摘要： A system for analyzing a customer's behavior in a store is provided. The system includes a data capturing unit, which has a first sensor configured to capture an image and an activity of the customer at a preset interval in the store during a first time period when the customer navigates a pre-defined area. The system also includes a data processing unit for processing the image and activity of the customer, which creates a behavior file for the customer from the image and the activity captured by the data capturing unit, and creates a statistics for activities of a plurality of customers in the store for a pixel or a predefined zone in the store for a pre-defined second time period wherein the statistics value is set at zero at the beginning of the pre-defined second time period. The system further includes a data reporting unit for presenting the statistics.

摘要： An aspiration sprayer comprises a head which is preferably permanently attached to a container in which additive material is received. The head may or may not be movable between positions controlling the degree of aspiration affected, and is provided with a cap movable between a first position in which the cap seals the container and prevents the additive material from escaping therefrom and a second position in which the container is unsealed and aspiration of the contents thereof can take place. Elements may be provided as part of the sprayer assembly for controlling the flow of the aspirating fluid. The cap is secured in its sealing position by an element which requires special manipulation for release, thereby providing an important safety feature.

摘要： An oscillating sprinkler is specially designed to facilitate assembly, as well as disassembly for purposes of repair of replacement of parts, without sacrifice of water-tight integrity and with improved operating characteristics. The housing for the impulse wheel and for supporting one end of the sprinkler tube is formed of two parts snapped together to effect the necessary seal, the sprinkler tube is mounted therein by a snap action insertion, thereby to define an operating subassembly, and that subassembly is reliably assembled with a mounting subassembly by sliding insertion and snap action retention. The sprinkler tube is sealingly journaled in such a manner as to produce very low friction, thus reducing the load on the impeller wheel and enabling the sprinkler to have a very low pressure drop therethrough, thereby increasing the sprinkling range of the device. The linkage between the impeller wheel and the sprinkler tube is manually accessible and is provided with a snap connection so that the linkage can readily be manually disconnected and connected. The construction lends itself to producing a low-profile, low cost unit.

摘要： A pulsating sprinkler utilizes an improved method of anchoring the helical torsion spring at one end to the sprinkler body and at the other end to the impact arm to facilitate the assembly process and provide a more reliable and uniform spring action. A radially ridged member adapted for connection to a fluid source carries a pair of sector stops, each extending totally about a circumference thereof and having a single tab enabling rotation of the sector stop in both directions. When employed as a full circle sprinkler, the sprinkler automatically corrects the direction of rotation of the sprinkler body in the event that it initially rotates in the wrong direction.

摘要： A pulsating sprinkler incorporating a three-position trip mechanism facilitating forward/reverse rotation and continuous rotation. The trip mechanism includes a trigger for reversing direction of rotation of the sprinkler, a latch for engaging an impact arm, and a control arm for maintaining the trigger in a fixed position. The trigger, latch and control arm are joined to a common pivot on the sprinkler body. A multiple position diffuser and deflector lever is adjustable for various degrees of diffusion or deflection of a water stream. The sprinkler body is easily removed from the bushing assembly by compression of snap fingers located at a terminal end of the spring body. Further, an O-ring radially seals a space between the bushing assembly and the sprinkler body. An impact arm having two plates with separated vanes extending between the plates or an impact arm with a single plate with two downwardly projecting vanes may be used for ease in molding and increasing manufacturing efficiency.
