Abstract
Abstract There is disclosed a body parameter display device incorporated in a digital wrist watch for alternatively displaying time and a value representative of the body parameter. A pressure sensor incorporated in the device delivers an electrical output which is manipulated to deliver a signal proportional to the blood pressure sensing. In addition, the electrical pulses are manipulated to deliver a value representative of pulse rate. The pressure sensor also delivers an electrical output which is used to energize the watch and display mechanism and/or to charge a battery contained in the watch casing.
