Abstract: Systems and methods for improving an end-to-end (E2E) vehicle simulation in replicating a real-world driving scene based on a continuous feedback loop are provided. For example, a method includes receiving first data collected from a real-world driving scene, the first data associated with the real-world driving scene and a performance of a real-world vehicle in the real-world driving scene; and adjusting, for a current iteration, a parameter associated with an E2E vehicle simulation that simulates operations of a simulated vehicle driving in a simulated driving scene, wherein the adjustment is based on a fidelity value of the E2E vehicle simulation in a previous iteration, and the fidelity value is based on a comparison between second data collected from the E2E simulation in the previous iteration and the first data.

Abstract: Systems and methods for evaluating a fidelity of a simulation in replicating a real-world driving scene are provided. A computer-implemented system including one or more non-transitory computer-readable media storing instructions, when executed by one or more processing units, cause the one or more processing units to perform operations including receiving first data collected from a reference driving scene, the first data associated with the reference driving scene and a driving behavior of a first vehicle in the reference driving scene; receiving second data collected from a driving simulation that generates a simulated driving scene and operations of a second vehicle in the simulated driving scene, wherein the simulated driving scene is a simulation of the reference driving scene; and determining a fidelity of the driving simulation based on a comparison between the first data and the second data.

Abstract: Embodiments are related to systems and methods for data determining information about a subject, and more particularly to systems and methods for utilizing and distributing information related to measurements of a human subject.

Abstract: An excavator attachment apparatus includes a first fork configured to be removably attached to the distal end of a dipper arm of an excavator, wherein the first fork has an inner side and an outer side. The excavator attachment apparatus further includes a power saw, wherein the proximal end of the power saw is rotatably coupled to the outer side of the first fork. The excavator attachment apparatus further includes a hydraulic cylinder configured to rotate the power saw when the hydraulic cylinder is actuated. The excavator attachment apparatus further includes a second fork configured to be removably attached to the bucket link and distal end of the dipper arm of the excavator and actuated by the hydraulic bucket cylinder of an excavator to alternate between an open position and a closed position relative to the first fork.

Abstract: An example method of decontaminating a fuel reactant stream for a fuel cell flows the fuel reactant stream through a fluidized ammonia dissolving media, while simultaneously flowing water through the fluidized ammonia dissolving media to separate contaminants from the fuel reactant stream into a separated contaminant and water stream. The separated contaminant and water stream from the fluidized bed is accumulated within an accumulator, circulated through a water-control loop, and decontaminated by flowing the stream through an ion exchange bed secured in fluid communication with the water-control loop. A decontaminated water stream from the ion exchange bed is circulated back through the ammonia dissolving media. A temperature of the fuel reactant stream is controlled upstream of the fuel reactant stream entering the separator scrubber to produce a predetermined temperature of the fuel reactant stream passing through the separator scrubber.

Abstract: An apparatus includes an electric motor including a rotor and a stator, and a compression device including a compression chamber and a compression mechanism. The compression chamber is within either the rotor or the stator of the electric motor.

Abstract: The compressor fittings, both suction and discharge, of a compressor can have braze rings positioned inside of the fittings as part of the compressor assembly. The braze ring can then be used by an installer to connect the compressor to corresponding suction and discharge lines of a system. The installer can insert the system tube or connection into the fitting and apply a torch until braze material can be seen exiting the joint around the system tube, which indicates the tube has been connected.

Abstract: A motor cap has a plurality of holes in the top of the cap for the entry of refrigerant into the suction plenum. The holes are sized and located to create a tortuous path for a stream of refrigerant to enter the compression chamber. The refrigerant stream is broken into multiple streams and any liquid refrigerant is encouraged to flash to vapor. Any oil that is brought from the sump at startup by boiling liquid refrigerant is likewise encouraged to remain on the motor cap and drain back to the sump while the liquid refrigerant flashes to vapor.

Abstract: A compressor can have one or more of a suction fitting with integral louvers and a screen, a motor cap with a plurality of holes in the top surface of the motor cap to permit refrigerant to enter a suction plenum, a filter positioned over the plurality of holes in the motor cap, a filter for the cage bearing and a braze ring installed in one or more of the compressor fittings.

Abstract: A suction fitting for a compressor can include screens, filters, and direction control louvers to both filter out particulates and direct higher mass liquid refrigerant downward away from the inlet to the compression chamber. Alternatively, a mesh filter can be place over the opening(s) to the suction plenum to prevent debris and contaminants from entering the suction plenum.

Abstract: A comfortable, smooth, and sanitary cover is provided for a “U” shaped face cradle of a massage table or chair, the face cradle having a central portion and two arms extending from the central portion. The cover is formed of a fabric panel having a medial region and pair of lobes extending from the medial region and defining a notch between them. Each of the lobes is provided with a pocket and the medial region is provided with weights attached on an outer periphery. Each of the pockets is configured for partially receiving an arm of the face cradle. The cover may be draped onto the face cradle, with the medial region adjacent the central portion, with pockets receiving the arms, and with weights being suspended from the outer periphery, so as to overhang the central portion of the face cradle and to smoothly spread the cover over the surface of the face cradle. The cover contacts the face of an individual resting on the face cradle, during a massage.

Abstract: A multi-function separator provides a coalescing section for removal of entrained impurities in a process stream; an adsorbent section for removal of vapor contaminants; and a filter section for removal of particulate impurities. A process stream flows into longitudinal hollow centers of porous coalescer robes and radially out; through holes in a baffle; into an adsorbent section; through a redistribution baffle; into filters; and out through another redistribution baffle. The multi-function separator is designed so that the process stream flows transverse to the longitude of an elongate vessel. The fluid velocity within the coalescer section is equal throughout, so that localized high-velocity areas are avoided, thus preventing re-entrainment of a coalesced contaminant.
