Abstract: This invention proposed a temperature and optical frequency sensor using two different optical resonators. The fiber with different thermal expansion factor and refractive index can be used to sense the temperature variation. The optical resonators with different cavity lengths can be used to detect the frequency deviation. Applying a laser, a microprocessor and two optical resonators with different thermal expansion factors and resonate lengths, we invent the device which can detect the temperature and frequency simultaneously. Furthermore, the device can provide tunable and highly stabilized light source for optical system application.

Abstract: A quick connector including a pipe connector at one end and a connecting tube at an opposite end, a slide valve received inside the connecting tube and supported on a conical spring to block up the air passage way through the connecting tube, wherein when a matching male connector is inserted into the connecting tube, the slide valve is moved backwards to open the air passage way permitting a gas to pass from the pipe connector out of the connecting tube through the slide valve.
