    • A method for sonic acoustic beacon processing. The method may include constantly operating a microphone and a chip, even when an application processor is asleep; receiving by the microphone, while the application processor is asleep, an acoustic beacon; converting by the acoustic beacon to electrical signals representative of the acoustic beacon; receiving by the chip the electrical signals representative of the acoustic beacon; searching, by the chip and in the electrical signals representative of the acoustic beacon for a predefined preamble; when detecting the predefined preamble then decoding, by the chip, electrical signals representative of a rest of the acoustic beacon to provide digital data, and determining by the chip whether to awake the application processor; when determining to awake the application processor then participating, by the chip, in an awakening of the application processor; and sending, by the chip, the digital data to the application processor, after the awakening of the application processor.

    • A blood oxygen saturation level (SpO2) measurement subunit employed in a wireless transceiver unit connected to a medical monitor unit. An illumination emulator is used for emulating the characteristics of an illumination source of a pulse oximeter. The emulator utilities at least part of the energy coming from the SpO2 socket of the medical monitor. Energy originally intended to energize one illumination source of the pulse oximeter, energizes the power supply circuitry. A processor is employed for processing information about pulsing arterial blood of a patient received from a patient companion assembly (PCA). A digital to analogue converter is used for converting the PCA, to analogue signal. A low pass filter (LPF), filtering the signal to form a pulsative voltage signal represents the pulsing arterial blood of the patient, and is sent to the SpO2 socket of the medical monitor for displaying and further processing.
    • 在与医疗监视器单元连接的无线收发器单元中采用的血氧饱和度(SpO2)测量子单元。 照明仿真器用于仿真脉搏血氧计的照明源的特性。 仿真器至少部分来自医疗监护仪的SpO2插座的能量。 最初旨在激励脉搏血氧计的一个照明源的能量,激励电源电路。 处理器用于处理从患者伴侣组件(PCA)接收的患者的脉动动脉血的信息。 数模转换器用于将PCA转换为模拟信号。 低通滤波器(LPF),对信号进行滤波以形成脉动电压信号,代表患者的脉动动脉血,并被传送到医疗监护仪的SpO2插座进行显示和进一步处理。
