Abstract: A dual battery electrical system for a vehicle having an engine comprises a primary load and a secondary load and is switchable between an ON state in which the engine is running, an OFF state in which the engine is not running, a START state in which the primary load requires power to start the engine, and a PAUSE state in which the engine is not running. A first battery powers the primary load, a second battery powers the secondary load, a battery switch is closable to connect the first battery to the second battery such that both batteries can provide power to both loads. The transition to and from the OFF state is via a user activated mechanism and transition to and from the PAUSE state is via a user-independent mechanism. A controller controls operation of the battery switch when the system enters and/or leaves the PAUSE state.

Abstract: In accordance with various aspects of the present invention, a method and circuit for reducing power consumption of a power strip is provided. In an exemplary embodiment, a power strip is configured for reducing or eliminating power during idle mode by disengaging an outlet from power input. A power strip may include two or more outlets and two or more outlet circuits, with AC power input connected to the outlets through the outlet circuit(s), which may include a current transformer, a control circuit, and a switch. The current transformer secondary winding provides an output power level signal proportional to the outlet load. If behavior of the current transformer secondary winding indicates that the outlet is drawing substantially no power from the AC power input, the switch facilitates disengaging of the current transformer primary from the outlet.

Abstract: In an emulated computing environment, a method is provided for allocating resources of the host computer system among multiple virtual machines resident on the host computer system. On the basis of the proportional weight of each virtual machine, a proportional share of resources is allocated for each virtual machine. If, for a particular virtual machine, the calculated share is less than a reserved minimum share, the virtual machine is allocated its reserved minimum share as its share of processor resources. An emulation program modulates the access of each virtual machine to the resources of the host computer system.

Abstract: A linearly actuated switch assembly is adjustably disposed in a housing stem bore of a robotic crash protector device. An actuation plate is disposed over the central bore of the contact surface. As the piston moves toward the housing base in response to a crash force or torque applied to the actuator, the actuation plate moves in an axial direction, and contacts and actuates the switch. The actuation plate is biased towards the contact surface by an actuation spring disposed between the actuation plate and a spring plate that is rigidly affixed to the housing stem. This arrangement allows the actuation plate to “float” with respect to the fixed spring plate. In particular, the actuation plate may assume the orientation of the piston, which may be canted from its default orientation—normal to the device central axis—by uneven application of force by the actuator.

Abstract: In accordance with various aspects of the present invention, a method and circuit for reducing power consumption of a wall plate system during idle conditions is provided. In an exemplary embodiment, a wall plate system is configured for reducing power during idle mode by disengaging at least one outlet from a power input. A wall plate system may include one or more outlets and one or more wall plate circuits, with power input connected to the outlets through the wall plate circuit(s). The wall plate circuit may include a current measuring system, a control circuit, and a switch. The current measuring system provides, through the switch, an output power signal that is proportional to the load at the outlet. If behavior of the current measuring system indicates that an outlet is drawing substantially no power from the power input, the switch disengages the power input from the outlet.

Abstract: An interface system prevents operational interference between a vehicle power door and a ramp of an access system by interrupting power to the motors and actuators responsible for operating the door. The interface system includes a relay system that does not interrupt, read, signal, or otherwise interfere with the communication lines between a body control unit, door control unit, or remote control transmitter or receiver. Thus, the interface system functions without the need to receive and transmit signals on the vehicle's communication bus. The interface system enables the ramp controller of the access system to be a separate module, which controls the ramp and kneel functions, because the only input the ramp controller provides to the power door system is to a ground signal that mimics that of a switch included in the vehicle.
