发明名称 Visual Alert Timing Device
摘要 I have invented an improvement to a basic timer device that allows for a visual alert mode and pray that Letters Patent may be granted for the improvement idea for a visual alert timer, as set forth in the patent application specification which uses electrical power, however the device can be powered by any source and can function as both an auditory and/or a visual alert device. I invented this idea to improve the timer on 20 Feb. 1989 as an assistive device for the Deaf; however this improvement idea can be used to aid any individual needing a visual alert while working in a noisy work environment at home or in the workplace.
