20140232301 | METHOD AND DEVICE FOR CHARGING A BATTERY OF AN ELECTRICAL DRIVE USING COMPONENTS OF THE ELECTRICAL DRIVE - The invention relates to a multi-stage charging device for a battery of a battery operated electrical motor. The multistage charging device comprises a buck converter, an intermediate circuit and a boost converter in order to generate a suitable direct charging current from a (one or three-phase) alternating current provided by a power connection. According to the invention, components of the electrical drive are used for the boost converter and the intermediate circuit: the electrical motor functions as an intermediate circuit and the drive converter functions as a boost converter. According to the invention, the coupling of the electrical motor to the network-side buck converter occurs so that at least half the charging current flows through at least one of the at least three coils of the electrical drive. The invention further relates to a corresponding method and to a corresponding use of the drive components. | 08-21-2014 |
20150236614 | ENERGY SUPPLY SYSTEM AND METHOD FOR ACTUATING COUPLING DEVICES OF AN ENERGY STORAGE DEVICE - The invention relates to an energy supply system having an energy storage device. The energy storage device has a plurality of energy storage modules that are serially connected in at least one energy supply branch, each comprising an energy storage cell module having at least one energy storage cell, and a coupling device having coupling elements configured to selectively switch the energy storage cell module into the respective energy supply branch, or to circumvent same, and comprising a plurality of driver devices, each dedicated to one of the energy storage modules, and coupled to one of the energy storage modules, and which are configured to actuate the coupling elements of the coupling devices according to a driver signal. The energy supply system further comprises a control device, which is coupled to the driver devices by way of a control signal line, and which is configured to emit a control signal to the driver devices by way of the control signal line, which is provided with a physical control signal parameter, into the value of which a control mode for the driver devices is coded. The driver devices are configured to receive the control signal, and to generate the respective driver signal subject to the value of the control signal parameter, and a control mode assignment that can be predetermined. | 08-20-2015 |

20110225059 | POS SALES TRANSACTION SAFETY NET - A method for monitoring a register is provided which comprises (a) providing a register having associated therewith (i) an electronic journal which resides on a hosting server separate from the register, and which receives digitally transmitted records of all transactions occurring at a register, and (ii) a secure, nonvolatile memory device which stores sales transaction data for the register; (b) determining whether the memory device associated with the register has sales transactions with a date within a specified date range; (c) if the memory device does not have sales transactions with the specified date range, then marking the memory device as having been examined for transactions in the specified date range; (d) if the memory device does have sales transactions with the specified date range, then determining whether the transaction data stored therein corresponds to the transaction data stored in the register's electronic journal for the specified date range; (e) if the transaction data stored in the memory device corresponds to the transaction data stored in the register's electronic journal, then marking the memory device as having been examined for transactions in the specified date range; and (f) if the transaction data stored in the memory device does not correspond to the transaction data stored in the register's electronic journal, then marking the memory device as having been examined, initiating a data recovery process and generating a notice of the discrepancy. | 09-15-2011 |
20130085876 | POS Sales Transaction Safety Net - A method is provided for monitoring a register having an electronic journal associated therewith which resides on a hosting server separate from the register, and which receives records of all transactions occurring at the register. A secure, nonvolatile memory device stores sales transaction data for the register. If the memory device does not have sales transactions within a specified date range, then the memory device is marked as having been examined for transactions in the specified date range. If it is determined that the memory device does have sales transactions within the specified date range, then the memory device is marked as having been examined for transactions in the specified date range if the transaction data stored therein corresponds to the transaction data stored in the register's electronic journal for the specified date range; otherwise, a data recovery process is initiated, and a notice of the discrepancy is generated. | 04-04-2013 |
