A method for the selective determination of the scattering index μ_s of a scattering biological matrix, in particular for the purpose of non-invasive determination of the concentration of glucose in the skin, by means of detection measurements, in each of which light in the form of primary light (9) is irradiated into the biological matrix (5) and an intensity measurement value of secondary light (12) exiting at a detection site (33-40) that is located at different measuring distances (ρ) from the respective light irradiation site (10) during the detection measurements is measured. In order to improve the quality and selectivity of the determination of μ_s, the primary light is irradiated obliquely at an angle between 5° and 85° using a contacting light-guiding element. In at least two detection measurements, the measuring distance (ρ) between the respective light irradiation site (10) and the respective detection site (33-40) corresponds to no more than five times the mean free path length of the light propagating in the biological matrix.

A system and method for determining and displaying a navigation route on a navigation device from one vehicle position to a travel destination. The navigation device can include processor with RAM, a mass storage device for holding a database with geographic data, as well as a display. Depending on whether a complex intersection is present on the navigation route, the complex intersection can be shown on the display in the form of a single perspective view. Embodiments of the invention can provide a high level of correlation between the actual situation on the road as seen by the user and the corresponding navigation maneuver displayed on the screen. The graphic output of navigation devices for complex intersections can also be improved regardless of whether the navigation device is a high-performance or very simple device.

A method increases the depth of focus of an eye having a line of sight. A pharmacologic agent is applied to the eye to cause a reduction in the size of the pupil of the eye. The pupil is aligned with a visible feature of a mask comprising a pin-hole aperture. The pin-hole aperture is centered on a mask axis. The alignment causes the mask axis to be substantially aligned with the line of sight of the eye. The mask is applied to the eye of the patient while maintaining the alignment of the visible feature of the mask and the pupil.

The present invention relates to a data transceiving method in a communication system based on a plurality of carriers, and more particularly, to a method of designing a sequence in a communication system using orthogonal subcarriers. The present invention includes the steps of generating a time-domain sequence with a specific length in a time domain, generating a frequency-domain sequence by performing a DFT or FFT operation on the time-domain sequence according to a length of the generated sequence, including a DC subcarrier and a guard subcarrier in the frequency-domain sequence, and performing an IDFT or IFFT operation on the frequency-domain sequence including the DC subcarrier and the guard subcarrier.

The microphone system of the invention executes an adaptive filter processing by using output signals from two microphones to output a speaker's voice signal with an improved SN ratio, in which the two microphones are laid out close to each other, and the angles formed by the orientations of the microphones with respect to the speaker's vocalizing direction are made different for each of the microphones. For example, the microphones are mounted on the sun visor of a vehicle, or on the ceiling above the front passenger seat or the driver's seat of the vehicle, with the orientations of the microphones differentiated. Further, the SN ratio of the output signal from one microphone is raised, and the SN ratio of the output signal from the other microphone is lowered. For example, one microphone is positioned right above a speaker's face, and the other microphone is spaced apart on the occipital side by about 1 to 5 cm from the position of the first microphone. Thus, the microphone system improves the SN ratio of the voice signal.

An automatic blood analysis and identification system permits patient identification and other vital information, such as blood type and Rh factor, to be automatically printed directly on a container holding a bodily fluid sample almost immediately after the sample has been drawn and analyzed. There is no manual handling of the sample between the draw and the identification. The system includes a carrier unit for holding at least one clear sample container, and a printer disposed within the unit for printing information onto the sample container. A photo-analyzer analyzes a bodily fluid sample within the sample container, and sends information to the printer which prints the information onto the sample container. The system may also be configured to utilize radio frequency identification (RFID) technology to imprint electronic data bearing the information onto a microchip implanted within the sample container.

A method for determining Covariance of Indicated Mean Effective Pressure (COVIMEP) using already-available crankshaft-based measurements that correlate with COVIMEP. Correlated values of COVIMEP are stored as lookup tables in an Engine Control Module for use in continuously determining COVIMEP during engine operation. COVIMEP thus calculated may be used in known fashion as a real time control algorithm variable for such engine control parameters as fueling rate, spark angle advance, exhaust gas recirculation flow, and camshaft phaser advance angle or other engine parameters.

Methods and systems are described for predicting the likely causes of service outages using only time information, and for predicting and the likely costs of service outages. The likely causes are found by defining a narrow likely cause window around an outage based on service quality and/or service usage data, and correlating service events to the likely cause window in the time domain to find a probability distribution for the events. The likely costs are found by measuring usage loss and duration for a given point during an outage and using cost component functions of the time and usage to extrapolate over the outage. These cause and cost predictions supply service administrators with tools for making more informed decisions about allocation of resources in preventing and correcting service outages.

An implantable cardiac monitoring device as an A-mode ultrasound probe which is adapted to be positioned in the right ventricle of a heart, and which emits an ultrasound signal which is reflected from one cardiac segment of the left ventricle of the heart, and the ultrasound probe receives the resulting echo signal. The delay between the emission of the ultrasound signal and the reception of the resulting echo is measured, and from this delay a position of the cardiac segment is determined. The position of this cardiac segment, at least one reflecting the signal, is related to cardiac performance, and thus the monitoring device determines, from the detected position of the cardiac segment, the cardiac performance.
