  • Publication number: 20260194218
    Abstract: A solid-state lighting fixture assembly having a lighting fixture with a socket configured to receive a plug associated with one or more accessories to allow for easy in-field mounting of accessories, e.g., controls, onto installed lighting fixtures. The socket may be internally electrically connected to an auxiliary power output of a driver and/or to a battery power pack within the lighting fixture assembly, thereby providing direct-current voltage power for the accessory and, also, allowing for signal transmission to and from the accessory. Each accessory includes one or more sensors and communication components to provide the connected lighting fixture assembly with specific capabilities including, but not limited to, motion detection, ambient light level detection, ambient temperature measurement and wireless communications.

  • Patent number: 10014995
    Abstract: The present disclosure relates to the field of communication technology, and provides a data transmission method, a data reception and detection method, a base station and a UE on the basis of a non-orthogonal mode. Before the transmission of pieces of data on physical resources by the base station, a plurality of pieces of data is firstly mapped to the physical resources at an amount not greater than the number of the pieces of data, each piece of data in the plurality of pieces of data is mapped to at least one physical resource, and the number of the physical resources to which each piece of data is mapped is not completely the same. Then, the pieces of data on the physical resources are transmitted by the base station. According to the present disclosure, it is able to transmit more pieces of data through fewer physical resources, thereby to improve the data transmission capability for the communication system.
