Being well-hydrated also improves sleep quality, cognition, and mood. Smart Cap device on the top of a bottle can help you deeper understand and track the hydration issue relative to your body. 2.2 The purpose of the Cap The Smart Cap is invented to monitor a liquid volume over a long time period, and it would give GX’s customers great insight into how to improve the hydration of a body. 2.3 What the Cap is The Smart Cap is an integrated device that combines mechanical and electronic smart solutions. This is a rechargeable battery-operated device. The battery is powering the device for more than a week. A battery can be charged by a charging adaptor. There is a cable with a universal USB type A connector and a magnetic connector on the Gx Cap side. The Smart Cap measures the volume of a liquid in a bottle upon drinking action. The measured raw data is processed by the cap and sent via Bluetooth wireless communication to a mobile device. A mobile application can show this received and logged data in various combinations. The smart Cap has 21 multicolor LEDs used for various indications and notifications.

External conditions (outside world) include durability, sun protection, temperature, mechanical damage. Internal conditions (inside the bottle) include durability, temperature, mechanical damage and waterproof.

Designation of U.S. Agent for Service of Process Explanation: As required by section 2.911(d)(7), the applicant must designate a contact located in the United States for purposes of acting as the applicant’s agent for service of process, regardless of whether the applicant is a domestic or foreign entity. An applicant located in the United States may designate itself as the agent for service of process. In either scenario, the designation of the U.S. agent for service of process should be provided as an attachment to the equipment authorization application. The applicant must provide a written certification, which must: i.Be signed by both the applicant and designated agent for service of process, if the agent is different from the applicant. All signatures must be an actual signature/image or a secured electronic signature such as can be done with Acrobat. ii.Acknowledge the applicant’s consent and the designated agent’s obligation to accept service of process. iii.Provide a physical U.S. address and email for the designated agent. iv.Acknowledge the applicant’s acceptance to maintain an agent for no less than one year after the grantee has terminated all marketing and importation or the conclusion of any Commission-related proceeding involving the equipment. NOTE: The U.S. Agent for Service of Process should not be confused with the authorized agent used for signing the 731 form, other cover letters within the application, and agent who may interface with the TCB. We have provided two letters to follow. The first is intended for when the Designated Agent specified is separate from the Applicant. The second letter is for cases where the applicant is specifying they are both the Applicant and the Agent for Service of Process. Further Clarification provided from the FCC on February 14, 2023 via TCB Council. The Agent for Process of Service: •Should not be a TCB or affiliated with a TCB (e.g. could not be a person who works for a TCB or a company that owns or is owned by the TCB) unless conflict of interest/impartiality has been evaluated. See KDB 986446 Q12. •Agent can be Individual Entity or a Company Entity •Agent Entity must be located in US, US address/phone •Entity acting as Agent must report their FRN of this exists. •Agent letter does not have to be FCC ID specific, can be general Agent for Grantee For devices being marketed or for which marketing has ceased for less than 1 year, if the Agent for Process of Service changes, then for every TC Number the TCB must request the FCC to put application into Audit Mode and Agent Letter needs to be updated (superseded).

The minimum test separation distance is determined by the smallest distance from the antenna and radiating structures or outer surface of the device, according to the host form factor, exposure conditions and platform requirements, to any part of the body or extremity of a user or bystander (see 5) of section 4.1)." p. 2 of 3 SAR exclusion evaluation: 1. Max. (conducted) power: 1.9dBm 2. Antenna gain: 2.1dBi 3. EIRP = max. power + antenna gain = 1.9+2.1 = 4dBm = 2.5mW 4. Minimum distance from human body: 10mm = 0.01m FCC Test Limit For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] *·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. p. 3 of 3 Test Results Frequency FCC calculation FCC limit Verdict (MHz) 2440.0 [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] *·[√f(GHz)]=[2.5/10]*[ √2.4]= 0.38 ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR Pass Figure 1 Test Results 3.
