Abstract
Abstract A temperature control apparatus for a heating or cooling apparatus with a temperature sensor, a computer producing a control signal in response to temperature during an operation period and thereafter entering a halt period, a transmitter for sending the control signal to the heating or cooling apparatus and a timer for controlling the computer. The timer is activated by commencement of the operation period to reactivate the computer after a predetermined time.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
261 words
A wireless type control apparatus for controlling a heating or cooling apparatus comprising: temperature sensing means for producing a signal indicating a temperature; computer means for receiving said temperature signal and for producing a control signal in response to said temperature signal during an operation period, and entering a halt period at times other than said operation period and for producing a command signal which is at a first level when the computer means is in said operation period and at a second level when in said halt period, said computer means entering said halt period upon receiving a halt signal at a halt signal input terminal thereof; transmitting means for transmitting said control signal to said heating or cooling apparatus; and an R-C timer, comprising a resistor and a capacitor, for controlling when said computer means is to be in one of said operation and halt periods, said R-C timer coupled to said computer means to receive said command signal, and to begin a charging sequence when said command signal is at said first level, said R-C timer having its output coupled to said halt signal input terminal of said computer means as said halt signal, said halt signal produced to halt said computer means after a voltage buildup on the capacitor C of said R-C timer reaches a predetermined level, said computer means then causing said command signal to be output at said second level which allows said R-C timer to discharge, so that said halt signal is removed from the halt signal input terminal after a predetermined time.
Claim 2
Dependent Claim
261 words
A wireless type control apparatus for controlling a heating or cooling apparatus comprising: temperature sensing means for producing a signal indicating a temperature; computer means for receiving said temperature signal and for producing a control signal in response to said temperature signal during an operation period, and entering a halt period at times other than said operation period and for producing a command signal which is at a first level when the computer means is in said operation period and at a second level when in said halt period, said computer means entering said halt period upon receiving a halt signal at a halt signal input terminal thereof; transmitting means for transmitting said control signal to said heating or cooling apparatus; and an R-C timer, comprising a resistor and a capacitor, for controlling when said computer means is to be in one of said operation and halt periods, said R-C timer coupled to said computer means to receive said command signal, and to begin a charging sequence when said command signal is at said first level, said R-C timer having its output coupled to said halt signal input terminal of said computer means as said halt signal, said halt signal produced to halt said computer means after a voltage buildup on the capacitor C of said R-C timer reaches a predetermined level, said computer means then causing said command signal to be output at said second level which allows said R-C timer to discharge, so that said halt signal is removed from the halt signal input terminal after a predetermined time.
Claim 3
Dependent Claim
53 words
A wireless type control apparatus according to claim 1, wherein said temperature sensing means includes comparison signal producing means for producing a comparison signal representative of a desired temperature in response to an output of said computer means, and means for comparing said comparison signal from said producing means with said temperature signal.
Claim 4
Dependent Claim
39 words
A wireless type control apparatus according to claim 2 in which said comparing means includes an A-D converter, said A-D converter receiving said comparison signal and said temperature signal and producing a digital output indicative of a comparison therebetween.
Claim 5
Independent Claim
174 words
A method of operation of a wireless type control apparatus including a temperature sensing means, a microcomputer having a CPU, a transmitting means, and a timer means having a C-R timer, comprising the steps of: sensing a temperature and producing a temperature signal corresponding to the sensed temperature; producing a control signal from the CPU in response to said temperature signal; transmitting the control signal from the transmitting means to an apparatus to be controlled in response to a transmit command from said CPU; producing a given signal from the CPU when one of said producing and transmitting cycles is completed; charging the C-R timer in response to the given signal; producing a signal from the CPU and causing the CPU to enter a halt state when a voltage of the C-R timer has reached a prescribed potential; allowing the voltage of the C-R timer to discharge; and shifting from the halt state of the CPU to an operation state when the discharged voltage of the C-R timer has fallen to a predetermined potential.
Claim 6
Independent Claim
174 words
A method of operation of a wireless type control apparatus including a temperature sensing means, a microcomputer having a CPU, a transmitting means, and a timer means having a C-R timer, comprising the steps of: sensing a temperature and producing a temperature signal corresponding to the sensed temperature; producing a control signal from the CPU in response to said temperature signal; transmitting the control signal from the transmitting means to an apparatus to be controlled in response to a transmit command from said CPU; producing a given signal from the CPU when one of said producing and transmitting cycles is completed; charging the C-R timer in response to the given signal; producing a signal from the CPU and causing the CPU to enter a halt state when a voltage of the C-R timer has reached a prescribed potential; allowing the voltage of the C-R timer to discharge; and shifting from the halt state of the CPU to an operation state when the discharged voltage of the C-R timer has fallen to a predetermined potential.
Claim 7
Dependent Claim
37 words
A method as in claim 4, further including the step of producing a comparison signal representative of a desired temperature based on an output from the CPU, and comparing the sensed temperature signal with the comparison signal.
