Abstract: Physical shopping carts can have product detection systems and associate physical shopping carts with mobile computing devices (e.g., smartphones, tablet computing devices, smart watches, wearable computing devices). For example, physical shopping carts can be equipped with one or more product detection systems (e.g., scanners, sensors, cameras) that can electronically tally products that are placed in physical shopping carts. Mobile computing devices can be associated with and mounted on the physical shopping carts to provide a variety of enhanced shopping cart features not possible with conventional physical shopping carts, such as electronically tracking the contents of a shopping cart, checking-out from the mobile computing device (instead of at conventional check-out areas, such as point of sale terminals), and others.

Abstract: A computer system configured to authenticate the identity of a user who is attempting to access a website or conduct a transaction is provided. The system is configured to receive a geographical location associated with the user and to receive the geographical location of a mobile phone associated with the user, and to determine whether the two geographical locations are within an acceptable distance. The system is configured to take into account the accuracy of the mobile phone location.

Abstract: Inferences may be obtained to handle access requests at a non-relational database system. An access request may be received at a non-relational database system. The non-relational database system may determine that the access request uses a machine learning model to complete the access request. The non-relational database system may cause an inference to be generated using data items for the access request as input to the machine learning model. The access request may be completed using the generated inference.

Abstract: Non-relational database operations are invoked to provide results consistent with commands specified in a relational query language. A request to access data in a non-relational database is received that includes one or more commands specified in a query language for accessing data according to a relational data scheme. The request may be evaluated to determine one or more Application Programming Interfaces (APIs) to invoke operations at the non-relational database that provide a result consistent with the commands specified in the query language. The determined APIs are executed and a result returned for the request based on the execution of the APIs.

Abstract: An energy-efficient sequencer comprising inline multipliers and adders causes a read source that contains matching values to output an enable signal to enable a data item prior to using a multiplier to multiply the data item with a weight to obtain a product for use in a matrix-multiplication in hardware. A second enable signal causes the output to be written to the data item.

Abstract: A catheter includes: a body comprising a body side wall, a proximal end and a distal end; a septum extending from the proximal end to the distal end; a first lumen and a second lumen separated by the septum, each lumen forming a mouth at the distal end; first and second slots formed in a portion of the body side wall at the distal end and in fluid communication with the first and second lumens respectively. The first and second slots extend linearly along a direction parallel to a longitudinal axis of the body. The distal end of the body and the septum terminate in a plane perpendicular to the longitudinal axis. The distal end of the body has a substantially round cross section, while the first and second lumens each have a substantially D-shaped cross-section at the distal end. The two slots each have a width that is between 30% and 60% of a longer dimension of the D-shaped cross-section of a corresponding lumen.

The method includes determining, with the processor, whether the change in the value of the physiological parameter over the time period exceeds a change threshold. The method also includes performing an action based on the determination that the change in the value of the physiological parameter exceeds the change threshold.

Abstract: Various embodiments of the present invention relate to a point-of-sale (POS) system, and more particularly, to systems, devices and methods of making secure payments using a mobile device in addition to a POS terminal that may be an insecure payment device exposed to various tamper attempts under certain circumstances. The mobile device is involved in a trusted transaction between a central financial entity, e.g., a bank, and the payment terminal, such that the insecure payment terminal may be further authenticated based on rolling codes, two-way or three-way authentication, or an off-line mode enabled by incorporation of the mobile device. Although either of the mobile device and the payment terminal provides limited security, a POS system incorporating both of them demonstrates an enhanced level of security.

Abstract: The invention provides a method for verifying the identity of an internet user, or for detecting the misuse of an identity, during an on-line transaction. The method involves comparing the geographic location of the transaction to the geographic location of the user's cell phone or other mobile device, and taking a geographically close location relationship between the two as a positive indication of identity. A reasonable travel time between the two locations can be taken into account so as to reduce the incidence of false negatives, and to improve the reliability of positive identifications.
