Abstract: A single-barometer device, a method for fall detection and a system are provided. The single-barometer device worn on a user is used to measure multiple barometric values continuously by a barometer inside the device. The barometric values are stored in a memory of the single-barometer device. When a current barometric value is produced, the current barometric value is compared with a previous barometric value retrieved from the memory. A barometric difference can be obtained. The barometric difference is then compared with a threshold, and a comparison result is used to determine whether or not a fall event is present. The fall event is confirmed if the barometric difference is larger than the threshold. Further, an acceleration change obtained by an accelerometer inside the single-barometer device can be used to reconfirm the fall event.

Abstract: Apparatus and method for packet redundancy and recovery are disclosed. In a transmitter, parity packets are generated by executing exclusive OR between the corresponding data packets, and are transmitted along with the data packets to a receiver. In the receiver, lost data packets are found out and are recovered by executing exclusive OR between the corresponding data packets and the corresponding parity packets. This invention enhances the reliability of streaming data transmission using loss-recovery packets. Data packets are grouped and transmitted with redundant packets to allow the receiver to recover a lost packet within the group. This will minimize the need and therefore the time and delay to request a retransmission of the damaged or lost packets.

Abstract: A structure of ribbon type planar speaker is provided, which includes a composite diaphragm with a flexible edge fixed on a fixed end; a first magnet and a second magnet, respectively disposed above and below the composite diaphragm, and respectively fixed on an upper frame and a lower frame, wherein both frames have openings; and a second lower frame, disposed below the lower frame, wherein an air damping absorption layer is disposed between the lower frame and the second lower frame. The air damping absorption layer enhances air damping and thus limits irregular vibration between the diaphragm and the pushed air. Therefore, when the diaphragm of the ribbon type planar speaker is in vibration, the effective vibration range performs uniform synchronous vibration, thus making the frequency response range broader and smoother.
