Smart Phone Scale

摘要

A weighing assembly (100,500,600) includes a portable computing device (“PCC”) (112) such as a smart phone, pad computer, laptop computer, or the like. The weighing assembly utilizes one or more features of the portable computing device in order to weigh an item, under control of a scale application program or “app” executable in the portable computing device. Some embodiments may utilize an internal barometric pressure sensor of the PCC. Other embodiments may utilize orientation or position sensors of the PCC for weighing an item. Other embodiments may utilize a compressible foot element (1004), all for weighing an item. Preferably, a user interface (114) of the PCC, such as a touch screen, may be used to interact with the scale application program for calibration and other functions.
