A method of protecting pin threads of pin ends of tubular members by installing a thread protector on an end of a tubular member.

Abstract: A wireless device receives RRC message(s) comprising: a first maximum value for a preamble transmission counter; and a second maximum value for a second counter. The second maximum value is different from the first maximum value. A control order initiating a random access procedure on a first unlicensed cell is received. A listen-before-talk (LBT) procedure for transmission of a preamble for the random access procedure is performed. Based on the LBT procedure indicating an LBT failure for transmission of the preamble for the random access procedure: a value of the preamble transmission counter is keep the same; and a value of the second counter based on the LBT failure is incremented. The preamble transmission counter counts a number of preamble transmissions. The random access procedure is cancelled based on either the preamble transmission counter reaching the first maximum value or the second counter reaching the second maximum value.

The first sidewall has an opening defined therethrough. The inner tube is positioned in the first interior chamber. The inner tube has a second sidewall defining a second interior chamber. The second sidewall has a longitudinal groove defined therein. The inner tube is configured to extend from and retract within the first interior chamber of the outer tube. The auger bit is positioned in the second interior chamber and is rotatably coupled to the inner tube. The anti-rotation pin is coupled to the first sidewall of the outer tube and extends inwardly into the first interior chamber. The pin engages the longitudinal groove of the inner tube.

A plurality of electrodes acquire biopotential physiological data from the skin of a patient. A controller receives the ultrasound and biopotential physiological data and calculates fetal heart rate (fHR) values, maternal heart rate (mHR) values, and uterine activity (UA) values from the ultrasound and biopotential physiological data.

Abstract: Node apparatus and methods for providing high-bandwidth, low-latency data service over a content delivery network including existing wireline infrastructure. In one embodiment, a network architecture having service delivery over at least portions of extant hybrid fiber coax (HFC) infrastructure is disclosed, which includes a node that enables standards-compliant ultra-low latency and high data rate services (e.g., 3GPP and IEEE Std. 802.11 services). In one variant, an expanded frequency band (e.g., 1.6 GHz in total bandwidth) is used over the coaxial portions of the HFC infrastructure, which is allocated to two or more sub-bands via 802.11ax protocols. The node is used in various network architectures configured to support different use cases such as for providing a small cell service, a distributed antenna system (DAS) at an enterprise premises or a venue, and a redundancy capability of data communication.

Abstract: An audio speaker for projecting sound into a listening space having an on-axis includes a frame supporting at least two drivers radially arrayed in a plane substantially perpendicular to the on-axis. The at least two drivers may be electrically connected to operate in common acoustic phase, substantially the same size, mid-range drivers, and/or may include at least one rearward facing driver. The audio speaker may also include an on-axis driver, or an inner driver positioned substantially at a point where a first line drawn perpendicularly through a face of a first driver of the at least two drivers and a second line drawn perpendicularly through a face of a second driver of the at least two drivers converge. The inner driver may be a high frequency driver, for example, a tweeter, and a face of the inner driver may be substantially perpendicular to the on-axis.

Abstract: A system for storing and generating power is disclosed. The system comprises a first storage reservoir configured to store a first fluid, a second storage reservoir located at a lower elevation than the first storage reservoir and configured to store a second fluid wherein said second fluid has a higher density than the first fluid, and a pump. The pump and the first and the second reservoir are operatively connected such that power is stored by displacing the second fluid in the second storage reservoir by pumping the first fluid from the first storage reservoir to the second storage reservoir and such that power is generated by allowing the pumped first fluid in the second storage reservoir to exit the second reservoir. The first fluid is generally a liquid. In some embodiments, a power recovery device may be employed. In some embodiments, the hydraulic pressure of the low density fluid may be employed to pressurized desalination feed and facilitate desalination.

Abstract: Technologies are generally described for delivery vehicles and containers for en route food product preparation. Modular food product preparation systems that may receive food items and supplies and prepare food product(s) en route such that the food product(s) is prepared by the time the system reaches a delivery destination may include trucks, railway cars, watercraft, and similar vehicles. Food preparation process steps and timing may be determined based on travel information (e.g., delivery destination, routes, etc.), as well as, food item and food product information. An on-board controller may determine the process steps and timing(s) and control operations of robotic devices arranged modularly in a container or vehicle to execute steps of the food preparation process. Alternatively or additionally, the on-board controller may receive instructions from a remote controller. Travel parameters of the vehicle may also be adjusted based on the food preparation process and/or travel information.

Abstract: Distributed grid intelligence can enable a virtual power grid. Multiple consumer nodes can have local power sources, and be coupled to a same point of common coupling (PCC). The consumer nodes can be controlled by distributed control nodes at the consumer nodes. The control nodes control the distribution of power from the local power sources based on local power demand of each respective consumer node, and also based on distribution of power from the other respective control node. Thus, consumer nodes can share power generated locally, but operate independently without the need for central management or a central power plant.
