A food contact device including a handle member with a first end and a second end. Then, gradient based images at M scales and N orientations are generated from the pre-processed facial image. The alternate transceiver node transmits a pilot signal at a second frequency. The stylus terminates at the contact end in a received portion, attached to the disc by a receiving portion formed thereon. An example method may comprise: detecting, by a computer system, a memory pressure condition on a first node; invalidating a page table entry for a memory page residing on the first node; copying the memory page to a second node; and updating the page table entry for the memory page to reference the second node.
