Abstract: A paging system with a remote pager (15) which includes a transmitter (18) with a plurality of individually selectable encoded acknowledge signals (29-32). The system includes apparatus (11) at the paging terminal (12) for composing messages with a primary message and a plurality of alternate responses, each response corresponding to one of the acknowledge signals. Upon reception of the page, the pager (15) is operated by selecting the acknowledge signal (29-32) corresponding with the desired response to the primary message. Transmission of the selected acknowledge signal (29-32) acknowledges reception of the page and, simultaneously, partially answers the primary message.

Abstract: Apart from the desired radial oscillations, rod-shaped resonators also emit undesired longitudinal oscillations. In order to avoid this undesired emission of longitudinal oscillations, and to achieve a higher emitted power of the sound-emitting part, it is proposed to couple a further sound transducer of the same type to the end of this sound-emitting part that was previously free.

Abstract: The field of the invention is that of correction devices applicable to a digital signal, at the transmission or at the reception end, for compensating for distortions introduced by the transmission channel, in particular on pairs of twisted wires, of the type usable in private links with variable characteristics and high disturbance factor. The aim of the present invention is to provide means permitting automatic choice of a level of equalisation matched to the cable's transfer function, for the current transmission. The device is characterised in that it comprises means (103, 105, 115) of detecting code violations at the reception end, cooperating with means of adjusting the means of correcting (521, 522, 523, 524; 113, 117) the transmission distortions. <IMAGE>

Abstract: The present invention is a method and apparatus for determing the distance of a surface patch of an object from a camera system and also for focusing a surface patch of such object as well as obtaining an improved focus image of the surface patch. The present invention also includes a method of determining a set of unknown parameters of a linear shift-invariant system. The camera system of the present invention has an aperture through which light enters, an image detector, an image forming optical system having first and second principal planes and a focal length, the second principal plane arranged closer to the image detector than the first principal plane, a light filter a camera controller, and an image processor operatively connected to the image detector and to the camera controller. The camera is set to a first set of camera parameters which include the distance (s) between the second principal plane and the image detector, the diameter (@) of the camera aperture, the focal length ( NLG ) of the camera system and the spectral characteristic ( lambda ) of light transmitted by the light filter. The first image is recorded on the image detector and is preprocessed as a digital signal to provide a first normalized image related to the point spread function of the camera system by a convolution operation. A first set of Fourier coefficients are calculated at a set of discrete spatial frequencies. Then at least one of the camera parameters is changed and a second image is formed on the image detector and is processed as the first image was processed. The first set of Fourier coefficients are divided by the second set of Fourier coefficients to provide a set of ratio values. A single mathematical relationship corresponding to each member of the set of ratios is provided without the necessity of an intermediate parameter and without regard to the form of the point spread function of the camera system. The relationship represents the ratio of the optical transfer function of the first normalized image to the optical transfer function of the second normalized image. The mathematical relationship depends only on the camera parameters and has one unknown, which is equal to the distance of the surface patch from the camera system. The ratio value can be substituted in a single mathematical relationship to obtain a set of equations which can be solved to determine the distance of the surface patch from the camera system. Alternatively, the set of ratio values can be compared to the values in a look-up table stored in computer memory. The location in the table where the stored values match the ratio values gives the distance of the object from the camera system. The apparatus and the method of the present invention are widely applicable and they significantly enhance the efficiency of image processing to provide the distance of an object and required changes in the camera parameters to focus the object.
