US Classification:

370350, 370208, 370328

Abstract:

A highly bandwidth-efficient communications method is disclosed that enables remote stations to synchronize in time and frequency to their serving base station. The invention enables a base station and its remote stations in a cell to synchronize in a noisy environment where signals interfere from other base stations and remote stations in other cells. The base station forms a forward synchronization burst that includes a plurality of tone frequencies arranged in a distinctive orthogonal frequency division multiplexed pattern unique to the base station. The unique pattern enables a remote station to distinguish the base stations bursts from other signals present in a crowded area. The distinctive orthogonal frequency division multiplexed pattern can be a Hadamard code pattern, for example. When the a base station has received a signal on a reverse link from a remote station, having significant interference, the base station selectively forms a request signal requesting the remote station to respond with a reverse synchronization burst that includes a plurality of tone frequencies arranged in the same distinctive orthogonal frequency division multiplexed pattern. The base station then transmits the forward synchronization burst and the request signal at a base station reference instant of time to the remote station.

Abstract:

A beverage infusion device comprises a handle and a support member extending from the handle having a pair of flat legs spaced apart by a predetermined width. Attached to each side of the flat legs is a flexible porous member, for example, a pouch of filter material having an unfolded width greater than the width of the support legs. Each porous member contains an infusible beverage preparation and is supported by the support legs in a folded position wherein, upon immersion of the porous members in a liquid, the porous members expand and become spaced to facilitate infusion of a beverage preparation therein into the liquid. In the folded position, the porous members may have a plurality of folds across its width, for example, folds adjacent the first and second ends and an unfolded portion therebetween. The first and second ends of the porous member are preferably heat bonded to the support legs. The device handle is of a configuration to fit between the pair of legs such that the handle and the legs may be stamped from a single piece of flat stock of paper- or plastic-based materials.

US Classification:

370208, 370210

Abstract:

A fixed wireless system (FWS) utilizing Orthogonal Frequency Division Multiplexing (OFDM) communication techniques is spectrally efficient and responsive to communications involving both voice and high speed data, such as Internet data. The FWS includes a wireless base unit; a plurality of fixed wireless remote units; a plurality of wireless data traffic channels available between the wireless base unit and the plurality of fixed wireless remote units; and a plurality of wireless voice traffic channels available between the wireless base unit and the plurality of fixed wireless remote units. Each wireless traffic channel is identifiable by a unique combination of frequency and time slots. Each wireless data traffic channel is used for carrying high speed data in addressed data packets to and from the plurality of fixed wireless remote units. On the other hand, each wireless voice traffic channel can be assigned and dedicated to a particular voice communication call involving one of the plurality of fixed wireless remote units for carrying voice data of the call.

International Classification:

H04Q 7/24

US Classification:

370252, 370338

Abstract:

A networked computing system including multiple network base stations, user equipment, and a data communications network facilitating communications amongst all devices of the networked computing system. The radio frequency isolation between two network base stations is determined by taking measurements of a radio operating parameter associated with at least one interference source. A regional network device located near one of the two base stations is configured measures the radio operating parameter on a periodic basis and then transfers the measurements to a radio communications controller. The radio communications controller then allocates network communications resources to user equipment, and optionally designates radio operation levels for one or more network base stations, based on a comparison of the received measurements to known broadcast levels of the radio operating parameter.

Abstract:

A networked computing system, including multiple radio access nodes (RANs), multiple radio communications controllers (RCCs), and a data communications network facilitating communications amongst the RANs and the RCCs of the system. A regional RAN receives a default eMIB associated with a first type of RAN (e. g. , a macrocell, microcell, picocells, or femtocell RAN types) from a RCC, in response to a registration event of a RAN initialization process. The regional RAN maintains a dynamic eMIB comprising network operating parameters determined by various self-optimization processes. The network operating parameters of the dynamic eMIB are selected to fall within a range designated by the default eMIB. During a network failure condition, the regional RAN is configured to use a temporary eMIB comprising failure level operating parameters in order to mitigate network deficiencies caused by the network failure condition.
