Abstract

Multi-sensor system for real-time embedded monitoring of object senses mixed-mode object conditions. Various sensors separately provide disparate analog signals representing different measurable attributes regarding sensed object. For example, such sensors may separately sense temperature, pressure, or other biometric value. Then, according to specified rule set or other qualifying parameters, a digital signal is generated by a processor or controller to indicate one or more condition of the sensed object according to certain sensor input values. Additionally, such multi-sensor scheme may be coupled to a digital network or otherwise coupled thereto for simulation and/or communication applications.

Claims

1. Multi-sensor apparatus comprising:

a first sensor for generating a first signal for monitoring a first mode of an object, wherein the first sensor comprises a silicon-based microstructure having a cavity for sensing a cell condition; and

a second sensor for generating a second signal for monitoring a second mode of the object; and

an interface for processing the first and second signals to generate a third signal representing a sensed condition of the object indicated by the first and second signals, wherein the interface provides access by a network coupled thereto effectively to the sensed condition during a selected time segment or within a qualified sensor group according to a programmable instruction set which is executable by the interface.

2. In a multi-sensor system, a sensing method comprising the steps of:

receiving a first sensed signal for monitoring a first mode of an object, wherein the first sensed signal is provided by a silicon-based microstructure having a cavity for sensing a cell condition; and

receiving a second sensed signal for monitoring a second mode of the object; and

generating a third signal representing a condition indicated by the first and second sensed signals, wherein the sensed condition effectively is network-accessible during a selected time segment or within a qualified sensor group according to a programmable instruction set.
