Abstract: Examples provides sale-restricted items management for self-checkout. A list of sale-restricted items is displayed via a graphical user interface (GUI) provided by a user interface. A notification component transmits a notification to a user device associated with an authorized user to verify a transaction responsive to an unauthorized user selection of a sale-restricted item from the list of sale-restricted items displayed. The notification includes an identification of the selected sale-restricted item and location of the selected sale-restricted item. A verification component authorizes completion of the transaction associated with the selected sale-restricted item by the unauthorized user on condition an age verification is obtained from the user device associated with the authorized user. Responsive to the authorization, an unlocking signal is sent to a locking storage device storing the selected sale-restricted item.

Abstract: An aspect of the invention provides an annular exercise apparatus comprising an annular body having axially spaced annular faces and inner and outer side walls, the body section having a core and a flexible cover layer and defining an aperture inward of the inner side wall and extending axially through the end faces, wherein the aperture defines an annular lip having a diameter greater than a diameter of the aperture and less than a diameter of the inner side wall.

Abstract: Examples provides sale-restricted items management for self-checkout. A list of sale-restricted items is output to a first user via a user interface associated with a self-checkout device. The user interface enables the first user to navigate options associated with selecting a sale-restricted item, including brand, variety, size and quantity options. A notification component outputs a retrieval alert to a set of user devices associated with a second user authorized to retrieve the selected item. The alert includes an identification of the selected item, a location of the selected item, a self-checkout device identifier and an instruction to retrieve the selected item. A verification component verifies an age of the first user. The second user delivers the retrieved item to the first user at the self-checkout for completion of the transaction.

Abstract: An improved pilot valve assembly (14) for hydraulically controlling a pressure reducing valve (12) to maintain and further vary the outlet pressure (P2) of the pressure reducing valve (12) in response to increased flow (f) through the valve (12). The pilot valve assembly (14) comprising first and second movable valve members (100,102). The first and second moveable members (100,102) being acted on by a velocity head pressure sensed by a downstream Pitot tube (90) and a downstream outlet pressure (P2) in a balanced arrangement such that they move in response to both the velocity head and downstream pressure (P2) to open and close the pilot valve (14) and so main valve (12) to both maintain and vary the outlet pressure (P2).

Abstract: The instant invention relates to stilbene optical brightening agents which combine a high solubility in water while providing superior fluorescent whitening effects when applied to the surface of paper in either the size-press or in a pigmented coating composition and which show a reduced anionic charge. The instant optical brighteners may also be used for finishing of textiles.
