Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for intelligently restricting transportation changes based on signals in a dynamic transportation matching system. For example, the disclosed systems can analyze signals associated with transportation of a requestor by a vehicle of a provider to determine whether a transportation-change request is indicated. In response to determining that a transportation-change request is indicated, the disclosed systems can prevent a transportation change to a destination, route, or waypoint and generate a restriction notification. The disclosed system can also provide the restriction notification to at least a provider client device in response to determining that it is safe to do so.

Abstract: A resonant frequency adjustor for mounting onto an exhaust pipe of an exhaust system of a vehicle adjusts the resonant frequency(s) of the exhaust pipe to minimize or control vibration transmitted to the vehicle and/or to tune the sound emitted by the exhaust system. The resonant frequency adjustor includes a base mounted to the exhaust pipe, an isolator attached to the base, a stud attached to and extending from the isolator, and a mass located on the stud. A gross adjustment of the vibration of the exhaust pipe may be achieved by varying the location of the resonant frequency adjustor on the exhaust pipe. A fine adjustment of the vibration of the exhaust pipe may be accomplished by adjusting the position of the mass on the stud.

Abstract: A system and method is provided to measure a pressure or other characteristic at a source (e.g. a hydraulic power supply) and in or near a downhole tool. A comparison of the measurements is then made to verify that the system is operating according to desired parameters. In specific applications, the comparison can be made to ensure the supply of hydraulic fluid is reaching the downhole tool.

Abstract: An adjustable headrest assembly for a seat includes a frame, a front bracket adjustably moveable toward and away from the frame, and a linking mechanism for guiding the movement of the front bracket. A rack having teeth is mounted to the frame. A locking member is rotatably coupled to the linking mechanism and selectively engages the teeth. The locking member is rotatable between a positioning mode and a return mode. In the positioning mode, the front bracket is adjustable away from the frame to discrete extended positions. In the return mode, the front bracket is adjustable to a retracted position. A biasing device is mounted to the locking member. The biasing device biases the locking member into engagement with the teeth when the biasing device is in the positioning mode and biases the locking member toward disengagement with the teeth when the biasing device is in the return mode.

Abstract: A headrest assembly that is rotatable to various positions includes a support defining a horizontal axis. A shell is rotatably mounted to the support. Notches are disposed on the support, and each notch is associated with one of the positions. A lever is mounted to the shell and has a locking portion rotatable about the pivot axis and partially disposed in one of the notches to prevent movement of the shell. An actuator is mounted to the shell and rotates the locking portion of the lever about a pivot axis in a direction transverse to the horizontal axis. The actuator moves the locking portion out of one of the notches to allow the shell to rotate about the horizontal axis. Furthermore, the actuator moves the locking portion into one of the notches to prevent the shell from rotating about the horizontal axis.

Abstract: The foldable headrest assembly includes a first and second support and a first and second paddle. A first and second plate extending from the supports and supported by the paddles rotate in unison about a first axis (A1) from an upright to a forwardly folded position. A lock lever rotatably supported by the first plate rotates about a second axis (A2) between a locked position and an unlocked position. A first biasing member (FBM) is disposed between the plates and a second biasing member (SBM) is supported by the first plate engaging the lock lever. The FBM rotatably biases the supports about the A1 toward the forwardly folded position and the SBM rotatably biases the lock lever about the A2 toward the locked position in a common rotational direction as the rotation of the supports about the A1. A release mechanism for rotating the lock lever is also disclosed.

Abstract: One aspect of the present invention is a system and method to measure a pressure or other measurement at a source (e.g. a hydraulic power supply) and in or near a downhole tool and compare the measurements to verify that, for example, the supply is reaching the tool. Another aspect of the present invention is a system and method in which a gauge is positioned within a packer. Yet another aspect of the invention relates to a gauge that communicates with the setting chamber of a packer as well as related methods. Other aspects and features of the system and method are also described. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: A replication defective herpes virus vector is described. The replication defective herpes virus vector has a deletion of at least a fragment of a UL29 gene that is replaced with a heterologous sequence encoding an antigen from a specific infectious disease agent. The vector can express said antigen. Prior HSV infection did not diminish the magnitude or the durability of the IgG antibody response generated by preferred replication-defective HSV-1 vectors. A method of inducing in a mammal an immune response against a specific infectious disease agent also is described. A recombinant replication defective mutant Herpes Simplex Virus as a vaccine is administered to a mammal to elicit in the mammal an immune response against the infectious disease causing agent.
