Abstract: An improved light fixture includes a housing that connects to a power source at one end and interfaces with a heat sink, lighting module, and associated lens at the other end. A lens retainer includes an aperture that allows water to flow into a cavity formed within the lens retainer when installed. A portion of the heat sink is exposed to the cavity and can form a surface of the cavity. As a result, the exposed surface of the heat sink can come into direct contact with water that flows through the aperture of the lens retainer. The lens retainer can use multiple apertures in fluid communication with the cavity, providing a path for water to provide a cooling flow to the heat sink.

Abstract: Computerized systems and methods are provided to intelligently and dynamically manage a data center comprising at least one server and at least one central manager. The central manager is programmed to access the at least one server on a predetermined schedule to determine whether at least one application is functioning properly by determining a functionality level. Alternatively, the central manager determines whether the at least one server is actively used by determining an activity level for the server. Based on the central manager's determinations, the system dynamically adjusts the power level of the server, resulting in reduced power consumption and a reduction in wasted resources and unnecessary processing power in the management of servers in a data center.

Abstract: Aircraft with battery thermal regulation systems, including: an aircraft air inlet and an aircraft air outlet; a battery pack including battery cells; and a battery thermal regulation system including a first air channel, a surface of which is in thermal communication with the battery cells so that air flowing through the first air channel exchanges heat with the cells through the surface; and an airflow device for driving an airflow. The battery thermal regulation system has a first and a second mode operation. In the first mode, the first air channel is fluidly connected with the aircraft air inlet and the aircraft air outlet whereby, during flight of the aircraft, air can enter the aircraft through the air inlet, flow through the first air channel and exit the aircraft through the air outlet. In the second mode, the airflow device drives an airflow through the first air channel.

Abstract: Examples described herein include systems and methods for improved acid-dispensing for pools. An example method can include drawing electrical current at the device through a low-power data channel to charge a battery. The example method can also include receiving at the device, through the data channel, a digital signal instructing the device to dispense acid. The digital signal can include an indication of an amount of acid to be dispensed by the acid-dispensing device. The acid-dispensing device can authenticate the digital signal and discharge acid based on the signal. For example, discharging acid can be performed by powering a pump using energy stored in the battery of the device. In some examples, the acid-dispensing device can confirm water flow to the pool before discharging acid.

Abstract: Examples described herein include systems and methods for improved water level management in a body of water, such as a pool, spa, or pond. An example system includes a water sensor in a static pipe connected to a body of water, a processor receiving signals from the sensor, a memory, and a battery charged via a low-power data channel. When the sensor detects a low-water-level condition, the system opens a fill valve to add water to the body of water. An ultraviolet light can illuminate a portion of the pipe for purposes of preventing algae growth, and an orientation sensor provides a level of safety by deactivating the light for orientations outside a threshold range that could indicate installation or maintenance on the system. The system components can all be contained in a housing that can be mounted to an end of the static pipe.

Abstract: Techniques to facilitate verification of in-situ network telemetry data of data packet of data traffic of packet-switched networks are described herein. A technique described herein includes a network node obtaining a data packet of data traffic of a packet-switched network. The data packet includes an in-situ network telemetry block. The network node obtains telemetry data and cryptographic key. The cryptographic key confidentially identifies the network node. The node encrypts at least a portion of the telemetry data based on the cryptographic key to produce signed telemetry data and updates telemetry-data entry of the in-situ network telemetry block. The telemetry data and signed telemetry data is inserted into the telemetry-data entry. The node forwards the data packet with the updated telemetry-data entry to another network node of the packet-switched network.

Abstract: Systems and methods for dynamically controlling chlorinator operations based on chlorine demand may include receiving an operation command associated with a chlorinator for a fluid system with a chlorinator operation management controller (“management controller”). The management controller may determine a remaining runtime for the chlorinator and access measured values for fluid conditions from a plurality of fluid condition sensors for fluid of the fluid system. The management controller may determine a current chlorine demand based on the measured fluid conditions and a predetermined threshold for a chlorine level for the fluid. An operation of the chlorinator between an active state and an inactive state may be caused by the controller based on the current chlorine demand, the remaining runtime, and a configuration of components for the fluid system. Causing the operation of the chlorinator may include managing operations of a legacy control for the chlorinator.

Abstract: A sensor assembly may include a chassis, cover, first sensor, second sensor, and a control system. The chassis may include a first housing that defines a chamber with the cover and includes a partition within the chamber. A second housing of the chassis may define first and second ports in fluid communication with the chamber. A central wall may extend from an inner surface of the second housing and a protruding wall may extend over the central wall. Both the partition and the central wall may extend from locations along a longitudinal axis of the sensor assembly that are between the first port and the second port. In some examples the protruding wall and the partition direct a portion of fluid flowing within the second housing into and out of the chamber, and the first and second sensors detect values for respective fluid parameters for the portion of fluid.

Abstract: A salt water chlorinator assembly along a closed loop water circuit incorporates a chlorinator cell subassembly and a flow switch subassembly into respective fluidly connected chlorinator assembly housing interior portions. The chlorinator cell subassembly includes an electrolysis cell controlled by a chlorinator printed circuit board. The flow switch subassembly includes a flow sensor mounted upon a printed circuit board assembly (PCBA). A flow switch cable selectively attaches to a PCBA connector. Water flow rate data generated by the flow switch sensor, communicated via an external controller to a smart circulation pump, is used to enable automatic adjustment of the pump speed based upon the flow rate data. The external controller may further alert an end user of undesirable flow rate deviations due to a condition (e.g. a clogged pump/skimmer basket and/or dirty filter) along the closed loop circuit requiring attention.

Abstract: In one embodiment, a method includes activating a first network apparatus within a network and determining, by the first network apparatus, that a Scalable Group Tag (SGT) Exchange Protocol (SXP) is configured on the first network apparatus. The method also includes costing out the first network apparatus in response to determining that the SXP is configured on the first network apparatus. Costing out the first network apparatus prevents Internet Protocol (IP) traffic from flowing through the first network apparatus. The method further includes receiving, by the first network apparatus, IP-to-SGT bindings from an SXP speaker, receiving an end-of-exchange message from the SXP speaker, and costing in the first network apparatus in response to receiving the end-of-exchange message. Costing in the first network apparatus allows the IP traffic to flow through the first network apparatus.
