MindMap Gallery Medicine-Visual Organs
Exclusively for medical students at the end of the semester, the visual organ consists of the eyeball and its auxiliary device. It is an important organ for people to live, work and connect with the environment.
Edited at 2023-12-17 20:02:50This is a flowchart illustrating the process of archiving monthly failure analysis reports and tracking the implementation of improvement measures. The diagram is structured into five main steps, each with specific tasks and sub-tasks.Monthly Report Collection & Organization: This step involves collecting failure analysis reports from various departments, reviewing them for completeness, and categorizing them by product, failure mode, and severity. Root Cause Analysis & Statistics: Here, the focus is on categorizing causes, analyzing trends, identifying root causes, and compiling statistics on high-frequency failure modes and key components. Improvement Measure Formulation & Assignment: This step includes formulating improvement measures, assigning responsibilities, and setting timelines for implementation.Measure Implementation Tracking & Verification: It involves tracking the progress of implementation, verifying effectiveness, and confirming issue closure.Knowledge Base Update & Monthly Report Output: The final step covers archiving reports, updating the knowledge base, and compiling monthly summaries.This template can be easily reused and adapted using tools like EdrawMind to suit different organizational needs.
This is a timeline infographic detailing the annual product certification acquisition countdown process, structured into four sequential phases. The first phase, Certification Planning & Initiation, encompasses goal setting, timeline planning, resource preparation, defining specific certification objectives such as CCC/CE/FCC, formulating an annual plan with key milestones, and allocating necessary budget, personnel, and sample resources. Following this, the Application & Testing Phase involves material submission, coordination with certification agencies, core testing procedures, preparation of technical documents, application forms, and samples, selection of the appropriate certification agency, and execution of critical safety, EMC, and RF tests. The subsequent Rectification & Acquisition Phase focuses on addressing and rectifying any identified issues, re-verification processes, acquisition of the certificate, analysis of test issues, implementation of necessary fixes, and modification of samples for supplemental testing. Finally, the Countdown Monitoring phase emphasizes tracking progress, managing risks, monitoring remaining days and key milestones, managing time, technical, and cost risks, and maintaining effective internal and external communication throughout the process. This comprehensive template can be readily reused and adapted using tools like EdrawMind to meet diverse organizational requirements.
This is a flowchart detailing the weekly update and review plan for technical documents. The process is divided into six main stages, each with specific tasks and responsibilities. It begins with Weekly Planning, where the document scope is defined, update objectives are set, and schedules are arranged. Next, Document Updates involve maintaining various documents such as hardware design documents, test specifications, and BOM tables, alongside version control and archiving. Internal Review Preparation follows, focusing on compiling review materials, identifying participants, and setting agendas. The Review Meeting stage includes document examination, problem discussion, decision recording, and responsibility allocation. After the meeting, Review Feedback Processing takes place, involving issue tracking, document modification, quality checks, and closure verification. Finally, Output Deliverables are prepared, including official release versions, release notifications, review reports, and plans for the next week. This structured approach ensures systematic and efficient management of technical documents, and the template can be easily adapted using tools like EdrawMind.

eyeball
Function
Location
eye axis
visual axis
From the center of the pupil to the fovea fovea
composition
eyeball wall
fibrous membrane of eyeball
cornea
Top 1/6
Colorless, transparent, elastic
Avascular, with sensory N terminals
Large curvature, refractive effect
sclera
