Abstract: A cable distribution system includes a head end connected to a plurality of customer devices through a transmission network that includes a remote fiber node that converts digital data to analog data suitable for the plurality of customer devices, where the head end includes at least one server each of which includes a respective processor.

Abstract: A cable distribution system includes a head end connected to a plurality of customer devices through a transmission network that includes a first remote physical device, where the first remote physical device includes remote physical layer processing, that converts digital data to analog data suitable for the plurality of customer devices, where the head end includes at least one server each of which includes a respective processor.

Abstract: The invention herein describes a novel photobioreactor (PBR) system for culturing algae. The PBR system utilizes vertical transparent tubes that can be cyclically filled with an algae culture. The vertical tubes further feature pipe pigs deployed therein to disrupt formation of biofilm on the inner walls during the cyclic filling and emptying of the cultures.

Abstract: A system and method for automatically blending gases, comprising an input device for receiving predetermined mixed gas concentration data from the user, a plurality of gas inlet valves which allow a plurality of gas flows to enter a homogenizing chamber for mixing the plurality of gas flows into a mixed gas, at least one gas sensor for detecting the concentration of one or more components of the mixed gas and generating at least one output signal representative thereof; and a manager for receiving the at least one output signal and comparing the at least one output signal with the predetermined mixed gas concentration data and in response generating a signal to at least one gas inlet valve to modify the plurality of gas flows to maintain the desired mixed gas concentration.
