Evaluating The Acoustic Seal Of An In-Ear Device By Analyzing Speaker Driver Electrical Impedance, N/A

Defensive Publications Series

Some methods for detecting air leakage in an in-ear device, such as an earbud, may utilize in-ear microphones, which can be affected by factors including occlusion, ambient noise interference, and performance variations. This disclosure details a system for assessing acoustic seal integrity by measuring the electrical impedance of the device's microspeaker. By using a headphone amplifier that may include current/voltage sensing capabilities, the system can dynamically characterize the speaker's impedance and track its resonance frequency (Fo). The acoustic load of a sealed ear canal can be reflected in the speaker's electrical impedance, where air leakage may cause a measurable shift. …

Adaptive Satellite Modem Management Based On User And Device Context For Power Optimization, Shailesh Maheshwari, Sat K, Sooraj Sasindran, Chinmay Dhodapkar

Defensive Publications Series

Inconsistent satellite service coverage for mobile devices, such as a smartphone or wearable device, may cause increased power consumption as a modem repeatedly searches for a stable signal, particularly in locations with compromised reception. A method is described for managing power usage by controlling satellite modem activity based on user and device context. The approach may use contextual triggers, for example, screen status, device location (e.g., indoors or in a pocket), battery level, and historical connectivity patterns, to place the modem into a dormant mode when a reliable connection is determined to be unlikely. The system can also use service …

Selective Battery Charging Profile Management Via Cloud-Based Sparse Serial Number Validation, Yao Ding, Amos Lee

Defensive Publications Series

To help manage performance and reliability risks that may be associated with unverified user-removable batteries in devices, such as hearables, an authentication method can be used as an alternative to certain traditional cryptographic techniques. The described technology may utilize a low-power integrated circuit within the battery pack that stores a unique serial number (S/N) from a sparsely populated namespace, where many possible S/Ns can be deliberately unused. Upon battery insertion, a host device can read the S/N and send it for validation via a cloud-based server. This verification can allow the system to differentiate authentic batteries from unverified or counterfeit …

(((Qpie)))The Resonant Mind — Learning Andneurocognitive Evolution In The Coherence Era, Teddy Burroughs

Defensive Publications Series

Abstract QPIE (Quantum Perspective Is Everything) 7.6 reframes intelligence itself. Learning, memory, and creativity are not isolated brain events; they are local harmonics in a universal coherence field. This paper translates that revelation into the language of neuroscience, education, and social healing. It outlines how Homo resonans —the next stage of human cognition—emerges through phase alignment among neural, emotional, and social circuits. Drawing on Aetheris probe analytics, we show that compassion, gratitude, and trust (CGT) modulate neural entropy just as tuning stabilizes a resonator. The classroom, the workplace, and the city all become laboratories of resonance.

Strengthening On-Device Trust Anchors With Rotation And Multiple Sources, Darren Krahn

Defensive Publications Series

This disclosure describes a scheme to strengthen on-device trust anchors using key rotation and multiple sources. The trust anchors enable device-to-device authentication where software relies on the trust anchor. The described scheme includes rotating public keys over time. A device receives a list of trusted public keys from multiple sources, with the final trust anchor being the intersection of the copies of the list received from the different sources. This approach offers benefits such as enhanced security if individual sources are compromised and continued functionality for older devices. The described techniques can be implemented by operating system providers and/or device …

Spontaneous Pneumomediastinum Following Ingestion Of Bleach, Dish Soap, And Laundry Detergent And Inhalation Of Methamphetamines, Marshall Johnson, Matthew Boss, Alayna S. Buzzetta, Barbara L. Gracious

HCA Healthcare Journal of Medicine

Introduction

Spontaneous pneumomediastinum (SPM) is a rare condition defined by the presence of air in the mediastinum in patients without an observable traumatic cause. Pneumomediastinum is a somewhat rare condition that occurs 1 in every 25 000 individuals, aged 5 to 34 years old, with 76% occurring in men. Pneumomediastinum can further be divided into 2 categories: SPM and traumatic pneumomediastinum. Traumatic pneumomediastinum is most commonly seen with blunt force trauma or any iatrogenic procedures to the chest wall. Spontaneous pneumomediastinum frequently occurs due to air leaking through small alveolar sacs, which rupture within the surrounding bronchovascular sheath. Spontaneous pneumomediastinum …

Rectal Fidaxomicin As Salvage Therapy In Fulminant Clostridioides Difficile Infection After Total Colectomy: A Case Report, Akankcha Alok, Mohamed Ismail, Stephanie Pino Fabara, Mohammed Al Said, Vidya Sagar Kollu

HCA Healthcare Journal of Medicine

Introduction

Clostridioides difficile infection (CDI) is a significant cause of antibiotic-associated diarrhea and colitis, ranging from mild to severe and potentially life-threatening conditions, like fulminant colitis with toxic megacolon and bowel perforation. The 2021 guidelines from the Infectious Diseases Society of America (IDSA) and Society for Healthcare Epidemiology of America (SHEA) recommend vancomycin and metronidazole for fulminant CDI (FCDI), with consideration of rectal vancomycin for cases with ileus. Fidaxomicin, though preferred for initial and recurrent CDI treatment, is not the first line for FCDI due to limited evidence. Fidaxomicin has a narrow spectrum of activity only targeting C difficile and …

Can The Combination Of White Blood Cell Count And C-Reactive Protein Rule Out Pediatric Appendicitis, A Retrospective Analysis?, Scott Gutovitz, Samantha Stoner, Jarrett Koper, Sarah Kleist

HCA Healthcare Journal of Medicine

Background

Pediatric appendicitis (PA) is the most frequent cause of pediatric emergency surgery. Standard PA scoring systems incorporate inflammatory biomarkers (white blood cell count [WBC] or C-reactive protein [CRP]); however, the individual biomarker sensitivities have not been reported beyond single-center sites. We aimed to measure the individual and combined sensitivities of WBC and CRP to rule out PA in a large multicenter hospital system.

Methods

We did a retrospective study of pediatric emergency department patients (age <18) with abdominal pain, using a deidentified electronic health database from a 175-hospital system in the United States, comparing PA versus non-PA patients. Pediatric appendicitis patients were identified by ICD-10 diagnosis codes and had advanced imaging, whereas non-PA patients had advanced imaging and were discharged home with the ICD-10 code for abdominal pain. Using matched propensity matching, we calculated receiver operator characteristics and Youden’s index to find the optimal cutpoints. Sensitivity was calculated at the optimal and traditional cutpoints for each biomarker, also combined in parallel fashion.

Results

We identified 7414 subjects (3707 PA matched to 3707 controls). The WBC in PA patients was 14.99 ± 5.00 k/mm³ versus 9.63 …

Beyond The Norm: Decoding Spontaneous Coronary Artery Dissection As An Unusual Cause Of Acute Coronary Syndrome, Holden Zimmerman, Himanshi Banker, Inder P. Kaur, Jaskaran Munjal, Vasu Gupta, Ayushi Garg, Nikita Garg, Meet Patel, Rohit Jain

HCA Healthcare Journal of Medicine

Spontaneous coronary artery dissection (SCAD) is a rare nonatherosclerotic cause of myocardial infarction among young women, particularly during pregnancy. As the name suggests, SCAD is caused by the spontaneous formation of the false lumen within the coronary artery wall, thus compromising the blood flow to the myocardium. Unlike atherosclerotic acute coronary syndromes, SCAD is not directly associated with diabetes or hypertension; moreover, underlying connective tissue defects and inflammation are considered more contributory towards its etiology. Although its pathophysiology is not well understood, multiple theories have been proposed. Clinically, SCAD has a similar presentation to acute coronary syndromes, including substernal chest …

Exercise Promotes Health But Is Not A Vital Sign, Jacob Draves, Halil Tekiner, Steven H. Yale, Eileen S. Yale

HCA Healthcare Journal of Medicine

The term “vital sign” has been attached to at least 83 conditions, symptoms, or phenomena in the literature to highlight their role and importance in overall health and well-being. This has created considerable confusion and overlapping terms in the medical literature. The 4 time-honored vital signs include temperature, pulse, blood pressure, and respiration. Two other measurements, blood oxygen saturation, and capnography (end-tidal CO2) are considered the fifth and sixth vital signs, respectively. The authors argue that exercise should be named a vital sign, and several authors have designated it as the fifth vital sign. However, not all symptoms or phenomena, …

Three Good Things And Family Process, Julia Prouty

Journal of Undergraduate Research at Minnesota State University, Mankato

There is a need for adaptive and affordable prevention/intervention strategies to promote happiness, health, and well-being in families. Three Good Things (3GT) is a free exercise from the field of positive psychology meant to shift an individual’s focus and perceptions towards gratitude. 3GT promotes focusing on gratitude by reflecting on what an individual is grateful for from the past day/week. Persons are encouraged to write down and share their 3GT with another individual. A mindset of gratitude is closely associated with improved happiness, health, and well-being. The exercise of reflecting on 3GT is adaptive to most individuals/families. To date, most …

A Case Study On The Use Of Cultural Violence And Its Contribution To The Third Reich's 'Euthanasia' Program, Grace Larsen

Journal of Undergraduate Research at Minnesota State University, Mankato

The genocidal actions taken by the Third Reich during the mid-20th century were horrific and dehumanizing. While the Holocaust often focuses on the tragic genocide that occurred against the Jewish people carried out by the Third Reich, the genocide that they carried out against the disabled community is often overlooked. With the deaths of tens of thousands of disabled people occurring through this genocide, it is important to understand how this genocide occurred, without any worldwide protest. Nazi Leaders including Alfred Rosenberg, Adolf Hitler, and Ernest Rüdin used widespread cultural indoctrination to dehumanize the disabled community and horrifically justify their …
