Abstract: An input device includes a control surface for a color correction system. The control surface includes a housing with an upwardly facing control panel. The control panel has a proximal edge which is nearest a user and a distal edge that is furthest from a user in normal use. The control panel includes a plurality of controls. The plurality of controls includes: a plurality of trackballs, wherein each trackball comprises a ball and a control ring, said ball cooperating with at least one encoder to generate a multi-dimensional control signal based on motion of the ball, and said control ring cooperating with at least one encoder to generate a one dimensional control signal based on the rotational motion of the ring, wherein the ball of said trackball is mounted concentrically with said control ring; a plurality of control buttons; and a plurality of knobs coupled to respective rotary encoders.

Abstract: A vehicle mechanism is provided. The vehicle mechanism may include a stationary member including a main portion provided with an offset surface region including a bearing-surface region having non-planar regions. The mechanism may also include a moveable member that may be configured to move with respect to the stationary member. The moveable member may include a mating-bearing-surface region that may be configured to engage the bearing-surface region of the stationary member. A coating may be provided on the main portion and the bearing-surface region. The coating on the main portion may have a first thickness and the coating on the bearing-surface region may have a second thickness. The second thickness may be least 20% greater than the first thickness.

Abstract: Described is a dynamic phantom. The phantom comprises a body having a front, a back, and an internal cavity between the front and the back, the body having a movable chest wall. The phantom also comprises a first motion mechanism that is actuated to move the chest wall to thereby move the front relative to the back of the body. The phantom also comprises a moveable organ member supported within the internal cavity that is caused to move relative to the body by a second motion mechanism. The phantom also comprises a drive source for driving the first and second motion mechanisms, wherein the first and second motion mechanisms move the chest wall and the moveable organ member to substantially represent their movement in a human body.

Abstract: An inflatable cushion adapted to be supported on a surgical table for use in supporting the knees and legs of a person during surgery. The cushion includes an inflatable bladder, which has top and bottom walls that are parallel to one another, and a side wall that is pleated such that the top and bottom walls remain generally parallel to one another when inflated. The cushion also includes a removable cover having an opening through which the bladder may be inserted and removed.

Abstract: An inflatable cushion for use in a method of supporting the knees and legs of a person during surgery includes an inflatable bladder that can move from a collapsed state to an expanded state. The method involves placing a patient on a surgical table, decompressing the patient's spine to a flat back/drop knee position, interposing the bladder between the table and the patient's knees and advancing the knees to a full prone position by inflating the bladder.

Abstract: An inflatable cushion for use in a system and method in supporting the knees and legs of a person during surgery included an inflatable bladder that can move from a collapsed state to an expanded state. A bladder port communicates with a source of inflating gas. The system includes the source of pressurized gas and a valve assembly to switchably control the inflation and deflation of the bladder. The bladder may have a removable cover extending around the bladder, and the bladder may have side pleats to assist in expanding with the cover having corresponding accordion folds. The method involves placing a patient on a surgical table, decompressing the patient's spine to a flat back/drop knee position, interposing the bladder between the table and the patient's knees and advancing the knees to a full prone position by inflating the bladder.
