Motion-Triggered Wake Signal for Portable Transceiver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Personal assistant applications on stationary computers, such as laptops and desktops, cannot receive voice commands from portable transceiver units when the host computer is in a low-power sleep mode, preventing remote access and interaction.
Innovation Solution
A portable transceiver unit with a microphone for voice command input, a wireless transceiver for communication with the host computer, and a motion sensor to detect predetermined motion patterns, which triggers a wake signal to awaken the host computer, allowing voice commands to be processed and responses to be transmitted back.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the host computer is in low-power sleep mode to conserve energy, then energy consumption is reduced, but the computer cannot receive voice commands from portable transceiver units
Solution Approach 1:
The system performs preliminary action by sending a wake signal before the actual voice command interaction. The portable transceiver unit detects motion patterns and proactively transmits a wake signal to the host computer, preparing the system in advance for the upcoming voice command session. This ensures the computer is fully operational and ready to receive commands before the user actually issues them.
Solution Approach 2:
The portable transceiver unit acts as an intermediary between the user and the host computer. It detects motion patterns, transmits wake signals, and relays voice commands to the computer. This intermediary device enables remote interaction without requiring the computer to continuously monitor for commands, thus maintaining energy efficiency while enabling access.
2Ease of operation
If the host computer remains awake to receive voice commands continuously, then remote access is enabled, but energy consumption increases
Solution Approach 1:
Instead of continuous operation, the system uses periodic action triggered by specific events. The host computer transitions between sleep and active states based on periodic wake signals from the portable transceiver unit. This event-driven approach allows the computer to remain in low-power mode during extended periods while still being accessible when needed.
Solution Approach 2:
The portable transceiver unit provides self-service functionality by autonomously detecting motion patterns and initiating wake signals without requiring computer intervention. The system serves itself by automatically transitioning from sleep mode when motion is detected, eliminating the need for continuous monitoring by the computer.
3Adaptability or versatility
If motion sensors and wake signal functionality are added to enable remote access, then interaction capability is improved, but device complexity increases
Solution Approach 1:
The portable transceiver unit is designed with multi-functionality, serving as both a wireless audio device and a remote control interface. The motion sensor and wake signal capabilities are integrated into an existing portable device that users already carry, rather than requiring a dedicated remote control system. This universal approach adds remote access functionality without requiring entirely new devices.

AI summary
A method includes, with a portable, wireless transceiver, detecting a predetermined motion pattern of the transceiver; and in response to detecting the predetermined motion pattern of the transceiver, transmitting a wireless wake signal from the portable transceiver to a sleeping computer. A corresponding portable transceiver unit includes: a microphone to receive spoken voice commands from a user; a wireless transceiver to wirelessly communicate with a separate computer; and a motion sensor to detect a predetermined motion pattern at the portable transceiver unit. The wireless transceiver, in response to the motion sensor detecting the predetermined motion pattern of the transceiver, wirelessly transmits a wake signal to the computer.
