摘要:
A system for interacting with a physical entity includes a user-wearable terminal and a mobile station. The user-wearable terminal is capable of automatically receiving a selection of a physical entity as at least a portion of a user wearing the terminal moves into proximity with the entity thereby moving the terminal into proximity with the entity. The terminal includes a first short-range communication element for receiving information from the entity at least partially over an air interface. In addition, the terminal includes a second short-range communication element for transferring input data to the mobile station at least partially over an air interface, where the input data is based upon the information related to the entity. The mobile station, upon receiving the input data, is capable of performing at least one action based upon the input data.

A system for cryptographically authenticated communication, wherein an activation signal is sent from a communications device to a memory device (410). The memory device derives a random challenge from at least one physical property of the activation signal and sends it back to the communications device (420). A signature is computed using the received random challenge (440) and sent, together with a certificate, to the memory device (450).

An apparatus facilitating a direct memory copy among devices may include a processor and memory storing executable computer code causing the apparatus to at least perform operations including exchanging content with a device via a near field communication responsive to entering a proximity of the device. The computer program code causes the apparatus to detect an item(s) of data of a block(s) of local memory for remote access and negotiate, via communications across a first interface, with the device to determine whether the device desires receipt of the item(s). The computer program code causes the apparatus to provide, via a second interface, the item(s) of data to the device, within the proximity, responsive to a received indication from the device requesting the item(s) to enable the device to store the item(s) of data in an agreed upon block(s) of remote memory. Corresponding methods and computer program products are also provided.

A method and apparatus are provided for receiving compressed sensed data at a device and providing for decompression of the compressed sensed data at a delegated resource. A method of using resources may be provided with superior processing capacity and/or power capacity for computationally intensive decompression of compressed sensed data. A method may include determining a target recipient device for decompressed data, determining the appropriate decompressed data format for the decompressed data, and determining a delegated resource to select for decompression of the compressed sensed data. The method may further include providing for transmission of the compressed sensed data to the delegated resource.

In a mobile environment, a mobile device includes an attached memory stick (removable memory) having a high speed—memory and storage with direct memory access embodied in an integrated circuit chip coupled to an ultra-wideband (UWB) transceiver. The mobile device communicates with other like base devices, portable or stationary, via UWB transmissions using pulse bursts up to 1 Gbit per second. Data transfers between the devices occur in the simplex or duplex mode, after a low power communication connection is established between the devices. The communication link between the devices is in the range of 10-20 meters. The communication system allows existing device bus interfaces (which are much slower than ultra-wideband transmissions) to communicate between the fast read/write cycles of the memories integrated within the memory stick. Duplex transmission can occur by pulse interleaving sending side transmitters and receiving side transmitters.

摘要:
An approach is provided for managing access rights of users to information spaces using signatures stored in a memory tag. A signature manager caused reading of a memory tag to initiate a request, from a device, for an initial access to an information space. The request includes an authorization signature associated with the device. The signature manager determines a level of access to the information space by comparing the authorization signature against a lattice of signature primitives associated with the information space. The signature manager then modifies the authorization signature based on the determination and stores the modified authorization signature for validation of subsequent access to the information space by the device.

The present invention provides techniques for spatial reuse in wireless communications networks. Accordingly, the present invention provides A device participates in a wireless communications network. The network has a shared transmission medium for the exchange of communications traffic. Further, the device determines a value for at least one interference condition in the shared transmission medium of the wireless communications network. Based on this value, a planned transmission to a remote wireless communications device is scheduled. For instance, when this value is less than a predetermined threshold, this scheduling employs a time-overlapping access technique.

摘要:
A method of manipulating the header field in an ATM cell. In accordance with the method, the ATM cell is transferred via an interface where each byte of the cell appears in a parallel form on a plurality of parallel data conductors and where information on the start of cell (SOC) is also available. In order to be able to carry out header bit manipulation in a simple manner at such an interface, data conductors corresponding to the bits to be manipulated are led to a circuit carrying out the manipulation, and the other data conductors are led past the circuit. The bit to be manipulated is searched for by counting from start of cell up to the byte containing the bit to be manipulated, after which the bit is manipulated. An output conductor corresponding to the manipulated bit is led from the manipulation circuit to its own position among the data conductors that bypassed the circuit.
