Abstract
Abstract A heating type hair waving appliance includes a bonnet in which the hairline area of the head of a patron is inserted and a plurality of infrared radiation lamps serving as a source of heat for heating the hairline area. A controller is implemented with a microcomputer semiconductor integrated circuit for receiving inputs applied via an input keyboard and placing the plurality of the infrared lamps into predetermined conditions. A solid state display provides a display of the operative state of the infrared lamps and an ultrasonic type atomizer is provided for generating moisture-laden mist which in turn is guided into the interior of the bonnet.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
59 words
A heating type hair waving appliance for use on a patron's hairline area comprising: a head supporting assembly; a plurality of heating means distributed throughout the interior of said head supporting assembly for heating different hairline regions of the patron's head; and microprocessor controller means for independently controlling the operation of each of said plurality of the heating means.
Claim 2
Dependent Claim
59 words
A heating type hair waving appliance for use on a patron's hairline area comprising: a head supporting assembly; a plurality of heating means distributed throughout the interior of said head supporting assembly for heating different hairline regions of the patron's head; and microprocessor controller means for independently controlling the operation of each of said plurality of the heating means.
Claim 3
Dependent Claim
84 words
A heating type hair waving appliance for use on a patron's hairline area comprising: a head supporting assembly; heating means provided within said head supporting assembly for heating the hairline area of the patron's head; temperature sensing means for monitoring the heating temperature of the hairline area being heated by said heating means; microprocessor controller means for controlling the operation of said heating means in response to the output of said temperature sensing means; and display means for displaying operation of said heating means.
Claim 4
Dependent Claim
84 words
A heating type hair waving appliance for use on a patron's hairline area comprising: a head supporting assembly; heating means provided within said head supporting assembly for heating the hairline area of the patron's head; temperature sensing means for monitoring the heating temperature of the hairline area being heated by said heating means; microprocessor controller means for controlling the operation of said heating means in response to the output of said temperature sensing means; and display means for displaying operation of said heating means.
Claim 5
Dependent Claim
91 words
A hair waving appliance for use on a patron's hairline area comprising: a support; a plurality of distributed heaters for independently heating different hairline regions of the patron's head; a plurality of temperature sensors each associated with one of said distributed heaters for independently sensing the temperature of each of said different hairline regions; microprocessor controlled means for controlling the operation of each of said heating means in response to the output of its associated temperature sensor, said microprocessor control allowing said different hairline regions to be regulated at different temperatures.
Claim 6
Dependent Claim
91 words
A hair waving appliance for use on a patron's hairline area comprising: a support; a plurality of distributed heaters for independently heating different hairline regions of the patron's head; a plurality of temperature sensors each associated with one of said distributed heaters for independently sensing the temperature of each of said different hairline regions; microprocessor controlled means for controlling the operation of each of said heating means in response to the output of its associated temperature sensor, said microprocessor control allowing said different hairline regions to be regulated at different temperatures.
