Abstract: A payment handling system operates to handle payments for the cost of an open ticket transaction in which incremental authorization operations are performed. The payment handling system receives items to add to the open ticket, payment instruments for paying the cost of the open ticket or adjustments to any bill splitting arrangement throughout the life of the open ticket. As items are added, payment instruments are received, and/or adjustments are input, the amount allocated to the one or more payments instruments may be updated. Incremental authorization values are determined for some or all of the payment instruments. When the amount allocated to a payment instrument exceeds the incremental authorization value, an authorization of the instrument is attempted and a new authorization value is determined. At the end of the interaction, the open ticket is closed and payment is executed.

Abstract: A mobile point-of-sale (POS) terminal for processing a financial transaction between a buyer and a merchant includes a first mobile computing device running a register application configured to receive payment information from the buyer for facilitating a transfer of funds from the buyer to the merchant, and a payment object reader coupled with the first mobile computing device. The payment object reader includes a wireless communication interface, a processor configured to determine the proximity of the second mobile computing device using signal strength of a signal received via the wireless communication interface. In response to the proximity of the second mobile computing device crossing a threshold, the payment object reader transmits a request to the second mobile computing device to connect with the first mobile computing device. The first mobile computing device and the second mobile computing device may then communicate payment and/or transaction information to complete a POS transaction.

Abstract: Systems and methods for separating metallically augmented non-magnetic objects are provided herein. Systems may include a conveyor for translating refuse along a path, the refuse comprising non-magnetic objects and metallically augmented non-magnetic objects, and a magnetic force generator extending along at least a portion of the conveyor and generating a magnetic force that causes the metallically augmented non-magnetic objects to remain in contact with the conveyor as the metallically augmented non-magnetic objects traverse along the path and as the non-magnetic objects are removed from conveyor.

Abstract: Examples, methods and systems described herein may include determining, by a payment processing system, whether a second payment mechanism may be used to perform a payment transaction when a first payment mechanism is preferred and/or when the first payment mechanism has failed. Determining to use the second payment mechanism can be based on (i) an analysis of a communication status indicator received from a point-of-sale (POS) terminal that indicates which payment mechanisms are capable of communicating with the POS terminal, (ii) data received from the POS terminal that is associated with a read of a payment object, and/or (iii) an allowance criterion.

Abstract: A payment terminal may receive a request to process electronic payment information from a payment card in a swipe mode. The payment terminal may provide an opt-in request. If a user accepts, the payment terminal may receive a payment transaction request and electronic payment information of a swipe payment type from the payment card at a swipe interface. The payment terminal may determine whether the payment card is a chip card and generate a swipe mode processing indicator. The swipe mode indicator may allow processing of electronic payment information using procedures for the swipe payment type. The payment terminal may transmit the swipe mode processing indicator and electronic payment information to a payment server from a communication interface of the payment terminal, and may receive a payment approval response based on the swipe mode processing indicator.

Abstract: A method of fabricating a truss section is provided. Cross-bars are connected to truss chords, each cross-bar extending between an associated pair of truss chords, the cross-bars located adjacent to an end of the truss section. An end plate is coupled to the cross-bars after the cross-bars have been connected to their truss chords. The end plate has apertures and ear portions. Each ear portion extends from the end plate to cover an end of a truss chord. The apertures align with corresponding apertures in an end plate of an adjacent truss section. The apertures receive connectors that also pass through the corresponding apertures to fixedly couple the two truss sections. The method may also include coupling a rig bar between truss chords. The rig bar may receive a removable coupler to suspend the truss from above.

Abstract: In some examples, methods and systems may process one or more payment transactions between a merchant and a buyer by detecting buyer's communication device as an instrument to approve or reject a payment transaction in offline mode. The method includes detecting at least one transaction activity associated with a payment system, establishing a communication channel between the POS terminal an RF communication device in proximity to the POS terminal to obtain at least one device characteristic of the communication device, related to the operational or physical features of the communication device; generating a digital fingerprint based in part on the obtained device characteristic and the information related to received payment object; determining whether the digital fingerprint substantially compares to an existing fingerprint in a database and if the existing fingerprint is substantially similar to the digital fingerprint, rejecting the payment transaction through presence of the communication device.

Abstract: There is disclosed a modular, linearly actuated high-pressure pump for use in various applications with high-pressure fuel systems, in particular liquid cryogenic fuels such as Natural Gas, Hydrogen, Nitrogen and Argon (LNG/LH2/LN2/LAR). The pump utilizes linear actuation which smooths out the power profile. There are no dynamic seals which prevents failure from leakage. The primary benefit of a smooth, no pulse output and lack of dynamic seals is a longer life of the pump. Marine fuel systems that utilize cryogenic LNG are a primary application.

Abstract: In some examples, a merchant device at a point of sale (POS) location may present information to a merchant in a first language preferred by the merchant, and may present information to a buyer in a second language preferred by the buyer. The merchant device may switch between the different languages in response to detecting a change in the physical orientation of a display. For instance, in a first orientation in which the display is viewable from a merchant direction, the merchant device may present information in the language preferred by the merchant. When the orientation of the display is changed to a second orientation in which the display is viewable from a buyer direction, the merchant device may present information in the language indicated to be preferred by the buyer. Various techniques may be used for determining the preferred language of a particular buyer.

Abstract: A payment handling system may operate to handle payments for the cost of a transaction in which one or more devices operate in an offline mode. The payment handling system may allow for merchant devices to make modifications to local versions of an open ticket while in an off-line mode. When a merchant device subsequently enters an online mode, the systems and techniques may operate to reconcile differences between the local versions of the open ticket.

Abstract: A truss section is provided that includes a plurality of chords and a solid rig bar. The rig bar extends between two of the chords and is fixedly coupled at one end to one of the two chords and at its other end to the other chord. The rig bar includes an aperture that can receive a removable coupler that is operable to suspend the truss from above. First and second pluralities of cross-bars extend between pairs of chords, the first cross-bars located adjacent to one end of the truss section and the second cross-bars adjacent to the other end. First and second end plates are fixedly coupled to the cross-bars. The end plates each have a plurality of apertures and a plurality of ear portions. The ear portions extend to cover the ends of the chords. The pluralities of apertures are configured to align with apertures in an adjacent truss section and to receive connectors to fixedly couple the truss sections together.

Abstract: Techniques and arrangements for providing payment protection to merchants who utilize point-of-sale (POS) devices that are configured to conduct transactions in both online and offline modes. In an offline mode, a POS device of a merchant stores information regarding a payment instrument used in a transaction between the merchant and a customer, for later sending of the information to a payment service for authorization of the payment instrument when the POS device is in the online mode. The described techniques protect the merchant in a situation where a payment instrument used in an offline transaction is later declined, by providing payment to the merchant for at least a portion of the cost associated with the transaction.

Abstract: The expansion of a network by converting the network from a 2-stage folded Clos network to a 3-stage folded Clos network can be cost prohibitive. The system and methods described herein relate to a hybrid network topology. More particularly, the disclosure describes a hybrid topology having internal switches configured in a multidimensional topology configuration. Each of the internal switches are connected to the network hosts with a folded Clos topology.

Abstract: In some examples, methods and systems may institute technical fallback by determining, by a payment processing system, and based on analysis of the communication status indicator and the data obtained when a magnetic stripe of the payment object is introduced in magnetic stripe object reader, whether the payment object was swiped while an EMV object reader was communicatively coupled to the POS terminal. If the magnetic stripe of the payment object was swiped while the EMV object reader was connected to the POS terminal, the payment processing system extracts a transaction count indicating a number of times the customer has attempted to insert a chip of the payment object into the EMV object reader prior to swiping magstripe. By comparing the transaction count with a threshold count, the payment processing system authorizes the payment transaction as a technical fallback transaction if the transaction count is greater than the threshold count.

Abstract: Techniques and arrangements for transitioning point-of-sale (POS) devices between online and offline modes. In some instances, the techniques instruct a POS device to transition from an online mode to an offline mode based on a volume of transactions on the POS device within a certain time period, based on an increase in the rate of transactions occurring on the POS device, or based on anticipating a rise in the number of transactions on the POS device for other reasons.

Abstract: A downhole measurement tool configured to be run through a bore includes a source and a 3-component receiver. The source is configured to emit a source signal, which may be a compressional or a shear wave, into a volume of material surrounding the bore. The source signal propagates through the volume of material surrounding the bore and reflects off of features disposed within the volume of material surrounding the bore. The three-component receiver includes a first element, a second element, and a third element. The first element is oriented in a first plane, orthogonal to an axis of the bore, and receives a first component of the set of reflections of the source signal. The second element is oriented in the first plane, orthogonal to the first element, and receives a second component of the set of reflections of the source signal. The third element is oriented parallel to the axis and receives a third component of the set of reflections of the source signal.
