An image displaying apparatus includes an image display that displays an image, and a controller that determines an image and controls the image display to display the determined image. The electronic circuit is comprised of two functional blocks, in which the variable transducer capacitance is first transformed and represented by a frequency modulated signal by a variable frequency oscillator, and subsequently converted to a digital delta-sigma representation using a frequency delta-sigma modulator. A modeling client can host modeling logic and an application programming interface to create, access, manipulate, and importexport modeling objects used in modeling applications, such as engineering, medical, financial, and other modeling platforms. Thus when one of the first backboards is moved to an open position, access is provided to the pair of battery backup units mounted on the first backboard so moved and to the pair of battery backup units mounted on the opposing second backboard. The cover may be bondingly connected to or crimped about the pot.
