Aspects of the disclosed invention relate to alignment of standard definition (SD) maps and high definition (HD maps) which may come from different sources. Responsive to input of a destination, a route to that destination may be defined, and SD map waypoints generated from that defined route. A graph may be generated from the HD map. The waypoints may be matched with nodes and edges in the graph. One or more edges may constitute a segment in the HD map. A plurality of segments are identified to match the route.

A system for obtaining air data for a vehicle comprises a laser device that emits laser light pulses, and transmit optics that transmits the light pulses into an external air volume adjacent to the vehicle. The system also includes receive optics that collects scattered portions of the light pulses from the external air volume, and a whispering gallery mode (WGM) frequency discriminator that receives the scattered portions of the light pulses from the receive optics. The WGM frequency discriminator includes at least one WGM resonator that outputs a selected portion of the light pulses at one or more optical signal frequencies via tuning the WGM resonator other than by an electro-optic effect. An optical detector samples the selected portion of the light pulses from the WGM frequency discriminator, and converts the sampled light pulses to scalar values. A processing unit receives and records the scalar values from the optical detector.

An apparatus providing for simultaneous measurement of the wind upstream and downstream of a wind turbine uses either a single LIDAR beam split into two beams, each focused upstream or downstream of the windmill, or a multiple beam LIDAR with a first beam source aimed toward the upstream direction of the wind and a second beam source aimed at the downstream direction after the wind has passed through the wind turbine. The apparatus may also use LIDAR to measure wind direction and speed by making measurements along slightly different lines of sight, or by pointing the LIDAR in different directions. Two lines of sight allow measuring wind direction in the plane defined by the two lines of sight. Three non-coplanar lines of sight provide the information necessary to determine a full 3-dimensional wind velocity vector. Further, LIDAR may also be used to measure wind speed by estimating the wind velocity using inputs from both aerosol and molecular components.

Atmospheric measurement system

One of first and second beams () of corresponding first and second light () are projected into an atmosphere () and at least one physical property of the atmosphere () is detected from the interference pattern () generated from the resulting scattered light (). The first and second beams () are selected responsive to either a detected signal-to-noise ratio (SNR) or a detected aerosol-to-molecular ratio (AMR). The wavelength () of the first light () provides for either molecular or aerosol scattering, whereas the wavelength () of the second light () provides for primarily only aerosol scattering. In accordance with a second aspect, scattered light () from one or more beams () of substantially monochromatic light () projected into the atmosphere () and received from a plurality of interaction regions () or measurement volumes () provides for determining wind power (P*) within a region of the atmosphere ().

Atmospheric measurement system and method

A magnitude and direction, or a measure responsive thereto, of a velocity (V) of a first portion () of an atmosphere () are determined from at least first and second portions of scattered light () generated along a common beam of light () within the first portion () of the atmosphere () and received along linearly independent directions at locations that are relatively remote with respect to one another, at least one of which is relatively remote from a source () of the beam of light ().

A fringe pattern from an interferometer is imaged onto a digital micromirror device containing an array of micromirrors in an associated pattern of pixel mirror rotational states that provide for sampling the circular fringe pattern in cooperation with one or more associated photodetectors, so as to provide for generate a corresponding set of associated complementary signals. A plurality of different sets of associated complementary signals generated for a corresponding plurality of mutually independent associated patterns of pixel mirror rotational states are used to determine at least one metric associated with the circular fringe pattern.

Light scattered by a portion of a fluid medium illuminated by a beam of substantially monochromatic light is received within a field-of-view nominally along an axis oriented in a different direction relative to the beam and processed by an interferometer to generate a corresponding fringe pattern that is detected and processed to generate at least one measure of the fluid medium at a plurality of different ranges.

A vehicle heating and cooling system having a first coolant loop selectively connecting an engine cooling system with a heater core or a first coolant/refrigerant heat exchanger, a second coolant loop connecting a second coolant/refrigerant heat exchanger and the heater core to warm a passenger compartment of the vehicle. The system also includes a refrigerant loop that provides for conventional cooling of the passenger compartment of the vehicle, as well as operating as a heat pump, together with the coolant loops, to provide heat to the vehicle passenger compartment.
