摘要： An ophthalmic illumination filter selection mechanism for use with an ophthalmic illumination system. Three filters are mounted in holders on a first shaft and rotatable into an optical light path determined by the ophthalmic illumination system. Each of three cams mounted on a second shaft is configured to move a holder on the first shaft to position the corresponding filter in the optical light path in a predefined sequence relative to the other filters as the second shaft is rotated in a forward direction. Each cam has a backlash that allows the second shaft to be rotated in a reverse direction for a predetermined radial distance to allow a last remaining filter to be removed from the optical light path. Each cam has a cam profile that ensures one filter remains in the optical light path until the next filter is driven into the optical light path when the second shaft is rotated in the forward direction. This mechanism occupies less space than conventional filter selection mechanisms.
摘要翻译： 一种用于眼科照明系统的眼科照明滤光器选择机构。 三个过滤器安装在第一轴上的支架中，并可旋转到由眼科照明系统确定的光学光路中。 安装在第二轴上的三个凸轮中的每一个构造成使第一轴上的保持器移动，以使第二轴沿向前方向旋转时以相对于其他过滤器的预定顺序将相应的过滤器定位在光学光路中。 每个凸轮具有间隙，允许第二轴沿相反方向旋转预定的径向距离，以允许最后一个剩余的过滤器从光学光路中移除。 每个凸轮具有凸轮轮廓，其确保一个过滤器保持在光学光路中，直到当第二轴沿向前方向旋转时，下一个过滤器被驱动到光学光路中。 这种机制占用的空间比传统的过滤器选择机制少。

摘要： An ophthalmic illumination system includes a collimated light beam focused onto an optical fiber for transmission of the light beam to an ophthalmic light probe. A light attenuator includes a pair of arrays positioned serially in a path for the collimated beam. The arrays are movable in parallel in the path about a rotational axis orthogonal to the path and between the arrays. Each array includes a plurality of regularly spaced-apart parallel plates, the parallel plates of one array being non-parallel to the plates of the other array.

摘要： One embodiment of the invention provides a method of televising a card game. Each playing card in the card game has a value. The method includes providing the back surface of each playing card with a marking that is substantially invisible to the naked eye. The marking indicates the value of the playing card. An infrared detector is used to access the marking to identify the value of a playing card involved in the card game. Visual information indicative of the identified value of the playing card is generated and included in a broadcast of the card game.
