Abstract: A heart rate detection apparatus includes a signal acquisition device for acquiring an intra-aural vibration wave signal and converting the intra-aural vibration wave signal into an intra-aural vibration electrical signal; and an arithmetic processing device for processing the intra-aural vibration electrical signal by computing to generate heart rate information. In the prior art, the heart rate detection apparatus cannot accurately and reliably detect the heart rate information due to the weak optical signal detected by a sensor. The heart rate detection apparatus acquires the intra-aural vibration wave signal to obtain the heart rate information, thus enabling the apparatus to accurately and reliably detect heart rate information.

Abstract: Disclosed is a message reminding method and device. The method includes the following steps: (1) receiving N reminder messages; (2) detecting current time and determining whether the P-th reminder time TP is reached; (3) sending the P-th reminder content information while detecting a response message within a first predetermined sending time: if the response message is received within the first predetermined sending time, proceeding to step (4); otherwise, stopping sending the P-th reminder content information and modifying the P-th reminder time TP; (4) determining whether the response message is a first or second response message: if the first response message, stopping sending the P-th reminder content information and cancelling the P-th reminder message; if the second response message, stopping sending the P-th reminder content information and changing the P-th reminder time TP to a delayed time T?P.

Abstract: A Magnetic Czochralski semiconductor wafer having opposing first and second sides arranged distant from one another in a first vertical direction is treated by implanting first particles into the semiconductor wafer via the second side to form crystal defects in the semiconductor wafer. The crystal defects have a maximum defect concentration at a first depth. The semiconductor wafer is heated in a first thermal process to form radiation induced donors. Implantation energy and dose are chosen such that the semiconductor wafer has, after the first thermal process, an n-doped semiconductor region arranged between the second side and first depth, and the n-doped semiconductor region has, in the first vertical direction, a local maximum of a net doping concentration between the first depth and second side and a local minimum of the net doping concentration between the first depth and first maximum.

Abstract: Disclosed is a fingerstall oximeter comprising an upper housing (11), a middle housing (12), a lower housing (13) and a detection unit. The upper housing (11), the middle housing (12) and the lower housing (13) are connected in turn. The lower housing (13) is made of silica gel, and a finger accommodating chamber (14) for accommodating a finger to be measured is formed between the opposed surfaces of the lower housing (13) and the middle housing (12). The fingerstall oximeter has high measurement accuracy and small volume, and is easy to disassemble and carry.

Abstract: There is provided a fingertip oximeter that has a plurality of display modes which are presented sequentially in a circulating way, allowing users to easily observe a measurement result from any of surrounding directions. The present invention makes users to be able to observe a measurement result of the fingertip oximeter from any of surrounding directions, without the need of bending his/her finger. Thus, any partial occlusion of the arterial blood capillary can be avoided, so that strength of the pulse will not decrease, and strength of the signal will not be affected. As a result, the precision of the measurement is improved.
