Abstract: Systems and methods are described for profiling the power consumption of software instructions executing on a processor. A power measurement circuit records power consumption levels of a processor executing various software instructions. A profiling tool tracks and identifies the instructions being executed on the processor and generates an association between the instructions and the power consumed during execution of those instructions. The power profile enables the precise isolation and identification of instructions relative to amounts of power consumed during the execution of those instructions.

Abstract: An electronic monitoring system particularly useful as a telephone babysitter comprises a monitoring unit connectable to the telephone line at the location to be monitored, and a portable sound-producing unit for actuating the monitoring unit from a remote telephone handset via the telephone line. The monitoring unit at the monitored location includes a microphone, a code detector detecting a predetermined code transmitted by the portable sound-producing unit, a keyboard for storing the telephone number of a selected remote telephone handset, a sound level comparator, automatic dialling means, and a microcomputer including a plurality of settable flags controlling the monitoring unit according to preprogrammed routines and in response to the transmission of preselected codes by the portable sound-producing unit.
