Abstract: Described herein are thermal mass flow sensors that combine calorimetric and anemometric (e.g., hot-wire) elements to provide a hybrid approach to determining flow rate of a liquid. The flow probes or flow sensors are configured to use a heater to apply heat to a thermally-conducting material in contact with the flowing liquid, to measure a temperature of the thermally-conducting material upstream of the heater and downstream or at the heater, to adjust power to the heater to achieve a targeted temperature difference, and to determine a flow rate based at least in part on the power supplied to the heater and the measured temperatures. This approach provides flow rate due at least in part to the fluid cooling the thermally-conductive material proportionate to flow rate with non-linear effects. This hybrid approach can provide accurate readings of flow rates of liquids delivered through an IV line to a patient.

Abstract: A business recovery system includes an array of modular work stations, a central communications center, modular cables, and a trellis structure for establishing a data and power link between the work stations and communications center. The trellis structure is used for channelling cables from the communications center overhead to conduits, or pods, located at each group. The pods are fastened to walls of cubicles housing the work stations. A series of modular jacks on the conduit are used to connect localized data and power links to each work station, thus providing a direct data and power link between the work stations and the communications center.
