Abstract: A battery monitor and cycle status indicator is disclosed. The battery monitor includes a voltage sensor capable of sensing the voltage between two nodes, for example, the positive and negative terminals of a battery. The voltage sensor is connected to an analog-to-digital converter which converts the analog voltage level sensed by the voltage sensor to a digital form. In turn, the analog-to-digital converter is coupled to a microprocessor. The microprocessor determines battery state-of-charge and historical values that relate to battery condition based upon the voltage levels provided by the analog-to-digital converter. The microprocessor is also coupled to a memory which stores battery history values computed by the microprocessor and program instructions for operation of the microprocessor. The battery monitor also includes a display that is capable of displaying battery state-of-charge and the historical values determined by the microprocessor.

Abstract: A managed electrical outlet includes a plurality of electrical receptacles, a current sensor, logic circuitry, a switch driver, and one or more switches. The electrical current provided to the managed electrical outlet is measured by the current sensor, which in turn sends an electrical signal to the logic circuit, representative of the amount of electrical current flowing through the outlet. The logic circuit compares the level of current flowing through the outlet with a reference current level to determine whether an over-current state exists. If the logic circuit determines the presence of an over-current state, the logic circuit sends a signal to the switch driver, causing the switch driver to trigger the switch into an open-circuit condition. In a two-receptacle outlet, one of the two receptacles is coupled to the switch while the other receptacle is unmanaged.

Abstract: The housing may be quickly and easily assembled in a clam-shell manner. The housing includes a pair of half-shells with each having a tongue for connecting to a face plate and a locking mechanism for connecting the half-shells together. The tongues are inserted into a pair of tongue-receiving fulcrum structures of the plate so that the half-shells are positioned in an open clam-shell arrangement. To complete the connection and the formation of the housing, the half-shells are rotated towards each other until the locking mechanism of one of the half-shells fastens to the locking mechanism of the other half-shell. Furthermore, the housing provides a wall-mounting mechanism for releasably attaching the housing to a wall, wherein that mechanism has two operative positions, including locking and release positions. In the locking position, the wall-mounting mechanism securely mounts the housing to the wall, and in the release position, the housing is unmounted and removable from the wall.
