20160033354 | METHOD AND DEVICE FOR LEAK DETECTION AND LOCATION FOR FLUID PIPELINES - The present invention discloses a method for leak detection and location for fluid pipelines, comprising a pipeline to be detected, characterized in that the pipeline to be detected is at least provided with two sensing devices having a certain distance therebetween. Acquisition points are formed at the positions of the sensing devices. The sensing devices can simultaneously sense acoustic vibrations of the pipeline in two directions, i.e., axial direction and radial direction of the pipeline, respectively. When there is a leak point in the pipeline to be detected between the two acquisition points, locating the leak point is performed according to the following formula: | 02-04-2016 |
20140262999 | REACTOR FOR SEWAGE TREATMENT - A reactor for sewage treatment including: an inner layer including a water distribution zone; a middle layer including a biological aerated filter, the biological aerated filer including a wall and a bottom including a water outlet; and an outer layer including an artificial wetland, the artificial wetland including a bottom including a water inlet. The water distribution zone, the biological aerated filter, and the artificial wetland are in the shape of a circle. The sewage is introduced into the water distribution zone via a water inlet pipe. The water distribution zone communicates with the biological aerated filter via a first overflow. The water outlet arranged on the bottom of the biological aerated filer is connected to the water inlet arranged on the bottom of the artificial wetland to allow the biological aerated filter to communicate with the artificial wetland. | 09-18-2014 |
20140144850 | SYSTEM AND METHOD FOR PURIFYING RAINFALL RUNOFF - A system for purifying rainfall runoff including a bar screen; a collection and diversion device; a filter channel; a grass ditch; and a water storage tank. The bar screen is disposed around the collection and diversion device for preliminarily filtering the road rainfall runoff. The collection and diversion device collects the road rainfall runoff and diverts early rainfall runoff to the filter channel, after the filter channel is full, later rainfall runoff is directly diverted to the grass ditch through open channels. The grass ditch includes a percolation bed capable of filtering the early and later rainfall runoff. The water storage tank is connected to the grass ditch via a guiding pipe, to receive the rainfall runoff effusing out of the grass ditch. Part of the rainfall runoff received by the water storage is transported to the percolation bed by a return conduit. | 05-29-2014 |
20140144835 | SYSTEM AND METHOD FOR HARVESTING RAINWATER - A system for harvesting rainwater for use in a skirt building. The skirt building includes a main building and a podium supporting the main building. The system includes: a standpipe; a buffer channel; a filter channel; and a green roof. The green roof includes a vegetation region including a baffled diversion corridor, and a bottom filtering layer including a drainage pipe. The standpipe is arranged on the main building and is connected to the buffer channel where the energy of rainwater flowing out of the standpipe is dissipated. The buffer channel, the filter channel, and the green roof are arranged on the podium, and the buffer channel communicates with the filter channel. The filter channel is connected to the green roof. The filter channel is divided into a plurality of sections respectively filled with different matrix materials. | 05-29-2014 |
20140124424 | INTEGRATED SYSTEM FOR TREATING AND RECYCLING RAINWATER - An integrated system for treating and recycling rainwater in a residential community. The residential community includes low-lying land. The integrated system includes a primary channel for receiving and treating initial rainwater, a baffled water treatment pool, and a reservoir. The primary channel includes an external wall and an inner wall. The baffled water treatment pool includes a water inlet which is disposed on the inner wall of the primary channel. The reservoir includes a water inlet, a gravel filter layer, and an overflow wall. The primary channel, the baffled water treatment pool, and the reservoir are disposed in the low-lying land. The primary channel is annular and surrounds the baffled water treatment pool and the reservoir. The overflow wall of the reservoir cuts off the annular primary channel. The baffled water treatment pool and the reservoir are adjacent to each other and are divided by a shared wall. | 05-08-2014 |
20120101387 | METHOD AND SYSTEM FOR NON-INVASIVE INTRACRANIAL PRESSURE MONITORING - Disclosed embodiments include a system and a method for determining intracranial pressure (ICP) of a subject that comprises: (a) applying transcranial Doppler (TCD) to determine the middle cerebral artery (MCA) velocity of the subject and estimating changes in the ICP continuously based on a functional mapping that relates arterial blood pressure (ABP) and cerebral blood flow velocity (CBFV) to ICP, resulting in an estimated ICP trend; (b) generating a flash visual evoked potential (FVEP) on the subject, processing a detected FVEP signal and obtaining an estimated ICP; and (c) combining the estimated ICP trend from TCD CBFV and ABP with the estimated ICP obtained by signal processing of the detected FVEP signal to periodically correct the trend and obtain a non-invasive measure of ICP. | 04-26-2012 |
