摘要： A resonator is suitable for reducing or suppressing a force transmitted by a vibrating portion of the resonator to a support part. To this end, the vibrating portion includes two extensions which are each meander shaped such that two segments of each extension have respective speed components that are oriented in opposite directions. Such a resonator, which is balanced, can advantageously be used within a rate gyro or a force sensor.

摘要： Systems and methods for measuring web tension distribution in roll-to-roll processes, for example, such as R2R processes employed in the fabrication of printed devices. Such systems and methods entail a web that travels between first and second rollers in a longitudinal direction of the web, inducing tension in the web in the longitudinal direction thereof such that tension is present in a flexible substrate of the web between the first and second rollers, and operating the system to determine an average tension and linear variation of tension present in the flexible substrate resulting from the tension induced in the web inducing a nonuniform tension distribution in the flexible substrate between the first and second rollers. The systems and methods utilize one or more devices that induce deflection in the web between the first and second rollers.

摘要： The “Magneto Cyclist Power Sensor” is a device that computes “cyclist performance” values of pedal power, pedal force, cycle speed, and used gear position of a bicycle using the a aggregated signals from several vibration sensors that are a part of an assembly attached to the bicycle front derailleur. This device, working in conjunction with data from the internet and the cyclist Bluetooth or USB connected phone, is calibrated using known geographic topography of the riders location, prior information about the particulars of the bicycle (make, model and size) and past riding logs recorded by the device. The “cyclist performance values” can be used for providing the cyclist with a display of the computed values on their phone. The device attached to the front derailleur is composed of magnets, inductors, data acquisition and processing unit. Being attached to the derailleur, the device magnets and inductors move with the chain as the chain moves from gear to gear (also called sprocket).

摘要： This device is a sensor whose output can be used for providing the cyclist with a display of the power he/she is delivering to the wheels of the bicycle while he/she is riding. It can also be used to determine bike gear selection and bike ground speed. It is a sensor composed of magnet(s) and inductor(s) which attaches to a bikes front derailleur. Attaching the magnets and inductors to the derailleur causes them to move with the chain as the chain moves from gear to gear (also called sprocket) on the bike front gear assembly. Power is computed using a the vibrations of the bike and chain thats measured by the sensors and computed by a small signal processing chip.

摘要： The invention relates to an apparatus and method for extracting vibration data from a moving drive chain. In the preferred embodiment, the chain is that of a bicycle, or similar pedaled machine such as an indoor stationery bicycle, with two or more sensors placed on the chainstay of the bicycle to measure the vibrational frequency of the chain. Such vibration data can be used to determine the tension of the chain, and may also further compute the power transmitted by the chain, in conjunction with the measurement of chain speed. The invention provides a method and apparatus for conditioning and filtering the signals from the vibration sensors, as well as an arrangement for positioning the sensors on the bicycle.

摘要： A method of determining the tension in an elongated rod is described. The method includes impacting the rod and measuring the vibration response of the rod. Further, the method entails generating a theoretical vibration response of the rod based in part at least on the structural properties of the rod. Thereafter, the method entails adjusting the theoretical vibration response to cause the theoretical vibration response to conform with at least a portion of the measured vibration response. Based on the adjusted theoretical vibration response, the tension of the rod is determined.
