摘要： The present invention relates to a method for transmitting image data for superimposed images via wireless devices in a radio frequency communication system. The original image is transmitted via a communication channel to a receiving unit. The original image is then revised to form a revised image. The revised image is compared to the original image to determine the differences between the revised image and the original image. These differences comprise a difference image which is then transmitted to the receiving party. At the receiving end, the difference image is recombined with the previously-transmitted original image to reform the revised image. In a preferred embodiment, the original images and difference images are preferably decomposed and progressively transmitted to the receiving unit in response to image data requests from the receiving unit.

摘要： The present invention relates to a method for transmitting multiresolution audio signals via wireless devices in a radio frequency communication system wherein audio signals are decomposed into levels of resolution. The audio signal is decomposed into levels including a base signal at a base transmission rate and one or more signal details and input into a code rate selector, controlled by either party to the communication. The base signal represents the coarsest resolution or quality of the signal. Each signal detail, when added to the base signal, improves the resolution of the signal by increasing the detail and the transmission rate. An audio receiving unit transmits a request for audio transmission to the audio transmitting unit. In response to the initial request, the base signal is transmitted to the audio receiving unit. If the base signal is insufficient, the sound quality can be increased incrementally by sending further requests to transmit additional signal detail from the code rate selector. The additional signal detail is then recombined with the base signal at the audio transmitting unit to provide a higher level of sound quality to the signal. The higher quality audio signal is then transmitted to the audio receiving unit.
摘要翻译：本发明涉及一种在射频通信系统中通过无线设备发送多分辨率音频信号的方法，其中音频信号被分解成分辨率水平。音频信号被分解为包括基本传输速率的基本信号和一个或多个信号细节的等级，并输入到由通信的任一方控制的码率选择器中。基本信号表示信号的最粗分辨率或质量。每个信号细节，当添加到基本信号时，通过增加细节和传输速率来提高信号的分辨率。音频接收单元向音频发送单元发送音频传输请求。响应于初始请求，基本信号被发送到音频接收单元。如果基本信号不足，则可以通过发送进一步的请求从码率选择器发送附加信号细节来增加声音质量。然后，附加信号细节与音频发送单元处的基本信号重组，以向信号提供更高水平的声音质量。然后，较高质量的音频信号被发送到音频接收单元。

摘要： The present invention relates to a method for transmitting multiresolution image data via wireless devices in a radio frequency communication system wherein images are decomposed into levels of resolution. The image data is stored in discrete information blocks in an image storage unit including a base image and one or more image details. The base image represents the coarsest resolution of the image. Each image detail, when added to the base image, improves the resolution of the image. An image display unit transmits a request for image data to the image storage unit. In response to the initial request, the base image is transmitted to the image display unit. If the base image is insufficient, the resolution can be increased incrementally by sending additional image data requests to transmit additional image detail. The additional image detail is then transmitted to the image display unit and recombined with the base image to provide a higher level of resolution to the image.

摘要： A watercraft has a laterally extendable deck or room extension that is extended by sliding along guides or bearings. The deck or room extension can be extended using a motor, gear pinion and rack arrangement, a hand crank arrangement, a hydraulic cylinder arrangement, or a linear motor arrangement. A keel ballast can be utilized to counterbalance the eccentric load caused by the overhanging deck or room extension.

摘要： A structure, which interlocks a relatively thin sheet of material with a relatively heavy member, for example, a hub member with a sheet metal fan structure, comprises the hub on one end having a groove dividing the hub into an inner sleeve-like shoulder having a length substantially greater than the thickness of the sheet-like member, the groove has a wider base than the throat adjacent a second outwardly extending shoulder on which the member rests. The sleeve is cut into a plurality of segments with alternate segments being deformed to force a portion of the edge of the sheet-like member into the groove to form a spline connection with the hub.

摘要： A structure for interlocking relatively thin sheet material with a relatively heavy member, such as, for example a hub member with a sheet metal fan blade structure and the like to provide a rigid durable interlocking connection therebetween, in which, in the example given, the hub member is provided with an annular sleeve which extends through a bore in the central portion of the fan blade or other member, the hub member having an upstanding flange in the form of an annular shoulder spaced rearwardly from the free end of the sleeve and of greater diameter than the latter, with the shoulder being radially spaced from the sleeve by a groove having a radial width approximately equal to the thickness of the sheet member. The sleeve is divided into a plurality of segments, alternate segments flaring outwardly into engagement with the material of the blade member forming the periphery of the bore therein, and the free ends of the intermediate segments being bent over and forced into the material of the sheet member, moving the adjacent material thereof into the groove and forming, in effect, a spline-like connection between the two members.
