Abstract: A plug-compatible interface between a car and its human and/or computer driver makes both car and driver a “black box”, or abstraction, to the other. The two black boxes can then be developed and built independently before being integrated together only at the final stage. Designers on both the car and driver sides of the interface need design only to the interface and need not worry about how things are done on the other side of it. When cars and computer drivers are built to interact over a plug-compatible interface, any computer driver works with any car. If a computer driver becomes outdated, it can be updated or replaced much more quickly and cheaply than replacing the entire car.

Abstract: This application relates to the production, storage, and controlled release of hydrogen for use in the hydrogen economy. More specifically, it relates to a novel electrolysis system design that utilizes electrolysis of ionized vapors and gasses to produce and store hydrogen in a hydrogen host material and the capability to reverse the electrolysis potential to provide safe, controlled hydrogen release.

Abstract: Our car operating system allows a car's driver to control—using abstract direction and speed commands—the car's devices that make the car move. The car operating system uses information like the current state of the car's devices to process those high-level abstract commands and generate device-specific commands at a lower level of abstraction to send to the car devices that will implement the driver's commands. The car operating system sits between the driver of the car (which may be a human or an automated driving program) and the car's devices, much like a computer operating system sits between the user of a computer (which may be a human or an application program) and the computer's devices. The car operating system performs two functions: (1) Provides an abstract machine that allows the car's driver to use more powerful abstract commands rather than more primitive device-level commands. (2) Manages the car's resources so that the car's driver does not have to control each device directly.

Abstract: Disclosed is a domain- specific data analysis system for analyzing a source database within a domain of expertise. By means of a graphical interface and a set of generic database operators, a user may construct a domain schema which is a mapping between the source database and a set of domain-specific data operators and domain-specific visualizations. The domain schema may then be used in subsequent domain-specific analyses of the source database. Even though the source database may have naming and data structure variations, domain-specific queries may be performed by users with minimal programming skills.

Abstract: Disclosed is an electronic gimbal with camera and mounting configuration. The gimbal can include an inertial measurement unit which can sense the orientation of the camera and three electronic motors which can manipulate the orientation of the camera. The gimbal can be removably coupled to a variety of mount platforms, such as an aerial vehicle, a handheld grip, or a rotating platform. Moreover, a camera can be removably coupled to the gimbal and can be held in a removable camera frame. Also disclosed is a system for allowing the platform, to which the gimbal is mounted, to control settings of the camera or to trigger actions on the camera, such as taking a picture, or initiating the recording of a video. The gimbal can also provide a connection between the camera and the mount platform, such that the mount platform receives images and video content from the camera.

Abstract: A compression roller device includes markers on roller heads for pressure-rolling over a substrate to form visual indicia that the substrate has been properly pressure-rolled. In example embodiments, there are two roller heads that each have a set of markers and that are spaced-apart with a handle center-mounted between them. In this way, the roller heads have free/unobstructed outer/opposite edges so they can be positioned closely against an obstructing surface or element for rolling substrates in tight spots with limited clearance. Also, the recess defined between the inner/facing edges of the roller heads provides clearance for rolling over any protruding fasteners securing the substrate in place. Further, the spaced-apart marker sets provide for marking the visual indicia on both sides of a seam/joint between two adjacent panels in a panel-and-tape system to show that both longitudinal side portions of the tape have been pressure-rolled.

Abstract: In some implementations, a method for validating an acoustic bond-log tool includes having a test fixture including a wellbore casing emulating tubing. An outer tubing emulates a well formation and forms a perimeter of an annulus surrounding the wellbore casing emulating tubing. The wellbore casing tubing is configured with a stepped outer surface emulating different wellbore casing sidewall thicknesses. A dividing structure is coupled in the axial direction to the outer surface of the wellbore casing emulating tubing and to the inner surface of the outer tubing to radially subdivide the annulus into a plurality of hermetically sealable sample sections. Each sample section contains a sample of a material having a known acoustic impedance. The acoustic bond-log tool is validated by comparing a bond-log tool measurement of the acoustic impedance of each sample in a particular sample section to the known acoustic impedance of the sample.

Abstract: An electric car draws lots of power that needs to be on board the moving vehicle. An adaptive power supply can combine a variety of sources of electrical energy—which may include an internal combustion engine—and use those different sources to efficiently produce the electrical power required. An adaptive power supply provides optimal performance by sensing changing conditions, often hundreds of times per second, and then adapting itself to those conditions in order to optimize efficiency at each particular instant during a car's operation. Those conditions may include changes in user inputs, machine operating conditions, and machine operating parameters. Having multiple sources of electrical power allows effective control of more independent power parameters, enabling greater freedom to adapt to optimize efficiency. That gives adaptive power supplies that are cheaper, smaller, lighter, more powerful, and more efficient than conventional designs.
