20090081944 | TECHNIQUES FOR DISTRIBUTING CONTENT TO MULTIPLE DEVICES IN A COMMUNICATION NETWORK - This disclosure describes techniques for scheduling distribution of content to a plurality of devices in a communication network, such as a cellular-based wireless network. According to this disclosure, two or more distribution techniques may be used, and scheduling techniques are performed to determine which distribution technique to use for different content. For example, content can be broadcast to all devices on the network (broadcast), multicast within several cells of the network (multi-cell multicast), multicast in a specific cell of the network (single cell multicast), or unicast to one or more specific devices within specific cells of the network (unicast). The scheduling techniques described in this disclosure may improve content distribution by substantially maximizing the number of content requests that are satisfied, particularly when bandwidth is limited. | 03-26-2009 |
20100080189 | METHOD AND APPARATUS FOR PLUG-AND-PLAY VENUE-CAST CO-CHANNEL WITH WIDE-AREA NETWORK - A system, method, and apparatus for providing venue-cast service in a wireless access network are disclosed. A local transmitter can request reservation of air link resources on the wireless access network for a venue-cast transmission. The local transmitter can receive a forward link signal with a timing reference for data transmitted on the wireless access network such as, for example, the forward link signal in an EV-DO network or a FLO-based media distribution system. Based on the timing reference, the local transmitter can transmit venue-cast information in a same frequency band as the forward link signal utilizing the reserved air link resources. Optionally, the venue-cast system can include a collocated network repeater and the local transmitter can synchronize its timing and transmit power to the forward link signal from the repeater. | 04-01-2010 |
20100201189 | WIRELESS POWER TRANSFER FOR VEHICLES - Exemplary embodiments are directed to wireless power transfer. A power transmitting device is attached to an existing vehicle item or is embedded in a vehicle element. The power transmitting device includes a transmit antenna to wirelessly transfer power to a receive antenna by generating a near-field radiation within a coupling-mode region. An amplifier applies a driving signal to the transmit antenna. A presence detector may detect a presence of a receiver device within the coupling-mode region. The presence detector may also detect a human presence. An enclosed compartment detector may detect when the vehicle element is in a closed state. A power output may be adjusted in response to the closed state, the presence of a receiver device, and the presence of a human. | 08-12-2010 |
20100207572 | WIRELESS POWER FROM RENEWABLE ENERGY - Exemplary embodiments are directed to wireless charging. A charging system may comprise at least one power generation system configured to convert renewable energy to another form of energy and convey the another form of energy. The charging system may further include at least one transmit antenna coupled to the at least one power generation system and configured to receive the another form of energy from the at least one power generation system. Further, the at least one transmit antenna is configured to wirelessly transmit energy to at least one other antenna positioned within an associated coupling-mode region. | 08-19-2010 |
20110149863 | METHODS AND SYSTEMS FOR PROVIDING ENHANCED POSITION LOCATION IN WIRELESS COMMUNICATIONS - Embodiments disclosed herein relate to methods and systems for providing improved position-location (e.g., time-of-arrival) measurement and enhanced position location in wireless communication systems. In an embodiment, an access point may replace information (e.g., data) transmission by a “known” transmission (or “reference transmission”) at a predetermined time known to access terminals in the corresponding sectors. The access terminals may use the received reference transmission to perform a position-location measurement, and report back the measured information. The access point may also send a reference transmission on demand, e.g., in response to a request from an access terminal in need for a location-based service. | 06-23-2011 |

20130344798 | METHODS AND APPARATUS FOR PROVIDING HYBRID UNICAST BROADCAST SERVICES - A method, an apparatus, and a computer program product are provided in connection with facilitating hybrid unicast/broadcast service distribution. In one example, a communications device is equipped to provide a parity portion of titles in a channel of a service to a plurality of UEs at a first time, receive, from a UE at a second time, a request to access a title of the one or more titles, and provide an enablement item, to the requesting UE, which is a portion of the requested title that, when processed with the provided parity portion of the requested title, is sufficient to allow the requesting UE to decode and access to the requested title. In an aspect, the parity portion may be a parity portion of a fountain code encoded title, and the enablement item may be repair symbols of the fountain code encoded title. | 12-26-2013 |

20150070323 | DISPLAY-TO-DISPLAY DATA TRANSMISSION - A display device may include a display, an optical touch system proximate the display and a control system. The control system may be capable of receiving input for initiating a peer-to-peer data transfer and of performing an authentication process for the peer-to-peer data transfer. The authentication process may involve obtaining fingerprint images via the optical touch system. The display device may provide a prompt to position the display device proximate a second device, e.g., with the display adjacent to a display of the second device. The display may display data transfer parameters for the peer-to-peer data transfer. The optical touch system may receive a confirmation that the second device received the data transfer parameters. The peer-to-peer data transfer may be performed, at least in part, by an array of optical transceivers. | 03-12-2015 |
