63 results about "EFTS" patented technology

EFTS is an acronym for Equivalent Full Time Student. It is a definition used to measure student numbers at New Zealand educational institutions. One EFTS will be made up of more than one part-time students (e.g. two half time students).

Device and method for testing electrical fast transient/burst (EFT/B) immunity of electric energy meter

The invention discloses a device and a method for testing electrical fast transient/burst (EFT/B) immunity of an electric energy meter, and can be used for testing active load, reactive load and high-current load and the like. In the device, a voltage port of a check device of the electric energy meter is connected with an input port of a power filter of a voltage circuit; an output port of the power filter of the voltage circuit is connected with an input port of an EFT test signal generator; a current port of the check device of the electric energy meter is connected with an input port of a power filter of a current circuit; and a pulse port of the check device of the electric energy meter is connected with an input port of a filter of a pulse circuit. The test method comprises the following steps: during the test, a pulse train interference signal generated by the EFT test signal generator enters the electric energy meter under test through the voltage circuit; the check device of the electric energy meter supplies voltage and current signals needed for operation to the electric energy meter under test and obtains error values of the electric energy meter; and the power filter of the voltage circuit, the power filter of the current circuit and the filter of the pulse circuit respectively perform filtering processing on the voltage circuit, the current circuit and the pulse circuit so as to eliminate interference.

Method for improving anti-interference ability of rotary mechanical shaft vibration measurement system

ActiveCN101614582ASolving problems subject to severe electromagnetic interferenceImprove securitySubsonic/sonic/ultrasonic wave measurementVibration measurementElectricity
The invention provides a method for improving the anti-interference ability of a rotary mechanical shaft vibration measurement system. The method comprises the following steps: detecting the rotary mechanical shaft vibration measurement system by conducting the immunity tests on electrical fast transient/burst (EFT/B), so as to determine the part having poor anti-interference ability in the rotary mechanical shaft vibration measurement system; shielding the part having poor anti-interference ability according to the electromagnetic compatibility (EMC) principle; and detecting whether the part having poor anti-interference ability meets the requirements or not according to the immunity tests on EFT/B. The method can detect the part having poor anti-interference ability in the rotary mechanical shaft vibration measurement system on an accurate, timely and effective basis, effectively avoid the tripping operation caused by the automatic protection of the main engine of the power grid due to severe electromagnetic interference, ensure the normal operation of the main engine of the power grid, improve the safety and reliability of the power grid and avoid the huge economic loss caused by the tripping operation of the main engine due to the electromagnetic interference.

Method and system for processing internet payments

ActiveUS10185936B2Safe, sound, and secureFinancePayment circuitsApplication softwareInternet shopping
A system and method for effectuating Electronic Funds Transfer credit messages. The main structural components of the system include a Payment Portal Processor (Web Broker), an Internet Pay Anyone (IPA) Account, a Virtual Private Lockbox (VPL) and an associated Account Reporter, the existing EFT networks, and a cash card for accessing a VPL or IP account. The Web Broker is a software application that provides a secure portal for accessing (linking to) either the user's Demand Deposit Account (DDA) or an IPA account and can be combined with the functionality of a traditional digital Wallet. Consumers use a Web Broker enhanced Wallet to fund their account, shop on the web, pay bills, pay anyone, store electronic receipts and transaction history, and check their recent Web Broker enhanced Wallet activity. The IPA account is a special purpose account with limited functionality for making electronic payments in the form of EFT credit messages. The VPL is a limited function receive only account for receiving electronic payments through the EFT. The Account Reporter is a portal to view transaction history and balance of IPA and VPL accounts, provide online, real-time transaction reports, and to reconciles accounts receivable/purchase records against incoming EFT payment records. A physical card can be associated with either an IPA or VPL account in order to provide PIN debit capability.
