[en] Emerging technologies in the field of ''Test ampersand Measurement'' have recently enabled the development of the Rapidly Adaptable Instrumentation Tester (RAIT). Based on software developed with LabVIEW, the RAIT design enables quick reconfiguration to test and calibrate a wide variety of telemetry systems. The consequences of inadequate testing could be devastating if a telemetry system were to fail during an expensive flight mission. Supporting both open-bench testing as well as automated test sequences, the RAIT has significantly lowered total time required to test and calibrate a system. This has resulted in an overall lower per unit testing cost than has been achievable in the past

[en] This paper identifies the requirements for the International Thermonuclear Experimental Reactor metrology and viewing system, and describes a remotely operated precision surface mapping system. A metrology system capable of achieving sub-millimeter accuracy must operate in a reactor vessel that has high gamma radiation, high vacuum, elevated temperature, and magnetic field. A coherent, frequency modulated laser radar system is under development to meet these requirements. The metrology/viewing sensor consists of a compact laser optics module linked through fiber optics to the laser source and imaging units, located outside the harsh environment. The deployment mechanism is a remotely operated telescopic-mast. Gamma irradiation to 10⁷ Gy was conducted on critical sensor components at Oak Ridge National Laboratory, with no significant impact to data transmission, and analysis indicates that critical sensor components can operate in a magnetic field with certain design modifications. Plans for testing key components in a magnetic field are underway. (orig.)

[en] The corrosion behaviour of three aluminium based alloys (AlSi 12, AlMg5 and AlSi 5Mg) when exposed to aqueous media containing chloride is investigated; these alloys are used in the manufacturing of telecomunication equipment. Accelerated corrosion testing and salt spray tests were carried out. The results include polarization curves obtained with three kinds of aqueous solutions (the first containing only 3% NaCl and the others, 3% NaCl and small amounts of Fe ³⁺ and Cu²⁺ ions). (C.L.B.)

[en] LOFT, the Large Observatory For X-ray Timing, was one of the ESA M3 mission candidates that completed their assessment phase at the end of 2013. LOFT is equipped with two instruments, the Large Area Detector (LAD) and the Wide Field Monitor (WFM). The LAD performs pointed observations of several targets per orbit (90 minutes), providing roughly 80 GB of proprietary data per day (the proprietary period will be 12 months). The WFM continuously monitors about 1/3 of the sky at a time and provides data for about 100 sources a day, resulting in a total of 20 GB of additional telemetry. The LOFT Burst alert System additionally identifies on-board bright impulsive events (e.g., Gamma-ray Bursts, GRBs) and broadcasts the corresponding position and trigger time to the ground using a dedicated system of 15 VHF receivers. All WFM data are planned to be made public immediately. In this contribution we summarize the planned organization of the LOFT ground segment (GS), as established in the mission Yellow Book. We describe the expected GS contributions from ESA and the LOFT consortium. A review is provided of the planned LOFT data products and the details of the data flow, archiving and distribution. Despite LOFT was not selected for launch within the M3 call, its long assessment phase ( ≥2 years) led to a very solid mission design and an efficient planning of its ground operations. (authors)

[en] With the growth of computing power and the development of information technology in the last few years, the tendency for the development of unmanned vehicles has increased. Many leading corporations sponsor this industry. Since the creation of the concept of an unmanned vehicle implies that the computing systems in its composition must make decisions about the method and direction of its further movement, predict the further actions of the traffic participants and move in accordance with the rules of the road, these vehicles are equipped with powerful telemetry systems that allow to accurately evaluate surroundings. But, since there is a problem in incomplete data from one device (sensor), in this article, using a specific example, sensor fusion technology is considered that allows combining data from several sensors to achieve maximum results in solving problems of developing an unmanned vehicle.

[en] Positional information about movable components in a machine system relative to the workpiece is wirelessly transmitted by infrared radiation to a remote receiver. The receiver is operative to convert the infrared signals into electrical signals for controlling operational cycles of the machine system

[en] Maturing female anadromous salmonids receiving surgical intraperitoneally-implanted telemetry transmitters may experience difficulty depositing eggs during natural spawning. We allocated maturing adult steelhead females to three treatments: tags surgically implanted in the body cavity (internal), tags implanted between the skin and muscle tissue (subdermal), and non-tagged, and allowed them to spawn naturally in an experimental channel. Internally tagged females retained significantly more eggs than both the subdermally tagged treatment (P = 0.005) and non-tagged controls (P = 0.001); the subdermal and non-tag controls did not differ significantly (P = 0.934). The internal, subdermal and non-tag treatments retained an average of 49%, 11% and 2% of their eggs, respectively. The onset of sexual activity did not differ significantly among treatments (P = 0.413). Post-spawning mortality was 70% for both internally and subdermally tagged females and 0% for non-tagged females (P <0.01). We suggest that subdermal implantation techniques be considered in future studies during the reproductive period to reduce egg retention caused by internal implantation of transmitters

[en] Teleradiology is a means of electronically transmitting radiographic patient images and consultative text. This offers a new way to communicate with other radiologists and transferring clinicans. Different applications of teleradiology, such as on-call services for emergency departments or rural regions, as well as expert consultation (second opinion) already have been realised. Especially in concern of dental radiography, analog (film-based) imaging gets progressively replaced by digital imaging. The combination with ultrafast data transfer offers an increasing efficacy in diagnosis and therapy, accelleration of communication and new means of quality assement in patient care. Various applications of teleradiology concerning dental medicine are discussed. (orig.)
