Abstract: A baby stroller includes a base and a suspension unit is connected to the base. The suspension unit has a movable rod which is movably connected to the suspension unit. A support frame is connected to the distal end of the movable rod and a seat or a bed is connected to the support frame. The suspension unit absorbs shocks and vibration transferred from the road. The distance between the seat or the bed and the base is adjusted by the movement of the movable rod. The seat or the bed can be rotated to face the user or to face front.

Abstract: An apparatus and method for pulse detection based on blood pressure measuring stage is disclosed. Both monitoring of blood pressure and blood vessel pulse are integrated and applied to an apparatus. With the components of the blood pressure monitor, such as an inflatable cuff an air pump and a variable flow valve, with a unique sequential pressure control of reduction and regulation of pressure, not only can blood pressure parameters but also pulse signals under various pressures be measured to provide a complete analysis of blood artery/vessel conditions.

Abstract: An apparatus is provided for evaluating cardiovascular functions. The apparatus combines the principles of measuring pressure and pulse signals, and monitors blood pressure, pulse wave velocity and electrocardiogram (ECG) signals simultaneously. An inflatable cuff measures blood pressure and pulse wave velocity. The apparatus also calculates systolic pressure, diastolic pressure, mean arterial pressure and other parameters related to blood pressure. The apparatus not only calculates vascular Stiffness Index (SI), vascular Reflection Index (RI) and other arterial related parameters but also Pulse Wave Velocity (PWV), heartbeat, QRS interval, ST segment, and other ECG parameters.
