Abstract: A base station selectively communicates with terminals using first and second separately allocated frequency bands, e.g., separate cellular/PCS bands, of a government spectrum allocation based on propagation conditions between the base station and the terminals. The base station may transmit in the first frequency band and receive in the second frequency band during a first time slot and transmit in the second frequency band and receive in the first frequency band during a second time slot. The base station may transmit to a terminal in the first frequency band while receiving from the terminal in the second frequency band during the first time slot and may transmit to the first terminal in the second frequency band while receiving from the first terminal in the first frequency band during the second time slot.

Abstract: A satellite radioterminal communications system may include first and second space-based components and a return link diversity combiner. The first space-based component may be configured to communicate uni-directionally and/or bidirectionally with a first radioterminal over a first forward link using a first band of frequencies and/or over a first return link using a second band of frequencies. The second space-based component may be configured to communicate uni-directionally and/or bidirectionally with a second radioterminal over a second forward link using a third band of frequencies and/or over a second return link using a fourth band of frequencies. The second space-based component may also be configured to receive return link communications from the first radioterminal over the first return link using the second band of frequencies, and the first and third bands of frequencies may be different bands of frequencies.

Abstract: Systems and methods for an item placement configuration optimization are provided. A system and method can include receiving a first selection including two or more first items corresponding to a first level in an item placement configuration. A first score is determined for the first selection by applying an algorithm to data corresponding to the first items. A second selection including two or more second items and corresponding to a second level in the item placement configuration is received. A second score for the second selection is determined by applying an algorithm to the first score and data corresponding to the second items.

Abstract: A signal strength that is associated with a first wireless communications channel is detected. Electromagnetic energy is transmitted over the first wireless communications channel in response to the signal strength being sufficiently weak. A determination is made whether a handoff should be made to a second wireless communications channel having a signal that is weaker than a signal of the first wireless communications channel. Related systems and methods are described.

Abstract: A system (10) and method (30) comprises a detector that is configured to enable a mode of a first device (14) and/or to enable a mode of a second device (15) responsive to a detection that a proximity criterion is satisfied between the first device and an entity (Entity 1) and responsive to at least one of a position, velocity and a Time-of-Day and where the second device is not the entity and is not associated with the entity, and where the entity is not involved in providing a communications service to the first and/or second device.

Abstract: A system (10) and method (20) includes transmitting (22) Service Related (SR) data (15, 16, or 17) from each one of a plurality of networks (11, 12, and 13), receiving and processing (24) at a device (14) the SR data from each of the plurality of networks, and identifying (26) at the device a first network that satisfies a Bid Policy (BP) (19) responsive to the receiving and processing of the SR data. The identifying can be done by comparing (28) SR data with the BP. The method can then establish communications (34) preferentially with the “first network” responsive to the identifying. Note that the SR data can include terms of an offer for service including a financial term. The BP as well as the SR can have a plurality of components such as a Cost-of-Service (CoS), a Quality-of-Service (QoS), and a data rate among others.

Abstract: A system (10) and method (50) of dynamic allocation of spectrum for a communication device involves receiving (51) a user channel map (UCM) on a control channel that is outside the band of interest. The UCM can include at least boundary location information for one or more channel resources within a UHF band and communication parameters. The method can determine (52) at least an approximate location for the communication device, compare (56) the approximate location with the boundary location information, and determine (57) which channels can avoid co-channel and adjacent channel interference with licensed users and other unlicensed users based on the comparison, boundary location information, and the communication parameters. The UCM can further include communication parameters such as maximum allowable transmit power, duty cycle, and in use information by other unlicensed and licensed users.

Abstract: A system (10) and method (50 or 70) of dynamic allocation of spectrum for a communication device where a UHF band is currently unused for licensed television broadcasting involves determining (51) a location of a user device using GPS or other signals (such as television broadcast signals) received at the user device using signal strength or time distance of arrival of those signals. The method can determine (52) which UHF television broadcast channels are available for use by the user device and determine (53) a maximum allowed transmission power for a given channel based on signal strength for the given channel and on adjacent channels before transmitting (54) the maximum allowed transmission power and location by the user device to a remote server for sharing information. The method can receive (55) polygon endpoints from a television broadcast defining the location of usable reception of the television broadcast.

Abstract: Methods are disclosed for determining minute quantities of an analyte in a medium suspected of containing the analyte. One method comprises treating a medium suspected of containing an analyte under conditions such that the analyte, if present, causes a substrate having an oxidant cleavable linker and a photosensitizer to come into close proximity. The photosensitizer generates singlet oxygen which oxidatively cleaves the linker to form a product which can be detected in a sandwich detection assay such as LOCI. The amount of product detected is related to the amount of analyte in the medium. Compositions, kits, and compounds are also disclosed.
