GENERATION AND USE OF ELECTRIC FIELDS FROM CAPACITIVE EFFECTS OF A SOLENOID

摘要

Systems, apparatuses, and methods are provided for producing a directional electric field from an end of the solenoid in an efficient manner. For example, voltage pulses can be used to charge the turns of the coil so that the coil acts as a capacitor. The voltage pulses can be of a specified time width (e.g., 1 μs or less) so as to reduce the amount of current flowing in the coil, and thus reduce the input power used in the coil. The electric field can be used for a variety of purposes, e.g., for charging or communication. An output conductor can be positioned such that electrons can be moved in the output conductor. The motion of electrons can correspond to the communication of data or be used to operate a load (e.g., in charging a device or otherwise providing power).

主权项

1. An apparatus comprising:
an input coil comprising a plurality of windings of a conductor, the input coil having a first end that is separated from a second end; a power supply circuit selectably connected to the input coil; a switching mechanism coupled between the power supply circuit and the input coil and configured to connect and disconnect the input coil to the power supply circuit; a controller communicably coupled with the switching mechanism for controlling a connection state of the switching mechanism, wherein the controller is configured to control the switching mechanism such that the power supply circuit provides a series of input voltage pulses to the input coil, thereby creating a directional electric field from the first end of the input coil; and an output conductor positioned to receive the directional electric field.
