A visual detection arrangement is provided in a milking system (3) comprising a robot arm (15) for attaching a teat cup (11) to a teat of a milking animal (8), and a control device (19) for controlling the movement of the robot arm. The detection arrangement comprises first visual detection means (17) provided on the robot arm for repeatedly determining the teat position relative the robot arm and second visual detection means (21) directed towards the milking animal. The second visual detection means (21) is provided for detecting a position of the animal in a longitudinal direction (x), and the control device (19) is initially provided for controlling the movement of the robot arm based on information of the position of the teat of the animal relative the animal itself, and on the detected longitudinal position of the animal.

A position indicator includes a time-constant circuit having an element whose characteristic continuously varies in response to operation represented as a continuous quantity such as writing force, and capable of switching the variation range of time constant in response to the variation in characteristic of the element in at least two ways; and a discharging / charging device capable of discharging the time-constant circuit from a predetermined voltage to a voltage below a specified voltage, or charging the time-constant circuit from the predetermined voltage to a voltage exceeding the specified voltage. Using the time-constant circuit and discharging / charging device, the number of waves of AC signals at a specified frequency is counted from the discharge start time to the time when the voltage falls below the specified voltage, or from the charge start time to the time when the voltage exceeds the specified voltage, by switching the variation range of time constant.

A method of adjusting a sensitivity parameter value for substrate defect inspection used in a substrate defect inspection apparatus compares, for each pixel value of a selected virtual inspection substrate, using reference pixel data to be used after adjustment, the deviation amount from an allowable range corresponding to the position thereof and the sensitivity parameter value before the adjustment when each pixel value is deviated from the allowable range, and updates the deviation amount as a new sensitivity parameter value when the deviation amount exceeds the sensitivity parameter value and a difference between the deviation amount and the sensitivity parameter value is equal to or less than a threshold value.

A hidden sensing device and its urinal are disclosed. The hidden sensing device, which is attached on some sanitary installations, comprises a conductivity sensor for detecting urine and a Micro-programmed Control Unit (MCU) for processing signals, wherein said conductivity sensor has electrodes extending into urine. The device further includes a microwave sensor controlled by the MCU to detect human's movements. When the conductivity sensor has detected urine, the MCU will turn on the microwave sensor to detect the human's presence or departure.

The engine misfire detection process according to one aspect of the invention first makes tentative detection on the occurrence or the non-occurrence of an engine misfire in execution of both vibration control and rotation speed control. In response to the tentative detection of an engine misfire, the engine misfire detection process subsequently makes final detection on the occurrence or the non-occurrence of an engine misfire. In the event of no final detection of an engine misfire, the engine misfire detection process makes tentative detection and final detection on the occurrence or the non-occurrence of an engine misfire in prohibition of the vibration control. In the event of still no final detection of an engine misfire, the engine misfire detection process makes tentative detection and final detection on the occurrence or the non-occurrence of an engine misfire in further prohibition of the rotation speed control. Even in the event of no final detection of an engine misfire in execution of both the vibration control and the rotation speed control, the procedure of the invention makes final detection on the occurrence or the non-occurrence of an engine misfire in prohibition of execution of the vibration control and further the rotation speed control. This arrangement desirably increases the detection frequency of engine misfires.

A printing apparatus capable of reducing the frequency of detection of a recording agent remaining amount and obtaining accurate information of the recording agent remaining amount. When a printed sheet is discharged, a CPU of a printer updates information representing the number of discharged sheets and stores the information into a memory of a print engine. The CPU refers to toner remaining amount information stored in a memory of a cartridge and determines whether there is a sufficient toner remaining amount in the cartridge. If there is no sufficient toner remaining amount, toner remaining amount detection is executed each time printing of one page has been performed. If there is a sufficient toner remaining amount, the toner remaining amount detection is executed when the number of discharged sheets coincides with a predetermined value.
