Electronic device that is fully sealed and has no external interface

Electronic devices that are fully sealed and have no external interfaces, especially portable electronic devices, have always been the goal of the industry. As early as a few years ago, the industry began to speculate which manufacturer would pick the fruit first, and once put expectations on Apple. With the release of the new iPhone, progress began: wireless charging was adopted in high-volume portable products. At the same time as the power supply began to achieve breakthroughs, as another core function to realize fully sealed and interfaceless electronic devices, high-speed data contactless connection technology began to receive more attention in the industry. In this area, Keyssa, headquartered in Silicon Valley, was established in 2009. With its more than 200 patent applications, Keyssa is committed to recreating connectors. Based on its proprietary solid-state connectors, the company has developed a breakthrough KissConnectivity solution that uses ultra-high frequency (EHF) technology to provide low-power, high-speed data transmission safely and easily. Breaking the bottleneck of industrial design innovation In September of this year, Keyssa announced the introduction of high-speed, ultra-small-area and ultra-low-power KSS104M and KSS104M-CW contactless connection solutions. Several key features of the KSS104M: 3x3mm package with built-in antenna; support for a variety of high-speed video and data communication protocols, including USB 2.0; running at speeds up to 6Gbps. As a new generation of component-based contactless connector products, the KSS104M has improved electrical and mechanical tolerance, while reducing power consumption and supporting a variety of high-speed communication protocols that are the industry standard. Keyssa will also release an instantly available contactless connectivity module, KSS104M-CW (Connected World Project), which meets all electromagnetic and mechanical requirements critical to the system for successful use of KSS104M in mobile and other system applications. .

Figure: Two generations show samples, the lower part is its new generation. The KSS104M is a miniature, low-cost, low-power, all-solid-state electromagnetic connector that moves large files at high speed and safely between devices. Like previous generations, the KSS104M can be easily integrated into a customer's end product while supporting multiple high-speed data and video protocols as industry standards without any changes to the software or firmware. The KSS104M-CW is a KSS104M-based electromagnetic module system designed to solve problems such as power supply, mechanical attachment mechanisms, and recommendations for waveguide transmission support (including color and finish) and material requirements. The module enables faster time to market for products using highly reliable contactless connectors in a variety of applications. The KSS104M-CW marks Keyssa's vision for commercial applications, including the elimination of cables by mobile phones, the elimination of unreliable mechanical connectors and the interference they generate, providing far more data throughput than wireless networks can support.

Figure: Remove the external interface of the device. Getting rid of more cable connections will undoubtedly lead to innovation in industrial design. “In the past, mechanical connectors were a limitation that couldn’t be undone, and this is constantly being broken,” said Steve Venuti, vice president of marketing at Keyssa. “The advantages are not just that, and the wireless connector can greatly simplify traditional manufacturing. The process supports high-volume and high-yield production in terms of manufacturing yield and reliability.” Venuti demonstrated some of the electronic devices with no connection at all, including mobile hard drives and portable computers. From his sharing point of view, this new connection method has a wide range of applications, including large-scale devices such as communications and high-speed data connections between different circuit boards inside portable devices.

Figure: Steve Venuti explains why the connector has to be reinvented. Building an ecosystem It is reported that as one of Keyssa's investors, Foxconn's Hongsheng Precision Technology (FIT) is building a high-speed contactless connector module KSS104M-CW that can be integrated into various systems. “The KSS104M-CW was designed with our proposed Connected World program,” said Steve Venuti, vice president of marketing at Keyssa. “Our ecosystem partners need to know that high-speed connections can be easily and reliably implemented in the system. It is implemented in large quantities of up to 100 million meters, and its system material cost (BOM) is still very low.” The above mentioned “Connected World” is a disruptive smartphone ecosystem jointly launched by Foxconn, Keyssa and Samsung. In terms of defining how next-generation mobile devices can share gigabit-level data without Wi-Fi or cable, the program radically simplifies engineering and design requirements for consumer IoT devices and applications, including mobile Application scenarios such as homes and cars. The core element in building the Connected World ecosystem is Keyssa's proprietary Kiss Connectivity connectivity technology. Improve functionality and simplify engineering and design by breaking through the limitations of using cables and Wi-Fi for decades. Connected World will simplify the sharing of large data between smartphones, peripherals, accessories, smart homes and cars, and dramatically speed up the synchronization – simply by bringing the devices together, you can achieve gigabit-level data transfer. Key components of the specification include mechanical attachment mechanisms for equipment, high-bandwidth electromagnetic channel requirements, and compliance testing of equipment. Keyssa will provide a license for all of its IPs in the specification, including its system-level patents. When the specification is made public, a reference design will be provided to the manufacturer. "The first iPhone has been around for 10 years, and this device defines the center of our digital life," commented Tony Fadell, the inventor of the iPhone. "But in terms of connectivity and device interaction, we only implement A small part of its potential. Soon we can see very high-speed connections between cars, home devices and mobile phones, and it is creating a truly connected world without the need for expensive mobile data connections." Now, We can begin to look into a world where cables and mechanical connectors are no longer needed between devices without sacrificing bandwidth or security.
