  • Publication number: 20140171011
    Abstract: A wearable emergency cellular device for use in a medical emergency alert situation includes an application containing synoptic medical information and other user data, a call module for mobile communication with a call center and a display for selectively controlling information displayed on the cellular device. Only the call center is able to input the synoptic medical and selected other information to the device. The cellular device is usable for emergency situations other than medical, such as for personal security at home or for mobile use. Various access methods are described using panel displays for medical or other emergency personnel to access the stored cellular device information. Initiation of user communication with the call center can be activated manually or by the user's voice. Also described are an electronic emergency call system and methods for handling an emergency alert using the emergency cellular device.

  • Publication number: 20140084870
    Abstract: A system for balancing charge within a battery pack with a plurality of cells connected in series, including a capacitor; a processor configured to select a combination of donor cells and receiver cells from the plurality of cells in one of the following two modes: (1) a first mode where the number of donor cells is equal to the number of receiver cells, and (2) a second mode where the number of donor cells is greater than the number of receiver cells; and a plurality of switches that electrically connect the capacitor to the donor cells to charge the capacitor, and that electrically connected the capacitor to the receiver cells to discharge the capacitor. The transfer of charge between cells in the plurality of cells through the capacitor balances the charge within the battery pack.

  • Publication number: 20140083870
    Abstract: A method is provided for determining analyte concentrations, for example glucose concentrations, that utilizes a dynamic determination of the appropriate time for making a glucose measurement, for example when a current versus time curve substantially conforms to a Cottrell decay, or when the current is established in a plateau region. Dynamic determination of the time to take the measurement allows each strip to operate in the shortest appropriate time frame, thereby avoiding using an average measurement time that may be longer than necessary for some strips and too short for others.

  • Publication number: 20130257381
    Abstract: A battery pack management system adjusts the relative state-of-charge of respective battery blocks in a battery pack to equalize (i.e., align, balance or otherwise make similar) the peak battery block voltages (i.e., maximum or “upper peak” battery block voltages when the battery pack is being charged and/or minimum or “lower peak” battery block voltages when the battery is being discharged). Upon detecting an anomalous battery block that exhibits outlier upper and lower peak voltages, the battery pack management system adjusts the relative state of charge of respective battery blocks to center their respective upper and lower peak voltages between operating limits, thus maximizing the operating margin of the battery pack as a whole.

  • Publication number: 20120274331
    Abstract: A method and apparatus for determining the state-of-charge of a battery. In response to detecting that the battery is in a rest state, a pre-conditioning current is drawn from the battery to affect a correlation between the state-of-charge of the battery and an open-circuit voltage of the battery. Thereafter, the open-circuit voltage of the battery is measured, and used to determine the state-of-charge.

  • Patent number: 8192610
    Abstract: Measurement of the series track resistance of a working and counter electrode pair in an electrochemical test strip provide error detection for multiple variations in the quality of the test strip, as well as the operation of strip in the test meter. In particular, a single measurement of series resistance can be used to detect and generate an error message when an incorrect reading is likely to result due to (1) damaged electrode tracks, (2) fouled electrode surfaces, (3) dirty strip contacts, or (4) short circuit between the electrodes.

  • Patent number: 8030942
    Abstract: An electrochemical cell has two terminals. One of the terminals is connected to a pulse-width-modulated (PWM) power supply and to a voltmeter. The other terminal is connected to circuitry capable of switching between amperometric and potentiometric measurement modes. A sequence of successive approximations permits selection of a PWM duty cycle giving rise to a desired voltage at the terminal connected with the power supply. In this way a stable excitation voltage is supplied to the cell even in the face of supply voltage instability or drift or instability in electronics coupled with the cell.
