An active power-on reset current comparator circuit creates a POR signal for resetting logic devices and masking reference startup signals during the initial power supply ramp of an integrated circuit. A pair of retaining bands connect the opposite temples of each of the eyeglasses, so that when a user dons one of the pairs of eyeglasses, the other hangs against their person, thereby being protected, secured and readily available. A bracket is mounted to the fore end of the stock to allow the legs of the bipod to be pulled clear of the channels and then rotated down. For each set of contemporaneous frames in time sequence order, the main layer of each keyframe is compressed using an inter-frame compression technique. In one embodiment accumulating points includes accumulating awards.
