Abstract: Nonwoven resorbable pouches that at least partially enclose implantable medical devices and improved methods for producing the implantable medical device pouches are described. The nonwoven pouches may comprise one or more drugs. Implantable medical devices that are placed in the pouches prior to implantation are prevented from migrating from the site of implantation by tissue ingrowth into the pouch. Antibiotics may be incorporated into the pouches to prevent post-operative infections. The pouches may be formed in fewer steps than conventional pouches, and without polymer coatings. Nonwoven pouches can be formed in one step by dry spinning instead of using multiple processing steps. In embodiments, the nonwoven pouches are smoother on the inside than the outside to tightly fit the implantable medical devices internally while encouraging external tissue ingrowth.

Abstract: Many headset devices, such as virtual reality helmets, present visuals that respond to the user's motion, such that a rotation of the user's head causes the visual to be re-rendered from a correspondingly rotated perspective. The lag between the user's motion and the updated rendering from the new perspective may be perceivable even at high framerates, and may induce unpleasant feelings such as vertigo. Instead, headset devices may respond to detected motion by identifying a displacement of the physical location of the visual that causes it to maintain a physical position relative to a stationary reference point. The display is operatively coupled with a displacer, such as actuators or a projection adjustment, that are engaged to displace the display according to the identified displacement and maintain a physical location of the visual relative to the stationary reference point (e.g., until the visual is re-rendered from the updated perspective).
