Abstract: The present invention relates to a method and device for providing a graphical user interface between an individual soldier and a computer-based warfare system worn by him. The graphical user interface is made up of icon-based visual control and information screens that the soldier views on a display and manipulates with a computer mouse-like device. The interface allows the individual soldier to: view information gathered by a variety of sources, inccluding sensor components, radios, and satellites; process information using a variety of input devices and software utilities; and, act on that information using weapons, communications devices, and the like. The graphical user interface organizes information into three distinct "combat task" groups and provides the soldier with easily understood pictorial icons to select. By tailoring the information to a particular situation, the graphical user interface allows the soldier to view critical data without being overwhelmed by too much information.

Title: Fastener-driving tool assembly with improved fastener-loading features
Inventor: DEWEY GEORGE G
IPC: B27F7/09
Filed: 1992-09-04
Abstract: Disclosed  is  a  portable  stand-up  tool  assembly  (10) comprising a powder actuated nail-driving tool arranged to drive a nail (20)  of a type comprising a shank (22)  defining an axis and having a tip (24) at one end, and a head (26)  integral with the other end of the shank.   A resiliently biased nosepiece assembly (36) has an aperture (122)  arranged to permit the nail (20) to be axially driven through it and a nail transport mechanism is responsive to depression of the resiliently biased nose piece assembly, when pressing the tool assembly downwardly against a work piece whilst standing on the workpiece,  and subsequent release of the resiliently biased nose piece assembly, for transporting a nail in a direction transverse to the nail axis into a delivery position with the nail aligned axially with the aperture.  A driving element (52) engages the nail head (26) so as to drive the nail (20)  axially through the aperture (122) and the nail (20)  is retained in the delivery position so as to prevent the nail (20)  from dropping accidentally but so as to permit the nail (20) to be axially driven by the driving element (52).  A handle (58) and trigger (60) are located remote from the nosepiece (36) to enable an operator to actuate the driving means to drive nails into a workpiece from a position standing on the workpiece and, there is a nail guide (104)  for receiving nails loaded at a position located substantially adjacent the handle (58)  and trigger (60).

Inventor: CLARK THOMAS R
IPC: E05B47/00
Filed: 1997-12-12
Abstract: A self powered lock is powered by a manually driven generator. The data input to the lock is entered by rotating the dial and stopping and waiting a predetermined amount of time when a desired number is displayed on the lock display. The drive of the power generator, a stepper motor, is through a unidirectional clutch. such that the generator is only driven when the dial is rotated in a selected direction and remains stationary when the dial is rotated in the opposite direction. The data input, including entry of the combination, to the lock is provided by a stepper motor which generates a train of electrical pulses. The electrical pulses are used by the electronic controls of the lock to control the electronic controls including entering the combination. The data input pulses are generated by a stepper motor driven to act as a generator. The data input generator is similarly driven through a unidirectional clutch and is driven only when the dial is being rotated in a direction opposite the direction in which the power generator is driven. Accordingly, only the power generator or the data input generator is driven at any one time, depending upon the direction of rotation of the dial. A third unidirectional clutch is used to grasp the shaft of the data input stepper motor, preventing the reverse rotation of the rotor when the dial of the lock is rotated to generate operating power.

Title: Acides de decapage inhibes contenant des ions chlorure et zinc
Inventor: BLACK GERALD A
IPC: C23G1/06
Filed: 1996-07-12
Abstract: Des inhibiteurs contenant un noyau triazine, lesquels ont été largement vantés dans les techniques actuelles comme étant d'excellents inhibiteurs de compositions décapantes à base d'acide chlorhydrique, ne se sont pas révélés efficaces lors d'une utilisation prolongée quand les composition décapantes peuvent dissoudre des quantités importantes d'ions zinc, car l'inhibiteur précipite comme un solide en présence à la fois d'ions zinc et d'ions chlorure. D'autres inhibiteurs de décapants contenant de l'azote ne présentent pas cet inconvénient et fonctionnent de manière efficace, même en présence de zinc. Des combinaisons d'inhibiteurs de polyalkylèneamine d'alkyle aryle et de tétramine d'hexaméthylène sont particulièrement efficaces.

Title: Sandwich box
Inventor: HANNA DAVID M
IPC: B65D5/46
Filed: 1998-08-26
Abstract: A wrapper-type box for transporting a sandwich. The box is formed from a one-piece flat blank of stiff but foldable cardboard. The blank has a main part with a plurality of parallel fold lines which divide the main part into four adjacent side walls. The main part is folded about the fold lines to assume an elongate tubular body of rectangular configuration. An edge flap and a top wall overlap and have cooperating locking tabs and slots to secure the main part in an assembled condition.      The edge flap also has a looplike handle formed therein.      The one-piece blank also includes a pair of flaps associated with and projecting outwardly from each end.      To effect closure of the end of the tubular body, the pair of flaps are folded inwardly into the box interior through a sufficient angle so that a tab on one flap passes over the other flap and projects into a slot provided on the other flap. The manual folding force is released, and the memory of the flaps causes the flaps to swing outwardly and effectively engage the tab within the slot and lock the flaps together.

Abstract: A method of optical imaging through a scattering medium is provided in which a fit is made to an inhomogeneous diffusion model. The method facilitates good differentiation between scattering and absorption. The variation of the diffusion curve associated with the presence of an inclusion is considered rather than the diffusion curve itself. An empirical model is provided which describes the variation of the diffusion curve. A linear curve fitting process is performed to provide two parameters, one parameter associated with the scattering property of the inclusion and the other parameter associated with the absorption property of the inclusion.
