Abstract: Embodiments of the disclosure relate to redundant controllers to improve design robustness in voltage regulation modules. Aspects include detecting, by a control switch, a failure of a first controller of a first circuit, the first circuit controlling power output from at least one phase. Aspects include initiating, by the control switch, a second controller of a second circuit to retrieve an image for operating the at least one phase. Aspects include receiving, from the second controller, a control signal having commands for operating the at least one phase based on the image.

Abstract: A device may include an AC input. A device may include a DC output. A device may include power blocks. A device may include a controlling chip configured to detect a fault in one of the power blocks and isolate the power block with the fault while allowing power to flow through other power blocks.

Abstract: A semiconductor device with at least one embedded photodetector is disclosed. The at least one photodetector is embedded in a hot carrier injection (HCI) area, and detects a quantity of emitted photons. Further, the photodetector triggers a warning when the photodetector detects a number of photons greater than a threshold number of photons. Additional embodiments are directed to a method of detecting HCI. The method includes embedding a photodetector in a power semiconductor device, setting at least one threshold number of photons, detecting photons, determining a number of photons, determining when the number of photons is above a threshold number of photons, and generating a warning. When the number of photons is above the threshold, the warning is triggered. Further embodiments are directed to an article of manufacture comprising at least one semiconductor device with at least one photodetector embedded in an area predicted to experience HCI.

Abstract: Embodiments generally relate to devices, systems and methods for separating CTCs from blood cells using optical trapping, such as use of optical cogwheel tweezers. Through a pre-filtration process, using optical cogwheel tweezers, desired cells from a cell sample can be filtered from a relatively dilute sample. The filtered sample can then be analyzed by more precise means to determine overall concentrations from the original sample while maintaining cell viability.
