A portion of the capacitor material is then removed to form an interdigitated capacitor structure that incorporates a first contact and a second contact. Thereafter, a dielectric material is applied upon the interdigitated capacitor structure so that the structure is at least partially encapsulated by the substrate and the dielectric material. Capacitor structures also are provided.

Abstract: A thermal inkjet printer with firing nozzles perpendicular to the carriage motion has two motors: paper and carriage. These motors, alone or in concert, provide the power to the service station. The service station has separate wiping and pen cleaning functions. The wipers need to move across the pens in a direction that is perpendicular the carriage direction. Through the use of gears, the wipers can be made to clean the pens at the same time that the paper is being advanced and using the same motor source. For capping, the caps are moved into place as the pens come to rest. The motion of the pens themselves could easily push a lever that pushes the caps into place.

Abstract: A device for stabilizing the operating wavelength (&lgr;) of an electro-optical component having a nominal operating wavelength (&lgr;0) by means of a wavelength influencing circuit (4, 5) adapted to be driven by a control signal. The device comprises a semiconductor photodiode (3) adapted to be impinged upon by the radiation generated and/or processed by the component and to generate an output signal which is indicative of a difference of the wavelength of the radiation ((&lgr;) with respect to the nominal operating wavelength (&lgr;0, &lgr;i). The semiconductor photodiode (3) includes a plurality of layers jointly defining two opposite diodes generating opposite photocurrents as a result of radiation impinging onto the photodiode (3). The opposite photocurrents are adapted to generate the control signal to effect the stabilization action.

Abstract: Optical pulses at a given repetition rate (f) are obtained by modulating an optical signal (2) by means of a Mach-Zehnder modulator. The modulator (3) is driven by means of a driving signal including, in addition to a sinusoidal component at a frequency (f/2) half the repetition rate (f) of the pulses, at least one odd harmonic of the sinusoidal component. Very short optical pulses can thus be generated without giving rise to undesired side effects such as ringing in pulse tails.

Abstract: A system and method are described for providing remote demonstration and control of a test and measurement device. The system provides for user to request active instrument panel pages for a test and measurement device from a server. The server includes logic that emulates a test and measurement device instrument panel and provides constant update of the instrument panel page data regarding the remote control of the test and measurement device. The server in the correct message format provides the request for updated status data from a remote controlled instrument, for the selected remotely controlled test and measurement device. The server issues the received remote control requests to the remote controlled instrument. The remote controlled instrument provides data and reacts to commands received. The instrument, upon receiving a command or request for instrument state data, transmits said instrument state data to the server for further transmission to the client user interface for further display to a user.

Abstract: Two-dimensional photonic crystal slab apparatus and a method for fabricating two-dimensional photonic crystal slab apparatus. A two-dimensional photonic crystal slab apparatus has a photonic crystal slab containing a two-dimensional periodic lattice, and upper and lower cladding layers for the photonic crystal slab, the upper and lower cladding layers each having a metallic cladding layer. The metallic cladding layers permit achieving substantially perfect light transmission through a waveguide in the slab, even when the waveguide is strongly bent. The fabrication method includes forming a two-dimensional photonic crystal slab from a dielectric slab supported on a substrate by, for example, an etch process.

Abstract: The inventive interface mechanism generates an imitation MAC header and places the header before the data portion of the frame. The imitation header is formed from useful information which will enhance the troubleshooting process of analyzer software. The information would allow for upper layer protocol problems to be mapped down to lower layer ATM problems. The ATM destination address is encoded into the destination address of the imitation header. The port address upon which the data frame is captured is used as the source address of the imitation header. The inventive interface will allow the use of existing software which requires MAC headers to perform protocol analysis of routed ATM frames.

The value of the cross-sectional area at the boundary between the sub-channel and the main channel is less than the value of the cross-sectional area at the boundary between the sub-channel and the cavity. The gas permeates the cavity and the sub-channel and is capable of extending into the main channel.

Abstract: An optical switch includes a core, a fluid reservoir coupled to the core via a tube, a thermal solution, and an insulating structure. The core includes a base, a matrix controller substrate, and a planar lightwave circuit. The planar lightwave circuit has a plurality of waveguides and trenches for rerouting an optical stream. The fluid reservoir supplies fluid to the plurality of trenches of the core. The core and the fluid reservoir are mounted on the thermal solution, which maintains the fluid reservoir at a higher temperature than the core by removing heat from the core and transferring some heat to the fluid reservoir. The insulating structure reduces any thermal leakage from the fluid reservoir to the core. In addition, the insulating structure can improve the temperature of the planar lightwave circuit and prevent unwanted atmospheric gases from entering the optical switch.
