A computer-representable object (including, without limitation, a cryptographic key, or a graph or a Boolean description of a system) is secured using a generalized camouflaging technique. The secured object need not be stored in the system, not even in encrypted form. Instead, the technique employs a composition function that regenerates the secured object when one inputs a valid password (which may be any computer-representable information held by a user). By regenerating the secured object each time a valid password is entered, there is no need to store the secured object. If one inputs an invalid password, the technique may generate an incorrect object, such that the user is unable to distinguish this incorrect object from the secured object. If the user tries to use the incorrect object, the user can be exposed as unauthorized, without the user's knowledge that he has been exposed.

In a drawdown strategy for an investor's retirement fund, assets from the fund are allocated between a drawdown account and an option annuity. The drawdown account contains assets that are invested in the markets, and the option annuity contains annuities that begin to pay at the end of a deferral period. In a first phase of investor's retirement, funds are drawn down from the drawdown account and paid to the investor, and the value of the option annuity grows as proceeds from the option annuity are accumulated by the option annuity. At some point the drawdown account is depleted, which corresponds to the end of the deferral period for the option annuity. At this time, a second phase of the retirement begins wherein the investor receives payments from the option annuity, and this continues for the remainder of the investor's life.

In audio processing for an audio or video conference, a terminal receives audio packets having transform coefficients for reconstructing an audio signal that has undergone transform coding. When receiving the packets, the terminal determines whether there are any missing packets and interpolates transform coefficients from the preceding and following good frames. To interpolate the missing coefficients, the terminal weights first coefficients from the preceding good frame with a first weighting, weights second coefficients from the following good frame with a second weighting, and sums these weighted coefficients together for insertion into the missing packets. The weightings can be based on the audio frequency and/or the number of missing packets involved. From this interpolation, the terminal produces an output audio signal by inverse transforming the coefficients.

The present disclosure provides advantageous systems and methods for significantly increasing the sensitivity and selectivity for diagnostic procedures, e.g., optical biopsy. The disclosed systems and methods use a highly non-linear effect, the so-called photon avalanche. In the regime close to the avalanche threshold, small differences in density of the probe-ion under investigation or the excitation power can result in very large changes in up-conversion emission intensity. Through this effect, it becomes possible to accurately measure the signal of an optical biopsy probe-ion only in the location(s) where its concentration is highest, while at the same time significantly reducing or eliminating measurement of background signal from probe-ions distributed with a somewhat lower concentration throughout the measurement volume. Also background auto-fluorescence of the surrounding healthy tissue is essentially absent with this technique.

A controller in a receiver monitors RSSI and AGC gain levels to determine signal conditions and adjust filter performance accordingly to optimize power consumption while providing acceptable signal quality. When RSSI level is high and AGC gain is low, a strong signal-of-interest is present. In this case, adaptive filter bias currents may be reduced raise the noise floor and degrade intermodulation to reduce power consumption because the strong signal-of-interest can tolerate the higher noise and distortion. When the RSSI level is low and AGC gain is high, a weak signal is present a low noise mode may be effected by increasing bias current to filters used to lower the noise floor, but intermodulation effects may still be tolerated so those filters may be cut back. Other cases are supported. RSSI and AGC gain level thresholds may be dynamically altered based on relative RSSI and AGC levels.

The invention concerns a chaotic communications system, method and apparatus having a transmitter configured to spread an input data signal over a wide intermediate frequency band, by digitally generating a first chaotic sequence of values to form a spreading code. The spreading code is then used to form a digital IF chaotic spread spectrum signal having a uniform sampling interval. The duration of the sampling interval is then selectively varied in accordance with a first pseudo-random sequence, thereby introducing a known dither in the digital IF chaotic spread spectrum signal. After introducing the known dither, the digital IF chaotic spread spectrum signal is converted to an analog RF spread spectrum signal at a conversion rate that exceeds the sampling interval of the chaotic spread spectrum signal. A corresponding receiver recovers the input data from the spread transmitted signal. This spreading may utilize a chaotic sequence employing discrete time chaos dithering.

An improvement in the security of a logic system by minimizing observable features such as the power supply or electromagnetic radiation, so called, “side-channel attacks”. Specifically, the present invention comprises a technique and methods for reducing the ability of an intruder to monitor the relationship between currents in the system and the data in the system through the use of a randomized clock wherein the clock eye diagram is closed and without significant reduction in maximum operating speed compared to the reduction in maximum operating frequency that occurs when using conventional means of additive jitter. A system where the clock eye diagram is completely closed is provably more secure than systems where the clock eye diagram is partially open.

A detection circuit for detecting changes in capacitance. The detection circuit includes a tuned ratio circuit and an alternating current (AC) source AC-coupled to the tuned ratio circuit. The tuned ratio circuit includes first and second tuned circuits that are tuned to, or close, to the frequency of the AC source. Output circuitry is coupled between the two tuned circuits. During use as a transducer, an active capacitive transducer is inductively coupled to the first tuned circuit. Changes in the capacitance of the active capacitive transducer cause changes in the tuning of the first tuned circuit. The output circuitry generates an output signal that is a function of the difference between the tunings of the first and second tuned circuits.

A technique in which a false detection and a wrong diagnosis can be suppressed in a capacitance sensor represented by an acceleration sensor is provided. A first capacitative element and a second capacitative element, which configure a capacitance detection unit, and a third capacitative element and a fourth capacitative element, which configure a forced oscillation generation unit, are electrically separated from each other. That is, the diagnosis movable electrode that configures the third capacitative element and the fourth capacitative element is formed integrally with the movable part. On the other hand, the diagnosis fixed electrode and the diagnosis fixed electrode are electrically separated from the detection fixed electrode and the detection fixed electrode.
