  • Publication number: 20190140586
    Abstract: A double glass module, including a front panel glass (10), a first adhesive film (20), a solar cell pack group (30), a second adhesive film (40), aluminum foil (50), a third adhesive film (60) and a rear panel glass (70) successively stacked. The aluminum foil is added in front of the rear panel glass of a double glass module, and since the aluminum foil has a high light reflectivity, the reflection effect for transmitted light energy is improved, so that the power of the double glass module is significantly enhanced. Meanwhile, since the aluminum foil has a better heat conductivity, the heat generated by the solar cell pack group can be conducted and dissipated in time, so that the temperature of the double glass module is reduced in time, thereby reducing a temperature coefficient impact factor, and prolonging a daily mean efficient power output time of the double glass module.

  • Patent number: 10063292
    Abstract: Methods, devices, and computer-readable media for wireless communication may involve techniques for managing multi-user (MU) operation when a device in a wireless network has coexisting radios. Such techniques may involve identifying a change in a multiple radio access technology (RAT) coexistence status of a first device, e.g., a change between a coexistence status that is not disruptive to MU communications and one that is disruptive. For a device communicating with a network using Wi-Fi, the change in the multiple RAT coexistence status may indicate a change between inactive Bluetooth (BT) communications and active BT communications concurrent with Wi-Fi communications. Based at least in part on the identified change in the multiple RAT coexistence status, a MU communications operation at a second device may be adjusted, for example, by disabling MU communication between the first and second devices over a first RAT when the first device changes to a coexistence status that may disrupt MU communications.
