摘要： Projector and camera arrangements are provided for use in electronic whiteboard systems. Specifically, the present invention provides projector and camera arrangements wherein the projector and camera share the same imaging optics. By sharing the same projection and camera optics, the distortions that affect the projection system are the same as those of the camera system. Thus, the calibration step required in conventional whiteboard systems where the projector and camera are separate, i.e., each having their own distinct optics and settings, is no longer needed. Further, the arrangements provided in accordance with the invention are self-aligning, even when lens distortions are large and even in the presence of strong perspective effects. The shared optics projector and camera arrangements of the invention also provide for dynamic zooming. In addition, various active and passive optical marker or lightpen designs are provided for use in electronic whiteboard systems.

摘要： Approaches for a single part that comprises an upstream spoiler and a crash stop for use within a hard-disk drive (HDD). The integrated upstream spoiler and crash stop has one or more wings which diverts and reduces the flow of air, resulting from the rotation of the magnetic-recording disks within the HDD, from a magnetic-recording head of the HDD. The integrated upstream spoiler and crash stop has a structure that also prevents the actuator from moving beyond a particular location. After the integrated upstream spoiler and crash stop has been affixed within the HDD, the one or more wings may be rotated between the one or more magnetic-recording disks into a desired position.

摘要： Approaches for determining the likelihood that a hard-disk drive (HDD) will experience an imminent error in operation, and preventing the same, using an atmospheric pressure sensor are provided. The HDD comprises an atmospheric pressure sensor capable of determining the altitude at which the HDD is currently located. The HDD also comprises a risk assessment component capable of (a) determining an expression of how likely it is that the HDD will experience an imminent error in operation based, at least in part, upon the current altitude of the HDD, and (b) communicating the expression to a user of the HDD. The HDD may optionally comprise one or more of a particle counter, differential pressure sensor, and a chemical vapor sensor for use by the risk assessment component. If the HDD is above a particular altitude, the Thermal Fly-Height control settings of the heads may be adjusted to reduce risk of error.
