Multi-modal fluid condition sensor platform and system therefor
First Claim
1. An integrated system for continuous monitoring of multiple properties of a fluid derived from measurements from one or more sensors within a fluid-based closed-system environment comprising:
- a bolt comprising one or more embedded sensors for continuous monitoring of properties of a fluid including pressure, temperature, or fluid level or a combination thereof, and an aperture at an end of the bolt allows the one or more sensors to contact said fluid; and
one or more non-sensor elements comprising a wireless transmitter.

Abstract
This invention encompasses embodiments for multi-modal integrated simultaneous measurement of various aspects of fluids contained in circulating systems such as automotive reciprocating engines and vehicle transmissions. These circulating systems perform constant internal lubrication, and heat and contaminant removal to protect the internal moving parts from the inherent friction and damage in normal operation. Most commonly this is achieved with fluids based on hydrocarbon and/or related synthetics, which, over time, can lose their protective properties, and vary in their performance or breakdown/decay due to internal and external events. Several components within the lubricant fluid can be measured and can provide insight into the efficacy of the system to perform its designed mission. Described herein is a real-time, simultaneous, integrated, multi-modal sensor system for early warning notification.
