Latest Patents

One of Walker's notable inventions is the "Blood Pressure Cuff Calibration System." This apparatus is designed to measure the pressure-transmitting characteristics of a blood pressure cuff in terms of delivered cuff pressure. It consists of a flexible cylindrical supporting tube filled with a non-compressible liquid, connected to a pressure transducer. The cuff is wrapped around the tube, and a rigid cylindrical tube covers the exposed area to prevent bulging when cuff pressure is applied. The cuff is pressurized while simultaneously recording its pressure and the transducer-detected pressure. The resulting X-Y curve is then compared with one taken of the supporting tube alone.

Another significant invention is the "Scanning Flow Indicator for Rotameters." This flow indicating attachment is designed for a transparent rotameter column containing a visible float that moves according to the rate of fluid flow. It features a reciprocating scanner that moves parallel to the column within the flow rate range, coupled to a potentiometer that forms a synchronous analog scanning signal for recording. The scanner includes a photoelectric float-sensing assembly with a photocell connected to the analog scanning signal circuit. When the sensing assembly is shaded by the rotameter float, it produces an abrupt dip in the recorded signal, providing a clear indication of the float's position.
