Abstract: A variable IC capacitor includes a semiconductor layer doped to contain mobile charge carriers. Capacitor electrodes C1 and C2 are disposed adjacent to each other on the layer's surface, gate electrodes G1 and G2 are disposed on opposite sides of C1 and C2, and source and sink electrodes are disposed on opposite sides of G1 and G2. Potentials are applied to the electrodes as needed to inject and then confine a finite charge into the region under C1 and C2. A drive voltage V applied between C1 and C2 causes the charge packet to move back and forth beneath them, such that the effective capacitance C seen by drive voltage V is given by C=Q/V, where Q is the magnitude of the charge packet.

Abstract: A method for fabricating an HBT is disclosed, wherein successive emitter, base, collector and sub-collector epitaxial layers are deposited on a substrate, with the substrate being adjacent to the sub-collector layer. The epitaxial layers are etched to provide locations for contact metals and emitter, base and contact metals are deposited on the emitter, base and sub-collector epitaxial layers, respectively. A self-alignment material is deposited on the surface of the substrate around the epitaxial layers and a planarization material is deposited on and covers the top surface of the HBT. The planarization material is then etched so it has a planar surface about the same level as the surface of the self-alignment material and the contact metals protrude from the planar surface. The planar metals are then deposited over the protruding portions of the contact metals.

Abstract: A trolley includes a front wheel assemblie (12) and a rear wheel assembly both assemblies mounted on a trolley frame. The front wheel assembly (12) includes a fixed wheel assembly (24) to aid control of the trolley. In one form the front wheel assembly (12) includes a pair of swivel castors (18) and a fixed wheel assembly (24) disposed between the castors (18). The front wheel assembly (12) is designed so that when the castors (18) swivel from their orientation for forward travel, the fixed wheel assembly (24) is caused to be lifted off the ground. The trolley also includes a camming device which is operative to lift the front wheel assembly (12) off the ground when the trolley is moved into a nested configuration with a like trolley.

Abstract: A waveguide is disclosed that shifts the phase of the signal passing through it. In one embodiment, the waveguide has an impedance structure on its walls that resonates at a frequency lower than the frequency of the signal passing through the waveguide. This causes the structure to present a capacitive impedance to the signal, increasing its propagation constant and shifting its phase. Another embodiment of the new waveguide has impedance structures on its wall that are voltage controlled to change the frequency at which the impedance structures resonate. The range of frequencies at which the structure can resonate is below the frequency of the signal passing through the waveguide. This allows the waveguide cause a adjust the shift in the phase of its signal. An amplifier array can be included in the waveguides to amplify the signal. A module can be constructed of the new waveguides and placed in the path of a millimeter beam.

Abstract: The present invention discloses a device and method for wireless communication between a paintball marker or gun and it's associated paintball loading device. This wireless communication, whether bidirectional or unidirectional, allows for the transmission of “load” commands and various other useful information between the paintball marker and the paintball feeding device. When the “load” command, which is much more responsive than the “passive” communication found in the prior art, is wirelessly received by the paintball feeding device, the paintball feeding device loads a singular or plurality of paintballs into the paintball marker of appropriate conduit.

Abstract: A precipitation gauge for measuring liquid and frozen precipitation is provided according to the present invention that includes a support structure having at least one light sensor, or pair of electrodes, and at least one light source disposed thereon so that the light sensor may receive light that is emitted from the light source. The light sensor or light sensors and the light source or light sources generally extend a substantial height of the support structure. The light sensor or light sensors generate an output signal in response to the amount of light received from the light source. A microprocessor receives the output signal or output signals from the light sensor or light sensors and determines whether precipitation is present between the light sensor or light sensors and the light source or light sources. Based on the output signal or output signals, the microprocessor determines and displays the level of precipitation. The microprocessor may also determine the density of frozen precipitation.

Abstract: A polymeric particulate material suitable for use in an ink-jet receiver is prepared by generating an emulsion comprising a first phase having a first carrier fluid and a second phase having a second carrier fluid, said first and second carrier fluids being immiscible; carrying out a first treatment to at least one component of the first phase to form and/or maintain a skeletal structure of the treated at least one component of the first phase; carrying out a second treatment to the second phase to substantially remove the carrier fluid thereby generating a large capacity porous structure defined by the skeletal structure; and mechanically dividing (e.g. milling) the skeletal structure. A coating of the particles is capable of rapid uptake of large quantities of ink, especially when formed using a high internal phase water-in-oil emulsion.
