Abstract: Systems and methods for monitoring a fleet of self-driving vehicles are disclosed. The system comprises one or more self-driving vehicles having at least one sensor for collecting current state information, a fleet-management system, and computer-readable media for storing reference data. The method comprises autonomously navigating a self-driving vehicle in an environment, collecting current state information using the vehicle's sensor, comparing the current state information with the reference data, identifying outlier data in the current state information, and generating an alert based on the outlier data. A notification based on the alert may be sent to one or more monitoring devices according to the type and severity of the outlier.

Abstract: Introduced here is a technology for automatic notification of an invoice based on identification of a customer identifier included in transaction data received from a point-of-sale (POS) device of a particular merchant. Transaction data for a transaction occurring at the merchant POS device between a customer and the first merchant can be transmitted from the POS device to server(s) of a payment processing service. The transaction data can include a customer identifier. The POS device can receive invoice data from the server(s) associated with an unpaid invoice that is associated with the customer identifier and a historical transaction with the first merchant or a second merchant. The POS device can cause presentation, on a display of the POS device, an invoice payment invitation for the customer to make a payment on the unpaid invoice.

Abstract: The present disclosure relates to systems, non-transitory computer readable media, and methods for detecting and providing a digital notification of whether a ridership error exists. For instance, a ridership error detection system identifies a transportation match between a requestor device and a provider device. The ridership error detection system determines one or more sets of provider-requestor consistency signals from the requestor device and the provider device across ride stages. For instance, the ridership error detection system analyzes location signals, IMU signals, audio signals, local wireless signals indicating distances between the requestor device and the provider device, and other signals to determine whether a ridership error exists. The ridership error detection system provides digital notifications to the provider device and the requestor device based on the ridership error determination.

Abstract: Some examples include a payment processing system that receives transaction information of transactions performed between a plurality of merchants and a plurality of buyers, and receives an indication of an invoice generated by a first merchant and payable by a purchasing entity. The payment processing system may determine terms for payment of the invoice based on at least one of: (a) transaction information received from a first computing device of the first merchant configured as a point of sale terminal; (b) transaction information of at least one related merchant determined based on at least one of: a geographic location related to the purchasing entity, or a business type related to the purchasing entity; (c) transaction information of the purchasing entity; or (d) one or more characteristics of the invoice. The payment processing system transmits the terms to the first merchant, and may receive an acceptance from the first merchant.

Abstract: A method of targeting, which involves capturing a first video of a scene about a potential targeting coordinate by a first video sensor on a first aircraft; transmitting the first video and associated potential targeting coordinate by the first aircraft; receiving the first video on a first display in communication with a processor, the processor also receiving the potential targeting coordinate; selecting the potential targeting coordinate to be an actual targeting coordinate for a second aircraft in response to viewing the first video on the first display; and guiding a second aircraft toward the actual targeting coordinate; where positive identification of a target corresponding to the actual targeting coordinate is maintained from selection of the actual targeting coordinate.

Abstract: A reusable pour spout system that may be attached to different container types to dispense different substances, including course and fine granular materials and liquids. A port component has a proximal tubular end and a flange that is larger than the tubular end. The flange further includes a hole-cutting structure adapted to pierce the wall of a container, with a cutting edge adapted to form a hole in the container when the port component is rotated by a user after piercing. This positions the flange within the container with the tubular end exposed to receive a nut that traps the wall of the container between the nut and the flange. A cap is provided to seal off the port. The tubular end of the port component, the nut, and the cap may all be threaded. Different structures to enhance cutting and sealing are disclosed along with preferred method steps.

Abstract: Regioselectively substituted cellulose esters having a plurality of pivaloyl substituents and a plurality of aryl-acyl substituents are disclosed along with methods for making the same. Such cellulose esters may be suitable for use in films, such as +A optical films, and/or +C optical films. Optical films prepared employing such cellulose esters have a variety of commercial applications, such as, for example, as compensation films in liquid crystal displays and/or waveplates in creating circular polarized light used in 3-D technology.

Abstract: A gas and liquid separation system could be said to have a passage with an inlet connected to receive a mixed gas and liquid flow. An air separation tube extends into the passage at a location downstream of where the inlet is connected with an upstream tube end upstream in the passage relative to a downstream tube end. The upstream tube end provides an obstruction to the mixed gas and liquid flow, to cause separation of the gas from the mixed gas and liquid flow. A liquid tube is connected to the passage at a location downstream of the air separation tube.

Abstract: Introduced here is a technology for automatic notification of an invoice for a customer based on identification of a customer identifier included in transaction data received from a point-of-sale (POS) system of a particular merchant (“the invoice technology”). The notification can include a promotion to provide an incentive to the customer to pay the invoice. The notification can be presented on a display of the POS system. Alternatively, the notification can be presented in a receipt for the transaction conducted at the POS system, where that receipt can be transmitted for display at a user device of the customer. For example, the receipt can be in the form of an email message or a text message. Upon notification of the invoice, the customer can submit a payment for that invoice (“invoice payment”) in exchange for the promotion.

Abstract: A distributed safety lockout system for a vehicle, such as a recreational vehicle (RV), that includes a plurality of networked devices communicatively coupled via a communications network, and that is configured to implement a method for controlling an electromechanical operation of an electromechanical device based on a safety lockout condition determined through use of a consensus protocol in which a safety lockout status is agreed upon by the networked devices. The safety lockout status may be escalated by a safety lockout condition detection device that detects a safety lockout condition, such as movement of the RV. The safety lockout status may be de-escalated through a network contention mode of the consensus protocol in which each of the networked devices agree to de-escalate the safety lockout status.

Abstract: Methods, systems, and non-transitory computer readable storage media are disclosed for generating region-based metrics for provider devices based on movement of provider devices through various regions and transportation requests within the various regions. For example, the disclosed system provides an accumulating regional metric map including one or more regions with pins indicating corresponding region-based metrics to a provider device. The disclosed system can then determine whether the provider device passes through (or otherwise enters) a region with a pin and determine the corresponding region-based metric of the region for the provider device. In response to generating a transportation match between the provider device and a requester device, the disclosed system can provide a notification of the region-based metric to the provider device in connection with the transportation match.
