Patent CA-2950473-C (CA)
Inventor: WU TING-CHING
IPC: F03B13/14
Filed: 2016-12-02
Granted: 2018-10-23
Abstract: A negative-pressure wave generator (71) has multiple flow-driven assemblies (1) and a power-generating assembly (2) disposed in the sea. Each flow-driven assembly (1) has multiple Venturi tubes (13) connected to a power generating culvert (50) of the power-generating assembly (2). When sea water passes, the Venturi tubes (13) generate negative pressure to make the water flow into the flow-driven assembly (1) from the power generating culvert (50). A large pressure difference is formed between outside sea water and a chamber (511), and the pressure difference drives a turbine (72) to drive a generator assembly (70) of the power generating culvert (50). The transferring efficiency is high and the water in all the flow channels is in low pressure to prevent the water pipes (40) from burst and leakage. The negative-pressure wave generator (71) is simple in structure and solid, lowering the maintenance cost.

Title: Enhanced convection, differential temperature managed, hydronic heating appliance
Inventor: MERCIER PAUL D
IPC: F24D19/10
Filed: 2017-04-13
Granted: 2023-10-17
Abstract: A system, apparatus, and method for a differential temperature managed integral, free standing, hydronic heating appliance uses a high-mass heat source coupled to a single, highly-efficient, variable speed, Electronically Commutated Motor (ECM)-driven Delta-T stand-alone system circulator which feeds one or more zone valves governing flow to one or more hydronic zones. Components are integrated into simplified, compact, assemblies. Zone valve packaging of a compact header improves hydronic performance (head pressure reduction and increased flow), complementing zone valve performance and reducing zone valve wiring labor and material content. Returns have full port valves and the boiler includes isolation valves. All manually activated valves are full port. This can include full port boiler isolation valves, circulator isolation valves and return valves. Paralleled, ganged, alignment of state-indicating-lamped zone valves provides rapid, functional indication of component and system performance while the need for a zone valve panel commonly found on hydronic heating systems is negated.

Abstract: A boat loading guide system for use on a boat trailer, particularly for pontoon boats and the like. The boat loading guide is highly visible during loading, comprising two guide posts visible throughout the loading process. When not in use, or when towing the trailer, the guide posts are stowed such that the trailer and guide posts do not exceed a pre-determined width, and thus the trailer will be able to be operated legally on public roadways. The guide posts can be of sufficient length so that even when the rear portion of the trailer is well submerged, the guide posts will extend above the surface of the water and be visible to the operator.

Title: A stepwise refinement detection method for pavement cracks
Inventor: LI QINGQUAN
IPC: G06T7/00
Filed: 2015-04-27
Granted: 2022-12-13
Abstract: Disclosed is a stepwise-refinement pavement crack detection method. A processing on a pavement image comprises the following main steps: a road mark extraction and processing, an ROA extraction, an ROA-based adaptive segmentation by thresholds, an ROC extraction and an ROC directional feature weighting-based region growth. On the basis that a crack is a collection of pixel points having similar gray scales and has a significant spatial aggregation feature, the present invention can quickly extract an ROA, quickly position, via the ROA, a possible gray-scale section and a spatial position of a crack, adaptively segment an image by thresholds, establish a confidence evaluation criteria, and accurately extract an ROC. A crack growing direction estimation method based on segmental weighting can accurately estimate a growing trend of a crack. The present invention employs an improved region growth method, and a crack utilizes a confidence region as a seed region and grows with the growing trend of the seed region, thus fully ensuring an accuracy of crack growth and a completeness of crack detection.
