Abstract: This disclosure describes, in part, a mobile apparatus for identifying items. For instance, the mobile apparatus may include a frame, a basket that attaches to the frame, a tray that attaches to the frame, and a user-facing module that attaches to the frame. Weight sensors may be located beneath the basket and the tray in order to determine the weights of items added to the mobile apparatus. The user-facing module may include imaging devices, such as cameras, that the mobile apparatus uses to perform one or more functions. For example, the mobile apparatus may use the imaging devices to identify items placed within the basket, determine locations of the mobile apparatus within a facility, and/or the like. By including these components, the mobile apparatus is able to generate data that represents the items added to the mobile apparatus, the weights of the items, and the costs of the items.

Abstract: Examples described herein include systems and methods associated with a mechanical service tool. In one example, the service tool includes a power jar, an accelerator, and a linear actuator. The accelerator can be coupled to the power jar and provide assistance to the power jar. The linear actuator can be coupled to the accelerator and configured such to pull the accelerator spring within the accelerator with a force sufficient to fire the power jar. When the power jar is in a released state, the linear actuator can also be used to push or pull the entire accelerator and power jar assembly, which in turn can push or pull the target object within the wellbore. The linear actuator can also be used to move the power jar from a released state to a set state.

Abstract: A milling system may be used to remove the portions of a failed valve that is blocking the wellbore. When milling a partially open valve obstructing the wellbore, the target material to be removed may not be present at the central axis of the wellbore causing the target material to not fully surround the milling bit, which may cause the bit to be deflected away from the target during milling reducing milling efficiency. The disclosed milling system may be used to mill out and capture the coupon for any downhole obstruction that does not have any material near the center axis of the wellbore. A first embodiment of the milling sytem may be configured to fully mill out material within the wellbore while a second embodiment may be used to mill out material within the wellbore and further catch the milled material or coupon.
