Patent CA-2531785-A1 (CA)
Inventor: FANFELLE ROBERT
IPC: H04L27/26
Filed: 2004-07-07
Abstract: A system for outputting a broadband signal outputs a number of input channel streams. The input channel streams first arrive at the system in a digital format. There the input channel streams are each directed to a modulator circuit. Each particular modulator circuit produces a digital upconverted signal for the associated channel streams. The outputs of the modulators are coupled to a summer circuit. Accordingly the summer circuit digitally sums the outputs of the modulator circuits. The summer circuit is coupled to a digital to analog converter (DAC). The DAC produces an analog signal from the digitally summed output of the summer circuit. The DAC is in turn coupled to an upconverter. The upconverter upconverts the analog output of the DAC into an output signal centered on a particular frequency.

Filed: 2005-03-17
Abstract: The present invention relates to compositions comprising polymers whose solubility characteristics can be changed by incubation and particularly ploy (hydroxyalkyl (meth) acrylamide mono/di-lactate) interpolymers. Another aspect of this invention is the application of such temperature sensitive polymers as release systems of biologically active compounds. The polymers of the present invention comprise monomers, which have modifiable functionality. The functionality of the monomers can for example be modified by the presence of hydrolysable groups. The modification is effected by the incubation, leading to a change of the water solubility characteristics of the polymer. The polymers used in the present invention contain hydrolysable chemical groups.  As a result the polymer's solution characteristics, specifically its lower critical solution temperature (LCST), change upon incubation.
