摘要： A portable phone includes a handset and a data projection system configured to form a visual image of data, such as caller waiting ID data, on a viewing surface viewable by a user during a two way conversation. The handset also includes a speaker, a microphone, conventional phone circuitry and a keyboard. The data projection system is configured to receive signals from the phone circuitry, to generate a pattern representative of the data, to process the pattern into a mirror image of the visual image, and to project the mirror image from a bottom end surface of the handset. The projection system includes an electro optic system for generating the pattern, and an optics system for projecting the mirror image onto the viewing surface. A method for projecting data in a portable phone includes the steps of: providing the handset with the data projection system, conducting a two way conversation with the handset held against the head of the user, and forming the visual image on the viewing surface during the two way conversation with the handset held against the head. The method can also include the steps of manipulating the handset and a body part to locate and focus the visual image, sensing an orientation of the handset during the two way conversation, and orienting the visual image as a function of the sensing step.

摘要： A remote keyboard has keys which are illuminated for identification under a dim motherboard. For a first embodiment of the invention, the identifying symbol or symbols on each key cap of the keyboard is formed from luminescent material. Alternatively, the symbol or symbols on each key cap are formed from a translucent material in which tritium is embedded. Tritium, which has a half-life of about 12.5 years, emits low-energy beta particle radiation. The radiation, which is of sufficiently low energy that it may be blocked by a piece of paper, may be rendered innocuous by placing clear plastic radiation shields over each key cap. For a second embodiment of the invention, the key caps themselves are molded from luminescent material, while the symbols are formed from contrasting black or dark-colored non-luminescent material. A third embodiment of the invention utilizes fiber optics to convey light from at least one low-power source, such as a light-emitting diode, to each of the various key caps, each of which is molded from a translucent material. The symbols on the key caps are of a color which contrasts with that of the key caps. Black letters on light colored translucent key caps are the preferred combination. Another embodiment of the present invention for backlighting a keyboard is to use a transparent projector pane positioned beneath translucent or transparent key caps on which identifying symbols are printed. Light from a light source at the edge of the projector pane is transmitted throughout the pane. An aperture beneath each key top projects light up through the key caps, illuminating the symbols.
摘要翻译：远程键盘具有被照亮以在暗淡的主板下识别的按键。对于本发明的第一实施例，键盘的每个键帽上的识别符号或符号由发光材料形成。或者，每个键帽上的符号或符号由其中嵌入有氚的半透明材料形成。氚的半衰期约为12.5年，发射出低能β粒子辐射。通过在每个键帽上放置透明的塑料辐射屏蔽，其可能被一张纸阻塞的足够低的能量的辐射可能变得无害。对于本发明的第二实施例，键帽本身由发光材料模制，而符号由对比黑色或深色非发光材料形成。本发明的第三实施例利用光纤将来自至少一个低功率源（例如发光二极管）的光传送到各个密封帽中的每一个，其中每个由半透明材料模制。键帽上的符号是与键帽的符号形成对比的颜色。浅色半透明键帽上的黑色字母是首选组合。用于背光键盘的本发明的另一实施例是使用位于半透明或透明键帽下方的透明投影仪窗格，其上印有识别符号。来自投影仪窗格边缘的光源的光在整个窗格中传输。每个键顶下方的孔径通过键帽突出，照亮符号。

摘要： A radio frequency communication device and methods of testing and tuning an antenna attached thereto are disclosed. A radio frequency communication device comprises internal circuitry and an antenna having a plurality of antenna segments associated therewith. Each antenna segment is associated with the antenna in either series or parallel relation through at least one of a fuse and an antifuse. In testing and tuning, a comparison is made to indicate whether the antenna is too short or too long. If the antenna is too short, an antenna segment may be attached to the antenna by initiating an antifuse. If the antenna is too long, an antenna segment may be detached from the antenna by blowing a fuse. If it is indeterminate whether the antenna is too short or too long, an antenna segment may be either attached or detached, the test repeated, and the results of the repeated test compared with the prior test to determine whether the correct action was taken.

摘要： The disclosed method for forming a field emission display includes forming a cathode and an anode, forming a plurality of photoresist posts over the cathode, and coating the posts with a layer of coating material. The layer of coating material forms sidewalls around the posts. The photoresist posts may then be removed from within the sidewalls. The anode may then be fitted onto the sidewalls so that the sidewalls function as spacers in the field emission display.
