Abstract: A method of energy distribution from a plurality of energy sources to a plurality of loads wherein a set of selection options for a load are determined. Values are established for the selection options for each loads. The loads are then ordered into a load order according to a load ordering parameter. The energy sources are ordered in a plurality of sequences, where each sequence corresponds to a possible set of values for the selection options and wherein at least one energy source appears in more than one of the plurality of sequences. The loads are then matched with the energy sources according to the load order, with the sources in the sequence corresponding to the set of values for the selection options established for that load. A computing system designed to perform this method, and an electrical grid incorporating such a computing system are also described.

Abstract: A peak detector comprises multiple small-size amplitude detection circuits coupled in parallel to signal inputs at which a signal is received from a VCO. Each amplitude detection circuit generates a voltage on an output, indicating a voltage peak or amplitude of a first signal input and a second signal input (specifically, differential output of VCO). At a given time, only one small-size amplitude detection circuit is activated to load VCO, reducing the impact on LC resonant frequency. The plurality of small-size detection circuits work sequentially, and an automatic averaging of their outputs can significantly improve the peak detector fluctuation (caused by process variation and device mismatch) compared to each single small-size amplitude detection circuit.

Abstract: Methods and devices for reading and programming a state of a switch device are presented. Reading of the state is provided by measuring a resistance of the switch via injection of a current. If a measured resistance does not correspond to a resistance of an expected state, then the switch is reprogrammed, and the state reread. The switch device may form part of a complex switch circuit that includes a combination of shunt and through switch devices. Currents injected into external loads coupled to the switch circuit increase accuracy in reading of the state. Further accuracy in reading of the state of a through switch device is provided by provision of a bypass path to a shunt switch device. The complex switch circuit may be implemented as a SPDT switch including two branches, each branch including a shunt and a through switch device. Several types of switch devices, such as phase-change material (PCM) devices may be implemented.
