Abstract: An imaging device may include a first illumination port to output first light having a first illumination distribution at a target to illuminate the target, a second illumination port to output second light having a second illumination distribution at the target to illuminate the target, the second illumination distribution being substantially similar to the first illumination distribution at the target, the second illumination port being spaced apart from the first illumination port, the first and second illumination distributions being simultaneously provided to the target and overlapping at the target. The illumination from the first and second ports may be matched to a same aspect ratio and field of view coverage as the imaging field of view.

Abstract: A helmet includes a shell, a flexible frame having an inner surface and an outer surface attached to the inner surface of the shell, a pad having an inner surface and an outer surface attached to the inner surface of the shell and the inner surface of the flexible frame, and a slide-facilitating member attached to the inner surface of the pad. In virtue of the slide-facilitating member, the shell and the flexible frame can slide with respect to a user's head wearing it when receiving incoming impact, so that the helmet can absorb and convert energy of the incoming impact force into other forms of energy, thereby enhancing protection to the user's head.

Abstract: An exhaust gas aftertreatment system for a diesel-engined vehicle, which system comprising a NOx Storage Catalyst (NSC) followed in a downstream direction by a Catalysed Soot Filter (CSF), wherein the CSF comprises an oxidative catalyst comprising a palladium-rich weight ratio of platinum and palladium.

Abstract: The present disclosure is directed to arthroscopic visualization systems and methods. The visualization system can include a camera with a fluid inflow path, wherein a proximal end of the camera is configured to fluidly connect a fluid reservoir to the fluid inflow path. The system can also include a cannula with a lumen, wherein the lumen is configured to be fluidly connected to the fluid inflow path at a distal end of the camera. In addition, the system can also include a scope, wherein the scope is configured to be connected to the distal end of the camera and a portion of the scope is configured to be inserted into the lumen of the cannula.

Abstract: A helmet manufacturing method involves: producing a shell and a protector, the shell having two opposing cheek-protecting portions, the protector having a jaw-protecting portion and a neck-protecting portion connected to the jaw-protecting portion; putting the shell and the protector in a die such that bottom edges of the cheek-protecting portions of the shell connect to a top edge of the neck-protecting portion of the protector; introducing a foam material into the die, apply heat and pressure to the foam material such that the foam material expands and binds to an inner side of the shell and an inner side of the protector; and taking a helmet finished product out of the die. Therefore, both the jaw-protecting portion of the integrally-formed protector and the helmet finished product are reinforced.

Abstract: A goggle includes a goggle frame, a lens assembly including a lens mounted on the goggle frame, two reels rotatably mounted on the goggle frame on opposing left and right ends of the lens and a soft sheet mounted between the two reels and abutting the outer surface of the lens, and a control assembly that can be set on one of the two reels according to the dominant hand of the wearer. With this, once the soft sheet is dirty, the wearer operates the control assembly with his dominant hand, so that the control assembly drives the reel set to rotate. At this time, the driven reel will further drive the soft sheet to move laterally relative to the lens, and then roll up the dirty part, so that the soft sheet can always be kept clean in the part corresponding to the lens.

Abstract: A vessel-supportable flexible-elongate-element spooling system (100) for spooling a flexible elongate element (12). The system comprises a container (14) having an internal volume defined by a radially inner barrier (22), a radially outer barrier (24), and a base (26). A flexible-elongate-element feeder (18) feeds the flexible elongate element (12) towards the base (26) of the container (14). A flexible-elongate-element force applicator (20) applies a force to the flexible elongate element (12) to retain a curvature imparted to the flexible elongate element (12) on discharge from the flexible-elongate-element feeder (18). The curvature is at least in part defined by the inner barrier (22) and/or the outer barrier (24).

Abstract: A helmet includes a shell having a head-protecting portion and two opposing cheek-protecting portions, the two cheek-protecting portions extending downward, integrally from left and right ends of the head-protecting portion, respectively, a protector having a jaw-protecting portion and a neck-protecting portion, the neck-protecting portion extending backward, integrally from a back end of the jaw-protecting portion, wherein a top edge of the neck-protecting portion of the protector connects to bottom edges of the cheek-protecting portions of the shell, and a foam liner disposed on an inner side of the shell and on an inner side of the protector to couple the shell and the protector together. The helmet further comprises a support disposed within the protector and enclosed by the foam liner.

Abstract: A drape configured to cover a handheld imager for use in a medical procedure, the drape including a frame that is removably mountable to a front portion of an enclosure of the imager; and at least one light transmissive component mounted to the frame and recessed with respect to a front of the frame such that the at least one light transmissive component is positioned in front of at least one enclosure window of the imager when the frame is mounted to the front portion of the imager.

Abstract: A method of displaying fluorescence intensity in an image includes displaying a target reticle covering a region of the image; calculating a normalized fluorescence intensity within the target reticle; and displaying the normalized fluorescence intensity in a display region associated the target.
