Latest Patents
Higemoto's latest inventions include the following:
1. **Wireless Key System and Key Location Determination Method**: This innovative system and method are designed to determine whether a wireless key is positioned inside or outside a main body. It employs a communication device that transmits a wireless signal through both an inner antenna and an outer antenna, which possesses different directivities. The system measures the wireless key's movement direction upon receiving the signal and identifies the antenna with the strongest signal as the first antenna. By selecting a second antenna with a matching directivity to the inner antenna, the system can ascertain if the wireless key is inside the main body based on the respective signal levels.
2. **Analog Semiconductor Integrated Circuit and Method of Adjusting Same**: This patent introduces an analog semiconductor integrated circuit equipped with an analog circuit, a PMOS transistor, and a bias adjustment circuit. The PMOS, part of an open-drain output system, is linked to an internal node within the analog circuit. The bias adjustment circuit allows for the modification of the bias current depending on the number of fuse disconnections. This method optimizes the bias current flow to the output section of the analog LSI by evaluating varying threshold voltages and measuring voltages under fixed current conditions.
