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.

Abstract: The present invention is concerned with a wireless transceiver for implantable medical devices, and has a first coil winding wound around its coil axis in a first direction, at least one second coil winding wound around its coil axis in a second direction non-parallel with the first direction, and at least one circuit board having at least one control circuit; wherein the first and the second coil windings are electrically connected to the control circuit of the circuit board respectively.

Abstract: A zipper includes two straps each having a series of teeth secured on one side of the two straps. A core is embedded into each of the two series of teeth and a suture is sewn into each of the series of teeth and the strap to hold the series of teeth and the core in place on the strap, wherein the two series of teeth are made of transparent material and selectively engaged to each other such that the user can see the color of the core through the transparent teeth for promoting the vision effect of the zipper. The sutures is previously dyed and divided into multiple color sections each having a single color such that the suture forms multiple continual color portions on the zipper after sewing on the teeth for securing the series of teeth on each of the straps.
