A stimulator for stimulating the leg or other parts of the body e.g. the leg in a patient with drop foot is provided, the stimulator being controlled by e.g a foot switch but being reliable in use and therefore commanding acceptance by users. The foot switch has to work in adverse environmental conditions and is subject to repeated use so that its characteristics vary with time. The invention provides a functional electrical stimulator for attachment to the leg that has adaptive characteristics and comprises first and second electrodes for attachment to the leg to apply an electrical stimulus, a foot switch for sensing foot rise or foot strike, a circuit responsive to said foot switch for generating stimulation pulses; and means forming part of said circuit for responding to changes in the resistance characteristics of said switch means by adjusting a corresponding response threshold of said circuit.The invention also provides a two-channel stimulator that offers various possibilities for controlling the signals to be supplied to different muscle groups. For example, means may be provided defining a signal pathway between the first and second channels so that the supply of stimulation pulses in one of said first and second channels can be controlled by the state of switch means associated with the other of said first and second channels. In a further embodiment means defining a signal pathway between the first and second channels is arranged so that the supply of stimulation pulses in one of said first and second channels can be controlled by the state of activity of the other of said first and second channels. In a yet further embodiment the first channel has means arranged to cause the stimulation pulses to time-out after a predetermined period and the second channel having no or disabled timing means so that supply of stimulation pulses is continuous in a predetermined state of limb position responsive switch means associated with that channel. The two-channel stimulator can be used e.g., to treat bilateral dropped foot.

A method and system for tracking and providing an audit trail for off-line smart card transactions includes storing information representing a monetary transaction in a permanent memo on an smart card microprocessor and holding the transaction amount in escrow until the stored information is transmitted from the smart card, for example, at an on-line terminal, to a host on-line system for logging to a tracking system. The monetary transaction includes a transaction with an off-line device, such as another smart card. The escrowed transaction amount represents, for example, a load transaction to one of the smart cards and an unload transaction to other smart card. Once the memo is deleted from the respective smart cards, the load values of the respective smart cards are incremented or decremented by the transaction amount. Alternatively, the smart cards may be provided with a card-to-card key, in which case, a permanent memo is stored only on the receiving smart card.

A feedback device for measuring balance related information, and for producing a stimulation of the skin that encodes that information in a way that is useful to the wearer of the device. At least one sensor detects balance information and transmits at least one balance information signal to a signal processing subsystem. The signal processing subsystem converts the received balance information signal into at least one stimulation control signal. The signal processing subsystem then transmits the stimulation control signal to at least one stimulator, which provides stimulation to a wearer of the device reflecting the stimulation control signal received from the signal processing subsystem.

Aging, injury and/or other pathologies of joints, especially weight bearing joints, contribute to changes in natural biomechanics. Deviations from optimal biomechanics lead to acceleration of the natural history of joint pathology and ultimately osteoarthritis. A Magnetic Vector Control System made up of an assembly of magnetic field sources can be disposed at or near a joint typically on or in adjacent bones of the joint, on one side of a first mechanical axis that creates a torque or moment about a second different axis of the joint, that intersects the first mechanical axis, to decrease the joint reactive force at the joint surface or equivalently substantially shift the first mechanical axis to a new or preferred position.

The inventive technology, in certain embodiments, may be generally described as a solar power generation system with a converter, which may potentially include two or more sub-converters, established intermediately of one or more strings of solar panels. Particular embodiments may involve sweet spot operation in order to achieve improvements in efficiency, and bucking of open circuit voltages by the converter in order that more panels may be placed on an individual string or substring, reducing the number of strings required for a given design, and achieving overall system and array manufacture savings.

An inter-gaming operator (IGO) server and method is described. The IGO server receives gaming and non-gaming transactions from gaming operator systems, comprising gaming platforms and merchants associated with each gaming operator system. Each gaming operator system issues its own casino crypto currency (C3) for use in gaming and non-gaming transactions. For each transaction that is processed by the IGO, the IGO debits and credits user accounts in accordance with the particular C3 involved in each transaction. Each transaction is further maintained by generating one or more crypto-blocks, each crypto-block comprising a cryptographically-encoded version of all or a portion of the information in each transaction received by the IGO server. Because the IGO server is coupled to multiple gaming operator systems, the IGO server may be used to detect illicit wagering activities that heretofore could not be detected.

Determining server capabilities during a discrete time period, or interval, allows for more efficient processing of client requests. Updating a proportional server capability load balancing information encoding at intervals allows a load balancer to handle client requests without the overhead of determining current server capabilities. Decision-making can be reduced to quick selection of one of a group of servers without considering the server's capability, since the server's capability has previously been considered when collecting the load balancing information.

Executing a FOTA (firmware over the air) method in a LoRa network having low throughput and low power. the transceivers used in the end nodes and in the LoRa gateway are capable of selecting a certain frequency channel and deactivating the LoRa mode. If the spread-spectrum LoRa mode is deactivated, both transceivers at the end node and the gateway function instead using a basic FSK (frequency-shift keying) modulation scheme. This modulation scheme is capable of providing a higher data rate at the expense of reducing the “path balance,” which indicates how much attenuation the transmitted signal may sustain while still being able to be decoded at the receiver. When using the FSK modulation scheme at a high data rate, a FOTA method may be easily carried out, since the end node must have its receiver activated only for a short time.

There is provided a technique of preventing occurrence of a shift in white balance even when the ratio of a dark area is greater than the ratio of a bright area as in the case of a night view. A white balance gain calculator calculates white balance gains for an image from color of pixels whose luminance levels are at equal to or greater than a reference luminance level among all pixels of an image. When the ratio of dark pixels whose luminance satisfies a predetermined condition, among all pixels of the image, is equal to or greater than a reference ratio, a correction coefficient calculating section determines a correction coefficient from at least one of factors; namely, image-capturing sensitivity corresponding to an image, the ratio of dark pixels, and firing/non-firing of flash light; and instructs the white balance gain calculator to make a correction to the white balance gain in accordance with the correction coefficient.
