An electrical connector includes a terminal assembly, a housing body, a first rib member and a second rib member. Access transistors are not necessary to perform read and write operations on the memory cell. The ferromagnetic thin film magnetoresistance elements have respective linear segments extending substantially along the Y-axis direction on a plane of a substrate disposed in a path of lines of magnetic force between the magnets and change their resistances in response to a change in a magnetic field directed in a direction orthogonal to the Y-axis direction in the plane of the substrate. In various embodiments, the strain gage system may comprise one or more transverse strain gages. In some embodiments, demographics information is also collected and used as a criterion for rendering the mental states of the viewers in a graphical format.
