US Classification:

123266, 123273

Abstract:

An apparatus is disclosed including a first end defining an inner passage along a first inner surface of the first end, where the inner passage has threads structured to receive a spark plug. The apparatus further includes a second end opposite the first end and extending into a combustion chamber of a cylinder, the second end defining a pre-combustion chamber along a second inner surface and threads on an outer surface structured to thread into a spark plug hole in a cylinder head, which may be an enlarged spark plug hole. The second end includes holes that fluidly couple the pre-combustion chamber of the second end with the combustion chamber of the cylinder.

US Classification:

60278

Abstract:

An internal combustion engine system includes a spark-ignited internal combustion engine powered by a gaseous fuel. The engine system also includes an air intake in air providing communication with the internal combustion engine. Further, the engine system includes an exhaust system in exhaust gas receiving communication with the internal combustion engine. The exhaust system includes a methane oxidation catalyst through which at least a portion of the exhaust gas flows and an exhaust gas recirculation line in exhaust gas providing communication with the air intake.

17/897403

Inventors:

- Fremont CA, US
Daniel Aaron Mohr - Saint Paul MN, US

International Classification:

G01S 7/481
G01S 17/89
G02B 5/18

Abstract:

Method and apparatus for generating pulses in a light detection and ranging (LiDAR) system. In some embodiments, a resonance chamber is provided to recirculate electromagnetic radiation from a light source between a base mirror and an active laminated structure characterized as a Bragg grating structure and having interleaved passive and active layers. A Q-switch control circuit applies a voltage profile to the active layers to transition the active laminated structure between a charging state in which the electromagnetic radiation recirculates within the resonance chamber and a release state in which the electromagnetic radiation is transmitted through the active laminated structure as an emitted light pulse. The passive layers may be formed of a dielectric material. The active layers may be formed of a metal material such but not limited to Indium Tin Oxide (ITO), Lithium Niobate (LiNbO3), Barium Titanate (BaTiO3), doped Silicon (Si), or doped Germanium (Ge).

International Classification:

G01S 7/481
G01S 17/89
G01S 17/10
G01S 7/4861

Abstract:

Method and apparatus for enhancing resolution in a light detection and ranging (LiDAR) system. In some embodiments, an emitter is used to emit light pulses at a first resolution within a baseline, first field of view (FoV). A specially configured optical element, such as a refractive optical lens, is activated responsive to an input signal to direct at least a portion of the emitted light pulses to an area of interest characterized as a second FoV within the first FoV. The second FoV is provided with a higher, second resolution. In some cases, all of the light pulses are directed through the optical element to the second FoV. In other cases, the first FoV continues to be scanned at a reduced resolution. A rotatable polygon, micromirrors and/or solid state array mechanisms can be used to divert the pulses to the optical element.

International Classification:

G01S 7/497
G01S 17/89
G01S 17/10

Abstract:

A light detection and ranging system can have a light source coupled to a polygon reflector having a plurality of facets. A controller can be connected to the light source and directed to generate and execute a calibration strategy that alters an orientation of the light source in response to identification of a position of at least one facet of the plurality of facets.

International Classification:

G01S 17/86
G01S 7/493
G01S 17/32

Abstract:

A light detection and ranging system can have an optical sensor connected to an alias module. The optical sensor can have an emitter along with a first detector and a second detector. The alias module may be configured to characterize a detected return photon as an alias. The configuration of the detectors allows light beam walk to be corrected by the alias module.

International Classification:

G02B 27/30
G01S 17/10
G01S 7/487
G01S 7/481

Abstract:

Apparatus for collimating light in a light detection and ranging (LiDAR) system. A light source outputs a light beam for transmission to a target, such as a multi-mode source which generates an elongated beam with a higher diverging fast axis and a lower diverging slow axis. A refractive lens assembly collimates the light beam using a concave first cylindrical surface extending in facing relation toward the light source along the fast axis and a convex, second cylindrical surface facing away from the light source and extending along the slow axis orthogonal to the first cylindrical surface. A second refractive lens assembly distal from and orthogonal to the second cylindrical surface has a convex third cylindrical surface to further collimate the light beam along the fast axis. The elongated beam may diverge at a greater angle along the fast axis as compared to the slow axis.
