Abstract: Disclosed herein is a system for time aligning electric power system measurements at an intelligent electronic device (IED) using samples and sample time offset from merging units. The merging units do not require access to a common time signal. The IED does not require storage of a communication latency with the merging units. The sample time offset corresponds to a latency between obtaining the sample and receipt of the sample at the IED. The IED aligns samples from various merging units using sample time offset values communicated from the merging units to the IED. The IED performs monitoring and protection functions using the time aligned samples.

Abstract: A medical ventilator cart, for use in hospitals or other medical settings, stores and transports various components of a ventilator system, such as a Breath Delivery Unit, a display monitor, and a compressor. First and second platforms are suspended above a base of the cart and allow the various ventilator cart components to be separately and independently placed on and removed from the cart without the need to move or rearrange any of the other ventilator components. One version of the cart provides an additional compressor platform attached to the base for mounting a compressor below the first platform.

Abstract: This improved method of calibrating wood testing machines includes improved test bars, shim and software to direct the operator through the steps of calibration, storing interim results and calculating new calibration factors based on values read when the test bars are placed in the wood testing machine. This method avoids a number of problems in previous methods and apparatus. It properly corrects for changes in deflection in the measurement apparatus and changes in straightness of the test bars. The result is a more stable and reliable calibration that is referenced to precise measurement of the EI product for the test bar.
