摘要： A micro-optical delay element for a time-division multiplexing scheme is disclosed wherein two light beams are provided to a beam splitter/combiner (BS/C) in the absence of optical fibre. At least one beam exiting a modulator is collimated and reaches the (BS/C) unguided as a substantially collimated beam. This obviates a requirement for polarization controllers and polarization maintaining optical fiber

摘要： An apparatus for monitoring and controlling the wavelength of laser radiation includes at a least one optical filter for receiving laser radiation and for transmitting and reflecting first and second filtered beams, respectively. The beams are filtered according to respective first and second spectral filter functions that cross at at least one crossing wavelength. A beam comparison element compares the first and second filtered beams and produces an error signal representative of the deviation of the wavelength of the laser radiation from a set-point wavelength. Varying the angle of incidence of the laser radiation upon at least one optical filter varies the spectral filter function of that filter for selecting or varying the operating wavelength of the laser. A laser wavelength controller can receive the error signal for stabilizing or tuning the wavelength of the laser radiation.

摘要： Apparatus and methods for monitoring the wavelength of laser radiation and that provide a temperature-corrected error signal responsive to the deviation of the wavelength of the laser radiation from a nominal wavelength is disclosed. The apparatus includes a least one optical filter for filtering the laser radiation according to at least one spectral filter function to produce filtered laser radiation and at least one optical detector for detecting the filtered laser radiation to produce a first detected signal. The apparatus also includes a temperature sensor for sensing temperature characteristic of at least the optical filter and processing circuitry for providing a temperature-corrected output signal responsive to the deviation of the wavelength of the laser radiation from the nominal wavelength. The processing circuitry includes an error circuit for providing, responsive to at least the first detected signal, an uncorrected error signal responsive the deviation of the wavelength of the laser radiation from the nominal wavelength and a memory for providing offset values corresponding to selected temperatures. The processing circuitry, responsive to the temperature sensor, modifies the uncorrected signal based on at least one offset value to produce the temperature-corrected error signal. The laser wavelength monitoring apparatus can be advantageously combined with a laser and a laser wavelength control to provide a laser having a regulated or tunable wavelength.

The beams are filtered according to respective first and second spectral filter functions that cross at least one crossing wavelength. A beam comparing element compares the intensities of the first and second filtered beams and produces an error signal responsive to the deviation of the wavelength of the laser radiation from a set point wavelength. The beam comparing element can include first and second optical detectors and an error circuit for producing the error signal by taking a ratio or the difference of the signals detected by the detectors. Varying the angle of incidence of the laser radiation upon at least one optical filter varies the spectral filter function of that for selecting or varying the operating wavelength of the laser. A laser wavelength controller can receive the error signal for stabilizing or tuning the wavelength of the laser radiation. Several addition embodiments of the invention are disclosed.

摘要： A system and method for optimizing customizable filler cells in an integrated circuit physical design process. In particular, a filler cell placement algorithm of the present disclosure is utilized in the method to optimize the customizable filler cells in a circuit layout. The filler cell placement algorithm performs the operation of selecting a starting point within a given circuit layout, selecting a direction in which the position of logic cells is adjusted, adjusting the position of logic cells and, thereby, combining filler cells in order to increase the accumulated area thereof; suspending the adjustment operation when a customizable filler cell is formed; and resuming the adjustment operation from the point of the newly formed customizable filler cell. Additionally, a method of optimizing the locations, number, and distribution of the customizable filler cells in an integrated circuit design by use of the filler cell placement algorithm is provided.

摘要： Macro design techniques are disclosed for facilitating subsequent stage wiring across the macro. Whitespace areas within the macro are rearranged to accommodate the wiring. The rearrangement may take the form of physical rearrangement of the whitespace areas into routing tracks extending from one side of the macro to another; shielding using, for example, macro power bussing and/or macro wiring; routing power busses to the rearranged whitespace; and/or inserting active circuits with pins accessible to the wiring. In a preferred embodiment, active circuits are placed into rearranged macro whitespace during the design of subsequent stages. The rearrangement of the whitespace facilitates the wiring across the macro so that slew rate and path delay requirements of the subsequent stage wiring can be maintained, without excessive buffering or rerouting of wiring.

摘要： A method for improving the crosstalk and time-of-flight performance for signals in an integrated circuit with respect to the package-related wiring. I/O pads in the package-related wiring of a logic design meeting specified crosstalk and time-of-flight constraints are identified using a software tool. The tool produces a graphical display in which the identified I/O pads are highlighted. The tool enables a user to graphically manipulate the display to assign, i.e., establish an electrical connection, between I/O circuits corresponding to the signals and the highlighted I/O pads.

摘要： An integrated system and method to achieve ESD robustness on an integrated circuit (IC) in a fully automated ASIC design environment is described. Electrical characteristics and electrical limits on the power network are translated to power route region constraints for each chip input/output (I/O) cell. Electrical limits on the signal network are translated into signal route region constraints for each chip I/O cell. These constraints are passed on to an I/O floorplanner (automatic placer of I/O cells) that analyzes trade-offs between these constraints. For I/O cells that can not be placed to satisfy both power and signal region constraints, the I/O floorplanner utilizes the knowledge of alternative power distribution structures to group I/Os and create local power grid structures that have the effect of relaxing the power region constraints. Instructions for creating these local power grid structures are passed on to the automatic power routing tool.

摘要： An automated banking system, which comprises at least one remote transaction and cash dispensing unit interconnected with a central unit via a communication network is disclosed. Each remote unit is operable following a single customer card insertion, in either a first mode or a second mode, to process one or more transactions, including cash withdrawal, fund transfer and payment and deposit transactions. The central unit determines the mode of operation of each remote unit. In the first mode, the central unit communicates data to a remote unit following a request from the remote unit. The central unit may transmit information for updating the customer's card. The central unit communicates actual account balances which the remote unit reports to the customer. From other communicated data, which includes account descriptions, the remote unit determines which transactions a customer may perform. The remote unit then processes customer-selected transactions in accordance with additional communicated data, which includes working balances, an extended credit balance and a maximum cash limit. In the second mode, the remote unit does not communicate with the central unit, but itself both determines which transactions a customer may perform and processes customer-selected transactions in accordance with information included on the customer's card. In the first mode, the remote unit communicates customer transaction data to the central unit immediately after the customer completes his transactions. The remote unit, in the second mode, records customer transaction data which it communicates to the central unit when the remote unit becomes operable in the first mode. Line security and customer verification schemes are provided to protect the integrity of the system. Additional features are disclosed.
