Abstract: A session control system for a device includes at least one processor and a memory coupled to the at least one processor. The memory is configured to store instructions. The at least one processor is configured to execute the instructions to cause the session control system to detect when a session has started, start a session timer, increment a puff variable when an airflow sensor detects that a puff has been taken, monitor the session timer against a time threshold and the puff variable against a puff threshold, and in response to a session threshold being met, end the session. The session timer is configured to measure a length of the session and the puff variable corresponds to a total number of puffs taken.

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: Methods and systems for collaborative evidence-based problem investigation and resolution are described. The method includes receiving data related with fault that has occurred in faulty system. The data includes symptoms and details associated with each symptom. The method includes arranging data in symptoms table. The symptoms table includes rows for describing symptoms and columns for defining details associated with each symptom. The method includes facilitating concurrent update of symptoms table by users in order to indicate clues or update details, and causing provisioning of cause-effect UI to facilitate creation of cause-effect graph using clues. The method includes creating cause-tree/fishbone diagram based in part on at least one of: causes defined by users, symptoms and clues defined in symptoms table, components of faulty system, and historical data from prior problem investigations.

Abstract: A low-profile secondary seal for floating-roof storage tanks has a tip seal that is mounted on a series of segmental adapter plates connected to the shoe plates. A fabric extends between the tip seal and the floating roof. A spring presses the tip seal against the tank shell.

Abstract: A low-profile secondary seal for floating-roof storage tanks has a tip seal that includes a series of segmental adapter plates connected to the shoe plates. A tip seal element is mounted on the adapter plates. A fabric extends between the tip seal and the floating roof. A pusher is hinged to the floating roof, and includes a pusher bar with two ends that are disposed in a sliding arrangement against the adapter plates. A spring is connected to the pusher at an inclined angle, providing a mechanical advantage as the spring biases the pusher and pusher bar outwardly against the plates, pressing the tip seal against the tank shell.

Abstract: A method comprising feeding a liquefied refrigerant gas into direct contact with aqueous liquid in an enclosed vessel to chill or cool the liquid and/or produce ice crystals and vaporize the refrigerant by heat exchange with the aqueous liquid; feeding a mixture of cold aqueous liquid and/or ice and refrigerant from the vessel to an enclosed storage tank to provide cold aqueous liquid and/or ice therein; removing refrigerant vapor from the storage tank; converting the refrigerant vapor to liquid refrigerant in a refrigeration cycle and feeding the liquid refrigerant back to the enclosed vessel; and withdrawing aqueous liquid from the storage tank and feeding it to the enclosed vessel; with all said refrigerant and aqueous liquid streams and volumes being in a single closed system such that refrigerant and aqueous liquid are not lost except by inadvertent leaks and consumption of such materials is avoided because they are not withdrawn from the system.
