Abstract: A system and method for providing wireless communications between a medical controller hub and an implant node are disclosed. The hub transmits signals to facilitate communication connections with the node. The signals include connection invitation polls with identification parameters. A node monitors the hub's transmissions for the connection invitation polls. When a poll is detected, the node compares the identification parameters to a list of preferred identification values. If the received identification parameter is on the preferred list, and the node and hub are not already connected, then the node responds to the connection invitation poll. If the received identification parameter is not on the preferred list, then the node continues to monitor hub transmissions for other connection invitation polls that include identification parameters that are on the preferred list.

Abstract: A method for pairing a key fob with a vehicle is provided. A pairing device and a key fob execute an ID authenticated key agreement protocol based on a KFID to authenticate one another and to generate an encryption key DHKey1. The pairing device encrypts a control unit identification (CUID) with DHKey1. The pairing device transmits the encrypted CUID to the key fob. The key fob and a control unit executes an ID authenticated key agreement protocol based on the CUID to authenticate one another and to generate an encryption key DHKey2. The control unit encrypts an operation key with DHKey2 and transmits the encrypted operation key to the key fob.

Abstract: A system and method for minimizing or preventing interference between wireless networks is disclosed. A network hub broadcasts a beacon signal within repeating beacon periods. The position of the beacon signal shifts within each beacon period based upon a predetermined pseudo-random sequence. The beacon signal includes data identifying the current beacon shift sequence and the current phase of the sequence. Neighboring hubs independently or jointly determine and broadcast their own beacon shift sequences and phases for their respective networks from a predetermined list. Nodes connected with the network hubs are assigned allocation intervals having a start time that is set relative to the beacon signal. The start time and duration of the allocation interval wraps around the beacon period if the allocation-interval would otherwise start or continue in a next beacon period.

Abstract: A system and method for providing communications between a hub (medical controller) and a node (an implant) are disclosed. The hub selects an operating channel within a channel group in accordance with applicable regulations, and transmits signals to facilitate communications with nodes. A node sequentially tunes to individual channels within the group, monitoring each channel for a hub transmission during a monitoring period. If a hub transmission is detected, the node stays on the current channel. Otherwise, the node tunes to a next channel in the channel group. The hub transmission may be directed to unconnected nodes, to a single connected node, or to a group of connected nodes. The node transmits a first frame to the hub at a designated transmission time and receives a response. The node reports an emergency by sequentially transmitting emergency frames on each of the channels until receiving an acknowledgment from the hub.

Abstract: Apparatus and methods implement aggregation frames and allocation frames. The aggregation frames include a plurality of MSDUs or fragments thereof aggregated or otherwise combined together. An aggregation frame makes more efficient use of the wireless communication resources. The allocation frame defines a plurality of time intervals. The allocation frame specifies a pair of stations that are permitted to communicate with each other during each time interval as well as the antenna configuration to be used for the communication. This permits stations to know ahead of time when they are to communicate, with which other stations and the antenna configuration that should be used. A buffered traffic field can also be added to the frames to specify how much data remains to be transmitted following the current frame. This enables network traffic to be scheduled more effectively.
