A locking system including a lock box and a locking bar. In one embodiment, a method for allocating resources to a multimedia conference includes receiving a request from a potential participant to join the multimedia conference and dynamically assigning the request to one of a plurality of media servers serving the multimedia conference. The +\u2212 1st order scale light beams are reflectively diffracted back from scale grating to return to the mirrors, and are then reflected to converge back toward the light source and a set of adjacent fiber-optic receiver channels. Additionally, the antenna is adopted to increase the linear radiation bandwidth by utilizing the well, and transceives a circularly-polarized electromagnetic wave by utilizing the Wilkinson power divider. The circuit element provides the possibility of real time configuration between various logic functions with a minimum of transistors and wiring. Obtaining timely confirmation that the host processor has received the scan successfully leads to increased confidence in, and acceptance of, the cordless hand-held scanner.
