A chemical indicator of an aurin moiety in a substrate to detect the presence of an oxidizing agent.

The present disclosure relates to a restriction indicator for an air cleaner system of an internal combustion engine. The restriction indicator includes a housing divided into first and second chambers by a diaphragm. A signal member is connected to the diaphragm. The signal member is moveable along an axis between a reset position and a first indicator position, and defines an axial opening within which a first retaining shoulder is located. A guide member is provided for guiding the signal mem...

This invention includes a combustion engine fuel level indication system operable at 10 mA or lower and without any contact resistance buildup. The present system utilizes a noble metal ink formulation for both contacts of resistive path and a conductive path. The resistive and conductive paths each having angled conductor lines which reduce the overall volume requirement for the noble metal ink composition used to make the paths. The invention also includes a wiper contact having spaced apart p...

The electric probe is connected to the alarm indicator light and the carbon brush has a contact portion on its outer surface which when the brush is worn and need to be changed is electrically connected to the alarm indicator light through the electrical probe to ...

A medication dosage indicator having two portions, a body portion and a cap portion. The body portion includes a circular top wall and a plurality of raised indicator tabs spaced apart in a circular fashion that have indicia corresponding to the day of the week or other unit of time. The cap portion includes a circular upper wall with a plurality of apertures sized and spaced apart to fit in a mating relationship with the indicator tabs.

The present invention relates to a use indicator apparatus having a power-sensing mechanism and an indicator. The indicator includes a first state and a second state wherein the indicator is maintained in the first state until a required amount of power is applied to the sensing mechanism. Upon reaching the required amount of power, indicator switches from the first state to the second state.

Wind indicator apparatus for indicating air flow comprising: a direction pointer, including a vane member, for providing a visible indication of air flow direction; pivoting means including a fixed portion for coupling to a sailing craft and a pivotable portion able to pivot with respect to said fixed portion and with which said direction pointer is entrained for movement therewith; and a counterbalance extending from said pivotable portion of said pivoting means and arranged to move therewith, ...

A system and method for indicating the service status of serviceable elements of a subassembly stores the service status in a memory using a host controller. When the subassembly is removed from the host controller, the memory may be accessed using a second circuit and separate power supply, and indicators may be illuminated to indicate the service status of the elements.

A boat indicator enables a user to easily read engine speeds for boats which can switch between a low-speed trolling mode and a normal running mode at speeds higher than the trolling mode speed. The boat indicator includes an engine speed indicating section for indicating engine speed. The engine speed indicating section is adapted to switch between a normal mode display for indicating the engine speed over a relatively large range when the boat is in the normal mode and a trolling mode display ...
