Abstract: A health care system including a cloud database, a physiological sensor and a processor is disclosed. The cloud database is configured to store a reference waveform and an abnormal data record. The physiological sensor is configured to detect a detected part of a body and to generate a detected physiological signal. The processor is electrically connected to the cloud database and retrieves the reference waveform from the cloud database. The processor is electrically connected to the physiological sensor to receive the detected physiological signal, converts the detected physiological signal into a physiological waveform, compares the physiological waveform with the reference waveform to determine a frequency error and a peak error therebetween, and generates a driving signal when the frequency error is not smaller than a frequency threshold and the peak error is not smaller than a peak threshold. Advantageously, the efficiency of health management can be improved.

Abstract: A control system for controlling an ultrasonic probe includes a module for assigning address parameters respectively to ultrasonic transducers of the probe according to a physical position order of the ultrasonic transducers, a module for arranging the address parameters in an activation sequence, and a module for generating activating signals each corresponding to a respective address parameter. Sequential two address parameters in the activation sequence correspond to two ultrasonic transducers that are non-sequential to each other in the physical position order. Each activating signal is transmitted to a respective ultrasonic transducer that is assigned with the address parameter to which the activating signal corresponds.

Abstract: Monitoring signals associated with operating parameters of an optical transceiver are ascertained by using a comparator arrangement external to a micro-controller unit. Monitoring signals associated with these operating parameter are provided as inputs to a discrete arrangement of comparators and then evaluated against a known reference voltage source. The reference source is swept across a known range of values, and when the output of the comparator changes state, the value of the reference input associated with this transition is defined as the value of the specific monitoring input signal and stored within the proper memory location within the microcontroller portion of the transceiver monitor circuit. The digital output signal of the comparator is applied as an input to the microcontroller, which recognizes this digital signal as defining the specific value of the reference signal to use and equate with the value of the monitored signal.
