    Abstract: Control circuitry for controlling a spa water heater, wherein a microcontroller is configured to detect zero crossings of an A.C. line voltage from a voltage sense signal, to cause closing of a first heater relay and a second heater relay, to detect the time at which heater current is initially sensed by a current sensor after the initial closing of the second heater relay, to measure a time delay between the time that the second heater relay is closed and the time at which heater current is initially sensed, and to adjust the time at which a second closing of the second heater relay occurs such that zero crossings of the heater current occur at the same time as zero crossings of the voltage waveform. The control circuitry further includes a voltage sense circuit comprising a first diode connected in series with a current limiting resistance connected in series with a Zener diode, which is in turn connected in series with an optical coupler LED.

    CPC classification number: G01K1/024

    Abstract: The present temperature monitor is comprised of a thermistor and a reference resistor connected to a capacitor in parallel. The capacitor is charged through the thermistor by a microcontroller to determine the thermistor charging time, discharged, and then charged through the reference resistor to determine a reference charging time. The thermistor charging time is divided by the reference charging time to determine the thermistor value, which is converted into an actual temperature by using a conventional algorithm. The microcontroller is programmed to activate various indicators to show the ambient temperature relative to one or more acceptable ranges, whether the temperature has reached the acceptable ranges within an acceptable time period, and whether the temperature has had an upward trend prior to reaching the acceptable ranges.

    Abstract: A flow control method and system including an algorithm for deciding to transmit an arriving packet into a processing queue or to discard it, or, in the case of instructions or packets that must not be discarded, a similar method and system for deciding at a service event to transmit an instruction or packet into a processing queue or to skip the service event. The transmit probability is increased or decreased in consideration of minimum and maximum limits for each flow, aggregate limits for sets of flows, relative priority among flows, queue occupancy, and rate of change of queue occupancy. The effects include protection of flows below their minimum rates, correction of flows above their maximum rates, and, for flows between minimum and maximum rates, reduction of constituent flows of an aggregate that is above its aggregate maximum. Practice of the invention results in low queue occupancy during steady congestion.
