Abstract:
A single event upset hardened memory cell to be utilized in static random access memories is disclosed. The single event upset hardened memory cell includes a first set of cross-coupled transistors, a second set of cross-coupled transistors, and a set of isolation transistors. The set of isolation transistors is coupled to the first set of cross-coupled transistors such that two inversion paths are formed between the cross-coupled transistors and the isolation transistors.
Abstract:
A multiplexor having a single event upset (SEU) hardened data keeper circuit is disclosed. The multiplexor includes a precharge transistor, an isolation transistor, an invertor, and an SEU immune storage cell. Both the gate of the precharge transistor and the gate of the isolation transistor are connected to a clock signal. The SEU immune storage cell has a first access node and a second access node. The first access node is complementary to the second access node. The first access node is connected to the precharge transistor and the second access node is connected to the isolation transistor. The invertor is coupled between the precharge transistor and the isolation transistor.

Abstract:
A single event effect hardening technique for removing glitches in digital logic circuits is disclosed. The noise immune latch circuit includes a first input, a second input, and an output. The noise immune latch circuit includes a first set of two cross-coupled transistors, a second set of two cross-coupled transistors, a first set of isolation transistors, and a second set of isolation transistors. The cross-coupling is accomplished by connecting a gate of each transistor to a drain of another transistor in a same set. The first and second sets of isolation transistors are respectively connected to the first and second sets of cross-coupled transistors such that two inversion paths are formed including the two sets of cross-coupled transistors and the two sets of isolation transistors. The noise immune latch circuit changes from one state to another state only upon having incoming input signals of identical polarity being applied contemporaneously at both the first input and the second input. In addition, a delay element is connected between the incoming signals and the second input. The delay element provides a signal delay time equal to or greater than a pulse width of a noise induced glitch but less than a pre-determined pulse width of an incoming signal under normal operation.
Abstract:
A kind of electric power-assisted bicycle is presented in the invention. Its characters consist in that: the electric-driving device 2 is composed of the flat motor installed in the shell and harmonic reducer; the shell body and storage battery are fixed in the middle of the frame; its center shaft crosses the flat motor and the harmonic reducer along with the axis line separately, and can rotate relatively to them; the mentioned flat motor is connected with the power-transmitting device through the harmonic reducer. The entire bicycle is lightweight and long-life, while it is also energy saving high efficient and can be conveniently assembled, used, carried and maintained.
Abstract:
Innovations in intra block copy (“BC”) prediction mode facilitate intra BC prediction that is more effective in terms of rate-distortion performance and/or computational efficiency of encoding and decoding. For example, some of the innovations provide ways to select block vector (“BV”) values more effectively. Other innovations provide ways to encode/decode BV values more efficiently. Still other innovations address how to perform in-loop deblock filtering when a block has intra BC prediction mode, or address how to perform intra BC prediction when constrained intra prediction is enabled.

Abstract:
Techniques for coding and deriving (e.g., determining) one or more coded-block-flags associated with video content are described herein. A coded-block-flag of a last node may be determined when coded-block-flags of preceding nodes are determined to be a particular value and when a predetermined condition is satisfied. In some instances, the predetermined condition may be satisfied when log2(size of current transform unit) is less than log2(size of maximum transform unit) or log2(size of current coding unit) is less than or equal to log2(size of maximum transform unit)+1. The preceding nodes may be nodes that precede the last node on a particular level in a residual tree.
Abstract:
The invention related to the recycling field of waste printed circuit boards (WPCB), and especially involved a complete non-cyanogens wet process for green recycling of WPCB, which belonged to the field of recycle economy. In the invention, the process included that WPCB were broken by the jaw crusher, and then mixed copper powders and nonmetallic powders were separated by the method of air classification, the mixed copper powders were smelted and casted to get copper anode plates, the copper was purified by electrolytion, the valuable metals (such as copper, gold, silver, platinum and palladium, lead and tin) were recycled from the copper anode slime, and the waste water was recycled. The recovery ratio of all-metal was above 98%. The purity of the cathode copper was up to 4N level. The ratio of de-coppering was above 96%. The recovery ratio of gold was above 98.
