Abstract:
Electromagnetic actuator components include a magnetic core, a conductor assembled with the core and defining a winding completing a number of turns, and a movable component that may be displaced by a magnetic field. The conductor is fabricated from a composite material including carbon nanotubes having an improved conductivity. The conductor has a cross section defined by an effective diameter. The conductor is fabricated to have performance parameters that are selected in view of a function of a ratio of conductivity and/or a function of a ratio of effective diameter of the composite conductor material relative to a reference conductor material as conventionally used in an electromagnetic actuator fabrication.
Abstract:
Electromagnetic transformer components include a magnetic core and at least two conductors assembled with the core and defining respective windings completing different numbers of turns. The conductors are fabricated from a composite material including carbon nanotubes having an improved conductivity. The transformer is fabricated to have performance parameters that are selected in view of a function of a ratio of conductivity and/or a function of a ratio of effective diameter of the composite conductor material relative to a reference conductor material as conventionally used in a transformer fabrication.
Abstract:
A multi-port power switch device may intelligently detect whether a portable electronic device is connected to one of the output ports provided. The output ports can automatically be switched on and off as needed depending on whether they are connected to a portable electronic device.

Abstract:
A charger appliance configured to determine a no-load, disconnected state from an electronic device having a rechargeable battery, and configured to determine a connected state of the charger with an electronic device in which recharging power may be supplied through the charger to the electronic device. Automatic connection and disconnection of a mains power supply is made depending on the detected state of the charger to avoid wasteful energy consumption in a no-load state. State detection may be determined by monitoring a voltage on one or more signal lines associated with the electronic device.

Abstract:
A non-contact magnetic sensor assembly includes a thin-walled magnetic ring that facilitates a reduction in the size of the device without compromising performance. The component assembly may be configured as a Hall effect current sensor and may be included in a string monitor for a photovoltaic power system.
