Abstract: A method for electronic device virtualization and management includes transmitting a signal to a server from a client. The signal is initiated by a user of a user interface of the client. The user interface of the client presents at least two devices to the user, which the user may interact with. The signal may include a power cycling instruction directed to at least one of the devices. When the server receives a communication back from the at least one device, it may send the information to the client, where the user interface may be updated in response to the communication. The devices may be controlled with other instructions, such as scheduling instructions, firmware update instructions, and configuration backup instructions. If a power device is virtualized, it may be controlled on a port-by-port basis.

Abstract: Disclosed herein are system, method, and computer program product embodiments for detecting duplicates with exact and fuzzy matching on encrypted match indexes using an encryption key in a cloud computing platform. An embodiment operates by determining a match rule index value upon reception of a new record. The embodiment encrypts the match index rule value using the customer's encryption key and a deterministic encryption method and stores the encrypted match rule index value. Duplicate detection may be later performed by using the same deterministic encryption method to determine a cypher text for a candidate entry and comparing the ciphertext to the stored encrypted match indexes.

Abstract: In a method for superimposed conveyance of data and electrical power, a first switch can cycle to convey the electric power and data from a first device. Binary digits of the data from the first device can be represented by transitions, of a voltage at a node of a second device, between a first voltage and a second voltage. A second switch can cycle to convey data from the second device. Binary digits of the data from the second device can be represented by transitions, of a current through a component of the first device, between being less than a threshold and being greater than the threshold. A voltage regulator of the second device can provide, in response to the voltage at the node being within a range of voltages that includes the first voltage and the second voltage, the electrical power to one or more components.

Abstract: A metamaterial-based phase shifting element utilizes a variable capacitor (varicap) to control the effective capacitance of a metamaterial structure in order to control the phase of a radio frequency output signal generated by the metamaterial structure. The metamaterial structure is configured to resonate at the same radio wave frequency as an incident input signal (radiation), whereby the metamaterial structure emits the output signal by way of controlled scattering the input signal. A variable capacitance applied on metamaterial structure by the varicap is adjustable by way of a control voltage, whereby the output phase is adjusted by way of adjusting the control voltage. The metamaterial structure is constructed using inexpensive metal film or PCB fabrication technology including an upper metal “island” structure, a lower metal backplane layer, and a dielectric layer sandwiched therebetween.
