Abstract: An electronic device displays a messaging user interface of a messaging application, including a conversation transcript of a messaging session between a user of the electronic device and another user, a message-input area, and a representation corresponding to the other user. In response to detecting a first user input corresponding to the representation of the other user, a menu is displayed that contains an activatable menu item for initiating a payment action with the other user. While displaying the menu, in response to detecting a second user input corresponding to the activatable menu item for initiating a payment action with the first other user, a user interface configured to initiate sending of payment to, and/or requesting payment from, the first other user is displayed.

Abstract: A stimulus and sensor device can include a body comprising a resilient material, the body being configured to be struck by a bat, multiple light sources longitudinally spaced apart along the body, and multiple motion sensors longitudinally spaced apart along the body. A method of evaluating batting performance can include activating one of a series of light sources spaced apart along a body, and measuring motion of the body due to being struck after the activating step.

Abstract: A release tool can include an inner mandrel, an electric motor assembly, and an engagement member. The inner mandrel is displaceable by the electric motor assembly between a position in which the inner mandrel supports the engagement member and prevents separation of portions of the release tool, and another position in which the engagement member is not supported by the inner mandrel and separation of the portions of the release tool is permitted. A method of separating portions of a release tool in a well can include transmitting an electrical signal to an electrical motor assembly of the release tool, displacing an inner mandrel of the release tool in response to the transmitting, and separating the portions of the release tool after the displacing.

Abstract: A cable head can include an upper connector configured to connect the cable head to a wireline, a lower connector configured to connect the cable head to a well tool, and a weak link configured to transmit tensile force between the upper and lower connectors. The weak link can include a shock absorber connected in series with a weak point. A method of connecting a wireline to a well tool can include securing the wireline to an upper end of a weak link, and securing the well tool to a lower end of the weak link. The weak link includes a wire rope, and end links secured at respective opposite ends of the wire rope. One end link includes a weak point. A weak link for use with a cable head can include a weak point and a shock absorber connected in series with the weak point.

Abstract: A wind turbine apparatus has a tower and a plurality of blades rotatably mounted relative to the tower. Each of the plurality of blades has a reflective media on a surface thereof.

Abstract: A device for separating and extracting suspended solids and particles from a fluid is shown. The device can include a hydro-cyclonic process unit, a variable geometry vortex process unit, a reverse coalescence and flocculation process unit and a fixed geometry vortices separator process unit. The fluid to be treated can enter the device through a fluid inlet and travel and recirculate through the several process units. The process units can collectively induce vorticose separation of the fluid and separate suspended solids and particles within the fluid. The suspended solids and particles can then be extracted from the device via one or more extraction fluid outlets. After the desired amount of suspended solids and particles has been removed, the processed fluid can be discharged from the device.

Abstract: An apparatus can include a cable head assembly with a cable head stinger connected to a weak link, and a release assembly including a bushing that radially outwardly supports a dog in engagement with an internal groove formed in an outer housing. A method can include connecting a bottom hole assembly to a wireline, the connecting including connecting the wireline to a cable head stinger of a cable head assembly; deploying the wireline and bottom hole assembly into the well; applying a tensile force to the wireline, thereby breaking a weak link of the cable head assembly; and then displacing the cable head stinger into engagement with a bushing of the release assembly, thereby permitting a dog to displace radially inwardly out of engagement with an internal groove in the release assembly.

Abstract: A tool assembly for performing a wellbore operation including an actuatable tool, a location device, and on-board controller are together dimensioned and arranged to be deployed in the wellbore as an autonomous unit. The actuatable tool, such as a perforating gun having associated charges, perforates a wellbore along a selected zone of interest. The location device, such as casing collar locator, senses the location of the actuatable tool based on a physical signature provided along the wellbore. The on-board controller or micro-processor is configured to send an activation signal to the actuatable tool when the location device has recognized a selected location of the tool based on the physical signature. The tool assembly further includes a multi-gate safety system. The safety system prevents premature activation of the actuatable tool.
