Abstract:
Systems and methods for providing incentives for the public to travel during time windows and routes that help alleviate traffic congestion. The systems described herein include at least two components: a computer server software system that includes various algorithms and database sub-systems; and a mobile device application. Generally, a user may enter an origin, destination, and preferred time of travel for an intended trip into the mobile device application, which transmits the information to a remote server. The server computes a route for the trip and provides the user with available incentives for traveling the route at one or more departure time windows. The user's mobile device transmits GPS data to the server, which allows the server to verify whether the user has traveled the route during the specified time window. If so, the server then provides the incentive to the user via the user's mobile device or through email.
Abstract:
An illumination system is disclosed for providing dual-excitation wavelength illumination for non-linear optical microscopy and micro-spectroscopy. The illumination system includes a laser system, an optical splitting means, a frequency shifting system, and a picosecond amplifier system. The laser system includes a laser for providing a first train of pulses at a center optical frequency ω1. The optical splitting means divides the first train of pulses at the center optical frequency ω1 into two trains of pulses. The frequency shifting system shifts the optical frequency of one of the two trains of pulses to provide a frequency shifted train of pulses. The picosecond amplifier system amplifies the frequency shifted train of pulses to provide an amplified frequency-shifted train of pulses having a pulse duration of at least 0.5 picoseconds.

Abstract:
Provided herein are devices and methods for generating microfluidic gradients, including an array of unique microfluidic gradients within an array of microchannels. Fluids within conduits are mixed in an intersection region to generate a mixed flow stream in a source reservoir channel that provides a gradient that varies with axial distance from the intersection region. Microchannels having an inlet connected to the source reservoir channel are configured to provide a microfluidic gradient in the microchannel. An outlet end of the microchannel is connected to a sink reservoir channel. By varying the ratio of fluid flow rates from the fluid conduits, the microchannel gradients are tuned. In this manner, a large number of unique gradients or array of microfluidic gradients is provided, wherein the gradient can be any number of physical or chemical parameters, including concentrations and physical fluid properties.
Abstract:
An apparatus for obtaining energy from a polychromatic energy source that emits radiation in a first and a second wavelength band comprises a reflector or an energy receiver having an aperture therein; and a holographic lens that diffracts and focuses the radiation within the first wavelength band from the energy source through said aperture towards a first energy receiver, and transmits the radiation within the second wavelength band from the energy source to the reflector or energy receiver. If a reflector is used, the reflector reflects the radiation transmitted by the holographic lens towards a second energy receiver.

The present invention relates generally to a head-mounted projection display, and more particularly, but not exclusively to a polarized head-mounted projection display including a light engine and a compact, high-performance projection lens for use with reflective microdisplays.
Abstract:
A storage device for the storage and retrieval of arbitrary sequences of binary information provides areal densities exceeding terabytes per square centimeter (TB/cm2) and even petabytes per square centimeter (PB/cm2) in a 3D configuration. The information is encoded in long strands of biological or non-biological molecules such as artificial DNA, RNA or other synthetic molecules that form a macromolecule. The strands are written in-situ and, in some cases synthesized in-situ, transported to and from read and write stations and memory locations on the device. The data is read out by detecting individual bases or collection of bases directly from the strand.

Abstract:
A high performance, low-cost automotive radar is designed by mounting receivers around a 3D printed Luneburg lens. With this configuration, the antenna radiation pattern is maintained for all angles, (which means no beam deformation). Further, the present radar is capable of performing detection at all azimuth and elevation angles with high angle resolution and broadband operation. The radar adaptively adjusts its spatial sensing pattern, sweeping frequency band, pulse repetition frequency and coherent processing interval according to the environment. This is accomplished by initially performing a rough scan, which updates sensing results via a narrow bandwidth waveform and wide beam scanning. When interested objects are identified, a high-resolution detailed scan is performed in a specific region of interest. In this way, a much more effective detection can be obtained. Moreover, a method of mitigating interference of the 3D printed Luneburg lens based radar and a method of improving the angle resolution using a lens based MIMO approach is disclosed.
Abstract:
A closed-circuit heliox delivery system and methods for alleviating symptoms of COPD and related disorders are provided. The system is self-monitoring and can be used outside of a hospital environment. The system contains a gas supply fluidly connected to a breathing circuit. The breathing circuit contains an upper airway device, such as a mask. The system contains a sensor(s) and controller. The sensors measure parameters in the system, the ambient environment, or related to the physiological state of the user. The controller can adjust the system to maintain parameters within the device, i.e. pressure, temperature, humidity, within predetermined ranges. The controller can adjust the system to maintain a target physiological state of the user, i.e. target blood oxygen levels or Work of Breathing (WOB).
Abstract:
A system and method for controlling hypersonic boundary layer transition for a hypersonic flight vehicle are disclosed. The reduction or elimination of hot streaks that naturally occurs in the boundary layer transition process during hypersonic flight is achieved by utilizing various techniques. One such technique utilizes roughness elements to counteract streak development. The techniques for reducing or eliminating the streaks are tailored such that the nonlinear stages of transition are profoundly altered. This results in significant drag reduction, and consequently an increase in range of the vehicle, and also a reduction of the weight penalty due to the Thermal Protection Systems (TPS) as less protective material would be required, thus allowing for an increased payload and/or range of the vehicle.
