Search apparatus is described for locating an item which satisfies a predetermined criterion e.g. an instruction ready for execution or a free block of data. The apparatus uses a tree structure where each terminal node represents one of the items and is set if that item satisfies the criterion. A non-terminal node is set if any of its subordinate nodes is set. In order to locate an item, a path is traced through the tree, starting at the root node and passing through a series of set nodes until ...

A hand held search light includes a miniaturized electronic control circuit for igniting and operating an arc lamp in the light. Lamp mounting means is disclosed for shock mounting the arc lamp, including means to center and focus the light beam emitted by the search light. The search light is modularized for ease of field maintenance by unskilled personnel.

A Search memory organization using as the designator words, which words are the words that are stored in the Search memory and that are compared to the one search word held in the search register, words that are generated from blocks of data words is disclosed. Each of the (block) designator words includes two portions: a first common portion that includes the binary data that are common to all the data words of the block; and, a second word portion that includes the binary data that are not com...

A trained processor is described which operates beyond an untrained point. Information is stored in a memory array in a tree-allocated file. Information is stored in the memory as key functions with associated trained responses. After the processor has been trained, it is able during an execution cycle, to find appropriate responses for query key functions. These query key functions are compared with the reference key functions stored in the memory array to find an appropriate trained response. ...

2. A search system for detecting moving targets, in chaff, and including a ransmitter for reflecting bursts of randomly phase coded, electromagnetic energy from a target, and a receiver, said receiver comprising A delay line having a plurality of output taps thereon, Means for applying said reflected bursts to said delay line, A plurality of phase shifters which are preset in accordance with the phase coding of said transmitter, Each phase shifting means being connected to a different output tap...

A pulsed doppler search radar is disclosed in which range, bearing, and radial velocity are made available for display. The radar incorporates a capacitor matrix correlator and an improved method of range determination utilizing passive decoding circuitry and sequential unblanking of the capacitor correlator matrix drivers where required. Moreover, a passive implementation of the doppler direction algorithm is provided in which a summing circuit is implemented on the same printed circuit board u...

A device for searching and retrieving objects on a tube sheet of a steam generator which includes a sled having a probe and a gripper thereon and connected to a flexible tube having control means therein for operating the probe and the gripper whereby the sled and flexible tube may be inserted through a handhole of the generator to an operating position on the tube sheet. Both the probe and the gripper may be angularly rotated to manipulate them between the tubes of the steam generator.

A computer program provides for the display of selected portions of two or more records on a display screen where the portions selected are from different records, and may be from different files. Provision is made for scrolling of the full text of the displayed records, which may be grouped by common subject matter. Alternatively one of the two or more records may be displayed on the full screen with the capability for selectively switching between the single record and two or more records or a...
