    • A flexible sleeve includes a first flexible sheet of a first hardness. The first flexible sheet has a first perimeter including a first lip edge and a first pocket edge. The flexible sleeve also includes a second flexible sheet of a second hardness, different than the first hardness. The second flexible sheet has a second perimeter including a second lip edge and a second pocket edge. The second pocket edge is joined to the first pocket edge, and the second lip edge is free from the first lip edge so that the first flexible sheet and the second flexible sheet collectively form a pocket having a mouth defined by the first lip edge and the second lip edge. The flexible sleeve further includes a connector joined to the mouth and configured to mate the mouth to a head of a device while the pocket substantially covers a tail of the device.

    • Provided herein are self-calibrating timing circuits and methods for use in a sync separator. A comparator compares a video signal to a video reference voltage to produce a sliced sync signal that has a frequency that is equal to a scan frequency of a horizontal sync embedded in the video signal. A first converter converts the sliced sync signal to a control signal having an amplitude or magnitude that is inversely proportional to the scan period of the horizontal sync embedded the video signal. A second converter converts the voltage control signal to a timer signal that has timed intervals that are that are inversely proportional to the amplitude or magnitude of the control signal, and thus proportional to the scan period of the horizontal sync embedded in the video signal. These timed intervals produced in accordance with embodiments of the present invention are easily and precisely scalable, allowing them to be used to discriminate various timing features embedded in video signals. This abstract is not intended to be a complete description of, or limit the scope of, the invention.
    • 本文提供了用于同步分离器的自校准定时电路和方法。 比较器将视频信号与视频参考电压进行比较,以产生具有等于嵌入在视频信号中的水平同步的扫描频率的频率的分片同步信号。 第一转换器将切片的同步信号转换成具有与嵌入视频信号的水平同步的扫描周期成反比的幅度或幅度的控制信号。 第二转换器将电压控制信号转换成具有与控制信号的幅度或幅度成反比的定时间隔的定时器信号,并且因此与嵌入在视频信号中的水平同步的扫描周期成比例。 根据本发明的实施例产生的这些定时间隔容易且精确地可扩展,允许它们用于区分嵌入在视频信号中的各种定时特征。 本摘要不是对本发明的完整描述或限制本发明的范围。
