    摘要: A method for measuring the infiltration of coring fluid into a core sample taken from a formation comprises a) providing a coring fluid containing cesium in a first concentration, b) using the coring fluid and a coring means to generate the core sample, c) determining the concentration of cesium present in the core sample; and d) comparing the core sample cesium concentration to the first concentration. A further preferred step comprises using the comparison in step d) to calculate the degree of infiltration of the coring fluid into the core sample.

    摘要: There is disclosed a system for sharing power among interconnected tools which is made up of multiple battery-powered tools, each with a battery. Each tool and its battery are electrically connected to a hub, and the hub is adapted to provide charging current to each battery, to monitor the charge level of each battery and to direct current from one battery with a higher charge level to a battery with a lower charge level. The system is also adapted to enable the hub to direct power to corded electric tools.

    摘要: A power drop assembly is disclosed which, in general, includes a power cord housing, a reel, a power cord, a female power outlet, an electrical input, switching circuitry, and a controller. The reel is positioned within the power cord housing. The reel is rotatably connected to the power cord housing. The power cord is mechanically attached to the reel. The female power outlet is mechanically and electrically attached to the power cord. The switching circuitry is electrically connected to the electrical input. The switching circuitry selectively, electrically connects the electrical input and the power cord. The switching circuitry is electrically connected to the power cord. The controller is communicatively connected to the switching circuitry for controlling the switching circuitry. The controller is also connected to circuitry programmed for regulating the amount of power available to the power cord. The switching circuitry and the regulating circuitry determine whether power is available and how much power is available. The switching circuitry may also be configured to act as a circuit breaker.

    摘要: A fan assembly is disclosed. The fan assembly is comprised of a fan with a motor and a blade as to create an airflow, and an actuator which is adapted to move the fan in vertical and horizontal directions, such that the fan directs airflow below it. The fan further comprises a controller adapted to control the adapter, and a remote control which is adapted to control the controller. The remote control sends signals to direct the controller, and both are adapted such that the movement of the fan can be programmed to a path set by a user and can also be manipulated to a static position set by the user. Preferably, the remote control is a smart device, such as a smart phone.
