Shinjiro Yamada is an inventor associated with Tokorozawa, Japan. His patent work includes approaches to reducing power consumption in information-processing devices while maintaining responsive handling of interruption requests. He is credited with 3 patents.

Latest Patents

Yamada’s listed patents focus on timer systems that manage waiting periods before scheduled events and system calls.

“Information processing device which specifies a waiting time until execution of a given event and makes a system call” describes a device with two timer circuits: a first timer operating on a longer cycle and a second timer operating on a shorter cycle. The device tracks the time remaining until an event and the next interruption request. It uses the first timer for longer waits and applies the shorter-cycle timer when the remaining wait falls below the first cycle, aiming to reduce power consumption without slowing interruption responses.

“Power consumption reduction and quicker interruption response in an information processing device utilizing a first timer and a second timer wherein the second timer is only conditionally activated” describes a related approach. It likewise uses a longer-cycle first timer and a shorter-cycle second timer, activating the second timer conditionally to manage shorter remaining waits while balancing energy use and interruption response speed.
