Abstract: The present disclosure provides electrosurgical apparatus and methods configured to separate two dissimilar materials, such as two different layers of biological tissue. The present disclosure also provides electrosurgical electrodes and electrosurgical apparatus and methods including same.

Abstract: A method for separating at least two dissimilar materials includes providing an electrode having a contact surface, placing the contact surface in contact with at least one material of the at least two dissimilar materials; and sliding the contact surface across and in contact with the at least one material of the at least two dissimilar materials while applying electrosurgical currents via the contact surface to thereby separate the at least two dissimilar materials.

Abstract: A method for treating surface tissue of a patient includes: providing an electrode having a contact surface, wherein the contact surface has a curved profile; placing the contact surface in contact with surface tissue of the patient; and sliding the contact surface across and in contact with the surface tissue while applying electrosurgical currents to the surface tissue via the contact surface to thereby vaporize and ablate the surface tissue and form a treated band of the surface tissue.

Abstract: A wireless communication device having a display screen with a holographic overlay. The holographic overlay includes an image that is visible when the display screen is viewed at predetermined angles. The holographic overlay may provide additional surface on the wireless communication device for marking and advertising, and may also provide security by preventing unintended viewers from seeing characters on the display screen. In one embodiment, the display screen includes a character screen, a lens, and a holographic overlay.

Abstract: A communication terminal including a communication unit, a longitudinal antenna enclosed in a radome, and a pivot connecting the antenna to the unit for pivoting about an axis with an RF connection to the unit. The unit is in a box-shaped enclosure having a front face with a keypad and connected to a rear face by top and bottom faces, and two side faces. One of the unit front and rear faces is non-planar from top to bottom with the spacing between the front and rear faces varying from top to bottom. The spacing between the radome front and rear faces varies to substantially match the varied spacing between the unit front and rear faces so that the radome and unit front and rear faces define a uniform profile when the radome is adjacent one unit side face. The unit top face lies on one side of a first plane and at least one unit side face lies on one side of a second plane perpendicular to the first plane.
