Latest Patents

One of Ikeno's latest patents is a distance measuring device. This device features a pixel G that includes sub pixels Po and Pe arranged in a row direction. The floating diffusion parts Fdto and Fddetect charge quantities that relate to reflected modulated light Lb, which is delayed in start by every half of a period of emitted modulated light La. Additionally, a binning group Gv is configured by an array part where the two sub pixels Po and the two sub pixels Pe are adjacent to each other in a row direction.

Another notable patent is a video projection apparatus capable of operating at optimum resonant frequency along with its controlling method. This apparatus includes a light source and an optical deflector that has a mirror for reflecting light to project a view field. It also features an actuator for rocking the mirror and a sensor located near the actuator. The control unit generates sine-wave and cosine-wave voltages applied to the actuator, calculates convolutions with the sensor's sense voltage, and sweeps the frequency of the voltages to define the resonant frequency when the radius component is at its maximum.
