Abstract: Embodiments of the disclosure include coatings comprising an oligomerized polyphenol layer. The oligomerized polyphenol layer can be used as an intermediate coated layer on a medical device that hydrogen bonds to a synthetic or natural polymer, which in turn can be used as a top coat or further associated with another coated layer. The multilayered coatings can provide properties such as hemocompatibility or lubricity. In other embodiments, the oligomerized polyphenol layer is used on a medical device as a hemostatic layer configured to contact blood and promote coagulation. The oligomerized polyphenol layer can also be used on the inner surface (e.g., inner diameter) of a medical device to prevent bacterial adherence. The oligomerized polyphenol layer can also be used on the surface of a in vitro diagnostic article, or a cell culture device to, promote adsorption of a biological molecule.

Abstract: Hat, helmet, and other headgear apparatus includes dry electrophysiological electrodes and, optionally, other physiological and/or environmental sensors to measure signals such as ECG from the head of a subject. Methods of use of such apparatus to provide fitness, health, or other measured or derived, estimated, or predicted metrics are also disclosed.

Abstract: According to one embodiment, an apparatus is disclosed. The apparatus includes an endoscopic clip placement tool and one or more marking clips attached to a specimen mass by the clip placement tool to mark a margin and orientation of the specimen mass. A specimen marking clip is also provided that is adapted to selectively attach to tissue inside of a patient and corresponding tissue that has been excised from the patient for analysis. Sutures may be associated with the clips to help ensure correct in vivo and ex vivo sample orientation. In vivo clips may remain in the patient's body if necessary.

Abstract: A retractor used in inner-oral surgery is provided that includes a maxilla portion configured to maintain a patient's mount in an open state. The retractor also includes a blade that maintains the position of the tongue so that surgical tools are not obstructed. The maxilla portion of one embodiment only extends a portion of the length of the blade.

Abstract: According to one embodiment, a device is disclosed. The device includes a nasal cannula having prongs to supply air and covers inserted over the prongs to prevent discomfort during use of the nasal cannula.

Abstract: A four-valve per cylinder engine has two intake valves, two exhaust valves and a centrally located fuel injector. Between each adjacent pair of valves is a valve bridge with a point of minimum separation between adjacent valves. In the present disclosure, the glow plug port is defined in the cylinder top at a location outboard of the minimum separation between adjacent and at a depth which is tangent to an edge of a fuel jet emanating the injector. By placing the glow plug farther outboard than found in the prior art, the glow plug contacts the fuel as it comes out of the injector and as it rebounds off a feature of the piston bowl.

Abstract: A vee-engine has left and right cylinder banks have valve configurations that are mirror images of each other. The exhaust valves and associated exhaust ports are situated more toward the rear of the engine than the intake valves in any particular cylinder. With all the exhaust valves nearer the rear of the engine, the overall exhaust manifold runner length between the ports and the turbocharger is reduced relative to an engine with offset cylinder banks where exhaust valves in one bank are located nearer the front of the engine than exhaust valves of the other bank.
