A video signal generating apparatus comprises a first microprocessor (10) including a memory (16) for receiving and storing in non-real time instructions for the generation of a range of video signals, such as test patterns, digital multi-effect keys or wipe patterns for a digital switcher, and a second microprocessor (14) for reading the instructions and generating a selected required video signal in real time.
摘要:
A castable, energetic, plastic-bonded explosive containing glycidyl azide lymer (GAP) an energetic polymer binder combined with the energetic plasticizers trimethyloethane trinitrate (TMETN) and trimethylene glycol dinitrate (TEGDN) or bisdinitropropyl formal and acetal mixture (BDNPF/A), and the explosive solid cyclotetramethylene tetranitramine (HMX) or cyclotrimethylene trinitramine (RDX) having the desirable mechanical properties, insensitivity, and excellent aging properties at much higher solids loading and thus explosive performance than previous compositions. The invention uniquely combines the high energy of high solids loading combined with energetic polymers and plasticizers to provide the insensitivity of rubbery explosive compositions.
摘要:
A porous carbon is prepared by first carbonizing a solid fraction (obtained from pitch and/or coal by solvent extraction and preferably being one soluble in quinoline and insoluble in methanol, n-heptane and toluene) to produce a first porous carbon, absorbing into the first porous carbon liquid fraction (obtained from pitch and/or coal by solvent extraction and preferably being one insoluble in methanol and soluble in n-heptane, toluene and quinoline and/or one insoluble in methanol and n-heptane and soluble in toluene and quinoline), and carbonizing the first porous carbon containing adsorbed liquid fraction to give a second porous carbon having a specific surface area greater than that of the first porous carbon. The first porous carbon may, prior to absorption therein of the liquid fraction, be `activated` e.g. by heating in air, to increase its pore size as may the second porous carbon. The porous carbon obtained may be used as a catalyst support.
摘要:
Apparatus uniquely identifies material recorded on an example of a recording medium. The medium has distinguishing data, a tape ID, distinguishing that example from other examples thereof recorded thereon. A generator generates data, e.g. IN and OUT time codes, identifying the or each piece of material recorded on the medium. A recorder (460) records the said distinguishing data on the medium. A reproducer (460) reproduces, from the recording medium, the distinguishing data. A processor, a PDA (469) associates the reproduced distinguishing data and the said identifying data with a unique identifier, a UMID, for the or each piece of material. A database (464) associates the unique identifier with metadata relating to the material.
摘要:
An audio and/or video generation apparatus comprises a recording processor which is operable to record audio and/or video signals on a recording medium, a meta data generation processor which is operable to generate meta data identifying the content of the audio/video signals, and a communications processor which arranged to communicate the meta data separately from the recording medium.Furthermore, the meta data generation processor may be operable to generate at least one sample image which is representative of a video image from the recorded video signals, and to associate the sample image with an address on the recording medium at which the video image is recorded. The video and/or audio generation apparatus provides an advantage in generating and utilising meta data to facilitate the generation of audio/video productions. Accordingly, a system for generating an audio and/or video production comprises an acquisition processor operable in use to receive instructions from a user which instructions are representative of a list of content items for the audio and/or video production. The audio and/or video generation apparatus is arranged in use to receive information representative of the list of content items, and to generate audio and/or video signals in accordance with the content items on the list. An ingestion processor may be provided to receive the list of content items, and the audio and/or video signals and to form the audio and/or video production by associating the audio and/or video signals with the list of content items.
摘要:
A system and methods with which changes in microstructure properties such as grain size, grain elongation, texture, and porosity of materials can be determined and monitored over time to assess conditions such as stress and defects. An example system includes a number of ultrasonic transducers configured to transmit ultrasonic waves towards a target region on a specimen, a voltage source configured to excite the first and second ultrasonic transducers, and a processor configured to determine one or more properties of the specimen.
