Abstract: An apparatus for aesthetic manipulation of the skin having a large pulsator with plurality of light emitting diodes of at least two different wavelengths and a small pulsator with one light emitting diode. A frequency modulating means automatically modulates the emitting frequency of the light emitting diodes to a plurality of different frequencies. A power output modulating means modulates the power output of the light emitting diodes. A phase switching means allows selection between a plurality of operating phases, each operating phase operating the frequency modulating means and power output modulating means in a different predetermined manner. Calibration means connected in circuit with the light emitting diodes calibrates the power output of the light emitting diodes. A vibration means vibrates the large pulsator. A vibration switching means selectively activates the vibration means.

Abstract: Methods and apparatus for providing a device, such as a treatment device, on a pay-per-use basis are disclosed. Generally, a wholesaler supplies a treatment device to a retailer. The retailer pays the wholesaler on a per use basis, which is regulated by a digital key, such as a smart card attached to the treatment device via a smart card reader. When the value of the digital key drops below a threshold (e.g., only ten treatment sessions remaining), an alert is generated by the treatment device. When the value of the digital key is reduced to zero, the treatment device does not operate until the digital key is replenished or replaced.

Abstract: An apparatus for aesthetic manipulation of the skin having a large pulsator with plurality of light emitting diodes of at least two different wavelengths and a small pulsator with one light emitting diode is disclosed. A frequency modulator automatically modulates the emitting frequency of the tight emitting diodes to a plurality of different frequencies. A power output modulator is provided to modulate the power output of the light emitting diodes. A phase switching subsystem allows selection between a plurality of operating phases, each operating phase operating the frequency modulator and power output modulator in a different predetermined manner. Calibration subsystem connected in circuit with the light emitting diodes calibrates the power output of the light emitting diodes. A vibrator is provided to vibrate the large pulsator. A vibration switching subsystem selectively activates the vibrator.

Abstract: An interface unit for coupling an international-type pay-telephone to a land-based or cellular telephone system. The interfacing unit of the invention has a microcomputer, and an associated EPROM in which is stored the exchanges of the telephone numbers that are accessible by that local payphone-terminal, which EPROM also stores a table indicative of the tariffing rates associated with the respective exchanges called. The invention also includes the tone-detectors for detecting the dialed DTMF digits of the pay-telephone, for the conversion thereof for storage in the microcomputer for the determination of a valid telephone number dialed in order to determine the associated tariffing rates. The tone detectors also detect the tone-signals received from the telephone system. The invention also includes "isolating" switching circuitry for isolating the coin-operated pay terminal from its couplement to the telephone system until the telephone call has been connected.
