    Abstract: A mobile telephone device (10) comprises a microphone (20) and one or more spaced audio sensors (12) to sense the position and/or voice characteristics of one or more individual speakers (16). A mute control means (14) employs sound phase, and/or sound time of arrival, and/or sound loudness to create a map of the positions of individual speakers (16). The mute control means (14) identifies individual speaker (16) voice characteristics using one, the other or both of audio signal analysis of the sound of individual speaker's voices; and use of voice CODEC analysis results for each individual speaker. A call may involve no sound muting, may involve sound muting except for one individual speaker (16), or sound muting except for any one of a plurality of accepted individual speakers. A default individual speaker position immediately before and closest the microphone is provided. Positional tolerance for individual speakers of at least 5% to 10% is employed.

    Abstract: An apparatus can receive and transfer data and energy between adjacent apparatus in a chain. Each apparatus comprises an input antenna for receiving an input signal which is tuned and impedance matched for a receiver and demodulator in a control circuit. The demodulated signal is provided as input to a transmitter module to create an output signal. The input signal is then impedance transformed to generate a sufficient voltage to energize a power supply which charges a battery. The input signal and the output signal can be a radio signal, a magnetic induction signal, or a combined radio and magnetic induction signal. A controller in the control circuit monitors the condition of the battery and power supply and controls a switch operable to selectively power parts of the apparatus dependently upon their monitored condition.

    Abstract: A display screen 12 comprises at least an upper layer 26, 36 and a lower layer 28, 38, 50. The display screen 12 can be a touchscreen. One of the upper layer 26, 36 and lower layer 28, 38, 50 is provided as a photovoltaic layer and the other of the upper layer 26, 36 and the lower layer 28, 38, 50 is provided as a display layer. The upper layer 26, 36 can be a rigid or flexible layer, and the lower layer 28, 38, 50 can also be flexible or rigid. An intermediate layer 32, 44, 48, can be provided between the upper layer 26, 36 and the lower layer 28, 38, 50. The intermediate layer 32, 44, 48 can be rigid, flexible or compressible. Each photovoltaic layer comprises at least one solar panel 52 with each solar panel 52 comprising at least one solar cell 54. The photovoltaic layer is employed to charge a power supply battery 58. The photovoltaic layer can occupy the entire display screen 12, or only a proportion of the area of the display screen 12.
