A capless multiaxial screw fixation assembly, including: a screw having a threaded portion and a screw head portion positioned at one end thereof; and, a retainer having a first end, a second end opposite the first end, and a bore for receiving the screw threaded portion so that the screw head portion is seated therein. One method involves searching one or more client locality tables for the signature of a data unit. In the sourcedrain regions, a region shallower than a region where the suppression impurity is distributed is made into silicide, so that a silicide film is formed in the sourcedrain regions. Such methods and systems then combine the plurality of phase modulated signals into a combined signal, generate expected signals, and cross-correlate the combined signal with the expected signals to form correlation signals. Based in part on the passenger data received, elevator controller provides elevator dispatch, elevator door control, and security functions.
