Latest Patents

One of Jian Dai's latest patents is a method and system for acoustic indoor positioning based on CDMA. This invention discloses a method for acoustic indoor positioning that involves generating a BPSK signal. The BPSK signal is detected, and the collected signal is de-carrierized and low-pass filtered. The data is then down-sampled to the design code rate, allowing for the determination of the coarse position of the identification code through the prefix code. The invention also describes the design of four base stations in each area to obtain three TDOA observations generated by four TOA information, enabling accurate terminal positioning. This method provides an effective means for precise positioning in indoor environments.

Another notable patent is an alarm threshold setting suggestion method, system, and monitor. This method includes obtaining monitoring data of a patient and determining whether the current alarm threshold associated with a monitoring parameter needs adjustment. If an adjustment is necessary, the system generates threshold setting suggestion information based on the monitoring data and the current alarm threshold. This innovation not only prompts users to adjust the alarm threshold but also provides valuable information for reference, helping to alleviate alarm fatigue.
