摘要:
A method and system for managing data between a plurality of electronic devices in a Near Field Communication (NFC) network are provided. The method is performed at a first electronic device. A request is received from a second electronic device to send context data. The context data is then represented in accordance with a context Record Type Definition (RTD). The context RTD is used for defining context data in the NFC network. The context data that is represented in accordance with the context RTD is exchanged with the second electronic device.

The present invention provides a method and apparatus for device synchronization and power conservation in a wireless communication system. In one embodiment, a method of a communication device for device synchronization and conserving power includes determining one or more device parameters in a wireless communication system, where the one or more device parameters are indicative of one or more time slots and at least one additional guard slot required during data transaction. The method also includes forming a connection request including the one or more device parameters, and communicating the connection request to a controller in the wireless communication system. Moreover, the method includes receiving a connection assignment frame including a device allocation interval from the controller based on the one or more device parameters, wherein the device allocation interval includes the one or more time slots and the at least one additional guard slot allocated to the communication device for data transaction.

Disclosed are a method for media access controlling and channel time reservation system and method in distributed wireless personal area networks. A method of media access controlling for a distributed wireless network including at least one device, includes a device of the distributed wireless network, generating a data slot reservation indicator for devices of the same beacon group, and the device, broadcasting the generated data slot reservation indicator. Thus, a slot reservation for communication between devices can be completed in a shorter period of time. Also, capacity of the network can be improved by spatial reuse of channel time.

The present invention proposes a method for protecting and monitoring removable entities in an embedded system. In accordance with the present invention, prior to insertion of a removable entity in the embedded system, a user registers details of the removable entity in the device host. The details may be entered after entering a password or a PIN. A registration identification is calculated based on an algorithm in the device host and is then stored in the host. After the removable entity is inserted, it is registered in an unalterable area (e.g. flash memory) of the device host. Information such as the category of the removable entity, a device number, etc. may be exchanged between the device host and the removable entity. The device host then computes a registration identification based on a Removable Entity Registration Algorithm. The identifications are then compared, and the device host displays the details of the removable entity to the user.

The present invention provides an ultra-wide band (UWB) system and method. In one embodiment, a transmitter of a low duty cycled ultra wide band (UWB) system includes a differential spreading encoder for encoding a phase of a bit sequence based on a reference bit sequence. The transmitter also includes a pulse generator for generating a number of pulses associated the bit sequence using the encoded phase of the bit sequence, where the number of pulses is equal to a length of the bit sequence. Moreover, the transmitter includes a DMPSK modulator for generating a modulated signal through modulating the number of pulses using a phase of a differential data symbol.
