Abstract: A method for monitoring a battery while the battery is connected to a load has been developed. The method includes measuring a first current level flowing through the battery to the load and a first voltage level of the battery at a first time, generating an estimated open cell voltage (OCV) of the battery at the first time based on the first current level, the first voltage level, and a predetermined model of the battery, identifying a first excitation level of the battery at the first time based on the first voltage level, the first current level and a cost optimization process, and identifying at least one of a state of charge (SoC) and state of health (SoH) of the battery using the estimated OCV only in response to the first excitation level being below a predetermined threshold.

Abstract: A method of monitoring a battery with a controller identifies appropriate times for estimating a state of the battery. The method includes identifying a persistence of excitation in the battery, identifying a magnitude of an electrical current that is supplied to the battery, and performing a state estimation process for the battery only in response to the identified persistence of excitation exceeding a first predetermined threshold and the identified magnitude of the electrical current exceeding a second predetermined threshold.

Abstract: A method for predicting and correcting an impending misfire in a homogeneous charge compression ignition (HCCI) engine includes: modeling HCCI engine operation in a nominal, steady-state operating region and in unstable operating regions bordering the steady-state operating region, using a zero-dimensional model; predicting an occurrence of an engine misfire based on the modeling of the HCCI engine operation; and providing a remedial corrective measure when an engine misfire is predicted. The remedial corrective measure includes one of: (a) late injection to avoid full combustion during a trapping cycle, and a reduction in amount of injected fuel to account for residual fuel of the previous cycle; or (b) earlier exhaust valve closing to trigger combustion of residual fuel within the trapping cycle, and a later injection and reduction of injected fuel to account for residual fuel of the previous cycle.

Abstract: An image compositing and compression method based on the creation and processing of parallax differences in motion photography. A parallax scanning MOE lens creates discrete parallax differences in the objects in the recorded scene that are perceived by the viewer as enhanced texture and depth when displayed. Using parallax differences in a captured scene, a computer can detect objects for the purpose of creating image compositing mattes. This method allows matte passes to be filmed on location at the time of principal photography, thereby saving costly additional blue/green stage production shoot days associated with traveling matte techniques. In addition, because the mattes are based on parallax scan differences in the recorded scene and not on a uniform color and luminance process, certain conflicting scene subject colors will not have to be avoided. Also, because the matte scenes are recorded on location, the lighting in each of the various elements matches in the final composited image.

Abstract: A method is provided for generating an autostereoscopic display. The method includes acquiring a first parallax image and at least one other parallax image. At least a portion of the first parallax image may be aligned with a corresponding portion of the at least one other parallax image. Alternating views of the first parallax image and the at least one other parallax image may be displayed.

Abstract: A method is provided for real time control and manipulation of a moving imaging system lens's (prime, close-up, zoom, or anamorphic) depth of field. A computer control system is programed to perform a coordinated adjustment of a closed loop lens iris (aperture) and the shutter angle of a motion picture camera. The iris of the lens is reduced in size while simultaneously increasing the motion picture camera shutter angle an equal exposure (light transmission) amount, therefore, increasing the apparent image depth of field without a perceivable luminance shift. The image depth of field can be reduced by performing the above operation in reverse.
