    • The present invention is directed to a system that enables the simultaneous remote monitoring of a plurality of infants' skin temperatures. The system comprises an electronic circuit that combines the functions of sensoring and multiple-channel transmitting, a pre-deployment temperature bath for calibration of the temperature sensor(s), and a receiving and reporting station for centralized monitoring the infants' skin temperatures. The present invention is further directed to a temperature sensor that measures the temperature and transmits the data in multiple channels to a remote receiver. In one embodiment, the temperature sensor comprises a ring oscillator, having a plurality of odd number of inverters, and the ring oscillator is capable of utilizing less than all of the inverters in the ring to modulate the frequency of the signal. In another embodiment, the temperature sensor comprises one inverter and a plurality of delay elements and sensor transmits phase shifted signals to modulate the signals. A signal processing method is also disclosed.
    • 本发明涉及能够同时远程监测多个婴儿皮肤温度的系统。 该系统包括组合传感和多通道传输功能的电子电路,用于校准温度传感器的预部署温度浴,以及用于集中监控婴儿皮肤温度的接收和报告站。 本发明还涉及一种温度传感器,其测量温度并将多个通道中的数据传输到远程接收器。 在一个实施例中,温度传感器包括具有多个奇数个反相器的环形振荡器,并且环形振荡器能够利用小于环中的全部反相器来调制信号的频率。 在另一个实施例中,温度传感器包括一个逆变器,并且多个延迟元件和传感器传输相移信号以调制信号。 还公开了一种信号处理方法。
