Abstract: Systems and methods for delivering data-driven experiences of a product are described herein. In some embodiments, a server receives user data associated with a plurality of users using the product. The server identifies, from the plurality of users, a first user belonging to a first cohort based on at least one of user behaviors and user properties associated with the first user included in the user data. The server causes an experience of the product to be delivered to the first user. The server then detects that the first user has switched from a first device to a second device. The server further causes the experience to continue to be delivered to the first user.

Abstract: A motor drive is constructed to include a DC motor, the DC motor having a worm at the output shaft thereof, a speed reducing mechanism formed of a main shaft and worm gear meshed with the worm and axially slidably mounted on the main shaft, a clutch adapted to control engagement between the main shaft and the worm gear, a mechanical step counter adapted to control forward/backward rotation of said DC motor, and an electronic step counter adapted to detect the pulse of the DC motor and to calculate the time to control forward/backward rotation of the DC motor.

Abstract: An improved electrical rolling door transmission including one door controller with one pair of transmission gears, two cams, one position cover and two adjustable shafts, all contained in the FixDisc, allowing the user to adjust manually and directly in the limited maintenance space, keeping the limiting position steady after adjustment, thus facilitates the maintenance. One positioning board is installed between the wheel and the driving motor for the user to dismantle the driving motor directly while eases maintenance and assemblage. Furthermore, several sockets on one side of the clutch disc of the FixDisc allow the inserting shaft to insert into any of these sockets for reposition, instead of waiting for reposition by revolving for a big circle, providing better reposition mechanism. While no replacement for a new clutch is needed in case of any socket being damaged, the maintenance cost generates more economic benefits.
