A photosensitive device with a microlens array may be packaged for surface mount packaging and subsequent mass reflow processing without significantly degrading the optical performance of the microlens. The armrest includes a push button and a cable has a first end operably connected to the push button and a second end operably connected to the support rod, whereby the support rod is actuated when the push button is pushed. If the condition is satisfied, the pair is encoded as a corresponding extended ASCII code.
