Abstract: A compact electromagnetic coupler for use with digital transmission system is described. In one embodiment, the apparatus includes a first transmission structure, including a portion having a geometry. A second transmission structure having the geometry and positioned proximate the portion of the first transmission line structure having the geometry to form a compact electromagnetic coupler with the first transmission structure a geometry of the electromagnetic coupler to enable placement within a footprint of a standard card connector. The compact electromagnetic coupler so formed enables reconstruction of the logical state and timing of a signal transmitted along the first transmission structure.

Abstract: An integrated circuit transformer. A substrate supporting multiple layers of materials of an integrated circuit is provided with a first metallization layer comprising a first set of turns of a primary winding of a transformer, and a second set of turns of a secondary winding of the transformer. A insulation layer is deposited over the first metallization layer, and a second metallization layer bearing a second set of turns of the primary winding, and an optional third set of turns of a second secondary winding. A via connection connects one end of the first set of turns of the primary winding to the second turns of the primary winding located on the second metallization layer. The result is a transformer structure where the primary winding is provided on multiple layers and each secondary winding is confined to a single layer.

Abstract: A method and apparatus to improve modulation efficiency. A symbol is created in which the relative position of a second pulse is a symbol period encode at least one bit. The symbol is transmitted across a communication channel. The one or more bits modulated by the position of the second pulse are recovered such that high bit rate communication may occur without channel compensation.

Abstract: Methods and apparatus are provided for multi-user communication of multimedia content including dividing a client's scene into a non-shared and shared parts. In a disclosed embodiment, the non-shared parts of a scene may be organized into one or more single-user nodes with which other clients cannot interact. The shared parts of the scene are organized into one or more multi-user group nodes. These multi-user group nodes enable multiple clients to access the same scene and to interact with its shared content. Each multi-user group node is an extension of a Group node. In addition to the functionality provided by a single-user group node, a multi-user group node wraps its children with control mechanisms required for supporting multi-user communication. These control mechanisms may be provided as boolean exposed fields that act as switches to control initiation of interaction, update control, privacy, and object accessibility.

Abstract: An assembly (for example, an assembly in the form of an interposer that is distinct from a motherboard and from the devices that communicate with the motherboard) includes electromagnetic couplings. Each of the electromagnetic couplings couples signals being communicated between a device and a bus. Each of the electromagnetic couplings is connected to (a) an associated bus connector to provide connections of the couplings to the bus, and (b) an associated device connector to provide connections of the couplings to the device.

Abstract: In accordance with one aspect of the invention, set forth is a system and method for administering electronic markets which include encrypted electronic content. A system provided access to a communication network having an electronic server system configured to permit communication among a community of users, where the server system is used to host the electronic markets. A distributed configuration and administration system permits any authorized user of the community of users to have the capability of configuring and administrating electronic markets. A set of access permissions control which users of the community of users have access to electronic markets, and a set of usage permissions control the use of content contained in the electronic markets. A set of management permissions control which users of the community of users can manage the access and usage permissions for markets and content.

Abstract: Implementation of multi-user group nodes in a multimedia player provides multi-user communication of multimedia content in a client-server system is provided by dividing a client's scene into non-shared and shared parts. In a described embodiment, extensions are provided to a multimedia player that supports the MPEG-4 developing standard.

Abstract: A balun transformer having two series connected transformers with each having a primary loop conductor disposed in a stacked configuration. One portion of each primary loop conductors is in a first layer and these two portions of the two primary loop conductors are connected in series. The second portions of the primary loop conductors are in a second layer that is spaced from the first layer with the secondary loop conductors interlaced with these portions of the primary loop conductors in the second layer.

Abstract: A spray bottle which comprises a bottle body having a mouth around which an annular groove is formed and a spraying pump having a stem located through the mouth of the bottle body for pumping up and spraying out liquid contained in the bottle body. The spraying pump includes a press-knob incorporating a spraying nozzle provided at an upper end of the stem and a cap provided co-axially around the stem for locating the overall spraying pump in position upon fitting over the mouth. An O-ring is located in the annular groove for engagement with an inner side of the cap for sealing.

Abstract: A card carries a transparent blister for holding and displaying an article of merchandise, and the card may be reverse folded after purchase into a box which encloses the blister and the article and has an attractive outer surface printed with a gift wrap so as to eliminate the need for additional gift wrapping paper.
