    • An interactive computer program for seaming a number of images into a panorama. Various parameters which affect how the images are seamed can be changed interactively. Parameters such as position, orientation, focal length, which image will be visible where images overlap, and the opacity curve can be changed. The result of any change is immediately visible. A user can move the control points, thereby “morphing” or distorting the contribution to the panorama of an image. Each pixel is assigned an “alpha” value which indicates the opacity value of that pixel in an area where images overlap. Alpha values can be changed according to a pre-established curve. The original images are not changed. Instead, only the transform between the original images and the final panorama is changed.
    • 用于将多个图像接合到全景中的交互式计算机程序。 可以交互地改变影响图像被缝合的各种参数。 诸如位置,方向,焦距,图像在图像重叠时可见的参数和不透明度曲线等参数都可以改变。 任何更改的结果立即可见。 用户可以移动控制点,从而“变形”或扭曲对图像全景的贡献。 每个像素被分配一个“alpha”值,它表示图像重叠的区域中该像素的不透明度值。 Alpha值可以根据预先建立的曲线进行更改。 原始图像未更改。 相反,只有原始图像和最终全景图之间的变换才会改变。

    • Movement through multi-dimensional space is simulated using a series of panoramic images which are projected or displayed in sequence. The user's direction of view, that is the selected view window, is maintained as the series of images is projected or displayed. Motion in directions other than forward or reverse is simulated by utilizing “branch” points in the sequence. Each path from a branch point simulates motion in a different direction. Branch points are generally indicated to a viewer by visual indicators called “hot spots”; however, branch points may also be hidden and activated in response to the viewer's selected direction of view. If a branch point is indicated by a visual indicator, a user can select motion in a desired direction by clicking on a “hot spot”. In order to conserve storage space, the image representing each panorama can be stored in a compressed format. Only the portion of the panorama necessary to create a “view window” that is, the portion of the image displayed in response to the user's direction of view, is decompressed at view time. An index methodology is used to store the panoramic images. Use of the indexing methodology allows the images to be retrieved in both the forward and backward direction to simulate movement in either direction. Sound is provided in a special format, so that special effects can be provided based on the user's point of view and dependent upon the direction of motion selected by the user.

    • The present invention provides a very flexible, digital system for capturing and storing panoramic images using progressive scan (that is, non interlaced) technology. The system includes a digital image input device and an associated control computer. Since the image capture device is digital it can be easily and flexibly controlled by software in the control computer. The image input device has six lenses positioned on the six faces of a cube. While the image input system can have other lens configurations, the use of six lenses in a cubic configuration is optimal for a system that is used to capture a spherical panorama. The six lenses simultaneously focuses different images on six CCDs (Charge Coupled Devices). The image input device also includes an embedded controller, and data compression circuitry. The embedded controller controls the exposure time of the CCDs (i.e. the effective aperture and effective shutter speed) and reads image data from the CCDs. The image data read from the CCDs is compressed, multiplexed, and sent to the control computer. The control computer stores the images in frames, each of which have one image from each of the six lenses. Each frame includes six images that were simultaneously recorded and any associated information, such as audio tracks, textual information, or environmental information such as GPS (Global Position System) data or artificial horizon data. The control computer includes a user interface which allows a user to specify control information such as frame rate, compression ratio, gain, etc. The control computer sends control information to the embedded controller which in turn controls the CCDs and the compression circuitry. The images can be sent from the control computer to a real time viewer so that a user can determine if the correct images are being captured. The images stored at the control computer are later seamed into panoramas and made into panoramic movies.

    • Backlash in a fishing reel is eliminated by automatically matching the reel discharge speed to the line speed. The drag on the reel is automatically adjusted so that the reel discharge speed does not exceed the line speed. The invention includes a reel, a mechanism for measuring the relationship between the line speed and the reel discharge speed, an electronically controlled braking device and a microprocessor for controlling the braking device in response to the relationship between the line speed and the reel discharge speed. When the reel discharge speed exceeds the line speed additional braking is applied. One alternative embodiment of the invention intermittently applies a very short pulse of braking action to the reel. The response to this pulse of braking action is detected and used to determine if the reel discharge speed exceeds the line speed.

    • Group message delivery in a time multiplexed paging system is accomplished by providing in normal message packets a group ring indicator. A paging device collecting a message interrogates the group ring indicator to determine availability of a pending group message. If a group message is available, the paging device can target a dedicated time slot associated with group message transmission. In this manner, a single transmission of a group message is made available to all paging devices of the paging system. In one embodiment, the group ring indicator is a single bit indicating merely availability of a pending group message, the paging device then targeting and collecting the available group message to determine whether the paging device subscribes to that particular group message service. In a second embodiment, the group ring indicator indicates not only availability of a group message, but also the type of group message available. The paging device thereby determines based on the value of the group indicator whether the indicated available group message need be pursued.
    • 在时间复用寻呼系统中的组消息传送通过在正常消息分组中提供组环指示来实现。 收集消息的寻呼设备询问组响铃指示符以确定待决组消息的可用性。 如果组消息可用,则寻呼设备可以针对与组消息传输相关联的专用时隙。 以这种方式,组消息的单个传输对寻呼系统的所有寻呼设备是可用的。 在一个实施例中,组响铃指示符是仅指示待决组消息的可用性的单个位,然后寻呼装置定向并收集可用组消息以确定寻呼装置是否订阅该特定组消息服务。 在第二实施例中,组响铃指示器不仅指示组消息的可用性,还指示可用组消息的类型。 因此,寻呼装置基于组指示符来确定是否需要追踪所指示的可用组消息。
