Abstract: A method for using location-based services for service management is discussed. The method includes receiving, at a server, a user request from a user device at a geographical location. The method includes accessing a store search to determine a store reference based on the user request and a user location corresponding to the geographical location, the store reference indicating tenant(s) accessible to the user via a user interface (UI) of the user device. The method includes accessing location data for the user device based on the store reference and a user account associated with the user, the location data indicating a service accessible via the UI and associated with a certain tenant. The method includes providing, to the user device and based on the location data, a user experience for accessing the service via the UI.

Abstract: In a slide projector a plurality of slide films contained in a tray are successively selected and shifted to a projected position. A switch is provided which controls movement through a clutch to a running motor of each slide film between its tray-stored position and its projection position and also movement of the tray itself. This switch serves also as a switch for resetting a timer which holds each slide film in its projected position for any desired time.

Abstract: The device is provided with a lever which is pivotally mounted at one end and is urged in the downward direction by a spring, a slide-carrying shoe being attached at the free end of the lever. The lever has an upwardly curving centre portion which rests on a roller mounted on a disc driven at half-speed by a motor. The device also comprises a slide guide consisting of two prismatic rails, one of which is stationary, while the other is secured to a carriage mounted displaceably in the plane of the slide and capable of being pulled towards the stationary rail by means of a spring. There is a coupling pin on the carriage which is engaged with a control cam provided on the lever-driving disc, the said cam being designed in a manner such that the movable prismatic rail is pulled back only during the downward movement of the slide shoe which moves between the prismatic rails, the said slide being otherwise pressed against the stationary rail under the action of the spring.
