Method and apparatus for streaming force values to a force feedback device

A method and apparatus for shaping force signals for a force feedback device. A source wave is provided and is defined by a set of control parameters (including a steady state magnitude, a frequency value and a duration value) and modified by a set of impulse parameters (including an impulse magnitude, and a settle time representing a time required for the impulse magnitude to change to the steady-state magnitude). Optionally, application parameters specifying a direction of force signal and trigger parameters specifying activating buttons can also be provided for the source wave. Using a host processor or a local processor, the force signal is formed from the source wave and the sets of control parameters and impulse parameters, where the force signal includes an impulse signal followed by a continual steady-state signal after an expiration of the settle time. A feel sensation is generated to a user of the force feedback device as physical forces produced by actuators on the force feedback device in response to the force signal. The steady-state magnitude value is lower than a magnitude value of a non-impulse-shaped force signal required to create a corresponding feel sensation having a similar apparent sensation to the user.

Overflow downdrawn glass forming method and apparatus

One embodiment of the present invention is an improved sheet glass forming apparatus. In another embodiment, a precise thermal control system redistributes the flow of molten glass at the weirs to counteract the degradation of the sheet forming apparatus which inevitably occurs during manufacturing. In yet another embodiment, the invention introduces a counteracting force to the stresses on the trough in a manner such that the thermal creep which inevitably occurs has a minimum impact on the glass flow characteristics of the forming trough. Another embodiment creates a variable external cross-section which provides hydraulic stresses that are in opposition to the surface tension and body force stresses and thus, reduces the influence of surface tension and body forces. In an alternative embodiment, the glass is preferentially cooled across its width to create forming stresses during solidification, which ensures that the glass sheet drawn is inherently flat. In an additional embodiment, the internal pressure is adjusted in each of the major components of the forming apparatus such that the pressure difference across any leakage path to the forming zone is essentially zero. Therefore, air leakage in the apparatus is minimized even though the cracks and openings exist during initial operation and develop during manufacturing.

Method for manufacturing semiconductor device

An object is to provide a manufacturing method of a semiconductor device in which a defect in characteristics due to a crack occurring in a semiconductor device is reduced. Provision of a crack suppression layer formed of a metal film in the periphery of a semiconductor element makes it possible to suppress a crack occurring from the outer periphery of a substrate and reduce damage to the semiconductor element. In addition, even if the semiconductor device is subjected to physical forces from the outer periphery in separation and transposition steps, progression (growth) of a crack to the semiconductor device can be suppressed by the crack suppression layer.

Method and system for coordinating collisions between augmented reality and real reality

InactiveUS20130155106A1Smoother and intuitive connectionCathode-ray tube indicatorsImage generationVirtual worldComputer science
A method and system for coordinating placement of an augmented reality / virtual world object(s) into a scene relative to position and orientation. The object(s) can be connected to an anchor point having an absolute location relative to the marker via a connector (e.g., spring-like connector) in such a way that the behavior of the object responds to a physical force and a collision which exists in the augmented reality scene. The connection between the virtual object and location of the marker permits the object to exactly track the marker when there are no real world collisions between the markers. The virtual objects can be displaced so the objects do not pass through one another when the real world markers come into a close spatial proximity and the corresponding virtual objects begin to collide.

Fluidic force discrimination

This invention describes a method of using controlled fluidic forces to improve the performance of a biochemical binding assay where a target molecule is captured by specific molecular recognition onto a substrate surface with an affinity coating, and then labeled with a detectable micrometer-scale particle using a second specific molecular recognition reaction with the target. By using specific ranges of label sizes and laminar flow conditions, controlled fluidic forces can be applied to the label particles in order to selectively remove molecules bound to a surface according to their binding strength, and thereby increase the ratio of specifically bound labels to more weakly attached non-specifically bound labels. This method can be used with a wide variety of label types and associated detection methods, improving the sensitivity and selectivity of a broad range of binding assays.

Substrate treating apparatus and substrate treating method

A control unit controls a lifter to raise at least part of each of a group of substrates above the liquid level of a treating liquid in a treating bath. Thereafter, a valve is opened to drain the treating liquid from the treating bath at a high speed. As a result, a physical force to tilt and adhere an upper portion of the adjacent substrates accompanied by lowering of the liquid level of the treating liquid due to the high speed drainage acts upon a lower portion of the substrates near the lowered liquid level of the treating liquid, thereby reducing the physical force exerted on the substrates. This arrangement, even if a holding interval between the substrates is narrowed at a half of a normal pitch, eliminates a contact of the adjacent substrates and prevents damage of the substrates due to the contact without providing an additional member such as a substrate support guide in the treating bath.

Infusion Pump and Method Which Inhibits Unintended Tubing Withdrawal

A delivery tube is inhibited from unintended withdrawal from an infusion pump which has an internal occlusion clamp that clamps the delivery tube to prevent the free flow of fluid through the tube, by overlapping a blocking lip from a compression edge of the occlusion clamp with a restraint surface of an anvil against which the tubing is compressed and by overlapping a blocking projection from the restraint surface with the compression edge. Inhibition is also achieved by positioning an obstruction protrusion adjacent to the compression edge and the blocking lip to resist the application of exterior physical force to force the occlusion clamp from an occluding position to a non-occluding position.
