Abstract: Systems are disclosed for a child car seat harness that is properly tightened automatically.

Abstract: This disclosure is related to systems, devices, and methods of adaptive replication. Adaptive replication can allow a node in a network to optimally determine where, when, and how to retrieve data from other nodes in the network. For example, adaptive replication may include receiving a notification corresponding to data at a first node in the network and selecting a node of multiple nodes in the network to retrieve the data from. The first node may retrieve the data from any node within the network that has the data. In some embodiments, a node may add delays or select where to retrieve data from based on a priority, a bandwidth, or other factors.

Abstract: Systems and methods for autonomously playing audio files at predeterminable times of a day, week, and/or year, including but not limited to astronomical events, for example, dusk or dawn. The systems and methods employ a computer program running on a standalone computer connected to an audio power amplifier and speaker system. The computer program includes an always-running service configured to execute a scheduling algorithm that causes selected audio files to be played according to one or more schedules.

Abstract: A cryogenic fluid cylinder includes an inner vessel for holding cryogenic fluid, a cylindrically shaped outer vessel having a vertical longitudinal axis surrounds the inner vessel and forms an insulating space there between, and operating controls located on a top of the outer vessel. Customer or end user operating controls include a liquid-use valve for selectively dispensing liquid cryogen, a pressure-building valve for selectively controlling a pressure building circuit, and a gas-use valve for selectively dispensing cryogen gas. Supplier or maintenance personnel operating controls include an economizer regulator for selectively setting at least one desired pressure of the inner vessel, a vent valve for selectively venting cryogen fluid, and a vacuum pressure port for indicating vacuum pressure between the vessels. The end user controls are located on a front side of the outer vessel while the supplier controls are located on a rear side of the outer vessel.

Abstract: A system and method for closed loop power supply control in large, multiple processor installations are provided.
