A financial tender transfer system allows a transferor to transfer credit or make payment to a transferee by debiting the credit card of the transferor and crediting the credit card of the transferee. The financial tender transfer system gives the transferee immediate access to the transferred money and ensures the transferor's credit card is valid. Neither party needs to give their credit card number to the other, so security is preserved. Any amount of value up to the full credit line of the transferor can be transferred to the transferee.

A method of authenticating a user to use a system includes using a provider token to generate a random value. The token generates a derived key based at least in part on a token-provided salt value and a user-provided password.

An energy transfer system comprises a transmitter array, an energy transfer controller, a receiver array, a charging module. The transmitter array is embedded in a roadway and the energy transfer controller is coupled to the transmitter array. The receiver array and the charging module are part of a mobile vehicle. The transmitter array and the receiver array each include a plurality of coils.

A low latency streaming system provides a stateless protocol between a client and server with reduced latency. The server embeds incremental information in media fragments that eliminates the usage of a typical control channel. In addition, the server provides uniform media fragment responses to media fragment requests, thereby allowing existing Internet cache infrastructure to cache streaming media data. Each fragment has a distinguished Uniform Resource Locator (URL) that allows the fragment to be identified and cached by both Internet cache servers and the client's browser cache. The system reduces latency using various techniques, such as sending fragments that contain less than a full group of pictures (GOP), encoding media without dependencies on subsequent frames, and by allowing clients to request subsequent frames with only information about previous frames.

Secondary resonant pickup coils (102) used in loosely coupled inductive power transfer systems, with resonating capacitors (902) have high Q and could support large circulating currents which may destroy components. A current limit or "safety valve" uses an inductor designed to enter saturation at predetermined resonating currents somewhat above normal working levels. Saturation is immediate and passive. The constant-current characteristic of a loosely coupled, controlled pickup means that if the saturable section is shared by coupling flux and by leakage flux, then on saturation the current source is terminated in the saturated inductor, and little detuning from resonance occurs. Alternatively an external saturable inductor (1101, 1102) may be introduced within the resonant circuit (102 and 902), to detune the circuit away from the system frequency. Alternatively DC current may be passed through a winding to increase saturation of a saturable part of a core. As a result, a fail-safe pickup offering a voltage-limited constant-current output is provided.

The controller determines the load condition on the power receiving side based on threshold information received from the power receiving device and load condition detection information from the load condition detection circuit.

A synchronized data transfer system including storage processor nodes, a backbone communication switch, multiple titles subdivided into subchunks and distributed across the nodes, a user process executed on a first node, a transfer process executed on a second node, and a management process executed on a management node. The user process sends a timestamped read request to request a corresponding subchunk. The transfer process sends a message to the management process for each received read request, where each message identifies source and destination nodes. The management process broadcasts transmit commands to initiate sequential transmit periods, receives the messages, and selects from among the received messages to ensure that each node sends or receives only one subchunk during each transmit period. The management process sends a transmit request for each selected message, and the transfer process sends a subchunk identified by a transmit request in response to the transmit command.

A power pick-up for an Inductively Coupled Power Transfer (ICPT) system is provided having a resonant pick up circuit. The natural frequency of the pick-up circuit may be varied by controlling the conductance or capacitance of a variable reactive in the resonant circuit. The load being supplied by the pick-up circuit is sensed, and the effective capacitance or inductance of the variable reactive component is controlled to vary the natural resonant frequency of the pick-up circuit to thereby control the power flow into the pick-up to satisfy the power required by the load.

Methods are provided for embedding auxiliary information in a host content signal which reduce the memory, bandwidth and computational complexity of the embedding and transmission systems. In one embodiment, a first reduced-scale signal is produced which corresponds to the host content embedded with a first logical value and producing a second reduced-scale signal corresponding to the host content embedded with a second logical value. A first set of segments from the first reduced-scale signal may be combined with a second set of segments from the second reduced-scale signal in a pre-defined manner to produce a composite embedded host content. Thus the storage and transmission requirements of the watermarking system are reduced to having to deal with only the original content plus two reduced-scale signals.

An inductive power transfer system (1) comprises a primary unit (10) operable to generate an electromagnetic field and at least one secondary device (30), separable from the primary unit, and adapted to couple with the field when the secondary device is in proximity to the primary unit so that power can be received inductively by the secondary device from the primary unit without direct electrical conductive contacts therebetween. The system detects if there is a substantial difference between, on the one hand, a power drawn from the primary unit and, on the other hand, a power required by the secondary device or, if there is more than one secondary device, a combined power required by the secondary devices. Following such detection, the system restricts or stops the inductive power supply from the primary unit. Such a system can detect the presence of unwanted parasitic loads in the vicinity of the primary unit reliably.
