Each c-shell unit has at least two sled-less memory bays and the sled-less memory bays are positioned vertically relative to each other. Each of the sled-less memory bays receives a memory device. A PCB is vertically mounted to a corresponding c-shell unit. The control logic controls access to and from the memory devices so that it manages storing data to the memory devices and retrieving data from the memory devices. Each PCB comprises traces to route signals between the control logic and the memory devices.

Abstract: A system and method use an inverse square root function (ISQR) function, in part, to compand and decompand signals. A system includes a companding processor and a transmitter. The companding processor compands input signals into companded signals using a compander function, C{x(n)}. The compander function compands the input signals based, at least in part, on an inverse square root (ISQR) function over at least a portion of a signal amplitude probability density function. The transmitter then transmits the companded signals as electromagnetic wave signals.

Abstract: A fiber laser having a thermal controller operatively connected to one or more fiber Bragg gratings is provided. The thermal controller does not impart much or imparts very little mechanical stress or strain to the optical fiber in which the FBGs reside because such forces can alter the FBG performance. Rather, the thermal controller utilizes a thermally conductive semi-solid or non-Newtonian fluid to submerge/suspend a portion of the optical fiber in which FBG resides. Temperature control logic controls whether a thermoelectric heater and cooler should be directed to increase or decrease its temperature. The thermoelectric heater and cooler imparts or removes thermal energy from the FBG to efficiently control its performance without the application of mechanical stress. The fiber laser having a thermal controller generally is able to increase laser output power greater than two times the amount of output power of a similarly fabricated fiber laser free of the thermal controller(s).

Abstract: A system and method for mounting a device to a piece of equipment is presented, and may include a handheld inertial measurement unit (IMU), a computer logic and a mounting interface. The piece of equipment may have a line replaceable unit (LRU) mount that allows a new LRU to be mounted thereon. The mounting interface may be mounted to a LRU mount. The handheld IMU may determine position data with respect to the LRU mount and the piece of equipment. The computer logic may be configured to calculate a positional error value based on the position data to indicate to a user whether corrections need to be made regarding how the new LRU is mounted to the LRU mount before the new LRU is mounted to the LRU mount or whether the new LRU can be mounted to the LRU mount without any corrections.

Abstract: What is provided is recording capability for each of the modules utilized by the first responders and other personnel within the area of the incident, with the stored information at each of the first responders' modules being read out through the ad hoc network, where it can be uploaded to storage. The stored information can be displayed at an incident commander work station in real time to give the incident commander a realistic view of the timeline and the severity of the incident, as well as the response. The use of the ad hoc network permits offloading stored information from each of the first responders' modules so as to free up storage within the modules. By providing storage at every node of the ad hoc network, one has access to a timeline of the actions at the incident as well as redundancy, which enhances the memories and observational skills of the first responders.

Abstract: A system and method for tracking aircraft, helicopters and/or other objects at an airfield using acoustics of the aircraft, helicopters and/or other objects. A method receives first acoustical data at a first sensor and second acoustical data is also received at a second sensor. The first and second sensors may be carried by a first structurally supportive body member. Based at least in part on the first acoustical data and the second acoustical data a range and a bearing of the aircraft is determined from a predetermined location at the airfield. The range and bearing can be determined by using a beam forming algorithm. Based on the range and the bearing, the method displays the location the aircraft on a display.

Abstract: A fiber optic geometric isolator is disclosed which is inserted between two cascaded, high-power fiber optic lasers and, in conjunction with a cladding mode stripper, provides improved optical Isolation between the two fiber optic lasers while maintaining highly-efficient laser operation. The isolator achieves this without the need for electromagnetic isolation between the two cascaded lasers. The isolator is an optical fiber designed to operate as a monolithic, continuous waveguide to enable a specific mode-coupling condition that converts the light of a first laser to that of a second, cascaded laser, with the light moving from the core of the first laser to both the core and the cladding of the second laser.
