摘要:
An airfoil for a gas turbine engine blade includes a plurality of film cooling holes extending through its outer surface. The film cooling holes are formed by defining at least a first datum structure and a second datum structure, and then forming each film cooling hole at a location on the airfoil outer surface relative to the first and second datum structures. As a result, each film cooling hole has a centerline extending therethrough that forms a compound angle with respect to a tangent to the outer surface, and the distance between the centerlines of each film cooling hole is at least a predetermined minimum distance.

摘要:
A surveillance video system may include a first device configured to process successive surveillance image files of a common area into an image transport stream for a selectable region of interest within the common area. The surveillance video system also may include a second device remote from the first device and in communication with the first device. The second device may include a display and a processor cooperating therewith. The processor may be configured to scroll the selectable region of interest to maintain a selected moving target visible on the display.

A video processing system may include a display and a video processor coupled to the display. The video processor may be configured to display a georeferenced video feed on the display defining a viewable area, determine actual geospatial location data for a selected moving object within the viewable area, and generate estimated geospatial location data along a predicted path for the moving object when the moving object is no longer within the viewable area and based upon the actual geospatial location data. The video processor may be further configured to define a successively expanding search area for the moving object when the moving object is no longer within the viewable window and based upon the estimated geospatial location data, and search within the successively expanding search area for the moving object when the successively expanding search area is within the viewable area.
摘要:
A surveillance video system may include a surveillance image database storing a sequence of surveillance image files for a common area having geospatial metadata associated therewith. A processor may cooperate with the surveillance image database and configured to transcode the surveillance image files into a sequence of surveillance video frames retaining the geospatial metadata. The processor may also be configured to assemble a surveillance video transport stream from the sequence of surveillance video frames retaining the geospatial metadata, and to selectively deliver the surveillance video transport stream retaining the geospatial metadata to at least one surveillance video user.

A multimedia system may include at least one audio comment input device configured to permit at least one commentator to generate audio comment data based upon viewing video data from a video source. Furthermore, a media processor may cooperate with the at least one audio comment input device and be configured to process video source data and audio comment data and generate therefrom audio trigger markers synchronized with the video source data for predetermined audio triggers in the audio comment data, and combine the video source data, the audio comment data, and the audio trigger markers into a media data stream.
摘要:
A gas diffusion electrode and method of making the same. According to one embodiment, the electrode comprises a support layer, a first cushioning layer positioned on top of the support layer, a second cushioning layer positioned on top of the first cushioning layer, and a catalyst layer positioned on top of the second cushioning layer. The support layer is a mechanically stable, electrically-conductive, gas porous substrate, such as carbon fiber paper. The first cushioning layer, which is also gas porous, comprises a non-woven mat of electrically-conductive, chemically-inert fibers, preferably carbon nanofibers, bound together with a polymeric binder, such as polytetrafluoroethylene. The second cushioning layer is similar to the first cushioning layer, except that carbon black or a similar electrically-conductive, chemically-inert particulate material is included in addition to or instead of the fibrous material for the purpose of fine-tuning pore size.

A method of electrical isolation for printed circuit board gasketing is disclosed for enabling gasketing to overlay plated through holes without shorting out thereto. The method of electrical isolation for printed circuit board gasketing includes counterboring at a controlled width to a controlled depth those plated through holes underlying the gasketing. The method provides the advantage of being able to overlay gasketing on both surfaces of a printed circuit board mid-plane. The method of electrical isolation for printed circuit board gasketing is particularly useful for overcoming the additional material requirements and processing steps of electrical isolation known in the art.
摘要:
A method of inducing hyperthermia in at least a portion of a target area—e.g., a tumor or a portion of a tumor or targeted cancerous cells—is provided. Targeted RF absorption enhancers, e.g., tumor infiltrating lymphocytes (TILs) containing RF absorbing particles, are introduced into a patient. These targeted RF absorption enhancers will target certain cells in the target areas and enhance the effect of a hyperthermia generating RF signal directed toward the target area. The targeted RF absorption enhancers may, in a manner of speaking, add one or more RF absorption frequencies to cells in the target area, which will permit a hyperthermia generating RF signal at that frequency or frequencies to heat the targeted cells.
摘要:
A method and system for speculatively issuing instructions which are dependent upon results from execution of other instructions. Instructions are speculatively issued, dependent upon a result from execution of a primary instruction, wherein the speculatively issued instructions are issued after execution of the primary instruction. N clock cycles are tracked after execution of the primary instruction, wherein the result from execution of said primary instruction is expected within n clock cycles. Execution of any speculatively issued instructions which are dependent upon the primary instruction is cancelled if the result is not returned from execution of the primary instruction within n clock cycles, such that for primary instructions for which the result is returned within the expected n clock cycles any speculatively issued instructions dependent upon said result are executed with increased efficiency.
