CRC generation circuitry includes a lookup-table storing N-bit CRC values for M one-hot data frames. N AND gates for each bit of a M-bit data frame receive that bit of the M-bit data frame and a different bit of a N-bit CRC value from the lookup-table corresponding to a position of the bit in the M-bit data frame.

US10402800B2 Image authentication and security system and method
Embodiments of the invention are related to a computer-implemented authentication method and system for authenticating a customer using an electronic device for engaging in a transaction involving a financial institution over a network. Embodiments of the method include capturing an image of the customer engaging in the transaction using an image capturing device integrated with the electronic device and retrieving a stored image of the customer from an authentication database. Embodiments of the invention additionally include comparing, using a comparison algorithm executed by computer processing components, the stored image with the captured image to authenticate the customer and upon authentication, monitoring the captured image during the transaction for an interruption using the computer processing components. The method further includes terminating the transaction if an interruption is detected.
US10402780B2 Service for receiving obsolete web page copies
The state of network-accessible information is preserved by recognizing a reference to a uniform resource locator contained within an electronic file where the uniform resource locator provides an address for content to be preserved. A copy of at least a portion of the information associated with the recognized uniform resource locator is obtained defining relevant content for preservation. A determination is also made as to whether the relevant content of the recognized uniform resource locator has changed since obtaining the copy of the relevant content. If a change is detected, an indication of the change is conveyed, e.g., to a corresponding user.
US10402778B2 System and method for vending vendible media products
A system and method for vending digital video discs is provided. A request is received from a user to complete a rental transaction for a first digital video disc. A database is queried to determine whether a quantity of a set of second digital video discs in a vending inventory exceeds a predetermined threshold. A discount offer notification is presented to the user to rent one of the set of second digital video discs, upon determining that the quantity of the set of second digital video discs exceeds the predetermined threshold. A second request from the user to rent one of the second set of digital video discs is received, and one of the set of second digital video discs is vended to the user.
US10402773B2 System, method, and non-transitory computer-readable storage media for use in delivering items to a customer
A system for use in delivering physical customer items to a customer is described. The system includes a database and a server computer. The database includes customer item lists that include customer item records indicative of physical customer-owned items previously collected from customers. The server computer includes a processor that is programmed to display a website including a plurality of consumer goods and allow the customer to select goods for purchase and delivery. The processor also retrieves a customer item list associated with the customer, displays customer-owned items that are eligible for delivery, and allows the customer to select eligible customer-owned items to be included in a customer delivery order request. The processor also generates and displays a delivery order report including the selected consumer goods, the selected eligible customer-owned items, and a customer specified delivery location for use in assembling and delivering the goods and customer-owned items.
US10402772B2 Cargo geofencing using a vehicle gateway
Electronic components may be integrated in objects used by the trucking industry, such as truck, tractor trailer, cargo, and loading bay. These objects may then communicate with each other and with a gateway device to transmit or receive data or commands. The gateway may be configured to attach to the truck, such as by securing to the truck frame or securing to an interior of the truck cab. The gateway may couple to one or more input devices, and receive sensor data through the one or more input devices. The gateway may execute steps that allow the gateway to perform geofencing to prevent conflict between cargo in the vehicle and cargo in another vehicle or in areas of a loading bay.
US10402771B1 System and method for evaluating drivers using sensor data from mobile computing devices
A network computer system determines a driving ability of a driver using sensor data that is obtained from a mobile computing device of a driver. In some examples, the network computer system determines the driving ability by comparing the sensor data obtained from the mobile computing device of the driver with a set of sensor values that are based at least in part on sensor data obtained from one or more other drivers over a same or similar route.
US10402770B2 Assessing outsourcing engagements
Systems and methods for assessing performance of an outsourcing engagement are described. According to the present subject matter, the system(s) implement the described method(s) for assessing the outsourcing engagement. The method includes identifying at least one Critical Success Factor (CSF) associated with the outsourcing engagement between a vendor and a client based on conducive conditions of outsourcing. The method further includes determining at least one of a plurality of parameters and a plurality of sub parameters associated with the identified at least one CSF, wherein the plurality of parameters and the plurality of sub parameters are inter dependent and effect performance of the at least one CSF. Further, the method includes assessing a value of performance for at least one parameter and at least one sub parameter from amongst the plurality of parameters and the plurality of sub parameters respectively, based on a system dynamics model.
US10402767B2 Systems and methods for monetizing and prioritizing building faults
A fault parameter of an energy consumption model is modulated. The energy consumption model is used to estimate an amount of energy consumption at various values of the fault parameter. A first set of variables is generated including differences between a target value of the fault parameter and the various values of the fault parameter. A second set of variables is generated including differences between an estimated amount of energy consumption with the fault parameter at the target value and the estimated amounts of energy consumption with the fault parameter at the various values. The first set of variables and second set of variables are used to develop a regression model for the fault parameter. The regression model estimates a change in energy consumption based on a change in the fault parameter. Regression models are developed for multiple fault parameters and used to prioritize faults.
