　　据南京华讯美国专利报道，这种发动机被称为“不可能的引擎”，但一些人称可使人类去火星的旅程缩短至10周。没人确切知道该发动机如何工作。现在，利用微波在密闭缸里的反弹产生推力的EmDrive太阳能发动机，进行了升级。

　　该发动机的发明人罗杰·肖耶尔(Roger Shawyer)申请了新版EmDrive发动机的专利，包括安装一块超导板提高推力。新EmDrive推进器设计在一端安装了一块平整的超导板，在另一端安装了形状奇特的不导电板。这块板的作用是将内部多普勒频移降至最低，多普勒频移是指观察者相对波源移动时出现的频率或波长变化。这将使发动机的推力更为强大。

　　同时，由于超导板可以做成平面形状，也节省了制造成本。很多人质疑EmDrive发动机的概念过于夸张，暗示这种设计违反了物理定律。但今年其秘密将被揭开，NASA的实验室一直在研究这个概念，8月宣布有所发现并将在12月首次公布试验结果。EmDrive发动机的概念是罗杰·肖耶尔在2000年提出的。此后有4个独立实验室，包括NASA的那个，都再造了这种推力。

　　但这种神秘的发动机令科学家迷惑不解，因为这似乎违反了动量守恒定律，即每个力都会有大小相等、方向相反的一个反作用力。火箭喷出火焰产生推力使得火箭只能向前加速。NASA的Eagleworks团队准备公布其试验结果，其声明引起物理界的恐慌。一位用户在NASA太空飞行论坛上称：“我的理解是，Eagleworks的新论文已经被同行评论的期刊接受，准备出版。”

　　今年早些时候，一位职员证实该团队在写这篇论文。工程师保罗·马奇(Paul March)在同一论坛上写到：“Eagleworks实验室没有死，我们继续沿着NASA管理层设定的道路前进。除了罗德尔博士说的，我对该话题没有更多要说的，请耐心等待下一份EwDrive论文出版。”今年早些时候在AIP Advances上发表的论文暗示，EmDrive与其他火箭一样都要向外排出。

　　赫尔辛基大学物理学教授、论文的第一作者阿尔托·安尼拉(Arto Annila)博士称：“EmDrive工作原理与其他任何发动机一样，其燃料是微波长度的光子。”研究人员暗示，机器产生的光子会相互干涉，因此总体效应似乎是没有任何东西。“在密闭缸里光子会来回反弹，其中总有部分光子会产生完全破坏性的干涉。”然后2个光子将完全180度异相相消。

　　“在完全干涉电磁场里，2个光子将完全抵消，但光子本身会继续扩散。”这如同水波相遇，如果波峰与波谷正好重叠，就会相互抵消。但水不会消失。同样，一对光子也不会消失，即使无法作为光而看见，但依然带有动量。安尼拉称：“没有电磁场的成对光子将逃离密闭缸，从而形成EmDrive排出的能量。”

　　“当密闭缸是不对称的，如圆锥体一样，成对光子的排出也是不对称的。因此成对光子携带的动量损失是不一致的，换句话说，就是产生了推力。”安尼拉博士与Jyv?skyl?大学有机化学教授厄尔基·科尔曼宁(Erkki Kolehmainen)和工程软件公司Comsol的多物理学家帕特里克·格兰(Patrick Grahn)。他们写到：“没有排出能量的推力当然不可能出现，然而，某些密闭共振缸，在以微波为燃料时，会提供推力但没有可见的排出物。”

　　据南京华讯美国专利了解，他们的理论暗示，EmDrive也产生了排出物，只是看不见。安尼拉博士称，光子理论上可被干涉仪检测到，这种仪器也被用于检测引力波。他表示：“我的直觉是，很难检测到这么小的能量密度超量，特别是在EmDrive稳定运转时。但我们对排出物的想法在设计密闭缸让成对光子更好地朝一个方向排出，因而产生更多推力是有用的。”

Electronic Arts pledges free use for five accessibility patents

Electronic Arts pledges free use for five accessibility patents Recently, Electronic Arts (EA) announced a patent pledge that gives other companies and developers free access to five of its current accessibility-related patents and technology. The company promised not to enforce against any party for infringing any of the listed patents. Instead, EA hopes to encourage “innovation” and build new features that make video games more inclusive on a much larger scale by opening up the patents. Electronic Arts (EA) is an American video game company founded in 1982. The company owns many popular and famous games, such as The Sims, SimCity, Apex Legends, Madden NFL and FIFA. Each of the games has more than 30 or 50 million sales volume. Significantly, esports involves FIFA and Apex Legends into the event list. Apex Legends has up to 1 billion players, and it is so popular that it has a Switch version. Within the freely available patents, one of which grabs everyone’s attention -- Apex Legends’ ping system (patent No. US 11097189). The ping system in Apex Legends, which excellently allows players to make communication and teamwork quick and easy without hearing or speaking, has been praised both as an impressive alternative to voice chat and as a great accessibility feature for players with a variety of disabilities. The other patents include the technology widely used in the FIFA and Madden NFL. The innovations can automatically detect and modify colors (patent No. US 10118097 and CN 107694092) and contrast ratios (patent No. US 10878540) to improve gamers’ visibility with colorblindness and low vision. Furthermore, one of the patents relates to personalized sound technology, helping players with hearing issues by modifying or creating music based on their preferences (patent No. US 10790919). The code of the mentioned technology is published on EA’s GitHub, and it is open to all developers. Thus, the developers can use it or adapt it for their games without spending the costs to research. It is good that EA shares the patents for free use and aims to create an accessibility-increased gaming environment for players. However, it is not “unconditional” to use the listed patents. In the pledge, EA mentioned that it may terminate the promise for a specific party which files a patent infringement lawsuit or other patent proceedings against EA. We can see parts of EV’s ambition behind the announcement—to build a large game developer league and a community of shared interests.

Types of patents that are easily overlooked- Design Patent

Types of patents that are easily overlooked- Design Patent In recent years, as the public’s awareness of intellectual property has increased, people have begun to consciously use the patent law to protect their intellectual property rights. However, in the process of implementation, they often only focus on invention patent and utility model patent, and tend to ignore the protection of design patent. Recently, Midea sued Haotaitai for two models of CXW-300-D998 and CXW-300-D908 Haotaitai brand range hoods In the case of suspected infringement of its design patent (patent number: ZL201930621598.X), the Guangzhou Intellectual Property Court made a first-instance judgment after hearing that it determined that the two products of Haotaitai constituted infringement, and ordered it to immediately stop the infringement and compensate Midea, The company's economic losses and reasonable expenses totaled 360,000 yuan. In fact, appearance infringement cases have occurred from time to time before, such as: "Molly" blind box design patent case, "Siemens" switch design patent infringement dispute case received a compensation of 6 million yuan, three Casio watch design patents were infringed Received a compensation of 8.8 million yuan and so on. The reason why people ignore the protection of design patents, in the final analysis, is that they have insufficient knowledge of design patents. Today, let's take a look at what is protected by design patents and what rights protections can we apply for? Design patent definition: Article 2 of the "Patent Law", design patent, refers to a new design that is aesthetically pleasing and suitable for industrial applications based on the shape, pattern, or combination of products, and the combination of color, shape, and pattern. Protected range: The shape of the product; the pattern of the product; the shape and pattern of the product; the shape and color of the product; the pattern and color of the product; the shape, pattern and color of the product. Protection period: The term of protection for design patent rights is 15 years, calculated from the date of filing. What are the conditions for applying for a design patent? The design should be aesthetically pleasing Appearance patents should be suitable for industrial applications The design patent application should be novel The design patent application should be inventiveness What are the advantages and functions of design patents? Protect the rights and interests of enterprises in product designs and fight against infringements in market competition. To enhance brand value, the quality and quantity of patents are the embodiment of the company's innovation ability and core competitiveness. Receive consumer recognition. If a company's new product appearance is filed for a patent in a timely manner, its appearance design will enjoy the exclusive right. Nowadays, consumers often choose products with trendy and beautiful appearance when buying their products. Applying for a design patent is a necessary condition for applying for a high-tech enterprise.

Colopl Settles Patent Infringement Lawsuit with Nintendo by Paying $30 Million

Colopl Settles Patent Infringement Lawsuit with Nintendo by Paying $30 Million This August, Nintendo and a game developer Colopl announced that they have settled for patent infringement regarding White Cat Project (Shironeko Project in Japanese), a smartphone game developed by Colopl. Although both companies did not publicly share exact details of the settlement, at least it is sure that Colopl agreed to pay 3.3 billion yen (about US$30.2 million) as the settlement fee for the proceedings, including the future license of Nintendo's patents. How did the battle begin? Being developed and published by a Japanese game developer, Colopl, White Cat Project is a free-to-play action role-playing game for Android and iOS systems. The mobile game was launched in July 2014 as well as got a television anime adaptation in 2020. It is incredibly popular to have more than 50 million downloads. Furthermore, the game is set to receive a Switch version titled "Shironeko New Project". In September 2016, Nintendo noted the Colopl's game and considered that the game had infringed on several of Nintendo's technology patents. The two companies communicated with each other for over a year; however, Nintendo did not accept the explanations from Colopl, and Nintendo filed a lawsuit against Colopl at the beginning of 2018. Nintendo claimed that Colopl infringed 6 of its patents. These patents protect touch-screen joystick functionality (patent no. JP3734820), multiplayer connectivity (patent no. JP5595991, JP6271692), confirmation screens in sleep mode (patent no. JP4010533), character attacks based on touch input locations (patent no. JP4262217), and a shadow effect placed on characters hidden behind the game geometry (patent no. JP3637031). These patents almost cover various ways of game technology, especially the patent JP5595991 and JP6271692. Their patent family is wide-reaching, and many divisional applications of the family are pending in Japan. They protect a communication game system and its related devices. It is not easy to detect the patent's existence and boundary since this kind of hardcore technique is so common in the gaming field and our daily lives. The five-year patent war has been settled. After a five-year dispute, the situation appeared to turn in Nintendo's favor as the Switch maker increased its monetary demands, which convinced Colopl to strike a deal that lets it use the disputed patents. Furthermore, a Switch version of White Cat Project remains in the works at Colopl. With the extraordinary losses of Colopl, the legal battle between the two companies came to an end.
