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: 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: Techniques for controlling diversity beamforming antenna array is disclosed. One aspect of the techniques is to utilize low-power and low area circuits to achieve combining gains, mitigate the effects of multipath fading, provide spatial suppression and diversity gains to a single input receiver. The device is radiofrequency transparent yet provides antenna gain by selective three G and four G code acquisition and tracking of a desired downlink channel.

Abstract: A single-chip CMOS direct conversion transceiver includes an RF circuit, a transmitter having a synthesizer, a receiver having a baseband filter, and a demodulator. The synthesizer is coupled to the RF circuit. The baseband filter is coupled to the RF circuit and the synthesizer. The demodulator is coupled to the baseband filter. The RF circuit, the synthesizer, the baseband filter, and the demodulator are arranged and configured in CMOS devices and provide a complete interface between an antenna and a voiceband codec.
