Indoor Positioning Virtual Network Computing for Lab Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication between integrated or dedicated computers in laboratory environments and mobile processing devices, such as tablets, is not seamless, especially when lab technicians need to access instruments or systems while being mobile, due to differing security protocols and hardware configurations.
Innovation Solution
A system combining indoor positioning systems (IPS) with virtual network computing (VNC) on mobile devices, allowing automatic authentication and data display in a familiar format by determining the technician's proximity to laboratory instruments or systems and launching remote desktop sessions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lab technician uses a mobile processing device to access laboratory instruments, then mobility is improved, but authentication complexity and hardware compatibility issues increase
Solution Approach 1:
The system enables self-service authentication by automatically detecting the technician's location via IPS and initiating VNC connections without manual intervention. The mobile device autonomously authenticates with the instrument by receiving credentials from the instrument's computer, eliminating the need for technicians to manually navigate security protocols or configure hardware settings.
Solution Approach 2:
The system introduces an intermediary authentication mechanism where the mobile device communicates with the instrument's computer through a standardized interface. This intermediary layer handles the complexity of authentication and hardware compatibility, allowing the mobile device to access instruments without directly interfacing with their proprietary security systems.
2Adaptability or versatility
If a workstation interface is used to access multiple computers, then access to multiple instruments is improved, but technician mobility deteriorates
Solution Approach 1:
The system transitions from a static workstation-based access model to a dynamic mobile access model. The mobile device continuously updates its location through IPS and dynamically establishes VNC connections with instruments based on real-time proximity, enabling technicians to access multiple instruments while moving freely throughout the laboratory space.
Solution Approach 2:
The mobile processing device serves multiple functions: it acts as a location sensor (IPS client), a communication interface (VNC client), and a display device. This multi-functional approach replaces the dedicated workstation, allowing a single mobile device to provide universal access to multiple instruments throughout the laboratory.
3Reliability
If manual navigation of instrument security and hardware is required, then security control is improved, but time consumption increases
Solution Approach 1:
The system performs preliminary authentication setup by having instruments pre-configure their security credentials and communication interfaces. When a technician approaches an instrument, the authentication process is already prepared and can be automatically initiated, eliminating the need for manual security navigation while maintaining secure access controls.

AI summary
A system that combines an indoor positioning system (IPS), virtual network computing (VNC), and at least one mobile processing device, e.g., a tablet computer. The IPS determines the location of the mobile processing device, from which information a most proximate instrument, device, and/or system can be determined. Once the most proximate instrument, device, and/or system is determined, the mobile processing device is adapted to launch a remote desktop session with the instrument, device, and/or system via the VNC. Advantageously, the launched remote desktop session automatically authenticates with the software of the instrument, device, and/or system and, moreover, displays data from the instrument, device, and/or system on the at least one mobile processing device in a format with which an operator is most familiar.
