Abstract: Aspects are provided for controlling outdoor lighting systems using a photocontrol interface that can be connected to a motion sensor and a luminaire driver or ballast. In some aspects, a dimming control node is electrically and communicatively coupled to a motion sensor via wired connections to a photocontrol interface. The dimming control node is also communicatively coupled to a luminaire ballast or driver. The dimming control node can provide power to the motion sensor. The dimming control node can also receive sensor data from the motion sensor via one of the wired connections. The dimming control node can determine a sensor output state of the motion sensor from the received sensor data, and can select a dim-level configuration corresponding to the determined sensor output state. The dimming control node can cause the luminaire ballast or driver to implement the selected dim-level configuration.

Abstract: In traction cleat and receptacle system in a shoe outsole, unauthorized cleats are prevented from connection to a receptacle by a projection in the receptacle cavity and a recess in the cleat attachment stem for receiving the projection. A locking arrangement includes an annular array of twelve locking teeth on a boss surrounding the receptacle cavity, wherein every fourth tooth has a steeper side angle to in cooperate with mating cleat locking posts. A cylindrical shroud prevents the locking posts from damaging the outsole material during cleat rotation.

Abstract: Lighting control devices, network systems, and methodologies, including methods for providing closed-loop dimming control of such systems, are described. In some examples, disclosed methods and device configurations may include an intelligent photo control configured to accept target dimmed fixture wattage value commands from a user, and provide closed-loop control at the fixture to achieve that target wattage via real-time adjustment of the 0-10V dimming control signal sent to the LED driver. As such, the need for trial-and-error adjustments of the 0-10V analog control voltage, or derivation of dim voltage to fixture wattage response curves in order to achieve a desired fixture wattage level, may be reduced or eliminated.

Abstract: Adjustable traction is provided in a traction cleat by selectively restricting or not the amount of flexure permitted for a dynamic traction element on the cleat. Restricting flexure is alternatively achieved by an adjustably positionable ring or by rotating the cleat to align the dynamic element with different shoe sole topographical features. A dual locking post is provided to reduce the surface area required on the cleat hub for locking structures. The cleat is formed in a two shot molding process that permits elongations of the dynamic traction elements without sacrificing the integrity of the cleat structure.

Abstract: Lighting fixture control systems and method are described including a control station configured to communicate with a plurality of remotely located fixture control devices that are associated with lighting fixtures. Individual fixture control devices may be configured to perform automatic activation operations, that include the fixture control device determining one or more of an identifier of the node, a GPS coordinate of the node, an operating Voltage of the node, a lamp Wattage of the lighting device, a lamp type of the lighting fixture, and a dimming capability of the lighting fixture. The fixture control device may be configured to send results of the automatic activation operation to the control station. The control station may be configured to store a file associated with the node, including the received results of the automatic activation operation.

Abstract: A traction cleat applicable for use in field sports is provided with dynamic traction elements having larger radial thickness, cross-sectional area and mass than dynamic elements in golf shoe cleats. The strength of a locking arrangement for the cleat in a shoe-mounted receptacle is enhanced by providing an annular array of spaced locking stubs on the receptacle to engage a similar array of spaced locking posts on the cleat.

Abstract: Aspects provide photo-control receptacles having contact terminals via which control signals can be communicated. In one aspect, a photo-control receptacle is provided. The photo-control receptacle includes an interface having a neutral conductor and a line voltage conductor. Each of the neutral conductor and the line voltage conductor can form a first electrical connection for providing power to a photo-control via alternating current. The photo-control receptacle also includes one or more additional contact conductors adjacent to the interface. The one or more additional contact conductors can form a second electrical connection for providing control signals to the photo-control.

Abstract: A method of controlling a dynamic physical system comprising a plurality of variable quantities. A model of the system comprising a plurality of variables representing the variable quantities, and a plurality of respective rate equations that describe the rate of change of the variables, is obtained. A control term in at least one rate equation from the plurality of rate equations is identified. A rate control function is derived from, for at least one of the variables in the rate equation, the proportion of the variable to the growth rate of the rate equation, and the rate control function is applied to the control term to provide a stabilised control term. The dynamic physical system is then controlled by modifying at least one of the quantities represented by the variables in the control term, so that the control term derived from the modified quantities is substantially the same as the stabilised control term.

Abstract: A thinner shoe mounted receptacle results from a thin cleat attachment flange received in a shallow receptacle cavity. An angled interface between the cleat and receptacle provide a friction fit engagement to minimize inadvertent disengagement of the cleat and receptacle. Rotational locking occurring inside or outside the cavity further prevents inadvertent cleat rotation. Multiple positionally synchronized angular stops positively define the final angular orientation of the cleat in the receptacle.
