A server apparatus includes a communication interface and a controller configured to transmit and receive information via the communication interface, wherein the controller is configured to transmit an instruction for controlling light emission by a plurality of floor coverings, each floor covering including a light emitting element, to the plurality of floor coverings based on positional information for a first point where a pedestrian is located in an area where the plurality of floor coverings are disposed and positional information for a second point different from the first point in the area.

The subject matter described herein includes a roadway stud control system including a local stud control system positioned along a first section of a roadway, a plurality of roadway studs, each roadway stud disposed on a surface of the first section of the roadway and communicably coupled to the local stud control system, wherein the local stud control system is configured to communicate a control signal to control at least one aspect of the plurality of roadway studs.

A pacing system signals runners with lights indicating if the runner is ahead or behind a preset pace as the runner proceeds around a running track. The system includes a controller that provides pace setting, start, stop, pause, and reset functions; pacing stations (e.g., 20) that are placed at intervals around the running track; and a cart for transport and battery charging. Paces are setup in the controller with a specific number of laps and a time per lap. Bright LED lights in LED matrices in the pacing stations signal the runners outdoors in sunlight. The controller wirelessly communicates with the pacing stations to signal the pacing stations to light at intervals determined by the preset pace. The system may support two or more simultaneous paces and variable pacing per lap to accommodate multiple runners.

A water display including a number of pixels or manifolds that may include water nozzles to emit streams of water and/or other utilities such as lighting is described. The water streams may be pixelated so as to provide a high resolution waveform or other choreography. The choreography transitions between waveforms to provide the appearance of a cascading or undulating wave. A tool to design the water display and simulate its appearance is also described.

Disclosed is an outdoor light fixture assembly having a housing and a lens module. The lens module is removable from the housing for servicing. The removable lens module includes a socket for one or more light sources and a lens. The outdoor light fixture further includes engagement structures for installing and removing the lens module from the housing without the use of tools.

A server apparatus includes a communication interface and a controller configured to transmit and receive information via the communication interface, wherein the controller is configured to transmit an instruction for controlling light emission by a plurality of floor coverings, each floor covering including a light emitting element, to the plurality of floor coverings based on positional information for a first point where a pedestrian is located in an area where the plurality of floor coverings are disposed and positional information for a second point different from the first point in the area.

An integrated cap for retrofitting an existing light fixture can include an integrated cap housing that is configured to be disposed atop a pole that supports the existing light fixture, where the integrated cap housing includes a communication module and a transceiver. The integrated cap can also include a first coupling feature disposed at a bottom end of the integrated cap housing, where the first coupling feature is configured to couple to a first component of the existing light fixture to provide electrical signals to the communication module and the transceiver, where the communication module and the transceiver communicate with a second component external to the existing light fixture.

A safety device comprises a light source, a power source coupled to the light source, a controller coupled to the light source and the power source to control operation of the lighting device, and a connection port that transmits and receives power up and control signals. In some embodiments, the connection port transmits and receives a wired signal. In further embodiments, the connection port transmits and receives a wireless signal. In some embodiments, the connection port receives a signal from an external source. In some of these embodiments, the external source is a remote control. In further embodiments, the external source is a program located on a computing device. In still further embodiments, the external source is one or more additional connection port of one or more additional safety devices. In some embodiments, the signal is a signal to power the light source.

An airfield light, components thereof, and associated methods. The airfield light can include a baffle including a baffle body and one or more baffle members secured to the baffle body. The baffle members are configured to cover portions of a baffle window. At least one light source is mounted in association with the baffle and emits light out of the baffle window. The baffle members cover portions of the baffle window for blocking light transmission therethrough. A method of assembling an airfield light includes arranging a baffle to shroud a light assembly and removing a baffle member to permit light from the light assembly to emit through a portion of a baffle window opened by removing the baffle member. A baffle for an airfield light is also disclosed.

The device is comprised of two panels in the shape of “L”s that are interwoven with each other when they are placed on the sides of a fence. The device is secured to the ground through a series of holes for that purpose. Additionally, an expander has been placed on the section of the device, both vertical and horizontal, to address the issue of uneven terrain. A row of embedded lights is installed in each of the horizontal panels to provide additional illumination. Alternatively, a series of embedded wires may be installed in the horizontal panels that rest on the ground to provide a small (but not deadly) shock to prevent animals from entering the yard or preventing a family pet from leaving the yard.
