Abstract: Systems and techniques are provided for a spiral light antenna. An antenna element may include a first curved element disposed orthogonally to a second curved element. The first curved element and the second curved element may be connected at a connection point at a center of the first curved element and a center of the second curved element. The antenna element may have rotational symmetry and origin symmetry though the connection point but not linear symmetry. The first curved element may be longer than the second curved element. A feed may be connected to the antenna element at the connection point perpendicular to the plane of the antenna element. The first curved element may be inductive, and the second curved element may be capacitive. The antenna element may be disposed at the front of a light bulb and the feed may extend towards the back of the light bulb.

Abstract: Disclosed is a simulcast approach to broadcasting a message from each device, or node, of a network. A source device, such as a wall switch, may broadcast a message that may be received by a plurality of devices, such as light bulbs, in a network. Each of the plurality of devices may receive the message at substantially the same time. In response to the message, the receiving devices may determine if the message is to be retransmitted. If the message is to be retransmitted, it may generate a modified message. Each of the plurality of devices may transmit the modified message substantially simultaneously. To maintain timing to the source device between the devices in the network, the message may be configured to facilitate synchronization of the clocks to a timing signal in the message.

Abstract: Disclosed are methods in which a source device that may multicast a message to a plurality of destination devices. The source device may receive an acknowledgement from less than all of the plurality of destination devices. Each acknowledgement may include an indication of the destination device from which the acknowledgement is received. A destination device may process the multicast message and generate an acknowledgement in response. In response to a time period subsequent to transmission of the multicast message, the source device may generate an updated message that indicates an acknowledgement status of each destination device associated with the group identifier from which an acknowledgement has been received.

Abstract translation: 公开了可以将消息多播到多个目的地设备的源设备的方法。 源设备可以从小于所有多个目的设备的接收端收到确认。 每个确认可以包括从其接收到确认的目的地设备的指示。 目的地设备可以处理多播消息并响应于生成确认。 响应于多播消息传输之后的时间段，源设备可以生成指示与已经从其接收到确认的组标识符相关联的每个目的地设备的确认状态的更新消息。
