You state that your company manufactures and sells a suitcase that uses a non-removable lithium ion battery with a 39.52 Wh rating. You further explain that the battery powers the main functions of your suitcase, which include: a Bluetooth enabled lock; a built-in digital scale; a GPS location tracker; and USB ports to allow users to charge their portable electronic devices. Specifically, you seek confirmation of your understanding that this suitcase is authorized to be carried by passengers or crew if conforming to the portable electronic device provisions for passengers and crew aboard aircraft in § 17 5 .10( a)( 18) and electronic transmission requirements in 14 CFR part 91, § 91.21 . Your understanding of the requirement in§ 175.10(a)(18) is correct. According to the information in your email and the supplemental attachments provided, the suitcase meets the criteria for a portable electronic device prescribed in§ 175.1O(a)(l8). When carried by passengers or crew members for personal use, such suitcases that conform to the applicable provisions for portable electronic devices may be carried in either checked or carry-on baggage. You should be aware that an FAA Information for Operators (InFO) 17008: The Transportation Portable Electronic Devices (PED) in Checked Baggage has been published on this issue and can be found on FAA's website at www.faa.gov. The InFO advises that devices containing lithium batteries should be transported in carry-on baggage and not placed in checked baggage. When that is not possible, the devices should be completely powered down to the OFF position, protected from accidental activation, and packed so they are protected from damage. <<>> It is also important to note that the International Civil Aviation Organization (ICAO) during the twenty-sixth meeting of the Dangerous Goods Panel in Montreal, Canada on October 16 thru 27, 2017 adopted a new requirement that will require luggage equipped with a lithium battery to be carried as carry-on baggage, unless the battery is removed from the luggage. This new requirement will become effective in the January 2019 Edition of the ICAO Technical Instructions. This implementation will be applicable for all international transportation and on any air carriers that implement the ICAO or IA TA requirements as policy. You should always verify the air carrier policies prior to transportation. In addition to the HMR requirements, all applicable FAA requirements must be complied with, including those in 14 CFR, § 91.21 that address operation of portable electronic devices aboard aircraft. Information and guidance to assist with compliance of this requirement can be found in Advisory Circular (AC) 91.21 -lC, titled "Use of Portable Electronic Devices Aboard Aircraft." For additional information regarding the FAA requirements or if you seek an interpretation on whether your particular device meets electronic transmission requirements contained in 14 CFR § 91 .21 you may contact the FAA at the following address: Federal Aviation Administration Office of the Chief Counsel Regulations Division 800 Independence Avenue SW Washington, DC 20591 In addition to the transportation safety requirements pertaining to this device, there may be additional security requirements issued by the Transportation Security Administration. I hope this information is helpful. Please contact us if we can be of further assistance. Sincerely, - ~.- /' I I I , 1'-1· / '--!--'---· ---·· . I ./ ,:;"' I. Duane A.

The primary use of the battery in the suitcase is to power the main functions of our suitcase, which include a Bluetooth-enabled lock, a built-in digital scale, and 3G + GPS location tracking. As a secondary function of the battery, USB ports are provided to allow users to charge their portable electronic devices. We would like to request a letter of interpretation in regard to the inclusion of the Lithium-Ion battery. It is our understanding that our product complies with 49 CFR §175.10.18 due to the fact that: 1) our battery is "installed"; 2) is "of a type proven to meet the requirements of each test in the UN Manual of Tests and Criteria, Part Ill, Sub-section 38.3"; and 3) has a Watt-hour rating of 39.52 Wh. For reference, please find enclosed the UN38.3 test results and the Material Safety Data Sheet we use when shipping our product. To provide additional context around the design of our product, the battery in our carry- on suitcase is not removable, and the housing has been designed for maximum safety. In addition to the images included in the UN38.3 test results, see Exhibit A, which shows the location of the battery housing within the suitcase shell. See Exhibit B for a more detailed layout of how the battery housing design. See Exhibit C for additional information on the flame retardant materials used in the housing. Finally, it is our understanding that our product complies with FAA Advisory Circular (AC) 91.21-1C dated 5/7/2015 (specifically Section 8) due to having three different means of turning off electronic transmissions. First, users can turn the suitcase off manually via the on/off switch. Second, users can turn the suitcase off via the mobile application that connects to the suitcase. Finally, we have developed algorithms and Bluesmart Inc. 729 Minna St San Francisco, CA 94103 bluesmart.com <<>> o0o bluesmart 0 conducted tests to ensure the automatic shutdown of electronic transmissions upon flight takeoff. See Exhibit D for a brief memo that explains our methodology and results. We request a letter of interpretation so that we may confirm the compliance of our product with current regulations. Should you require further information to make your interpretation, please do not hesitate to contact us. Thank you in advance for your response.

A real flight case study is presented. I. INTRODUCTION The carry-on developed by Bluesmart (C0-01), is different from other wireless communication devices i.e. cellular phones, in the main fact that the cellular network is used at intervals, rather than, being constantly connected and sending-receiving information. To assure that the C0-01 is safe and does not interfere with any airplane communication and/or navigation instruments we develop a set of algorithms and rules that prevent the C0-01 to broadcast data or connect to the network while the aircraft is in flight. For the purpose of this document we will use the following definition of in-flight: "Any time from the moment all the external doors of an aircraft are closed following embarkation until the moment when any such door is opened for disembarkation[ ... ]". 1 Next we will present the sensors used and its characteristics. Then we described the process "Crosscheck" used to inhibit wireless communication while flying. Finally an example of a real flight is shown with the automatic detections performed with the computer onboard the luggage. II. SENSORS A set of sensors are used to identify the different parts of the flight. A 3-axis accelerometer, a barometer, a thermometer and a clock are embedded in the C0-01. Next we present the Barometer. A. Barometer The barometer, an IC used to measure pressure, with this data altitude can be computed. The barometer is heavily affected by noise, bias and drift. Sample data for a static case is shown in fig. 2. To reduce the effect of the noise an Infinite Impulse Response filter is used to obtain a better measurement. A comparison between this two values are shown in fig. 2. The barometer will be used in two scenarios. The first scenario is to assure that whenever the aircraft closes the doors the cellular functions (if being used) are immediately terminated, and disabled. In the second scenario, will determine if the movement in the aircraft is ascending or descending. B. Accelerometer The second sensor available is a three axis accelerometer. With this sensor the acceleration in three axis of the C0-0 I can be meassured. This sensor as well is very noise and a filter is used to obtain a pristine value. A sample filtered data is shown in fig. 3. We calibrate the accelerometer before we use it. In the next section we present and discuss the "crosscheck". <<>> 27590 1 11 27585 II 27580 G 27575 l 0 >> 30 ,.. ' -20 - I 6 Time [Hr] 8 Fig. 3. Accelerometer measurements 10 12 to detect the different e.dges on the curve. With this curves and comparing to the patterns of the aircraft we identify if the aircraft is on the air or not. The aircraft is identified as being in flights after the accelerometer detect the increase in the acceleration during take off followed by the pressure drop due to the climbing. Once the acceleration is detected the communications are inhibited to prevent the wireless communications to go off during takeoff. The The main drawback of this method is that will fail to prevent wireless emissions from the moment the door close to the moment where the take off run stars. To prevent wireless communication in this periods of time we use a background check. The Background check is used to sample the barometer and intervals to verify that the door has not been close. To identify the door close an abrupt change in the pressure output will occur. When this jump occurs the communications are inhibited as to prevent wireless communications. Once the flag of door-close is set the communications are inhibited and the crosscheck process continues as stated above. A plot showing an example of real door close is shown in fig. 4. The algorithms discussed above are implemented in the embedded computer inside the C0-01. These algorithms are constantly running in the background to assure that the crosscheck can function regardless of the user intervention and travel schedule. The algorithms are implemented to run on real time, hence the data is being discarded as soon as is processed to protect the users privacy. For the purpose of debug some C0-01 where modified as to record the entire data and different flight moments identifications. A sample trial from a real flight is shown in fig. 5. The plot is for a 10:00 Hr flight. There are two zones clearly marked. In blue, are the areas that represent the aircraft on the ground with the door open. In red, from door close till door open. These sections where identified with the crosscheck algorithm automatically. IV. CONCLUSIONS First we presented the sensors incorporated in the Carry-on developed by Bluesmart. Then, the different algorithms used to assure that no wireless communications are performed during flight were introduced. Finally, sample data from a real flight where shown. From the data shown is clear that the algorithm presented in this brief document clearly can capture the flight of the aircraft. With this algorithms the wireless communications are effectively inhibited during the flight of the aircraft. This assure that the Carry-on is safe to be carry on any aircraft. <<>> 27565 27560 u 0 >> ## Provenance - Official: Yes - Source: - Source ID: `phmsa` - SHA-256: `73de2c914334df2ac06328f217e548f2b74d9e63f4f84477ced8737e0d820672` - Retrieved: 2026-08-20T00:59:31.977Z - Exported: 2026-08-24T05:09:41.962Z - Document slug: `phmsa-interpretation-16-0124` ### Source metadata ```json { "materialSubtype": "interpretation", "interpretationArea": "hazardous_materials", "representation": "full_text_from_official_pdf", "companies": [ "Bluesmart, Inc" ], "individuals": [ "Mr. Brian Chen" ], "refIds": [ "16-0124" ], "catalogDates": [ "2018-03-06" ], "catalogParts": [ 175 ], "catalogRowCount": 1, "sourceRecordUrls": [ "https://www.phmsa.dot.gov/node/70326" ], "linkedAttachmentUrls": [], "unavailableResponseUrls": [], "duplicateRepresentationUrls": [], "citedSections": [ "175.10", "175.10(a)(18)", "175.1O(a)(l8)", "178.230", "178.195", "178.564", "178.560", "178.443", "178.430", "178.347", "178.640", "178.581", "178.551", "178.548", "178.446", "178.435", "178.232", "178.220", "178.172", "178.56", "178.512", "178.393", "178.336", "178.543", "178.521", "178.410", "178.192" ], "catalogPageUrls": [ "https://www.phmsa.dot.gov/regulations/title49/section/17510" ], "pdfUrls": [ "https://www.phmsa.dot.gov/sites/phmsa.dot.gov/files/docs/standards-rulemaking/hazmat/interpretations/57436/160124.pdf" ], "representations": [ { "viewUrl": "https://www.phmsa.dot.gov/sites/phmsa.dot.gov/files/docs/standards-rulemaking/hazmat/interpretations/57436/160124.pdf", "detailUrl": null, "detailHtmlPath": null, "pdfUrl": "https://www.phmsa.dot.gov/sites/phmsa.dot.gov/files/docs/standards-rulemaking/hazmat/interpretations/57436/160124.pdf", "pdfArtifactPath": "data/sources/phmsa-interpretations/16-0124-d060dd1c4b.pdf", "pdfArtifactSha256": "b710e63a000e2922a38dbb453be6eb2957d06f193af852a704833e5d12f07782", "extractedTextPath": "data/sources/phmsa-interpretations/16-0124-d060dd1c4b.v2.txt", "extractedTextSha256": "3efc40cce3d44dc9a49778f646f6499c3da08a614fea9f6ba8cea890a4b7f021", "pageCount": 29, "extractionVersion": 2 } ], "caveat": "Interpretations apply regulations to the facts presented and do not create independently enforceable requirements.", "jurisdiction": "US" } ```
