A temperature indicating material of the present invention includes at least an electron donating compound, an electron accepting compound, a reversible material causing reversible transformation between crystal and amorphous states, or reversible transformation between phase separation and non-phase-separation, with respect to a part or all of the composition system; and a temperature characteristic controller having a solid-state in room temperature and at least a part of the temperature chara...

The present invention relates to an illuminating or indicating device, including at least two light sources, each light source being associated with a first optical system. According to the present invention, each first optical system, at finite distance, forms a real image of the light source, the images of the light sources being coincident at a common point constituting a secondary source, and a second optical system having an optical axis passing through the secondary source forms an illumin...

An irreversible temperature indicating paint comprises 29 wt % to 37 wt % cobalt zinc silicon blue phenacite and a frit, 35 wt % to 45 wt % acrylic resin and 20 wt % to 30 wt % silicone resin excluding solvent. The solvent comprises a mixture of 80% 1-methoxy-2-propanol and 20% dipropylene glycol monomethyl ether. A particular irreversible temperature indicating paint comprises 34.9 wt % cobalt zinc silicon blue phenacite and a frit, 42.5 wt % acrylic resin and 22.6 wt % silicone resin excluding...

A miter angle indicating tool includes three members that are pivotally attached. The miter angle indicating member is adapted to display the miter angle in or around a corner requiring a miter joint, or to display the bisecting angle of an object. Once the required angle is displayed, the indicating tool can be used to either transcribe the angle onto the material that will form the miter joint or as a jig to set the cutting apparatus to the proper cutting position. In the preferred form of the...

A pulse oximetry sensor having a temperature indicator and a method of operating such a sensor to visually indicate to an operator the temperature of the sensor and hence a measure of the temperature of the tissue location to which the sensor is attached. In one embodiment, the temperature indicator is a color changing liquid crystal temperature monitor. The liquid crystal temperature monitor includes a number of segments, each of which is activateable within a predetermined temperature range to...

An indicating instrument for a vehicle includes a dial plate, a light modulation member disposed on the dial plate and a controller for controlling the light transmissivity. The light modulation member has variable light transmissivity, and the controller changes the light transmissivity according to a condition of the vehicle when operated.

A system for transforming the movements of at least one joint of a user into control signals for a computer. The system includes a sleeve for putting on over the joint and a movement sensor fixed to the sleeve for the sensor to be placed and held in the hollow of the joint. The sensor is an on/off sensor that is directly subject to the movements of the sleeve in the hollow of the joint.

A method and apparatus for determining fastener axial loading includes a fastener insert having an arched bottom surface, which deflects correlative to the level of axial loading. A load indicating mechanism determines axial loading by measuring the amount of deflection experienced by the arched insert. In addition, the arched insert stores elastic energy which is added to the overall elastic energy of the fastener, thereby aiding the fastener integrity during use. The system comprises a zeroing...

A method and apparatus for a signaling device includes an audio device that generates either or both an audible output such as a tone and a voice. The output is based upon a status level. The signaling device further includes a light emitting diode (LED) strobe that illuminates in a variety of colors, where the illumination of a specific color is based upon the status level.
