Title: The Innovative Mind of Mark Hirst
Introduction
Mark Hirst is a notable inventor based in Boise, ID (US), with a remarkable portfolio of 9 patents. His work primarily focuses on advancements in electrical control systems and operational sequencing in devices.
Latest Patents
One of Hirst's latest patents is the Integral Half Cycle (IHC) control. This invention allows for the control of power to an electrical device using a phase control that adjusts the cutoff phase of an alternating current (AC) electrical signal. The power delivered to the device is increased to an operational level through this phase control, while an integral half cycle control maintains this power level by selectively removing several half cycles from the AC signal. This ensures that the remaining half cycles operate outside a range of sub-harmonic frequencies.
Another significant patent is the Parallel/Serial Operational Sequencing. This invention describes a printer system that includes an engine control unit and an image processor unit, each connected to various sub-systems. The network unit monitors network packets while the system is in sleep states. Upon receiving specific predetermined packets, the network unit signals the image processor unit to awaken, allowing for efficient management of the printer's operational states.
