Embodiment Construction

[0028] according to figure 1 A first embodiment of the invention is shown, providing an oscillator 1 connected to an "antenna", ie a transmit detector 2, arranged to generate a frequency of approximately 5 MHz. A row of receiving detectors 3, 4, 5 receives the signal emitted from the transmitting detector 2, and each receiving detector 3, 4, 5 is connected to a respective rectifier 6, 7, 8 such as a diode bridge, from which The rectifier passes the signal to a multi-band analog-to-digital converter (ADC) input to the microprocessor 9 . Likewise, the signal taken directly from the oscillator is provided to the ADC so that the amplitude of the transmitted signal can be used to normalize the received signal.

[0029] A memory device 10 connected to the microprocessor contains reference data of conductance and capacitance for different skin types such as dry skin and oily skin. The memory device 10 also contains reference data for different skin types under different conditions,...

Abstract

The apparatus comprises a) a set of probes each having tips arranged to simultaneously touch the skinand define a predetermined pattern on the skin, at least one of the probes being arranged to transmit a pulsed electrical signal and at least one of the probes (which me be the same as or different to the transmitter probe) being arranged to receive the transmitted electrical signal; b) a signal detector for detecting the or each received electrical signal; c) means for comparing a numerical value obtained from at least one detected signal from the signal detector with at least one predetermined numerical value; and d) means for providing an output when said value obtained from the detected signal differs from the predetermined numerical value by more than a predetermined amount. The apparatus is used to control intense pulsed light devices used for local treatment ofvarious skin conditions and to influence non-desired hair growth.

Description

technical field [0001] The present invention relates to devices for detecting the presence of skin, and more particularly to use as a safety device for ensuring that a phototherapy device does not act on a target area where no skin is present. The invention also includes methods of detecting the presence of skin suitable for controlling the operation of such phototherapy devices for therapeutic and cosmetic purposes. Background technique [0002] As is well known, light therapy devices come in a wide variety. For example, intense pulsed light (IPL) is used in the topical treatment of various skin conditions and to affect undesired hair growth. [0003] It is important to ensure that the light is aimed at the area being treated, rather than a delicate body part such as the eye, and that the light is not used on undetected areas of the skin. [0004] US 2004 / 0167502A1 discloses an apparatus and method for detecting the presence of human skin by evaluating the spectrum of ele...
