Abstract: A combination multiplexer and tristate circuit. A multiplexer circuit may be configured to receive at least a first data input and a second data input, which are selected by at least a first select signal and a second select signal, respectively. A first circuit is configured to provide an output to an output node responsive to the data input that is selected by the corresponding select signal being active. The multiplexer circuit may further use a tristate circuit, which is also coupled to receive the first select signal and the second select signal. If neither the first select signal nor the second select signal are active, then the tristate circuit is configured to prevent the first circuit from providing an output to the output node.

Abstract: The invention further includes a method and system for encouraging employees and employee managers to use the time keeping and expense entry server for entering and approving time entries. Thus, the employee is coupled to produce final time entries to the TKET server wherein the TKET server is coupled to produce the final time entries to an employee manager for approval. After receiving approval, the TKET server generates approved time entries to an accounting department terminal, and if appropriate, to a contract employer terminal so as to trigger invoicing and payment for the employee's labor. The TKET server also generates an award, if appropriate, to the employee of his manager for following specified time entry procedures.

Abstract: A 1xEVDO network includes an access terminal that generates an access terminal ID as a part of the call setup signals it generates when setting up a data call. In order to determine whether the user ID is authorized to access the 1xEVDO wireless data network, a AAA server is formed to include a table that identifies authorized access terminals, by access terminal ID, for access to the 1xEVDO wireless data packet network. In one embodiment of the present invention, the wireless access terminal also is formed to perform an algorithmic calculation upon a received random number and to produce the results to an access network controller. The AAA server, then, is formed to determine whether the results produced by the access terminal are correct. In one embodiment of the invention, the AAA server is formed to perform the same algorithmic calculation.
