摘要： A beverage dispensing system includes a beverage dispenser which forms and dispenses a beverage and a processor for monitoring the beverage dispenser. The beverage dispenser operates under various parameters including a first parameter that is indicative of the quality of the beverage to be dispensed and a second parameter that is indicative as to when routine maintenance is to be scheduled. The processor monitors the various parameters under which the beverage dispenser operates and determines whether the first parameter is outside of a predetermined range. If the first parameter is outside the predetermined range, the processor sends a signal regarding a request for immediate repair service. The second parameter is also monitored and the routine maintenance is scheduled based thereon.

摘要： A system for detecting and isolating faults in a two-wire communications loop which includes a number of node circuits dispersed along the loop. Each node circuit executes a fault detection algorithm and selectively switches its connections to adjacent node circuits to effectively isolate itself from the fault condition. When all node circuits have completed their respective fault detection algorithms the fault condition is disconnected from the two-wire communications loop.

摘要： A back-up uninterruptible power system has a power supply path from input terminals connected to AC power system lines to normally supply power to a load. Upon the occurrence of a line fault, a static switch in the power supply path interrupts the connection between the AC power lines and the load and an inverter is turned on to provide power derived from an auxiliary battery through a transformer to the power supply path to supply AC power to the load. By using the static switch, switching from line connection to backup power can be done quickly, within a half cycle, so that substantially no interruption of the output waveform is observed. The inverter can be operated to provide a commutation pulse to the SCRs in the static switch to commutate an SCR which might otherwise continue conducting after the triggering signals to the gates are cut off and before the inverter supplies the AC power to the load. A relay connected between the input terminals and the static switch is controlled to open relay contacts after the static switch has interrupted the current flow to the load, thereby providing positive electrical isolation of the AC power system from the uninterruptible power system while allowing the mechanical relay contacts to switch only during times of no current. Line fault detection is carried out by creating a digital waveform composed of an average of prior cycles of the AC input waveform, converting the stored waveform to an analog signal, and comparing it with the present input signal in phase lock therewith to detect deviation of the input signal from the reference waveform.

摘要： The run-time on battery power available from an uninterruptible power system is accurately determined both during supply of power from the battery through an inverter to the load and during the time where power is supplied directly from an AC power system to the load. During power outages where power is supplied from the battery through the inverter to the load, the output voltage of the battery is directly measured as is the output current supplied to the load. The remaining run-time is determined utilizing the measured battery voltage, the measured output current, and system specifications including the full charge open circuit voltage of the battery, the allowable lower limit of battery voltage, and constants which are characteristic of the uninterruptible power supply and the battery. When power is supplied from the AC power system to the load, the open circuit voltage of the battery is measured initially, and then during the time that the battery is being recharged the open circuit battery voltage is calculated based on the initial open circuit voltage adjusted by a factor porportional to the time that the battery has been charged. The calculated open circuit voltage is used to calculate a battery voltage under load conditions by subtracting a term proportional to output current. These estimates are then utilized to calculate run-time in a manner similar to that used to calculate run-time when the battery is loaded. Thus, the inverter need not be turned on to supply power to the load solely for the purpose of testing the battery.
