  • Publication number: 20240379009
    Abstract: This disclosure describes a pickup location determination system that determines a pickup location for a received transportation request by filtering out door points based on various factors and by utilizing a pickup location model to select a pickup location from the filtered door points. For example, the disclosed systems generate door points relative to intersection points within a request radius of a request location associated with a received transportation request. The disclosed systems generate potential pickup locations by filtering out door points that are impractical and/or inefficient based on proximity to other door points, locations relative to venues, locations relative to side streets, and/or locations between parallel road segments (e.g., medians). The disclosed systems further utilize a pickup location model to select a pickup location from the potential pickup locations.

  • Patent number: 11525327
    Abstract: Apparatus and method for securing and sealing a tubular portion to another tubular to provide a liner hanger in oil and gas wells. At the top of the liner string, a sleeve is arranged on the liner to create a chamber therebetween. A port provides fluid access through the liner to the chamber. When fluid is introduced into the chamber the sleeve is morphed to secure it to the cemented casing. A lower fluid pressure is required to morph the sleeve than if the liner itself was to be morphed. Embodiments are provided for securing and sealing arrangements to increase the metal to metal seal and the load capability between the liner string and casing.

  • Publication number: 20220266065
    Abstract: Multi-story retrofitting building escape units. In aspects, the units are prefabricated and may be stacked. In embodiments, water or other fire-deterrent liquid or foam may be stored or delivered in tubular legs of the unit or tubes with in the legs. A hose or other mechanism to apply the water or other liquid is located in one more units. Each unit comprises stairs that link up with stairs on units above or below so occupants can climb down, for example, and emergency personnel can climb up, for example. In aspects, one or more walls of the unit are fire walls or otherwise fire-retardant, fire-proof, or fire-resistant.

  • Patent number: 10969204
    Abstract: The present invention relates to using at least one explosive device to enable rapid and accurate positioning and repositioning of at least one explosive charge for controlled penetration of targets. A penetrator allows effective demolition with minimal explosive load. An attachment collar with magnetic inserts allows quick repositioning of explosive devices. A plurality of explosive devices allows a demolition profile to be rapidly created and adjusted on-site to adapt to changes in structural or environmental conditions.

  • Patent number: 10385993
    Abstract: A method and apparatus for creating a joint between tubulars such as tubing, pipes, casing and liner for location in a well bore. A connector (16) in the form of a sleeve is located over the ends of each tubular (12, 14) and the ends of the tubulars are morphed onto the sleeve to provide a metal to metal seal. In an embodiment the sleeve (16) is morphed onto the ends of the tubulars (12, 14). The connector may also have a profiled inner surface with circumferential grooves (266) and a sectioned locating groove (90) to provide axial and torsional load bearing capacity.

  • Patent number: 9800568
    Abstract: Methods, non-transitory computer readable media, and network traffic management apparatuses that receive a request from a client device to access an application. The request comprises an original certificate. A determination is made when the certificate is valid. Data is extracted from one or more fields of the certificate, when the determining indicates that the user certificate is valid. A delegate certificate comprising the data and signed by a certificate authority trusted by a server device hosting the application is generated. The delegate certificate is sent to the server device. With this technology, network traffic management apparatuses can secure SSL connections using PFS-capable ciphers, while also inspecting payload data in network traffic exchanged between client and server devices in order to provide intelligent services in the network.
