摘要： A sensor system for measuring physical properties of paper. The paper property sensor system includes a surface and a diaphragm (202) opposed to each other. The small diaphragm includes a first pair (A1, A2) and a second pair (B1, B2) p-type piezoresistors. Each piezoresistor (A1, A2) of the first pair is located perpendicular to and very close to one of the long edges (Fig. 5) of the diaphragm (202). Each piezoresistor (B1, B2) of the second pair is located between and parallel to first pair (A1, A2) of piezoresistors, and away from the short edges of the diaphragm (202). Balancing the first pair of piezoresistors against the second pair in a first Wheatstone bridge (Fig. 7) produces a voltage generated proportional to the thickness of a sheet, while balancing the piezoresistors of the first pair against one another of the piezoresistors of the second pair produces a voltage representative of the coefficient of friction of the sheet.

摘要： A system (140) for measuring the mass of a sheet (150) of material including an actuator (141), a position sensing system (42), and a tactile sensor system (200). The actuator (141) imparts a known force to the sheet (150), moving it through to the position sensing system (142), which measures the sheet velocity at various points. Afterward, the sheet (150) moves through the tactile sensor system (200), which determines the coefficient of friction of the sheet. Given these quantities, a controller can determine the mass of the sheet (150), which can be used alter the performance of paper handling devices in a reproductive machine. A second embodiment (Fig. 6) of the mass measuring system includes an actuator, a position sensing system, and a subsystem for eliminating friction. The actuator applies a force to a sheet to move it into and through the subsystem. The position sensing system incorporated in the subsystem senses the acceleration of the sheet. Given this quantity, a controller can determine the mass of the sheet.
