Abstract: An integrated antenna-array-and-filter is provided that includes a plurality of resonators coupled to an input port of a dielectric waveguide network. At least one antenna couples to an output port of the dielectric waveguide network. The plurality of resonators is configured to provide a plurality of poles in a filter frequency response of the integrated antenna-array-and-filter. The dielectric waveguide network and the at least one antenna are configured to provide at least one final pole in the filter frequency response.

Abstract: An acoustic filter device includes an acoustic filter. The acoustic filter device also includes one or more structural layers forming one or more curved domes that define one or more cavities of the acoustic filter. The acoustic filter device further includes one or more integrated passive device (IPD) layers on the one or more structural layers.

Abstract: A filtenna using micro-acoustic resonators is provided. One example filtenna generally includes an antenna configured to have a first resonance frequency associated with electromagnetic oscillations of the antenna and one or more acoustic resonators coupled to the antenna, a first acoustic resonator in the one or more acoustic resonators configured to have a second resonance frequency associated with acoustic oscillations of the first acoustic resonator. The filtenna is configured to have a filter transfer function based at least in part on the first resonance frequency of the antenna and the second resonance frequency of the first acoustic resonator.

Abstract: A directional coupler, comprising a first high-frequency line for feeding a first high-frequency signal, a second high-frequency line for feeding a second high-frequency signal, and a coupling line for outputting signals from the first and the second high-frequency lines, wherein the coupling line comprises resistive segments, each comprising a predetermined impedance. Coupling properties and resistive damping and adapting properties can be integrated in the coupling line. A compact and low-cost construction of the directional coupler is thus made possible.

Abstract: Split IEEE 1394 bridges utilize individual portals or bundles of portals to communicate over a non-full-featured IEEE 1394 network such as a local or wide area network in combination with IEEE 1394 multi-portal bridges. Multi-portal bridges may be formed through the connection of several split bridges each with one or more IEEE 1394 portals over a core net. The core net is invisible to the IEEE 1394 nodes with respect to traffic originating from an IEEE 1394 bus for a destination in an IEEE 1394 bus, and the network elements allow for increased network scalability in both terms of physical size and levels of hierarchy. Useful properties of a core net such as availability of high-performance switches or increased reach are incorporated into an IEEE 1394 network.

Abstract: A multi-refillable spray can with a piston arranged in the cylindrical part of the interior of said can, whereby said piston has seals associated with the inner wall thereof. The area below the piston is filled with compressed air instead of the usual environmentally damaging propellant gases. The spray is accommodated in the area formed by the upper side of the piston, the lower side of the valve head and the upper inner wall of the can. The piston has a rubber valve on the upper side facing the spray, whereby the bottom of the can is fully closed.
