BOHECS Divers' Voice Notifications System Report:

The purpose of this report is to provide an overview of the voice notification system developed for divers. The system aims to enhance safety and communication during diving operations by delivering voice notifications for various critical situations. Below is a list of the voice notifications included in the system:

Tide Table Notification: The system utilizes a free API to provide advance notifications about tide schedules based on the coordinates of the diving location.

Depth Exceedance: Notifications are triggered when a diver exceeds a predefined depth limit.

Dive Ascent/Descent Rate Exceedance: Notifications are activated when the ascent or descent rate exceeds 18 meters per minute.

Group Member Separation: Informs the diver if a group member moves more than 50 meters away.

Buddy Separation: Notifies the diver if the distance from the buddy exceeds 50 meters.

Regular Air Check Reminders: Provides periodic reminders to check air supply and respond to the group leader using a button interface. Options for response include preset percentages (25%, 50%, 75%) of remaining air volume.

Return Reminder: Regular reminders are given to ensure that at least one-third of the air supply is reserved for the return journey.

Movement Speed Warning: Alerts the diver about excessive movement speed, particularly in cases of encountering strong currents.

Rapid Temperature Change Warning: Notifies the diver about sudden changes in water temperature.

Warning for Strong Currents: Alerts the diver about the presence of strong currents that can carry inexperienced divers downstream.

Additionally, the system integrates voice notifications received from the dive boat to provide crucial updates and instructions. Examples of boat-to-diver voice notifications include:

"The boat has changed its anchor location, look for the new marker."
"Weather conditions are deteriorating, exercise caution during ascent."
"Exercise caution during ascent, there are multiple vessels in the area."
"Oxygen stations have been installed at a depth of 5 meters."
"Please provide an update on your status."
"Check and report the pressure in all participants' tanks."
"Wait at a depth of five meters, we will provide further instructions."
"You are diver number 3, pay closer attention to their activities."
"They have returned, participant number [number] has been accounted for."
"We are observing an interesting object at the specified location on the map."
"Exercise caution, other divers have reached the object."
"Danger."
The system is designed to enhance diver safety, improve communication, and provide timely information during diving operations. It serves as a valuable tool for ensuring the well-being of divers and facilitating effective coordination between the dive team and the dive boat.

Please note that the specific technical details and device specifications of the system are not included in this report but can be provided upon request.

If you require further information or have any questions, please do not hesitate to reach out.

Engineering Report on BOGEX Energy Transmission and Reception Blocks

Project Overview
"BOGEX" startup presents a unique, lightweight, floating cable with 5km 5kW resonant control sensors. The system features fiber optic security, perimeter temperature and gas sensors, remote carrier frequency adjustment, and energy source connection. It uses a lightweight, non-metallic composite cable system with a core conductor, allowing for intermediate consumers with attachable lens-hermetic connectors. Power module 380 inverter on batteries is also included.

Progress
Advancements in wide bandgap semiconductor technology, such as silicon carbide (SiC), enable the increase in the operating frequency of high-voltage (HV) and generators using a series of devices connected to the same nominal voltage RF generators. These generators are often equipped with HV multipliers like the Cockcroft-Walton cascade, resonant inverter, and high-voltage transformer. High-frequency energy conversion typically reduces system size and cost and increases efficiency.

Electrical Characteristics
Our model integrates key features of a classic coaxial cable including 75 +/- 3.5 Ohm wave resistance, 55 pF/m cable electric capacity, 1.22 wave length shortening coefficient, 15 mOhm/m connection resistance, and 82% wave propagation speed. Skin layer thickness for 60Hz is 8.5 mm, while it's only 0.02 mm for 10 MHz current.

Innovation and Improvements
Our team has developed a computer model of RF transmission theory, managed by a non-removable, patent-protected program algorithm. This software is accompanied by our durable hardware – a protective iron box and transfer coil.

Plans for Enhancement
While we strive for modularity and compactness, there are areas of improvement such as extending the cable length (to 1250m), minimizing dimensions, simplifying the schema without resonance, exploring the reliability and efficiency of resonance, and investigating new cable solutions (capacity, resistance) and materials.

Patent & Documentation
Several patents have been filed, including a control resonance block and a duplicated channel block. We provide a product passport, accompanying documents, transformer parameters, and all agreements as outlined in the contract.

System Configuration
Current configuration includes:

220V isolation block
5kW power output over 5km distance
Performance with a coil or 380V generator with inverter (battery operation is possible)
Automated cutoff switch
Battery power in case of receiver failure
Twisted pair of wires and multi-strands without coaxial on a 1250-meter test
Frequency range switch for the cable
Connection of diode lamps
We are continuously seeking better solutions to ensure our BOGEX blocks for energy transmission and reception remain cutting edge in the industry. The way forward involves continuous optimization and fine-tuning to achieve the ideal functionality of the system.
