We will exhibit at CareTEX Tokyo '24 (Summer) from July 30 to August 1.

A "portable intercom" with excellent robustness that connects via wireless LAN/LTE.

We propose a solution! It will lead to improved operational efficiency! The IP210H is a portable internal phone equipped with a transceiver function for IP telephony. It allows calls between devices on the same LAN, and by using an LTE connection, it can send and receive internal and external calls from anywhere within the mobile phone coverage area. Additionally, by utilizing the transceiver function, you can contact multiple devices simultaneously, enabling rapid information sharing. ■ Connect via LAN or LTE Devices on the same LAN can communicate with each other through an access point, and calls can also be made via an LTE connection. ■ Simultaneous calls possible You can interrupt a call with someone else without waiting for them to finish. ■ Smarter with Bluetooth functionality Using compatible earphones and microphones allows for active calls without worrying about cables. ■ Long-lasting large-capacity battery with approximately 30 hours of operation You can use it for extended periods without worrying about battery life. *In WLAN wireless device + IP wireless device mode (communication mode: wireless LAN).

• PBX/IP phone

Intercom compatible with wireless LAN/LTE connections, easy to install, and can work with various devices.

We propose a solution! It will lead to improved operational efficiency! The IP200PG is an intercom that can work with wireless mobile IP phones (IP210H, IP200H) as well as fixed and mobile phones. ■ Supports wireless LAN/LTE connections The IP200PG can be connected via wired LAN, but it also allows communication through wireless LAN access points and LTE connections. ■ Easy installation and flexible expandability By utilizing wireless LAN, it can be installed more easily without being limited by location. It can also easily accommodate expansions. ■ Can make calls with fixed and mobile phones By connecting the internal (in-house) LAN to the optical phone via the SIP server SR-8000V, it enables calls with external lines (public lines). ■ Allows calls with IP200PG installed outside or staff on the go (wireless mobile IP phone IP200H) By introducing the RoIP gateway VE-PG4 that connects LAN and LTE lines, you can make internal calls from the intercom IP200PG to an IP200PG installed outside (with SIM) or to staff on the go (IP200H).

"Response to Increased Demand" - A 5W transceiver that offers "high quality at a low price," the second product under the 'Wedge Talkie' brand.

We propose a solution! It will lead to improved operational efficiency! WED-NO-301 is our original digital simple radio (registered station). It was completed through joint development with the major domestic radio manufacturer "Icom." With the concept of "domestic production, low price, and high quality," it features a simple and sophisticated design. ■ Supports channel expansion (35ch → 97ch) You can operate comfortably without interference due to a lack of channels. ■ Reliable domestic production High quality is achieved under a strict quality control system. ■ Bluetooth compatible You can use it comfortably without worrying about cords or button operations, thanks to hands-free functionality. ■ Dustproof and waterproof With an IP67 equivalent dustproof and waterproof performance, it can be used safely outdoors and at construction sites. ■ Easy operation Due to its simple design, it is very easy to use. There is no need to worry even for those using a transceiver for the first time.

To construction and civil engineering companies looking for the "next" step in digitalization. This seminar will explain the currently trending topic of "AI utilization" in 45 minutes. We will clearly introduce the latest trends, specific case studies, and steps for implementation to address questions such as "What can AI do?" and "How can it be applied to our business?" Whether your company is already advancing in DX or is just starting to consider AI, you will find hints for improving operational efficiency. 【Schedule】 1: Company introduction and instructor introduction 2: Case studies of AI utilization in the construction and civil engineering industry 3: Convincing examples! Patterns of AI utilization in construction operations 4: Three steps to avoid failure in AI implementation 5: Q&A and closing remarks

We will address the issue of young employees who, despite joining the company, leave due to reasons such as "there's no time to be taught," "I don't understand when I'm told to learn by watching," and "what is written and said varies depending on the project or person in charge." We propose a system that accumulates the know-how of veterans in AI and systems, allowing young employees to search for and solve problems on their own. 【Schedule】 1: Company introduction and instructor introduction 2: Reasons why technical inheritance is not progressing (lack of time, difficulty in verbalizing) 3: "Next-generation manual and know-how sharing methods" utilizing video and AI search 4: Examples of system construction to institutionalize technical inheritance 5: Q&A and closing remarks

[Instructor] Takahisa Saito, Human Resources Consultant, Saito Social Insurance and Labor Office [Key Lecture Content] Human resource systems support the foundation of an organization. However, if the operation is neglected, the system itself will collapse. There are various systems, but among them, the "grade system, evaluation system, and wage system" can be considered the three major elements. We must design these three major elements with the operation in mind. In other words, it is important that the system is easy for management to operate. There is no need to overthink it. Additionally, as work style reforms progress, we must also consider the response to equal pay for equal work. I believe that what lies ahead after organizing the current situation is the "limited regular employee." In this seminar, we will share anticipated information and provide clear explanations. Furthermore, for those attending in person, meaningful information exchange is possible through questions and mutual confirmation. [Lecture Items] 1. Trends and Perspectives Surrounding Human Resources 2. Basics of the Grade System 3. Basics of the Evaluation System 4. Basics of the Wage System 5. Considering Equal Pay and Job-Based Employment 6. Q&A / Business Card Exchange
