Inventor: DUNNE BRIAN B
IPC: F41G7/26
Filed: 1986-11-13
Granted: 1992-04-21
Abstract: SPIN-STABILIZED PROJECTILE WITH PULSE RECEIVER AND METHOD OF USE    Abstract of the Disclosure A spin-stabilized projectile the trajectory of which can be improved to increase accuracy with the projectile being controlled by a source of electromagnetic radiation providing pulses carrying encoded information.  The projectile includes a nose end and a midportion having a periphery disposed about which are a plurality of spaced masses with a high explosive charge associated with each mass for high explosive detonation acceleration of its corresponding mass to provide an impulse to the projectile.  A projectile has a boattail defining a cavity opened at the rear end of the boattail.  Received in the cavity is a pulsed electromagnetic radiation receiver and processor.  This radiation receiver and processor has a component for determining the approximate elapsed time from firing of the projectile, a component for determining the direction of the source of electromagnetic radiation with respect to the projectile, a component for determining approximate vertical, a component for determining rotational rate, and a component for counting the times between adjacent electromagnetic pulses in a series of such pulses.  The radiation receiver and processor also includes a microprocessor responsive to these components for controlling selective high explosive detonation acceleration of the masses to improve the trajectory of the projectile towards its target.  A method of controlling a number of such projectiles is also disclosed.

Title: Method and apparatus for transmitting a sychronous data signal on a transmission medium on which the transmission rate is greater than the data signal bit rate
Inventor: FORSBERG GUNNAR S
IPC: H04L7/00
Filed: 1988-03-08
Granted: 1991-12-03
Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for transmitting a synchronous data signal (D1) on a transmission medium on which the transmis-sion rate (Y bits/s) is greater than the data signal bit rate (X bits/s) are described.  The data signal is converted in a trans-mitter by over-sampling with a sampling frequency (Y Hz) which is equal to the transmission rate (Y bits/s) on the transmission medium, whereafter the data signal (D2) formed by the conversion is transmitted on the transmission medium.  A clock signal (C2) is formed in a receiver, this signal being phase-locked to the transmitted data signal (D2') and having a frequency (X Hz) equal to the bit rate (X bits/s) of the original, synchronous data sig-nal (D1), subsequent to which the transmitted data signal (D2') is re-sampled with the clock signal (C2) formed in the receiver. To avoid problems which can be caused by certain special bit com-binations of the synchronous data signal (D1) or of certain spe-cial frequency conditions between it and the transmitted signal (D2'), the data signal (D1) is converted in the transmitter such that an uneven distribution of the edges of the trnsmitted data signal (D2') in relation to their mean positions is avoided.

Title: Apparatus and method for providing a wireless link between two local area network systems
Inventor: VACON GARY V
IPC: H04L12/46
Filed: 1988-03-22
Granted: 1991-03-05
Abstract: Abstract In a data processing system network, apparatus and method are disclosed for coupling two local area networks by means of a wireless link.  Typically, two local area network (LAN) systems are coupled by a bridge device, the bridge device receiving signal groups from each LAN system and selectively forwarding the signal groups to the target LAN system.  In the presence of the overlapping (or simultaneous) transmission of signal groups applied to the target LAN system, these signal groups must be reapplied to the target LAN system until a non-overlapping transmission is obtained.  In the present invention, when the LAN system are coupled by a wireless (radiation) link, an interface unit is coupled between each wireless transmitter/detector unit and the associated LAN system.  Each interface unit includes a bridge device that provides the system response to the overlapping signal groups.

Title: Position transducer for use with a printer or plotter
Inventor: STODDER SAMUEL A
IPC: G01D9/40
Filed: 1988-04-14
Granted: 1992-05-19
Abstract: POSITION TRANSDUCER FOR USE WITH A PRINTER OR PLOTTER               ABSTRACT OF THE DISCLOSURE    A rigid link is provided between a plot medium (14) and a position transducer (50) so that accurate plot medium advance measurement can be attained.  The device (30) comprises a movable carriage (42) and an arm-like exten-sion (38) that juts out from the carriage to the plot medium.  A friction hold is made between the extension arm and the plot medium by applying a force to the extension arm normal to the plot medium by means of an electromagnet (33) which includes a coil (34), the extension arm serving as the armature.  The electromagnet is located beneath the platen (12) which supports the medium on a base (82) which also supports the carriage.   With the electromagnet activated, the extension arm is held against the plot medium.  As the plot medium is advanced by a plot medium drive system (20), the extension arm and carriage are pulled along.  Plot medium advance is stopped when the proper advance distance has been sensed by the position transducer.  The electromagnet is then deactivated and the extension arm and carriage are re-tracted by a return spring (48) to their original posi-tion.  The process can then be repeated for the next plot medium advance.  The length of a single move is short but sufficient for a scanning type plotter or printer.

Title: Multiply folded laser systems
Inventor: CANTONI ARMANDO
IPC: H01S3/081
Filed: 1988-05-20
Granted: 1993-01-05
Abstract: Abstract of the Disclosure A laser resonator, having multiply folded optical paths in an extended region by a set of front surface reflecting elements, can be used in a gas laser oscillator or amplifier, in either continuous wave mode or pulsed mode. This optical path is folded into larger domains within a polygon area of the laser cavity, thereby achieving increasingly longer laser paths without a corresponding increase in the number of folding elements. The resulting domains fully cover the plane with a grid of evenly spaced and intersecting optical paths.      In one embodiment, a waveguide gas laser system with a ceramic block having a multiply folded optical path of intersecting waveguide channels cut into the block. The reflecting mirrors of the laser resonator are integrally attached tot he ceramic block, enhancing the durability of the laser resonator and reducing its size. Since the laser medium is gaseous, the matching of refractive indices is not required.
