Abstract: A packet energy transfer (PET) receiver comprising receiver front-end circuitry including an input, an output, and at least one switch connected at the output. There is receiver output control and conditioning circuity including an input and an output to be connected to an electrical load. There is a synchronizer circuit to close the switch to allow power to flow into the receiver output control and conditioning circuitry during each of the first plurality of transfer periods of the transmitter and to open the switch to prevent power to flow into the receiver output circuitry during a first plurality of sample periods. There is a load controller that disables the synchronizer circuit and operates the switch to close it and allow power to flow into the receiver output control and conditioning circuitry during subsequent transfer periods and to open the switch to prevent power to flow during a subsequent sample periods.

Abstract: A multi-drop, packet energy transfer (PET) receiver configured to be electrically connected to a PET transmission line and an electric load comprising receiver front-end circuitry including an input configured to be electrically connected to the PET transmission line, an output; and at least one switch or at least one diode connected at the output. There is a receiver output control and conditioning circuity with an input connected to the switch/diode, an output to be connected to the electrical load. There is a bootstrap capacitor connected across the input, and a bulk capacitor connected across the output and across the electric load. There is a load controller configured to operate the switch/diode to allow power to flow into the receiver output control and conditioning circuitry during transfer periods and to prevent power to flow into the receiver output circuitry during sample periods.

Abstract: A PET transmitter including an input conditioning and protection circuitry electrically connected to an electrical source, having an output and a switch connected at the output. There is a front end circuit having an input connected to the switch and an output connected to a PET transmission line. There is a source controller configured to close the switch to connect the source to the output of the front end circuit during a transfer period and open the switch to disconnect the source during a sample period. Across the output of the front end circuit, there is a minimum effective cross-line capacitance that enables the source controller to differentiate a measured voltage at the output of the front end circuit indicative of a fault and a measured voltage indicative of no fault without a PET receiver being in electrical communication with the output of the front end circuit.

Abstract: The invention relates to a pathogen testing system that can analyses multiple samples at once in order to provide guidance on the presence of an infection in a given environment. This reduces the number of individual tests that are needed and provides enhanced confidence as to the levels of pathogen in a given environment.

Abstract: A system for preparing and analyzing a sample of biological material, including a test cartridge having a first housing defining a flow-through chamber, a second housing defining a central space within which the first housing is at least partially located. The first housing is rotatable relative to the second housing, and the second housing defines a plurality of circumferentially spaced chambers, one of the chambers having an inlet for receiving a sample, at least one of the chambers containing a liquid reagent, and at least one of the chambers comprising an analysis module, the chambers of the second housing each having an opening into the central space. The first housing has one or more openings into the central space so that openings can be selectively aligned with one of the openings into the chambers of the second housing by relative rotation of the first housing and second housings.
