Abstract
Abstract A hair treatment system and appliance which are precisely and accurately controlled by a microprocessor in which data stored in memory is utilized to control different types of hair treatment programs for different types of hair. The system is utilized in association with a head bonnet adapted to be placed about the hair being treated and having a heater therein for heating the hair during the treatment program. A control panel allows a selection and entry to be made on the type and porosity of the hair to be treated, from eleven different possible combinations thereof indicated on the panel. A memory has stored therein a treatment time and temperature for each of the possible combinations, and a processing circuit is responsive to the particular entry to retrieve the proper treatment time and temperature from memory. A separate temperature sensor probe is utilized to detect the temperature produced by the heater at the hair during its treatment. The processing circuit monitors the temperature sensor, and is responsive to its output to control the heater, maintaining it substantially at the temperature retrieved from memory. The processing circuit further monitors the treatment time, and turns off power to the heater after the correct treatment time has elapsed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
222 words
Apparatus for treating hair in association with a head bonnet adapted to be placed about the hair being treated and having a heater for heating the hair during the treatment, comprising: a. a control panel having a plurality of selection switches, with each selection switch representing a different hair type for allowing the selection and entry of the type of hair to be treated from a plurality of possible hair types indicated thereon; b. a temperature sensor for detecting the temperature produced by the heater at the hair during the treatment thereof; c. a binary memory having stored therein as binary words a treatment time and temperature for each of the plurality of switches for the possible hair types indicated on the control panel; and d. a processing circuit means, comprising a microprocessor having said memory as a component thereof, responsive to the entry by actuation of a switch for the selected hair type, for retrieving from said memory the treatment time and temperature therefor, said processing circuit being responsive to said temperature sensor for controlling the heater of the head bonnet to maintain it substantially at the temperature retrieved from memory during the treatment, said processing circuit further including a timer for timing the treatment time retrieved from memory to turn off the head bonnet heater after the measured treatment time.
Claim 2
Dependent Claim
222 words
Apparatus for treating hair in association with a head bonnet adapted to be placed about the hair being treated and having a heater for heating the hair during the treatment, comprising: a. a control panel having a plurality of selection switches, with each selection switch representing a different hair type for allowing the selection and entry of the type of hair to be treated from a plurality of possible hair types indicated thereon; b. a temperature sensor for detecting the temperature produced by the heater at the hair during the treatment thereof; c. a binary memory having stored therein as binary words a treatment time and temperature for each of the plurality of switches for the possible hair types indicated on the control panel; and d. a processing circuit means, comprising a microprocessor having said memory as a component thereof, responsive to the entry by actuation of a switch for the selected hair type, for retrieving from said memory the treatment time and temperature therefor, said processing circuit being responsive to said temperature sensor for controlling the heater of the head bonnet to maintain it substantially at the temperature retrieved from memory during the treatment, said processing circuit further including a timer for timing the treatment time retrieved from memory to turn off the head bonnet heater after the measured treatment time.
Claim 3
Dependent Claim
58 words
Apparatus for treating hair as claimed in claim 1, including an AC power outlet plug for a separate head bonnet, said processing circuit means cycling AC power on and off to said AC power outlet plug to control the heater of the head bonnet to maintain it substantially at the temperature retrieved from memory during the hair treatment.
Claim 4
Dependent Claim
33 words
Apparatus for treating hair as claimed in claim 2, comprising a console mounted elevated above a base, said control panel being on said console and said AC power outlet being on said base.
Claim 5
Dependent Claim
44 words
Apparatus for treating hair as claimed in claim 3, said temperature sensor being mounted in a probe which is designed to be secured directly to the hair being treated, said probe being connected by an electrical connector to a plug connector on said console.
Claim 6
Dependent Claim
50 words
Apparatus for treating hair as claimed in claim 1, said control panel having an array of selector switches thereon, with one axis of the array indicating the classification of the hair to be treated, and a second axis of the array indicating the porosity of the hair to be treated.
Claim 7
Dependent Claim
82 words
Apparatus for treating hair as claimed in claim 5, for enabling two different types of treatment, either a conditioning program for the hair, or a permanent program therefor, said control panel including selector switches for allowing the selection and entry of either a conditioning program or a permanent program, and said memory having stored therein both a conditioning treatment time and temperature, and a permanent treatment time and temperature for each of the plurality of hair types indicated on the control panel.
Claim 8
Dependent Claim
52 words
Apparatus for treating hair as claimed in claim 6, said display panel having a plurality of LED selection indicators thereon, one LED for each type of hair in the array for indicating the selected hair type, and one LED for each of the conditioning and permanent programs for indicating the selected program.
Claim 9
Dependent Claim
28 words
Apparatus for treating hair as claimed in claim 1, said temperature sensor being mounted in a probe which is designed to be attached to the hair being treated.
Claim 10
Dependent Claim
15 words
Apparatus for treating hair as claimed in claim 1, said memory comprising a Read/Write memory.
