Classification: CPC A | IPC A

Claim 0:
1. A pressure-sensing device comprising:
a device frame comprising:
a base surface configured to rest on an external supporting structure that is separate from the pressure-sensing device; and
a frame attachment region located opposite to the base surface such that the frame attachment region is raised from the external supporting structure when the base surface is resting on the external supporting structure;

a flexible membrane including a membrane attachment region attached to the frame attachment region, wherein the flexible membrane protrudes above the device frame and is configured to conform to a user's perineum region when the user is seated on the flexible membrane, and wherein the device frame and the flexible membrane at least partially enclose a pressure chamber including an air mass between the device frame and the flexible membrane;
a pressure sensor at least partially included within the pressure chamber and in contact with the air mass, the pressure sensor configured to generate a pressure signal indicating air pressure of the air mass in the pressure chamber; and
device electronics configured to:
determine the air pressure in the pressure chamber based on the pressure signal;
determine a pressure reference value based on the determined air pressure in the pressure chamber; and
detect a muscle contraction event based on a change in the determined air pressure in the pressure chamber relative to the pressure reference value.
