Abstract: A distributed transaction ledger (e.g. a blockchain) is used to track and validate changes in a building management system such as a building automation system, access control system, or security/surveillance system. The building management system 100 includes a series of distributed devices connected to a peer-to-peer validation network. The distributed devices generate transaction information during normal operation and broadcast the transaction information to the validation network. The validation network maintains a distributed transaction ledger for the building management system, for example, by validating the transaction information and distributing the transaction information across the validation network according to consensus criteria to be stored locally in multiple instances by nodes of the validation network, which can be dedicated computing devices and/or validator distributed devices.

Abstract: A distributed event engine for controlling distributed devices of a building management system executes as discrete event processes on distributed devices with sufficient computing power and availability. The distributed devices communicate via a peer-to-peer network and a distributed ledger (e.g. blockchain). An event engine configuration module assigns the event processes to the distributed devices based on device and capability information published to the distributed ledger. An edge device scoring process executing on the distributed devices executing the event processes determines which other distributed devices to control based on which devices are compatible with local event processes and/or electrically and geographically close, resulting in decreased latency, vulnerability to hacking and corruption of data.

Abstract: A student tracking system tracks students' location traveling to and from schools and provides information about the students to responsible parties associated with the students such as parents, bus drivers, school administrators, and faculty. Readers read identification information from tags (e.g. radiofrequency identification tags) associated with the students and/or entrance/exit points of school buses, school buildings and/or classrooms and send the identification information along with location information (e.g. via a global navigation satellite system receiver) to a tracking and authorization module, which generates event information for entering and exiting events at the entrance/exit points, verifies that the event information matches predetermined school schedule, bus and route information, detects anomalies in the event information, and generates attendance information.

Abstract: A building automation system generates occupancy information for occupants of spaces of a building (e.g. quantity, identity and/or location of the occupants) based on occupancy sensors in the spaces. The occupancy sensors capture speech sounds originating from one or more occupants of the spaces and/or ultrasonic emissions originating from one or more user devices of the occupants are via microphone arrays. Audio data based on the captured sound is then generated. Position information for the sources of the sound is determined based on the audio data, and the audio data is enhanced based on the position information via a beamforming process. Occupancy information for the spaces is generated based on the audio data. Environmental conditions of the spaces are controlled based on the presence, absence, position, orientation, distribution and/or preferences of the occupants in the space.

Abstract: A system and method for operating a network security system implementing security cameras, motion sensors, access control systems, security door locks, and mobile panic button devices within a monitored area. Security cameras transmit video to a network video recorder and the video is analyzed by a video analytics system to determine if a security event is occurring. If a security event occurs, a security control system calls a dispatch service, which transmits a notification to only those security guards who are within a given area of the event.

Abstract: A service management system facilitates service on building management systems. A connected services system of a connected services system stores temperature information from temperature detectors of building management systems (including heat detectors of fire alarm systems and thermostats of building automation systems), which send sensor values to control panels, which, in turn, send the temperature information to the connected services system. A temperature detector evaluation module of the connected services system retrieves the temperature information from the connected services database, generates aggregate temperature information based on the temperature information and then determines which of the temperature detectors require service based on the aggregate temperature information, for example, by detecting outlier temperature information.

Abstract: A service management system facilitates and validates service on building management systems installed in a building with an access control system. A service workflow module receives device events from control panels of the building management systems and combines them with local service data from mobile computing devices of technicians performing the service, generating service events. A validation module receives the service events and retrieves access control events from an access control system controller of the access control system and determines whether they are coherent. The service workflow module also infers the location of the technician based on the access control events and sends service eligible devices to be displayed on the mobile computing devices of the technicians. In an alternative embodiment, device events from a building automation system such as a heating, ventilation and air-conditioning system are further used to validate the service events.

Abstract: A security system, system user interface, and method for displaying status information from security devices in a networked security system using a multistate alert user interface. The security system supports different features in icons associated with the security devices, displayed on a graphical user interface. This provides operators with the ability to display status information from security devices, such as alert information comprising one or more alerts, by displaying the icons on a topology map of the graphical user interface. In this way, the operator can determine at a glance the number and type of alert information from the topology map without the need to perform additional selection and navigation steps within the graphical user interface.

Abstract: LED lamps having a high color rendering index are disclosed. In some embodiments, such lamps also exhibit high lumen maintenance and low color drift during lamp warm-up. The lamps may include, for example, a light emitting diode (LED) kernel having a mixture of red and blue LEDs, and a converter including a red phosphor in an amount ranging from greater than 0 to about 10 weight % of a total phosphor content of the converter.

Abstract: A light emitting diode (LED) light engine includes a solid transparent dome mounted on one or more LED dies to form a base module, a flexible sheath having embedded therein a phosphor that converts light of a first wavelength range to light of a second wavelength range, the sheath being attached to the base module so that the sheath conforms to a light emitting surface of the dome. The sheath emits light of the second wavelength range when the LED is emitting light of the first wavelength range. Further sheaths may be formed each with different phosphors or phosphor blends, and one of the sheaths may be selected to cover the base module depending on the color of light to be produced by the light engine.

Abstract: A lighting module has a base, a top, a longitudinal axis from the base's center to the top's center, and a lateral edge surrounding the axis. Solid state light sources at the base emit excitation light, having an excitation wavelength and an angular distribution centered about the axis, toward the top. A lens defines a lateral edge of the module, which extends from the base to the top and reflects the excitation light. A phosphor surface of the module, shaped as a funnel having a wide end proximate the top and a narrow end proximate the base, receives and absorbs the excitation light, producing phosphor light that exits the module through the lateral edge. The phosphor light's wavelength is greater than the excitation wavelength, and has an angular distribution at each point on the phosphor surface centered about a local surface normal with respect to the phosphor surface.
