current to the gate terminal after the impulse phase to cause the output transistor to complete a substantially smooth voltage state transition.

Abstract: An automatic channel responsive television input source selection switch couples output signals from a selected one of a plurality of input television input source interface circuits to a television in accordance with a user channel selected with a user channel selector manually controlled through one of a remote control unit and interface and a manual interface. A look-up table memory stores each of the possible user channel numbers along with an associated input signal source channel and an indication of signal source identity, such as indication of a direct broadcast satellite television signal source, a public television broadcast source and a security camera source. The switch based on the associations stored in the look-up memory selects the associated video input signal source and provides an indication of the associated source channel number to a tuner included in the selected interface.

Abstract: A network interface circuit employs an extended feedback circuit topology for impedance matching across a high voltage boundary between a line side portion and low voltage portion of a network. The network interface circuit includes an operational amplifier-based circuit which is responsive to a signal applied from user equipment on the low voltage portion. Specifically, the present invention includes a transmit path having a first, second, and third amplifier circuit and an impedance element, and a receive path that includes a transfer function implemented as a second order low pass filter for correcting amplifier gain and phase effects in the complex feedback loop of the circuit. The output impedance is remotely set by multiplying the impedance element by a scale factor to match the network impedance. The feedback loop is extended across the high voltage boundary using high voltage interfaces such as linear optical coupling devices (LOCs).

Abstract: A method of making a capacitor includes the steps of forming an interconnection line above a substrate, depositing a first dielectric layer on the interconnection line, and etching a via in the first dielectric layer. The via has a tapered width which increases in a direction toward the substrate. Further, the method includes filling the via with a conductive metal to form a metal plug, and etching a trench in the first dielectric layer around an upper portion of the metal plug. The metal plug has a tapered width which secures it into the dielectric layer. A second dielectric layer is deposited adjacent the metal plug and an upper electrode is deposited on the second dielectric layer. Preferably, a lower electrode is deposited to line the trench and contact the metal plug.

Abstract: An alternate access platform is coupled to the Internet, a local-exchange-carrier (LEC), and other communications facilities such as a plurality of long-distance facilities provided by any one of a number of long distance carriers. Access to the alternate access platform occurs in any one of a number of ways. For example, a user, or calling party, establishes an Internet connection to the alternate access platform, or dials into the alternate access platform via a local plain-old-telephone-service (POTS) call. Independent of the access method, the alternate access platform selects a communications facility for routing the call as a function of a “call profile” associated with the calling party. This “call profile” uses any one of a number of parameters to determine routing such as called party, cost, quality, reliability, time-of-day, etc. This “call profile” is either determined by the user on a call-by-call basis, or is separately administered by the user.

Abstract: A WDM add/drop device for use in an optic communications system for adding and dropping optical wavelengths from a multiple-wavelength optical system. The device includes a set of lenses, a planar grating wavelength multiplexer and a micromirror array switchable for individual wavelengths of the multiple-wavelength signal between a transmit mode and a reflect mode. The grating angularly demultiplexes a multiple-wavelength optical signal in a first direction and the individual wavelengths are processed by the micromirror array and directed to the grating in a second direction. The micromirror array will either reflect select wavelengths to a first port or transmit select wavelengths to a second port. In a preferred embodiment, ports on a first multiport circulator input the multiple-wavelength optical signal to the WDM add/drop device and output the multiple-wavelength optical signal from the WDM add/drop device.

Abstract: Aligned Optoelectronic assembly with improved dimensional stability is disclosed. The assembly is carried out with a bonding material, either a solder or an adhesive, which contain insoluble, non-coarsening dispersoid particles. New solder compositions having enhanced mechanical properties are described. Relatively inert particles having a diameter of 5000 nm or less are dispersed in a solder material having an average grain size of approximately 10,000 nm or less to produce such solder compositions. The dispersed particles act as physical barriers in solders substantially impeding the motion of grain boundaries and inhibiting grain growth during thermal and stress cycling which substantially inhibits coarsening. As a consequence, the optoelectronic device assembly according to the invention exhibit substantially improved dimensional stability, with the rate of creep deformation at the joint reduced by a factor of at least two.

Abstract: A general rate N/(N+1) (0, G), code construction, e.g., for a magnetic recording system, allows for encoding or decoding of a dataword having N elements, N preferably being an integer multiple of eight. The dataword is divided into N/8 bytes of binary data that are encoded as a run-length limited (RLL) codeword in accordance with the general rate N/(N+1) (0, G) code construction. The general rate N/(N+1) (0, G) code construction is characterized by the constraints (d=0, G=(N/4)+1, l=N/8, r=N/8). the N/(N+1) (0 (N/4)+1, N/8, N/8) RLL codeword is constructed from the dataword in accordance with 1) pivot bits identifying code violations related to the constraints, 2) correction bits set to correct code violations, and 3) preserved elements having values not included in the code violations.

Abstract: A tool for removing an EMI/RFI shield assembly cover. The tool includes two body members arranged for reciprocating movement toward and away from each other over a limited distance. Each body member has a gripper member extending outwardly therefrom which, when the body members are spaced apart, slide over opposed sides of the shield cover. When the body members are subsequently moved together, the gripper members engage edges of the opposed sides of the cover so that subsequent movement of the tool removes the cover from the base.
