Abstract: A rail gear assembly includes a base, a first wheel arm, and a second wheel arm. The rail gear assembly may include actuators that move the first wheel arm and second wheel arm between retracted positions and extended positions. The actuators may permit adjustment of the first wheel arm and the second wheel arm in their respective extended positions such that a net adjustment of the first wheel arm and the second wheel arm with respect to the base is approximately zero.

Abstract: A rail gear assembly includes a base, a first wheel arm, and a second wheel arm. The first wheel arm may have a first end pivotally coupled to the base at a first arm connection and may have a second end rotatably connected to a first wheel by a first axle. The second wheel arm may have a first end pivotally coupled to the base at a second arm connection and a second end rotatably connected to a second wheel by a second axle. The second axle may be independent of the first axle. The rail gear assembly may include actuators that move the first wheel arm and second wheel arm between retracted positions and extended positions. The actuators may permit adjustment of the first wheel arm and the second wheel arm in their respective extended positions such that a net adjustment of the first wheel arm and the second wheel arm with respect to the base is approximately zero.

Abstract: A motion compensation system includes a plurality of RF transmitters, a plurality of direction of arrival sensors, and a positioning table which together are usable to compensate for intrafraction motion of a patient during a medical procedure. The positioning table may be a secondary table arranged next to or above a primary table such as a radiotherapy couch, allowing for repositioning of part of patient such as the head and neck relative to a remainder of the body. The motion compensation system employs a direction of arrival sensor that includes rotating antenna elements in a configuration that improves the ease and accuracy of signal processing and analysis to identify the position of an RF transmitter affixed to a patient. The repositioning table has six degrees of freedom and is safe for use in imaging and radiation intensive environments.

Abstract: A pressure sensor is provided, the sensor comprising an inlet for connecting to a body of gas; a diaphragm assembly comprising a first diaphragm and a second diaphragm, the first and second diaphragms defining a chamber therebetween, the chamber being connected to the inlet; a first transducer responsive to movement of the first diaphragm and operable to produce a first electrical signal in response to the same; and a second transducer responsive to movement of the second diaphragm and operable to produce a second electrical signal in response to the same; and an amplifier disposed in the chamber of the diaphragm assembly and connected to the first and second transducers to receive the first and second electrical signals therefrom.

Abstract: Rules, applied to deny authorization of likely fraudulent transactions, are derived from a modified Patient Rule Induction Method algorithm that uses a target variable and a data set of past transactions each associated with a plurality of input variables and a hyper-rectangle enclosing a multi-dimensional space defined by a representation of the input variable values as points within the multi-dimensional space. While a count of the points within the hyper-rectangle is greater than a minimum support parameter, a first plurality of points proximal to edges of the hyper-rectangle are removed, where each such removing maximizes a mean value of the target variable, and then, while the mean value remains maximized, a second plurality of points proximal to the edges is added, where each adding maximizes or maintains the mean value. The hyper-rectangle is bounded within a minimum bounding box that defines the rules.

Abstract: A system, apparatus, and method for reducing fraud in payment transactions by identifying a potential point of compromise (POC) that may lead to subsequent fraudulent transactions, or confirming that a suspected point of compromise is in fact responsible for a security breach leading to fraudulent payment transactions. The invention is also directed to a system, apparatus, and method for identifying data or transaction characteristics that may be used to most effectively identify a point of compromise in a payment transaction system.

Abstract: An enclosure for use in a cable management system includes an outer shell having a generally rectangular shape and defining an interior space, the outer shell including a bottom panel, a top panel and first and second sidewalls. A first reversible mounting bracket is provided for connection to the bottom panel, and a second mounting bracket is provided for connection to the top panel. The first and second mounting brackets can include means for supporting cable management devices. The mounting brackets can each include a generally L-shaped member having a first portion positioned adjacent to the top or bottom panel, and a second section positioned substantially perpendicular to the top or bottom panel. The means for supporting cable management devices can include a master plate that can be mounted between the brackets. The master plate can define one or more openings for attachment of the cable management devices.
