The control section of a control apparatus executes a first control for operating a voltage application section such as to cause a current to flow in a first direction through a gas sensor in a first period, and a second control for operating the voltage application section such as to cause a current to flow in a second direction, opposite to the first direction, through the gas sensor in a second period. The control apparatus changes the length of at least one of the first period and the second period based on a comparison between a first measurement value, which is the absolute value of a value measured by a sweep measurement section during execution of the first control, and a second measurement value, which is the absolute value of a value measured by the sweep measurement section during execution of the second control.

A system and method for sensor quality detection continuously monitors a context (vehicle state, proximal environmental factors, surrounding environmental conditions) surrounding a vehicle as well as actual sensor output. The system compares actual sensor output with expected sensor output to determine if the sensor has become degraded or if the degradation is due to the surrounding context. Once the system determines the context-based or actual degradation, it determines if the sensor is able to complete an assigned tasking with the degradation within the specific mission-based requirements of the sensor. Should the degraded sensor be unable to complete the task, the system transfers the tasking to a second vehicle equipped with an operational sensor.

Apparatus are configured to monitor lifespan of parts on a pressure regulator. These configurations may include sensors that generate signals in response to movement of parts on the pressure regulator. Processing circuitry can process the signals to identify data that corresponds to deflection of a spring inside of the pressure regulator. This data may correlate with duty cycle of a diaphragm. In one implementation, utilities can use the duty cycle to gauge useable lifespan of the diaphragm as well as other operating conditions that may prevail on the pressure regulator.

The method for monitoring the condition of the hydraulic system for predicting the risk of failure is designed for hydraulic systems, whose components include at least one pump (1) for transporting fluid through the distribution system of the hydraulic system. The hydraulic system simultaneously detects at least one current magnitude of pressure and the current value of speed of the pump (1), whereupon the current speed value is compared with the trend speed value obtained from the statistically processed archived data of speed from the previous operation of the pump (1) and/or with the reference speed value of the pump (1), whereupon the comparison result provides the condition and risk of failure of the hydraulic system.
