Abstract: A waveguide rotary joint includes a first waveguide member comprising a first waveguide portion, and a second waveguide member comprising a second waveguide portion, the second waveguide member rotatably connected via a curved circumferential path to the first waveguide member, wherein the second waveguide portion is adjacent to the first waveguide portion to define a first split rectangular waveguide. A first waveguide input/output port is communicatively coupled to the first waveguide portion, and a second waveguide input/output port is communicatively coupled to the second waveguide portion. Relative rotation between the first waveguide member and the second waveguide member changes an angular length of the first waveguide connecting the first waveguide input/output port to the second waveguide input/output port.

Abstract: Techniques directed to performing a cardless payment transaction based on a geographical location of a mobile device are described. The techniques may include displaying a user interface with a list of merchants that are proximate to the mobile device. User input may be received to enable automatic check-in with a merchant. The techniques may further include determining that the mobile device is within a particular distance to the merchant and sending an indication to carry out a cardless payment transaction with the merchant.

Abstract: A method of processing a transaction between a customer and a merchant includes receiving from a mobile device of the customer or from another device of the customer an indication of consent to perform a cardless payment transaction with the merchant, receiving from the mobile device an indication that the customer is within a predetermined distance of the merchant, after receiving both the indication of consent and the indication that the customer is within the predetermined distance, sending to a computer system of the merchant an indication of the presence of the customer and personal identifying information for the customer, receiving data indicating a transaction between the customer and the merchant, and submitting the transaction to a financial service for authorization.

Abstract: A downhole indicating device includes a collet body and a slidable collet comprising a protrusion and surrounding and slidable along a length of the collet body between a low snap position and a high snap position. In the low snap position, the protrusion is depressible under a low snap force, and in the high snap position, the protrusion is depressible under a high snap force with the low snap force being less than the high snap force.

Abstract: A multi-polarized continuous transverse stub (CTS) antenna includes a first feed network operative to at least one of receive or transmit a signal having a first polarization, and a second feed network different from the first feed network and operative to at least one of receive or transmit a signal having a second polarization different from the first polarization. At least one parallel-plate region is defined by a first plate structure and a second plate structure spaced apart from the first plate structure, where a first coupling structure connecting the first feed network to the parallel-plate region and a second coupling structure connecting the second feed network to the parallel-plate region. A common aperture is arranged on one side of the parallel-plate region, wherein wavefronts produced by the first and second coupling structures and propagated within the parallel-plate region radiate to free-space through the common aperture.

Abstract: Facilitating generation of standardized tests for touchscreen gesture evaluation based on computer generated model data is provided. A system comprises a memory (110) that stores executable components and a processor (112), operatively coupled to the memory, that executes the executable components. The executable components can comprise a mapping component (102) that correlates a set of operating instructions to a set of touchscreen gestures and a sensor component (104) that receives sensor data from a plurality of sensors. The sensor data can be related to implementation of the set of touchscreen gestures. The set of touchscreen gestures can be implemented in an environment that experiences vibration or turbulence. Further, the executable components can comprise an analysis component (106) that analyzes the sensor data and assesses respective performance data and usability data of the set of touchscreen gestures relative to respective operating instructions.

Abstract: A computer-implemented method for facilitating a merchant transaction comprises providing a list of one or more merchants that are in geographic proximity to a geolocation of a payer, and receiving a request from the payer to conduct a transaction with a merchant among the one or more merchants. The request can be received by a computer system programmed to facilitate the transaction. The transaction can then be processed with the aid of the computer system. A tip selection, which can include a tip amount, can be applied to the transaction. In some cases the tip selection is received from the payer as a selectable option. In other cases, the tip selection is automatically applied to the transaction without involvement from the payer during or upon the termination of the transaction.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating geofences. One of the methods includes receiving, at a mobile device, a signal emitted by a merchant device associated with a merchant. If the signal is emitted by a merchant device associated with a merchant and the distance between the mobile device and the merchant device satisfies a threshold, a notification is provided on the mobile device indicating proximity of the merchant associated with the merchant device.

Abstract: A security control system is provided that works as an extra layer of defense as a way to prevent an “attack” that is initiated by modifying either the “jump” or the “return” addresses or both. The principal behind the security control system is to “monitor” the addresses to which the processors would jump, interrupt or return, and identify when these addresses are modified in a manner that does not comply with the normal execution of the processor. In order to do that the security control system uses existing structures in multi-core processors and even anticipates the creation of additional structures to expedite and improve such control.

Abstract: Various embodiments are related to apparatuses and methods for paying for a financial transaction using a proxy object. The proxy object can be associated with multiple payment accounts, for example accounts associated with credit cards and debit cards. A consumer can present the object to a payee to make a payment, and the payee can use a device to obtain information from the object. For example, when the proxy object is a proxy card similar to a credit card, the payee can use a card reader to read information from the magnetic stripe of the proxy card. The information can be transmitted to a financial system, and the financial system can communicate with a computer system that can select a payment account associated with the proxy card to use for the payment. The financial system can process the payment using the selected payment account.

Abstract: The folding playard consists of a frame and a fabric enclosure mounted on the frame. The frame is composed of an array of scissoring tube pairs making up the sides of the structure. The fabric enclosure has the same number of sides as the frame and an integral bottom floor. To lock the playard in the “in use” position, a plastic hook clip, which is connected to the bottom floor fabric and the top of the structure is engaged. This strap ensures the tubes are locked in the “in use” position and the structure cannot collapse.
