Abstract: A vaporizer device includes various modular components. The vaporizer device includes a first subassembly. The first subassembly includes a cartridge connector that secures a vaporizer cartridge to the vaporizer device and includes at least two receptacle contacts that electrically communicate with the vaporizer cartridge. The vaporizer device includes a second subassembly. The second subassembly includes a skeleton defining a rigid tray that retains at least a power source. The vaporizer device also includes a third subassembly. The third subassembly includes a plurality of charging contacts that supply power to the power source, and an end cap that encloses an end of the vaporizer device.

Abstract: Data account management systems and methods are described. A server is in communication with one or more information source systems, at least one user device associated with at least one user and one or more electronic data accounts associated with the user. The server links the electronic data accounts, monitors data among the information source systems and the linked accounts for any changes in activity associated with the user, predicts a behavioral activity of the user via machine learning based on at least one of the monitored data and historical data associated with the user, identifies at least one notification instruction specific to the user based on the predicted behavioral activity, and generates an interactive graphical user interface (GUI) for display on the user device. The interactive GUI presents one or more of the notification instruction and a user profile of the at least one user among the linked accounts.

Abstract: A system includes a current source circuit; a system power input; and load switching circuitry coupling the current source circuit and the system power input to an output configured to couple to a vaporizer heating element. The current source circuit, the system power input, and the load switching circuitry form part of an integrated circuit. Related apparatus, systems, techniques, and articles are also described.

Abstract: ?2-6-Sialyltransferase (2,6ST) variants having improved ?2-6-specific sialidase activity as compared to the native 2,6ST enzymes are described. The variants include GT80 sialyltransferases such as P. damselae Pd2,6ST. Methods for making de-sialylated products and screening sialidase activity are also described.

Abstract: A thermal recirculation valve (TRV) is described that provides for effective fuel module heating during cold operation to mitigate fuel waxing or gelling issues. The TRV allows for the control of heated return fuel flow into the module dependent upon the module's outlet fuel temperature without the return fuel directly contacting the wax element. The wax element is isolated from direct contact with the higher temperature return fuel through use of an elastomeric seal which prevents return fuel from directly contacting the wax element. In addition, the wax element is positioned in the fuel outlet of the module.

Abstract: A method of communicating datagrams between terminals (nodes) of a communications system. In systems operating over unreliable media, redundancy check data can be included in a datagram for use in verifying the integrity of the datagram when received by a terminal; and satisfactory receipt of the datagram can be confirmed by the receiving terminal issuing a response datagram to the originating terminal, for example an acknowledgement. The redundancy check data of a received original datagram (which redundancy check data includes information on the identity of the originating terminal and the content of the datagram) is utilized in the generation of new redundancy check data for the acknowledgement (or other type of response) datagram. The originating terminal receives and processes the response datagram in conjunction with its own local record of the redundancy check data of the original datagram.

Abstract: A laptop computer system executes automatic battery calibration to improve the accuracy of the battery's internal charge monitor. The calibration procedure drains the battery to approximately 0% of charge capacity during normal computer operation, permitting a user to operate the computer without risking power failure when the battery discharges. The computer returns to normal operation if either the AC power or the battery is removed. During the calibration procedure, the computer system prevents power management software from forcing shut down before the battery completely drains.
