Abstract: A wave communication system includes an integrated circuit and a multilayered substrate. The multilayered substrate is electrically coupled to the integrated circuit. The multilayered substrate includes an antenna structure configured to transmit a circularly polarized wave in response to signals from the integrated circuit.

Abstract: An apparatus is provided. First and second hybrid couplers are provided with each having a first port, a second port, a third port, a fourth port and with each being substantially curvilinear. The fourth ports of the first and second hybrid couplers are first and second isolation port that are mutually coupled. The first port of the first hybrid coupler is configured to carry a first portion of a differential signal, and the first port of the second hybrid coupler is configured to carry a second portion of the differential signal.

Abstract: A system and method for providing travel assistance and travel event processing. Travel events may include, for example, a cancellation associated with a travel reservation, a delay associated with a travel reservation, a timing change associated with a travel reservation, a travel reservation transaction, an environmental change potentially affecting travel, a location tracking event, and a service offer. By way of example, a travel reservation may include a reservation for an airline, railway, bus company, watercraft company, hotel or other-types of room accommodations, business events, such as, for example, a seminar, a conference, and/or a dining reservation, and/or recreational events, such as, for example, a tour, a concert, a show, a sporting event, an exploration outing, dining reservations, and/or other type of reserved recreational event.

Abstract: A system comprises a communications network configured to support transmission of a plurality of communications streams and a resource manager communicatively coupled to the communications network and configured to provision resources of the communications network to the plurality of communications streams. The system may further comprise a performance test manager communicatively coupled to said communications network and configured to identify a communication stream from said plurality of communications streams, identify a test network path for said identified communication stream that is substantially free of other network traffic, and perform a performance test over said test network path.

Abstract: This invention pertains to gaseous analytes sensor devices comprising organic thin film transistor and, in particular, sensors able to perform the enantiomeric discrimination of gaseous analytes.
