| 20120119791 | DIGITALIZED SENSOR SYSTEM - A digitalized sensor system includes a portable electronic device, a sensor unit, a transmission unit and a signal converting unit. The portable electronic device has a first connection portion. The sensor unit is configured for measuring and/or monitoring physical and/or chemical parameters of a target object to generate a digital signal. The transmission unit includes a connecting wire and a second connection portion, the connecting wire adapted to be connected with the sensor unit and the second connection portion, the second connection portion adapted to connect to the first connection portion, and the second connection portion and the first connection portion forming a pluggable interface. The signal converting unit is configured on the transmission unit and adapted for converting the digital signal into a second signal, the second signal adapted to be transmitted to the portable electronic device by the transmission unit. | 05-17-2012 |
| 20110201383 | SENSOR APPARATUS AND SENSOR SYSTEM USING THE SAME - A sensor apparatus includes a portable electronic device and a sensor unit. The portable electronic device includes a signal processing unit, a transmitting unit, a receiving unit and an outputting unit. The sensor unit is adapted to electrically connecting with the portable electronic device by a USB interface. The sensor unit is adapted for sensing a physical and/or chemical parameter of a target object and generating a digital signal. The signal processing unit is capable of receiving the digital signal via the USB interface and then transmitting the digital signal to the transmitting unit. The transmitting unit transmits the digital signal to a server. The server processes the digital signal for obtaining a result. The receiving unit is capable of receiving the result from the server. The outputting unit is electrically connected with the receiving unit and adapted to output the result. | 08-18-2011 |
| 20110031119 | PLASTIC POTENTIOMETRIC ION-SELECTIVE SENSOR AND FABRICATION THEREOF - The present invention discloses a plastic potentiometric ion-selective sensor based on field-effect transistors which can be fabricated to form the miniaturized component via sputtering and/or printing method. A plastic potentiometric ion-selective sensor doesn't need an additional bias voltage to convert the signals. The disclosed plastic sensor comprises a plastic substrate, at least one working electrode formed on the plastic substrate, a reference electrode printed on the substrate, and a golden finger printed on the plastic substrate. The golden finger is for electrically coupling with the external world and for outward transmission of signals detected at the working electrode and the reference electrode. The disclosed plastic potentiometric ion-selective sensor is replaceable. | 02-10-2011 |
| 20100051457 | PLANAR INTEGRATED ION SENSOR - A planar integrated ion sensor has a planar substrate, a working electrode assembly, a reference electrode assembly and an exchange junction. The working electrode assembly is mounted on one surface of the planar substrate and has an ion selective electrode, a working conductor electrically coupled with the ion selective electrode and a working barrier partially covering the ion selective electrode and the working conductor. The reference electrode assembly has a reference electrode, a reference conductor electrically coupled with the reference electrode, a reference barrier partially covering the reference electrode and the reference conductor and a hood with an inner space filled with electrolyte. The exchange junction allows communication between a liquid sample and the electrolyte in the inner space of the hood. The present invention has a decreased volume, is easily portable and is convenient for an operator to determine ion concentration in the liquid sample without incorporating other device. | 03-04-2010 |
