Assistive technology (AT) has the ability to improve the standard of living of those with disabilities, however, it can often be abandoned for aesthetic or stigmatizing reasons. Garment-based AT offers novel opportunities to address these issues as it can stay with the user to continuously monitor and convey relevant information, is non-invasive, and can provide aesthetically pleasing alternatives. In an effort to overcome traditional AT and wearable computing challenges including, cumbersome hardware constraints and social acceptability, we present Flutter, a fashion-oriented wearable AT. Flutter seamlessly embeds low-profile networked sensing, computation, and actuation to facilitate sensory augmentation for those with hearing loss. The miniaturized distributed hardware enables both textile integration and new methods to pair fashion with function, as embellishments are functionally leveraged to complement technology integration. Finally, we discuss future applications and broader implications of using such computationally-enabled textile wearables to support sensory augmentation beyond the realm of AT.

Flutter is an aeroelastic phenomenon that occurs in flexible bodies with relatively flat shapes, such as airplane wings and bridge decks. It involves oscillations with amplitudes that grow in time and can result in catastrophic structural failure. In its detail, flutter in practically all cases involves nonlinear aerodynamics. It is characteristic of flutter as a typical self-excited oscillation that, by means of its deflections and their time derivatives, a structural system taps off energy from the wind flow. This chapter considers two-dimensional (2-D) bridge deck behavior in smooth flow and briefly reviews the expression for the aerodynamic lift and moment acting on airfoils. It introduces the aerodynamic lift, drag and moment acting on bridge decks. The chapter reviews the solution of the flutter equations for bridges and discusses the bridge response to turbulent wind in the presence of aeroelastic effects.

A small mechanical device that incorporates a high-density ball bearing. Expiratory airflow moves the ball bearing producing both positive expiratory pressure (PEP) and high frequency oscillations of air within the airways.

Flutter is a MIDI Tone Poem realised entirely using Open Source software and recycled hardware. This is a testcard piece designed to demonstrate the capabilities of Rosegarden and Ardour using standard soundfonts and a couple of custom voices on my external D10. It is a structured instrumental piece based on the seed theme of f+f--f+f.

The patient’s medical history was significant for chronic obstructive lung disease, obstructive sleep apnea, type II diabetes mellitus, hypertension, hyperlipidemia, and major depressive disorder. The patient denied palpitations or light-headedness in the postoperative period. The patient reported a history of intermittent dizziness and falls over the preceding months. A telemetry strip that prompted the referral is shown in Figure 1. On examination, the patient was in no apparent distress. Her heart rate was regular without murmurs or gallops. Auscultation of lungs revealed normal breath sounds. She had a resting tremor in her right hand. There was no rigidity in any extremities, and the rest of the physical examination findings were normal. She was admitted to the cardiology service for management of new-onset atrial flutter. Serum chemistries (including potassium and magnesium) and complete blood cell count were within normal limits. A 12-lead electrocardiogram (ECG) was performed on arrival to the telemetry unit. It was determined that the ECG demonstrated artifactual waves, most prominent in the limb leads (Figure 2). It was determined that she had pseudoatrial flutter waves and she was subsequently discharged with an event monitor to determine the underlying cause of her falls.

<h3>To the Editor:</h3> —I wish to comment on the patient with diaphragmatic flutter described by Dr. Wallie L. Craddock in the August 4 issue ofThe Journal, page 1315. To add to his list of hospitalizations, he was in the Massillon, Ohio, State Hospital in the latter half of 1947 or early half of 1948, and known as John Allen. He had been committed following disturbed behavior while under observation for a "heart attack" in a Warren, Ohio, hospital. He claimed to be a retired merchant seaman, and he was quite interested in flowers and working in the greenhouse. The spring of this year he was in Chicago State Hospital. I would like to raise the question of whether his attacks are a matter of malingering as some physicians are inclined to assume. My conjecture is that they represent hysteria and that the flutter is a diaphragmatic equivalent of a
