Transmitter Device Status Broadcasting via Periodic Advertisements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems face difficulties in tracking device interactions and varying configurations over time, especially in environments with multiple devices, as they struggle to determine the operating state and user interactions with nearby devices dynamically.
Innovation Solution
A transmitter device coupled with a radio transmitter, processors, and data storage, which broadcasts device status information, including user configuration data and operating modes, using a series of advertisements that can be detected by mobile devices, allowing for the tracking of device interactions and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If device status information is broadcast continuously using radio transmitter, then mobile devices can automatically obtain and analyze device status information, but energy consumption increases and information overload occurs
Solution Approach 1:
The radio transmitter broadcasts device status information in periodic advertisement intervals rather than continuously. The system uses configurable broadcast intervals to balance information availability with energy conservation, transmitting status updates at regular periods instead of maintaining constant transmission.
Solution Approach 2:
The system filters and prioritizes device status information based on user relevance and device proximity. Mobile devices receive and process only the most relevant status information from nearby devices, reducing overall data transmission volume and energy consumption while maintaining information quality for end users.
2Adaptability or versatility
If multiple devices broadcast status information simultaneously, then comprehensive device tracking is achieved, but signal interference increases and detection difficulty rises
Solution Approach 1:
The system segments device status information into distinct advertisement packets with unique identifiers and type classifications. Each device's status information is packaged separately with metadata that enables mobile devices to filter and process relevant advertisements without being overwhelmed by simultaneous broadcasts from multiple devices.
Solution Approach 2:
The radio transmitter uses standardized advertisement protocols as intermediaries to mediate between multiple broadcasting devices and receiving mobile devices. These standardized formats enable systematic filtering, prioritization, and processing of advertisements, reducing detection difficulty even in environments with multiple simultaneous broadcasters.
3Measurement precision
If detailed device status information is transmitted, then complete device state monitoring is achieved, but data transmission time increases and bandwidth consumption rises
Solution Approach 1:
The system extracts and transmits only the essential device status information that is most relevant to user needs and device functionality. Rather than transmitting complete device state data, the system identifies and broadcasts key status parameters, reducing transmission time and bandwidth consumption while maintaining sufficient monitoring accuracy for practical applications.
4Use of energy by moving object
If radio transmitter broadcasts are restricted to short range, then energy consumption is reduced and interference is minimized, but device status information availability decreases
Solution Approach 1:
The radio transmitter dynamically adjusts its broadcast power level and range based on detected mobile device presence and signal conditions. When mobile devices are detected in proximity, the transmitter increases power to ensure reliable information delivery. When no devices are present or signal conditions are poor, the transmitter reduces power consumption while maintaining adequate coverage for nearby devices.

AI summary
Methods, systems, and apparatus, including computer programs encoded on computer storage medium for implementing the advertisement of device status information. In one aspect, device status information for the second device is obtained, where device status information includes data indicating a current operating mode of the second device or configuration data indicating a user-specified configuration of the second device. The stored radio transmitter identifier is accessed from the one or more data storage devices. A first advertisement that indicates the radio transmitter address and the radio transmitter identifier is generated. A second advertisement is generated that indicates the radio transmitter address and an encoding of the device status information for the second device. Using the radio transmitter, a series of advertisements that includes at least the first advertisement and the second advertisement is broadcasted.
