International Classification:

G09B003/00

US Classification:

434350000

Abstract:

An Internet compliance training system having a relational database for storing training data and a server for connecting to user computers through the Internet to provide training by presenting the training data, such as text, audio and image files. The training data is prepared with the training needs of specific users and groups of users in mind, with the purpose of providing training in those areas that the specific trainees can use to avoid risk of non-compliance. When a user signs-on, the system recognizes them and provides customized training content to them. The system is interactive with the trainee, giving the trainee control over presentation rate and order, such that the custom content is retrieved and delivered dynamically. The system has a subscription management system to automatically email trainees to induce them to take and finish courses, a testing system to verify that trainees fully comprehend content and a tracking system that records the course content that trainees have taken. The system has a timer to prevent a trainee from clicking through a course without reviewing it.

Abstract:

An autonomous sailing vessel may include a hull, a mast, a sail, and a sail release device. The mast may be mechanically coupled to the hull. The sail may be mechanically coupled to the mast. The sail release device may be operably coupled to the sail and may be configured to automatically release the sail to spill excess wind. Alternatively or additionally, the sail may include a fore sail element coupled to the mast and an aft sail element rotatably coupled at a fore of the aft sail element to an aft of the fore sail element. In this and other embodiments, the autonomous sailing vessel may further include a camber control assembly to automatically set a camber angle between the fore and aft sail elements.
