摘要： A hand-held TV/computer remote infrared control device has an elongated rectangular housing with a front longitudinal portion and a considerably shorter rear end portion which is downwardly and rearwardly inclined relative to the front portion and has a generally bulbous underside section which may be grasped from below by a control hand of a user, with the elongated front portion extending forwardly beyond the control hand. The device is stabilized against forward tipping in the user's hand by positioning somewhat more than half of the operating weight of the device in its rear end portion. Various control buttons are disposed on the top side of the front portion, and the downward tilt of the grasped rear end portion causes the front end portion to tip upwardly to make the control buttons easier to see by the user. A computer pointing structure, in the form of a track ball and two associated selection buttons, is disposed on the top side of the rear end portion, and an auxiliary computer selection button is disposed on the bottom side of the housing at the juncture of its front portion and rear end portion. The track ball and the two top side selection buttons are positioned to be used by the user's control hand thumb, and the auxiliary selection button is positioned to be used trigger-like by the control hand index finger.

摘要： A method of using a work station having separate front and back tops having separate powered drive arrangements for permitting independent height adjustment. A controller, which is programmed by an operator, permits storage of a number of predetermined height locations each defining distinct heights for both tops. The operator effects programmed movement of the tops to predetermined height locations for predetermined times and in a predetermined sequence, with the rear top moving initially and the front top moving thereafter.
摘要翻译：一种使用具有分离的前后顶部的工作站的方法，其具有分开的动力驱动装置，用于允许独立的高度调节。由操作者编程的控制器允许存储多个预定的高度位置，每个高度位置为两个顶部定义不同的高度。操作者将顶部的程序移动预定的时间和预定的顺序进行到预定的高度位置，其中后部顶部最初移动，并且其前后移动。
