The present invention relates to an information processing apparatus and method capable of avoiding communication interruptions during communication. A startup circuit is connected to the bias network, the startup circuit operable to assist the bias network in setting the amplifier bias current during a startup period. The resulting gloves have better barrier integrity. By decreasing the amount of light incident upon these intervening portions, the amount of noise in the detection signal can be decreased when using certain optical detection systems. The sliding focusing cell includes a rigid outer housing that is resistant to bending and a rear sliding lens cell that is biased in a rearward direction to be self-centering during recoil.
