A combination dip and cake holder and punch bowl is readily configurable between any of three configurations. The system has an ultra-compact construction, ideally suited for space-constrained retail scanning environments, and generates a 3-D omnidirectional laser scanning pattern between the bottom and side-scanning windows during system operation. The invention further provides a method of making a carbamate-functional polymer and carbamate-functional polymers made by the claimed method. After the trap is provided software monitors the fill state of the compressed memory. The blocking mode may have a higher latency but may allow the receiving thread to enter a sleep mode or perform other activities. An impurity segregation layer on these regions is removed, and a film of a metallic material is thereafter formed on the regions and is heat-treated, thereby forming a silicide film on the semiconductor layer.
