Abstract: An oven door interlock system configured to selectively block a switch based on a position of an oven door may include a switch, a reference hinge attached to the oven door, the door movable between an open position and a closed position, and a locking mechanism connected to the switch via a rod, the locking mechanism including a hinge receiver connected to the reference hinge attached to the oven door, the reference hinge including a cam configured to move along a first axis in response to actuation at the oven door and to affect movement of the rod along a second axis perpendicular to the first axis on a position of the oven door to selectively block access to the switch when the oven door is in the open position.

Abstract: The disclosure generally relates method, system and apparatus to prevent denial of service (DOS) attacks on PCIe based computing devices. In an exemplary embodiment, an independent register is used in combination with a filter driver and additional logic to form an integrity check for power down instructions. An exemplary system includes a register circuitry corresponding to the IP device, the register circuitry having a designated storage bit to indicate an unlocked state of the register; a filter driver to receive a first power state transition request when the IP device is idle after a predetermined period, the power state transition request defining a timeout period; a controller to change the power state of the IP device to the unlock state; a decision logic to receive and authenticate a second power state transition request in response to validation of register circuitry being unlocked.
