Publication number: 20140230514Abstract: A pneumatic press with high slide acceleration and velocity is equipped with an arrangement trigger mechanism for holding the slide, upper die, and punch in place until air pressure force in tons is exerted against slide opposite the upper die and punch. When the trigger mechanism releases the slide, upper die, and punch in a short travel the velocity is very high. This will permit the punch to enter the part material at the strain rate of the material, thus eliminating burrs, reducing fatigue initiation sites on the part material surface where the punch goes through the material. Also will permit forming parts of uniform thickness, impact powder titanium to form sheet, and stamp parts against flat sheet of polyurethane with punch having the shape of the part.Type: ApplicationFiled: February 19, 2013Publication date: August 21, 2014Inventor: John B.

Publication number: 20140230547Abstract: Micromachined gyroscopes, such as those based upon microelectromechanical systems (MEMS) have the potential to dominate the rate-sensor market mainly due to their small size, low power and low cost. As MEMS gyroscopes are resonant devices requiring active excitation it would be beneficial to improve the resonator Q-factor reducing the electrical drive power requirements for the excitation circuitry. Further, many prior art MEMS gyroscope designs have multiple resonances arising from design and manufacturing considerations which require additional frequency tuning and control circuitry together with the excitation/sense circuitry. It would therefore be beneficial to enhance the bandwidth of the resonators to remove the requirement for such circuitry. Further, to address the relatively large dimensions of MEMS gyroscopes it would be beneficial for the MEMS gyroscopes to be fabricated directly above the CMOS electronics thereby reducing the die dimensions and lowering per die cost.Type: ApplicationFiled: October 1, 2013Publication date: August 21, 2014Applicant: The Royal Institution for the Advancement of Learning / McGill UniversityInventors: Mourad El-Gamal, Mohannad Elsayed, Paul-Vahe Cicek, Frederic Nabki

Publication number: 20140230553Abstract: A method for monitoring movement of an element such as a cable is carried out by providing a pair of conductive elements each extending along an extent of the cable or other element to be monitored. A DC potential difference is applied between the conductive elements. The conductive elements are provided with an intervening material therebetween, which can be a continuous dielectric or can be other insulating material which varies in spacing and capacitance value along its length, such that the movement causes a change in capacitive coupling between the conductive elements at points or areas where the movement occurs so as to generate a changing voltage therebetween. The changing voltage as an amplified and filtered variable electrical signal is analyzed for monitoring the changing voltage for perturbations caused by the movement of the element.Type: ApplicationFiled: February 20, 2013Publication date: August 21, 2014Applicant: NETWORK INTEGRITY SYSTEMS, INC.Inventor: Network Integrity Systems, Inc.
