Abstract: The invention relates to video surveillance systems that are used, for example, for surveying public places, stations, streets, industrial estates, buildings or similar. Said video surveillance systems comprise one or more surveillance cameras that are oriented towards surveillance scenes and transfer image data streams, in the form of image sequences, to an evaluation centre. The invention also relates to a device (1) for identifying and/or classifying a movement pattern in an image sequence of a surveillance scene comprising a plurality of moving objects, an interface (2) for recording the image sequence, a calculation module (5) for determining an optical flow field (10) in the surveillance scene by evaluating the image sequence and an identification module (6) that is designed in terms of programming and/or circuitry such that the optical field and/or partial areas thereof are compared to one or more patterns in order to identify the movement pattern in the image sequence.

Abstract: An inventory module for a video monitoring system including at least one monitoring camera which is directed or directable to a monitoring region, in particular a storage and/or sales area which contains products, including a detection device which is designed to detect products, and when detection takes place, position information and information regarding the identification of detected product are ascertained, includes an assignment device which is designed to model—based on the position information and the identification information of a plurality of detected products—a spacial distribution of the products in the monitoring region.

Abstract: An image processing device for the detection and suppression of shadows in a camera image of a surveilled scene, the camera image optionally showing static objects with static shadow regions and moving objects with dynamic shadow regions, includes a long-term module, which is designed to generate a long-term reference image of the surveilled scene by evaluating a long-term observation of a particular scene, a mid-term module, which is designed to generate a mid-term reference image of the surveilled scene by evaluating a mid-term observation of the particular scene, and a shadow detection module, which is designed to process camera image—using information technology—with long-term reference image and mid-term reference image, in order to detect and suppress shadows.

Abstract: A wireless communication unit (300) incorporates a receiver comprising radio frequency circuitry (210, 220, 230, 240) for receiving a radio frequency signal and converting the radio frequency signal to a low frequency signal. A signal level adjustment circuit receives the low frequency signal and an analogue to digital converter (370), operably coupled to the signal level adjustment circuit receives an adjusted low frequency signal and providing a digital received signal. A signal processor (108) operably coupled to the analogue to digital converter (370) processes the digital received signal. The signal level adjustment circuit includes a low frequency amplifier (360) whose gain is arranged to be dependent upon a clip point of the analogue to digital converter (370).

Abstract: In a communications receiver (100) with a front stage (110) for receiving a transmitted RF input signal and a mixer stage (130) for mixing the RF input signal with an oscillator signal (OS) to provide an intermediate frequency (IF) signal, wherein the front stage (110) and the mixer stage (130) are coupled by an interconnecting section (130), intermodulation (IM) effects are reduced by (a) creating a forward (F) current through the section (120) by forward current means (R1, R3, R5, R4, C3, C1, C3, PD1, switch 140), (b) creating a reverse (R) current through the section (120) by reverse current means, (c) selectively coupling forward (F) and reverse (R) current means to the section (120) by selector means (140), to reduce the amplitude of the signal (RF OUT), which is applied to the mixer stage (130), and (d) operating the mixer stage in its linear operating range.

Abstract: The present invention relates to a diagnostic method for the diagnosis of Pestivirus infection in animals, in particular to a method for the diagnosis of animals infected with BVDV. A monoclonal antibody directed to a conserved antigen determinant on the Pestivirus ERNS protein is provided which allows the identification of infected animals with a high sensitivity and specificity.

Abstract: A radio communication device (100) such as a mobile telephone comprises signal converters (110, 130, 140), a band-pass filter unit (120) and an oscillator (150). In the receiving mode (I) a first converter (110) converts an HF signal into an intermediate ZF signal (20) which, upon filtering by the band-pass filter unit (120), is converted into an NF signal by means of a second converter (130). In the transmission mode (II), the device (100) employs the first converter (110) and the filter (120) for compression of the dynamic range of a microphone signal (40). The first converter (110) converts the microphone signal (40) into a further intermediate ZF signal (50) which is subjected to amplitude limitation by means of a limiter circuit (121) in the filter unit (120) and filtered by means of a filter (122). The third converter (140) converts the filtered and limited signal (51, 52) again into a low-frequency signal (60).
