| An electronic control system dynamically varies the output capacity of a compressor by controlling plural valves associated with the compressor to provide pressurized air to a distribution system at an appropriate rate. The control system operates in any of three modes for standalone operation, including continuous run, auto/dual pressure band, and target pressure modes. In the first two modes, pressure bands are dynamically calculated based on load and unload values entered by an operator. These electronic control systems can also be connected in a peer-to-peer network to coordinate control of up to 16 compressors feeding the same distribution system, so as to maintain a desired target pressure in the system. A modem connected to the system supports remote diagnostics, monitoring, and control. Specialized startup, operating, and shutdown diagnostic algorithms prevent damage to the compressor and avert unsafe operating conditions. | ||||||

| 7 | Method and sensor for the detection of cavitations and an apparatus containing a sensor of this kind | US09270958 | 1999-03-17 | US06206646B1 | 2001-03-27 | Peter Bucher |
| In a method for the detection of cavitations in a space to be monitored, the space to be monitored is monitored by means of a sensor (2) which is capable of learning. In this, a state in which cavitations arise in any case in the space to be monitored is first produced during a learning process for the duration of a first time interval (t1). After the completion of the first time interval (t1) a state in which cavitations do not arise in any case in the space to be monitored is produced for the duration of a second time interval (t2). In each of the two time intervals the sensor (2) learns which signals correspond to cavitations and which signals correspond to non-cavitations respectively in the space to be monitored. After the completion of this learning process the sensor compares the signals which arise during operation in the space to be monitored with the learned signals for cavitation and non-cavitation respectively and decides on this basis whether a cavitation has arisen in the space to be monitored or not and produces a corresponding output signal. | ||||||

| This electric compressor includes a compressor which rotates around an axis to compress a fluid, a motor which rotatably drives the compressor around the axis, and a control unit having a first component and a second component and controlling current supply to the motor during driving using the first component and the second component. An allowable current when the first component and the second component are exposed to the same temperature is set to be smaller in the second component than in the first component. The second component is disposed at a place in which cooling capability is greater than that of the first component so that allowable power of the second component at rated use is set to be greater than an allowable power of the first component. This electric compressor includes a temperature sensor which detects the temperature of the first component and a calculation unit which outputs an alarm signal when the temperature detected by the temperature sensor and a current flowing in the first component satisfy a predetermined condition. | ||||||
