With an impressive portfolio of 42 patents, Davis has made substantial advancements in caller identification and telephone signaling technologies. His work exemplifies the innovative spirit that drives the telecommunications industry forward.

Latest Patents: Among his latest innovations is a **telephone caller screening device**. This device operates with a pre-existing telephone line and an installed telephone device. In one mode, it selects and stores caller ID information from incoming calls for comparison with caller-entered data, determining whether to alert users. In another mode, it generates an off-hook condition to suppress the ring signal of incoming calls, preventing audible ringing and instead generating an alerting signal when the caller's identification matches the stored data. If the caller's data is invalid, or the recipient does not respond, the call is diverted to a message device.

Another key patent is the **telephone ring signal detector**. This device connects to a telecommunications line to detect and discriminate the first telephone ring signal from other signals. It generates event signals, receives incoming signals, and compares signal characteristics to predetermined limits to validate the ring signal. This ensures accurate detection and response to telephone ringing, enhancing the efficiency of communication systems.
