| 20090049913 | METHOD OF BEAT TUNING IN A SLIGHTLY ASYMMETRIC RING-TYPE STRUCTURE - The present disclosure relates to a method of beat tuning in a slightly asymmetric ring-type structure, and can be effectively used to control the beat property of a structure such as a bell, which can be modeled to a slightly asymmetric ring. | 02-26-2009 |
| 20090165560 | DUAL MODE MEASUREMENT SYSTEM WITH QUARTZ CRYSTAL MICROBALANCE - A dual mode measurement system with quartz crystal microbalance (QCM) is provided, which includes a quartz sensing component, a first measurement circuit, a second measurement circuit and a switch unit. When the first measurement circuit is selected through the switch unit, the first measurement circuit and the quartz sensing component form an oscillation circuit and output a resonance signal. When the second measurement circuit is selected through the switch unit, the second measurement circuit outputs a frequency scanning signal to scan the quartz sensing component, so as to output an impedance sensing signal. | 07-02-2009 |

| 20100095774 | MASS MEASURING DEVICE AND CANTILEVER - Minute masses of a plurality of measuring objects are measured at a time. | 04-22-2010 |
| 20120144918 | LONGITUDINAL RESONATING MODE INERTIAL MASS SENSING SYSTEMS - The subject invention provides improved means to measure mass collected on a sample collection surface in real time. A resonant structure is used as the “scale” to determine the mass in real time. The invention employs a membrane, or collection substrate, on the end of a resonant structure resonating in the longitudinal direction. A structure resonating in the longitudinal mode offers a considerably higher resonant frequency than the same structure in the bending mode. The higher the resonant frequency, the more resolution in the frequency of oscillation is available to determine the mass of the collection surface or membrane. The present invention implements this attribute in connection with such a structure. | 06-14-2012 |
| 20140060191 | SENSOR FOR SENSING SUBSTANCES IN AN ENVIRONMENT - There is set forth herein a sensor for sensing of substances. The sensor can include a sensing crystal oscillator and a reference crystal oscillator. The sensing crystal oscillator and the reference crystal oscillator can be arranged in a phase locked loop so that the oscillators oscillate at a common frequency. The sensor can be configured so that there is a baseline phase differential between the oscillation frequencies of the sensing crystal oscillator and the reference crystal oscillator. Detectable substances accumulating on the sensing crystal oscillator will induce a phase shift between output frequencies of the reference oscillator and the sensing crystal oscillator to allow for highly sensitive sensing of substances in small concentrations. | 03-06-2014 |
| 20150068309 | SYSTEM FOR WEIGHING INDIVIDUAL MICRO- AND NANO- SIZED PARTICLES - A device for weighing micro- and nano-sized particles. The device includes a base portion, an oscillator coupled to the base portion and configured to vibrate the base portion, a first cantilevered beam coupled to the base portion, a second cantilevered beam coupled to the base portion, a first plurality of fingers coupled to the first cantilevered beam near the tip inwardly pointing toward the second cantilevered beam, and a second plurality of fingers coupled to the second cantilevered beam near the tip inwardly pointing toward the first cantilevered beam. | 03-12-2015 |
