Abstract: The driver of a speaker for an automotive audio system includes a plurality of magnetic coils wound around a common bobbin. Each of the magnetic coils is connected to one of a plurality of amplifiers each of which output an identical drive signal. By applying the common drive signal to each magnetic coil, the electromagnetic field created around the magnetic coil is enhanced approximately in proportion to the number of magnetic coils. Due to this increased electromagnetic force, a vehicle panel serving as a sound-amplifying medium can be satisfactorily and successfully driven so as to produce high-quality sound. The amplifiers are adapted to amplify the low-frequency components of the audio signal from a main amplifier.

In a third embodiment, light beam transmitters are moved with the lower jaw relative to gratings so as to generate light pulses corresponding to movement of the lower jaw.

Abstract: A tiltable steering arrangement is arranged with the axis of rotation thereof relatively close to the steering wheel and in the near vicinity of a relatively heavy valve arrangement associated therewith.

Abstract: An apparatus for interfacing a speaker phone with a telephone network includes switch means for selectively connecting said interfacing apparatus with a telephone network to permit either conventional or automatic answering. A coupler, responsive to ringing signals on the telephone lines discharges a charging capacitor to a level sufficient to cause the automatic, hands-free interconnection of the speaker phone with the telephone line. In one embodiment, a timer is provided for limiting the length of time during which the speaker phone is coupled to the telephone line. A reset switch is provided in cooperation with the timer to permit the timing cycle to be reset upon command, thereby to shorten the time of connection if desired. The system operates in either a timed or extended mode. To bypass the timer and indefinitely extend the time during which the answered call is coupled between the telephone lines and the speaker phone, an extend switch is also provided to override the timer.

Abstract: The condition of a surface is sensed by cyclically moving two members having engaged surfaces relative to each other, driving the surfaces for only a portion of each cycle to set up a threshold kinetic energy level in accordance with the friction between the engaged surfaces, sensing the kinetic energy developed in one of the members due to moving the members relative to each other, comparing the developed kinetic energy with the threshold kinetic energy and controlling the cyclic movement of the members in accordance with the relationship between the kinetic energy threshold and the developed kinetic energy. The cyclic movement of the members is then used to provide a visual indication of the condition of one of the surfaces.
