A method for manufacturing a planar electronic device includes applying a non-conductive fluid polymer to a lower side of a planar substrate. The substrate includes a hole extending through the substrate. The method also includes curing the fluid polymer to form a solid centering layer on the lower side of the substrate, with the centering layer extending across the hole along the lower side of the substrate. The method further includes loading a ferrite material body into the hole of the substrate through the upper side of the substrate, embedding the ferrite material body in an encapsulating material in the hole, and forming one or more conductive loops around the ferrite material body. The ferrite material body is held within the substrate between the lower side and the upper side of the substrate by the encapsulating material.

A planar inductor device includes a ferrite body and a conductive pathway, The ferrite body extends around an opening in the ferrite body. The conductive pathway includes an input section, a current-splitting section, a coil section, a current-combining section, and an output section connected with each other, the input section extending toward the opening in the ferrite body. The current-splitting section includes a plurality of conductive coils joined with the conductive pathway and electrically disposed parallel to each other. The coil section includes the conductive coils helically wrapped around the ferrite body. The current-combining section includes the conductive coils joined with each other. The output section includes the joined conductive coils extending out of the ferrite body.

The current invention provides an integrated planar transformer and electronic component that includes at least one wideband planar transformer disposed in a planar substrate, where each wideband planar transformer includes a planar substrate in a fully-cured and rigid state, a ferrite material embedded in the planar substrate, where the ferrite material is enveloped in an elastic and non-conductive material, inter-wound conductors disposed around the embedded ferrite material, where top and bottom conductors are bonded by an insulating adhesive. The top and bottom conductors are connected in an inter-connected pattern by conductive vias disposed on each side of the ferrite material and span through the layers to the conductors. The planar transformer further includes at least one center tap connected to at least one inter-wound conductor. The integrated planar transformer and electronic component further includes at least one electronic component connected to at least one terminal of the wide-band planar transformer.

A network repeater having automatic speed switching capability. The repeater includes a first repeater logic for connecting devices operating at the first rate to a first backplane, a second repeater logic for connecting devices operating at the second rate to a second backplane, and a port switching fabric, coupled to the first and second repeater logic, for determining the transmission rate of a signal at a port and routing the signal to one of the repeater logic according to the transmission rate determination. The repeater includes a serial controller for accessing internal management counters, LEDs for providing status information about the repeater and a media access controller for controlling functions including the transmission loopback and reception of Ethernet frames.

Automatic speed switching repeater

A system operable with any number of different display truth table schemes. The system allows a user to select the truth table scheme and a driver circuit is used to drive either a single or pair of display elements. A binary application select detects a logic 0 if an application sense pin is left floating or is pulled low with a resistor. It detects a logic 1 if the application sense pin is pulled high with a resistor. The sense potential is such that all applications at the pin following reset, namely input or output with connected components will only detect a logic 1 when the pin is pulled high by a pull-up resistor. The output latched application is directed to a responsive circuit operable in a first condition when a logic 0 is detected, and a second condition when a logic 1 is detected. A binary select allows 2,different truth schemes to be selected where n is the number of pins used to select the application. When a first binary code is sensed, a first truth table is implemented. When a second binary code is existent, a second truth table is implemented and so on. The driver, sensor and responsive circuit are formed as an integrated circuit device.
