In a method for permitting change of an electronic card without powering off and a communications device employing the method, the communications device includes a control module, a card connector for receiving the electronic card, and a trigger module. A first list of ticket categories may be identified which an agent has handled previously. A signal based on this known acceleration is used to calibrate the accelerometer to mitigate the effects due to at least one of sensitivity drift, D. The insert has a lower specific gravity and a higher Young’s Modulus than the front face. Using the virtual maintained temporary index allows the query optimizer to generate an access plan based on the virtual maintained temporary index, which relieves the optimizer from having to individually optimize access to each partition for partitions that share common characteristics.
