Methods and apparatus of the invention allow the coordination of resources of mobile computing devices to jointly execute tasks. In the method, a first gesture input is received at a first mobile computing device. A second gesture input is received at a second mobile computing device. In response, a determination is made as to whether the first and second gesture inputs form one of a plurality of different synchronous gesture types. If it is determined that the first and second gesture inputs form the one of the plurality of different synchronous gesture types, then resources of the first and second mobile computing devices are combined to jointly execute a particular task associated with the one of the plurality of different synchronous gesture types.

An affiliation manager provides each of typically hundreds of users with a calendar of appointments and a task list each including icons for capturing time and expenses accrued by the user when attending a particular appointment or performing a particular task. A subset of collected captured time and expenses may be transferred to each requesting client for use by independent accounting systems. Management of appointments and tasks from a central database promotes collaboration among users, simplifies sharing of schedule information among users, and provides context for data entry. Each user may create any number of affiliations, each affiliation describing affiliations of the user in numerous projects, organizations, employments, and activities. Each user may admit other users to share his or her affiliations, thereby promoting collaboration of many users for jointly attending meetings and jointly performing tasks. Context permits automatic intuitive association of email, chat messages, notes, and documents to records for persons, locations, resources, appointments, tasks, and projects for integrated affiliation management services. Requests for queries and forms are interpreted according to the context in which the user issued the request. Requests are made via a common set of icons and links on each item of a list provided by a prior query.

Joint execution type compound orders can be processed in an anonymous trading system comprising a plurality of broker nodes each of which includes an order matching functionality and a market distribution functionality. Trader agent nodes are connected to a number of dealer terminals grouped in trading floors and also to a broker node. Joint execution orders are entered as hit orders and are all matched by the broker during the hit or the order is cancelled. If matches are made the taker's trading agent does not complete any of the deals marking up the order until it knows that all the deals are executable. The system may be used to allow traders to hit bids and offers in currency pairs synthesized from other currency pairs. In this arrangement the dealer enters a simple order in the synthetic currency and the taker's trading agent converts it into a joint execution order.

A plurality of wirelessly communicating sensing microsystems is provided, each sensing microsystem including a temperature sensor and a processor, at least one of the sensing microsystems being coupled to an HVAC unit for control thereof. The plurality of sensing microsystems is configured to jointly carry out at least one shared computational task associated with control of the HVAC unit. Each sensing microsystem includes a power management circuit configured to determine an amount of electrical power available for dedication to the at least one shared computational task. The at least one shared computational task is apportioned among respective ones of the plurality of sensing microsystems according to the amount of electrical power determined to be available for dedication thereto at each respective sensing microsystem.

An encoder achieves improved encoding efficiency by initially limiting consideration of the potential modes (block sizes) to a prescribed sub-set and by performing mode estimation jointly with mode decision-making. An initial sub-set of modes is considered and an estimation of the motion for each block in the sub-set is made to establish a best motion vector. A distortion measure is also made for each sub-set. From the distortion measure, a determination is made whether or not to estimate the motion for other block sizes. If not, then an encoding mode is chosen in accordance with the estimated motion. In this way, motion estimation on all possible block sizes need not be undertaken.

One embodiment of the present invention sets forth a technique providing an optimized way to allocate and access memory across a plurality of thread/data lanes. Specifically, the device driver receives an instruction targeted to a memory set up as an array of structures of arrays. The device driver computes an address within the memory using information about the number of thread/data lanes and parameters from the instruction itself. The result is a memory allocation and access approach where the device driver properly computes the target address in the memory. Advantageously, processing efficiency is improved where memory in a parallel processing subsystem is internally stored and accessed as an array of structures of arrays, proportional to the SIMT/SIMD group width (the number of threads or lanes per execution group).

A method and apparatus for signal acquisition in an OFDM receiver relies on a preamble training sequence to synchronize the receiver in time (e.g. determining the start of a frame) and in frequency (carrier frequency offset compensation). The preamble training sequence has a periodic structure and the method and apparatus perform a cross-correlation technique using a matched filter to achieve time synchronization and/or frequency synchronization and/or channel estimation, the latter being especially useful in multi-antenna receivers for diversity combining purposes. Many advantages derive from performing at least two and preferably all three operations jointly, in terms of latency, hardware complexity, and length of training sequence required to achieve satisfactory convergence on all counts. The periodicity of the training sequence is exploited to reduce considerably the main filter complexity and optionally dynamically adjust carrier offset compensation throughout the filtering process, thus improving the quality of all final estimates (carrier frequency offset, time synchronization, and channel).

An assembly includes multiple adjoined rotor sections each having multiple poles and multiple void rows therethrough that are radially distributed in each of the poles. The rotor sections are skewed in a circumferential direction. The assembly also has multiple conductive rings that substantially surround one of the void rows. A method of assembly and electric machines and vehicles using the assembly are also disclosed. Aspects reduce torque ripple in electric machines and allow for encoderless/sensorless operation in an electric machine using the rotor assembly. The present invention has been described in terms of specific embodiment(s), and it is recognized that equivalents, alternatives, and modifications, aside from those expressly stated, are possible and within the scope of the appending claims.

An apparatus and method are provided for simply estimating joint channel and Direction-of-Arrival (DOA) to efficiently estimate a channel impulse response associated with a spatially selective transmission channel occurring in a mobile radio channel, and performing efficient beam forming using the simplified joint channel and DOA estimation are provided. A receiver estimates the total interference power using power for each interference signal, estimates a spectral noise density, calculates steering vectors considering predetermined DOAs, and jointly calculates optimal weight vectors for each DOA of each user by applying the interference power and the spectral noise density to the steering vectors. The beam forming reduces implementation complexity of a TDD system such as a TD-SCDMA and increases beam forming efficiency in a mobile environment by efficiently using spatial diversity.

A filtering method approximates a target Finite Impulse Response (FIR) (or transversal) filter and reduces computational requirements by eliminating high pass filtering required by known multi-rate filters. An input signal is copied into two identical signals and processed in parallel by a full-rate path, and by a reduced-rate path. Parallel filters are computed and applied in each path, the reduced-rate signal is up-sampled, and the two signals summed. The high pass filter required by known multi-rate filters is eliminated and the low pass filter in the prior art is implicit in a down sampling. Linear phase FIR filters are used for down and up sampling, resulting in constant group delay. Added benefits include the option of zero added latency through the filtering and the constant group delay added to the target FIR. The user may choose criteria such as minimum resolution in each band.

A cryptographic method is implemented in a white-box implementation thereof. The method comprises applying a plurality of transformations (802) each replacing an input word by an output word, and applying a diffusion operator (804) to a concatenation of a plurality of the output words for diffusing information represented by the output words among the output words. A key (806) to the cryptographic method comprises information representing the diffusion operator. The diffusion operator satisfies a property that a change of one bit in an input to the diffusion operator corresponds to a change of more than one bit in an output of the diffusion operator.

A communication system that allows communication devices to synchronize the transfer of data to allow the devices to wirelessly and efficiently communicate in a star or mesh network. The communication system operates in the presence of other communication systems noise sources using a spread spectrum frequency hopping transmission scheme to efficiently generate adaptive frequency hopping patterns that are unique to the members of the wireless network based on a network identification code. The communication system employs a predictive retrieval of data for transmission from one device storing the data to a requesting device. A communication device transfers communication from a first network to a second network when the device has been moved beyond the range of the first network, where the second network is in communication with at least one other member device of the first network.
