  • Patent number: 12265166
    Abstract: The invention discloses a method for acoustic indoor positioning based on CDMA, which comprises: generating a BPSK signal; The BPSK signal was detected, the collected signal was de-carrierized and low-pass filtered, and then the data was down-sampled to the design code rate, and then the coarse position of the identification code was determined by the prefix code. Finally, the data with the same length as the identification code was intercepted from the data for matching filtering through the coarse position. Four base stations were designed in each area to obtain three TDOA observations generated by four TOA information, and the terminal position could be obtained through the three TDOA observations. Different areas are distinguished by different identification codes to achieve wide area coverage. The invention provides an effective means for accurate positioning in an indoor environment.

  • Patent number: 12246347
    Abstract: An ultrasound system has a set of CMUT transducer devices and drive electronics for operating a selected device of the set. The drive electronics is shared between all devices of the set. Selection is made by using a set of switches (178), with a respective switch between a DC bias output (166) of the drive electronics and an associated input (160) of each device. This provides a simple way to provide a selection function between the drive electronics and multiple ultrasound devices. In this way, the number of devices may be scale up, to cover a larger area, but without scaling the cost of the system by the same degree.
