Abstract: A signaling of at least one characteristic for layers of a multi-layered video signal such as, for example, for each layer the indication of dependent layers to which the respective layer directly relates via inter-layer prediction, or the signaling of the afore-mentioned second inter-dependency syntax structure, is described. A maximum syntax element is signaled within the multi-layered video signal to indicate a maximally used value of an extension layer-ID field of the packets of the multi-layered video signal, the scope of the maximum syntax element being, for example, a predetermined portion of the multi-layered video signal extending, for example, across several portions of the multi-layered video signal. Accordingly, it is feasible for devices such as decoders or network elements receiving the multi-layered video signal to gain, for a relatively large predetermined portion of the multi-layered video signal, knowledge about the actually consumed portion of the possible domain of possible values.

Abstract: A load control system may include one or more wireless control devices that may be associated via a programming device. An identifier for a first wireless control device may be determined in response to an actuation of a button on the first wireless control device. An association between the first wireless control device and a second wireless control device may be defined at the programming device.

Abstract: The present invention relates to systems and methods for measuring signal strength emitted by a wireless portable device to determine the location of the wireless portable device. The wireless portable device may be located within a designated geographical location, premise or facility. The measurement involves two levels of transmissions. A first level involves a user's wireless portable device receiving signals from a plurality of beacons in the vicinity. The second level involves transmission of repeater signals from a mesh network. The payload of these signals, which may include a duress signal, includes the strength of the received beacon signals, so that when the duress signal is received by a controller, the signal strengths of both levels/types of transmissions can be determined. This two-level collection of signals is then processed by a neural network which have been previously trained to classify the signal collections into precise locations.
