A method and system of interference lithography (also known as interferometric lithography or holographic lithography) which utilizes phase-locked, scanning beams (so-called scanning beam interference lithography, or SBIL). The invention utilizes a high-precision stage that moves a substrate under overlapped and interfering pairs of coherent beams. The overlapped beams interfere, generating fringes, which form a pattern “brush” for subsequent writing of periodic and quasi-periodic patterns on the substrate. The phase of the fringes in the overlapped region is phase-locked to the motion of the precision stage. The invention includes methods for forming, overlapping, and phase-locking interfering pairs of beams on a variety of substrates; methods for measuring and controlling the period, phase, and angular orientation of fringes generated by the overlapping beams; and methods for measuring and controlling the effects of stage mechanical and thermal drift and other disturbances during the writing process.

A camera holding assembly that is configured to hold a plurality of cameras in a predetermined orientation includes a support having a plurality of receptacles. Each of the receptacles include at least one feature enabling a camera to be releasably retained therein as well as at least one and preferably at least three attachment features configured for enabling the camera holding assembly to be secured to another object. The receptacles are oriented about the support so that each camera, when loaded into the defined receptacles, is aimed in a different angular orientation. Images obtained from each retained camera can be stitched to create either a composite 360 degree×180 degree full spherical image or a composite 360 degree composite image of a scene of interest.

A display system includes a base, a pair of electronic displays, and an arm assembly that supports the displays from the base in vertical or horizontal registration. In one implementation, the arm assembly is a single telescopic member that rotates relative to the base and locks in vertical and horizontal orientations, the displays rotate relative to the member between corresponding extreme angular positions in which the operative angular orientation of the displays relative to horizontal is maintained, and the length of the member is adjusted to minimize separation of the displays. In another implementation, the arm assembly has separate arms rotating about vertically spaced axes and linked to minimize the separation of the displays automatically when vertically or horizontally registered. In a simple implementation, the arm assembly is a rigid arm that releasably attaches to the base only in vertical and horizontal orientations, the displays mounted releasably to the arm in pre-defined angular orientations that preserve their operative angular orientation, and one display can be connected to the arm at spaced apart position to adjust separation of the displays.

Optical devices for guiding illumination are provided each having a body of optical material with staircase or acutely angled ramp structures on its top surface for distributing light inputted from one end of the device from the front exit faces of such structures along certain angular orientations, while at least a substantial portion of the light is totally internally reflected within the body until distributed from such front exit faces. Optical devices are also provided each have a body of optical material having a bottom surface with acutely angled ramp structures and falling structures which alternate with each other, such that light is totally internally reflected within the device until reflected by such ramp structures along the bottom surface to exit the top surface of the device or transmitted through the ramp structures to an adjacent falling structure back into the device. Acutely angled ramp structures may be provided on both top and bottom surfaces of optical devices for distributing light along such top surface. Illumination apparatuses are also provided using such optical devices.

A head-wearable display includes a collimated light source, a beam steering mechanism, and a synchronization controller. The collimated light source selectively emits collimated light. The beam steering mechanism is optically coupled to receive the collimated light and angularly scans the collimated light between beam steering states that each redirect the collimate light to a different angular direction along at least one angular dimension. The beam steering mechanism is coupled to scan the collimated light across an eyebox. The synchronization controller is coupled to the collimated light source and the beam steering mechanism to synchronize selective emission of the collimated light from the collimated light source with the beam steering states of the beam steering mechanism to repetitiously draw an image in the eyebox.

An articulating fore grip adapted for retrofit attachment to a rail-like support structure of an existing firearm. The fore grip comprises a base member which is slidably attachable to and selectively positionable along the rail of the firearm. The base member is outfitted with a locking mechanism which is operative to selectively maintain the base member in a prescribed position relative to the rail. The fore grip further comprises an adapter member which is rotatably connected to the base member, and a handle member which is pivotally connected to the adapter member. The rotatable and pivotal connection of the handle member to the base member effectuated by the adapter member allows the handle member to be selectively positioned in a multiplicity of differing angular orientations relative to the rail of the firearm, and further allows the handle member to be selectively moved between a fully deployed position and a fully collapsed position.

An adjustable putter head for a golf putter is designed having an elongated line of sight marking on a top surface of the putter head to aid in aligning the putter head in a putting direction toward a target point, and a putter face which is pivotally connected to the putter head to allow selective adjustment of an angular position of the putter face relative to the line of sight for purposes such as adjusting a face angle orientation to compensate for improper putting strokes, or lining up breaking putts using the line of sight to aim the putt at the hole as a fixed target while adjusting the face angle orientation to align the ball striking face square to an off-line direction of intended ball movement.

A vehicle light can include a light emitting diode (LED) serving as a light source and an optical system for controlling a light distribution pattern of the light beams from the LED light source utilizing a light guide (such as a lens body having an inner reflecting surface). The vehicle light can project illumination light with a low beam light distribution pattern. The vehicle light can include an LED light source and a lens body serving as a light guide. The lens body can include a light incident surface, a reflecting surface, and a light exiting surface. The LED light source can have a rearmost end light emitting point from which light beams are emitted to form a bright-dark boundary line. Among the light beams, perpendicularly incident light beams not subjected to refraction can be projected toward the bright-dark boundary line while obliquely incident light beams that are subjected to refraction can be corrected to be directed in a lower angular direction than the bright-dark boundary line and to be mixed with the other light beams, thereby preventing color shading of illumination light from the vehicle light.

A light fixture having a light source, first and second heat sinks with corresponding first and second thermal interfaces having complementary curved surfaces, and a linkage having cams, and springs to create contact pressure between the thermal interfaces when the light fixture is in an operation mode and to permit movement between the thermal interfaces when the light fixture is in an adjustment mode. When the light fixture is in operation mode, the first and second heat sinks work in combination to provide a highly effective heat dissipation system. When the light fixture is in adjustment mode, the separation created permits the light source to move along an adjustment path to change the angular direction of the light emitted and to rotate about a rotational axis, providing a full range of directional lighting orientations.

Upon expanding in the transverse direction, the first bladder applies an angular traction to the cervical spine. Upon expanding in the angular direction, the second bladder bears angularly against the back of the user's upper thoracic region.

A fully adjustable hunting tree stand comprising a mounting base; a support member; a seat; and a platform. The mounting base and the support member axially interconnect for independent rotation about a common axis. The platform attaches to the support member at an end thereof, with the seat attaching to the support member at an opposite end thereof. The mounting base attaches to a tree of any angle, being aligned in the same angular direction thereof. The support member adjustably rotates about the mounting base and is secured in a position, which enables the platform and the seat to achieve a leveled position, regardless of what angled position the mounting base is placed.

An improved rotary servovalve system employs a rotary magnetic solenoid having an armature that includes at least one permanent magnet. The armature is rotatable relative to a stator formed as an electromagnet which is energizable to create alternative electromagnetic fields having opposite polarities from each other. When deenergized, the stator allows the armature to return to a neutral, null position from positions of extreme rotation in opposite angular directions due to the magnetic force of the permanent magnet of the armature. The armature is coupled to carry a movable valve element in angular rotation therewith, so that flow through the servovalve of the system can occur in alternative directions. Also, the valve element is biased toward a position in which all of the valve ports are closed when power is removed from the rotary solenoid. The control circuit employed in the rotary servovalve system expands the bandwidth of response of the solenoid actuator by compensating for frequency variations in the input command signal and in the feedback signal. This compensation is achieved utilizing a combined proportional, integral, and differential amplification circuit. Also, imbalance of fluid forces within the servovalve mechanism can be avoided by utilizing a pair of inlet orifices, a pair of outlet orifices, a pair of first fluid control orifices, and a pair of second fluid control orifices. The orifices within each pair are located on opposite sides of the valve housing from each other.
