Publication number: 20120285235Abstract: Mobile devices are re-supplied with fluids on a periodic basis thereby eliminating the need to maintain a permanent connection between an external fluid supply and the moving device. Electronic scanning devices generate heat and operate at varying and high temperature conditions that interfere with operations of the scanner heads. Circulating a heat transfer fluid through the sensor head removes excess heat from heat sensitive regions of the sensor head during operations. Once the heat transfer fluid reaches a predetermined temperature or after passage of a predetermined length of time, the scanner head is maneuvered to a docking station where it is coupled to an external heat fluid source where fresh fluid is supplied to the scanner head.Type: ApplicationFiled: May 14, 2011Publication date: November 15, 2012Applicant: Honeywell ASCa Inc.Inventor: Tadeusz Bik

Patent number: 8179676Abstract: Fluid-cooling technology developed for printed circuit boards (PCBs) and electronics assemblies is combined with optical-based interconnect technology, thereby enabling efficient fabrication of PCBs with free-space optical bearers. Since cooling components such as fans and heat sinks are no longer required on the PCB, the PCB is thinner and makes better use of a cooling substrate by also using it to carry optical signals. A card or a backplane supporting a plurality of active components can combine optical signals and cooling aspects in support of those components.Type: GrantFiled: July 21, 2010Date of Patent: May 15, 2012Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Martin Julien, Robert Brunner

Publication number: 20120085087Abstract: The invention relates to a method of regulating the temperature of a heat regenerator (ST1, ST2) used in an installation (10) for storing energy by adiabatic compression of air. The regenerator is subjected to successive operating cycles, each cycle comprising a compression stage followed by an expansion stage. Between two successive cycles, the method consists in cooling a bottom compartment (26a) of the layer of refractory material (26) of the regenerator that is situated in the proximity of the bottom distribution box (24) in order to bring the air leaving the heat regenerator to a temperature that is compatible with the range of temperatures required during the compression stages. The invention also provides such a heat regenerator.Type: ApplicationFiled: June 14, 2010Publication date: April 12, 2012Applicant: GDF SUEZInventors: Patrick Canal, Lionel Nadau
