Smart laser hair growth helmet

A low-level, laser-light, scalp-hair therapy device having on its interior a plurality of power-controlled laser diode arrays that generally direct a monochromatic and coherent therapeutic light at the scalp of a user wearing it, comprising:

• a plastic helmet fenestrated with cooling air vents that pass air heated during operation from inside to outside for cooling;
• a rechargeable battery and controller with an operational status display and that are mounted together with a master-switch, and which are all disposed within the plastic helmet;
• a controller connected to operate the plurality of power-controlled laser diode arrays according to predefined therapeutic profiles and sessions, and that maintains an operational status and log with a microcontroller;
• a proximity sensor connected as a user scalp presence detector, and connected to the controller to shut off battery power to the plurality of power-controlled laser diode arrays if the user scalp is not then detected as being proximate;
• at least one temperature sensor connected to the controller and connected to shut off battery power to the plurality of power-controlled laser diode arrays if a particular part or area of the device exceeds a predefined temperature;
• a speech synthesizer and a loudspeaker connected to the controller and that speak instructions and the operational status of the device to the user in a spoken language;
• a wireless transceiver capable of Internet communication with a centralized server, and connected to exchange status and operational data with the controller;
• a plurality of petal cutouts in the outside edges of the flexible printed circuit that are symmetrical along a central spine, and that then permit the flexible printed circuit to be cupped into and attached inside said concave bottom side of the plastic helmet;
• a color-variable and intensity-variable light mounted inside the master-switch and electrically connected to the controller and having digital logic that can communicates the operational status of the scalp-hair therapy device by modulated light made visible to a user;
• separate external panels that are attached from outside a domed outer shell of the plastic helmet, and that include studded bosses that pass through reliefs in the domed outer shell to provide the studded bosses to which the flexible printed circuit is attached;
• and
• wherein, the vents are such that temperature rises inside the helmet during operation are limited to two degrees Fahrenheit over ambient outside;
• and
• wherein, the laser arrays are assembled from a number of vertical cavity surface emitting laser (VCSEL) devices operating at a wavelength of about 678-nm and distributed over one side of a flexible printed circuit mounted by studded bosses inside the plastic helmet.
