To provide a portable terminal, method or/and program that can reduce the energy consumption by automatically transmitting and receiving data based on the signal strength, rather than the user manually transitioning from sleep mode to active mode. The terminal processing means 18 commands the terminal to transition from the sleep mode to active mode based on the signal strength, and the data transmission and/or reception means 13 to perform data transfers..

Method and apparatus for controlling light levels to save energy
An occupancy sensor with integral light level sensors is configured to turn off or disable peripheral circuits and go into a periodic deep sleep mode to reduce phantom loading. Peripheral circuits include occupancy sensor circuits and relay drive circuits, but may include other circuits such as communication circuits.

Ultra low power apparatus and method to wake up a main processor
An apparatus and method for waking up a main processor (mp) in a low power or ultra-low power device preferably includes the mp, and a sub-processor (sp) that utilizes less power than the mp to monitor ambient conditions than the mp, and may be internalized in the mp. The mp and sp can remain in a sleep mode while an interrupt sensor monitors for changes in the ambient environment.

Sleep mode operation for networked end devices
A technique provides apparatuses, methods, and computer readable media for sending sleep information from an end device to a central unit of a network, in which the wake-up time of the end device is aligned to the scanning time for the central unit. The technique addresses at least two considerations: the clock accuracy of the end device is accounted for, and the reason that the end device requests sleep mode operation is provided.
