  • Patent number: 11392920
    Abstract: The present disclosure relates to a mobile computing device that is configured to secure a purchase transaction between a customer and merchant, and facilitate self-checkout between the user and any of several merchants. The system provides a payment processing network that achieves secure transactions free from fraud, while also having low fees. The system is based on establishing a relationship between a merchant's bank and a customer's bank, prior to a purchase transaction by the customer. The customer may then authorize their own bank to push funds to the merchant's bank in order to purchase goods or services using their smartphone, without the need to share any financial information between the user and merchant themselves. The smartphone is further configured to draw from multiple merchant product databases so that the customer may self-checkout, without the need to use a merchant-specific app, all within one app-linked system for payment and shopping.

  • Patent number: 11393238
    Abstract: A system for controlling an operation of a vehicle when a passenger is secure in a child car seat can receive data from one or more sensors within a passenger compartment of the vehicle, analyze the data to determine that a passenger is secure in a child car seat within the vehicle, and cause the vehicle to switch from operating in a first mode of operation, such as a bidirectional mode, to a second mode of operation, such as a unidirectional mode. The system may determine a direction of travel for the vehicle based on a pose of the passenger within the vehicle. The system can cause the vehicle to improve the riding experience of the passenger, such as by outputting media content to the passenger or modifying the operational characteristics of the vehicle, for example, by rocking the vehicle from front to back and/or side to side.

  • Patent number: 11389225
    Abstract: A radio frequency (RF) current sensor for remotely activating a smoke evacuation device in an electrosurgical system includes a sensor body with a cable interfacing sidewall and a retaining member. The cable interfacing sidewall and the retaining member define a retention pocket for receiving a cable communicating RF current. The RF current sensor additionally includes a sensor element for detecting RF current in the cable and a sensor cable in electrical communication with the sensor element. The RF current sensor can operate in at least two modes, depending on whether the cable communicates RF current to a monopolar or bipolar electrosurgical instrument, but regardless of the operation mode, the sensor cable can communicate an activation signal and a current signal derived from the detected RF current to the smoke evacuation device, which activates or adjusts the period of time and/or the smoke evacuation flow rate of a vacuum source.
