DETAILED DESCRIPTION OF THE INVENTION
20 The signal conduction matrix is a structure that is partially or substantially made of at least one type of light-transmissive material formed into a shape that would allow the transmission of a signal within the signal conduction matrix--using at least one surface signal 25 router. The signal conduction matrix is described in more detail below, but one of its characteristics is that it can be used as a substrate, such as an optical substrate, that can be formed into various shapes such as a rectangular slab or the shape of a part or the entirety 30 of, for example, a main frame of an instrument panel 3654p4vl 14 October 2002
- 8 - display. The signal conduction matrix can also be integrated as a substrate or part of the substrate of, for example, a printed circuit board. As such, it can be used as a primary or secondary transmission means for a signal, 5 such as an optical signal propagating from at least one signal source to at least one signal receiver.
The signal conduction matrix and signal transmission method of the invention provides several advantages. It 10 eliminates or minimizes the need for wiring and connectors on the substrate and eliminates the need for shielding which is normally necessary to block electromagnetic interferences involving light signals. The present invention is also highly reliable, easier to assemble, and 15 has a higher efficiency of coupling between transmitter/receiver and the signal conduction matrix.
Another advantage of the present invention is that optical signals can be transferred within the matrix multi-
directionally, i.e., a single master transmitter can talk 20 to multiple slave receivers simultaneously and a single receiver can listen to multiple transmitters. In addition, the signal conduction matrix of the invention can be integrated as a substrate or part of the substrate of, for example, a printed circuit board, or as part of a 25 molded threedimensional structure. Further, because the present invention eliminates cross-talking and interference between adjacent signal conductors, noise and signal distortion are excluded or reduced.
3654p4vl 14 October 2002
- 9 In one aspect of the invention, electronic, optical, or optoelectronic components are placed on the surface of the signal conduction matrix. In another aspect, the signal conduction matrix encompasses one or more electronic, 5 optical, or optoelectronic components to allow a signal such as an optical signal to be directed to the various components within the substrate. Thus, one or more components may be embedded within the signal conduction matrix while other components are positioned on the lo surface of the signal conduction matrix. Signal transmission can therefore be accomplished without having to resort to the use of conventional connectors, wirings, or signal focusing means such as a beam splitter or focusing lens. The signal conduction matrix may also 15 assume other shapes such as a ring, strand, sheet, or ribbon. Structures that comprise a matrix include a matrix in the form of strands or other structural shapes. Structures 20 that comprise a matrix also include a matrix connected: or fabricated with one or more components or systems such as a detector, light source, or an electronic system.
A surface signal router directs a signal from the signal 25 source to one or more target signal recipients, such as a photodetector or an IR analyzer, that are positioned at various points on the surface of the signal conduction matrix. A surface signal router can be a reflective coating on the surface of the signal conduction matrix.
30 When reflective coatings are used as surface signal 3654p4vl 14 October 2002
- 10 routers, they are preferably strategically distributed throughout the various areas or sections of the surface of the signal conduction matrix depending on factors such as the number and type of components that form part of a 5 signal conduction network.
A surface signal router can also assume the form of an indentation or a pressure fit structure. It can also assume the form of inclined, oblique, or wedge-shaped cuts 10 on the surface of the 3-D signal conduction matrix. As used herein, an "inclined') cut includes cuts having an angular shape relative to a surface of the matrix; this includes oblique and wedge-shaped cuts. Routers in the form of- surface cuts with other shapes such as zig-zag, 15 wavy, or combinations of various shapes may also be used.
Preferably, these surface cuts are coated with at. least one reflective material such as a metal or metal alloy.
In one aspect, a combination of reflective coatings and surface cuts with reflective coatings is used to enable a 20 signal to propagate through the signal conduction matrix via, for example, multiple internal reflections.
Examples of the various possible configurations of a system incorporating the signal conduction matrix of the 25 invention are provided in, for example, Figs. 1-3 to illustrate how multiple signals, which are represented by light beams of different wavelengths, undergo multiple internal reflections and propagate towards their target destination. The present invention can be incorporated as 30 part of an electronic system such as an integrated 3654p4vl 14 October 2002
- 11 powertrain control system (IPCS). For light transfer over short distances, a molded matrix translucent or transparent to the signal frequencies can be used. On the opposite side of the substrate, a layer of reflective 5 material can be deposited. The reflective material directs the light or RF signal into the matrix for subsequent collection by a target signal recipient.
The surface signal routers can be applied or incorporated 10 onto the surface of the signal conduction matrix so a signal can be transferred directionally to their receivers; As Fig. 3 shows, the signal emitted from one source on a substrate surface can be received by several signal receivers through the aid of surface signal 15 routers.
For a given substrate volume, the signals reflected by various surface signal routers can be combined into a total internal reflection signal. The total internal 20 reflection signal can then be directed to another portion or section of the matrix where another component such as a receiver may receive and/or process the collected internally reflected signal.
25 When different frequencies are used, multiple signals can be transmitted simultaneously. One signal source can have several corresponding receivers. To eliminate possible interference between signals having different frequencies, frequency-specific filters, such as bandpass filters, can 30 be used to selectively allow a signal with a particular 3654p4vl 14 October 2 002
- 12 frequency or frequency range to be picked up by an intended receiver. The signals can also be amplified during signal propagation so the signal can propagate over longer distances.

The signal conduction matrix 100 comprises signal sources 102, 104, a signal conduction 10 matrix 106, and signal receivers or collectors 108, 110, 112. The signal sources 102, 104 and receivers 108, llO, 112 are linked by connectors 114 to other components (not shown) in the electronic component system. The connectors 114 may be wires, optical connectors, other conveyance 15 devices, or a combination of these connectors.

25 As used herein, "operatively connected" refers to the formation of an optical, electrical, or other interface for transmitting and receiving the signals through the signal conduction matrix 106. The phrase "operatively connected" also means being connected, attached, or bonded 30 to a surface using attachment configurations, attachment 3654p4vl 14 October 2002

Each receiver 108, 110, 112 receives or collects one or more signals from the signal 5 conduction matrix 106. Preferably, each receiver 108, 110, 112 provides an output signal to the electronic component system in response to the signal. Each receiver 108, 110, 112 may have a frequency specific filter to reduce or eliminate interference from signals with 10 different frequencies. The frequency specific filter allows a particular signal receiver to selectively receive a signal having one particular frequency. The receivers 108, 110, 112 may be positioned essentially anywhere on the surface of the signal conduction matrix 106 to receive 15 the one or more signals. Multiple signal receivers may receive the signal from a single signal source.
In yet another aspect of the invention, a signal source and a receiver may be integrated into a single component 20 such as an RF transceiver, which may transmit a first signal at a given time and receive a second signal at another time. The first and second signals may have different frequencies.
25 Each signal may essentially diffuse throughout the entire volume of the signal conduction matrix 106. As used herein, "essentially diffuses" refers to the propagation of a signal in substantially all directions within the signal conduction matrix 106 unless, for example, a 30 component blocks the signal.
