In a polishing process, the endpoint is declared after detecting that the friction between the polishing tool and the structure being polished is rising, then determining that the friction is falling, then waiting for a predetermined period of time. The fitted magnetic panel magnetically attaches to body surfaces and protects the surface from damage from the elements or from light to moderate collisions. , oral and personal care products, comprising a tetrabasic zinc-amino acid or trialkyl glycine-halide complex, and cysteine in free or in orally or cosmetically acceptable salt form, together with methods of making and using the same. The electrostatic field reducer and electrodes reduce the electrostatic field on the surface of the media and thereby reduce printing defects. The resilient spring member transmits the driven rotational movements of the alternator pulley by the serpentine belt to the hub structure such that the alternator shaft is rotated in the same direction as the alternator pulley while being capable of instantaneous relative resilient movements in opposite directions with respect to the alternator pulley during the driven rotational movement. The first buzzer operates for the duration of a first pre-set time period, and the floodlight, which is delayed from operating for the duration of a second pre-set time period, operates for the duration of a third pre-set time period which is extendible upon further activation of the activity sensor.
