In one aspect, the present disclosure relates to a method for isolating a broadcast digital pulse recognition tone of a beacon light source in a digital video sequence. In some embodiments, the method includes receiving a digital video sequence of a scene, the digital video sequence including a sequence of frames and the scene including both modulated illumination broadcast by a beacon light source and un-modulated illumination, calculating a background value of the digital video sequence, the background value including a portion of the digital video sequence corresponding to the un-modulated illumination of the scene, subtracting the background value of the digital video sequence to obtain an isolated digital video sequence of the modulated illumination of the scene, calculating a frequency content of a frame of the isolated digital video sequence, and determining a particular tone broadcast by the beacon light source based on the frequency content.

In one aspect, the present disclosure relates to a method for demodulating a modulated light signal in a light based positioning system. In some embodiments, the method includes receiving a modulated light signal at a device, the modulated light signal transmitting an arbitrary identifier of a light source, recording the modulated light signal using a rolling shutter image sensor to create a raw image having alternating spaced apart stripes, subtracting background information from the raw image to create an isolated image, taking a Fourier transform of an image representative of the isolated image to calculate a Fourier transformed signal, and determining the arbitrary identifier of the light source based on the Fourier transformed signal.

In one aspect, the present disclosure related to a method for configuring one or more imaging sensors of an imaging device to capture digital images for digital pulse recognition demodulation. In some embodiments, the method includes initializing one or more imaging sensors of the imaging device, determining a subset of the one or more imaging sensors to configure, setting a configuration for each of the one or more imaging sensors of the subset by defining a region of interest as a metering area for each of the one or more imaging sensors of the subset and automatically adjusting a setting for each of the one or more imaging sensors of the subset, and adjusting input parameters of a demodulation function based on a device profile of the imaging device. In some embodiments, the adjusted setting is locked to prevent further adjustment of the adjusted setting.

In one aspect, the present disclosure relates to a method for recognizing a broadcast digital pulse recognition tone in a beacon-based light positioning system. In some embodiments, the method includes capturing a digital image using an imaging sensor of an imaging device, identifying one or more regions of the digital image illuminated by one of one or more beacon light sources, determining a frequency content of each of the one or more regions, and determining a particular tone broadcast by the beacon light source illuminating a particular region using the frequency content of the particular region. In some embodiments, the imaging sensor has a frame rate and includes a rolling shutter, the rolling shutter having a sampling rate greater than the frame rate of the imaging sensor.

A method for measuring the height of a person is provided. A person is positioned in a room having a floor and a ceiling, and the method comprises the steps of: i) providing a measuring device; ii) calibrating the measuring device to determine a first distance from the floor to the ceiling; iii) placing the measuring device on the person's head; iv) measuring a second distance from the person's head to the ceiling; and v) subtracting the second distance from the first distance to calculate the person's height. An apparatus for performing the measurement is also included.
