    Abstract: An apparatus includes an inverter including a high-side switch coupled to a low-side switch, the inverter generating a time-varying drive current from a plurality of drive control signals, a positive rail voltage, and a negative rail voltage wherein controlling the switches to generate the time-varying drive current produces a potential transitory overshoot condition for one of the switches of the inverter; a drive control, coupled to the inverter, to generate the drive control signals and to set a level of each of the rail voltages responsive to a plurality of controller signals; and a controller monitoring one or more parameters indicative of the potential transitory voltage overshoot condition, the controller dynamically adjusting, responsive to the monitored parameters, the controller signals to reduce a risk of occurrence of the potential transitory voltage overshoot condition.

    Abstract: The invention relates, in various aspects, to systems and methods for linking content stored on a computer network with content broadcast over a television network. The system includes a database, a trigger mechanism, a communications interface, and a packet generator. The database stores tokens representative of links to the stored content and delivery information representative of at least a duration for delivering the token. The trigger mechanism indicates an instruction to deliver a token over the television network, generating a signal indicating a respective one of the stored tokens and a time for starting the delivery of the respective token. The communications interface has a channel in communication with a television set box device for transferring the respective token to the television set box device. The packet generator generates packets within a stream of television content to be broadcast over the television network.

    Abstract: The present invention provides a macromolecular switch (51) suitable for use in a data acquisition and/or processing device. The switch comprises a macromolecular structure (10) having an ion binding site (14), and is flippable between a plurality of discretely different conformations corresponding to different ion binding conditions at the ion binding site (14). The macromolecular structure (10) is provided with at least one electrochemical input device (43) for applying such different ion binding conditions to the ion binding site (14) in response to corresponding external input signals. The invention also provides a method for data acquisition and/or processing, using a macromolecular structure switch of the invention.

    Abstract: A surface acoustic wave sensor or identification device has a piezoelectric material, and an interdigitated transducer (IDT) input/output mounted on the piezoelectric material for receiving a radio frequency (RF) signal and propagating a corresponding surface acoustic wave along a surface of the piezoelectric material. An IDT finger electrode array is mounted on the piezoelectric material and is operable to communicate with the IDT input/output for transmission of a modified RF signal from the device. The IDT finger electrode array has at least one finger electrode segment whose propagating characteristics are controlled to control the nature of the modified RF signal. A biolayer is mounted on the piezoelectric material and is associated with the finger electrode segment, and a fluidic chamber is associated with the biolayer. In use, the fluidic chamber contains fluid which, if a predetermined substance to be sensed or detected is present, operates to modify the biolayer which in turn controls the nature of the modified RF signal.
