With a total of 3 patents to his name, Riggs has demonstrated a commitment to innovation and advancement in his field.

Latest Patents

One of Riggs' latest patents is for a digitally controllable analog switch. This invention involves an operational amplifier that generates an output analog signal at an output node, which is representative of an analog signal fed to the non-inverting input of the operational amplifier. A controllable switch connects the output of the operational amplifier to the output node, and the signal at the output node is fed back to the inverting input of the operational amplifier. The controllable switch responds to a digital logic control signal, completing the circuit path between the operational amplifier and the output node to generate the output analog signal. Additionally, a plurality of such operational amplifiers can have their feedback paths connected at a common output node.

Another significant patent by Riggs is the anticipatory servo controller for controlling magnetic tape movement. This invention features electronic circuitry that regulates magnetic tape movement during the loading of a predetermined length of tape from a supply spool into a tape cassette. The tension of the tape along its path is controlled by a pair of vacuum column tension members, providing different tensions at the supply and take-up spools. The driving member interposes the two vacuum tension members to regulate tape movement, while the electronic circuitry drives the take-up spool, the supply spool, and the interposing driving member, formulating drive signals based on the length of tape contained at the separate tension members.
