Abstract: This invention relates to an apparatus for the projection of a remote conferee's presence into a group meeting environment by usin a combination of videoconferencing/teleconferencing and robotics technology. The remote conferee's face is shown substantially life-size on a video monitor. The remote conferee's eyes appear to be looking directly at the viewer. The video monitor can turn left or right to point at the person speaking, automatically or by manual control, to give the impression that the remote conferee is turning his head to look at the person speaking. The video screen can be raised and lowered to give the impression that the remote conferee is standing up and sitting down. An attention-getting mechanism prompts the attention of the other conferees when the remote conferee wants to interrupt or enter a conversation.

Abstract: Optical transmissivity-dependent parameters (90) including yarn denier (20) are monitored on-line in real-time with a preferably microprocessor-controlled high frequency modulated-demodulated optically-bas ed system. A periodically driven LED (100) outputs preferably collimated light signal (120) and is spaced-apart from an array o f preferably identical photodetector ("PD") diodes (110A-C) that will track one another. The yarn (20) is spaced between one of the PDs and yarn characteristics can affect PD-received light. A first PD (110A) output feedback to the LED driver to compensate the system against factors affecting LED driver to compensate the system against factors affecting LED transmission and PD light reception. A second PD (110B) output is coupled to a fraction of the drive signal to enhance dynamic range. This signal is amplified, AC-coupled, sample-and- held during a stable active portion of the LED drive signal to demodulate the relevant signal. The digitized sampled held magnitude enables a CPU to provide denier and other yarn characteristics measurement data. A third PD (110C) helps self-calibrate the system.

Abstract: The invention relates to a method for the production of polyurethane-based technical formed parts, commodity goods and objects, preferably consisting of (meth)acrylate containing isocyanate and hydroxy groups and at least 0.5 mMol/g reactive double bonds that can be determined using a DSC method. In a first step, a mixture of all starting constituents is produced and given a desired form using methods such as casting, pressing, rolling or extruding that are known per se in plastic engineering technology, whereby said mixture simultaneously or subsequently undergoes a non-radically triggered polyaddition reaction (urethane reaction) and a polyurethane substance is created in the form of a flexible, optionally elastic pre-form that can be deformed without any removal of said material. In a second step, the pre-form undergoes preferably mechanical shaping in addition to substantially emissio n- free hardening by means of radical polymerization of the free double bonds. The invention also relates to products that are manufactured using this method in addition to multiple applications thereof, such as directly in the place where they are used, in order to produce highly resistant shaped bodies and composite elements that can be used more particularly in fields such as medicine (e.g. surgery, orthopaedics, dental medicine), technology (e.g. civil engineering, the construction industry, motor vehicle production, insulation technology, measuring and lighting technology), the home, cosmetics and fine art.

The tension force adjustable prestressed girder for adjusting a load-resisting force which consists of an upper flange (28) supporting an upper deck of a bridge installed thereon, a body portion (22), and a lower flange (24) which includes tension steel wires (27) provided in a lengthwise direction of the girder (40) and tensioned to compensate for the load-resisting force, and at least one or more non-tension steel wires (27a) provided in the lengthwise direction of the girder, so that the load-resisting force of the bridge or building can be increased by tensioning the non-tension steel wires. Thus, cracks and sagging of a girder generated due to long-term deterioration, creep or overload can be corrected by additionally tensioning steel wires installed internally or externally at a girder of the bridge or building.      Thus, repair and reinforcement of the bridge or building is easy so that the load-resisting force of the bridge or building can be easily increased. Also, by adjusting the tension force step by step, the girder can be economically manufactured or the height of the girder can be decreased.

Title: Lateral mode stabilizer for coriolis flowmeter
Inventor: OLLILA CURTIS JOHN
IPC: G01F1/84
Filed: 2000-01-20
Granted: 2004-05-25
Abstract: Signal processing of Coriolis flowmeter output signals is improved by increasing the frequency separation between the flow tube drive frequency and unwanted lateral mode vibration frequencies. A cylindrical lateral mode stabilizer surrounds the flow tube near each flow tube end and is positioned between the flow tube and a surrounding balance bar. Axially lateral extensions on opposing circumferential sides of each lateral mode stabilizer element stiffen the flow tube ends for only lateral vibrations. This raises the lateral mode vibration frequency of the flow tube while leaving the drive mode frequency relatively unaffected.
