Abstract: 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.

Abstract: A parallel guide of a force transmission device has movable and fixed parallel legs, and first and second parallel guiding elements. Thin-point flexional bearings connect the parallel legs to the parallel guiding elements. The movable parallel leg is guided by the parallel guiding element on the fixed parallel leg. A force transmission lever, arranged on the fixed parallel leg, has a lever bearing, and a first lever arm. The force transmission lever is pivotably mounted on the lever bearing and the first lever arm is connected to the movable parallel leg to transmit force. The force-transmitting connection is produced by a coupling element having at least one further thin-point flexional bearing, with at least one functional region of the force transmission device being formed monolithically. A functional region associates at least one bearing point with at least one of the parallel legs, the force transmission lever, and the coupling element.

Abstract: A system includes a sensor network comprising a network of optical sensors coupled to structural members of a structure loaded by vehicles or by an environmental event. A processor is operatively coupled to the sensor network. The processor is configured to receive the strain measurements from the network of optical sensors, calculate total strain energy using the received strain measurements, detect a heavy load on the structure in response to the total strain energy exceeding a total strain energy threshold developed for the structure, and determine whether the heavy load results from a superload vehicle or the environmental event. A transmitter is operatively coupled to the processor and configured to transmit one or both of an alert and a condition assessment report for the structure to a predetermined location in response to determining that the heavy load results from the superload vehicle or the environmental event.
