Abstract: A lead-acid battery is disclosed. The lead-acid battery has a container with a cover and includes one or more compartments. One or more cell elements are provided in the one or more compartments. The one or more cell elements comprise a positive electrode, the positive electrode having a positive substrate and a positive electrochemically active material on the positive substrate; a negative electrode, the negative electrode having a negative substrate and a negative active mass on the negative substrate, wherein the negative active mass comprises a leady oxide, a synthetic organic expander, a very fine particle barium sulfate, and plurality of conductive carbons; and an absorbent glass mat separator between the positive plate and the negative plate. Electrolyte is provided within the container. One or more terminal posts extend from the container or the cover and are electrically coupled to the one or more cell elements.
Abstract: The present disclosure relates to systems, methods, and computer-readable media for optimizing selection of a cached execution plan to use in processing a parametric query. For example, systems described herein involve training a plan selection model that makes use of machine learning to identify an execution plan from a set of pre-selected execution plans based on predicted cost of executing a query instance in accordance with the selected execution plan (e.g., relative to predicted costs of executing the query instance using other pre-selected execution plans). This application describes features related to lowering costs associated with selecting the execution plan in a way that will continue to be more accurate overtime based on training and refining the plan selection model.
Abstract: Systems and methods are provided for cooling a drilling mud in a drilling operation. In aspects, the disclosure includes drawing the drilling mud from a last active volume mud tank of a plurality of active volume mud tanks and conducting the drilling mud to a heat-exchanger apparatus and then returning the drilling mud to the last active volume mud tank. In other aspects, the disclosure includes a variable frequency drive (“VFD”) for controlling a pumping rate of an electrically driven pump for the drilling mud, wherein the VFD is capable of adjusting the pumping rate for pumping of the drilling mud through a heat-exchanger apparatus. In further aspects, systems and methods are provided that use a tube-and-shell heat exchanger. The aspects are independently capable of providing improved efficiency. These and other aspects are preferably used in combination for greater efficiency.
Abstract: Disclosed herein are system, method, and computer program product embodiments for categorizing customer complaints on social media using a model trained on customer voice calls or chats with agents. Additionally, users interested in monitoring regulatory compliance issues based on customer complaints can receive notifications regarding complaints that are linked to regulatory topic areas, without the need to manually scan vast numbers of social media postings.

Abstract: Systems, methods, and computer program products for recording and monitoring pain are disclosed. A device may record a date and time corresponding to a pain entry, a pain type corresponding to the pain entry, and a pain intensity corresponding to the pain entry. The device may further record a pain location on a body corresponding to the pain entry. The device may also display the pain entry. In various embodiments, the device may display a graphical pain representation superimposed over the pain location on the body. The device may also read an input encircling the pain location on the body. The device may further display a plurality of pain entries in a plot relative to time.
Abstract: An agricultural implement for applying fertilizer beneath the surface of the soil. The implement has a main frame for connecting the agricultural implement to agricultural equipment. A swing arm is pivotally connected to the main frame. An adjustable actuator interconnects the swing arm to the main frame to control the movement of the swing arm with respect to the main frame. A pair of discs are mounted to the free end of the swing arm for rotation with respect to the swing arm. The discs are offset mounted with respect to one another and are angled outwardly with respect to the direction of travel of the implement. The discs form grooves for receipt of fertilizer. Fertilizer tubes are mounted adjacent the discs and terminate behind the discs with respect to the direction of travel. The fertilizer tubes deposit fertilizer in the grooves formed by the discs. A furrow closer is attached to the main frame to close the groove opened by the discs.
Abstract: A ready hanger automatically pivots about a hinge to raise an arm of the hanger up to make it easy to find the empty hangers in a crowded closet. A hinge is configured between the hook portion and hanger portion and a weighted portion creates an imbalance in the hanger portion to cause it to rotate about the hinge. The hanger portion rotates to produce an inclined end that extends up above the clothes and other hangers in the closet. The weighted portion may be configured proximal an extended end of the arm extension to produce torque to cause the hanger portion to rotate. The hanger portion rotates automatically to an incline angle from horizontal of at least 15 degrees or more. A spring element may be configured between the hook portion and hanger portion to produce the torque required to rotate the hanger portion and produce the inclined end.
Abstract: Novel tools and techniques are provided for implementing network experience shifting, and, in particular embodiments, using either a roaming or portable hypervisor associated with a user or a local hypervisor unassociated with the user. In some embodiments, a network node in a first network might receive, via a first network access device in a second network, a request from a user device to establish roaming network access, and might authenticate a user associated with the user device, the user being unassociated with the first network access device. Based on a determination that the user is authorized to access data, content, profiles, and/or software applications that are accessible via a second network access device, the network node might establish a secure private connection through a hypervisor or container communicatively coupled to the first network access device to provide the user with access to her data, content, profiles, and/or software applications.
