Publication number: 20190373494Abstract: Methods and system to determine the health of wireless mesh networks are provided. Each radio node of a wireless mesh network transmits Link Quantification Messages (LQMs) interPAN at maximum power to enable adjacent nodes to determine the Received Signal Strength Indication (RSSI) on the wireless link to that radio node. Each radio node also transmits LQMs at successively lower power levels. The adjacent nodes detect a power level at measurable packet error rate to determine a noise floor for the wireless link. An aggregator collects link quantification information from the radio nodes and forms an intercommunication matrix for the wireless network. The RSSI and power level at measurable packet error rate information is used to remove unreliable links from the intercommunication matrix. Nodes are ranked and the reliability and dependability of the nodes is calculated to show the network health.Type: ApplicationFiled: August 15, 2019Publication date: December 5, 2019Applicant: OSRAM SYLVANIA Inc.Inventors: Bruce A.C.

Patent number: 10484828Abstract: Techniques are disclosed for enhancing indoor navigation using light-based communication (LCom). In some cases, an LCom-enabled luminaire configured as described herein may acquire user data from a local computing device and relay it to a server that tracks and analyzes the data to assess statistics for the luminaire's local spatial environment. The disclosed luminaire may receive from a local computing device a request for indoor navigation to a target of interest, such as a remote computing device. The luminaire may relay that request to a downstream luminaire, which delivers the request to the target. The target may respond with data that allows for tracking of its location and indoor navigation thereto, regardless of whether that target is moving or stationary. In a network of such luminaires, data distribution via inter-luminaire communication may be provided, for example, via an optical interface or other wired or wireless communication.Type: GrantFiled: March 24, 2015Date of Patent: November 19, 2019Assignee: OSRAM SYLVANIA Inc.Inventors: Christian Breuer, Bernhard Siessegger, Anant Aggarwal

Patent number: 10462875Abstract: A method for controlling a chromaticity of total light provided by a lighting system includes detecting the total light by a sensor system, determining a component of the total light that is attributable to uncontrolled light, and selecting a calibration for a sensor based on the uncontrolled light, and using the calibration to adjust the output of the sensor system. The calibration tables may be based on spectral responsivity of the sensors in the sensor system and calibration functions rather than physical light sources. Relative intensities of controllable light sources having different xy values are then adjusted to cause the total light provided by the lighting system to approximate a target chromaticity. A daylighting system implementing this method includes controllable light sources with different xy values. The intensities of the controllable light sources are adjusted to augment sunlight to control the chromaticity of total light provided by the daylighting system.Type: GrantFiled: April 30, 2019Date of Patent: October 29, 2019Assignee: OSRAM SYLVANIA Inc.Inventors: Bernhard Siessegger, Richard C.

Publication number: 20190309974Abstract: Disclosed herein are embodiments of an occupancy monitoring system. The occupancy monitoring system includes a thermal sensor configured to monitor a gate (e.g., entry way) to a space. The thermal sensor includes a pixel array that generates a pixel value for each pixel in the pixel array, and the pixel value corresponds to a quantity of heat or thermal information detected by a pixel. The occupancy monitoring system acquires pixel values for the pixels of the pixel array. The occupancy monitoring system determines whether there is a change in occupancy of the space based on changes to a first region (or first pixel cluster) of the pixel array and a second region (or second pixel cluster) of the pixel array over time. The occupancy monitoring system may adjust lighting, temperature, and/or security systems for the space as the occupancy changes.Type: ApplicationFiled: April 10, 2018Publication date: October 10, 2019Applicant: OSRAM SYLVANIA Inc.Inventors: Marijan Kostrun, Anant Aggarwal, Richard C.
