Abstract: Techniques and architecture are disclosed for mobile transport systems configured to determine vehicle positions within an area using light-based communication signals. The system includes a plurality of luminaires located in an area and configured to transmit luminaire position data recognizable by a sensor disposed on a vehicle. The sensor receives an image of a luminaire including a light-based communication signal encoded with luminaire position data. Luminaire position data can be combined with luminaire layout information to determine a known location of the luminaire. A vehicle position relative to the known luminaire location can be determined based on mathematical relationships. Vehicle orientation relative to the area can be determined based an asymmetric fiducial pattern or multiple known luminaire locations. The system can combine a vehicle position relative to a known luminaire location with vehicle orientation relative to the area to determine a vehicle position relative to the area.

Abstract: Techniques for determining an actual position of a portable device are disclosed. In an embodiment, a two-tier triangulation and wireless beacon-enabled luminaire detection approach is implemented. An estimated position of a device is determined using wireless (e.g., wireless beacon) triangulation based on a signal parameter of a signal received from a wireless access point. The field of view of the portable device may be used to estimate positions of luminaires proximate the portable device. The actual position of the luminaires may be determined from the estimated position by querying a database. A second triangulation may be performed using the known position of the luminaires to determine the position of the portable device with respect to the actual position of the luminaire.

Abstract: Techniques are disclosed for identifying and controlling light-based communication (LCom)-enabled luminaires. In some cases, the techniques include a luminaire communicating its ID to a computing device via one or more LCom signals. In some cases, a user may be able to aim a rear-facing camera of a smartphone at the luminaire desired to be controlled. Once the luminaire is in the field of view of the camera, the ID of the luminaire can be determined using one or more LCom signals received from the luminaire. The ID of the luminaire may be, for example, its internet protocol (IP) address or media access control (MAC) address or another unique identifier. Once a luminaire has been identified, commands can be issued to the luminaire to adjust one or more characteristics of the light output, such as changing the dimming percentage of the light output.

Abstract: Techniques are disclosed for augmenting global positioning system (GPS)-based navigation via light-based communication (LCom). In accordance with some embodiments, a light-sensing device, such as a camera or an ambient light sensor configured as described herein, may be used to detect an LCom signal transmitted by a local LCom-enabled solid-state luminaire. The LCom signal may include data about the location of the transmitting luminaire, and in some cases that location data may be used, for example, in computing the amount of time that it would take to navigate indoors to the luminaire's location. In some instances, GPS data also may be considered to calculate the total trip duration for an entire trip, including time spent indoors and outdoors. In some other cases, the location data and, if available, GPS data may be used, for example, in computing an automotive navigation route.

Abstract: Systems and methods for detection of interconnected outputs of a power supply are provided. A first channel of a power supply is activated, such that power is supplied to a first load connected to the first channel. A first load voltage is measured for the first load. A second load voltage is measured for a second load connected to a second channel of the power supply. The second load voltage is compared to the first load voltage to generate an interconnection result. The power supply is shut down when the interconnection result indicates that the second load voltage matches the first load voltage, such that all channels of the power supply do not supply power to any load connected thereto.
Abstract translation: 提供了用于检测电源的互连输出的系统和方法。 激活电源的第一通道，使得电力被提供给连接到第一通道的第一负载。 测量第一个负载的第一个负载电压。 测量连接到电源的第二通道的第二负载的第二负载电压。 将第二负载电压与第一负载电压进行比较以产生互连结果。 当互连结果指示第二负载电压与第一负载电压相匹配时，电源关闭，使得电源的所有通道不向与其连接的任何负载供电。

Abstract: Techniques are disclosed for programming a luminaire with location information, referred to herein as commissioning. Location information may include relative location information (e.g., the position of the luminaire relative to a reference point) and/or absolute location information (e.g., global coordinates for the luminaire). A commissioned luminaire can be configured to emit its location information via light-based communication (LCom). In some cases, the luminaire can be commissioned manually, by hard coding the luminaire with its location either at the luminaire itself or using a device (e.g., a smartphone, tablet, or a dedicated luminaire commissioning device) to program the luminaire with location information. In some cases, the luminaire can be commissioned automatically. In some cases, the luminaire may be configured to provide visual, aural, or tactile feedback to indicate that the luminaire has not received location data or that the luminaire has been moved.

Abstract: Techniques are disclosed for enhancing indoor navigation using light-based communication (LCom). In some embodiments, an LCom-enabled luminaire configured as described herein may include access to a sensor configured to detect a given hazardous condition. In response to detection of a hazard, the LCom-enabled luminaire may adjust its light output, transmit an LCom signal, or both, in accordance with some embodiments. A given LCom signal may include data that may be utilized by a recipient computing device, for example, in providing emergency evacuation routing or other indoor navigation with hazard avoidance, emergency assistance, or both. In a network of such luminaires, data distribution via inter-luminaire communication may be provided, in accordance with some embodiments, via an optical interface or other wired or wireless communication means. In some cases, the network may include a luminaire that is not LCom-enabled yet still configured for inter-luminaire communication.
