Abstract:
The present utility invention disclosed a technical field of height-increasing seat cushions, in particular to a SPA cushion, comprising a outer jacket and a core. There are counterweights at the bottom of the core. The outer jacket and the core are made of a 3D mesh material. The bottom of the outer jacket is provided with non-slip rubber base for increasing friction, and four mounting holes for installing suction cups. Compared with other inflatable cushions on the market, the SPA cushion is high of air and moisture permeability and redistribution of compression pressure due to the 3D mesh material. And it offers comfortable and significant support for the buttock; Also, since the outer jacket and the core are made of 3D mesh material, it becomes more breathable and quick-drying. The weight of the counterweight will drive the SPA cushion to sink and fix it on the bottom itself easily when use in water. The non-slip rubber base at the bottom side of the outer jacket increases the friction, in result, the SPA cushion will not move or float casually, which makes it more convenient to use. The suction cups can prevent the SPA cushion from moving, too. And compared with these existing inflatable seat cushions, the SPA cushion is of higher quality, and there is no problems such as air leakage and explosion.
Abstract:
A cascade converter station and a multi-end cascade high-voltage direct current (HVDC) power transmission system. The converter station includes a low-voltage end converter station (11) and a high-voltage end converter station (12). The high-voltage end converter station (12) is connected in series with the low-voltage end converter station (11) through a medium-voltage direct current (DC) power transmission line (13) and connected to a HVDC power transmission line (14). With the cascade converter station and the multi-end cascade HVDC power transmission system, HVDC power transmission can be achieved in a flexible, reliable and economical manner.
Abstract:
The present invention comprises chlorinated and non-chlorinated alkaline cleaning compositions for removal of proteinaceous and fatty soils at low temperature, i.e. less than 120° F., with little or no deleterious affect on cleaning performance. According to the invention, applicants have found that adding additional alkalinity makes protein removal more difficult and reducing the amount of alkalinity actually improves performance. According to the invention optimized combinations of chlorine and alkalinity components for low temperature cleaning as well as a surfactant system optimized for low temperature fatty soil removal are disclosed.

The support assembly includes a hollow support detachably connected to the rear cover, at least one second conductive member connected to the hollow support and staying in contact with the at least one second conductive member, and at least one cable extending through the hollow support and comprising a first end electrically connected to the at least one second conductive member, and a second end extending out of the hollow support for connecting with a peripheral.
Abstract:
A system and method for defect analysis are disclosed wherein a defect data set is input into the system. A radius value is selected by a user, which is the maximum number of bits that bit failures can be separated from one another to be considered a bit cluster. When a defect data set is received, the system and method start with a fail bit and search for neighboring fail bits. The specified radius is used to qualify the found fail bits to be part of the bit cluster or not. If a minimum count of fail bits is not met, the system and method will stop searching and move to the next fail bit. If a minimum count of fail bits is met, the search continues for the next fail bit until the maximum fail bit count specified by the user is reached. Aggregation is provided such that once bit clusters have been classified, the number of clusters that have the exact match or partial match to each other is counted. The user may set the partial match as a threshold count to establish a match.
Abstract:
A light guide plate includes: a light emitting surface; a bottom surface opposite to the light emitting surface; a light incident surface perpendicularly connected with the light emitting surface; a first side surface perpendicularly connected with both the light incident surface and the light emitting surface; a second side surface opposite to the first side surface; two protrusions outwardly extending from the first side surface; and two protrusions outwardly extending from the second side surface. A thickness of each protrusion of the first side surface decreases with increasing distance away from the light incident surface, and a thickness of each protrusion of the second side surface also decreases with increasing distance away from the light incident surface.
