The invention relates to a fiber reinforced rubber, for which the strength can be remarkably improved, the permanent compression set can be reduced and the anti-tear performance of rubber sheet can be enhanced. A method for preparing the fiber reinforced rubber comprises the following steps: a. mastication of rubber; b. reinforcing filler, fiber and accessory ingredient are added into the rubber for mixing; wherein, the fiber and the reinforcing filler is evenly mixed to prepare pre-dispersoid, and the pre-dispersoid is added into the rubber. As a preferred proposal, the method adopts styrene-butadiene rubber, nitrile rubber and neoprene which have the good properties of wearing resistance, pressure resistance, oil and water resistance and air tightness resistance as the rubber. The rubber sheet produced by the method can work under ultra-high temperature and pressure in various media for a long time with the maximum working temperature being 300 DEG C, and maintains good elasticity, less compressive deformation and excellent physical and mechanical properties which are reduced by not more than 20% compared with those at the normal temperature.

A mastication monitoring device 1 is provided with a probe 2 which is attached to a cheek in order to detect the concentration of reduced hemoglobin in the masticatory muscles. A photodetector 22 of the probe 2 detects light scattered in the masticatory muscles and delivers a signal of the amount of light received to a signal processing unit 3. The signal processing unit 3 computes the reduced hemoglobin concentrations (time-series changes) from the signals of the amount of light received, and further computes outputs S (time-series changes) corresponding to the time-series changes in the reduced hemoglobin concentrations. A mastication iteration counting unit 41 detects peaks in periodical changes of Sd which is the difference between the output S and the moving average value Sma of the output S and counts the peaks in periodical changes of Sd as the mastication iterations.

Provided are orthodontic corrector devices, related assemblies and methods which direct forces within the oral cavity. These corrector devices and assemblies include a flexible cantilever which is coupled to both a connector component and a force module. The cantilever acts to isolate adjacent components from mastication forces encountered during treatment. By resiliently deflecting in response to these inadvertent forces, the cantilever reduces the likelihood of device breakage and bond failure. Upon removal of these forces, the cantilever returns to its original orientation thereby maintaining the proper alignment of the corrector. Advantageously, the cantilever also allows the force module to be positioned further in the distal direction thereby enabling a greater range of connection options.
