Indicators and methods of indicating are disclosed. Intended primarily for use with medicine containers, the devices typically indicate the number of doses of medication ingested or remaining to be taken by a patient during a particular period. These devices additionally provide tactile assistance to patients in appropriately repositioning the indicator arms and, when used correctly, may reduce the possibility of patient overdose by restricting improper attempts to advance the indicator arm.

Disclosed herein is an improvement of an indicator such as a speed meter, a tachometer, or the like for use in a motor vehicle. The indicator comprises a scale plate having a pointer rotatably mounted thereon, indicia provided on the scale plate and containing fluroescent brigthener, the indicia indicating a specific value in cooperation with the pointer, a single ultraviolet light source for illuminating the indicia, and technique for equalizing the brightness of the indicia. The equalizing tec...

This invention relates to an indicating device for the navigation of vehicles along power cables, especially of ships along underwater cables, wherein a system of coils is mounted on the ship, which coils are adapted to sense the magnetic field surrounding the cables.

A composite indicator for obtaining a digital or alpha numeric readout as well as a dial type readout with provision for adjusting the output by dialing in certain corrections.

In an indicator device, the usual pointer is replaced, in accordance with the invention, by a path of moving light which comprises an illuminatable path. The path is illuminatable from one end to the other in such a manner that, when a portion of the path is illuminated, then all of the path from one end thereof to the portion is illuminated while the remainder of the path, from the other end thereof to the portion, is not illuminated. The illuminatable path preferably comprises a plurality of i...

A wetness indicator including a pH indicating agent may be a single layer or a multilayer composite. One or more layers of the composite may be used to promote or inhibit environmental fluid contact with the pH indicating agent dispersed within at least a portion of a layer thickness. Fluid travel through the layer thickness may be achieved by layer microporosity and/or addition of fluid regulating additives to the layer. The layer or layers may be polymer layers, ink layers, fibrous layers or c...

An operation indicator is provided to indicate the open/closed status of device, e.g. a circuit interrupter operable between open and closed operating positions. The operation indicator includes two indicator members having cooperating interleaved or interlaced construction such that a relative small operating stroke of the operable device results in relatively larger open and closed symbol and indicating surfaces.

A detectable indicator (10) formed on a body (18), the indicator (10) comprising a deformable element (12), a safeguard (14) at least partially surrounding the deformable element (12) and an area (16) in the safeguard allowing access to the deformable element (12).

A humidity indicator includes a first film (F1) covering a surface of a humidity-determining plate (B), and a second film (F2) covering a back of the humidity-determining plate (B). A flat air layer (Au) is formed at least between the first film (F1) and the surface of the humidity-determining plate (B), so that the entire surfaces of humidity-determining faces (M1 to M4), to which cobalt chloride (CO) is exposed, face to the air layer (Au), and a plurality of small holes (H) are formed at dista...

A status indicator indicates an operating state, including an electrical malfunction, of an electrical load that is located and controlled from locations remote from a monitoring location.
