摘要： An apparatus to determine body sleeping posture includes a sensor sheet (figure 2) having a plurality of pressure or vibration sensors (221, figure 2) arranged in rows and columns substantially parallel and perpendicular to the longitudinal direction of a person lying on a bed (50, figure 4). In one embodiment posture information is displayed along with other physiological information (e.g. respiratory measurements) detected by either the senor sheet or another sensor. In other embodiments both sleeping posture and position (e.g. supine, prone, sideways) is determined from senor sheet measurements of pressure or vibration.

摘要： The frequency-modulated CW radar employs a transmitter (12) and two receivers (14,16) delivering beat signals (B1,B2) to an analyser (20) where they are digitised (24a,24b) for phase computation, differencing and comparison (26). The computer also produces the activation signal (C1) of the triangular-wave generator (22) driving the modulator (12a) of the voltage-controlled oscillator (12b). The phase differences between the reception channels are determined during the rise and fall of the transmission frequency. Their sign gives the relationship between the transmitted and received signals, and hence the sign to be attributed to each peak frequency determined as an absolute value of the frequency difference.

摘要： A visual ability improvement device installed in a vehicle includes a noise generator, a surrounding situation detector, a driver status detector, a vehicle status detector, an operation switch, and a noise output device. A controller of the noise generator determines an optimum strength based on the surrounding situation from the surrounding situation detector, the driver's status from the driver status detector, the vehicle's status from the vehicle status detector, and the correspondence of the optimum representative noise to the above situation and statuses from the correspondence memory. Then the controller generates a noise with the determined the optimum representative noise strength, and outputs to the noise output device such as passenger compartment light a control signal which depends on the generated noise.

摘要： A living body information display apparatus, together with a sleeping posture and position detection apparatus, is used to correctly and suitably capture an abnormal condition in a living body while the living body is sleeping/lying on a bed or on the apparatus. Living body information and sleeping posture/position are captured by pressure sensors placed under a sleeper. The living body information includes, for example, respiratory information, body movement information, and sleeping posture. The information of the sleeper is represented in color-coded time chart, in writing and in a rough image based on the sensor signals. By using this apparatus, a user can readily understands the position, posture and respiratory information of the sleeper.

摘要： An FM-CW radar which is suitable for automotive anti-collision systems, for example, is provided. This radar outputs a radar signal in the form of a triangular wave whose frequency is increased at a given rate and decreased at a given rate. A receiver receives a wave reflected from a target to produce a beat signal and takes the Fourier transform of the beat signal to determine peak frequency components thereof showing peaks in a frequency spectrum. The receiver also determines phases of the peak frequency components and selects at least one from the peak frequency components in a frequency-rising range wherein the frequency of the radar signal is increased and at least one from the peak frequency components in a frequency-falling range wherein the frequency of the radar signal is decreased which show substantially the same phase to pair them for determining the distance to and relative speed of the target based on the frequency of the paired peak frequency components.

摘要： PROBLEM TO BE SOLVED: To detect distances and relative velocities among all targets even when a plurality of targets to be detected exist. SOLUTION: With an FMCW radar device having two reception channels CH1 and CH2, beat signal consisting of mixed transmission signal and reception signal is Fourier-transformed at every reception channel of CH1 of CH2 and at rising part wherein the frequency of the transmission signal increases and falling part wherein the frequency decreases and all peak frequency components whereat each power spectrum forms a peak, are detected. Then, phase differences Δϕu(i), Δϕd(i) of the peak frequency components of the same frequency between the reception channels CH1 and CH2 are calculated (310, 320) for every rising part and falling part. When peak frequency components properly selected one by one from the rising part and the falling part and the absolute value of the difference in the phase difference, |Δϕu(i)-Δϕd(i)| is smaller than a specific value ε, these peak frequency components are identified as a pair (330, 340).

摘要： PROBLEM TO BE SOLVED: To provide the opening surface antenna which can detect the azimuth of a target with high precision. SOLUTION: This antenna is equipped with a dielectric lens 4 which converges a radar wave arriving from outside and a reception part 6 consisting of three primary radiators which receive the radar wave converged by the dielectric lens 4. The reception part 6 is arranged shifting from the focus F to the dielectric lens 4 by a specific distance Dx along the antenna axis Xa connecting the center and focus F of the dielectric lens 4, and the three primary radiators which constitute the reception part 6 are arranged along an array axis Xb crossing the antenna axis Xa at right angles. Thus, the primary radiators are arranged off the focus F, so receive signals having a sufficiently large phase difference corresponding to the azimuth θ where the radar wave arrives are obtained from the respective primary radiators, so the azimuth can precisely be detected.
