Abstract: A measurement apparatus comprises a probe system (100) operably coupled, when in use, to a processing resource (134). The probe system (100) and the processing resource (134) are arranged, when in use, to measure an apparent thickness change of a volume of the medium (108) to be measured and to determine a physiological parameter using the measurement of the apparent thickness change.

Abstract: A connection structure for a camera module with an auto-focus feature and a module connector that eliminates the need for wires and FPCs for connection between motor signal terminals and a printed circuit substrate, as will as the need for solder connection operations is also eliminated. A cameras module with an auto-focus feature is equipped with a module base on which is disposed a camera signal contact terminal, and a main module unit on which is disposed a motor signal terminal extending from a side surface. A module connector includes an installation cavity for installing the camera module. A motor signal contact is disposed on the module connector, and the motor signal terminals are formed with a contact, which comes into contact with contacts of the motor signal contact when the camera module is installed in the installation cavity.
