摘要： A system for adjusting a bias voltage of a flame sensing system. The system may use pulse width modulation to adjust the bias voltage. The system may have a flame sensing rod that conveys an electrical equivalent circuit of a flame presence to a detector via low pass filter. An excitation voltage may be conveyed via a DC blocking mechanism to the sensing rod. A pulse width modulation signal may be conveyed via a bias resistor to a node of the low pass filter and the detector. The input of an A/D converter may be that of the detector for flame signals. Also, leakages between the node of the A/D converter connection and the voltage source and/or ground may be detected and compensated. Further, leakage of the DC blocking mechanism may be minimized.

摘要： An analog to digital converter used along with a variable resistive sensing means utilizes the capabilities of a microprocessor to charge and discharge a capacitor. The time required for this capacitor to discharge is dependent upon the value of the variable resistive sensing means. Circuitry is used to create a pulse whose pulse width is equal to the discharged time of a capacitor through the variable resistive sensing means.

摘要： A power supply usable with various size loads has an input circuit receiving pulses of voltage at 25 kilohertz. The pulses are modulated in width depending upon the input to a pulse-width modulation IC receiving inputs indicative of the output voltage and current delivered to the load. A backup current limiting circuit comprising a transistor which is biased by the voltage to the load, limits the signal to the pulse-width modulation IC to limit the width of the pulse to maintain the output current within limits.

摘要： A controller area network (CAN) has a plurality of nodes connected to transmit and receive data over a serial data line using an interface circuit to connect the node to the data line. Each interface circuit includes an isolation element, typically a diode, to connect the interface circuit to the data line. An indicator element in the interface circuit is powered when the node is transmitting. The isolation element in each node prevents other nodes while transmitting, from powering the indicator element in its node.

摘要： A flame rectification type flame sensor circuit and method in which a generator injects periodic pulses of alternating voltage into a flame region, the voltage across the flame region being processed by a filter/amplifier which, in proper operation, produces a non-zero output signal only during the time a flame is present and a pulse of alternating voltage is being supplied by the generator. Final indication of a flame is produced only if a non-zero output signal occurs during the time a pulse of alternating voltage is being supplied, and not during the time between successive pulses of alternating voltage. Failure of an electrical component in the filter/amplifier is indicated if a non-zero output signal occurs during the time between successive pulses of alternating voltage.

摘要： 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.

摘要： A recovery algorithm for a setback thermostat uses the intersection of the space temperature with a sloped recovery temperature line which approximates the change in temperature as a function of time during recovery of the temperature controlled space from a setback temperature, to determine the time at which recovery to the occupancy temperature should begin. The thermostat starts recovery when the current space temperature crosses the recovery temperature line. A useful feature of the apparatus and method which implement the invention, computes and constantly updates the slope of the recovery temperature line. The update of the recovery temperature line slope is based on miss time, i.e., the time between actually achieving the desired next set point temperature and the next set point time associated with the next set point temperature. If the heating or cooling load on the space changes, the recovery temperature will frequently cross the recovery temperature line at a different time, causing recovery to start at a time more compatible with the current heating or cooling load in order to complete recovery at or near the desired time.

摘要： A microprocessor-based power switching circuit responds to a common form of noise by disconnecting power from the controlled apparatus. The microprocessor provides an alternating voltage when power is to be provided, and the alternating voltage is converted by a detector circuit to a voltage close to ground which cuts off a transistor. When the transistor is cut off, an interface circuit places a thyristor which performs the actual power switching, into conduction. Noise on the base of the transistor can only drive it into conduction which then puts the thyristor into non-conduction.
