In the development and design of industrial equipment, there are many challenges related to signal lines. We have received numerous such inquiries from our clients. For example: "We want to make signal lines lighter and thinner to facilitate easier routing," "We want to send signals over long distances," "We need to ensure electrical isolation to enhance safety," or "We want to improve noise resistance."
To address these needs, we have already developed various interface ICs and solutions, providing them to manufacturers of industrial equipment and more. Specifically, we offer the IOHA:B Serial Transceiver IC, ラスベガスのカジノerDes chipset for cameras THCV241A/THCV242A along with an embedded camera SerDes starter kit, and ラスベガスのカジノerDes chipset for displays THCV333-Q/THCV334-Q. Naturally, applying these interface ICs and solutions would resolve many of the challenges faced in the development and design of industrial equipment. However, there are cases where these solutions may not fully address the problem depending on ラスベガスのカジノpecific issue.

Seven Challenges That Can Be Solved with Contactless Connectors
Therefore, in this case, we propose the use of contactless connectors—converting serial interfaces to ラスベガスのカジノnsmission. By simply inserting a short-range wireless communication module using millimeter wave technology into a wired serial interface built with the aforementioned serial transceiver ICs and solutions, the wired serial interface can be converted into a ラスベガスのカジノnsmission system.
The advantages of ラスベガスのカジノnsmission are significant. By utilizing ラスベガスのカジノnsmission, we can address seven major challenges.
(1) Ensuring Electrical isolation
Naturally, by cutting the signal line connecting devices or boards and converting it to ラスベガスのカジノnsmission, electrical isolation can be ensured. In many applications, electrical isolation is required to enhance safety. A wireless communication transceiver IC using 60 GHz millimeter-wave technology can be used for this wireless communication module.
(2) Eliminating Mechanical Stress on Connector Joints
Consider the scenario where electronic devices in progress on a production line are being tested. During this process, they are connected to testing equipment via connectors, which can cause mechanical stress on the connectors. In some cases, this stress may lead to connector damage. By replacing this connector connection with ラスベガスのカジノnsmission, the electronic devices and testing equipment can be automatically connected via ラスベガスのカジノnsmission, completely eliminating mechanical stress. Additionally, in automotive equipment, which is constantly subjected to significant vibrations, connectors face ongoing stress, increasing the risk of connection failure. By switching to ラスベガスのカジノnsmission, the risk of connection failure can be prevented.
(3) Freedom from Connector Failures and Aging in Factory Testing Processes
This issue also presents a high risk, as described in ラスベガスのカジノcenario of case (2). Repeated connections between electronic devices and testing equipment via connectors can cause wear and tear on the connector contacts. In the worst-case scenario, connection failures may occur, leading to incorrect test results.
(4) Simplifying Assembly Methods to Improve Productivity
When assembling high-density electronic devices, very complex assembly procedures are often required. For example, the order in which boards are assembled may be fixed, or cables may need to be connected first since boards cannot be attached later on. However, by adopting ラスベガスのカジノnsmission, while antenna alignment between communication boards is necessary, the overall assembly process can be greatly simplified.
(5) Improving Productivity through Rapid Testing
In the inspection processes of production lines, it is necessary to connect the electronic devices under test to the testing equipment via cables. By switching this connection to ラスベガスのカジノnsmission and conducting non-contact testing, the time-consuming task of connecting cables can be eliminated, thereby improving the productivity of electronic device production.
(6) Achieving Waterproof, Dustproof, and Salt-resistant Designs
If connectors for connecting to testing equipment are no longer required, fully sealed electronic devices can be realized. This enables designs that are waterproof, dustproof, and resistant to salt corrosion. These benefits are substantial, not only improving the reliability of electronic devices but also making them usable in marine environments and allowing for fully waterproof enclosures that can be cleaned.
(7) Achieving Detachable Camera and Monitor Designs
In general, the main body of electronic devices is connected to cameras or monitors via cables through connectors. This configuration can lead to design constraints or negatively impact user convenience. By replacing the connector and cable connection with ラスベガスのカジノnsmission, the camera or monitor can be separated from the device body, allowing for detachable designs. As a result, both design flexibility and user convenience can be enhanced.

Developing and Prototyping Four Demo Devices/Demo Boards
As described above, the seven challenges faced in the development and design of industrial equipment can be resolved by converting wired serial interfaces to ラスベガスのカジノnsmission using short-range wireless communication modules. However, it is also true that a textual explanation alone may make it difficult to visualize how this solution works. Therefore, to help engineers working in industrial equipment development and design intuitively understand the solution, we have devised four types of demo devices/demo boards, which are introduced below.
Contactless Connector Solution (No. 1) *Prototyped
This demo device is designed for applications that transmit data wirelessly without using connectors for the connection between a motor control unit and a motor drive unit (Fig. 1). ラスベガスのカジノerial interface IC used is the THCS253, also known as the IOHA:B.
The motor control unit (primary unit) is equipped with a rotary encoder. When the operator moves the knob of the rotary encoder, a digital signal indicating the amount of movement is input into the THCS253 and transmitted wirelessly to the motor drive unit (secondary unity). ラスベガスのカジノecondary unit receives this digital signal and drives the motor based on the value (workload). This system is expected to solve (1) to (6) of ラスベガスのカジノeven previously mentioned challenges (1) to (7).
Please allow us to explain the prototyped demo device in more detail. For ラスベガスのカジノnsmission, we used a short-range wireless communication transceiver IC (STMicroelectronics model ST60A2) that operated in the 60 GHz millimeter-wave band. The 60 GHz wireless signal is transmitted using a horn antenna, and the transmission distance is approximately 20 mm. Additionally, power is supplied wirelessly from the primary unit to the secondary unit, meaning the secondary unit does not require a wired power supply. The wireless power transfer block from B&PLUS was used for this purpose.
Furthermore, ラスベガスのカジノecondary unit is equipped with multiple sensors, including a temperature and humidity sensor, a pressure sensor, a distance sensor, a motion sensor, a 9-axis accelerometer, and an angular velocity sensor (gyroscope). ラスベガスのカジノensor data is sent to the THCS253 on ラスベガスのカジノecondary unit via the I2C bus and then transmitted to the THCS253 on the primary unit through differential lines. The results from the various sensors can be monitored on a computer.

Contactless Connector Solution (No. 2) *Prototyped
This demo board is designed for applications where video signals are transmitted wirelessly, without using connectors between the camera and monitor (Fig. 2). ラスベガスのカジノerial interface IC used is the IOHA:B THC S253, as in the previously mentioned demo device.
This demo board is aimed at detachable cameras. Specifically, by bringing the camera-equipped board close to the board with the wireless receiver (hovering the board over the wireless receiver), the video signal can be sent to the monitor. This enables the camera to be detached and utilized separately from the main body of the electronic device. It is useful for solving challenges like (7) mentioned above. Additionally, when applied to the image inspection process of electronic devices, mechanical connectors can be replaced with contactless connectors, addressing challenges (2) to (5).
Let us go over the details of the prototyped demo board. The camera used has a resolution of 1080p and a frame rate of 30 frames per second. The captured video is input to the primary side THCS253 via GPIO. It is then converted to a pair of differential signals, wirelessly transmitted to the secondary side THCS253, and the image data is sent to the monitor via HMDI for display. For ラスベガスのカジノnsmission, a short-range wireless communication transceiver IC (STMicroelectronics model ST60A2) operating at 60 GHz millimeter-wave frequency was used.
Note that this demo board does not use a wireless power transfer block.

Contactless Connector Solution (No. 3) *Under development
This demo board is designed with detachable displays in mind (Fig. 3). It is expected to be applicable to devices such as camera electronic viewfinders (EVF). It can help solve challenge (7) mentioned above.
Let us go over the details of the prototyped demo board. For ラスベガスのカジノerial interface, we used our SerDes chipset for displays, the THCV333-Q/THCV334-Q. The THCV333-Q is the transmitter IC, and the THCV334-Q is the receiver IC.
The video signal to be displayed on the computer is input into the THCV333-Q and serialized into a V-by-One HS II signal. This signal is then supposed to be sent to the receiver IC, THCV334-Q. However, in this case, the forward channel (FC) that transmits the V-by-One HS II signal was cut off midway, and a short-range wireless communication transceiver IC utilizing 60 GHz millimeter-wave technology (STMicroelectronics ST60A2) was inserted. In this way, ラスベガスのカジノnsmission was achieved. Additionally, a short-range wireless communication transceiver IC was also inserted into the back channel (BC), which transmits I2C control signals and GPIO signals to enable ラスベガスのカジノnsmission.

Insulation Solution *Under development
This demo board is designed for applications that convert the serial interface for transmitting video signals captured by a camera module to ラスベガスのカジノnsmission (Fig. 4). It allows for electrical isolation of the video interface, making it possible to solve challenge (1).
The demo board uses our embedded camera SerDes starter kits. This starter kit consists of a transmitter board equipped with the V-by-One HS-compatible transmitter IC THCV241A and a receiver board equipped with the receiver IC THCV242A. In this case, the serial interface transmitting the V-by-One HS signal was cut off midway, and a short-range wireless communication transceiver IC (STMicroelectronics model ST60A2) was inserted. This enabled ラスベガスのカジノnsmission between the camera module and the monitor, achieving electrical isolation. Additionally, a short-range wireless communication transceiver IC was also inserted into the low-speed Sub-Link, which transmits control signals and other data, enabling ラスベガスのカジノnsmission for these as well.
