  • Publication number: 20230292105
    Abstract: A wireless device system can include lighting devices, sensing devices, and other wireless devices in a wireless mesh local area network. The devices are configured for rapid provisioning with provisioned site network data by using a process in which each device stores data for a default provisioning network, and a provisioning device, for example a smart phone or other mobile device, is used to wirelessly connect with at least one of the devices in the default provisioning network, enabling distant wireless devices to be reached by relay of messages in the default provisioning network. Devices can be individually provided a new network address, for example, from the provisioned site network data, and all devices are provided remaining data from the provisioned site network data using the mesh network broadcast feature, thus provisioning and switching devices near simultaneously from the default provisioning network to the provisioned site network.

  • Patent number: 8760043
    Abstract: Disclosed is an LED-based bulb-type lamp, including a cooling structure and a plurality of LEDs thermally connected to the cooling structure. The lamp includes at least three separate LED arrays oriented substantially parallel to its central longitudinal axis, such that the LEDs are interspersed among a plurality of light-transmission sub-areas of the LED-based lamp. One or more portions of the cooling structure of the lamp extend to its outer surface, as assembled, such that light-transmissive and heat-dissipating areas are spread over the outer surface, for example, in an alternating manner.

  • Publication number: 20100310926
    Abstract: A battery cell of a cylindrical lithium ion battery includes an anode plate and a cathode plate wounded together with an insulating separator disposed between the anode plate and the cathode plate. The anode plate includes an anode current collector and an anode film formed on the anode current collector. The anode current collector is formed with an anode exposed portion without the anode film formed thereon. The anode exposed portion is soldered with a number of anode terminals. The cathode plate includes a cathode current collector and a cathode film formed on the cathode current collector. The cathode current collector is provided with a cathode exposed portion without the cathode film formed thereon. The cathode exposed portion is soldered with a number of cathode terminals. The anode terminals and the cathode terminals are disposed at two opposite sides of the battery cell.
