Abstract
A test device includes a pair of test probes (21 and 22) which are manipulated onto a succession of test sites (11, 13 and 16) formed on a complex circuit board, and the operator is visually apprised of test results without loss of eye contact with the test sites. Visual appraisal is provided by a small light emitting diode (46) which is activated in accordance with the probed test results. The diode is mounted on the operator's safety glasses (58) and is of such size as to be not discernible when positioned inside the normal focal point of the operator's eye, but a glow is discernible when the diode is operated upon a particular test condition being ascertained by the test probes.
Claims8
A test device for attachment to eyeglass frames, which comprises:
- a light emitting diode;
- a clip for attachment to the eyeglass frames;
- means secured to the clip for supporting the diode in close proximity to a lens in the frame and inside the normal focus distance of a user's eye;
- a pair of electrically conductive probes;
- and
- a test device interconnected between the probes and the light emitting diode for operating the light emitting diode upon the probes ascertaining a predetermined test condition.
An attachment for a test operator's safety glasses, which comprises:
- a pair of thin, relatively stiff wires which are not readily discernible when positioned within the focus of the eye of an operator;
- a light emitting diode of a size that is not readily discernible when positioned within the focus of the eye of the operator, said diode being secured to the first ends of said wires;
- means for securing the other ends of said wires to the frame of the operator's safety glasses to position said diode within the focus of the eye of the operator;
- and
- means responsive to a test result for generating a signal and applying said signal to said wires to operate said diode to apprise the operator of the test result.
A test result indicator for use with safety glasses, which comprises:
- a test device for indicating a test condition and accordingly generating an electrical signal;
- a light emitting diode of a small size that is not readily discernible when positioned inside the normal focus of a wearer of the safety glasses;
- means attached to the safety glasses for supporting the light emitting diode within the field of vision of the wearer but inside the normal focus of the eye of the wearer;
- and
- means for applying the signal from the test device to energize the light emitting diode to produce a glow that is discernible by the wearer.
