Abstract: An inflatable watercraft includes an upper wall, a lower wall connected to the upper wall so as to form a bottom main body, an inner wall extended longitudinally, and an outer wall also extended longitudinally. The inner wall, the outer wall and the upper wall are connected to form a tubular body around the bottom main body. Alternatively, the inner wall, the outer wall and the lower wall are connected to form a tubular body around the bottom main body. When deflated, the tubular body collapses due to gravity so that the outer wall is superposed on the inner wall.

Abstract: An inflatable product includes an inflatable body and a supplemental sheet. The supplemental sheet is connected to the inflatable body to form a space. When the inflatable body is inflated, the inflatable body is expanded due to increased air pressure therein and the space becomes reduced in size. Accordingly, when a portion of a sheet or a cover is put in the space and the inflatable body is inflated to reduce the space in size, the portion of the sheet or the cover is held by the supplemental sheet and the inflatable body.

Abstract: An inflatable product includes an inflatable body and a supplemental layer. The inflatable body includes a first wall and a first auxiliary sheet fused with each other. The supplemental layer is configured to cover the first wall and is fixed to the first auxiliary sheet of the inflatable body by sewing and/or gluing.

Abstract: An inflatable product includes an inflatable chamber and an elongated element. The inflatable chamber includes fusion portions. The elongated element is flexible, is disposed in the inflatable chamber, includes enlarged portions, and is connected to the inflatable chamber with the enlarged portions constrained by the fusion portions. The elongated element is in tension for controlling expansion of the inflatable chamber to a desired shape when the inflatable chamber is inflated to expand. The enlarged portions are constrained by the fusion portions to avoid separation of the elongated element from the inflatable chamber when the inflatable chamber is inflated to expand.

Abstract: An inflatable product includes an inflatable chamber and a supplemental layer. The supplemental layer is disposed on the inflatable chamber. Further, the supplemental layer is directly or indirectly fixed to the inflatable chamber by sewing. The inflatable chamber is made of plastic. The material of the supplemental layer is different from that of the inflatable chamber.

Abstract: A system and method for caching memory request verification data comprising a memory request generator configured to generate a memory request designating requested data and memory request verification data. A bus is configured to carry the memory request from the memory request generator to a cache memory that stores verification data, and upon receiving the memory request is configured to: retrieve stored verification data from the cache memory, compare the stored verification data to the memory request verification data, and responsive to a match between the stored verification data to the memory request verification data, designate a memory request validation. Also part of the system is a memory controller configured to, responsive to a memory request validation, retrieve data specified in the memory request from a main memory and provide the data to the memory request generator over the bus. A main memory configured to store the requested data.

Abstract: Provided by the present invention is a current overload protection apparatus. The apparatus comprises a current measuring device and a control module; the current measuring device is used to measure a current value on a current path; the control module is electrically connected to the current measuring device, and stores current threshold data; the current threshold data comprises a plurality of time intervals respectively corresponding to disconnection threshold values; the earlier the time corresponding to a plurality of time intervals, the larger the disconnection threshold value corresponding thereto; and the control module is used to receive and collect current signals within a specified time length so as to calculate the current value of the current path, and determine whether the current value is greater than or equal to the disconnection threshold values, and if so, then an overload protection step is performed to protect the load from current overload.

Abstract: A memory test system including a memory storing non-transitory machine executable instructions configured to generate test patterns. A processor or state machine is configured to execute the machine executable instructions to generate the test patterns. A memory controller receives the test patterns, writes the generated test patterns to a memory being tested, and reads the test patterns from the memory being tested to create read test patterns. A comparator or controller is configured to compare the generated test patterns to the read test patterns and responsive to differences between the generated test patterns and the read test patterns, generate a memory read error. Pass/fail registers may store data and a memory address associated with the memory read error. The test patterns can be stored for a period of time before being read to test the ability of the memory being tested to store the test pattern.

Abstract: A nozzle device includes a first passage, a second passage, and a first ambient valve clapper. The first passage includes a first intake and a first outlet. The second passage includes a second intake and a second outlet. The first ambient valve clapper is configured to control entry of fluid into the second passage through the second intake. The fluid is pumped to enter the first passage through the first intake to form a first negative pressure zone next to the first outlet, and the first ambient valve clapper is opened via a pressure difference between the first negative pressure zone and the surrounding of the nozzle device, allowing the fluid to flow into the second passage.
