Abstract: Embodiments described herein provide techniques for securely validating firmware on a device using certificates and providing a mechanism for deprecating select certificates when a traditional certificate authority is unavailable or otherwise cannot be used. When a first firmware package is installed on the device, a first certificate in a first secure memory location is associated with an active status. Responsive to validation and installation of a second firmware package on the device, a second certificate in a second secure memory location on the device is associated with an active status. During a boot-up operation on the device, embodiments determine to use the second certificate to validate the second firmware package by starting at a predefined secure memory location and scanning backwards until a status of active is identified. The second firmware package on the device is then validated using the second certificate.

Abstract: One embodiment relates to an electrical component cooling system that facilitates convectional air flow. The system includes a set of electrical component boards, an inlet, an outlet, and a housing. The electrical component boards each include a plurality of electrical components and are oriented vertically. The inlet is disposed on the housing below the electrical component boards, and the outlet is disposed on the housing above the electrical component boards. The housing substantially encases the electrical component boards and further includes a plenum. The inlet enables ambient air to flow into the plenum disposed within an internal region of the housing. The plenum horizontally directs the air to locations vertically aligned with the regions between the electrical component boards to facilitate convectional air flow in the vertical direction. Heat transfer occurs between the electrical component boards and the air as it flows across the surfaces of the electrical component boards.

Abstract: One embodiment of the present invention relates to a noise containment and vibration isolation system for integrated audio/video electrical components. The system includes a housing, an inlet, an outlet, an electrical component board, a noise containment system, and a mechanical isolation system. The noise containment system includes encasement of the electrical component board and baffling of the inlet and outlet air vents. Noise containment obstructs direct ambient air flow paths within the housing, thereby also impeding and obstructing the transmission path of air-based sound waves. The mechanical isolation system includes positioning dampening members between the housing and the electrical component board. The mechanical isolation system further includes positioning a dampening member between the housing and a supporting surface. Mechanical isolation minimizes the transmission of vibration-based sound waves between mechanical coupling points.
