摘要： A portable data sensing and processing device for a SCUBA diver using a tank of compressed air wherein the device provides integrated information to the diver on a liquid crystal display screen to permit the diver to make a longer time variable depth underwater dive than would be permitted by the U.S. Navy dive tables for a no-decompression ascent.

摘要： In a system for displaying prices in a retail store, improved system architecture and stored programs are disclosed to permit improved accuracy in confirming the physical location of display devices called labels. A response from a label to the host, or central computer, has appended to it an additional message by an appender, one of a plurality of appenders located throughout the architecture. The appender's message permits localization of the labels. A power-on status flag in a response from the labels permits the central computer to determine, through global inquiries to all the labels, whether any of the labels has had an interruption of power. A dongle or RF-linked bar-code scanner permits store personnel to send messages to the central computer to request that labels in a particular subarea of the store display alternative information such as the amount of inventory for items in that subarea.

摘要： An improved electronic price display system has rails into which are installed price display labels. Ridges along the top and bottom of the rails are shaped to receive a label readily. A removal tool may be engaged to release the pawls of the label to extract the label. Ridges at the rear of the rails, together with a resilient insert, permit quick mounting to a shelf with a minimal number of fasteners. A hemicylindrical feature at the back of the rails permits generous area of contact with a mounting screw having a hemispherical head. Opposed groove features permit the concealment of the screw heads and provide a visual design element.Angled ridges on the rear face of the label engage with knurls on the rails providing contact wiping, enhancing electrical integrity of the label-to-rail connection, and also fix the label in place.A feature along an edge of the rail provides a cylindrical concavity. An optional clear plastic cover mounted with a cylindrical edge bead in the concavity provides a hinged connection therebetween. A protruding button on the face of the label is actuated by the pressing of the cover in the vicinity of the button.A subassembly of the label provides a robust carrier for springy contacts providing electrical connection long conductors on the rails.

摘要： An electronic price displaying label is disclosed for use in conjunction with a rail, the rail having two lips which define an access slot and a cavity, in which the label is prevented from slidably moving in a horizontal direction along the rail. The label has a protuberance connected to the rear of the label and first and second grooves arranged on the rear of the label such that the label can be secured in a display position along the rail. The aforementioned grooves disposed on the rear of the label contain a resilient substance such as a rubber band. The protuberance of the label may be removed from and inserted into the cavity of the rail when the label is in a position perpendicular to the rail, with the protuberance securing the label to the rail when the label is in a position parallel to the rail. Upon attaching the label on the rail, the compression of the resilient substance by the lips of the rail prevents the label from slidably moving in a horizontal direction along the rail.
摘要翻译： 公开了一种与轨道一起使用的电子价格显示标签，该轨道具有限定出入口狭槽和空腔的两个唇缘，其中防止标签沿着轨道在水平方向上滑动移动。 标签具有连接到标签后部的突起，并且布置在标签后部的第一和第二凹槽使得标签可以沿着轨道固定在显示位置。 设置在标签后部的上述凹槽包含橡胶带等弹性物质。 当标签处于垂直于轨道的位置时，标签的突起可以从导轨的空腔中移除并插入轨道的空腔中，当标签处于与轨道平行的位置时，突起将标签固定在轨道上。 一旦将标签安装在轨道上，则由轨道的唇缘压缩弹性物质就能防止标签沿着轨道在水平方向上滑动。

摘要： A liquid crystal shutter system for selecting fields of a field-sequential image, by transmitting the field-sequential image, with a synchronization signal, to one or more remote liquid crystal cell shutter assemblies. Each shutter assembly transmits selected fields of the field-sequential image in response to a drive signal, and includes a drive circuit for receiving the synchronization signal and generating each drive signal in response to the synchronization signal so that each drive signal has transitions synchronized with image fields. The drive circuit is capable of rapidly processing short duration synchronization signals with very low power consumption. In one embodiment, two liquid crystal cell assemblies are mounted in an eyeglass frame and used as a wireless selection device for a field-sequential stereoscopic image. Preferably, the invention includes a synchronization signal receiver having a narrow angular reception range so that the receiver is sensitive to only one synchronization signal at a time, so that the invention may be employed to view several monitors without interference between different synchronization signals from the different monitors. Preferably, the inventive shutter assemblies are capable of operating in a nonoccluding state, and each inventive shutter assembly may conveniently be switched between a state suitable for stereoscopic viewing and a non-occluding state suitable for viewing a non-stereoscopic image.
