Latest Patents
One of his latest patents is titled "Power management fault strategy for automotive multimedia system." This invention involves a multimedia/personal computer-based system designed to operate information, communication, and entertainment devices in a mobile vehicle. It employs a power management strategy that reduces power consumption and boot-up time, facilitating the use of a complex instruction set computing (CISC) processor system. The system includes a power management fault strategy that detects fault conditions and restores proper operation without user intervention. A low power microprocessor off-board the main motherboard switches a plurality of regulated voltages to the main motherboard and other devices, ensuring efficient operation.
Another significant patent is "Automotive computer system and method whereby responsive to detecting engine cranking main processor enters a suspend mode and current state of devices are stored in volatile memory." This invention addresses the challenges faced during engine startup when battery voltage decreases, potentially harming electronic devices. The system utilizes a low power microprocessor off-board the main processor board to switch a primary voltage regulator off, reducing power requirements. The main processor board stores the state of predetermined peripheral devices in volatile RAM before turning them off, entering a suspend mode until a wake-up signal is received.
