Abstract: Methods and systems for an integrated sensor network are described. In one embodiment, sensor data may be accessed from a plurality of motion sensors and a bed sensor deployed in a living unit for a first time period. An activity pattern for the first time period may be identified based on at least a portion of sensor data associated with the first time period. The activity pattern may represent a physical and cognitive health condition of a person residing in the living unit. Additional sensor data may be accessed from the motion sensors and the bed sensor deployed for a second time period. A determination of whether a deviation of the activity pattern of the first time period has occurred for the second time period may be performed. An alert may be generated based on a determination that the derivation has occurred. In some embodiments, user feedback is captured on the significance of the alerts, and the alert method is customized based on this feedback. Additional methods and systems are disclosed.

Abstract: An apparatus is provided for modifying a timing signal generated by a timing signal generator. The timing signal is modified indirectly by first modifying a power supply signal from a power supply upon which the timing signal generator is dependent to generate the timing signal. Initiating an introduction of at least one transient signal component of variable length by a transient insertion device into the power supply signal causes the timing signal generator to be disrupted and at least one transient signal component to be introduced within the timing signal. A particular implementation of the invention is an electrical circuit consisting of both active and passive electronic components.
