Abstract: A lighting system and method of driving an array within the lighting system are disclosed. The array includes vertically-stacked multi-color micro light-emitting diode (microLED) devices that emit light of different colors. Driving circuits and a ground switching circuit are controlled by processing circuitry to sequentially emit the colors of each microLED by independently driving pn junctions of the microLED. Each driving circuit includes multiplexers to receive a sink/source current and selectably provide the sink/source current to a channel based on control signals from the processing circuitry. Dimming of a particular color is effected using a pulse width modulated (PWM) signal to adjust a duty cycle over which the sink/source current is applied to the channel. The ground switching circuit selects another channel using multiplexers, and grounds the channel such that current is limited to flowing through one of the pn junctions at a time.

Abstract: A data pipeline validation system and method configured to partially automate testing of data pipelines in a distributed computing environment. The system includes a data pipeline analytic device equipped with various modules, such as a query generation module, data frame comparison module, and metadata management module. The query generation module employs natural language processing techniques to analyze configuration entries and dynamically generate SQL queries tailored to specific test cases. The data frame comparison module compares the results of different test cases using distributed collections, enabling parallel processing and efficient result comparison. The metadata management module captures and stores relevant metadata for traceability and auditing purposes. The system facilitates comprehensive validation of data pipelines, enabling organizations to ensure the accuracy, reliability, and integrity of data.

Abstract: A lighting system and method of driving the array are disclosed. The array includes vertically-stacked polychromic devices having junctions that emit light of different colors. The junctions of each polychromic device along a particular row or column of the array are driven by simultaneously driving multiple separated junctions during one stage of a driving cycle and driving one or more junctions between the separated junctions during another stage of the driving cycle. The polychromic devices are driven by interleaving driving of the rows and columns of the array or by driving all of one of the rows or columns first and then driving all of the other of the rows or columns.

Abstract: Enhanced methods and systems for securing and monitoring cargo are described. Some examples provide a cargo monitoring system (“CMS”) that is configured to track, identify, and report about anomalous conditions or events related to cargo shipments. The CMS may include a software system that receives conditions information from electromechanical locks that secure cargo. The locks include data terminals that facilitate near real time monitoring of cargo. The electromechanical locks are installed on the bars or other mechanism (e.g., door rings) that lock the doors of a cargo container, train car, van door, or the like. The data terminals include logic that is configured to transmit to the CMS information about current conditions, such as location, temperature, lock status (e.g., open, closed), tamper attempts, and the like. The cargo monitoring system interprets the received information and performs various actions based thereon, such as to transmit alerts if anomalous conditions are detected.

Abstract: A fluid pump includes an inlet; an outlet; a motor; and an impeller rotated by the motor about an axis, the impeller being positioned axially between an inlet plate and an outlet plate. The inlet plate includes a channel that receives fluid from the inlet, the channel being defined by an inner wall and an outer wall. The channel has a first region extending over an angle of at least 150° and a second region extending from the first region over an angle of 61.8° to 71.8°. The inner wall has a first radius centered about the axis which is constant over the first region and the second region. The outer wall has a second radius centered about the axis which is constant over the first region and also has a third radius not centered about the axis which is constant over the second region.

The fluid pump also includes a motor having a shaft with an upper end and lower end that rotates about an axis. The fluid pump also includes a motor frame having a top section, a base section, and a plurality of legs that axially separate the top section and the base section. The fluid pump also includes a lower bushing for radially supporting the lower end of the shaft. The top section defines an upper bushing therein for radially supporting the upper end of the shaft and the base section maintains a coaxial relationship between the lower bushing and the upper bushing.
