Abstract: A handheld device includes a position sensor for sensing movement of the device's display screen relative to another object. A user of the device is able to vertically or horizontally move an image within the display screen by moving or positioning the device in space. An image can also be zoomed in or out by bringing the device and display screen closer to or farther from the user. The user can switch between a motion mode of panning and zooming or a non-motion mode where moving the device does not cause the image on the display screen to move. This allows the motion mode to be used with traditional forms of image manipulation and item selection using a pointer and “click” button. Function, sensitivity, calibration and other options for configuring controls and motion sensing are provided so that the translation of a motion of the device to a manipulation of the image on the screen can be modified to suit different user desires, or different applications or functions.

Abstract: The present invention relates to a method of providing nearly constant pressure during operation of a device incorporating a pressurized container and more particularly pre-ignition lubrication mechanisms for internal combustion engines, pressurized pre-combustion oiling mechanism for use with internal combustion engines, pressurized water or other fluid tanks, and pressurized fluid and other pressurized material dispensers. The present invention provides an accumulator tank containing either air or an easily condensed gas. The pressurized oil causes the air or gas in the bag to become compressed, causing a decrease in occupied volume in proportion to the pressure induced by the oil to allow the oil to occupy a suitable portion of the tank. In the preferred embodiment of the invention, the pressurized oil would cause the easily condensed gas to undergo a phase change and liquify.

Abstract: The present invention relates to pre-ignition lubrication mechanisms for internal combustion engines, and more particularly to a pressurized pre-combustion oiling mechanism for use with internal combustion engines. The present invention provides an accumulator tank containing either air or an easily condensible gas. The pressurized oil causes the air or gas in the bag to become compressed, causing a decrease in occupied volume in proportion to the pressure induced by the oil to allow the oil to occupy a suitable portion of the tank. In the preferred embodiment of the invention, the pressurized oil would cause the condensible gas to undergo a phase change and liquify. Conventional valving known in the state of the art is provided to allow the accumulated pressurized oil to be used prior to a subsequent engine startup, and conventional electronic control systems are provided to engage and disengage the aforementioned valves for a proper pre-ignition lubrication sequence.

Abstract: A conduit coating which is made by covering a surface thereof with a polymeric material which may include an additive made of bacteriostatic, bacteriocidal, fungicidal, fungistatic or mildew-suppressing material. The coating material may be cross-linked using radiation exposure to improve the high temperature characteristics of the conduit.

Abstract: In general, the invention comprises a device capable of emitting either acoustic or electromagnetic radiant energy. The device has at least one reflector with a smooth concave surface which reflects the energy emitted from the transducing element. The device also has at least two transducing elements for producing this energy. The shape of this reflector surface is preferably defined by either an ellipse or a parabola that is rotated about an axis of revolution, for any angular distance between zero and one complete revolution. The shape of this reflector surface can also be preferably defined by the coincident surfaces of revolution of an ellipse and a parabola that are rotated about a common axis of revolution.

Abstract: The invention comprises a device capable of emitting either acoustic or electromagnetic radiant energy. The device has at least one movable transducing element for producing this energy, and at least one reflector with a smooth concave surface which reflects the energy emitted from the transducing element. The shape of the reflector surface is preferably defined by either a rotated ellipse or a rotated parabola. A reflector surface of either shape is characterized by a continuum of distinct focal points that define a focal curve, such that each distinct focal point of the continuum is a unique focal point of each ellipse or parabola in the continuum forming the reflector surface. The radius of curvature of the parabolic surface of revolution can be extended up to an infinite length, causing the focal curve to appear as a straight line.

Abstract: An electrostatically clad conduit innerduct liner and method for making the innerduct are disclosed, The process includes, heating the innerduct to a temperature less than melting point of the innerduct or a powder to be coated on the inner surface of the innderduct, The powder to be coated is electrically charged and applied to the innerduct by spraying from a nozzle having a different polarity than the innerduct to provide a substantially uniform coating.

Abstract: In general, the invention comprises a device capable of emitting either acoustic or electromagnetic radiant energy. The device has at least two transducing elements for producing this energy, and at least one reflector which reflects the energy emitted from the transducing elements. The shape of the reflector surface is defined by both an ellipse and a parabola that are rotated coincidentally about a common axis of revolution (hereinafter referred to as a "para-elliptic" reflector surface), formed by coincidentally rotating, for up to one complete revolution, a section of both geometric shapes about an common axis of revolution that lies in the plane of both geometric shapes. The resulting "para-elliptic" reflector surface will be characterized by two sets of distinct focal points defining two focal curves. Focused energy will be redirected as if emanating from each focal region, causing each focal region to appear as a virtual source of the energy.
