Patents by Inventor James Roger Hargrave

James Roger Hargrave has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9912446
    Abstract: In a zigbee network, reliable communications are provided by maintaining messages transmitted from a device in a message queue in the device. If no successful acknowledgement is received for a transmitted message, the message is re-transmitted when the message queue executes. Messages are deleted from the queue when the message is successfully transmitted or when a maximum number of re-tries has been exhausted.

  • Patent number: 9749774
    Abstract: In order to minimize traffic on a Zigbee network, a gateway of the Zigbee network represents end devices in communications with peripheral networks. The gateway receives messages, such as status request messages, from the peripheral network intended for an end device on the Zigbee network. The Zigbee network generates a response message by retrieving stored data for the end device instead of communicating the received message to the end device.

  • Patent number: 9036527
    Abstract: An end device on a Zigbee network exits a power saving mode and transmits a wake notification message to the network. The network retrieves a cached status flag indicating whether the end device is defined on the Zigbee network and transmits the status flag to the end device. If the end device is undefined on the Zigbee network, the end device attempts to re-join the network. During the power saving mode, the network can cache messages intended for the end device and transmit the messages to the end device when the device exits the power saving mode.

  • Publication number: 20140340043
    Abstract: Disclosed are an apparatus and method of monitoring and charging a battery based on predefined criteria. One example method may include identifying an electronic device use event comprising at least one of an amount of time and an amount of battery charge used to perform the use event, and storing the electronic device use event in memory. The method may also include retrieving the electronic device use event from memory responsive to a battery charge management operation, and applying the electronic device use event to the battery charge management operation.

  • Publication number: 20140340051
    Abstract: Disclosed are an apparatus and method of monitoring and charging a battery based on predefined criteria. One example method may include identifying an event entry stored in an event application, estimating a time duration associated with the event, calculating an amount of battery charge required to satisfy the event being conducted on an electronic device, and charging a battery of the electronic device to a charge level corresponding to the calculated amount of battery charge.
