Abstract: Disclosed is a battery cell system, which provides regulation service to the grid, as well as the battery being used as part of an uninterruptible power supply (UPS). Part of the capacity of the storage batteries may be used for regulation service, while maintaining a reserve of battery capacity to provide the UPS supply if required. An advantage is that the battery installation can be more effectively monitored as it is more regularly being charged and discharged.

Abstract: A power conversion and control system includes a power battery group and an energy battery group. The energy battery group is connected to a DC converter, the DC converter output being connected to a bus, and the power battery group is connected directly to the bus, so that operatively the voltage of the bus is variable. The bus may be connected to an inverter for output to a load, via a transformer. A difference in response time is provided between the inverter and the DC converter. The bus may be connected to the grid via a grid rectifier, and to the load via a load inverter.

Abstract: A high speed multi-lane serial interface and method for constructing frames for such an interface are provided. Frames are constructed for transmission on a multi-lane serial interface. For each of a plurality of transmit channels, packets are fragmented into fragments. Meta-frames are generated having a size defined by a constant meta-frame length×number of lanes, each frame having a meta-frame separator and a payload. Per-transmit channel flow control information is received. Each payload has a plurality of bursts, each burst comprising a burst control word and an associated data burst, the burst control word identifying one of said transmit channels to be transmitted on the associated data burst, each data burst comprising one of the fragments for the transmit channel identified in the associated burst control word. The channels to transmit in a given meta-frame are selected as a function of the received flow control information.

Abstract: Methods, apparati, and computer-readable media for securely loading a software module over a communications network from a software provider (SP) (101) onto a tamper resistant module (TRM) (103).

Abstract: A realtime electronic communications system utilizes an instant-messaging server. A first computer includes a first instant-messaging client. The first client is adapted for logging the first computer in to the server, and communicating to the server connecting information of the first computer. A second computer includes a second instant-messaging client. The second client is adapted for logging the second computer in to the server, and communicating to the server connecting information of the second computer. An external device is operatively connected to the second computer. Respective connecting information of the first and second computers is utilized for effecting realtime peer-to-peer communication between the first and second computers, whereby the first computer interfaces with the external device in realtime.

Abstract: This invention allows a provider of a service over a network to upgrade from passwords to security tokens. Tokens are supplied to clients in a generic state and initialised at the client sites, thereby saving the provider the costs of initialisation of tokens for different clients at a central site.
