Abstract: A BLUETOOTH Low Energy (BLE) device includes a BLUETOOTH transceiver, a memory storing a computer program, and a processor configured to execute the computer program. The computer program is configured to select a primary advertising channel as a target channel for transmission of a BLE advertising packet belonging to a BLE advertising event, and listen to the selected channel for a channel assessment time. Listening to the selected channel includes determining whether the selected channel is busy or idle. The computer program is further configured to transmit the BLE advertising packet on the selected channel when it is determined that the selected channel is idle during the channel assessment time.

Abstract: Methods and apparatuses are provided for recovering data transmitted to a terminal. A processor of the terminal selects a plurality of candidate frames expected to include the data from a memory of the terminal. Each of the plurality of candidate frames is received by the terminal and includes one or more errors. The processor compares corresponding values, for each of a plurality of bit sets, in the plurality of candidate frames. Specified fields of the plurality of candidate frames are excluded from comparison. The processor recovers the data based on the comparison.

Abstract: A transmitter for transferring a data stream to multiple receivers, the transmitter being configured to sample a first portion of the data stream to form a first sample dataset, encode the first sample set to form a first encoded dataset and transmit the first encoded dataset to a first one of the receivers; sample a second portion of the data stream to form a second sample dataset, encode the second sample set to form a second encoded dataset and transmit the second encoded dataset to a second one of the receivers; and to perform at least part of the step of sampling the second portion of the datastream while the first sample dataset is being encoded or the first encoded dataset is being transmitted.

Abstract: A directional display system includes a directional display device for displaying first visual content in a first direction, wherein the first direction is variable; and a processing system configured to establish a wireless link with a first wireless device positioned with a viewer for the first visual content, determine the direction of the first wireless device relative to the display device utilising the wireless link, and control the display device such that the first direction is defined at least in part by the direction of the first wireless device.
