Abstract:
In accordance with an example embodiment of the present invention, a first bit sequence of a first length is assigned to a first group of signaling bits. Further, a second bit sequence of a second length is assigned to a second group of signaling bits. The first bit sequence is scrambled with a first scrambling sequence, and the second bit sequence is scrambled with a second scrambling sequence different from the first scrambling sequence. A first and a second orthogonal frequency-division multiplexing (OFDM) symbol are assigned to the first and the second scrambled bit sequences respectively, and the first and second orthogonal frequency-division multiplexing (OFDM) symbols are transmitted as synchronization symbols of a data frame. Further, a corresponding method for receiving the data frame, and apparatuses for transmission and reception are disclosed.
Abstract:
The invention relates to a method that comprises receiving wireless energy from a wireless energy transmitter device; determining a power level value of the received wireless energy; manipulating value of the determined power level to obtain a manipulated power level value; and sending the manipulated power level value to the wireless energy transmitter device so that a FOD does not prevent the power transfer from the wireless energy transmitter device. The invention further relates to an apparatus, a device and a computer program product for performing the method.

Abstract:
Various embodiments are disclosed relating to techniques for exchanging data and/or power between a plurality of devices. In accordance with an example embodiment of the present invention, a device may receive power via a voltage terminal of an interface. The interface may also comprise at least one configuration channel terminal. The device may determine to terminate power reception via the voltage terminal causing a current through the configuration channel terminal to decrease below a threshold, and the device may determine to supply power to the voltage terminal.
Abstract:
A method for analyzing a presence of objects within a space provided with a capturing system comprising a plurality of camera devices and a playback system for reproducing audio and/or visual signals in the space, the method comprising obtaining a first 3D volumetric representation of a scene within the space, generated on the basis of input streams of at least a first and a second camera device, said first 3D volumetric representation showing at least one object within the scene; sending probe signals to a processing unit; controlling the processing unit to reproduce, using the playback system, one or more audio and/or visual signals on the basis of the probe signals into the space; controlling the processing unit to capture a second 3D volumetric representation of the scene including reproductions of the one or more audio and/or visual signals within the space; and analyzing the reproductions of the one or more audio and/or visual signals captured within the first space whether they correspond to a presumed location of the at least one object shown in the first 3D volumetric representation.
