Systems and methods for non-invasive management of head pain are disclosed. The system includes a headgear configured to be worn on a patient's head. The headgear can include a base and an extension coupled to the base, and a number of therapy devices removably or adjustably attached to the base or the extension. The therapy devices can deliver various modes of therapeutic energy at respective target sites on the head, including neuromodulation of peripheral pain pathways and/or the cerebral cortex, and therapy modalities to facilitate or enhance the neuromodulation effects. The system can include a portable device that enables the user to control the therapy devices on the headgear. The user can use the portable device to optionally access a web-based repository to acquire information about headgear usage from other users, and use that information to guide the programming of the therapy devices.

The present invention relates to a leadframe having a plurality of connections for electrical conductors, a plurality of contacts and at least two outer current bars, and to a connecting socket having a leadframe as well as to a system for transmission of electrical power, in particular from a plurality of solar modules (photovoltaic modules), having a connecting socket such as this. In order to devise a leadframe which occupies as little space as possible, at least one connection (32a-e) is provided for an electrical conductor between the outer current bars (34a, b). This allows the leadframe to have a compact physical shape. The invention is based on the discovery that leadframes are used in the prior art to bridge the distances between predetermined contact separations, offering the possibility of producing, in one stamped part, strip conductors which have different geometries. Furthermore, a connecting socket having such a leadframe is described, and a system for transmission of electrical power using such a connecting socket.

An electrically insulating bobbin surrounds the magnetic core of an inductor. The bobbin includes a number of channels to receive wire for making an inductor. When wire is positioned in the channels, the wire is wound around the inductor core, but insulated from the inductor core and the other turns of wire. Because the bobbin insulates the turns of wire from each other and from the inductor core, bare rope wire can be used to wrap the inductor, resulting in reduced size and weight and improved ease of manufacture.

Prior power converters have utilized discrete components mounted on circuit boards of differing designs. Failure of one or more of the components requires testing each component to determine which is faulty. The faulty component must then be replaced. This results in significant down time for the inverter and can require stocking a large number of specialized boards. In order to overcome these problems, an inverter is assembled using modular circuit boards. Each circuit board includes components mounted on a multilayer substrate and a heat exchanger which cools high power components. When a malfunction of a component occurs, the entire board containing the failed component may be readily replaced so that inverter down time is minimized. The use of modular circuit boards also reduces stocking requirements and inventory costs.

A low pass filter includes a differential mode filter and a common mode filter. The common mode portion of the filter includes at least one inductor and one capacitor, as well as a damping circuit with at least one capacitor. The low pass filter has a reduced weight, which is useful in circumstances in which weight is a significant factor, such as in aircraft.

Film capacitor assembly has a plurality of film capacitive layers for storing an electric charge. The plurality of film capacitive layers have a first metal contact and a second metal contact. A heat sink removes heat from the plurality of film capacitive layers. The heat sink is in thermal conductive communication with at least one of the first metal contact and the second metal contact. A dielectric material is configured to prevent a transmission of electric current through the heat sink from the plurality of film capacitor capacitive layers.
