The system has a subscription management system to automatically email trainees to induce them to take and finish courses, a testing system to verify that trainees fully comprehend content and a tracking system that records the course content that trainees have taken.

Abstract: A method of improving pulse inductive metal detector sensitivity by minimizing adverse ground responses and transmitter coil transients is disclosed. The method provides a calibration mode for a typical pulsed EMI metal detector. The purpose of the calibration mode is to determine and record a nulling signal representative of the transmitter coil coupling to the receiver coil and a ground response that has no metal. The nulling signal is then used during normal operation of the metal detector by combining it with the instant receiver coil signal in a difference amplifier. The difference amplifier effectively subtracts the nulling signal from the instant signal yielding a response signal that has removed the ground response that may be present in the instant signal. The metal detector can be periodically re-calibrated. It may also be re-calibrated upon discovery of a metal target to provide the most up to date nulling signal for the ground around the metal target.

Abstract: A device and method to improve pulse inductive metal detector (MD) sensitivity uses multiple, current steps to reduce the voltage rating of electronic components. Current reduction in one implementation is done with multiple switched resistors coupled to a voltage source and connected to the transmitter coil. The current reduction in another implementation is done with multiple switched current sources that are connected to the transmitter coil and are switched inactive one by one to reduce the total current to the transmitter coil. The current is stepped down in rapid secession with a time delay between current transitions less than the time constant of the metal target under investigation.

Abstract: Provided herein is a method and system for detecting hidden dense objects in cargo containers including at least a cargo container platform with two-dimensional sensor arrays in juxtaposition therewith. The system further includes a process that estimates a weight and mass distribution data from a cargo manifest for the cargo container and available historical information about the cargo container. The historical weight and mass distribution is compared to the actual weight and mass distribution measured by the sensor arrays to detect discrepancies which will identify the tested cargo container as suspect and in need for further investigation.

Abstract: A metal detector capable of operating in both a time-domain mode and a frequency-domain mode includes a transmitter component and a receiver component. The transmitter component includes a transmitter coil that can receive both an AC and DC current source for frequency- and time-domain operation respectively. The AC signal is impressed on the DC signal such that while the transmitter coil is charging, frequency-domain sensing is occurring and when the transmitter coil is switched off, time-domain sensing is occurring. The receiver component uses a primary field bucking method to ensure that both time- and frequency-domain modes can operate with the receiver coil.

Abstract: A biocompatible surgical implant or component for a surgical implant for use in human beings and animals is described. The implant has an oxide film-forming valve metal substrate, such as titanium, titanium alloy, zirconium, or zirconium alloy, or stainless steel, or cobalt-chromium-molybdenum alloy having a surface that has been treated such that phosphorous and oxygen are incorporated into the treated surface of the implant. The surface treatment carried out on the implant includes low temperature anodic treatment of the substrate in a phosphorus-containing solution, such as a phosphate-containing solution. The anodic treatment changes or modifies the substrate surface through electrochemical reactions between the substrate, acting as an anode, and phosphate ions contained in an electrolyte solution, such as provided by an aqueous solution of phosphoric acid. The phosphorus-containing solution may be substantially calcium-free.

Abstract: A biocompatible surgical implant for use in human beings and animals. The implant has a titanium or titanium alloy substrate having a surface that has been treated with phosphates. The surface treatment on the implant includes low temperature anodic phosphation of the titanium or titanium alloy substrate.

Abstract: A press to form a composite acetabular allograft cup for use in hip replacement surgery is disclosed. The acetabular cup formed by the press comprises bone cement and cancellous bone chips. The press includes a two-piece mold for forming the acetabular cup. The mold is removable from the press and may be available in many different sizes to accommodate a range of patients. A screw-type compression means is utilized to force the acetabular cup into the desired shape. A compression gauge allows the operator to monitor the pressure applied as the acetabular cup is formed to prevent excessive crushing of cancellous bone chips. Breaking jaws are used to separate the acetabular cup from the upper portion of the mold after the bone cement has set and the acetabular cup is formed.
