Patent number: 5272650Abstract: An apparatus and method for providing a microprocessor having an inaccurate oscillator with a desired time base. The cycles of the output signal of the oscillator are counted by a first counter until the counted number equals a predetermined correction count. The first counter then produces a timing signal. A second counter is set up to create an actual count indicative of the number of output signals occurring during a predetermined number of periods of an AC signal generator connected to the microprocessor. A predetermined desired count is then subtracted from the actual count to produce a difference count. The difference count is then added to the old correction count to create a new correction count. By iterating this process until the difference count is equal to zero, the timing signal is modified until it is equal to the desired time base.Type: GrantFiled: September 25, 1990Date of Patent: December 21, 1993Assignee: Honeywell Inc.Inventors: John T.

Patent number: 5034671Abstract: The position of the power output member of a motor actuator which is normally controlled by a microprocessor in response to system-supplied condition signals may be set manually by providing a manually controlled selector signal to the microprocessor allowing manually controlled adjustment signals rather than the normal condition signals to form the parameters from which is derived the motor control signal. In the preferred embodiment, a first switch generates the selector signal and a second switch generates the adjustment signal. Such apparatus allows a repairer or installer to adjust a mechanical positioning system driven by the motor actuator while the positioning system is in a variety of precisely selected positions. This control system contains a feature allowing one to change position of the motor actuator's power output member either continuously or incrementally by appropriately manipulating the switch which generates the adjustment signal.Type: GrantFiled: January 25, 1990Date of Patent: July 23, 1991Assignee: Honeywell Inc.Inventors: Paul B.

Patent number: 5023816Abstract: The present invention is a method and apparatus for conditioning an AC input signal to a control system having a plurality of AC input signals. An AC system signal is substantially phase-synchronous with the AC input signal. The AC input signal is sampled a plurality of times to determine whether it is present or absent during a periodic half cycle of the AC system signal. A result value is determined which represents a state of the AC input signal determined a majority of the times that it was sampled. It is then determined whether the state of the result value has changed.Type: GrantFiled: January 27, 1989Date of Patent: June 11, 1991Assignee: Honeywell Inc.Inventors: Paul B. Patton, Kenneth B.

Patent number: 4974179Abstract: The present invention is a method and apparatus for preventing a decision made by a controller from being made based on incomplete information where the controller periodically runs a decision making routine. The controller makes decisions based on a plurality of AC input signals being present or absent. The presence or absence of the AC input signals is read by the controller during a read cycle performed during periodic half cycles of the AC system signal. The AC system signal and the AC input signals are substantially phase-synchronizes. Before the controller runs the decision making routine, the controller determines whether the presence or absence of the AC input signals has changed since the previous decision making routine. Where the presence or absence of the AC input signals has changed since the previous decision making routine, the decision making routine is delayed for a predetermined number of half cycles of the AC system signal.Type: GrantFiled: January 27, 1989Date of Patent: November 27, 1990Assignee: Honeywell Inc.Inventors: Paul B. Patton, Kenneth B. Kidder

Patent number: 4974180Abstract: A method and apparatus determine signal quality of AC input signals to a control system where the AC input signals and an AC system signal are phase-synchronous. A read cycle, for reading the AC input signals, is scheduled to be performed during periodic cycles of the AC system signal. The presence or absence of the AC system signal is determined. A number of good read cycles are counted where the good read cycles represent the read cycles performed when the AC system signal is present. A ratio is determined between the number of good read cycles counted during a predetermined time and a total number of read cycles scheduled to be performed during the predetermined time.Type: GrantFiled: January 27, 1989Date of Patent: November 27, 1990Assignee: Honeywell Inc.Inventors: Paul B. Patton, Kenneth B. Kidder

Patent number: 4965755Abstract: The present invention is a method and apparatus for monitoring a plurality of AC input signals to a control system. An AC interrupt signal is generated, based on an AC system signal which is substantially phase-synchronous with the AC input signals, for an interrupt time period corresponding to a time period when the AC system signal exceeds a predetermined threshold voltage. The AC interrupt signal is verified and a timer is set for a pseudo-random time value. The AC input signals are sampled when the timer has reached the pseudo-random time value to determine the presence or absence of valid AC input signals.Type: GrantFiled: January 27, 1989Date of Patent: October 23, 1990Assignee: Honeywell Inc.Inventors: Paul B.

Patent number: 4923117Abstract: A burner control system has a microprocessor for testing parameters of operation and for indicating deviations from a preset range for each. The sensors monitoring the parameters provide their outputs as analog voltages to analog to digital (A/D) converters which provide the parameters in digital form. Tests using preset voltage standards increase the likelihood of A/D converter accuracy. In addition, as operating conditions for the burner change, different preset ranges are used for each sensor output when testing them so as to provide maximum confidence of proper burner operation.Type: GrantFiled: March 13, 1989Date of Patent: May 8, 1990Assignee: Honeywell Inc.Inventors: Wilmer L.

Patent number: 4880376Abstract: Damper position of a damper in a heating system is monitored. The damper is movable between end positions in response to movement of a motor shaft. The motor shaft moves in response to a movement request signal. A shaft position signal is received by a position detector and has a value representative of position of the motor shaft. When the damper reaches an end position, it is determined whether the value of the shaft position signal is within a predetermined tolerance. If it is outside of the tolerance, then the system is shut down as unreliable; otherwise, the shaft position signal is recalibrated to maintain accuracy.Type: GrantFiled: January 27, 1989Date of Patent: November 14, 1989Assignee: Honeywell Inc.Inventors: James I.

Patent number: 4858885Abstract: An anti-bounce system for control of critical loads is provided. A control system contains two subsystems. The first subsystem functions for normal control of the critical loads, but has a relatively long information processing time. This long time might prevent the system from controlling the loads in a safe manner. The system has a second subsystem that has a very rapid processing time. Both of the subsystems are connected to the load by coupling means to monitor as a feedback signal the exact state of the loads. The second subsystem overrides the first, and disconnects power whenever there has been an interruption of power for a short period of time.Type: GrantFiled: June 15, 1988Date of Patent: August 22, 1989Assignee: Honeywell Inc.Inventors: Kenneth B.

Patent number: 4835670Abstract: A microcomputer control utilizes a nonvolatile memory with an interlock. The interlock functions upon the removal of the microcomputer control from a base or from a mounting surface, and its reinstallation. The removal and reinstallation deletes memory and requires reprogramming. This prevents the removal of a microcomputer control that is protected by battery backup without reprogramming the memory. This safety function is particularly useful in flame safeguard or burner control equipment where the interchange of microcomputer fuel burner controls without reprogramming for the particular burner could create a hazard.Type: GrantFiled: January 21, 1988Date of Patent: May 30, 1989Assignee: Honeywell Inc.Inventors: Wilmer L.
