Abstract: A payment card security system includes a payment card provider account system communicatively coupled to a payment card transaction device and a mobile device. The payment card transaction device sends an indication that a payment card is being used to perform a transaction. The payment card provider account system includes processors that receive the indication that the payment card is being used to perform the transaction from the payment card transaction device. The processors also send a notification indicating that the payment card is being used to perform the transaction. The processors further enable authorization of the transaction via the mobile device. In this manner, the payment card security system may prevent or reduce the occurrence of suspicious transactions as they are occurring, rather than waiting until after they have occurred.

Abstract: A tank includes a cone-shaped wall formed of steel and attached between a first dome-shaped surface formed of steel and a second dome-shaped surface formed of steel. The cone-shaped wall attached between the first dome-shaped surface and the second dome-shaped surface defines an oval-shape void of angled corners on the inside surface of tank such that, when a product contained in the tank is displaced, the product is displaced in a torus shaped vortex between the first dome-shaped surface and the second dome-shaped surface.

Abstract: The present disclosure relates to capturing the routing topology of a network (e.g., the Internet covering the entire IPv4 address space). An exemplary method comprises: obtaining a first bit array indicative of a plurality of target IP addresses; assigning a first subset of the plurality of target IP addresses to a first source device; assigning a second subset of the plurality of target IP addresses to a second source device; causing the first source device to transmit a first plurality of probing packets to the first subset of the plurality of target IP addresses and receive a first plurality of returned packets, causing the second source device to transmit a second plurality of probing packets to the second subset of the plurality of target IP addresses and receive a second plurality of returned packets, and generating a data structure representing a routing topology of the network.

Abstract: A modular wall panel including a backer board and a plurality of front boards arranged in a plurality of rows. At least one row of the plurality of rows includes two or more horizontally-adjacent front boards permanently affixed to the backer board. The two or more horizontally-adjacent front boards collectively spanning an entire width of the modular wall panel. At least one row of the plurality of rows includes an enhancement area without a permanently-affixed front board.

The modular wall panel further includes a removable enhancement board configured to be reversibly affixed to the backer board to fill the enhancement area.

Abstract: A sensor for hydrogen in a fluid medium has a chamber for electrolyte with a window which is selectively permeable to hydrogen to allow hydrogen to pass from the fluid medium under test into the electrolyte in the chamber. A plurality of electrodes in contact with the ionic liquid electrolyte are used to observe hydrogen concentration by voltammetry. The electrolyte is an ionic liquid. Applications where such a sensor may be used include a wellbore tool for measuring the content of hydrogen in a subterranean fluid, monitoring of fiber-optic cables for damage by hydrogen, corrosion monitoring, and small-scale process plant where hydrogen is part of a gas stream.
