摘要： There is disclosed a power drop assembly which includes a housing and a reel positioned and rotatable within it. Preferably, the device determines, not only whether power is available, but how much power is available. Preferably, the power drop assembly also contains a processor and non-transitory storage medium, so that user settings and profiles as well as settings and profiles for the power drop assembly can be stored and run. Additionally, the power drop assembly preferably contains a wireless transceiver which connects to a home Wi-Fi network and then to a cloud account, user profiles and settings, and settings and profiles for the power drop assembly can be saved on the cloud account. In this way multiple users can use the power drop assembly without contradicting instructions or resetting the power drop assembly every time it is used.

摘要： What is claimed is a downhole lubrication system comprising a drill string component comprising an outer diameter and an inner bore. A reservoir may be disposed intermediate the outer diameter and inner bore. A piston may be disposed at least partially within the reservoir. At least one channel may extend from the reservoir to a bearing surface. As drilling fluid is passed through the inner bore, the piston may be pressurized, urging lubricant toward the bearing surface via the at least one channel.

摘要： An overhead battery charger is disclosed. The overhead battery charger includes a source of electric power, for example an electrical outlet, as well as a power cord connected to the source of electric power. At least one battery connection device, such as alligator clamps, is attached to the power cord, and a controller adapted to adjust voltage, current, or both, is available at the battery connection device. In addition, a remote device, such as a smart phone, tablet, or computer, runs an app and sends signals to direct the adjustments made by the controller.

摘要： A housing for a digital assistant is disclosed. The housing includes; a body holding the digital assistant; attachments for an overhead mounting system. Within the housing there is at least one electrical input; and at least one electrical output; along with a digital current limiter. The digital assistant is capable of receiving and implementing instructions via voice commands or a personal control device. The digital current limiter receives instructions from the digital assistant and in response to those instructions, regulates the current to components in communication with the digital assistant. A method for using the housing and digital assistant to create a smart garage system by regulating access to connected components is also disclosed.
