Method and apparatus for illumination and communication
InactiveUS20060239689A1Electroluminescent light sourcesSemiconductor lamp usageCarrier signalData signal
The present invention provides a method and apparatus of using light-emitting elements for illumination as well as communication of data, wherein potential flicker due to sub-fusion frequency data correlations can be reduced compared to prior art techniques, while reducing redundancy in the data transmission. The intensity of the illumination from the light-emitting elements is controlled by a dimming signal such as a pulse width modulation (PWM) signal or a pulse code modulation (PCM) signal, for example. An amplitude-modulated data signal is then superimposed on the dimming signal for communication of data. The dimming signal thus acts as a carrier signal for the data signal. A sensing means is then used to receive the data signal by detecting all or part of the illumination from the light-emitting elements. The data signal can subsequently be extracted from the detected illumination.

Selected system calls are monitored to generate frequency data that is input to a probabilistic intrusion detection analyzer which generates a likelihood score indicative of whether the system calls being monitored were produced by a computer system whose security has been compromised. A first Bayesian network is trained on data from a compromised system and a second Bayesian network is trained on data from a normal system. The probabilistic intrusion detection analyzer considers likelihood data from both Bayesian networks to generate the intrusion detection measure.

Feature vector of appearance frequency of pedestrians, i.e., objective variables of estimation, is expressed by 12th dimension vector space. Moreover, status information is used as explaining variables, which explain the feature vectors when a feature vector occurs. The regression relationship of the feature vector with respect to the status information vector expressed in 28th dimension is solved by the linear least squares method.

Distributed frequency data collection via DNS

Domain Name Service (DNS) requests are used as the reporting vehicle for ensuring that security-related information can be transferred from a network. As one possibility, a central facility for a security provider may maintain a data collection capability that is based upon receiving the DNS requests containing the information being reported. In an email application, if a data block is embedded within or attached to an email message, an algorithm is applied to the data block to generate an indicator that is specifically related to the contents of the data block. As one possibility, the algorithm may generate a hash that provides a “digital fingerprint” having a reasonable likelihood that the hash is unique to the data block. By embedding the hash within a DNS request, the request becomes a report that the data block has been accessed.

Several techniques are disclosed for isolating either heart or breath rate data from a photoplethysmograph, which is a time domain signal such as from a pulse oximeter. The techniques involve the use of filtering in the frequency domain, after a Fast Fourier Transform (FFT) has been conducted on a given photoplethysmograph also references as a given set of discrete time-domain data. The filtering may be applied to an identified fundamental frequency and one or more harmonics for heart related parameters. The filter may be truncated to the frequency data set and further applied multiple times to improve roll off. After filtering, an Inverse FFT (IFFT) is used to reconstruct the time-domain signal, except with undesirable frequency content eliminated or reduced. Calculation or measurement of parameters is then conducted on this reconstructed time-domain signal.

In a configuration according to a short-range radar of the present invention and a method of controlling the same, the timing at which a variable-period pulse output from a variable-period pulse generator including a direct digital synthesizer (DDS) has shifted in level first since reception of a search instruction is used as a reference timing, so that a signal that shifts in level at the reference timing or a fixed lapse of time later than the reference timing is generated and output as a transmission trigger signal, and a signal that shifts in level at a timing delayed by half a period of the variable-period pulse or its integral multiple from the timing at which the transmission trigger signal is output is generated and output as a reception trigger signal. With this, by varying beforehand frequency data of the DDS based on the relationship between the frequency data and delay time between transmission and reception stored in a memory, it is possible to vary delay time between the transmission trigger signal and the reception trigger signal. It is thus possible to arbitrarily vary the delay time between transmission and reception at a high time resolution by using a simple configuration and low power dissipation.

Frequency synthesizer using a VCO having a controllable operating point, and calibration and tuning thereof
InactiveUS6888413B1Electric signal transmission systemsResonant circuit tuningLoop filterOperating point
A frequency synthesizer, a calibrator thereof, and an operating controller thereof are described. The synthesizer comprises a main charge pump that drives a voltage controlled oscillator (VCO) through a loop filter. The calibrator includes a second, replica charge pump that can also drive the VCO, but is set up to output only its maximum or minimum analog output control voltage. Since the construction and characteristics of the replica charge pump duplicate the main charge pump, the main charge pump's minimum and maximum analog control outputs can be cloned out to the VCO on demand. A VCO calibration procedure therefore includes switching the VCO to each of its ranges set by a bank of fixed capacitors, and using the replica charge pump to drive the VCO to its minimum and maximum frequency for each range setting. The min-max frequency data is stored in a lookup table, and operational requests to switch to a new channel frequency can be supported with a priori information about which fixed-capacitor range selection will be best. The operating point controller includes a sensor to sense the operating point and a controller that provides a switching input to a switchable bank of capacitors to change the operating point. The change can be determined according to calibration data.
