Embodiments of the present disclosure provide an optical encoder that has magnetic elements embedded in a shaft or shaft of the optical encoder. Further, the optical encoder is hermitically sealed and is configured to rotate based on a magnetic field between the optical encoder and an actuation member.

An electrical power and/or electrical signal transmission system for transmitting electrical power and/or electrical signals from a location on a first side of a metallic wall to a location on a second side of the metallic wall includes a transmitting apparatus having an electrical source and a first transformer. A receiving apparatus has a receiving module for receiving electrical power and/or electrical signals and a second transformer. First and second ends of a primary winding of the second transformer are electrically connected to respective spaced locations on the second, opposite, side of the metallic wall for picking up electrical power and/or electrical signals from the metallic wall. The receiving module is electrically connected to a secondary winding of the second transformer to enable electrical power and/or electrical signals to be transmitted from the electrical source to the receiving module.

An automatic water sampler is disclosed. The automatic water sampler of the present invention comprises: a driving unit operated according to the pressure measured by a pressure sensor; a driving magnet approaching a driven magnet according to the operation of the driving unit; and a first wire unlocked by a control rod according to the movement of the driven magnet. The present invention can provide an automatic water sampler, which improves inaccuracy due to conventional interference of an ocean current, flow velocity, and the like, and manual water sampling by depth by automatically sampling water at the correct depth recognized through a pressure sensor, thereby enabling reliability and accuracy of a sample to be ensured and sampling expenses to be remarkably reduced.

A differential pressure indicator includes a multi-polar driving magnets train clamped on a piston pin that moves in response to the changes in pressure conditions, thereby driving a multi-polar follower magnet carrying an indicating member, to move across a scale for a total angular range of 90° to 270°. The exact angular displacement of the follower magnet per unit linear displacement of the driving magnets train is decided by varying the relative magnetic strengths of the driving and follower magnets or by varying the spacing between adjacent magnets of the driving magnetic train. Further, magnetic flux of an auxiliary magnet fitted on the piston pin at a 90° orientation relative to the driving magnet train is utilized for actuating a magnetic switch in the switch assembly.

A riding lawn mower includes a chassis, a power output assembly, a walking assembly, a power supply device, a control module, and an operating apparatus. The operating apparatus includes at least one bracket, an operating lap bar assembly, a pivoting assembly, and a position detecting module. The pivoting assembly mounts the operating lap bar of the operating lap bar assembly on the bracket. The operating lap bar can rotate around different positions in a first direction F1 and/or a second direction F2. The position detecting module includes a magnetic element and a magnetic sensor. The magnetic element is provided on the pivoting assembly or the bracket and the magnet sensor is spaced from the magnetic element so that the magnetic element and the magnetic sensor can generate a relative movement for detecting the position of the operating lap bar in the first direction F1 and/or the second direction F2.
