摘要:
A passive coupling structure constructed using printed circuit board traces is used to separate the low and high frequency components of an incoming digital signal. The low and high frequency components of the signal are sent to separate receivers on an integrated circuit. The low frequency receiver may be a conventional level based receiver. The high frequency receiver is a Schmitt-trigger with hysteresis around a DC level or two comparators with separate reference voltages. The outputs of these receivers are combined to produce a receiver output that has increased reliability and noise immunity.

A printing device includes a developer for developing a latent image with toner particles; an imaging plate comprising a plurality of pixel plates; and a plurality of voltage generators connected respectively to the pixel plates. The voltage generators positively bias selected pixel plates to form a latent image that is developed with toner from the developer.Another printing device includes a developer for developing a latent image with toner particles; an imaging plate comprising a plurality of pixel plates for selectively receiving toner particles from the developer; a plurality of voltage generators for biasing respective to pixel plates; and a background grid in the imaging plate for preventing toner particles from being deposited in areas between the pixel plates, wherein the background grid is connected to a voltage generator for applying a range of biases, positive and negative to the background grid. A method of electrophotographic printing in which toner particles are moved electrostatically from a developer to develop a latent image includes positively biasing selected pixel plates of a plurality of pixel plates of an imaging plate to form the latent image; and developing the latent image with the toner particles from the developer.

A connector assembly configured to be mounted to a device substrate is provided. She connector assembly includes a connector substrate, an electronic component. contacts, and conductive wires. The connector substrate has a mounting side and an opposite supporting side interconnected by an edge. The mounting side is used to mount the connector substrate to the device substrate. The electronic component is disposed on the supporting side of the connector substrate. The contacts are provided on the mounting side of the connector substrate and are used to electrically couple the electronic component with the device substrate. The wires are joined to the electronic component and to the contacts. The wires extend along the supporting and mounting sides and wrap around the edge of the connector substrate. The conductive wires are separated from one another by a separation gap along the supporting side and the mounting side of the connector substrate.

An electrical connector includes a housing having a plug cavity configured to receive a modular plug therein. A terminal assembly is coupled to the housing. The terminal assembly has a plurality of terminals configured to engage corresponding terminals of the modular plug. The electronic connector includes a magnetic assembly that has a circuit board. The terminals are terminated to the circuit board. The magnetic assembly has magnetic circuits coupled to the circuit board. Each magnetic circuit has a ferrous portion and conductors circumferentially wrapped around the ferrous portion. At least one of the magnetic circuits is coated with a coating material that includes a matrix and filler. The filler can have a higher or lower dielectric constant than the matrix. The dielectric characteristics of the nano-composite can be tuned by varying the concentrations of the filler and matrix material. This tunable nano-composite can serve as an additional design knob for better impedance matching for the magnetic connectors over a wide frequency range.
