Abstract:
First, light-sensing devices (1) comprise sensors (11) for sensing light (3) originating from second, light-generating devices (2) and for generating sensing results and comprise generators (12) for generating information (4) in response to the sensing results and comprise transmitters (13) for wirelessly transmitting the information (4) to the second devices (2). The second devices (2) comprise lightsources (21) for generating the light (3) and comprise drivers (22) for driving the light sources (21) and comprise receivers (23) for wirelessly receiving the information (4) for adapting the driving of the light sources (21). The first devices (1) may be self-powered devices and may comprise converters (31) for converting the light (3) for feeding the first devices (1). The light sources (21) may comprise one or more light emitting diodes.
Abstract:
An antenna module more particularly for the high-frequency and microwave range is described which can be operated as a wideband antenna in various frequency bands. For this purpose the antenna module is particularly suitable in that it has an antenna (10) and an HF line (20) to connect the antenna (10) to associated transmit and/or receive stages, while at least parts or sections (21, 22) of the HF line (20) have a mismatch in the form of an impedance deviating from that of the antenna (10). The invention also relates to a telecommunications device having such an antenna module.
Abstract:
The proposed invention application describes a novel configuration of an extremely small self-locking switching component, based on micro- electromechanical systems (MEMS) technology. Conventional MEMS switches need a continual control signal in order to obtain the wanted active (switching) state. The proposed invention needs only a short control signal (non-locking key) such as e.g. a pulse in order to switch the component on and/or off. RF-noise (ripples) on the de-control signal or bouncing effects can be neglected according to the proposed extension of the MEMS devices. This contributes to an easier and especially more robust design of electronic circuitries and allows for enhanced functionalities.
