| A sensing device for determining the amount of liquid in an oil crankcase of a vehicle. A hollow dipstick, closed at one end and having a metering hole therein, is inserted into the crankcase of a car. The other end of the dipstick is connected by flexible tubing to a suction bellows and a sensing bellows in a sensing module. The suction bellows and sensing bellows are linked together and to the dipstick by branches of a T-tubing. An opposed end of the suction bellows is connected to a piston of a solenoid. The sensing bellows is mounted to move in response to the amount of oil suctioned into the dipstick. An electrical circuit is formed between a push-button, a solenoid, ground and the car battery, such that when the push-button is closed, the solenoid becomes excited, drawing in the piston to thereby expand the suction bellows. Expansion of the suction bellows draws oil into the dipstick. An electrical circuit coupled to the sensing bellows indicates if oil is sampled by the dipstick. | ||||||

| Methods and systems are providing for improving engine coolant level estimation to reduce engine overheating. The level of fluid in a coolant overflow reservoir is inferred based on the fluid level in a hollow vertical standpipe fluidically coupled to the reservoir at top and bottom locations, while the fluid level in the standpipe is estimated based on echo times of an ultrasonic signal transmitted by a sensor positioned in a recess at the bottom of the vertical standpipe. Engine power is limited differently based on distinct coolant level states determined based on a change in level of coolant in the reservoir over a duration. | ||||||

| A device, comprising a float, basin, and basin cover, is removably attached to interior rungs of a dishwasher via clip-hooks, and stabilized with a tongue arm, design features of the clip-hooks, and the cooperating portions of the basin or cover. The float rises to a completed water cycle ‘clean’ position as basin fills with water. The basin may block view of the float when in a ‘dirty’ position. The float provides visual indication of a completed water cycle, and therefore ‘clean’ dishes, after rising as a result of water introduced into the basin via holes in the cover. Water that was introduced into the device automatically leaves the chamber via one, or more, discharge holes/openings in the basin, while the float remains in the ‘clean’ position because of one or more retainers; e.g., magnetic force from one or more magnets. Retainers can generated and communicate position status to a smartphone. | ||||||

The mounting frame is mounted to the vessel using spacers forming an open gap between the mounting frame and vessel. The open channel and gap minimize the transfer of heat from the vessel to the level gauge. The passage of a float with a magnet on the liquid in the vessel rotates the flags. | ||||||
