On power-complementary FIR filters [PDF]
Conditions are derived, under which two linear-phase FIR filter transfer functions H(z) and G(z) have the power-complementary property, i.e., |H(e^{j \omega})|^{2} + |G(e^{j\omega})|^{2} = 1 . It is shown that, the constraint of linear phase on the transfer functions strongly restricts the class of frequency responses that can be realized by a power ...

Complementary filter synthesis of gyrostabilizer
This paper considers the synthesis of a complementary filter designed to determine the angular position of the gyrostabilizer platform. An engineering synthesis technique is proposed, allowing you to select filter parameters and evaluate its effectiveness. The question of the synthesis of a complementary filter in the platform is considered.

The orientation of a magneto-inertial measurement unit can be estimated using a sensor fusion algorithm (SFA). However, orientation accuracy is greatly affected by the choice of the SFA parameter values which represents one of the most critical steps.

Design of self-monitoring sensor for position and orientation of equipment in coal mine
Aiming at the problem that the performance of key equipment in underground coal mine is degraded and the function is lost to lead to a safety accident eventually due to the deviation of the installation position and orientation or the artificial movement

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

Application of Filters to Improve Flight Stability of Rotary Unmanned Aerial Objects
The most common filters used to determine the angular position of quadrotors are the Kalman filter and the complementary filter. The problem of angular position estimation consist is a result of the absence of direct data.
