A disclosed anonymous authentication system comprises a group management device, an authentication-subjected user device, a verification device and an authentication-subjected user identification device. A user previously registers a verification key in the group management device such that his signature can be verified. For authentication, the user generates his or her own signature using the authentication-subjected user device, and encrypts the signature using an encryption key of the group to generate authentication data. The verification device authenticates the signature in collaboration with a verification assistant who has a decryption key of the group. The authentication-subjected user identification device that has the decryption key of the group decrypts the authentication data as required to identify a user who is to be authenticated.

Electric vehicle (EV) charging apparatus and methods are described which allow the sharing of charge current between multiple vehicles connected to a single source of charging energy. In addition, this charge sharing can be performed in a grid-friendly manner by lowering current supplied to EVs when necessary in order to satisfy the needs of the grid, or building operator. The apparatus and methods can be integrated into charging stations or can be implemented with a middle-man approach in which a multiple EV charging box, which includes an EV emulator and multiple pilot signal generation circuits, is coupled to a single EV charge station.

In a method for charging a fleet of batteries (110) from a power grid (100), a fleet charge schedule (301) is determined and thereafter individual battery charge schedules are dynamically optimized. The fleet charge schedule (301) for the entire fleet (110) is determined optimizing an energy portfolio balance of an energy portfolio manager. Thereafter, battery charge schedules for individual batteries (111, 112, 113, 114, 115, 116, 117, 118) in the fleet (110) are dynamically optimized such that the battery charge schedules in aggregation realize the fleet charge schedule (301). The battery charge schedules are dynamically optimized in consideration of at least technical specifications of assets in the battery fleet and user constraints of the battery users.

An ambidextrous charging handle for a Stoner-type firearm. The charging handle comprises two separate assemblies, these being an oblong handle that contains a latch assembly and a central shaft member. The parts are joined together by a compound pivoting arrangement in which a combination of the latch assembly and alignment grooves in the central shaft member interacting with slidingly engage a locating flange on the oblong handle, and a pair of pivoting connectors that secure the latch assembly to the oblong handle and the central shaft member independently from one another. The latch assembly includes cam activation via a retention relief cut acting against a fixed minor pivot connector. The second point of retention for the assembly is via a major pivoting connector the combination of which transmits the retraction force applied to the oblong handle on one end of the latch assembly and to the central shaft member through the interconnection of the minor pivot connector located at the proximal end of the latch body.

System and method for enumerating and/or enumerating a device. The device may be a USB portable device which adheres to a first standard, e.g., the USB specification, and may engage in enumeration with respect to a USB hub/USB host device. Where a battery included in the device is sufficiently low, the device may engage in low power enumeration, e.g., to begin charging the device using enumerated power. Low power enumeration may allow the device to enumerate even when the device is incapable of powering on. Additionally, or alternatively, the device may determine whether the hub/host device is capable of providing high power charging. If it is, the device may begin charging the battery of the device using power provided by the hub/host device at a high power level.

High efficiency polymer photovoltaic cells have been fabricated using an optical spacer between the active layer and the electron-collecting electrode. Such cells exhibit approximately 50% enhancement in power conversion efficiency. The spacer layer increases the efficiency by modifying the spatial distribution of the light intensity inside the device, thereby creating more photogenerated charge carriers in the bulk heterojunction layer.

A hybrid construction machine according to the present invention is constructed to drive electric motors (6, 7, 13, 15, 23, 25) by means of power of a power generator (11) to be driven by an engine (10), power of an auxiliary battery (42) and power of a main battery (12) charged with power of the power generator (11). The hybrid construction machine has a switch (43) for switching to drive the electric motors (6, 7, 13, 15, 23, 25) by means of power of at least one of the power generator (11) and the main battery (12) when operating normally and to drive the electric motors (6, 7, 13, 15, 23, 25) by means of power of the auxiliary battery (42) when operating emergency such that the electric motors (6, 7, 13, 15, 23, 25) can not be driven by means of the normal power.

A method for grounding a semiconductor substrate pedestal during a portion of a high voltage power bias oscillation cycle to reduce or eliminate the detrimental effects of feature charging during the operation of a plasma reactor.

The present invention provides a charging method and system for a terminal being accessed through multiple access networks, and a reporting method for a terminal being accessed through multiple access networks. When the terminal establishes one IP Connectivity Access Network (IP-CAN) session with a packet data network through at least one access network, an IP-CAN Type parameter of each access network connection passed through by a data flow of a service accessed by said terminal is sent to a charging subsystem, and said charging subsystem charges differently for data flows passing through different access network connections of said terminal according to said IP-CAN Type parameter.

A secondary battery protection circuit has: a first switch that permits or inhibits charging of a secondary battery by switching a charge conductor between a conducting and a non-conducting state; a voltage detection portion that monitors the voltage of the secondary battery to output an error signal when the voltage is an overvoltage; and a first current path that has one end connected to the positive-side conductor and the other end connected to the negative-side conductor, and through which a current corresponding to the supplied electric power passes. The first current path, other than during charging of the secondary battery, is kept in a non-conducting state and, when the error signal is outputted while the first current path is in a conducting state, is irreversibly brought into a non-conducting state by a current of a predetermined amount or more passing therethrough. The first switch, when the first current path is in a conducting state, permits charging and, when the first current path is in a non-conducting state, inhibits charging. Thus, other than during charging, electric power consumption associated with overcharge protection is reduced, and once an overcharged state occurs, charging never again takes place.

In an electrical powered vehicle including a control device for generating an input/output power command value for a power storage device and a control device for controlling a power conversion device and a rotating electric machine, provided separately, when there is a sudden change in the rotational speed of a rotating electric machine, the input/output power command value of a power storage device intrinsically set by an HV-ECU is corrected corresponding to the change in the rotational speed of the rotating electric machine by a control device MG-ECU detecting the rotational speed of the rotating electric machine, without having to wait for modification of the input/output power command value from the HV-ECU. Accordingly, there can be prevented excessive charging and excessive discharging of a power storage device induced by delay in modifying the input/output power command value caused by transmission delay between control devices when the rotational speed of the rotating electric machine suddenly changes.

A secondary battery includes a battery case configured subject to the configuration of a conventional 9V or 1.5V battery and a battery body and a battery charger mounted in the battery case. The battery charger controls the battery body for charging and voltage output, and provides a USB socket as charging interface and positive and negative electrodes as discharging interface. Thus, the secondary battery is connectable to a USB plug of a cell phone battery charger or computer for charging, and can be installed in an electric product like a conventional battery cell to provide DC power to the electric product. Under the provision of current detection function and voltage adjusting function, the 1.5V secondary battery can be connected in series or in parallel with one or a number of micro resistor-provided virtual batteries to output a voltage subject to its linking arrangement.
