    摘要: An acoustic ceiling tile (200) operating as a capacitive power transfer sys tem comprises a first layer (231) comprising a non-conductive material; at least a pair of receiver electrodes (220, 221) of the capacitive power transfer system configured on a first side of the first layer; a foam layer (240) having a side substantially covered with the first layer; and a load (210) connected to an inductor (212) and to the pair of receiver electrodes, wherein the load and the inductor are configured in a chamber formed between the first layer and the foam layer, wherein a power signal generated by a power driver is wirelessly transferred from a pair of transmitter electrodes to the pair of receiver electrodes (220, 221)to power the load when a frequency of the power signal substantially matches a series-resonance frequency of the inductor and a capacitive impedance created between the pair of receiver electrodes and the pair of transmitter electrodes.

    摘要: A light emitting device comprising a first common electrode (11; 21), a structured conducting layer (12; 22), forming a set of electrode pads (14; 24a, 24b) electrically isolated from each other, a dielectric layer (13; 23), interposed between the first common electrode layer (11; 21) and the structured conducting layer (12; 22), a second common electrode (15; 30), and a plurality of light emitting elements (16; 20a, 20b), each light emitting element being electrically connected between one of the electrode pads (14; 24a, 24b) and the second common electrode (15; 30), so as to be connected in series with a capacitor (18; 31) comprising one of the electrode pads (14; 24a, 24b), the dielectric layer (13; 23), and the first common electrode (11; 21). When an alternating voltage is applied between the first and second common electrodes, the light emitting elements will be powered through a capacitive coupling, also providing current limitation. During operation of the light emitting device, a shorts circuit failure in one light emitting element will affect only light emitting elements connected to the same capacitor. Further, the short circuit current will be limited by this capacitor.
