Abstract:
The present disclosure relates to a vehicle radar system (3) comprising a signal generator (13) that generates a FMCW chirp signal (4) with a plurality of frequency ramps (r) running between a first frequency (f start) and a second frequency (f stop ). At the second frequency (f stop ), the signal generator (13) is controlled to output an output signal (4) with an output frequency (F out ) for initializing a further frequency ramp (r' ) using a frequency control signal (31) corresponding to a desired frequency (39) with an initial desired frequency part (39a) and at least one further desired frequency part (39b). The initial desired frequency part (39a) runs from the second frequency (f stop ) to an intermediate frequency (f i ) between the first and second frequency (f start , f stop ) ), and said further desired frequency part (39b) runs from the intermediate frequency (f i ) to the first frequency (f start ). The duration of the initial desired frequency part (39a) falls below the duration of said further desired frequency part (39b). The present disclosure also relates to a corresponding method.

The invention provides methods of attenuating, e.g., inhibiting or reducing, cellular proliferation and migration, particularly endothelial cell proliferation and migration, including that associated with angiogenesis, using opioid antagonists, including, but not limited to, those that are peripherally restricted antagonists.
Abstract:
An optical transmission system comprises an optical transmitter (1) for launching optical signals into an optical fibre, and drive means (4 to 9) for driving the optical transmitter independently with first and second electrical signals. The drive means is such that the optical transmitter (1) transmits first and second optical signals corresponding to the first and second electrical signals.
Abstract:
There is provided self-testing of a frequency-modulated continuous-wave, FMCW, radar device. A transmission signal comprising an object detection signal and a self-test signal superimposed on the object detection signal is transmitted. The self-test signal represents at least one virtual target. A reception signal is received. The reception signal is a received version of the transmission signal. Presence of the at least one virtual target in the reception signal is determined. A lack of presence of the virtual target in the reception signal provides an indication of hardware failure of the FMCW radar device.
Abstract:
Apparatus and a method for applying to and retrieving from a work to be protected covert identification consists of a predetermined identification (12) which is encrypted using a pseudorandom code (11). The encrypted identification is then added (14) as a noise-like feature to a signal of the work to be protected. The apparatus and method may be used to introduce covert identification into a music recording for example on a CD, literature or pictures and even into telecommunication signals. As the identification is implemented as a noise-like feature in the work, the identification cannot easily be extracted without knowledge of both the identification and the encryption code employed.
Abstract:
A system and method for mitigating interference in a frequency-modulated continuous-wave radar processing system is defined. Random inter-pulse jitter is implemented in a transmitted radar signal to prevent identification of false {racks due to interfering radar signals. Random intra-pulse jitter of time and/or frequency is implanted to create spreading of false targets and provide a method to distinguish false targets from true targets. Adjacent sensors in a multi-sensor radar" system are alternatingly configured to transmit either upward ramping or downward ramping frequencies to mitigate interference between adjacent sensors in the same radar system.
Abstract:
The present disclosure relates to a vehicle radar system (3) comprising at least one transceiver arrangement (7) arranged to generate, transmit and receive reflected radar signals. The transceiver arrangement (7) comprises an ADC arrangement (10) that is arranged to output a digital IF signal (20) in a time domain to a DSP arrangement (12). A first DSP function (12a) is arranged to: - identify and retain sample points of the digital IF signal (20) in a spectral domain with signal components that exceed a certain level threshold, such that an approximation signal (36) is formed in the time domain, - identify possible sections (37) of the digital IF signal (20) in the time domain that exhibit interference exceeding an interference threshold, - determine whether or not to replace such sections (37) with equivalent sections (38) of the approximation signal (36), and - if applicable, replace such sections (37) with equivalent sections (38) of the approximation signal (36).
Abstract:
The invention provides methods of attenuating, e.g., inhibiting or reducing, cellular proliferation and migration, particularly endothelial cell proliferation and migration, including that associated with angiogenesis, using opioid antagonists, including, but not limited to, those that are peripherally restricted antagonists, such as methylnaltrexone or alvimopan. The disorders to be treated alone or in combiantion with for instance - anticancer agents (5-f luorouracil or bevacizumab) are i.a. cancer, diabetes, sickle cell anemia, vascular wound, proliferative retinopathy.

Abstract:
Systems and methods are described for using methylnaltrexone in treating inhibition of gastrointestinal motility in equines. A method for preventing and treating opioid-induced and non-opioid-induced gastrointestinal dysfunction includes administering a quaternary derivative of noroxymorphone to an equine before or after the onset of the gastrointestinal dysfunction.
