Shielded safety syringes.
To the Editor: The results of the study, “Impact of a Shielded Safety Syringe on Needlestick Injuries Among Healthcare Workers,” in the June 1992 issue (1992;13:349353) are encouraging. Technology that keeps the worker’s hands behind the needle at all times and covers the needle after use should significantly lower the rate of needlestick injuries. However, we noted the following inconsistencie...
متن کاملShielded Wires and Wiring
Shielded conductors permit the transmission of low level signals, at high impedance levels, through areas where excessive interference voltages would be induced into low impedance conductors by low frequency magnetic fields, or in areas where sensitive information must be sent. Shields on wires act the same as shields on rooms, the continuous enclosure acting as a Faraday cage barrier to radiat...
متن کاملShielded biplanar gradient coil design.
An application of the target field method to the design of shielded biplanar gradient coils for magnetic resonance imaging electromagnets is presented. Some specific cases are studied, and optimized geometries are proposed for the axial and transverse gradient coils that eliminate the third- and minimize the fifth-order terms in the magnetic field expansion.
متن کاملDouble shielded Public Key Cryptosystems
By introducing extra shields on Shpilrain and Ushakov’s Ko-Lee-like protocol based on the decomposition problem of group elements we propose two new key exchange schemes and then a number of public key cryptographic protocols. We show that these protocols are free of known attacks. Particularly, if the entities taking part in our protocols create their private keys composed by the generators of...
متن کاملRobotic Shielded Metal Arc Welding
In this work, the development and validation of a methodology for robotic welding with covered electrodes (SMAW) using a variation of the tool center point (TCP) model is shown. The covered electrode becomes part of the kinematic model of the robot as an additional prismatic joint, whose movement is determined by the electrode consumption or melting rate. This allows programming the trajectory ...
