Publication number: 20130293997Abstract: An EMP/HEMP protection device for protecting equipment from electromagnetic pulses. The protection device includes a housing defining a cavity therein and separated into two chambers, a dirty chamber for propagation of signals before filtering of electromagnetic interference, and a clean chamber, isolated from the dirty chamber, for propagation of signals after filtering. A rigid-flex printed circuit board (PCB) is disposed in the cavity for facilitating electrical connections between the chambers. Surface mount electrical components for EMP/HEMP protection are coupled with the rigid-flex PCB. Power and/or data signals are transferred from the dirty chamber to the clean chamber though a wave guide below cutoff (WBC). The WBC is formed from opposing electrical ground planes within a center PCB of the rigid-flex PCB. An electrically conductive and weather sealing gasket is disposed in the cavity of the housing for further EMI isolation.Type: ApplicationFiled: May 3, 2013Publication date: November 7, 2013Applicant: Transtector Systems, Inc.Inventors: Trevor O. Tollefsbol, Eric Nguyen

Patent number: 8287503Abstract: A balloon trocar includes a cannula assembly including a cannula and an outer sleeve fitting over the cannula. The distal end of the outer sleeve is proximal to the distal end of the cannula. A balloon is coupled to a distal portion of the sleeve and a distal portion of the cannula. The outer surface of the cannula includes a plurality of longitudinal channels for transmitting gas or fluid to the balloon. A bolster having a gel pad at its distal portion is slidably mounted to the cannula assembly and may be locked in a desired position. In use, the trocar is inserted into an incision through a body wall and into a body cavity. The balloon is inflated and the cannula assembly pulled proximally against the incision while the bolster is slid distally to the body wall and locked in place to seal the incision with the compressed balloon.Type: GrantFiled: March 8, 2007Date of Patent: October 16, 2012Assignee: Applied Medical Resources CorporationInventors: Jeremy J.
