    摘要: In an electronic device, plural circuit boards are plugged into respective connectors, or sockets, in a common backplane circuit board. The backplane maintains the flat circuit boards in fixed relation to one another. Each circuit board is provided with a respective optical transmitter and/or receiver to allow for the transmission of (typically digital) information via a high speed carrier in a light beam through unobstructed free space between the circuit boards. The circuit boards may also be provided with optical splitters and/or combiners as well as apertures to permit light signals to pass through the board's substrate to allow for communication between plural circuit boards. The circuit boards may further include small lenses and/or opaque elements to provide an optical path having selected physical characteristics. The light signals are transmitted through free space between the circuit boards in the connection of a circuit board in the electronic device is determined by the alignment of its optical transmitter and/or receiver to make the connection. With each circuit board typically “locked” into place in the backplane by means of latches, each circuit board is sized and configured so that when in position, the receivers and transmitters of the circuit boards are aligned so as to define a common signal path. Each circuit board is designed to determine in which slot in the backplane it has been inserted to permit the circuit boards to be used in a daisy-chain approach, allowing any circuit board to communicate with any other circuit board.

    摘要: An improved TCP/IP protocol for use in a client/server network is disclosed. The improved protocol allows a server to switch execution of an application from one processor or task to another processor or task without interruption of the IP connection or serious delay in execution of the application by a server or client. As implemented, each server usually includes a unique hardware address, an improved IP layer with a shared IP address, a "Speak No Evil-Communication Protocol" layer with a unique SNE-CP address, a soft switch protocol ("SSP") layer with at least one unique SSP address assigned to a process or task, usually a TCP layer, at least one SSP monitoring process and a processor executing at least one software application. In this invention, each server typically receives each message packet from each client; however, only one server is allowed to respond to the client's message. Thus, in the event that one processor or task faults, the application can be switched to another processor or task without interruption of the IP connection or serious delay in execution.

    摘要: A system for providing a competitive access provider controls specific lines in a remote terminal connected to a monopoly service provider connected directly from the remote terminal to a competitive access switch. In order to control the line or lines in the remote terminal, the competitive access provider switch sends signals via a signaling network to the monopoly service provider. In this manner, a competitive access provider may control a plurality of lines in a remote terminal without having to change a physical plant other than directing one or more DS 1 s or other trunks from the remote terminal to a host digital terminal on the competitive access provider network.

    摘要: A self-contained, battery powered, cableless starting device provides high DC power levels for short durations. Preferred devices have a battery, a connector terminal assembly, and a monitor/control circuit that indicates the voltage available, and limits the device output to safe voltage levels so the battery is not damaged. The connector terminal assembly preferably has 2 or more contacts, sized and dimensioned to electrically contact (mate) with selected electric starter auxiliary power input terminals. In another aspect of preferred embodiments, the coupling mechanism physically prevents the contact surface(s) from being positioned more than 5 feet from the battery. Commercial devices may advantageously include multiple batteries in a small carrying case, and have the appropriate capacity, voltage and connectors for starting a specific type of engine. For example, an especially preferred device has connectors suitable for starting a 12V or 24V powered aircraft. Such devices may advantageously have an overall stick shape, such as 2.times.3.times.14 inches, and may weigh only about 3 pounds.

    摘要: In the disclosed portable computer, a keyboard with keys for entering at least a full alphabet and ten digits is coupled to a computer system that includes a central processing unit which is in turn coupled to a display arrangement with a liquid crystal display. The entire computer is mounted in a case composed of a base and a cover hinged to the base. The base houses the computer system and the keyboard, and exposes the keyboard for operation by a user when the cover is open, while the cover houses the display arrangement and exposes the liquid crystal display on its inner surface. The cover is hinged at the edge of the base and, when closed, covers substantially the entire upper surface of the base.
