Abstract: This invention relates to a roofing panel for interconnection with one or more additional roofing panels. The roofing panel comprises a PV cell coupled to an inverter, and wireless (or optionally wired) power transfer circuitry for transmitting power to another roofing panel and/or the AC grid and/or to an AC inverter, and/or for receiving power from another roofing panel.

Abstract: A device comprising a storage array, the storage array comprising a first signal line and a second signal line, at least one correlated electron switch in electrical communication with the first signal line and the second signal line, and control circuitry for driving the correlated electron switch with at least one programming signal.

Abstract: A sleep monitor system includes a sensor unit, a processing unit and a mobile interface. The sensor unit is arranged to detect a number of variables corresponding to sleep status of a subject. The processing unit is programmed to receive data derived from the number of variables and process the data to produce user output. The mobile interface is arranged to present user output to one or more users.

Abstract: A method and system for monitoring sleep of a subject is disclosed. In one aspect, the sleep of the subject is monitored using a sensor unit including infrared array sensors for sleep tracking, which is used to track motion and also to detect presence of the subject. Further, the environment surrounding the subject is monitored. Subsequently, sleep data and environment data is generated and stored on a memory of the sensor unit. The present disclosure makes recommendations to the carer to improve the sleep quality of the child based upon the sleep data and environmental data via a portable interaction device such as a mobile phone.

Abstract: A processor employs a set of replica paths at a processor to determine an operating frequency and voltage for the processor. The replica paths each represent one or more circuit paths at a functional module of the processor. The delays at the replica paths are normalized to increase the likelihood that the replica paths accurately represent the behavior of the circuit paths of the functional module. After normalization, a distribution of delay values is generated by varying, at each replica path, the delay at an output node of the replica path until a mismatch is detected between a signal at the output node of the replica path and the delayed representation of the signal. The resulting distribution of delay values can then be adjusted based on variations in reference voltages at the replica paths to account for potential distribution errors resulting from the reference voltage variations.
