Abstract: In one embodiment, a computer-implemented method includes collecting data from at least one component of a micromobility vehicle. The method includes analyzing the data to determine whether a condition of the micromobility vehicle corresponds to an unsafe condition. The method includes determining, based on analysis, that the condition of the micromobility vehicle corresponds to the unsafe condition. The method includes activating an immobilization lock on the micromobility vehicle to immobilize a wheel of the micromobility vehicle responsive to determining that the condition of the micromobility vehicle corresponds to the unsafe condition.

Abstract: Disclosed herein are systems and methods that include a keypad that detects button presses using deflection sensing. The keypad may be a keypad of a camera such as an endoscopic camera head. A button press may be detected based on an amount of deflection of a material. The deflection of the material may be caused by force from a user's finger on a button of the keypad. The material may be located proximate to a sensor, which outputs a sensor signal indicating the amount of deflection of the material. Aspects of the disclosure comprise a controller that identifies an amount of deflection, compares the amount of deflection to a signal threshold, and determines whether a button has been pressed based on the comparison.

Abstract: A pump comprising a housing, a motor disposed within the housing, and an impeller driven by the motor and configured to create a low-pressure region to draw fluid into the housing. The pump further includes a battery electrically coupled to the motor and configured to selectively supply electrical current to the motor and a controller operable to control operation of the motor.

Abstract: In one embodiment, a computer-implemented method comprises sending, by a client application to an email server, a first request to access an email message; receiving, in response to the first request, email message data, the email message data specifying a note identifier of a note; sending, to an application server, a second request to access the note based on the note identifier; receiving, in response to the second request, note data that defines, at least in part, content of the note; controlling a display device to display, based at least in part on the email message data and the note data, the email message and the note in-line with the email message.

Abstract: Metal-support interaction offers electronic, geometrical and compositional effects to tune and maneuver catalytically active sites. Here we report the first example of a reactive metal support interaction (RMSI) between Pt and various MXenes, which are two-dimensional (2D) metal carbides, nitrides, or carbonitrides. The invention thus provides intermetallic Pt/MXene nanoparticle catalysts comprising platinum and MXene moieties. Pt3Ti and Pt3Nb intermetallic nanoparticle catalysts were prepared by RMSI of Pt nanoparticles supported on Ti3C2 and Nb2C MXenes. The intermetallic structures were verified by XAS, ARSTEM, and XPS. Experimental analysis showed that the extent of alloy formation is temperature dependent. Kinetics analysis revealed that in contrast to Pt/Al2O3, Pt supported by Nb2CTx exhibits weaker CO adsorption and the alloy-MXene interface shows enhanced ability of H2O dissociation for a water gas shift (WGS) reaction at 300° C.

Abstract: An electro-hydraulic actuator is operable in any orientation without changing components. The electro-hydraulic actuator includes a reservoir for containing a hydraulic fluid, a bladder within the reservoir for containing a compressible gas, a pump fluidly connected to the reservoir with one or more inlet/outlet ports, and an electric motor drivingly coupled to the pump. The bladder has an inlet/outlet port configured to communicate with a gas source external to the reservoir for adjusting the amount of compressible gas within the bladder. The bladder may also be configured within the reservoir in a manner that prevents the bladder from obstructing fluid flow to the pump inlet/outlet, and that can also prevent fluid from becoming trapped by the bladder and therefore inaccessible to the pump.

Abstract: A hydraulic cylinder has a main body portion with a piston bore extending in a longitudinal direction of the main body portion from a first end to a second end of the main body portion. A first cylinder mounting bracket extends in the longitudinal direction and has at least one aperture disposed along the length of the bracket for locating and securing the hydraulic cylinder to a structure. A manifold mounting portion extends in the longitudinal direction of the main body portion and has a first fluid passageway extending in the longitudinal direction from the first end to the second end. Thus, a manifold can be mounted to the manifold mounting portion at one of a plurality of different positions and/or orientations along the length of the hydraulic cylinder while allowing fluid communication between a fluid port of the manifold and the fluid passageway of the manifold mounting portion.
