The Smart USBLite system combines the following FDA 510(k) previously cleared devices into a repackaged, smaller-sized, single, integrated unit: SmartEP (K904926), SmartScreener (K925648), SmartOAE (K964426), SmartTrOAE (K023859), SmartEP-ASSR (K031051), and Opti-Amp DC-Powered (K052060). The Smart USBLite is intended to be used by trained personnel in a hospital, nursery, clinic, audiologist's office or other appropriate setting. The anatomical sites of contact are: (1) The patient's scalp and possibly other body sites with the contact objects being electrodes that are capable of measuring bio-potentials (2) The patient's ear with the contact object being a sound delivery device eartip, headphone, ear probe, or ear cups.
Device Story
Smart USBLite is an integrated auditory evoked potential and otoacoustic emission system. It records physiological signals (AEP, OAE, ASSR) via electrodes and sound delivery transducers (ear probes/headphones). The device processes these inputs to measure response levels, latencies, and signal-to-noise ratios. It is used in clinical settings (hospitals, clinics, audiologist offices) by trained personnel. The system consolidates previously cleared IHS hardware into a single, portable unit with embedded pre-amplifier electronics. Output is displayed on a connected PC for clinician review to aid in diagnosing hearing disorders and estimating hearing thresholds. Benefits include improved portability and streamlined clinical workflow for auditory testing.

#### Technological Characteristics:
The Intelligent Hearing Systems (IHS) family of products is intended to be used for recording and analysis of human physiological data for the purpose of neurological diagnosis, screening, and treatment of sensory disorders. The Smart USBLite device referenced above is the latest in a series of systems of this type marketed by IHS. Other related devices comprising the IHS family of products include:
- 1) 510(k) #K904926 SmartEP Auditory Evoked Potential System
- 2) 510(k) #K904926 SmartScreener Automated Auditory Evoked Potential Screening System
- 3) 510(k) #K964426 SmartOAE Distortion-Product Otoacoustic Emissions System
4) 510(k) #K023859 - SmartTrOAE Transient Otoacoustic Emissions System
- 5) 510(k) #K031051 SmartEP-ASSR Auditory Steady-State Response System
6) 510(k) #K052060 - Opti-Amp DC-Powered Physiological Signal Amplifier System
The feature modifications described in this Special 510(k) are to incorporate a repackaged variation of the listed predicate devices combined into a smaller-sized single integrated unit, the Smart USBLite. The Smart USBLite device is identical to the predicate device(s) in its intended use and methodologies, which have not changed as a result of modifications to the general specifications of the device. The Smart USBLite device can be used to perform all four different kinds of tests provided by the listed predicate devices, namely: auditory evoked potentials (AEP), auditory evoked potential screening, distortionproduct otoacoustic emissions (DPOAE), transient otoacoustic emissions (TrOAE), and auditory steadystate response (ASSR) testing.
The modifications associated with this new Smart USBLite device are mostly to the physical layout and aesthetics of the device hardware only, and do not change the software in any significant way. The new device utilizes hardware variations primarily to enhance size-reduction and portability, while still performing the same hardware functions in essentially the same ways as the predicate devices. The Smart USBLite uses the same five software packages used by the five individual predicate devices (i.e., SmartEP, SmartScreener, SmartOAE, SmartIrOAE, and SmartEP-ASSR software). The software has remained essentially the same for the new device, with small variations to accommodate differences in hardware. The same functionality and user interfaces have remained. Together, these minor hardware and software changes implement the same functionality and perform the same intended uses as the predicate devices in a single integrated unit.
The Smart USBLite hardware is very similar in electronics design to the predicate device hardware, except that the electronics hardware has been repackaged into a single, smaller, stand-alone box. Unlike the predicate devices, there is no separate pre-amplifier unit connected to the patient in the Smart USBLite system. Instead, all of the pre-amplifier electronics have been embedded inside of the SmartUSBLite receiver unit. The same patient isolation methods are used.
Besides packaging, the other minor modifications to the Smart USBLite over the previous devices are the number of input/output channels, gain, and filter specifications/characteristics. A complete comparison between the Smart USBLite and the predicate devices is given in specifications Table 1.
Figures 1-2 give simplified block diagrams for the predicate devices system hardware and the new Smart USBLite system.
{2}------------------------------------------------
#### Safety and Effectiveness:
The Smart USBLite utilizes many of the same design principles, circuit designs, and operating principles as are used in the predicate devices. All of the modifications of the Smart USBLite device were designed in accordance with procedures that meet FDA QSR Design Control and ISO-13485:2003 specifications.
The Smart USBLite device will be evaluated and certified for both electromagnetic compatibility and electrical safety prior to release, by a certified National Recognized Test Laboratory (NRTL),
Washington Laboratories, Ltd. 7560 Lindbergh Dr. Gaithersburg, Maryland 20879,
which will conduct the appropriate EMI/EMC testing for medical equipment, to elements of the requirements of:
- . EN60601-1:1990: "Medical Electrical Equipment, Part I : General Requirements for Safety."

Image /page/9/Figure/0 description: This image is a block diagram of predicate device hardware. The diagram includes components such as electrodes, an ear probe, earphones/headphones, and a pre-amplifier labeled as (Opti-Amp DC-Powered). The pre-amplifier has an isolation of 400 Volts DC and 10 MegaOhms, and it connects to a desktop or laptop computer via a fiber optic cable and a predicate hardware receiver unit. The power supply is medical grade and operates at 120/240 Volts, providing +/-15 Volts DC and +5 Volts DC.
Figure 1: Block diagram of the predicate devices hardware system. This system uses an Opti-Amp pre-amplifier unit (refer to FDA 510(k) numbers K914876 and K052060) connected to the patient, which is powered by one of two schemes: 1) Two AA batteries housed internally (K914876), or 2) +15Volts taken from the hardware receiver unit and regulated using a high voltage isolation DC-DC converter (K052060).

1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
