Pressure-Sensing Devices

摘要

A pressure-sensing device includes a device frame, a flexible membrane, a pressure sensor, and device electronics. The device frame includes a base surface that rests on a supporting structure and a frame attachment region located opposite to the base surface such that the frame attachment region is raised from the supporting structure when the base surface is resting on the supporting structure. The device frame also includes a seating surface. The flexible membrane is attached to the frame attachment region such that the device frame and the flexible membrane enclose a pressure chamber. The seating surface extends outward around the flexible membrane and the flexible membrane protrudes above the seating surface. The pressure sensor is configured to generate a pressure signal. The device electronics are configured to determine the pressure in the pressure chamber based on the pressure signal.

1. A pressure-sensing device comprising:
a device frame comprising:
a base surface configured to rest on an external supporting structure;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; anda seating surface; a flexible membrane including a membrane attachment region attached to the frame attachment region, wherein the device frame and the flexible membrane at least partially enclose a pressure chamber between the device frame and the flexible membrane, and wherein the seating surface extends outward around the flexible membrane and the flexible membrane protrudes above the seating surface; a pressure sensor at least partially included within the pressure chamber, the pressure sensor configured to generate a pressure signal indicating a pressure in the pressure chamber; and device electronics in communication with the pressure sensor, the device electronics configured to determine the pressure in the pressure chamber based on the pressure signal.
