Abstract: The disclosed methods and apparatus improve the fabrication of solid fibers and microstructures. In many embodiments, the fabrication is from gaseous, solid, semi-solid, liquid, critical, and supercritical mixtures using one or more low molar mass precursor(s), in combination with one or more high molar mass precursor(s). The methods and systems generally employ the thermal diffusion/Soret effect to concentrate the low molar mass precursor at a reaction zone, where the presence of the high molar mass precursor contributes to this concentration, and may also contribute to the reaction and insulate the reaction zone, thereby achieving higher fiber growth rates and/or reduced energy/heat expenditures together with reduced homogeneous nucleation. In some embodiments, the invention also relates to the permanent or semi-permanent recording and/or reading of information on or within fabricated fibers and microstructures.

Abstract: The present disclosure generally relates to an improved penetrator design and associated arming generator relocator adaptor. In some embodiments, the arming generator relocator adaptor is positioned external to the penetrator, thereby removing the need to mount the FZU inside the warhead or include traditional internal plumbing. The arming generator relocator adaptor allows the FZU to be rotated to an optimal position to arm the penetrator. While the improved penetrator design and arming generator relocator adaptor can be used independently of each other, in the preferred embodiment, they are utilized together.

Abstract: A device for target scoring includes an elongated retro-reflective member, a first light source, a second light source, a first light sensor, a second light sensor and a processor. The first light source is disposed at a first location and is spaced apart from the retro-reflective member. The first light source is also positioned so as to be able to direct a first beam of light toward the retro-reflective member. The second light source is disposed at a second location spaced apart from both the retro-reflective member and from the first light source. The second light source is also positioned so as to be able to direct a second beam of light toward the retro-reflective member so that the second beam of light intersects the first beam of light over an area so as to define a target area. The first light sensor is disposed adjacent the first light source and is positioned so as to be able to receive light from the first light source that has been reflected from the retro-reflective member.

Abstract: A method and apparatus for communicating with chaotic and other waveforms employs a filter for estimating a parameter that describes a property of a signal. The filter is constructed by defining a system that models the source of the signal. The system is partitioned into a first subsystem that contains the parameter and a second subsystem that does not contain the parameter, the second subsystem including a term that makes the second subsystem stable and synchronizable with the signal. The signal is introduced as input to the second subsystem and an element of the second subsystem is substituted into a corresponding element of the first subsystem, thereby generating a signal-activated subsystem. An integration factor is introduced to the signal-activated subsystem to cause the parameter to behave as a constant when the signal-activated subsystem with the integration factor is integrated with respect to time.

Abstract: A scanner and a method for scanning a beam along a path employs a housing tint defines a first cylindrical cavity. A ring gear is disposed within the cylindrical cavity and affixed to the housing. A beam is generated from a fixed location relative to the housing. A drive disk is disposed within the first cylindrical cavity. The drive disk defines a second cylindrical cavity and has a first axis of rotation. The drive disk defines a first channel in communication with the beam. The first channel has a first proximal end pivotally rotatable about an axis adjacent the fixed location. A scan disk is disposed within the second cylindrical cavity and has a second axis of rotation offset from the first axis of rotation. The scan disk defines a second channel. The second channel has a second proximal end in communication with the first distal opening. The second proximal end pivotally rotates about an axis adjacent the first distal end.

Abstract: A hand-held controller wand including three angular rate measurement sensors is coupled to a computational device for translating roll, pitch, and yaw data into translation and rotation signals or commands that effect the movement of an external device's control point, which may be an end effector of a robot. A transformation matrix is continually updated from the angular rate information obtained from the hand-held controller. This matrix is used to update a direction vector. A value may be stored in the computation device corresponding to a predetermined speed of movement. A button or other convenient control allows the operator to control translational movement of the end effector or other controlled device in a direction defined by the orientation of the hand held controller at the predetermined speed, thus providing an intuitive control input for real-time direction and programming of movement.

Abstract: An acousto-optic apparatus is described that varies the time delay of electrical signals over a continuum of delays. In the preferred embodiment, a light source, which can be either coherent or incoherent, emits an optical beam that is focused into an acousto-optic cell. An input electrical signal is used to drive the acousto-optic cell which, in turn, modulates the focused optical beam. Portions of the input optical beam are modulated and diffracted at angles proportional to the frequencies and phases contained in the input electrical signal. By appropriately choosing the cone of angles at which the light is focused into the acousto-optic cell, the diffracted optical beam can be made to overlap with portions of the undiffracted, unmodulated optical beam. All of the light exiting the acousto-optic cell is then collected onto a device for detection. Optical photomixing of the diffracted beam and the undiffracted beam is performed in order to derive the input electrical signal with a time delay.

Abstract: An acousto-optic correlator for wideband signals. The invention is defined by and relates to device in which a laser beam is split into two paths of a Mach-Zehnder interferometer arrangement. A first Bragg cell of which, modulated with a signal Re{S.sub.1 (t)exp(jw.sub.o t)}, receives the first beam that is reflected off a first flat mirror. A second Bragg cell of which, modulated with a signal Re{S.sub.2 (t)exp(jw.sub.o t)}, receives a beam that is reflected off a second flat mirror. The undiffracted light from both of the modulators is blocked. The diffracted light emitted from the first and second Bragg cells passes through first and second imaging lenses respectively. The two diffracted light beams are then combined with an angular separation between beams. The combined beam is incident upon a square-law detector array which is at the image plane of the imaging lenses. Due to the square-law detection process, terms of low frequency biases and complex correlation on a spatial carrier develop.

Abstract: A clutch is disclosed having an input shaft and an output shaft and having alternate pairs of discs interfitting with each other. Half of the discs being attached to the input shaft and half to the output shaft. The discs are knurled on one side in a grooved pattern. The knurling is deeper at the inner radius than at the outer radius so that there is a major restriction to oil flow from the inner radius to the outer radius. The restriction of the grooves insures that the grooves are completely filled with oil during operation of the clutch.

Abstract: A synchronizing clutch made up of a quill shaft, a hub, a toothed sleeve for connecting the hub to the shaft and a clutch between the sleeve and the hub for synchronizing the speed of the hub with the speed of the sleeve prior to connecting the hub teeth to the shaft teeth. Drive pins are provided on the shaft for preventing the teeth from interfering at synchronization and an improved adjusting means and a retaining ring provide a space for the clutch discs so that the axial position of the clutch discs relative to the drive pins prior to synchronism is always precisely known.

Abstract: A gear coupling and oil actuated synchronizing clutch is disclosed. The oil is connected to the clutch by a static seal ring freely supported on the drive shaft, next to a shaft flange. The seal ring has a piston groove containing a piston ring adjacent the flange overlying a narrower groove in the flange. Engage oil in the static seal groove forces the piston ring against the flange and holes in the piston ring conduct oil to the flange groove and then to the disc pack and clutch actuating mechanism. The disc pack has a larger inlet than outlet so that the engage oil fills the pack introducting a viscous drag to the discs and initiating action of balking mechanism. Drive pins are advanced into kidney shaped holes where they form an interium connection after synchronism and before gear engagement so that the drive gears can freely register with the driven gear.

Abstract: The specification discloses a clutch assembly made up of a sleeve and a hub supported on each other for free rotation and being suitable for connecting a drive member to a driven member. The hub and sleeve have friction discs attached to them and the friction discs engage a pressure ring. A supply of oil under pressure is connected to the cavity that receives the clutch plate and when oil is admitted to the friction ring cavity it first fills this cavity then spills over into a cavity containing an actuating piston connected to the pressure ring where the oil forces the actuating piston together with the pressure ring into engagement with the clutch plates thereby forcing them into frictional engagement with each other. A reaction force against the clutch plate is provided by a pressure and adjusting ring from which a reaction force is transmitted to the clutch plate through a Belleville spring. By means of the adjusting ring, the pressure at which the clutch plates will slip can be adjusted.
