Abstract: A method includes obtaining a first waveform representing an output characteristic with respect to time of a switched-mode power supply. The method further includes removing a high frequency component from the first waveform to generate a modified waveform and determining a stable value of the modified waveform. The method further includes determining an operating parameter of the switched-mode power supply based on the modified waveform, the stable value, or a combination thereof. The one or parameter includes an overshoot value associated with the switched-mode power supply, an undershoot value associated with the switched-mode power supply, or a settling time associated with the switched-mode power supply. The method further includes outputting an indication of the parameter.

Abstract: A transaction card may determine to initiate a mode associated with the transaction card. The mode may be related to locating the transaction card. The mode may be associated with outputting a first signal. The transaction card may determine a manner in which to configure the mode based on a set of parameters. The set of parameters may include a power level of the transaction card, or a strength of a second signal associated with a connection between the transaction card and a device associated with the transaction card. The transaction card may initiate the mode after configuring the mode. The transaction card may determine to terminate the mode based on an indication that the transaction card has been located.

Abstract: In some implementations, a near field communication (NFC) device may determine whether the NFC device is to perform a wireless transaction in a powered mode or an unpowered mode, and may selectively perform the wireless transaction in the powered mode or the unpowered mode based on determining whether the NFC device is to perform the wireless transaction in the powered mode or the unpowered mode. The wireless transaction may be performed using power from a power source internal to the NFC device when the wireless transaction is performed in the powered mode. The wireless transaction may be performed without using power from the power source internal to the NFC device when the wireless transaction is performed in the unpowered mode.

Abstract: A device may monitor, based on location information, a proximity of a vehicle and a third party location of a third party using a set of sensors. The location information may have been received from the vehicle. The location information may identify a location of the vehicle and the third party location. The device may process personal information to determine that an order is associated with the vehicle or an individual associated with the vehicle. The personal information may have been received from the vehicle. The device may receive, via another device associated with the vehicle or the individual, confirmation to complete a transaction for the order. The device may perform a first action to complete the transaction. The device may perform a second action to facilitate a good or a service associated with the order to be delivered to the vehicle in association with performing the first action.

Abstract: The keyless entry system (KES) controls access to a vehicle's doors, trunk, hood, etc., through a keyless entry device (e.g., a key fob) using wireless communication with the vehicle. The technology described here mitigates vulnerabilities in the KES implementation by employing a device configured to suppress a keyless entry command until an additional means of authentication is verified, at which point the keyless entry command is unsuppressed.

Abstract: Systems and methods for providing an interactive multimedia experience are described. For example, a method for providing interactive content includes receiving content data, receiving an indication of a region within a frame of the content data, receiving a scripting event associated with the region, wherein the scripting event specifies an action to be taken responsive to a trigger, receiving a metadata tag or a reference to the metadata tag, the metadata tag associated with the region, and formatting at least a portion of the content data, the indication of the region, the scripting event, and the metadata tag or the reference to the metadata tag in accordance with a file format for transmission.

Abstract: A device may determine that a verification method associated with a transaction card is to be modified from a first verification method to a second verification method. The first verification method and the second verification method may use different types of verification information. The device may provide a set of instructions to the transaction card after determining that the verification method is to be modified. The set of instructions may cause the transaction card to modify the verification method from the first verification method to the second verification method. The device may provide information identifying a modification to the verification method to a transaction backend device to notify the transaction backend device that the verification method associated with the transaction card has been modified from the first verification method to the second verification method.

Abstract: A height adjustable load carrier rack for a vehicle including a base member and an upright leg is disclosed. The base member can be mountable on a vehicle. The upright leg can be configured to be variously coupled to the base member at discrete locations along a length of the upright leg. Additionally, the upright leg can have a demarcated portion including a plurality of position labels, each label can signify individual ones of a plurality of discrete position settings of the upright leg relative to the base member. The base member can be configured to alternately engage with each of the plurality of the discrete locations along the length of the upright leg for height setting the load carrier rack in dependence upon user-selection among the position labels of the demarcated portion of the upright leg.

Abstract: A surface active compound is supplied into contact with an oilfield production fluid that comprises a mixture of water and oil including water soluble organics. The surface active compound comprises at least one alkoxylate chain and at least one end group attached to each of the at least one alkoxylate chain. The surface active compound is supplied into the oilfield production fluid at a dosage rate that is effective to self-associate at interfaces between the water and oil and inhibit the water soluble organics in the oil from entering the water when the oilfield production fluid is depressurized.
