Abstract: A contactless payment device including a wireless communication device; a power source; a processor coupled to the power source; an accelerometer communicatively coupled to the processor and the power source; and an actuator communicatively coupled to the wireless communication device and the processor. The actuator is configured to activate the wireless communication device when the actuator is set in a closed state, and deactivate the wireless communication device when the actuator is set in an open state. The processor is configured to receive an incoming signal from the accelerometer; determine whether the incoming signal corresponds to a pre-programmed signal corresponding to an enabling gesture; and set the actuator in the dosed state for a time interval, when the incoming signal corresponds to the enabling gesture.

Abstract: In order to predict plant stresses at a localized level, data feeds from many sensor types can be fused and analyzed to create a synthetic sensor estimating plant water stress, predicting microclimatic conditions, and performing localized plant disease and pest modeling. To make this affordable, an array of low-cost, lower precision sensors can be used. Sensor fusion is used to improve the accuracy of each sensing element by using machine learning to fuse data from the other sensing elements in the array. Additionally, machine learning can create a “synthetic sensor” replicating the output of high-cost and maintenance intensive sensing devices by using machine learning to replicate their output.

Abstract: Using inductive currents to wirelessly charge a device via a device connected to a power source. This inductive charging may result when a first mobile device recognizes a second mobile device via a wireless connection (e.g., Bluetooth, Bluetooth Low Energy (BLE), Near-Field Communication (NFC), or the like). An application stored on the first mobile device may recognize a second mobile device by transmitting an advertising packet when the first mobile device is connected to a power source. An advertising packet may be received by the second mobile device and the second mobile device may transmit a response to the advertising packet in order to generate a connection between the first and second mobile devices. The response may include data such as, connection strength, response time, connection preferences, and the like. Upon detection and connection, the second mobile device may be wireles sly charged by the first device via inductive charging.

Abstract: A transaction card may monitor an amount of electric current induced in a first near-field communication (NFC) component of a transaction card. Electric current may be induced in the first NFC component when the first NFC component is within an electromagnetic field generated by a second NFC component of a transaction terminal. The transaction card may dynamically activate one or more output components associated with the transaction card based on the amount of electric current induced in the first NFC component. The one or more output components may indicate whether the transaction card can communicate with the transaction terminal. The transaction card may perform an action related to completing a transaction after determining that the amount of electric current induced in the NFC component satisfies a first threshold. The first threshold may indicate that the transaction card can communicate with the transaction terminal.

Abstract: An electronic device, such as a dynamic transaction card having a chip, an applet, and a cryptographic coprocessor performs secure firmware and/or software updates, and performs firmware and/or software validation for firmware and/or software that is stored on the electronic device. Validation may compare a calculated checksum with a checksum stored in the device. If a checksum calculated for a firmware and/or a software application matches a stored checksum, the transaction card may operate normally. If a checksum calculated for a firmware and/or a software application does not match the stored checksum, the transaction card may freeze all capabilities, erase the memory of the transaction card, display data indicative of fraud, and/or the like.
