Session State Transfer to Mobile Device for Remote Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators face challenges in coordinating control interventions with remote tasks in environments where tasks are performed at a distance from a control console, such as in laboratory settings with in vitro diagnostic instruments, due to the need to interact with central computer displays while performing physical activities.
Innovation Solution
The session-state of a local user interface is transferred to a mobile device, allowing operators to execute remote tasks while maintaining interaction with a central controller using indicia such as RFID, QR codes, or near-field sensors, enabling control execution regardless of location, and preventing input/output conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator interacts with the central computer display to perform control tasks, then the control operations can be executed accurately, but the operator must be physically present at the central console which reduces operational flexibility and increases travel time between tasks
Solution Approach 1:
The patent creates a mobile replica of the central control interface by transferring the session state to a mobile device. The mobile device displays and accepts inputs for the same diagnostic workflow, instrument controls, and alerts as the central console, enabling operators to perform control tasks at any location without physically traveling to the central display.
2Adaptability or versatility
If the session state is transferred to a mobile device, then the operator can execute tasks remotely with improved flexibility, but coordination between the central controller and mobile device must be maintained to prevent control conflicts
Solution Approach 1:
The system implements continuous feedback mechanisms where the mobile device and central controller exchange status information in real-time. The session state transferred to the mobile device includes current instrument status, pending alerts, and workflow progress. The system monitors for potential conflicts and ensures that actions initiated from the mobile device are properly coordinated with the central controller, maintaining system reliability despite distributed access.
Solution Approach 2:
The session state acts as an intermediary data structure that bridges the central controller and mobile device. This session state contains the complete operational context including instrument parameters, diagnostic workflow state, and user interactions. By mediating all control operations through this shared session state, the system ensures consistent coordination between the central controller and remote mobile access points.
3Ease of operation
If multiple access points (central console and mobile device) are enabled simultaneously, then operational flexibility is maximized, but input/output conflicts may occur between platforms
Solution Approach 1:
The session state serves as a centralized intermediary that manages all input/output operations between the central controller and mobile device. When the session state is transferred to the mobile device, the central console's input capabilities are suspended for that session, preventing duplicate or conflicting inputs. The mobile device becomes the exclusive input interface for the duration of the remote session, while both platforms continue to access the same session state data, eliminating I/O conflicts while maintaining multi-location access.

AI summary
The session-state of a local user interface is transferred to a mobile device to permit an operator to execute remote tasks while maintaining interaction with a central controller. The session-state can be transferred between a user interface that is local to a central controller and a mobile computing device using indicia provided by the local user interface or the mobile computing device. The session is identified by the indicia, which is detected by a sensor in the local user interface or the mobile computing device to transfer session-state therebetween. Session-state can be advanced or influenced by, input at one platform at a time. Execution of control can continue regardless of the location of session-state interaction. The indicia used to transfer session-state between platforms can be provided in the form of a key or token that includes identifying information for the session.
