  • Patent number: 8928328
    Abstract: A testing device for solid oxide fuel cell (SOFC) is disclosed. The testing device which combines the original cell housing with a four-point probe equipment is set for measuring SOFC MEA. The current collectors on anode and cathode in the original cell housing are respectively replaced by four independent probe units. They are not only to collect current but also to become measuring probes. Therefore, the lateral impedance of anode and cathode can be measured. Furthermore, the local characteristics are examined by open circuit voltage (OCV), I-V curve, and electrochemical impedance spectroscopy (EIS) measurements. The results show that the lateral impedance is substantially varied with temperatures. The distributions of OCV, current density, EIS and cell voltage in long-term test at the center of the cell are different from the edge.

  • Patent number: 8664960
    Abstract: When a battery current is not larger than a limit current set depending on the battery temperature and is flowing continuously for a predetermined time set depending on the battery temperature or longer, a decision is made that a secondary battery is in stable state. When the secondary battery is in stabilized state, the battery voltage is considered to be equal to the open circuit voltage and SOC estimation is performed based on the open circuit voltage-SOC characteristics. When the product of the internal resistance of the secondary battery and the limit current is made substantially constant (constant voltage) by setting the limit current in association with temperature dependence of the internal resistance, estimation error can be kept within a predetermined range in the stabilized state even if SOC estimation is performed while the battery voltage is assumed as the open circuit voltage.

  • Patent number: 8330467
    Abstract: A measuring device is used in conjunction with a programmable controller for monitoring electrolyte levels in the battery. According to one implementation, the measuring device is located in a battery and is configured to detect when the electrolyte level in the battery falls below a particular level. The controller is in electrical communication with the electrolyte detection device. The controller is configured to: (i) receive a signal from the electrolyte level detection device indicating when the electrolyte level in the battery has fallen below the particular level; (ii) introduce a wait-period after the signal is received; and (iii) enable an indicator to indicate that the electrolyte level in the battery should be refilled when the wait-period expires.

  • Patent number: 8299902
    Abstract: Systems, products, and methods are disclosed for helping to ensure that an alarm of a mobile communications device is activated when desired. An illustrative method includes receiving an indication of a desired time that the alarm is intended to be activated, determining a power level of a power source that is powering the mobile communications device, determining whether the power level will provide sufficient power to the mobile communications device to enable it to activate the alarm at the desired time and, if so, then enabling the alarm to be set. Further, the power source could be monitored as the alarm-activation time approaches so that if variables change that might prevent the alarm from activating, then changes or preventive measures can be taken.

  • Patent number: 8274291
    Abstract: When a battery current is not larger than a limit current set depending on the battery temperature and is flowing continuously for a predetermined time set depending on the battery temperature or longer, a decision is made that a secondary battery is in stable state. When the secondary battery is in stabilized state, the battery voltage is considered to be equal to the open circuit voltage and SOC estimation is performed based on the open circuit voltage-SOC characteristics. When the product of the internal resistance of the secondary battery and the limit current is made substantially constant (constant voltage) by setting the limit current in association with temperature dependence of the internal resistance, estimation error can be kept within a predetermined range in the stabilized state even if SOC estimation is performed while the battery voltage is assumed as the open circuit voltage.

  • Patent number: 8248087
    Abstract: A liquid concentration measuring device has first and second switches, which are turned on and off at two frequencies. When the first switch is turned on and the second switch is turned off, a detection electrode pair is charged. When the first switch is turned off and the second switch is turned on, the positive side of the detection electrode pair is grounded so that the charged detection electrode pair discharges. The difference between the output voltages of an amplifier produced by charging and discharging the detection electrode pair at the two frequencies is used to determine an alcohol concentration in gasoline.

  • Patent number: 8196218
    Abstract: An exemplary, highly integrated, SPM-based system for measuring the conductivity and/or force of substance under programmable engaging/stretching processes is described. A sample bias is applied across two electrodes. A substance to be measured is sandwiched between them. A first electrode is first brought relative to a second electrode (engaging) in programmable pathways that can be described as stretching distance versus time curves. The process of engaging the electrodes continues until a certain current reached, a certain force reached and whichever case happens first. The electrodes are then separated (stretching) in programmable pathways that can be described as stretching distance versus time curves. A periodic modulation can be applied to the engaging/stretching process to realize different stretch pathways. The sample bias across the electrodes is kept constant or swept in a programmable shape over time, described as a voltage-versus time curve.
