Abstract: A method of thermally protecting a leading edge of a hypersonic system includes saturating an annular primary wick in contact with an evaporator and having a first pore size with a phase change material by means of an annularly-inward secondary wick having a second pore size and being coupled to a liquid line, the second pore size being larger than the first, where a first end of the secondary wick extends into a reservoir and a second end of the secondary wick extends into the evaporator, the second end of the secondary wick having a terminal end. The method includes terminating the liquid line inside of the evaporator, transferring thermal energy from the leading edge into the phase change material, raising the temperature of the phase change material to a phase-change temperature, changing phase of the phase change material, and carrying away heat from the leading edge.

Abstract: Thermoplastic bags with phased deformation patterns are described. In particular, one or more implementations comprise thermoplastic bags with ring rolling, SELFing, or other deformation patterns phased or aligned relative to the sides of the bags. The phased deformation patterns can allow for reducing or eliminating deformation patterns in areas of the thermoplastic bag in which side seals or other seals are formed. Additionally or alternatively, the phased deformation patterns can provide for zones that provide differing properties (e.g., functional or aesthetic). Such zones can vary aligned along a width of the thermoplastic bag and optionally also vary along a height of the thermoplastic bag. The differing zones can provide the thermoplastic bags with phased deformations that provide leak prevention, liquid containment, and other benefits.

Abstract: One or more implementations of a multi-film thermoplastic bag with a grab zone of contact areas positioned in a high-touch area of the bag. For example, the multi-film thermoplastic bag includes one or more regions of a first film in contact with a second film at one or more contact areas. The grab zone regions of one or more contact areas are located in visible and high-touch areas to provide visual and tactile cues of strength and durability. Moreover, the grab zone regions of one or more contact areas serve to distribute pull and lift forces across a wider area in order to avoid common failures in high-touch areas such as over stretching, punctures, tears, and rips.

Abstract: One or more implementations of a multi-film thermoplastic bag with a conjoined hem channel. For example, the multi-film thermoplastic bag includes a multi-film hem channel. Bonds secure the layers of the hem channel together so as to prevent a drawtape from inverting or bunching an inner layer of the hem channel during cinching. The bonds are thus located in a hem channel of a multi-film thermoplastic bag so as to reduce an amount of mechanical engagement between the films of the multi-film thermoplastic bag and another thermoplastic film such as a drawtape. In one or more implementations, a grab zone of the multi-film thermoplastic bag also includes bonds in the form of contact areas to provide tactile and visual cues of strength in the grab zone.

Abstract: Introduced here is a technology that enables a merchant to create customer-targeted, customized communications by use of a merchant platform executing on a financial service system. The merchant platform generates content for communications that is based on a particular customer segment. The customer segment includes one or more groups of customers segmented based on one or more attributes associated with each group of customers. An attribute is determined based on data collected by the financial service system, where the data is related to transaction data of a plurality of merchants.

Abstract: A technique is disclosed for generating an interactive digital receipt on a device associated with a customer, where the receipt offers transaction information associated with a transaction and one or more interactive components. In one embodiment, one or more servers of a payment service generates the interactive digital receipt. The interactive digital receipt includes an interactive feedback component as one of the one or more interactive components. A determination can be made by the one or more servers that feedback was received within a timeframe satisfying a timeframe criterion. Based on determining that the feedback was received within the timeframe, a reward can be transmitted by the one or more servers to the device associated with the customer.

Abstract: A technique is disclosed for providing an interactive digital receipt on a user device, where the receipt offers transaction information associated with a financial transaction and one or more interactive components including an interactive tipping component that allows a customer to add a gratuity amount for the financial transaction. The interactive digital receipt is generated in response to an occurrence of the particular financial transaction. In one embodiment, the interactive tipping component is time-based and is associated with a timeframe that defines a time period for which the customer may submit the gratuity amount. Based on determining that no input to the interactive tipping component has been received within the timeframe, a payment is processed for a transaction amount and a default gratuity amount.

Abstract: Disclosed herein is a technology for automatically triggering delivery of a digital receipt for one or more financial transactions based on a change in location of the user or a time. In at least some embodiments, the technology includes a payment system detecting a change in location of a user or a change in time and determining, based on the change, that a payment transaction has occurred. The payment system then causes presentation of digital receipt for the payment transaction on a mobile device of a customer.

Abstract: Disclosed herein is a technology for automatically triggering delivery of a digital receipt for a financial transaction based on a previously stored electronic address for receiving digital receipts. In at least some embodiments, the technology includes a digital receipt system working in coordination with one or more merchants' POS device to deliver receipts for current transactions based on a previously stored electronic address from past transactions. The first time a user utilizes a payment instrument in a transaction, the system associates and stores the payment-instrument information with an identifier of the user. The next time a transaction is detected that involves the identifier, the system automatically triggers receipt delivery to an electronic address associated with the identifier.

Abstract: In an example embodiment, an azimuth combiner comprises: a septum layer comprising a plurality of septum dividers; first and second housing layers attached to first and second sides of the septum layer; a linear array of ports on a first end of the combiner; wherein the first and second housing layers each comprise waveguide H-plane T-junctions; wherein the waveguide T-junctions can be configured to perform power dividing/combining; and wherein the septum layer evenly bisects each port of the linear array of ports. A stack of such azimuth combiners can form a two dimensional planar array of ports to which can be added a horn aperture layer, and a grid layer, to form a dual-polarized, dual-BFN, dual-band antenna array.

In at least some embodiments, the technology includes a digital receipt system working in coordination with one or more merchants' POS device to deliver receipts for current transactions based on a previously stored electronic address from past transactions. The first time a user utilizes a payment card in a transaction, the system associates and stores a user-provided electronic address with the card. The next time the user utilizes the card in a new transaction, the system identifies the card has been used in a past transaction, determines the electronic address associated with the card, and automatically triggers receipt delivery to the electronic address, regardless of the new transaction being with a same or different merchant than the one in the past transaction.
