Abstract:
The pages of a book being held at least partially open may be sequentially automatically turned over from one side of the book to the other by pivoting an elongated arm from one side of the book toward the other and turning over individual pages with a vacuum head pivoting relative to the elongated pivoted arm about a different pivot axis as the elongated arm moves to reduce undesirable forces on the individual book pages being turned over. The vacuum head may initially pivot to bend the edge of an individual page up away from the book, to aid in page separation, and then subsequently differently pivot to help peel the same page gently away from the vacuum head and flip it over onto the opposite side of the book. This may be assisted by moving frictional belts on the vacuum head.
Abstract:
A liquid pilot assembly for use in an outdoor fuel spill fire fighting trainer is provided. This assembly includes a spark plug igniter unit, a liquid fuel system, an air distribution system, a housing enclosing the components and a vaporization subassembly disposed within the housing for changing liquid fuel to vapor fuel.
Abstract:
A method and apparatus for measuring blood pressure and controlling the pressure of a pneumatic tourniquet at a desired level, either above the systolic blood pressure or at an absolute level.
Abstract:
Systems and methods are providing for endoscopically visualizing tissue within a patient. In one aspect, an endoscope comprises an elongate shaft having a distal end and a proximal end and a visualization section at the distal end of the shaft. The visualization section includes a proximal surface and an outer surface spaced apart from the proximal surface. At least one of the proximal surface or the outer surface of the visualization section has an average surface roughness less than about 50 nanometers RMS. The endoscope allows improved remote visualization while not interfering with the autofocus feature of a video capture system and not causing increased light reflectance and glare due to improved surface finish.
Abstract:
An optical coupler for mounting at a distal end of an optical imaging device includes a visualization section and an attachment section. At least one surface of the visualization section has a roughness that does not interfere with a video capture system of an optical imaging device. The optical coupler is sized and dimensioned for introduction into a region of the patient's heart for viewing a procedure, such as a heart valve repair or replacement procedure.

Abstract:
Clip on “flip-up” attachable auxiliary nose protection assembly adapted to clip onto a pair of eyeglasses or sunglasses and including a nose protection piece pivotally movable to a first position covering a persons nose and a second position uncovering a persons nose to protect the wearers nose from sunlight or to allow the wearer to modulate some sunlight exposure. The apparatus has two main parts, including a clip means which attaches to a pair of eyeglasses or sunglasses and a nose protection portion which is pivotally attached to the clip means. Preferably the nose protector and the clip means are manufactured from lightweight durable plastic and moldable metal. When the nose protection apparatus is attached to pair of eyeglasses or sunglasses the nose protection portion may be locked into a functional position or a position which is substantially parallel to the wearers nose and an inoperative position or a position which is substantially perpendicular to the wearers nose.
