A method (10) of obtaining acoustical measurements of an individual ear that are compensated for errors caused by ear canal resonances.

A rotatable forming apparatus and a method for modifying a shape of a container. The rotatable forming apparatus includes a frame and a forming turret assembly. The forming turret assembly includes a drive shaft, a fixed turret portion, a turret starwheel, an axially moveable turret portion and forming ram assemblies. The forming ram assemblies extend around and connect to the axially movable turret portion. Each of the forming ram assemblies includes cam followers, a forming die, a knockout tooling device and a drive cylinder. The cam followers are configured to follow the cam as the forming ram assemblies rotate around the stationary cam. The forming die is operatively connected to the cam followers such that the forming die moves in the vertical direction while following the cam. The drive cylinder causes axial movement of the knockout tooling device and is configured to operate independently of the forming die.

An exemplary elevator brake device includes at least one braking component that is movable between a disengaged position and a fully engaged position. An actuator selectively moves from a ready position to urge the braking component to move from the disengaged position toward the fully engaged position. A reset component moves responsive to movement of the braking component toward the fully engaged position. The reset component causes the actuator to move back toward the ready position before the braking component reaches the fully engaged position.

A capacitor-over-bitline structure includes a bottom electrode that has an open vessel form factor. The bottom-electrode form factor includes a floor, rectilinear sidewalls, and a rim that defines the topmost feature. A capacitor dielectric film contacts and covers the floor, the sidewalls, and the rim. A top electrode has a convex form factor that complements the concave bottom-electrode form factor. A process of forming the capacitor-over-bitline structure by spinning on a reflowable sacrificial material such as an oxide that covers both logic and memory portions of a semiconductive device, followed by a polish-back process and a recessing etch of the bottom electrode.

A vehicular collision avoidance system includes a sensor mounted on a vehicle, wherein the senor is operative to measure the distance between an overhead obstacle ahead of the vehicle and the sensor; a processor connected to the sensor; means for determining a reference height which is the height above ground level at which the sensor is mounted on the vehicle, and wherein the reference height is entered into the processor; means for determining the height of the tallest portion of the vehicle above ground level, wherein the height of the tallest portion of the vehicle is also entered into the processor; and wherein the processor adds the reference height to the distance between the obstacle and the sensor to determine a measured height of the obstacle. The processor produces an alarm if the measured height of the obstacle is less than the height of the tallest portion of the vehicle.

A variable flow resistance system for use with a subterranean well can include a structure which displaces in response to a flow of a fluid composition, whereby a resistance to the flow of the fluid composition changes in response to a change in a ratio of desired to undesired fluid in the fluid composition. Another system can include a structure which rotates in response to flow of a fluid composition, and a fluid switch which deflects the fluid composition relative to at least two flow paths. A method of variably resisting flow in a subterranean well can include a structure displacing in response to a flow of a fluid composition, and a resistance to the flow of the fluid composition changing in response to a ratio of desired to undesired fluid in the fluid composition changing. Swellable materials and airfoils may be used in variable flow resistance systems.

A fluid discrimination system can include a fluid discriminator which selects through which of multiple outlet flow paths a fluid composition flows, the selection being based on a direction of flow of the fluid composition through the discriminator, and the direction being dependent on a fluid type in the fluid composition. Another fluid discriminator can include a structure which displaces in response to a fluid composition flow, whereby an outlet flow path of the fluid composition changes in response to a change in a ratio of fluids in the fluid composition. A method of discriminating between fluids can include providing a fluid discriminator which selects through which of multiple outlet flow paths a fluid composition flows in the well, the selection being based on a direction of flow of the fluid composition through the discriminator, and the direction being dependent on a ratio of the fluids in the fluid composition.

This invention relates generally to tires having multiple carcasses that wrap around multiple bead cores on a single side of the tire, and, more specifically, to a tire that has a bead core locking insert that eliminates a pullout step for one of the carcass plies or bands during fabrication, This step includes wrapping one of the plies or bands completely around said multiple bead cores that are found on a single side of the tire. In certain embodiments, the tire is an aviation tire that has bands of multiple plies that are wrapped about multiple bead cores found on each side of the tire. The bead core locking insert is found below the multiple bead cores found on each side of the tire and is adjacent to the bands that wrap around the inside and outside head cores, thereby locking these beads and associated bands together.

Technologies are generally described for mitigating or eliminating the effects from data loss. In an example, a data transmission system may be configured to send a data stream to a receiving device over a first data transmission path. The data transmission system may also be configured to send data representing key frames included in the data stream to a redundancy transmission device over a second data transmission path. The redundancy transmission device may be configured to transmit key frames to the receiving device in response to a loss of data.

A method and network node for managing a relay node that is moving relative to a source network node, the method ensuring a target network node is capable of supporting the relay node; sending a handover request of a relay node from the source network node to the target network node; and establishing an interface between the relay node and the target network node.
