Abstract: The present invention relates to a permeation test cell for permeation testing of materials against chemicals. The permeation test cell comprises an upper body provided with first vents and a lower body provided with second vents, for passing a first and a second gaseous stream. A perforated Polytetrafluoroethylene (PTFE) grid on the sample support plate is placed underneath the test sample to allow passage of the contaminant to the sorbent tube. A test sample with a contaminant is disposed in the permeation test cell. The second vent is configured to be attached to a sorbent tube for accumulation of contaminant permeating through the test sample. The permeation test cell is configured to receive a weight on the test sample for forcing permeation of the contaminant through the test sample.

Abstract: A method and an apparatus are provided for powering off a portion of a memory of a mobile system. The apparatus may store data within a memory of the apparatus. The apparatus may copy a first portion of the data stored in a first portion of the memory into a second portion of the memory so that the data is stored in the second portion of the memory. The first and the second portion of the memory may be the same memory type. The disclosure discusses various triggering events that may cause the apparatus to copy the first portion of the data stored in the first portion of the memory into the second portion of the memory. The apparatus may then turn off the first portion of the memory. In this manner, the memory consumes less power when storing the data during a low power mode.
