EDI apparatus for demineralizing a liquid flow is assembled in a housing having a cylindrical shape, and includes two metal electrodes, and one or more leafs, each leaf comprising a pair of selectively ion-permeable membranes arranged parallel to each other and spaced apart by spacing elements that allow liquid to flow in the interstitial space between membranes, thus forming an arrangement of dilute and concentrate cells in a desired flow configuration. Spacing elements between membranes, as well as between leaves, can be formed of inert polymer material, ion exchange beads, ion exchange fibers, a combination of two or more these elements, or a porous media incorporating one or more of such elements as an intrinsic part. An inner or central electrode and an outer or perimeter electrode establish a generally uniform and radially-oriented electrical or ionic current between the inner and the outer electrodes, across the helical flow spaces defined by the membrane/spacer windings. One or both electrodes may include a pocket, and the adjacent flow cells lie parallel to the electrode and free of shadowing and field inhomogeneity around a full circumference of the electrode.

Some embodiments of the invention relate to an electrodeionization device that includes comprising a generally cylindrical housing. The cylindrical housing includes a cylindrical inner core and an inner electrode that extends around the inner core. The cylindrical housing includes a leaf arranged as a spiral winding about the inner electrode and an outer electrode that extends about the spiral winding. Active treatment cells are defined by spaces within the spiral winding and by interleaf spaces thereof. One or more sealing bands extend between membranes of the spiral winding to define fluid flow.

A light emitting diode (LED) apparatus for mounting to a heat sink having a front surface with an opening therein is disclosed. The apparatus includes a sub-mount, at least one LED die mounted on the sub-mount, and a thermally conductive slug having first and second areas. The first area is thermally coupled to the sub-mount and the second area has a post protruding outwardly therefrom. The post is operably configured to be received in the opening in the heat sink and to secure the LED apparatus to the heat sink such that the second area is thermally coupled to the front surface of the heat sink. Other embodiments for mounting an LED apparatus utilizing adhesive thermally conductive material, spring clips, insertion snaps, or welding are also disclosed.

An illumination device includes a light source, such as one or more light emitting diodes and a wavelength converting element that is mounted on an opaque support structure. The support structure includes an aperture with which the wavelength converting element is aligned so that the converted light is emitted through the aperture. The wavelength converting element may be a rigid structure, such as a luminescent ceramic and the aperture may be a hole through the support structure. The support structure may hold the wavelength converting element so that it is physically separated from the light source, or alternatively, the support structure may place the wavelength converting element in physical contact with the light source.

Provided are systems, methods and techniques for establishing a pricing structure for reserving a resource. An option is selected from among a plurality of available options with respect to delivery of a resource at a specified future time, and then the selected option is presented to a customer. Each of the plurality of options includes: (i) a reservation price at which the customer may reserve the resource, and (ii) a compensation amount that must be paid if the resource is not delivered at the specified future time. The specified future time may be either a point in time or an interval of time.

Methods are disclosed for determining the relative binding affinities of molecules for their binding partner. One type of molecule is an antibody, which has an antigen binding partner. Antibodies are tested for binding against limited dilutions of antigen. Antibodies that bind to the most dilute antigen concentrations are determined to have a higher relative binding affinity for the antigen than antibodies that only bind to more concentrated antigen preparations.

The relevance of documents is automatically determined based upon a weighted tree. Terms considered to be relevant are assigned to the leaf nodes of a tree data structure. A location can also be specified in a leaf node, indicating where in a document the term must appear to be considered relevant. Internal nodes of the tree are assigned operators (e. g. , add, maximum or minimum). The connections between nodes are assigned weights. A relevance value for a given document is calculated as a function of occurrence in the document of terms assigned to leaves, operators assigned to internal nodes, and weights assigned to the associated node connections. Weighted trees can be used to process search queries. Documents with high relevance scores calculated against the tree can be returned to a user as the results to a query.
