A monitoring system for monitoring an environment and generating data in response to the presence of at least one chemical hazardous to human health in the environment. The monitoring system is configured to communicate the data to an associated personal communication device or the like for processing. The monitoring system can be in the form a selectively attachable component.

A battery management system configured to detect impending failure of a lithium-ion battery cell includes a sensor array microchip. The microchip includes a plurality of silicon chemical-sensitive field effect transistors (CS-FETs) configured to detect multiple distinct gases vented by the lithium-ion battery cell. The battery management system also includes a cell monitoring unit (CMU) configured to receive from at least one of the CS-FETs data indicative of a detected amount of gas vented by the lithium-ion battery cell. The CMU is also configured to compare the data indicative of the detected amount of the vented gas to a predetermined threshold amount of the subject vented gas programmed into the CMU. The CMU is further configured to trigger a signal indicative of impending failure of the lithium-ion battery cell when the detected amount of the vented gas exceeds the predetermined threshold amount of the subject vented gas.

A site monitoring system is provided including a base unit configured to be mounted to a structure of a monitored site; at least one sensor configured to monitor at least one monitored site condition; and a controller disposed within the base unit, the controller configured to receive sensor information regarding the at least one monitored site condition from the at least one sensor and to receive operation information from at least one monitored site management system. The controller is configured to process the sensor information and the operation information against predetermined monitored site parameters and to provide control instructions to the at least one monitored site management system to affect the at least one monitored site condition.

A wireless tracking system comprises a plurality of tape nodes associated with entities in an environment. The entities may comprise, for example, users, machinery, ingress and egress points of the environment. The tape nodes are configured to detect interactions that occur within the environment. Interactions may be defined based on one or more conditions, such as threshold durations or proximities between tape nodes. Interactions are stored by the tape nodes, uploaded to the wireless tracking system, and may be retrieved at a later time responsive to an event occurring, such as suspected contamination or incorrect use of machinery.
