Devices and methods for asymmetrical multicarrier transmission and reception
A duplex frequency is supplemented by providing simplex frequencies and distributing a data load among them. A server initially communicates with a communications device using a duplex channel. A scheduler of the server determines when it is no longer optimal to use the single duplex channel, and distributes data among the duplex channel and the simplex channels. Before sending this data through multiple channels, the server first sends a schedule to the communications device to inform which bits of data are coming through which channels at which times. The scheduler compiles this schedule and sends it to the communications device through the duplex channel. A descheduler within the communications device receives the schedule and alerts the communications device to start receiving data on other simplex channels. The descheduler then puts the bits of data in order as they stream in across the duplex and simplex channels. |

Magnetic momentum transfer generator
A magnetic momentum transfer generator utilizes three or more magnets aligned with each other. A first control magnet is positioned outside a coil. A second magnet is positioned within the windings of the coil and a third magnet is positioned on the opposite side of the coil opposite the control magnet. When the control magnet rotated or moved, mutual magnetic flux lines generated by all three magnets and passing through the coil winding are aligned at right angles to the coil, thereby inducing a maximum voltage at the terminals. This generator is particularly useful for short burst radio micro-transmitters that can be used for battery-less and wireless switching applications. |
