Latest Patents
One of Richard's latest patents is the "Photovoltaic Optoelectronic Switch." This invention features an optoelectronic switch designed to switch an input signal using two PIN diodes connected in series with opposed polarity. The switch includes an input signal choke that presents a high impedance to the input signal while allowing a low impedance to the PIN diode bias. Additionally, a photovoltaic cell is integrated to generate the necessary bias for switching the diodes between conductive and non-conductive states based on the presence of optical energy from a light source.
Another notable patent is the "Optically Activated Back-to-Back PIN Diode Switch Having Exposed." This optoelectronic switch comprises two PIN diodes connected in series with opposed polarity, with their intrinsic regions coupled to a light source. This design allows both diodes to remain in a conductive state while the light source is active and switch to a non-conductive state when the light source is off.
