The present invention relates to methods, a coordinator and a device for switching coordinator in a personal area network. A method for switching coordinator in a personal area network including at least one coordinator and at least one device includes the steps of transmitting, by a coordinator, identification information of a new coordinator determined based on a location of the at least one device, to a device associated with the coordinator and releasing, by the coordinator, an association between the coordinator and the device.

A method, an apparatus, and a system for switching coordinators in a Personal Area Network (PAN) are provided. The method includes initiating a request for switching at least one device present in a network session to a first priority PAN coordinator, the initiated request including a count of the at least one device, transmitting the initiated request to the first priority PAN coordinator, the initiated request including a requirement for supporting the at least one device of that count, determining whether the first priority PAN coordinator is capable of supporting the at least one device, and switching, when the first priority PAN coordinator is capable of supporting the at least one device, the network session of the at least one device with the first priority PAN coordinator to facilitate establishment of the network session with the first priority PAN coordinator.

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.

The present invention provides an integrated medium access control for processing respectively separated traffic situation sets. Another aim of the present invention is to optimize power consumption during a poll based operation of the medium access control mechanism. An additional aim of the present invention is to provide a poll-based error recovery mechanism for achieving preferred application reliability through power-and cost-efficient methods. A further aim of the present invention is to provide an in-band wakeup method for a medical implant device in a human body area network. Still a further aim of the present invention is to provide a method for a medical implant device in a human body area network. An even further aim of the present invention is to provide a method for simultaneously accessing a power channel of a poll-based minimum level and operating a plurality of BANs in medical implant communications.
摘要:
A method and system for managing a body area network using a coordinator device. The method includes acquiring a medical implant communication service (MICS) channel by an MICS transceiver in the coordinator device. The method also includes sending a signal, indicative of a wake-up process, in a non-MICS channel to an implant device and a command signal, indicative of joining a piconet, by the MICS transceiver to an implant device. Further, the method also includes receiving an acknowledgement signal by the MICS transceiver of the coordinator device based on the sending of the command signal to the implant device. The acknowledgement signal comprises a security control field. Furthermore, the method includes initiating security procedures based on the security control field. Further, the method also includes exchanging data between the coordinator device and the implant device based on the initiating and disassociating the implant device by sending a command message.

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. A registration identification is calculated in the device host and is stored in the host. After the removable entity is inserted, it is registered in the device host. Information of the removable entity may be exchanged between the device host and the removable entity. The device host computes a registration identification. The identifications are compared and the device host displays the details of the removable entity.
