Abstract: Disclosed is a device and method for externally perforating a well-bore casing. The perforating apparatus is attached to the outside of the casing itself and is conveyed along with the casing when it is inserted into the well bore. The perforation is accomplished using two groups of charges which are contained in protective pressure chambers which are arranged radially around the outside of the wellbore casing. The pressure chambers form longitudinally extending ribs which conveniently serve to center the casing within the well bore. One group of charges is aimed inward in order to perforate the casing. A second group is aimed outward in order to perforate the formation. In an alternative embodiment, only one group of bi-directional charges is provided.

Abstract: An interactive video window display system. A projector projects a visual image. A screen displays the visual image, wherein the projector projects the visual image onto a back side of the screen for presentation to a user on a front side of the screen, and wherein the screen is adjacent to a window. An illuminator illuminates an object on a front side of the window. A camera detects interaction of an illuminated object with the visual image, wherein the screen is at least partially transparent to light detectable by the camera, allowing the camera to detect the illuminated object through the screen. A computer system directs the projector to change the visual image in response to the interaction. The projector, the camera, the illuminator, and the computer system are located on the same side of the window.

Abstract: A method and system for processing captured image information in an interactive video display system. In one embodiment, a special learning condition of a captured camera image is detected. The captured camera image is compared to a normal background model image and to a second background model image, wherein the second background model is learned at a faster rate than the normal background model. A vision image is generated based on the comparisons. In another embodiment, an object in the captured image information that does not move for a predetermined time period is detected. A burn-in image comprising the object is generated, wherein the burn-in image is operable to allow a vision system of the interactive video display system to classify the object as background.

Abstract: A method for managing an interactive video display system. A plurality of video spots are displayed on the interactive video display system. Data based on interaction with the interactive video display system corresponding to video spots of the plurality of video spots is gathered. The data is stored, wherein the data is for use in managing presentation of the video spots. By analyzing data relating to different video spots, popularity and other metrics may be determined for the video spots, providing useful information for managing the presentation of the video spots.

Abstract: An ignition coil, spark plug, and pressure sensor for an internal combustion engine are, in a preferred embodiment, integrated into a single assembly and mounted directly on a plug hole of an internal combustion engine. A hard spark plug shell serves as a pressure member and on which a strain gage is affixed. Changes in the pressure in the combustion chamber deform the shell, causing a corresponding change in the resistance of the strain gage. A bridge circuit or the like is used to measure the resistance change thereby providing a direct indication of cylinder pressure.

Abstract: A method for changing visual attributes presented by a graphical user interface of a device such as a mobile electronic device by loading onto the device a file containing information for changing selected visual attributes of the interface. A method or compiler for generating or compiling a file that contains information used by a device to change the user interface presented by the device.

Abstract: A system and method are provided for localizing applications that are used with hand-held electronic devices.

Abstract: An interactive directed beam system is provided. In one implementation, the system includes a projector, a computer and a camera. The camera is configured to view and capture information in an interactive area. The captured information may take various forms, such as, an image and/or audio data. The captured information is based on actions taken by an object, such as, a person within the interactive area. Such actions include, for example, natural movements of the person and interactions between the person and an image projected by the projector. The captured information from the camera is then sent to the computer for processing. The computer performs one or more processes to extract certain information, such as, the relative location of the person within the interactive area for use in controlling the projector. Based on the results generated by the processes, the computer directs the projector to adjust the projected image accordingly.

Abstract: A system and method of instant messaging is provided. A plurality of messaging clients capable of transmitting instant messages to one another are each configured to share presence information with one another via a network. A determination is made, with respect to each of the messaging clients, as to whether the messaging client is in a state in which it is receptive to receiving presence information from the other messaging clients, and if so, then the presence information is provided to the messaging client. The presence information may be provided directly between the messaging clients, or it may be provided through one or more centralized proxy servers that store and propagate the presence information. A special state is provided, referred to herein as the unknown state, which when entered by a particular messaging client will cause the system to cease further transmissions of presence information to that client and/or transmissions about that client.

Abstract: A system and method are provided for drawing graphics, such as to display a user interface on a display of a mobile device. A graphics stack is used to store pre-computed coordinate values to improve performance for drawing graphics, such as to display a user interface on a display of a mobile device.

Abstract: A device allows easy and unencumbered interaction between a person and a computer display system using the person's (or another object's) movement and position as input to the computer. In some configurations, the display can be projected around the user so that that the person's actions are displayed around them. The video camera and projector operate on different wavelengths so that they do not interfere with each other. Uses for such a device include, but are not limited to, interactive lighting effects for people at clubs or events, interactive advertising displays, etc. Computer-generated characters and virtual objects can be made to react to the movements of passers-by, generate interactive ambient lighting for social spaces such as restaurants, lobbies and parks, video game systems and create interactive information spaces and art installations. Patterned illumination and brightness and gradient processing can be used to improve the ability to detect an object against a background of video images.

Abstract: A wall paneling system is provided in which panels of various widths are pre-fabricated with raised moldings. The panels are thin enough to be easily cut, if necessary, and applied to a wall by an inexperienced installer with adhesive. Various chair rails and baseboards are provided. By providing the panels in different standard widths, they can be easily pieced together to cover walls of any length, thereby enabling an inexperienced installer to easily complete the lower wall paneling of an entire room. Corner moldings are provided to cover any gaps where the panels meet in corners of a room.
