Abstract
Abstract A method for indicating the optimum time at which to turn meat over in a microwave oven. The method detects the point where the absolute humidity remains constant and no longer increases indicating that the temperature of the meat has reached an equilibrium point. At the temperature equilibrium point, the meat is ready to be turned over.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
151 words
A method for cooking a foodstuff of the type requiring turning during cooking in a microwave oven having a cooking cavity, a source of microwave energy, a controller including a programmable microprocessor, and means for sensing the time-dependent humidity in said cooking cavity, said method comprising the steps of: (a) placing said foodstuff on a first side thereof into said cooking cavity; (b) applying microwave energy from said source to said cooking cavity to heat said foodstuff; (c) sensing the time-dependent humidity of said cooking cavity with said sensing means while applying microwave energy to heat said foodstuff and providing said sensed humidity as an input to said programmable microprocessor; (d) determining in said microprocessor during the heating step when said time-dependent sensed humidity becomes substantially constant; and (e) providing an oven operator signal to turn said foodstuff to a second side thereof when said substantially constant humidity condition is reached.
Claim 2
Independent Claim
151 words
A method for cooking a foodstuff of the type requiring turning during cooking in a microwave oven having a cooking cavity, a source of microwave energy, a controller including a programmable microprocessor, and means for sensing the time-dependent humidity in said cooking cavity, said method comprising the steps of: (a) placing said foodstuff on a first side thereof into said cooking cavity; (b) applying microwave energy from said source to said cooking cavity to heat said foodstuff; (c) sensing the time-dependent humidity of said cooking cavity with said sensing means while applying microwave energy to heat said foodstuff and providing said sensed humidity as an input to said programmable microprocessor; (d) determining in said microprocessor during the heating step when said time-dependent sensed humidity becomes substantially constant; and (e) providing an oven operator signal to turn said foodstuff to a second side thereof when said substantially constant humidity condition is reached.
Claim 3
Dependent Claim
12 words
The method of claim 1 wherein said time-dependent humidity is absolute humidity.
Claim 4
Dependent Claim
56 words
The method of claim 1 further comprising the steps of: (a) measuring the time period during which the microwave oven door is open and said source of microwave energy is non-operative while said foodstuff is being turned to said second side; and (b) adjusting the food cooking time when said time period exceeds a predetermined time.
Claim 5
Dependent Claim
22 words
The method of claim 3 wherein said food cooking time adjusting step is carried out by a program stored in said microprocessor.
