摘要： Disclosed is an eye-start system that includes a light source adapted to be housed within a viewfinder of a device, and a light sensor also adapted to be housed within the device viewfinder, the light sensor being configured to sense light from the light source that reflects off of a user looking into the viewfinder. With this system, light reflected off of the user is sensed by the light sensor and, upon such an occurrence, a device action is activated.

摘要： A focus lens and a zoom lens group having a first zoom lens and a second zoom lens are controlled separately from one another in an internal-focus camera. The positions of the focus lens and the second zoom lens in the zoom lens group are tracked, and are controlled to approach no closer to one another than a minimum safe distance to avert collisions between the focus lens and the second zoom lens.

摘要： An illumination system for illuminating a scan region on an object and for providing a white level reference for a detector may comprise a light source for producing light rays and an elongate lens having a first end and a second end positioned between the light source and the scan region. The lens collects some of the light rays from the light source and directs them onto the scan region. A first spot lens is positioned adjacent the first end of the elongate lens and a second spot lens is positioned adjacent the second end of the elongate lens. The first and second spot lenses direct some of the light rays from the light source toward first and second ends of the scan line. A white level reference mark is positioned adjacent the lens and the light source so that some of the light rays from the light source are reflected by the white level reference mark to the detector.

摘要： A miniature rotary actuator optical head assembly incorporating data and servo detecting elements mounted inside a source/detector module, which is located on the rotary actuator arm adjacent to the pivot point of the rotary actuator arm. The miniature rotary actuator optical head also includes a miniature focus motor which supports a fold mirror and an objective lens and repositions the fold mirror and objective lens simultaneously whenever a focus error is received. The focus motor can be actuated by a magnetic bias field that originates external to the rotary actuator arm, particularly the magnetic bias field generated for magneto-optical recordation. The optical assembly may also include two stage tracking by mounting the light source on a pair of lateral movement flexures and supplying a fine tracking error signal to actuate the movement of the light source.

摘要： A two-stage beam positioning apparatus for use in an optical data storage device is provided. A fixed assembly includes a light beam source and detector, light beam focusing and track following apparatus. The fixed assembly is optically coupled to a movable assembly which provides coarse positioning of a focused light spot on a data storage medium such as an optical recording disc. The coarse positioning assembly is mechanically independent from the light beam source and detector assembly and, therefore, may be made very stiff and light resulting in a high bandwidth and reduced data access time. Since the light beam source and detector assembly and the focusing and track following control apparatus are mechanically isolated from the movable coarse positioning assembly, the size and mass of these components are not critical and do not affect data access time.
摘要翻译：提供了一种用于光学数据存储装置的两级光束定位装置。固定组件包括光束源和检测器，光束聚焦和跟踪跟踪装置。固定组件光学耦合到可移动组件，其提供聚焦光斑的粗略定位在诸如光学记录盘的数据存储介质上。粗定位组件在机械上独立于光束源和检测器组件，并且因此可以变得非常刚硬和光，导致高带宽和减少的数据访问时间。由于光束源和检测器组件以及聚焦跟踪跟随控制装置与可移动粗定位组件机械隔离，因此这些部件的尺寸和质量不是关键的，并且不影响数据访问时间。
