Techniques are disclosed which provide a substantially constant battery reserve capacity with respect to therapeutic medical devices. Accordingly, a battery control system may be operable to maintain a substantially constant reserve capacity throughout the life of the battery. The battery reserve capacity activation threshold may be set and continuously or periodically updated so that a battery's remaining capacity equals the predetermined reserve capacity when the measured parameter reaches the activation threshold, thereby allowing a maximum amount of a battery's total capacity to be employed for therapeutic use and reserve only that portion of that capacity determined to provide for a desired level and / or period of device function after reaching the reserve threshold.

The present invention describes a method and apparatus for measuring the voltage and current characteristics of the OLED pixel as it ages and correlating the measured data to the decrease in quantum efficiency and changes in OLED impedance over the life of the OLED, so that corrections can be made to the image drive system to prevent image sticking and color point drift. The method and apparatus of the present invention do not require any additional circuitry or changes in the display design. The circuitry of the present invention is implemented in the display driver integrated circuit (IC) chips. The basis of the invention is the luminance-current-voltage (LIV) curves which characterize the OLED materials over their life time. A series of these curves are stored in memory representing a OLED material at various ages. The apparatus of the present invention is used to measure driver voltages and currents for a pixel having an OLED, which measurements are then used to extract the voltage current curve for the OLED at any point in time. The extracted curve is compared to the aging curves stored in memory to determine the aging curve that best describes the measured present voltage current characteristic of the pixel. That aging curve is used to drive the pixel.

The present invention provides for a system for operating a communication device (20) for reception of scheduled intermittent information messages (22) with a dual mode timer (70) that extends battery life. A controller (50) schedules the timer (70) to power down all idle components of the device (20) between message receptions in a power saving sleep mode to conserve battery power. During active mode when the device is fully active in reception of messages, the timer (70) uses a reference oscillator (90) with a relatively high frequency to support digital processing by the receiver (26). During sleep mode when only the timer is powered on, a much lower frequency sleep oscillator (96) is used to maintain the lowest possible level of power consumption within the timer itself. The timer (70) has provision for automatic temperature calibration to compensate for timing inaccuracies inherent to the low-power low-frequency crystal oscillator (96) used for the sleep mode. The resultant improvement in timer accuracy during sleep mode eliminates the need for an initial reacquisition period following wake up in active mode, thereby reducing battery drain in active mode as well.

An energy-efficient consumer device audio power output stage provides improved battery life and reduced power dissipation. A power supply having a selectable operating mode supplies the power supply rails to the power amplified output stage. The operating mode is controlled in conformity with the audio signal level, which may be determined from a volume control setting of the device and / or from a signal level detector that determines the amplitude of the signal being amplified. The power supply may be a charge pump in which the operating mode uses a capacitive divider to provide for selection of a power supply output voltage that is a rational fraction of the power supply output voltage in a full-voltage operating mode.

The present invention is directed to a miniaturized apparatus to locate, track, recognize and control objects using miniature RF circuits that are programmed as an active tag or as one of several embodiments of a controller, including one small enough to be incorporated into a personal object, like a ring. In its simplest embodiment, a portable or wearable controller communicates wirelessly with a tag secured to a surface, analogously to a car remote—push button, receive a signal from tag or back at the controller, to locate tagged object. In more complex forms, the tag can be integrated into objects or connected to a network. One controller can manage a plurality of tags. The basic platform of tag and controller can be built up to create a sophisticated area control with environmental sensors, inventory functions, tracking individuals and allowing or denying access, operating objects like doors and lights, and creating supporting ambient security with checks and balances between tags and controllers on people and their possessions, such as baggage at an airport. Arrays of tag or controllers extend the wireless range to accommodate large structures and areas. This novel system is self-contained, with a low power protocol to give long battery life time and does not require internet or GPS to perform its functions.

The invention also tracks the time required for the battery charge to deplete. Charge duration decreases over time, and whenever it reaches a predetermined minimum, the battery monitoring equipment transmits a representative status message to the remote site.

A framework for adaptively managing the life of components. A sensor provides non-destructive test data obtained from inspecting a component. The inspection data may be filtered using reference signatures and by subtracting a baseline. The filtered inspection data and other inspection data for the component is analyzed to locate flaws and estimate the current condition of the component. The current condition may then be used to predict the component's condition at a future time or to predict a future time at which the component's condition will have deteriorated to a certain level. A current condition may be input to a precomputed database to look up the future condition or time. The future condition or time is described by a probability distribution which may be used to assess the risk of component failure. The assessed risk may be used to determine whether the part should continue in service, be replaced or repaired. A hyperlattice database is used with a rapid searching method to estimate at least one material condition and one usage parameter, such as stress level for the component. The hyperlattice is also used to rapidly predict future condition, associated uncertainty and risk of failure.
