What are the Types of Mechanical Splices for Rebars?

Compression Only Mechanical Splices or End Bearing Splices. As it may be noticed from its name, this type of splice can resist compression stress merely. The compressive stress is transferred by vertical bearing from one bar to another one. Compression only mechanical splices can be used when tension stress is not occurred.

Mechanical Sensor - an overview | ScienceDirect Topics

Mechanical sensors are one of the most commonly used classes of sensors for biomechatronic applications. Force sensors can be used to detect tensile, compressive, shear, torsional, bending, or frictional forces. Touch sensors are devices which measure the parameters of contact between the sensor and an object. Touch sensors measure a contact ...

DVT Prevention: Intermittent Pneumatic Compression Devices

The devices use cuffs around the legs that fill with air and squeeze your legs. This increases blood flow through the veins of your legs and helps prevent blood clots. Intermittent pneumatic compression (IPC) devices are used to help prevent blood clots in the deep veins of the legs.
