    • Organic compounds, e.g. fluorinated organic compounds such as fluorinated carboxylic acids or fluorinated carboxylic acid chlorides, may contain small amounts of carboxylic acid fluorides, hydrogen fluoride or hydrolyzable fluoride, which during the preparation of derivatives of the fluorinated organic compounds, for example by esterification, may yield corrosive fluorides or hydrogen fluoride. The invention is a method for the synthesis and/or purification of preferably fluorinated organic compounds such as carboxylic acids, carboxylic acid chlorides and derivatives such as esters thereof, starting from corresponding carboxylic acid chlorides containing acid fluorides or hydrolyzable fluoride, and alcohols under the catalytic action of “onium” salts of carboxylic acids, to obtain products which have a low fluoride content. Alternatively, an inorganic oxide adsorbent is utilized. The method is especially suitable for the synthesis of esters of trifluoroacetic acid, chlorodifluoroacetic acid, trifluoroacetoacetic acid and/or difluoroacetoacetic acid.
    • 有机化合物,例如 含氟有机化合物如氟化羧酸或氟化羧酸氯化物可含有少量羧酸氟化物,氟化氢或水解性氟化物,其在氟化有机化合物衍生物的制备过程中,例如通过酯化反应,可产生腐蚀性氟化物 或氟化氢。 本发明是一种合成和/或纯化优选氟化有机化合物如羧酸,羧酸氯化物及其衍生物如酯的方法,起始于含有酸性氟化物或可水解氟化物的相应的羧酸氯化物和催化剂下的醇 羧酸的“鎓”盐的作用,以获得具有低氟含量的产物。 或者,使用无机氧化物吸附剂。 该方法特别适用于三氟乙酸,氯二氟乙酸,三氟乙酰乙酸和/或二氟乙酰乙酸的酯的合成。

    • Disclosed are systems, methods, and devices for interfacing with a wearable heads-up display via a touch-operable input device. The wearable heads-up display may include a display element for receiving and displaying display information received from a processor, and may also include a wearable frame structure supporting the display element and having a side-arm extending away from the display element. In some embodiments, the display information may appear at least partially curved to a user. In some embodiments, only a portion of the display information is shown on the at least one display element. The side-arm may be configured to secure the heads-up display to a user's body in a manner such that the display element is disposed within a field of view of the user. The touch-operable input device secured to the wearable frame structure is configured to sense at least one of a position and movement of a touch or finger along a planar direction relative to a surface of the input device, and to provide corresponding input information to the processor. A navigation tool may also be displayed on the at least one display element for indicating the location of the touch on the touch-operable input device.
    • 公开了用于通过可触摸操作的输入设备与可穿戴式平视显示器进行接口的系统,方法和设备。 可穿戴式平视显示器可以包括用于接收和显示从处理器接收的显示信息的显示元件,并且还可以包括支撑显示元件并具有远离显示元件延伸的侧臂的可穿戴框架结构。 在一些实施例中,显示信息可以至少部分地向用户弯曲。 在一些实施例中,在至少一个显示元件上仅显示显示信息的一部分。 侧臂可以被配置成以使得显示元件设置在用户的视野内的方式将平视显示器固定到用户的身体。 固定到可穿戴框架结构的触摸可操作输入装置被配置为感测触摸或手指沿着相对于输入装置的表面的平面方向的位置和移动中的至少一个,并且向相对于输入装置的表面提供相应的输入信息 处理器。 也可以在至少一个显示元件上显示导航工具,以指示触摸可操作的输入设备上的触摸的位置。
