  • Patent number: 10275961
    Abstract: Methods and apparatus are provided for handling the response sequence with geometric elimination of a plurality of keyless fobs. The remote fobs are interrogated with a body control module. A first signal is issued from a first set of remote fobs in a first time slot in response to the interrogation signal from the body control module. A second signal is issued from a second set of remote fobs in a second time slot in response to the interrogation signal from the body control module. The second time slot differs from the first time slot. A first remote fob is authenticated when the first signal is received by the body control module in a free and clear state. The second remote fob is authenticated when the second signal is received by the body control module in the free and clear state. If neither the first nor second signals are received in the free and clear state, the remote fobs are re-interrogated by the body control module.

  • Patent number: 10218528
    Abstract: A node forms a network by scanning for an existing network. If an existing network is not found, the node operates as a network controller node of the first network and admits at least one client node to the first network. As a network controller node, the node designates one of the client nodes as a scout node. The scout node removes itself from the first network and scans for a second network. If the scout node does not return to the first network after a predetermined time, it is assumed that the scout node has found a second network. The network controller node of the first network then designates the remaining client nodes as scout nodes, and then joins the second network as a client node. Therefore, multiple networks are avoided.

  • Patent number: 9526111
    Abstract: Methods, apparatuses, systems, and devices are described for wireless communication in an unlicensed spectrum. In one method, a clear-to-send (CTS) signal may be employed to manage or otherwise limit potential interference for communications in the unlicensed spectrum. For example, communications using long term evolution (LTE) may employ an unlicensed spectrum, particularly for small cell deployment. In such case, the LTE communications may be protected from interference due to communications by other networks, such as WiFi, using the unlicensed spectrum.

  • Patent number: 9485324
    Abstract: A broker may be used as an intermediary to exchange messages between producers and consumers. The broker may store and dispatch messages from a physical queue stored in a persistent memory. More specifically, the broker may enqueue messages to the physical queue that are received from producers and may dispatch messages from the physical queue to interested consumers. The broker may further utilize one or more logical queues stored in transient memory to track the status of the messages stored in persistent memory. As messages are dispatched to and acknowledged by interested consumers, the broker deletes acknowledged messages from the physical queue. The messages deleted are those preceding a physical ACKlevel pointer that specifies the first non-acknowledged message in the physical queue. The physical ACKlevel pointer is advanced in the physical queue based on the relative position of corresponding logical ACKlevel pointers maintained by the logical queues.
