Abstract: A method for controlling a target switch assembly in a chain of switch assemblies includes distributing the chain of switch assemblies in a wellbore; placing a controller at a head of the wellbore; making a first decision, at the controller, to actuate a corresponding detonator of the target switch assembly; transmitting, from the controller to the target switch assembly, a fire command to activate the corresponding detonator; and making a second decision, locally, at the target switch assembly, to activate the detonator, after the fire command from the controller is received.

Abstract: A downhole system includes a controller located at the surface, a gun string located in a wellbore, the gun string including plural gun assemblies, a thru-line connecting the controller to the gun string, and a detonator block attached to a given gun assembly. The detonator block includes an addressable switch assembly. The gun assembly includes an end plate mechanism that electrically connects to the detonator block. The detonator block has at least one spring-loaded contact connected to the thru-line and the end plate mechanism includes a round electrical contact made as a printed circuit board, and the spring-loaded contact touches the printed circuit board.

Abstract: An automated nutrient injection system is provided. The automated nutrient injection system comprises a nutrient mixing and delivery system coupled to a controller. The nutrient mixing and delivery system is configured to mix a predefined formula comprised of at least one nutrient and water. The controller is configured to receive, store, and execute user-defined settings of the nutrient mixing and delivery system. The controller comprises a remote display, wherein the remote display is viewable on a device physically remote from the nutrient mixing and delivery system.

Abstract: An apparel system including a base layer component and a vest component that safely may be worn by a child in a child safety seat with a five-point harness (including convertible, combination, and forward facing with a harness). This may provide warmth for the child while transitioning from indoors to the vehicle and while traveling in the car. This apparel system also may provide protection from the elements should the child be involved in a vehicle accident. The apparel system may include a vest component, such as with a hood, that may be worn over the base layer, such as a jacket, to provide added warmth for outdoor activities. In embodiments, the vest component may not be intended to be worn, and in embodiments should not be worn, while the child is in the child safety seat. This system may be safe, versatile, and convenient.
