4 results about "Manual override" patented technology

The application provides a kind of override architecture of cut-off valve and its installation method and operation method, even if the control solenoid fails and is invalid, it can make the gas path normally on-off, the fuel path normally on-off, so as to normally supply oil to fuel tank or stop. The override architecture of cut-off valve comprises: a manual override device, which is arranged away from the control solenoid and the cut-off valve in the original machine pressure pipeline; a transmission assembly, the input end of which is connected to the manual override device, and the output end of which is connected to the original machine pressure pipeline, which can transmit the movement of the manual override device to the original machine pressure pipeline; an elastic sealing assembly in the pipe, which is connected to the output end of the transmission assembly, and blocks the gas inlet of the original machine pressure pipeline to form a normally closed sealing structure, when the manual override device works, the gas path is conducted, and the fuel path is conducted, when the manual override device stops working, the gas path is disconnected, and the fuel path is disconnected.

An automatic leveling and predictive balancing system for a tractor includes a laterally translatable counterweight assembly mounted to a standard hitch. The system dynamically repositions the counterweight in response to tilt sensor data or, in advanced embodiments, in anticipation of unlevel terrain based on speed, heading, and stored terrain data. The system comprises a weight compartment, a drive mechanism, and a controller operably coupled to a sensor array. The controller actuates the counterweight automatically to improve stability and traction. A predictive mode evaluates operational parameters to initiate weight shifting prior to encountering terrain changes. Manual override controls May also be included.

An electronic shower valve including a coaxially aligned motor and gear assembly received within a valve body and configured to move a flow control element. Illustratively, a display is supported by the valve body and is in electrical communication with a controller. A manual override may engage with the flow control element for manual operation thereof.

A vehicle rear-seat trunk-access locking system is provided. The system is designed to prevent unauthorized trunk access via folding down an existing rear seat of a vehicle. The system is comprised of an electronic latch mechanism that engages with a striker plate mounted to the seat structure. The latch comprises a solenoid actuator that drives a locking pin into engagement, governed by an electronic control unit receiving input from user interfaces and sensors. A multi-factor authorization sequence involving ignition activation, proximity token verification, and a manual or digital release command is required to trigger latch disengagement, with optional biometric verification for enhanced security. The system also comprises a concealed handle assembly with a spring-loaded locking plate and mechanical linkage to the latch for authorized manual override, ensuring both electronic and mechanical tamper resistance.
