  • Patent number: 11976999
    Abstract: The present disclosure relates to chain monitoring systems and methods. In particular, the chain monitoring system is configured to mount onto a portion of a chain and measure one or more parameters associated with one or more characteristics of the chain. The measured parameters are processed by the chain monitoring system and/or transmitted to a remote system for analysis. The analysis may be used to determine a characteristic and/or change in the characteristic of the chain. In some examples, the characteristic is an elongation value associated with the chain, which can be transmitted to a networked system for analysis, display, and/or control. In some examples, a sensor can be employed to measure one or more characteristics of the chain. The sensor may include, but is not limited to, a strain gauge, an accelerometer, an optical, a sonic, and/or a magnetic sensor.

  • Patent number: 11970845
    Abstract: A water flow valve positioned within a waterline preferably just past a building's water meter. The valve compresses air bubbles into the water at the point where the water enters the meter, thus improving the accuracy of the meter reading. The internal passageway of the valve is non-linear and causing the water traveling therethrough to go through a plurality of turns. A blocking disk and spring are used to close off communication between a first portion of the internal passageway and a second portion of the passageway in a valve closed position. With enough water flow pressure the spring is compressed which causes the blocking disk to retract and allow water to travel through the passageway, while creating the backpressure in the waterline to collapse the air bubbles prior to the bubbles being read by the water meter. A laminar flow for the water can also be created which can reduce the wear and tear on the water meter possibly extending the useful life for the water meter.

  • Patent number: 11933771
    Abstract: A first liquid sending controller of an analysis control device controls a first liquid sender such that a mobile phase is supplied to a fluorescence detector through an analysis column and a junction during an analysis of a sample. A sample introduction controller controls a sample introducer such that the sample is introduced into a mobile phase by the sample introducer at a position farther upstream than the analysis column during the analysis of the sample. The second liquid sending controller causes a second liquid sender to start supplying a fluorescent reaction liquid such that the fluorescent reaction liquid arrives at the junction later than a point in time at which supply of the mobile phase starts and before the sample introduced into the mobile phase arrives at the junction during the analysis of the sample. A generator generates a chromatogram based on an output signal of the fluorescence detector during the analysis of the sample.

  • Patent number: 11885641
    Abstract: An elastically supported electrode substrate for detecting unbalanced mass of a resonant gyroscope includes an outer frame and an inner structure. A connection part configured to be connected to an anchor of a resonator is arranged at the center of the inner structure, and electrodes are distributed on the inner structure. The inner structure is connected inside the outer frame through elastic beams, and the inner structure has torsional and/or translational resonant modes inside the outer frame. The resonant frequency of the inner structure approaches resonant frequency of an operating mode of the resonator. Since the resonant frequency of the elastically supported electrode substrate approaches the resonant frequency of the operating mode of the resonator, the vibration displacement induced by the unbalanced mass of the elastically supported electrode substrate can be significantly magnified to improve the detection sensitivity.

  • Patent number: 11874179
    Abstract: There is disclosed a handheld air flow velocity measurement probe that includes a bridge circuit assembly having an airflow velocity sensor that is a resistance temperature detector (RTD) and a digitally controlled resistive element to dynamically adjust and maintain the resistance of the velocity sensor within the overheat temperature predefined range. The velocity measurement also uses a separate temperature sensor to sense the temperature of the air or gas flow. A humidity sensor is also included remote from the other sensors to measure humidity in the gas flow to be measured. All of the above described components are housed at a probe tip instead of a base as in most standard handheld probes and the digital interface at the probe tip allows the user to replace a bulky, expensive telescoping antenna with stackable extender scheme.
