Abstract: An electronic circuit for energizing an electric lamp associated with an alarm clock. Alarm circuitry within the clock energizes an electronic flasher that delivers a control signal to a bidirectional switch means in an A.C. circuit containing the lamp. The switch means triggers a two direction silicon controlled switch means in the lamp circuit. The lamp provides an optical alarm that can be used as a wake-up signal by persons who are deaf but who can see.

Abstract: A telephonic therapy training device usable by speech-impaired persons and/or hearing-impaired persons to improve their telephone usage skills. The device is a "learn-by-doing" device wherein the instructor and each student are provided with individual handsets, each of which includes a microphone and a speaker (receiver). Each voice signal is sent through a microphone into an individual amplifier that transmits an amplified signal to an opposite party receiver in the individual handsets. The training device operates on regular household current; the use of commercial telephone lines is avoided in order to escape telephone service fees.
