A media content receiving device, such as a set top box, includes a chassis that incorporates a heat bridge, a heat shield or both. The heat bridge may take the form of a structural wall coupled to, but preferably integrated with, the chassis to facilitate conductive heat transfer into a chassis panel. The heat bridge may be configured to receive heat radiated from a chip having a die to be cooled. The heat shield may take the form of a wall-type structure protruding from a chassis panel. For example, the heat shield may extend from a top panel of the chassis in a fin-like or flange-like manner to provide a thermal barrier between adjacent electrical components arranged on a circuit board. While the heat shield protects the adjacent component from potential thermal damage or degradation, it may also operate to transfer heat into the chassis.

Systems and methods are operable to detect infrared (IR) signals at a media device. Exemplary embodiments include a media device configured to receive media content; at least one IR detector residing in the media device, and configured to receive a portion of IR signals emitted from a remote control; and a cover lens disposed in a portion of an enclosure of the media device. The cover lens has a first cover lens portion configured to receive the IR signals emitted from the remote control and is configured to transmit a first portion of the received IR signal to the IR detector when the media device is horizontally oriented, and has a second cover lens portion configured to receive the IR signal emitted from the remote control and is configured to transmit a second portion of the received IR signal to the IR detector when the media device is vertically oriented.

Apparatus, systems and methods for detecting infrared signals at a media device configured to be positioned in different orientations

A media device includes at least one piezoelectric fan selectively located to draw or urge air past one or more electrical components, such as an integrated circuit chip. Preferably, the piezoelectric fan is located within a channel milled or otherwise formed in the chip, however the fan may be located proximate the channel yet in fluid communication therewith. The piezoelectric fan operates to convectively cool the electrical component and may also prevent heat that has been generated by the electrical component from moving toward another electrical component within the media device. Thus, the configuration and location of the piezoelectric fan may advantageously cool one component while preventing heat energy from building up around one or more other components mounted nearby.
