Abstract: A sensor for monitoring external loads acting on a pin assembly includes a pin having an axial interior bore defined therein and having a length defined from a first end to an opposed second end thereof. A core pin is mounted axially within the interior bore of the pin spaced radially inwardly from the interior bore for relative displacement with respect to the pin. A capacitor is provided having an inner capacitor plate mounted to the core pin, and an outer capacitor plate mounted to the pin, such that relative displacement of the core and the pin due to external loading on the pin results in relative displacement of the inner and outer capacitor plates. The capacitor is configured and adapted to be connected to an electrical circuit to produce signals indicative of external loading on the pin based on relative displacement of the inner and outer capacitor plates.

Abstract: A flexible apparatus and method to enhance capacitive force sensing is disclosed. In one embodiment, a force measuring device includes a sensor capacitor having a fixed surface and a moveable surface substantially parallel to the fixed surface, at least one spring assembly (e.g., may deflect longitudinally and/or perpendicularly to a direction of the force) positioned between the fixed surface and the movable surface (e.g., the spring assembly may alter in height in response to a force applied perpendicular to the movable surface and to cause a change in the gap between the fixed surface and the movable surface), and a circuit to generate a measurement of the force based on an algorithm that considers a change in a capacitance of the sensor capacitor. A reference capacitor may adjust the measurement of the applied force based on one or more environmental conditions.

Abstract: A capacitance type sensor good in operability and less in erroneous operation is provided. Switches SW1 to SW4 are formed between a displacement electrode 40 and switch electrodes E11 to E14 kept at a predetermined potential and grounded switch electrodes E15 to E18. Switches SW 11 to SW 15 are connected to respective capacitance electrodes E1 to E5 that cooperate with the displacement electrode 40 to form capacitance elements. A decision circuit judges states of the switches SW1 to SW4. When at least one of the switches SW1 to SW4 is off, periodic signals are input only to the capacitance electrodes E1 to E4 corresponding to X- and Y-axial directions. When any of the switches SW1 to SW4 is on, a periodic signal is input only to the capacitance electrode E5 corresponding to a Z-axial direction.
