Abstract: A swimming pool monitoring system including an imaging sensor for detecting the presence of an object within a defined perimeter of the swimming pool and a computer system operatively coupled to the imaging sensor with a non-transitory computer readable medium storing a program causing the computer system to execute processing to determine when an object is moving within a field of view of the imaging sensor once detected by the imaging sensor, to determine an angle of the object relative to the imaging sensor and to determine a range of the object relative to the imaging device to include a determination of a size of object for providing an alarm when the object approaches within a predetermined distance of the pool edge.

Abstract: A swimming pool monitoring system using a plurality of sensor systems to detect the presence of objects within a defined perimeter of the swimming pool prior to the objects reaching the edge of the pool. The objects may be people or animals. The sensor systems may include a ranging sensor, an audio sensor, an olfactory sensor and a video imaging sensor. The sensors are monitored by a computer system that has stored data for objects authorized to be within the pool perimeter. The system provides an alert or alarm upon detection of an unauthorized or unknown object in the monitored perimeter by comparing detected objects to the stored data. The system can determine the distance of the object from the pool edge and provide an adjustable alarm as the objects nears the pool edge.

Abstract: A multi-panel sign system including first and second panels, and an adhesive-based fastener. The panels include a panel body and complimentary, first and second interlock structures. The panel body defines a front face for maintaining indicia, and first and second sides. The first and second interlock structures are located adjacent the first and second sides, respectively, and project opposite the front face. In an assembled stated, the first interlock structure of the first panel mechanically locks with the second interlock structure of the second panel to establish a interlocked joint, and the adhesive-based fastener is bonded to the first and second panels. The interlocked joint robustly maintains the panels relative to one another, whereas the adhesive-based fastener serves to prevent inadvertent sliding of the panels. Optically active sheeting can be applied to the front face of the panels, and desired indicia applied to the sheeting.

Abstract: A painting accessory support for use with a paint bucket having a handle and a ladder having a rail is disclosed. The painting accessory support includes a hook and a finger loop. The hook is sized to receive the rail of the ladder and includes a first end and a second end. The finger loop is attached to the hook between the first end and the second end. The finger loop is sized to receive a user's finger during movement of the painting accessory support from one location to another.

Abstract: The present application relates to a sign including: (1) a sign blank including multiple first interlockable members; and (2) optically active sheeting including multiple second interlockable members; wherein the first and second matable members interlock with one another to hold the sign blank and the sheeting together.

Abstract: A pavement marking composition, methods of applying, and pavement markings produced therefrom. The composition is a two-part coating composition having an amine component including one or more aspartic ester amines and optionally one or more amine-functional coreactants, an isocyanate component including one or more polyisocyanates, and material selected from the group of fillers, extenders, pigments, and combinations thereof.

Abstract: The invention relates to a method of applying a two-component composition and in particular a two-component pavement marking composition as well as an apparatus suitable for mixing, dispensing and spraying small volumes of a two-component composition.

Abstract: When mounted to a vehicle, a dispenser ejects optical elements so that they have a component of movement that is parallel with the surface of the pavement to which the optical elements are to be applied. Preferably, the component of movement in that direction is more significant than a component of movement directly toward the pavement surface. A fluid assist causes the optical elements to be ejected from the dispenser nozzle at a velocity to at least partially counteract, and preferably match, the forward velocity of movement of the vehicle to which the dispenser is attached. Thus, in accordance with one specific aspect of the present invention, optical elements can be laid down upon marking material that has been applied to a pavement surface at a substantially reduced relative velocity to the road surface.

Abstract: A method of protecting an object during application of a fluid onto a surface. The method includes the following steps, (1) providing a cover having a first layer and a second layer attached together, the first layer including a nonwoven fabric material and the second layer including a plastic material, and (2) positioning the cover relative to the object so that the fluid is prevented from contacting the object during application of the fluid onto the surface. A drop cloth having a first layer which includes a non-woven fabric material, and a second layer which includes a plastic material, is also disclosed.

Abstract: An electronic communications manager for providing an interface between a user using a communication device and a data and/or telephone network is disclosed. The data network, which may include an internet or intranet, is connectible to at least one information provider as well as a second user, and the telephone network is also connectible to the second user. The electronic communications manager can receive and interpret voice, such as from the first user using a telephone, as well as data, such as from the first user using a computer or information appliance. Likewise, the electronic communications manager can provide voice/video, such as for interacting with the first user through the telephone, and can provide data, such as interacting with the first user through the pager or interacting with the second user through the data network. Furthermore, the electronic communications manager can send and receive internet protocol to and from the information provider.

Abstract: A pavement marker has an unpotted upper shell and a lower base plate that together define a housing. A number of ribs are disposed in the housing interior oriented substantially perpendicular to the inner wall of the base plate. The upper shell has inclined end faces, an upper face, and is made of a plastic material having moderate to high flexural modulus and a high impact strength. The lower base plate has a planar inner wall and an opposed planar, pavement-engaging outer wall, and is made of a material having a Young's modulus of at least approximately 300,000 PSI (20.7.times.10.sup.8 Pascal). The ribs are formed unitarily with the inner wall of either the upper shell or the base plate, and extend upwardly from the inner wall of the base plate to the inner wall of the shell. A retroreflective lens is positioned on at least one of the first and second opposed side faces of the marker. The pavement marker resists delamination from a roadway surface when secured to the road with a soft adhesive.
