An emergency wayfinding device includes a lighting circuit constructed and arranged to change at least one property of a light emitted from a light emitting element, and an electrical conduit including a plug. The plug of the electrical conduit is constructed configured to be received in a socket and to draw electricity from the socket to power the lighting circuit via the electrical conduit.

Emergency wayfinding technology

A light dimming system includes one or more lights and includes a local light controller that includes a dimming controller and a processing circuit, the dimming controller configured to provide an output to the one or more light drivers. One or more electronic processors are configured to receive a dimming input value indicating a desired dimming level for the one or more lights. The processors are further configured to determine a configuration of the one or more light drivers, wherein the configuration defines whether the one or more light drivers utilize a non-linear dimming curve or a linear dimming curve, and provides the dimming controller a dimming level to output a dimming control signal to the one or more light drivers equivalent to the received dimming input value based on a non-linear or linear calculation.

Systems and methods for a perceived linear dimming of lights

An emergency wayfinding device including a lighting controller, a lighting circuit, and a light emitting element. The emergency wayfinding device may draw electricity through a twist-lock plug or draw it from a power source such a battery or a photovoltaic cell. The wide-area communications device is in electrical communication with a connected lighting controller and is configured to send and receive signals or messages to and from a central broadcasting device as well as other emergency wayfinding devices. The lighting controller is configured to change a property of light emitted from a light emitting element based upon signals or messages received by a wide-area communications device. The wide-area communications device communicates a received message or signal to the lighting controller and the lighting controller generates a lighting control signal or message. The lighting controller communicates the generated lighting control signal or message to the lighting circuit, and in response, the lighting circuit changes a property of the light emitted from the light emitting element based upon the lighting control signal or message.

A method of two-way communications over a power distribution network in which outbound communication signals (O) and an inbound communication signals (I) modulate a time-varying waveform propagated through the network, on the low voltage side of the network. An outbound signal waveform is detected at a customer location (C) with remote communication equipment (RCE) at the customer location then producing a return or inbound communication signal. A corresponding inbound signal is produced in an associated voltage waveform and this signal is detected and processed by a distribution concentrator unit (DCU) at the sending end of the network. The transmission and detection of signals on the low voltage side of the network requires less energy than the generation, propagation, detection, and processing of signals on the high voltage side thereof.

Detection of inbound signals in the voltage domain of an electrical distribution network

A device for detecting localized retinal damage derives focal responses of the retina from the global response of the retina to patterned stimuli in one's visual field. The stimuli comprises a series of patterns which spatially vary according to a function of a family of orthogonal functions. Each pattern also varies temporally either by being flashed before the patient or by being reversed in contrast at a fixed frequency. An electroretinogram (ERG) or magnetoretinogram (MRG) response of the patient's eye to the series of patterns is fed back into a computer generating the patterns. The responses are used by the computer to determine the coefficients of the transform of the function of the retinal response. The computer calculates the inverse transform associated with the orthogonal functions and provides the retinal response as a function of position on the retina. Contrast, intensity and temporal frequency of the patterns are chosen for a linear response of the eye. Color, intensity and temporal frequency may also be chosen to test different retinal functions. A lock-in amplifier provides the computer the signal amplitude and phase lag of the responses. A signal averager provides the computer an improved signal to noise ratio of the responses.
