OVERVIEW

1.1 SMART SPACE
ZeroKey Smart Space is an indoor positioning system that is capable of real- time positional tracking in three-dimensional space. The system is composed of multiple clip-on mobile units and fixed anchor units. The mobile units are designed to be worn or attached to people or equipment that can move about within the defined workspace. The anchor units are fixed in place and are used to assist in the determination of the mobile unit’s position. The mobile and anchor units exchange various signals, radiofrequency and ultrasonic pulses, and then use the collected information to determine the mobile unit’s position in 3D.

1.2 SAFE SPACE
ZeroKey Safe Space is an adaptation of the Smart Space system and is used to detect the proximity of two or more users to one another. The system is composed of multiple clip-on mobile units and specialized software to coordinate the proximity detection operation. The mobile units are designed to be worn or attached to people that can move about within the defined workspace. Each user’s device detects and alerts the wearer to the proximity of another user and records each instance of close contact infractions. The mobile units exchange various signals, radiofrequency and ultrasonic pulses, and then use the gathered information to determine the mobile unit’s distance to one another.

OPERATION

3.1 SAFE SPACE CONFIGURATION In Safe Space, the Mobile unit performs proximity detection for contact tracing purposes and to encourage social distancing. It does not perform full 3D positioning in this mode. The Mobile unit can be connected to a power source via a USB-C cable. This charges the unit but also acts as the method of powering the unit on. When disconnected from the USB-C connection the unit will remain powered on as long as there is sufficient charge. There is no user-facing method to power off the unit, as it is intended to be always-on. In regular operation, the user clips the Mobile unit to their clothing or equipment in an outward-facing manner. The user then goes about their standard day-to-day activities. Whenever the Mobile unit is within the Radio range of another Mobile, it will record this interaction as a low- accuracy event. Whenever the Mobile unit is within the ultrasonic range of another Mobile (default set to 4m), it will record this interaction with the specific range as a high-accuracy event. Whenever the Mobile unit is within alerting range of another Mobile (default set to 2m), it will not only record the interaction but also trigger the physical alerts. The physical alerts consist of a motor providing vibratory feedback (in a short-short-long pattern), a beeper producing an audible beep, and a white alert indicator LED on the top of the Mobile unit. When the user remains within alerting range of any other Mobiles, the alerts will repeatedly trigger to warn the user of their proximity to another user until they move apart. When alerts occur on one Mobile, it is aware of which other Mobile triggered them. For extra redundancy and to ensure that the Mobiles both remain in sync, the first Mobile will inform the other Mobile wirelessly to trigger their own alerts. When a user carrying a Mobile is within the Radio range of an (optional) Gateway device, the Mobile will proceed to dump all interaction data stored onboard wirelessly to the Gateway. This allows a server to take the data and display it in any fashion. As stated above, all recorded interactions at all distances will be recorded, not just those triggering alerts. This provides much more opportunity for data analysis, and to expand search distances when performing contact tracing. The Mobile has an RGB LED for status indication and each color operates independently. It blinks green every 5 seconds to indicate it is alive and active. It blinks red every 5 seconds to indicate a low battery state has occurred or that it is currently charging. The red LED will stop blinking once it has reached sufficient charge. When put into firmware update mode the blue LED turns on, and it blinks blue while performing the firmware update. Lastly, the Mobile goes enter deep sleep if it picks up no other ZeroKey radioactivity for 2 consecutive minutes. This only occurs when the Mobile is taken off-site or away from all other ZeroKey hardware. Once in this mode, the Mobile will wake up every 30 seconds to determine whether to resume normal activity. During the 30 second sleep time, the status RGB LEDs will be disabled but will operate once each time the Mobile wakes up.

3.2 SMART SPACE CONFIGURATION

In Smart Space, the Mobile unit performs full 3D positioning utilizing the installed infrastructure of ZeroKey Anchors, Gateways, and Repeaters. The Mobile unit can be connected to a power source via a USB-C cable. This charges the unit but also acts as the method of powering the unit. When disconnected from the USB-C connection the unit will remain powered on as long as there is sufficient charge. There is no user-facing method to power off the unit, as it is intended to be always-on. In regular operation, the user clips the Mobile unit to their clothing or equipment in an outward-facing manner. The user then goes about their standard day-to-day activities. As the user moves around, the Mobile will be interacting with nearby Anchor units to resolve its position in 3D space. The resulting positions will be broadcast wirelessly via the Gateway and Repeater hardware so that they can report to a central server. The server can use these positions in real-time to drive a dashboard, record position history, trigger proximity or zone-based alerts, and perform other data analyses. Alert Zones can be defined on the dashboard and server to indicate areas that users should not enter. When a user enters one of these zones an alert packet will be transmitted through the system out to the relevant Mobile. When the Mobile receives this alert packet, it will trigger the physical alerts on board to warn the user. The physical alerts consist of a motor providing vibratory feedback (in a short-short-long pattern), a beeper producing an audible beep, and a white alert indicator LED on the top of the Mobile unit. Until the user leaves the Alert Zone, the alerts will repeatedly trigger. The Mobile has an RGB LED for status indication and each color operates independently. It blinks green every 5 seconds to indicate it is alive and active. It blinks red every 5 seconds to indicate a low battery state has occurred or that it is currently charging. The red LED will stop blinking once it has reached sufficient charge. When put into firmware update mode the blue LED turns on, and it blinks blue while performing the firmware update.
