Millimeter Wave Radar Control for Image Processing Preliminary Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image processing devices perform unnecessary preliminary operations when power-saving mode is canceled due to accidental detection of a person, leading to inefficiencies in completing specific operations.
Innovation Solution
An electronic device equipped with a millimeter wave radar and a display, which displays an object that, when operated by an indicator, determines if the indicator's position is within a particular range of the object, and if so, transmits a preliminary operation command to the image processing device to initiate a preliminary operation, thereby shortening the time required to complete the specific operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the image processing device cancels power-saving mode upon detecting a person, then the device can perform image processing operations faster, but unnecessary preliminary operations are triggered when a person merely passes by
Solution Approach 1:
The system continuously monitors the position of the indicator relative to the operable object and uses this feedback to determine whether to cancel power-saving mode. The millimeter wave radar provides real-time position information, creating a closed-loop control system that adjusts the power mode based on actual user intent rather than merely detecting presence.
Solution Approach 2:
The patent replaces traditional mechanical or simple sensor-based detection systems with a millimeter wave radar system. This radar system uses electromagnetic waves to detect the position and movement of the indicator with high precision, enabling more accurate determination of user intent compared to simple presence detection.
2Productivity
If the image processing device starts preliminary operations earlier, then the specific operation completes faster, but the device performs unnecessary operations when triggered by accidental detection
Solution Approach 1:
The system performs preliminary actions (canceling power-saving mode) only when the indicator is detected within a specific range of the operable object, preparing the image processing device in advance to execute the specific operation faster. This preliminary action is conditionally triggered based on precise position detection.
Solution Approach 2:
The patent applies different detection thresholds and response behaviors based on the local condition of the indicator's position. When the indicator is within a specific range of the operable object, the system responds differently than when the indicator is merely present in the general vicinity, creating localized response zones with different qualities.
3Ease of manufacture
If the system uses simple presence detection to trigger preliminary operations, then the implementation is simpler, but accuracy in determining user intent deteriorates
Solution Approach 1:
The patent replaces simple presence detection systems with a millimeter wave radar system that uses electromagnetic wave reflection to detect the position and movement characteristics of the indicator. This substitution provides high-precision measurement of the indicator's position relative to the operable object, enabling accurate determination of user intent.
Solution Approach 2:
The system dynamically adjusts its detection and response behavior based on the real-time position and movement of the indicator. The millimeter wave radar continuously tracks the indicator's movement, and the system responds differently based on whether the indicator is stationary, moving toward the object, or moving away, capturing the dynamic nature of user interaction.

AI summary
A non-transitory computer-readable medium stores computer-readable instructions configured to, when executed by a processor of an electronic device, cause the electronic device to display on a screen of a display an object for receiving an instruction to cause the electronic device to perform a specific operation including controlling an image processing device, obtain a position of the object in the screen, obtain a position of the indicator based on output signals from a millimeter wave radar, determine whether the position of the indicator is within a particular range relative to the position of the object, and when determining that the position of the indicator is within the particular range, transmit to the image processing device a preliminary operation command instructing the image processing device to start a preliminary operation to shorten a time required to complete the specific operation.
