Abstract:
Described herein are representative embodiments of amplifier bypass paths and amplifiers using such bypass paths. In certain exemplary embodiments, the amplifiers are operated as linear power amplifiers, such as may be used in wireless communications systems. According to one exemplary embodiment, an amplifier circuit is described comprising an amplifier path coupled between a first node and a second node. The amplifier path comprises one or more amplifiers. The circuit further comprises a bypass path coupled between the first node and the second node. The bypass path comprises two impedance inverting networks and a ground path that is selectively coupled to the bypass path at a third node located between the two impedance inverting networks. In this embodiment, the third node is configured to remain coupled to the two impedance inverting networks when the ground path is coupled to the bypass path.

Each pixel comprises at least one layer of organic light emitting material 46, and an (at least semi-) transparent electrode 48 in contact with the organic layer on a side thereof remote from the substrate, the electrode comprising an electrically conducting polymer 50.
Abstract:
A method for presenting data comprises receiving the data; and deriving a multi-level dynamic hierarchical structure for the data based on drilldown sequences input from a user, wherein the drilldown sequences automatically compute a graphical visual comparison of the data and comprise: deriving a multi-pixel bar chart to display an aggregated data paradigm; and deriving a graphical illustration to display a data distribution paradigm.
Abstract:
A surface acoustic wave device including a thin layer of piezoelectric material, a layer of molecular bonder, and a carrier substrate. The thin layer constitutes an acoustic energy guide that augments the performance characteristics of the device. A method for making the acoustic wave device includes a step of molecular bonding between a carrier substrate and a piezoelectric substrate, and then a step for reducing the thickness of the piezoelectric substrate.
Abstract:
The present invention discloses a gas burner for a solid fuel effect gas fire. The burner comprises an integrally formed metal casing defining a gas/air mix chamber. A gas/air mix supply pipe connects with the chamber and a number of burner bores are provided in a wall of the casing. Simulated solid fuel elements can then be located above or on the said wall of the casing so as to not close said burner bores. Age will not affect the performance of the burner as can happen in prior art burners where the casing is formed by an open trough closed by a ceramic plaque where gas/air mix bores extend through the ceramic plaque which is moulded with a number of simulated fuel elements on its upper surface, and sealed by mastic or filler to the rim of the trough which mastic deteriorates with age.
