Embodiments of the present disclosure provide sensors inside an In-Circuit Tester (ICT) that measure stress on a Printed Circuit Board (PCB) every time the ICT runs through a manufacturing process. This ICT can comprise an Internet of Things (IoT) device which can measure, monitor, record, and show stress data that is being exerted by ICTs on the mounted PCB in real-time during tests thereby providing technicians an ability to oversee failures based on historical data that the IoT device provides.

MEMS force sensors for providing temperature coefficient of offset (TCO) compensation are described herein. An example MEMS force sensor can include a TCO compensation layer to minimize the TCO of the force sensor. The bottom side of the force sensor can be electrically and mechanically mounted on a package substrate while the TCO compensation layer is disposed on the top side of the sensor. It is shown the TCO can be reduced to zero with the appropriate combination of Young's modulus, thickness, and/or thermal coefficient of expansion (TCE) of the TCO compensation layer.

An input device is described which comprises a touch-sensitive surface and a force sensor, wherein the force sensor is adapted to detect a force applied to the touch-sensitive surface. The input device further comprises a vibration sensor and a control unit, wherein the control unit is coupled with the force sensor, the touch-sensitive surface and the vibration sensor. The control unit is adapted to validate a force detected by the force sensor as an input in dependence on a touch of the touch-sensitive surface and in dependence on a vibration detected by the vibration sensor. There is further described a motor vehicle which comprises such an input device. A method of detecting an input at an input device is further described.

A force sensor diagnostic device that diagnoses a force sensor provided in a robot, the force sensor disposed near an installation surface on which the robot is installed and detecting a force and a moment applied to the robot from an outside. The device includes a calculation unit that calculates a theoretical value of the force and a theoretical value of the moment detected by the force sensor, a determination unit that determines whether the force sensor is distorted by comparing an actually measured value of the force and an actually measured value of the moment detected by the force sensor with the theoretical values of the force and the moment, and a notification unit that notifies a determination result from the determination unit.

A contact determination device includes a sensor measuring a contact degree of a body to be detected with an object, a contact determination unit determining whether the body to be detected is in contact with the object, based on a reference value, and a correction unit correcting the reference value, in which a cumulative value is obtained by accumulating a fluctuation amount of the detection value from a contact start time of the body to be detected with the object during a period in which the body to be detected is in contact with the object, and when the detection value increases as the contact degree increases, the correction unit corrects the reference value, based on a maximum value of the cumulative value, or when the detection value decreases as the contact degree increases, the correction unit corrects the reference value, based on a minimum value of the cumulative value.
