Abstract: A method of controlling a hot wire anemometer (HWA) of a non-nicotine e-vaping device includes controlling, by a first PID controller, a level of power applied by the non-nicotine e-vaping device to the HWA based on a temperature of a heated element of the HWA and a temperature setpoint; generating a puff detection signal indicating whether or not a puff is currently occurring with respect to the non-nicotine e-vaping device; and while the puff detection signal indicates that a puff is not currently occurring with respect to the non-nicotine e-vaping device, detecting, by a second PID controller, a change in an ambient temperature of the HWA, and controlling, by the second PID controller, the temperature setpoint such that the temperature setpoint changes in response to the detected change in the ambient temperature of the HWA.

Abstract: An apparatus configured for database access control. The apparatus includes a memory and a processor coupled to the memory, wherein the processor is configured to execute instructions, The instructions include receiving a statement requesting access for a user to data files stored in a non-transitory memory medium; parsing the statement into one or more arguments, wherein each argument ends with a logical operator; computing a skip count for each of the arguments; evaluating the statement using the skip counts to determine whether the access should be granted to the user; retrieving the data files from the non-transitory memory medium; and sending the data files to the user, if the access is granted.
