International Classification:

C04B 700

US Classification:

106 85

Abstract:

A dry, mineral binder composition is disclosed having from 6 to 25 parts by weight metakaolin, 3 to 30 parts by weight dry potassium hydroxide, 0 to 18 parts by weight slag, 0 to 60 parts by weight of a material selected from the class consisting of fly ash, calcined shale, and calcined clay, and from 1 to 150 parts, by weight, of a finely divided silica, preferably an amorphous silica. The binder is particularly useful in combination with Portland cement for forming concrete compositions.

Appl. No.:

8/197903

Inventors:

Mark R. FitzGerald - Phoenix AZ
Craig T. Griffin - Chandler AZ

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

F41G 101

US Classification:

434 16

Abstract:

A method and apparatus controls the display of information for troops and vehicles in a simulated battlefield. Rounds of munition are fired into the simulated battlefield and the effects of such munitions are displayed on the troops and vehicles display devices. These display devices include character displays for troops and display screen for vehicles. The text character display may include such information as damage assessment, weapon type, miss distance and miss direction. A screen display may be used for a vehicle display. The screen display depicts similar information as for the text character display, but in a graphical representation via icons representing various battlefield effects.

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

F41A 3300

US Classification:

434 11

Abstract:

Non-pyrotechnic cues are used with an area weapons effects system. These cues include sound devices, flashing lights and smoke deposition devices. A processor detects the required type of display from an input message and displays an appropriate sound to correspond to the type of weapon used. In addition, visual displays are coordinated with the audio display to provide simulated explosions with appropriate sounds ("bangs") and lights ("flashing lights") and smoke.

Appl. No.:

8/251153

Inventors:

Mark R. FitzGerald - Phoenix AZ
Craig T. Griffin - Chandler AZ
Glen E. Sater - Phoenix AZ

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

F41G 326

US Classification:

434 27

Abstract:

A method for providing detection of timing anomalies and eliminating falsely detected positions in a hyperbolic positioning system for a simulated battlefield system. The method selects a large number of transmitters for calculation of position of an object or person on the battle field. In addition, transmitters are selected which have a high dilution of precision factor.

Appl. No.:

8/653537

Inventors:

Mark Richard FitzGerald - Phoenix AZ

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

B64D 100

US Classification:

434 16

Abstract:

A method simulates the time effect of a battlefield engagement. The method determines whether a player is in an area of effects (27). A probability of kill is generated for the player (30). The player is assessed results of kill or near-miss (31-33). The method is repeated for a selected time duration (39).

Mark R. FitzGerald - Phoenix AZ

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G01S 108
G01S 502
F41G 326

US Classification:

342386

Abstract:

A time transfer position location method and arrangement. A mission control station initiates a number of relays placed throughout a simulated battlefield. Each of the relays then obtains position and time information from a Global Positioning System (GPS) satellite. Each relay repeatedly transmits position information (timing pulse) in a particular time slot over the playing field. In addition, fire mission information which includes type of munition deployed and its range and affects is also transmitted.

International Classification:

C04B 700

US Classification:

106 85

Abstract:

A binder composition for Portland cement is disclosed, said composition including 100 parts by weight metakaolin and, based upon said metakaolin, from 20 to 70 parts by weight slag; from 85 to 130 parts by weight of at least 1 material selected from the class consisting of fly ash, calcined shale, and calcined clay; from 70 to 215 parts by weight finely divided silica, preferably amorphous silica; and from 55 to 145 parts by weight of a mixture of potassium silicate and potassium hydroxide, wherein at least 55 parts by weight is potassium silicate. The binder composition can be mixed with Portland cement or with a combination of Portland cement and fly ash to provide a composition curable to a material having a high early strength and a high ultimate strength.
