A robot-guided system to assist orthopaedic surgeons in performing orthopaedic surgical procedures on pre-positioned inserts, including for the fixation of bone fractures, and especially for use in long bone distal intramedullary locking procedures. The system provides a mechanical guide for drilling the holes for distal screws in intramedullary nailing surgery. The drill guide is automatically positioned by the robot relative to the distal locking nail holes, using data derived from only a small number of X-ray fluoroscopic images. The system allows the performance of the locking procedure without trial and error, thus enabling the procedure to be successfully performed by less experienced surgeons, reduces exposure of patient and operating room personnel to radiation, shortens the intra-operative time, and thus reduces post-operative complications.

A camera portion of a portable consumer device obtains data from a field of view, and at least a portion of the data is used to determine existence of an object in the field of view for which the information is available from a reference source. An indication is then provided to the user that the object is in the field of view. This can all be accomplished by a functionality, such as computer software, that executes on one or both of the device and a distal server. Objects within the field that the system can identify and provide information are deemed “linkable.” Once a user is presented with an indication of which objects around him are linkable, he can then directly point and click on the linkable objects without the “trial-and-error” process of pointing and clicking on non-linkable objects.

The most significant features in visual scenes, is identified without prior training, by measuring the difficulty in finding similarities between neighbourhoods in the scene. Pixels in an area that is similar to much of the rest of the scene score low measures of visual attention. On the other hand a region that possesses many dissimilarities with other parts of the image will attract a high measure of visual attention. A trial and error process is used to find dissimilarities between parts of the image and does not require prior knowledge of the nature of the anomalies that may be present. The use of processing dependencies between pixels avoided while yet providing a straightforward parallel implementation for each pixel. Such techniques are of wide application in searching for anomalous patterns in health screening, quality control processes and in analysis of visual ergonomics for assessing the visibility of signs and advertisements. A measure of significant features can be provided to an image processor in order to provide variable rate image compression.

A representation of a codeword is decoded by applying a first decoder of the codeword to the representation of the codeword. If applying the first decoder fails to decode the representation of the codeword then a second decoder of the codeword is applied to the representation of the codeword. Preferably, applying the first decoder consumes less power and is faster than applying the second decoder. Data are ported by encoding the data as a codeword, exporting the codeword to a corrupting medium, importing a representation of the codeword, and applying a first decoder to the representation of the codeword. If applying the first decoder fails to decode the representation of the codeword then a second decoder of the codeword is applied to the representation of the codeword.

The invention discloses a device for eliminating local oscillation leakage. During operation, the device comprises: generating an intermediate frequency auxiliary signal with adjustable amplitude and phase in a baseband digital domain and converting the intermediate frequency auxiliary signal into an analog radio-frequency modulation signal; converting the intermediate frequency auxiliary signal into a negative local oscillation signal with the frequency and amplitude identical to those of a local oscillation leakage signal and the phase opposite to that of the local oscillation leakage signal; and offsetting the negative local oscillation signal and the local oscillation leakage signal to realize the function of eliminating local oscillation leakage. The device can carry out dynamic adjustment of signal amplitude and phase in a digital domain through the adoption of a trial-and-error method according to the offset local oscillation leakage state till the local oscillation leakage signal meets requirements. Because the signal offsetting the local oscillation leakage signal is generated in the digital domain, the amplitude and phase of the signal can be adjusted accurately. The device has a simple method and can quickly realize accurate control of local oscillation leakage elimination. In addition, the device does not influence the normal operation of a transmitter during adjustment.

Systems and methods for providing access to an information stream in a format customized for a receiving device involve a network-based information storage and distribution system for receiving, storing, and distributing an information stream to a user of the information stream over a network. When a user attempts to access the media files, such as by browsing a site containing the media files or clicking on a link to the media files, a determination is made as to the type of device attempting to access the files. If the device is unknown to the system, a trial-and-error method is used to update a database of devices and what file formats, resolutions, codecs, etc., they support. Then, the selected media files are displayed or made available for download or transmission to the user's device in a format compatible with the particular device, and future access attempts by that type of device are facilitated.

The invention relates to generation and update based on event playback experience. An exemplar method, a device, and a system used to capture, organize, share and/or display media can be disclosed. By using all the disclosed embodiments, the uniform playback and the browse experience can be automatically created correspondingly to the media integration. For example, the trial-and-error method and the metadata can be used to combine the commentary, and add the same to the media data. In addition, when more media are added to the integration, the expression of the media can be dynamically restructured by itself. Although the integration can use the content of the single user, but sometimes, the expectation includes that the media of the integration is captured by a friend and or other people in the same event. In some embodiments, the media content related to the event can be automatically collected and shared in the selected group. Besides, in some other embodiments, new media can be automatically included in the media integration related to the event, and the playback experience can be dynamically updated.

A noninvasive method of slimming a patient's body by concurrently applying laser energy of two different wavelengths to the patient. In the preferred embodiment, the laser treatment uses one wavelength of about 635 nm and another wavelength of about 532 nm. Preferably the laser energy is applied using a circular beam spot created by a line swept through a 360° circle. By using two wavelengths concurrently in the treatment regimen, the patient avoids the inconvenience and expense of the trial-and-error approach of undergoing a complete treatment regimen unsuccessfully with a first wavelength, and then subsequently undergoing a second complete treatment regimen using a second wavelength.

A system for tagging articles. A glass is fabricated from (1) a combination of oxides and (2) one or more rare earth elements. The glass is divided into particles or fragments, which are attached to the article. When the particles are excited by specific radiation, they emit a characteristic signature, in terms of a collection of frequencies, each frequency having a characteristic amplitude and decay time. However, the particles cannot be counterfeited, or reverse-engineered, because, at present, no systematic data is available which correlates a particle's characteristic signature with the composition and processing of the particle itself. Thus, at best, a trial-and-error approach must be taken in attempts at counterfeiting, which is considered impossible.
