Voltage detecting glove

Abstract

A voltage detecting glove comprises a glove liner and an outer glove shell. A conductive antenna is disposed inside the outer glove shell but separated from the glove liner by a buffer. The antenna is connected to electronic circuitry configured to sense a voltage indicative of the proximity of the antenna to an AC electric field resulting from energized AC source, and to activate an alarm if the strength of the field exceeds a preselected threshold limit.

Description

FIELD OF THE INVENTION[0001]The present disclosure relates to a voltage detecting glove and system appointed for use by workers that service electrical equipment or are otherwise likely to encounter energized electrical circuits, and more particularly to a glove that includes an antenna and electronic circuitry capable of detecting an AC electric field and activating a signal in response to the detection of a field exceeding a preselected threshold, so that the worker can be warned of potential danger of shock.TECHNICAL BACKGROUND[0002]Contact with energized electrical circuits and equipment is widely recognized as a serious workplace hazard that can lead to serious injuries and even death by electrocution or other deleterious secondary effects, such as trauma after a fall.

AI Technical Summary

Benefits of technology

This patent describes a voltage detecting glove which includes a detection device built into the glove liner. The detection device consists of an antenna, a buffer, and voltage detecting circuitry. The antenna is placed between the glove liner and the outer shell and is designed to sense the presence of an electric field and activate an alarm if a signal is detected. The technical effect of this invention is to provide an effective and convenient way to detect potentially dangerous voltages in order to promote safety in various occupational settings.

Problems solved by technology

Contact with energized electrical circuits and equipment is widely recognized as a serious workplace hazard that can lead to serious injuries and even death by electrocution or other deleterious secondary effects, such as trauma after a fall.

In some instances, the hazard is immediate and apparent, but in others, the danger may be indirect.

For example, there is an immediate and recognizable hazard for electricians or other workers who deliberately come into direct contact with actual electrical equipment while installing or repairing it.

In theory, the hazard can be removed by de-energizing the equipment, but unrecognized faults or human error all too often cause a worker to believe the work can safely proceed, even though there is still a shock hazard.

In addition, workers can inadvertently come into direct contact with energized circuitry or be exposed as the result of indirect contact by cranes, forklifts, ladders, or other like workplace equipment or tools through which current is conducted to the user.

Although high voltages are often perceived as more dangerous, a sustained electric shock from an ordinary 120 V / 60 Hz source can easily result in ventricular fibrillation, since the shock intensity may exceed the let-go threshold, while not delivering enough initial energy to propel the victim away from the source.

However, in either of these situations, the testing is typically done once at the beginning or at irregular times during the course of a job that are not correlated with the worker's continuing activity.

Such testing, carried out prior to a worker's entry into an area or the initiation of a given job activity, can often avert danger.

Nevertheless, a hazard could arise later and without the worker being notified.

In a complex job site, the activities of other workers could conceivably energize circuitry without knowledge of the entire workforce, so that activity that had been cleared by preparatory testing might later become dangerous.
