1. A device for the treatment of tissue comprising:
- a light source assembly having a plurality of sections, each section having;
at least one light source disposed to irradiate said tissue; and
at least one tissue proximity sensor disposed to indicate when the section is in close proximity to said tissue; and
a controller coupled to said tissue proximity sensors and said light sources, wherein, for each section, said controller is configured to control the at least one light source in response to said at least one tissue proximity sensor.

Abstract
An apparatus is disclosed for use by a consumer in a non-medical setting that uses at least one low power optical radiation source in a suitable device that can be positioned over a treatment area for a substantial period of time or can be moved over the treatment area one or more times during each treatment. The apparatus can be moved over or applied to or near the consumer'"'"'s skin surface as light or other electromagnetic radiation is applied to the skin. The apparatus contains a control system that controls the radiation source, which may include various sections that are controlled independently.

14. A photocosmetic device for the treatment of tissue comprising:
-
an aperture having first and second areas;
a light source oriented to emit light through said first and second areas;
a controller electrically connected to said light source and configured to receive input signals and transmit output signals;
a first sensor electrically connected to said controller, said first sensor configured to provide a first sensor signal to said controller when said first area is in close proximity to said tissue;
a second sensor electrically connected to said controller, said second sensor configured to provide a second sensor signal to said controller when said second area is in close proximity to said tissue;
a power source electrically connected to said controller and electrically connected to said light source, said controller configured to alter the amount of power delivered to said light source in response to said first and second sensor signals. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method for the treatment of tissue with a photocosmetic device having an aperture:
-
receiving a first sensor signal corresponding to a first area of said aperture and indicating whether said first area is in close proximity to said tissue;
irradiating said tissue with light from said first area when said first area is in close proximity to said tissue;
receiving a second sensor signal corresponding to a second area of said aperture and indicating whether said second area is in close proximity to said tissue; and
irradiating said tissue with light from said second area when said second area is in close proximity to said tissue. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33)

34. A method for controlling a handheld device for treating tissue comprising the steps of:
-
determining whether a first portion of an aperture of the device is in close proximity to said tissue;
generating a first sensor signal indicating the proximity of the first portion of said aperture to said tissue;
determining whether a second portion of the aperture is in close proximity to the tissue;
generating a second sensor signal indicating the proximity of the second portion of the aperture to the tissue;
generating first and second control signals in response to said first and second sensor signals;
wherein said first control signal causes a first light source to emit light through said first portion when said first portion is in close proximity to said tissue and wherein said second control signal causes a second light source to emit light through said second portion when said second portion is in close proximity to said tissue.

35. A method for the treatment of tissue using a device having first and second apertures comprising:
-
receiving a first sensor signal corresponding to said first aperture and indicating whether said first aperture is in close proximity to said tissue;
irradiating said tissue with light from said first aperture when said first aperture is in close proximity to said tissue;
receiving a second sensor signal corresponding to said second aperture of and indicating whether said second aperture is in close proximity to said tissue; and
irradiating said tissue with light from said second aperture when said second aperture is in close proximity to said tissue.

36. A handheld photocosmetic device adapted for the treatment of tissue having varying contours comprising;
-
a housing having a head portion containing a plurality of apertures;
a light source assembly located substantially within said housing and oriented to emit light through said plurality of apertures; and
a controller for enabling the application of light through one or more of the plurality of apertures. - View Dependent Claims (37, 38, 39, 40, 41, 42)

43. A handheld photocosmetic device adapted for the treatment of tissue having varying contours comprising;
-
a housing having a head portion containing an aperture;
a light source located within said housing and oriented to emit light through said aperture;
a power supply electrically connected to said light source configured to provide electrical power to said light source;
wherein said aperture includes a broad portion having a first width configured to emit light to a relatively larger area of tissue and a narrow portion having a second, smaller width configured to emit light to a relatively smaller area of tissue. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51, 52, 53)
