Abstract: Images of vehicles traveling on a road are sensed by a plurality of monitor cameras arranged along the road. Video signals obtained by these monitor cameras are A/D-converted into digital images. These digital images are so corrected that the road shown in each digital image runs in the longitudinal or lateral direction of the image. The corrected digital images are composited such that the roads shown in these images continue. This allows the whole of the road as an object of traffic monitoring to be displayed on a single screen. Since the entire road can be monitored without switching images to be displayed, the speed of traffic abnormality detection increases. <IMAGE>

IPC: H03M7/00
Filed: 1987-08-29
Granted: 1998-09-10
Abstract: A digital coding process for transmitting and/or storing acoustic signals, in particular musical signals, in which N pick-up values of the acoustic signal are transformed into M spectral coefficients. The process is characterised by the fact that in a first stage the M spectral coefficients are quantified. After coding, an optimal coder checks the number of bits necessary for reproduction. If the number of bits is above a predetermined number, the quantification and coding are repeated in further stages until the number of bits necessary for reproduction no longer exceeds the predetermined number of bits. The required quantification stage is transmitted or stored in addition to the data bits. The advantage of the process is that acoustic signals in particular musical signals, can be transmitted and/or recorded without any subjective quality reduction of the musical signals with a reduction of data rate by factors of 4 to 6.

The calibration chamber (4) contains a calibration fluid (5)-e.g. a dry gas-while second chamber (10) contains a second fluid (11)-e.g. a wetting agent. Immediately prior to a calibration process the lid (8) is removed, whereafter a sensor with its measuring surface in front is inserted through the second chamber (10) into the housing (2) until it abuts against a shoulder (6) in the housing (2). This causes the barrier layer (3) to rupture and the second fluid (11) to contact the calibration fluid (5). Hereafter the calibration process can take place. In another embodiment the device (1) further comprises a membrane (12) which is accommodated in the second chamber (10) and is adapted to be secured to the sensor during the insertion of the sensor into the housing (2). The disclosed device-which is particularly suited for use in calibrating sensors for transcutaneous registering of the contents of CO2 and/or O2 in blood-is self-contained, and can be made in a very compact design, making it very well suited for use in connection with portable equipment. The device is also suitable for being manufactured in the form of a disposable unit.

Abstract: A magnetoelastic torque sensor for providing an output signal indicative of the torque applied to a member about an axially extending axis of the member, comprising, a first magnetoelastically active region in the member, the region being magnetically polarized in a single circumferential direction and possessing sufficient magnetic anisotropy to return the magnetization in the region, following the application of torque to the member, to the single circumferential direction when the applied torque is reduced to zero, whereby the magnetoelastically active region produces a magnetic field varying with the torque. Magnetic field sensors are mounted proximate to the magnetoelastically active region and oriented with respect thereto to sense the magnitude of the magnetic filed at the sensors and provide the output signal in response thereto. At least the magnetoelastically active region of the member is formed of a polycrystalline material wherein at least 50 % of the distribution of local magnetizations lie within a 90°C quadrant symmetrically disposed around the single circular direction and having a coercivity sufficiently high that the field arising from the magnetoelastically active region does not magnetize regions of the member proximate to the magnetoelastically active region to give rise to parasitic magnetic fields which are of sufficient strength to destroy the usefulness, for torque sensing purposes, of the net magnetic field seen by the magnetic field sensor means.
