    摘要: An apparatus for cooling and containing packaged battery cells includes a first structure disposed on a printed circuit board for encasing a first battery cell, the first battery cell being electrically coupled to the circuit board, the first structure includes an external surface and an internal surface defining a first cavity in which the first battery cell is located. The apparatus further includes a first seal surrounding the first battery cell between the printed circuit board coupled to the first structure. The apparatus further includes a first thermal interface material located in the first cavity, wherein a first portion of the first thermal interface material is thermally coupled to an interior surface and a second portion of the first thermal interface material is thermally coupled to the first battery cell. The apparatus further includes a plurality of heatsink fins located on the external surface of the first structure.

    摘要: A system and method for controlling an EMC protection apparatus in a removable component. The removable component is inserted into an end product. As a result of the insertion power is applied to the EMC protection apparatus. A determination is made as to whether a power good signal is detected within the removable component. In response to a power good signal, an EMC protection device is rotated from a retracted state to an engaged state such that the EMC protection device is placed over an enclosure opening in the removable component forming an EMC seal. Full functionality of the removable component can be delayed until such time as the rotation is completed.

    摘要: A system and a method of providing electromagnetic compatibility (EMC) protection. A removable component is inserted into an end product. The removable component includes a retractable EMC protection apparatus. In response to the insertion of the removable component a shape memory alloy on the EMC protection apparatus is heated to a temperature above the activation temperature of the shape memory alloy. The shape memory alloy then changes from a first shape to a second shape in response to the heating. In response to the change in the shape of the shape memory alloy an EMC protection component of the EMC protection apparatus is inserted into an enclosure opening of the removable component.
