He has made significant contributions to the field of opto-electronic circuits, holding two patents that showcase his innovative spirit and technical expertise. His work has implications for various applications, particularly in the realm of electronic devices.
Latest Patents
Engstrom's latest patents include a "Temperature Compensated Opto-Electronic Circuit and Mouse Using Same." This invention features a temperature compensated opto-electronic circuit structure that includes an emitter connected to one input of a comparator to provide a reference signal. A detector signal is applied to another input terminal of the comparator, and the output is determined by the difference between the reference signal and the detector signal. As the temperature of the opto-electronic circuit fluctuates, the reference signal is automatically adjusted due to temperature-related forward voltage changes of the emitter. Another notable patent is the "Method for Producing Opto-Electronic Circuit Using Laser-Trimming Device." This method involves producing opto-electronic devices, such as opto-mechanical mouse devices, by adjusting a detector signal after connecting a detector and emitter to the remaining circuitry. The process includes both a rough adjustment step and a fine adjustment step to ensure optimal performance.
