Abstract: Capacitively isolated current-loaded or current-driven charge pump circuits and related methods transfer electrical energy from a primary side to a secondary side over a capacitive isolation boundary, using a controlled current source to charge isolation capacitors with constant current, as opposed to current impulses, while maintaining output voltage within tolerance.

The devices and methods transfer electrical energy over an isolated capacitive barrier in a manner that is efficient, inexpensive, and reduces electromagnetic interference (EMI).

Abstract: Technologies transmit scheduling in multi-radio devices are described. One multi-radio device includes first and second radios and a scheduler circuit. The scheduler circuit outputs a first signal to the radios in a first mode in which the first radio is transmitting first data and the second WLAN radio is transmitting second data concurrently. The first signal increases a first clear channel assessment energy detect (CCA-ED) threshold to a second CCA-ED threshold. The scheduler circuit outputs a second signal to the second WLAN radio in a second mode. The second signal causes transmission of fourth data to be delayed until after the first radio completes reception of third data. In a third mode, the scheduler circuit outputs a third signal to the first WLAN radio. The third signal causes transmission of fifth data to be delayed until after the second radio completes reception of sixth data.

The processor processes the first frame as a mesh frame using first processing logic and processes the second frame as an AP frame using second processing logic.

Abstract: A universal bacterial assay and kit for detecting and monitoring changes in concentration of a target analyte in solution. The assay relies on an engineered high affinity protein-based sensor with a detectable label that has high specificity to a target analyte, typically a ligand or metallated complex, and can be used to spectroscopically monitor interaction of the target analyte with a test bacterial strain. The sensors can be in the form of living, transport-deficient bacterial cells expressing the engineered high affinity protein, or in the form of purified proteins themselves. The system can further be used to screen candidate compounds for interference with the binding and uptake of such analytes by bacterial cells, which is useful in investigation of new classes of antibiotics.
