Publication number: 20230022527Abstract: A subsea sensor module includes a sensor housing having a first section, a second section and a third section, each section having an outer profile and a module flange having an inner profile. An outer surface of the flange is substantially perpendicular to an outer surface of the housing in the first section. The housing outer profile and flange inner profile are substantially the same along the second section of the housing. A shoulder is formed in the housing outer profile in the third section by a transition of the diameter of the outer profile from a smaller to a larger diameter. The flange has a corresponding shoulder in the flange inner profile; wherein the flange is shrink fit mounted radially outwardly of the sensor housing second section such that the shoulders are in contact.Type: ApplicationFiled: January 5, 2021Publication date: January 26, 2023Applicant: Siemens Energy ASInventors: Hans Knutsson, Andrew Robert Eastoe, Kjetil Haldorsen

Patent number: 10721083Abstract: Power is supplied to telecom equipment in DSLAM outdoor/remote cabinets with relatively short distances between the subscriber and the cabinet. All of the subscriber Customer Premises Equipment connected to the DSLAM each provide a portion of the required power to the remote cabinet via the telephone line connecting the DSLAM and the subscriber CPE. The CPE at the subscriber premises is already connected to power mains in the subscriber premises so, providing power, via the telephone line to the outdoor cabinet is relatively simple. The remote cabinet includes a circuit for receiving the power input from each subscriber and then distributing the power, required by the DSLAM load, equally among the subscribers.Type: GrantFiled: February 1, 2019Date of Patent: July 21, 2020Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Jan Hansen, Hans Knutsson
