摘要:
A smart structure or an electronic package is formed by thermal spraying utilizing a plurality of masks positioned and removed over a work surface in accordance with a predetermined sequence. The masks correspond to cross sections normal to a centerline through the structure. Masks are placed above a work surface and sprayed with either at least one primary material to form at least one electronic component and a complementary material. In this manner, layers of material form a block of deposition material and complementary material. Then, the complementary material which serves as a support structure during forming may be removed.
摘要:
A portable computer system with an ergonomic input device is comprised of a housing having a top surface. A central processing unit is carried in the housing. A heads-up display is provided for displaying information to a user, with certain of the information being selectable by the user. The display is under the control of the central processing unit. A first rotary switch produces a first input signal for identifying the information to be selected. A second input switch produces a second input signal for selecting the identified information. Both the first and second input switches are carried on the top surface of the housing. An input interface receives the first and second input signals and encodes the information therein into an eight bit byte for input to the central processing unit. In one embodiment, the housing may be carried in a case which is worn by the user while the heads-up display is positioned proximate to the user's eye by a headband. The portable computer system can be used to browse hypertext documents, browse World Wide Web pages on the Internet and access interactive electronic technical manuals (IETMs).
