In one aspect, the present disclosure related to a method for modifying a beacon light source for use in a light-based positioning system. In some embodiments, the method includes selecting a modulation scheme for the light source, determining a duty cycle for the light source based on the modulation scheme, the duty cycle having a proportion of time the light source is in an on state and a corresponding proportion of time the light source is in an off state, the proportion of time the light source is in an off state resulting in reduced luminosity of the light source, and supplying additional power to the light source to compensate for the reduced luminosity of the light source by the duty cycle.

Systems and methods presented herein may allow a sending user to stream audio to recipients without providing a permanent audio file, facilitating sharing of audio while retaining control over the audio file and reducing the chances of users copying the file. The sending user may specify number of plays, duration of time audio will be available for streaming, and the number of times the audio can be re-shared in one embodiment. The sending user and recipients may all execute a common client software on their computing devices that causes the computing devices to delete the audio when the streaming is complete and detect attempts to copy the audio at the device.

A building system includes blocks having first and second side surfaces that are perpendicular to a common plane defining a subtended angle, couplers and receivers are defined in the first and second side surfaces such that chains of blocks may be coupled to one another in rows forming closed loops or non-closed chains. Rows may be coupled together by engaging core links with a block in each row and with a core rod passing through each row. Blocks in each row may include a peg and aperture engaging a corresponding aperture and peg in adjacent rows to facilitate alignment. Core rods threadably secure to other cord rods, slanted blocks, caps, and other feature blocks in order to capture a stack of rows in engagement with the core rods. Blocks including decorative features and forming parts of pivoting joints may also be included within a row.

Systems and methods are provided that disclose providing a positioning service for devices based on light received from one or more light sources. This light based positioning service uses light information transmitted by each light source to determine the position of the device. The positioning information can include three dimension position information in a building that can then be used to deliver services and information to a mobile device. The content delivered to a mobile device can include multimedia, text, audio, and/or pictorial information. The positioning information along with other location or positioning information can be used in providing augmented reality or location aware services. The light sources can be independent beacons that broadcast information in visible light at a rate that is undetectable by the human eye. Content can be retrieved from a server over a communications connection.

摘要:
In one aspect, the present disclosure relates to a method for tracking and analyzing information in a location using a light based positioning system. In some embodiments, the method includes determining a position of a device in a location using a light based positioning system, electronically receiving data from the device, and updating a database with said data. In some embodiments, determining the position of the device includes receiving a position determination from the device. In some embodiments, determining the position of the device includes electronically receiving from the device one or more identification codes of one or more light sources that the device has detected using an image sensor on the device and calculating the position of the device using the one or more identification codes.

In one aspect, the present disclosure relates to a self identifying light source including an emitter that produces visible light; and an autonomous modulator in electrical communication with the emitter that automatically and continually modulates the visible light produced by the emitter, wherein the modulated visible light represents an identification code of the light source. In some embodiments, the emitter is a light emitting diode (LED) and further comprising an LED driver that provides a specified voltage and current to each LED in the light source.

A seal, in certain embodiments, includes a seal body having a groove on a face of the seal body. The face is configured to contact a surface of a separate component to form a seal. The groove interrupts continuity of the face between a first face portion and a second face portion. In addition, the groove enables material deformation laterally between the first face portion and the second face portion. Furthermore, the groove increases contact stress at corners between opposite walls of the groove and the respective first and second face portions.
