Latest Patents

Sakai's latest patents include a "Scanning Image Display Device and Method of Controlling the Same." This invention features a scanning image display that comprises a light source, a light detector, a scanning section, a storage section, a current controlling section, a reference current section, a sweep section, and a change section. The light detector is responsible for detecting the laser light emitted from the light source, while the scanning section scans this laser light. The current controlling section regulates the laser light by supplying current to the light source. The storage section is designed to store a reference current value, a reference light output value, and a gamma table. The reference current section provides the reference current value to the current controlling section. The sweep section sweeps current values supplied to the current controlling section to determine a current value where the detected laser light corresponds to the reference light output value. Finally, the change section modifies the gamma table based on the current value obtained by the sweep section.

Another significant patent is the "Multipolar Resolver." This invention eliminates the need for the traditionally essential coil on the resolver rotor by incorporating a center coil on the stator. It features 5n or 3n rotor poles and 4n stator poles, where n is a positive integer. Sine and cosine coils are alternately wound on the stator poles, simplifying the construction of the multipolar resolver.
