A vehicle is provided. The vehicle includes an electronic control unit and a pedal assembly. The electronic control unit selectively switches between a powered off state and a powered on state. The pedal assembly includes pedal arm, a target, and a switch. The pedal arm moves between a plurality of positions. The target moves with the movement of the pedal arm. The target generates a magnetic field strength. The switch activates when the magnetic field strength of the target exceeds a predetermined threshold. When the switch activates, a signal is sent to the electronic control unit to activate the electronic control unit from the powered off state to the powered on state.

This invention relates to a precision agriculture produce harvesting system and produce harvesting apparatus configured for integration with the system, an essential feature of which is a harvesting device subsystem (100) that includes a harvesting device, for instance pruning shears (102) and a harvesting separation stroke detector (108) housed within a control module housing (110) mounted to the shears (102). A person operating the pruning shears (102) produces discernible separation strokes when the handles (104) of the shears (102) are squeezed together to produce a shearing action. The stroke detector (108) detects the separation strokes of the shears (102). By the addition of the control module (108) to the pruning shears (102), the shears are essentially converted into a data logging device by means of which important aspects of a produce harvesting process can be digitised and supplied to a harvest data digital data processing system.

A display device includes multiple gate lines, multiple source lines, multiple pixel electrodes provided respectively in regions defined by the multiple gate lines and the multiple source lines, and multiple common electrodes provided to face the multiple pixel electrodes and used for both image display and touch detection. A second drive circuit supplies a touch drive signal to each of the multiple common electrodes. A touch detection circuit performs detection of a touch by an object on the display device, based on a touch detection signal received from each of the multiple common electrodes. The display device includes multiple touch detection regions. Among the multiple common electrodes, multiple common electrodes are arranged in each of the touch detection regions. In the display system, touch detection is performed in part of the multiple touch detection regions, and touch detection is not performed in rest of the multiple touch detection regions.

A system and a method for fault detection for a liquid level sensing device are provided. The liquid level sensing device comprising a plurality of switches arranged to measure variance in a liquid level. A sensing signal comprising a plurality of measurements indicative of the liquid level is received from the liquid level sensing device. Each measurement is obtained in response to one or more of the plurality of switches being in a given position at a given liquid level. It is determined, based on the sensing signal, whether the liquid level changed according to one or more expected change patterns. A fault signal is output in response to determining that the liquid level changed according to an abnormal change pattern.
