A connector connected with a circuit board includes a housing and a main body. The dimensionally stable mounting module can include a front docking unit with front alignment elements for connecting the mounting module to a loadunload module, and a rear docking unit with rear alignment elements for connecting the mounting module to a main processing unit. As a result, the compression efficiency of a video compression apparatus or the picture quality of a reconstructed image can be greatly improved. The first end of the spring is hooked to the lever to bias a force to the lever in the direction opposite to the force from the sensor. The coagulant may be used in the molding process to releasably bond the substrate material to the mold and to bond to the antimicrobial to the substrate material. An annular groove extending between the conical faces has an end facing away from the combustion chamber which acts as a sealing edge upon contact of the valve sealing face with the valve seat.
