Abstract: A drip emitter is provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. Water enters the emitter through a first inlet and proceeds into a first chamber. When the water pressure is above a predetermined level, a one-directional valve opens to allow fluid flow past the first chamber, through a tortuous path flow channel, and through an emitter outlet. A second inlet is used to compensate for water pressure fluctuations in the supply tube to maintain output flow at a relatively constant rate. Water enters the second inlet and presses a flexible diaphragm toward a water metering surface to provide pressure-dependent control of the output flow. A copper member is mounted to the emitter over the emitter outlet to prevent plant root intrusion into the emitter outlet.

Abstract: There are provided moisture sensing devices. These devices can be used to sense moisture in various mediums. They also can be used to control irrigation through use in valves and electronic switches and data feedback devices.

Abstract: A method and poll control entity (300) for controlling a polling procedure in a radio communication where a data transmitting node (302) transmits data (3:1) to a data receiving node (304) and sends polls to the data receiving node according to a default polling frequency. The polls require the data receiving node to send feedback (3:2) to the data transmitting node indicating whether said data has been received and decoded by the data receiving node or not. The poll control entity detects (3:3a-c) a trigger of the radio communication indicating a deviation of a feedback time which is a time period between a time of sending the poll and a time of receiving the feedback from an expected feedback time range. The poll control entity then adjusts (3:4) the polling frequency based on the detected trigger such that the deviation of the feedback time is reduced, and enforces (3:5) the adjusted polling frequency at the data transmitting node.

Abstract: Apparatus, methods and systems to associate a flight plan of an unmanned aerial vehicle (e.g., a drone) with a cryptographic signature are disclosed herein. Some disclosed examples include one or more non-transitory computer-readable media including computer-executable instructions. The computer readable instructions, when executed by one or more processors, cause the one or more processors to compare a flight path over a geographic area of an unmanned aerial vehicle to a geographically identified no-fly zone. The flight path is included in a flight plan. The instructions also cause the vehicle to determine whether the flight path enters the geographically identified no-fly zone, and based on whether the flight path is determined to enter the geographically identified no-fly zone, associate the flight plan with a cryptographic signature.

Abstract: A method and device for managing establishment of a communications link between an external instrument (EI) and an implantable medical device (IMD) are provided. The method stores, in a memory in at least one of the IMD or the EI, a base scanning schedule that defines a pattern for scanning windows over a scanning state. The method enters the scanning state during which a receiver scans for advertisement notices during the scanning windows. At least a portion of the scanning windows are grouped in a first segment of the scanning state. The method stores, in the memory, a scan reset pattern for restarting the scanning state. Further, the method automatically restarts the scanning state based on the scan reset pattern to form a pseudo-scanning schedule that differs from the base scanning schedule and establishes a communication session between the IMD and the EI.
