Latest Patents

One of Shyu's latest patents is an optical engine for fingerprint readers. This innovative optical engine features a one-piece optical prism that serves the dual purpose of a prism and lens. This design replaces traditional optical engines, which typically consist of a right-angle prism and a lens. The compact nature of this device allows for easier modularization. Additionally, the complete light path between the fingerprint and the sensing device enhances the signal-to-noise ratio (S/N), thereby improving reliability and stability. The design also incorporates an LED light source around the optical prism and features an ergonomically designed arched concave with a diameter of 120 mm, which provides clearer fingerprint images.

Another notable patent is a lens module that includes a lens set, a rotation base, an outer case, elastic members, a driving device with a stepping motor, and a base frame. The lens set is securely fixed within the rotation base, which is elastically arranged between an upper and lower case. The stepping motor drives the rotation base to rotate clockwise or counterclockwise. The circular bottom surface of the rotation base features a series of sloped grooved surfaces that facilitate focusing travel. This innovative design allows for easy assembly and disassembly of the lens module without causing damage.
