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 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:
A battery management apparatus and method for use in an electrical vehicle has a plurality of individual batteries 34 provided within a battery pack 10. The battery pack is coupled to power vehicle traction 12 and a plurality of individually connectable vehicle appliances 18-26. A monitor keeps track of charge state by means of a battery monitor 44 on each battery relaying instant current to a processor 27. In a first embodiment, a charge allocation profile for the whole battery pack 10 is used where different appliances 18-26 have different amounts of charge capacity allocated to them and are disconnected when discharge exceeds their allocation and are reconnected during charging when their charge is again found. In a second embodiment, individual batteries 34 and appliances 18-26 are connected within a network configuration allowing anything to be connected to anything else. Battery 10 segments can be created, each having one or more allocated individual batteries and each segment connected to selectable services 12 18-26 within the electric vehicle. Segmentation patterns can be changed. A segment charge allocation profile can be used within each segment in much the same way that the charge allocation profile can be used and changed for the first embodiment. Progressive charging and discharging of the battery is the end result.
Abstract:
Un sistema que tiene una cadena de aparatos para recibir y enviar señales de energía y datos, la cadena de aparatos comprende: una unidad (5A, 5B, 5C) primaria, operable para recibir una señal de datos y que comprende un modulador operable para generar y transmitir una señal modulada con la señal de datos, dicha señal es una señal de radio o de inducción magnética, o ambas; y una o más unidades (5) secundarias en la cadena, en el que cada una de las una o más unidades (5) secundarias comprende: primeros medios (10) de antena, operables para recibir una señal de entrada modulada para incluir la señal de datos; medios operables para recibir y decodificar la señal de entrada para proporcionar una señal de datos decodificada; medios operables para convertir la señal de entrada en energía eléctrica para alimentar cada una de las una o más unidades (5) secundarias; medios para generar una señal de salida modulada con la señal de datos decodificada; y segundos medios (32) de antena operables para transmitir la señal de salida, caracterizados porque una o más unidades (5) secundarias son se pueden concatenar en la cadena con la unidad (5A, 5B, 5C) primaria que forma el inicio de la cadena.
