Abstract: Methods and systems for operating a refrigeration system for refrigerating a product are provided. A first temperature of the refrigerant downstream of a condenser and upstream of an evaporator may be obtained. A first pressure of the refrigerant downstream of the condenser and upstream of the evaporator may be obtained. A second pressure of the refrigerant downstream of the evaporator and upstream of a compressor and/or a temperature of the product being refrigerated may be obtained. A first valve, disposed between the condenser and the evaporator, may be controlled based on the first temperature and the first pressure to maintain a pre-determined cooling set-point for the refrigeration system. A second valve of the refrigeration system, coupled to the compressor, may be controlled based on the second pressure or the temperature of the product to optimize a capacity of a compressor of the refrigeration system.

Abstract: A portable electronic device (810) for controlling a training exercise executing on a simulator of an Air Traffic Control (ATC) system, a method of doing the same using a portable electronic device (810), and a computer program product are disclosed. The device (810) is capable of wirelessly communicating with the simulator (820, 830) also suitable adapted for wireless communications. The device (810) comprises a display, a memory for storing data and one or more computer programs, a user input mechanism, and a processor. The device (810) displays on the display information about a training exercise executing on the simulator and receives inputs to control the training exercise on the simulator. The displayed information and the received inputs are communicated between the simulator and the portable electronic device (810).

Abstract: A portable electronic device (1410) for controlling a simulated aircraft in a training exercise executing in an Air Traffic Control (ATC) system having a simulator, a method of doing the same using a portable electronic device (1410), and a computer program product are disclosed. The device is capable of wirelessly communicating with the simulator (1420, 1430) also suitable adapted for wireless communications. The device (1410) comprises a display (2014), a memory (2006) for storing data and one or more computer programs, a user input mechanism (2002, 2070, 2071), and a processor (2005). The device (1410) displays on the display information about an aircraft in a training exercise executing on the simulator and receives inputs to control the aircraft in the training exercise on the simulator. The displayed information and the received inputs are communicated between the simulator and the portable electronic device (1410).

Abstract: A device temporarily positionable within an aortic arch for deflecting embolic particles released during a therapeutic or diagnostic procedure comprises a resilient frame defining an opening and a barrier disposed in the opening. The barrier has a plurality of openings, which may be pores, proportioned to allow passage of blood therethrough but to prevent passage of embolic particles. The barrier has a concave shape having a convex surface positionable in contact with a wall of an aorta to cover at least a brachiocephalic ostium. The frame may include an upstream end including a pair of lobes and an apex between the lobes, and has a generally tapered downstream end.

Abstract: An embolic deflection device includes an anchor engageable with a lumen of a branch vessel extending from an aortic arch and a deflection device, the deflection device having a first end coupled to the anchor and an elongate member extending from the deflection device. A method of deflecting embolic material away from a branch vessel extending from an aortic arch includes providing a deflection device comprising a anchor and an elongate member extending from the anchor. The anchor is engaged with a lumen of the branch vessel and positioned such that the elongate member extends within the aortic arch in proximity to ostia of at least two branch vessels. Embolic material flowing from the ascending aorta to the aortic arch is diverted by the elongate member away from the branch vessels and into the descending aorta.

Abstract: Disclosed is a propulsion system having a structural configuration that provides easy and convenient access to the interior regions of a liquid fuel tank and a hybrid rocket motor case. The system operates with a high oxidizer-to-fuel ratio and a high bulk density propellant combination that has a near uniform specific impulse over a large oxidizer-to-fuel ratio range. The system has an increased propellant mass fraction and reduced propellant residuals. This improves the performance of the hybrid propulsion system.

Abstract: A form is disclosed for cooking items, such as pancakes, in a specified shape. The form may include a sidewall defining the specified shape. One or more handles may be attached to the sidewall to facilitate handling of the form. The handles may be configured to be folded and to reduce the amount of heat conducted through them. The form may be constructed by cutting an aluminum alloy material into strips. Holes may be formed in the ends of the strips and the strips may be heated for a specified time to soften them for being formed in the desired shape. The ends of the strips may be joined together using fasteners through the holes. Forms constructed in this manner may reduce the sticking of material to the forms, and the forms may be durable to last for repeated use over a long period of time.

Abstract: A glass-ceramic material containing phosphor-doped crystallites suitable for thermal neutron detection is disclosed, the glass-ceramic material being capable of storing at least part of the energy of incident thermal neutrons, and releasing at least part of the energy by optical stimulation. A method for preparation of the glass-ceramic material is also disclosed.

Abstract: A system and method for performing phase-encoded optical Code Division Multiple Access (CDMA). A transmitter encodes digital data onto a wavelength of an optical signal using a codeword, splits the optical signal into a plurality of beams having separated frequency components, selectively phase-shifts the beams in accordance with the codeword, recombines the beams into the optical signal, and transmits the optical signal. The receiver receives the optical signal, splits the optical signal into a plurality of beams having separated frequency components, selectively phase-shifts the beams in accordance with the codeword, recombining the beams into the optical signal, and decodes the digital data from a wavelength of the optical signal using the codeword.
