A vibration-sensing field unit includes a base with at least one accelerometer, and a body mounted to the base. The base is composed essentially of a first material, while the body is composed essentially of a second material that is more flexible than the first material to reduce a vibration at the accelerometer caused by a mass supported by the body. In another embodiment, a vibration-sensing field unit includes at least one accelerometer and at least one ultrasonic transducer.

Relative displacements related to a structure are measured for use of a feedback signal in real time for the structural monitor of active and semi-active vibration. The monitors reduce structural movement caused by any source of natural or artificial vibration. A pre-stressed axial element is installed between two different points of the structure using a fixed connector and a flexible one. As the structure vibrates in response to an external “source”, a relative displacement is caused between two connecting points of the axial element, which can be measured based on the rotation φ of the flexible connector of the axial element. Discrete displacement can be obtained in real time of the whole structure where the axial element is installed. A modal monitor through active or semi-active devices can improve the structural behavior in some cases.

An analysis support apparatus includes: a feature interpreting section extracting a feature from a target analysis model generated from vibration data and classifying the feature into an abnormality determination feature, or a feature representing a vibration and enabling determining whether abnormality occurs; an abnormality determination range creating section identifying a range being determined to be abnormal of the abnormality determination feature of the target analysis model as an abnormality determination range; a similar model selecting section calculating an overlapping degree indicating how much the abnormality determination ranges of the target analysis model and one or more predetermined reference analysis models overlap and selecting, based on the overlapping degree, a similar analysis model similar to the target analysis model from the reference analysis models; and an abnormality range difference calculating section extracting a difference between the abnormality determination ranges of the target analysis model and the similar analysis model.

An example apparatus, such as a vibration testing tool, includes: a housing configured to fit into, and to connect to, a test slot configured to house a device for testing, with the test slot being part of a device test system; accelerometers connected to the housing and configured to output signals representing movement of the apparatus; and circuitry connected to the housing to generate data based on the signals, with the data being usable to determine multiple independent accelerations of the apparatus.

A system and method for opportunity-based hygiene monitoring and/or reminding is disclosed. Healthcare providers may have various opportunities to interact with a patient. As such, an opportunity-based focus in managing a healthcare environment may assist in assessing the various opportunities when interacting with the patient. For example, an opportunity-based analysis may be used for protocol compliance, such as compliance with hand hygiene protocols and/or PPE protocols. Further, infection analysis, patient care billing, staff locating, or workload analysis may be opportunity based in order to more efficiently manage the healthcare environment.
