Abstract: A patient securing overlay includes a sheet of fabric configured to support a patient's torso on a surgical table. The sheet of fabric includes friction enhancing elements applied to at least a portion of an upper surface. The sheet of fabric is attached near its side edges to two or more side flaps that extend laterally outward from the side edges of the sheet of fabric. Each of the side flaps is attached to the surgical table at two or more attachment points. A distance between adjacent attachment points is greater than a distance between an attachment point and the sheet of fabric in order to naturally create a favorable retaining force vector angle of less than 45° between the attachment point and the sheet of fabric.

Abstract: A touch screen keyboard is dynamically customizable to modify the active regions of one or more keys in the keyboard to adapt the keyboard to a user's unique physiology. The active regions may be modified in response to monitoring user input directed to the keys in the keyboard so that the keyboard automatically adapts to the user's physiology. In addition, while the locations and/or sizes of the active regions may be modified to adapt to a user's physiology, in some instances the shapes of the active regions may also be distorted such that the resulting active regions are irregular in nature.
