Embodiments of the present invention relate to methods, devices, and systems to monitor activity. One method to monitor activity includes monitoring a sensor activated by an individual. The method also includes recording activation of the sensor, determining a behavior routine of the individual based on recorded activations of the sensor, and analyzing the recorded sensor activations to determine a behavior routine. The method also includes identifying a change in the behavior routine based on the analysis of the recorded sensor activations.

Embodiments of the present invention relate to methods, devices, and systems to monitor activity. One method to monitor activity includes monitoring activity of an individual including detecting a sensor activated by an individual during the individual's daily activities. The embodiment also includes comparing the sensor activation to a predetermined sensor activation timeframe, determining whether to initiate an alert based upon the comparison, and checking for at least one other sensor activation to confirm whether an alert should be initiated.

A pressure transmitter includes an isolator mounting assembly for isolating process fluid from an interior cavity of the pressure transmitter. The isolator mounting assembly includes an isolator plug for receiving the process fluid line pressure and coupling the line pressure to a sensor cavity formed by a header joined to a distal end of the plug. A ring member is attached to the header and the distal end of the plug to reinforce the joint formed between the isolator plug and the head. In another embodiment, the isolator mounting assembly includes a base and a support having first and second opposed ends. The first end is rigidly bonded to the pressure sensor while an epoxy joint joins the second end of the support to the base.

A two-wire transmitter senses differential pressure, absolute pressure, and process temperature of a process fluid. The information can be used to provide an output representative of mass flow through a pipe. The transmitter has an electronics module housing attached to a sensor module housing. The sensor module housing contains all the sensors for the pressures and includes a boss input for receiving a signal representative of a temperature or pressure signal. The three process variables are appropriately digitized, and received by an electronics circuit board in the electronics housing including a microprocessor for calculating the mass flow. The microprocessor in the electronics housing also calculates a compressibility factor and a discharge coefficients according to a polynomials of specific forms. The boss is integral to the sensor module housing and is adapted to fit either shielded twisted pair cabling or conduit.

Embodiments of the present disclosure relate to methods, devices, and systems for determining occupancy of a user. One method to determine occupancy of a user includes sensing a change in resistance of a sensor element of an occupancy sensor, correlating the change in resistance to a force transmitted to the occupancy sensor, and determining an occupancy status of a user based on the force transmitted.

A transmitter in a process control system for measuring flow rate measures total pressure (P.sub.TOT) and differential pressure (h) of process fluid flowing through a process pipe. The static pressure (P.sub.STAT) is determined based upon the total pressure (P.sub.TOT). The calculated static pressure is used to determine the fluid density (.rho.) and the gas expansion factor (Y.sub.1) of the process fluid flowing in the pipe. This information is used to calculate flow rate (Q) of the process fluid.
