| 20100150128 | Devices and Methods for Asymmetrical Multicarrier Transmission and Reception - Devices and methods are disclosed which supplement a duplex frequency by providing one or more simplex frequencies and distributing a data load among them. Variations of the disclosed system include a server containing a scheduler in communication with a communications device. The server initially communicates with the communications device using a duplex channel. The scheduler determines when it is no longer optimal to use the single duplex channel, and distributes data among the duplex channel and one or more simplex channels. Before sending this data through multiple channels, the server must first send a schedule to the communications device, so the communications device knows 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. | 06-17-2010 |

| 20110149168 | SYSTEM AND METHOD FOR BROADCAST STATION ADJACENCY - Disclosed herein are systems, methods, and computer-readable storage media for broadcasting signals. The system includes a supplemental antenna at a first location co-located with a main antenna transmitting a main signal. The supplemental antenna is physically separate from a main antenna at the same location and transmits a supplementary signal adjacent to the main signal which matches or corresponds to a remote signal transmitted from an antenna at a remote location. The system transmits the supplemental signal at sufficient power to overcome interference in a coverage hole of the remote signal caused by the main signal. A supplemental antenna co-located with the main antenna can transmit the supplemental signal. The system can receive a supplemental signal that matches a remote signal, pass the supplemental signal through a same power amplifier and filter as a local main signal, and broadcast via an antenna both the main signal and the supplemental signal. | 06-23-2011 |

| 20080258680 | PORTABLE BATTERY RECHARGE STATION - A system and method for recharging secondary batteries. One embodiment of the present invention comprises a supervisory circuit, a voltage converter, a portable power source, and one or more of a holder and a socket. The holder is adapted to receive a specific type of secondary battery of a portable device. The socket is adapted to mate with a plug of a device-specific charging cord connected to the portable device. Each of the holder and the plug can be associated with a programming resistor that provides a voltage requirement of the secondary battery. When the secondary battery is either placed in the holder or is connected to the socket, the supervisory circuit communicates with the voltage converter to supply the appropriate voltage required to recharge the secondary battery. The voltage converter receives power from the portable power source. The voltage converter can convert the voltage of the portable power source up (i.e., increasing the voltage) or down (i.e., decreasing the voltage) as appropriate to recharge the secondary battery as instructed by the supervisory circuit. The portable power source of the portable battery recharge station can be one of several types of power sources. For example, the portable power source can be replaceable, rechargeable, or renewable. | 10-23-2008 |
| 20090156227 | OPTIMAL UTILIZATION OF MULTIPLE TRANSCEIVERS IN A WIRELESS ENVIRONMENT - Switching between and/or combining various multi-transceiver wireless communication techniques based on a determined characteristic of a network or a wireless link is described herein. As an example, a characteristic such as signal to noise ratio (SNR), multi-path scattering, available bandwidth, or the like, can be determined.
