Abstract: Plastic grid or framework arrangements are used to support and position of bowls that hold flower arrangements, candles, letters, and other decorative elements. These grids are deployable in water fountains, indoor and outdoor pools, and other small bodies of water during festive occasions or for longer term decorative display. The grid themselves do not float, and are positioned below the surface of the water, and thus are not readily visible. Buoyancy is provided at the hubs that form nodes in the grids. The hubs also support floating bowls containing various decorative elements. The resulting effect is that the various decorative elements appear to be floating on the surface while the sub-surface grid structure maintains their relative positioning, keeping the bowls from clumping together at the edges or in the corners of the pool or fountain.

Abstract: One embodiment of this disclosure can provide a system and method for estimating user gazes. During operation, the system can obtain an event stream captured by an event camera monitoring movement of a user's eye, generate an event image by accumulating, at a pixel level, events that occurred within a predetermined interval based on the event stream and determining a pixel value of each pixel based on the accumulated events associated with the pixel, and input the event image to a gaze-estimation machine learning model, which generates a first prediction output regarding a direction of the user's eye movement and a second prediction output regarding a speed of the user's eye movement.

Abstract: A circuit for supplying electrical power at a rated direct current of 20-100 kA to an electrolysis cell is provided. The circuit comprises an upstream and a downstream busbar connected to each other with a short-circuiting device which, when closed by an actuating mechanism, allows the busbars to be electrically connected to each other. An anode bar is equipped with an anode connection interface and a cathode connection interface, for connection to the anode and cathode, respectively. The cathode connection interface is connected to the downstream busbar. The circuit comprises means for absorbing movement of elements of the circuit due to thermal expansion. A disconnector connected to the upstream busbar and to the anode bar is opened by an actuating mechanism and it electrically disconnects the upstream busbar and the anode bar from each other after a non-zero time interval Tm when the short-circuiting device has been closed.

Abstract: System and method embodiments are described that enable generation of an electronic content schedule. In a method embodiment, one or more data files including TV viewing data and descriptive data of a plurality of individuals are received. Target audience criteria, target TV content, and criteria for key performance indicators (KPIs) are received. KPIs for a target segment are tracked. Spot watching probabilities for each individual in the target segment are calculated. A plurality of spot packages is generated based on the target TV content. For each spot package, a probabilistic segment is generated based on the spot watching probabilities and a plurality of KPIs are calculated. Scores corresponding to the spot packages are generated based on the plurality of KPIs and based on tracked KPIs of the target segment. The content schedule is generated by selecting a spot package selected from the plurality of spot packages based on the scores.
