Abstract: Metadata associated with at least one field defined in a user interface is identified. The metadata associated with the field defined in the user interface is processed to identify at least one characteristic of the field defined in the user interface. Based on the characteristic(s), a test string is generated for use as an input into the field defined in the user interface to perform validation on the field.

Abstract: A method and apparatus for detecting objects. A first plurality of electromagnetic signals having a first frequency and a second plurality of electromagnetic signals having a second frequency are transmitted. At least one of the first frequency and the second frequency is changed through a range of frequencies. A delayed difference frequency signal substantially equal to a difference between the first frequency and the second frequency is monitored for. The delayed difference frequency signal is generated by an object having non-linear electrical characteristics in response to the object receiving the first plurality of electromagnetic signals and the second plurality of electromagnetic signals. A range measurement is generated for the object by comparing the delayed difference frequency signal and an undelayed difference frequency signal. The undelayed difference frequency signal is substantially equal to the difference between the first frequency and the second frequency.

Abstract: A composite dipole array assembly can have a composite dipole array defined by a plurality of antenna elements and a plurality of non-linear element electrically interconnecting pair of the antenna elements. A reflector can be configured to reflect electromagnetic energy toward the antenna elements. A lens can be configured to focus electromagnetic energy upon the antenna elements. In this manner, the efficiency of the composite dipole array is enhanced.

Abstract: A method and apparatus for a focal plane array with serial, variable bit width analog to digital converter. The focal plane array includes a plurality of pixels and a dynamically reconfigurable analog to digital converter. The controller determines a number of digital output bits required to generate digital output at a selected conversion resolution. A sample and hold circuit holds an analog voltage from a pixel to form a captured analog signal. A one-bit converter stage processes an instance of a captured analog signal to generate an output bit. The controller iteratively processes a residue voltage through the one-bit converter stage a number of times required to generate the number of digital output bits to form a digital output with the user defined conversion resolution.

Abstract: A synthetic aperture radar (SAR) system includes a transmitter capable of transmitting a pair of signals that each have a predetermined frequency in the optical band of the electromagnetic spectrum. The predetermined frequency can be selected, for example, to provide a level of resistance to at least one of movement of the target, target vibration and optical path length variations, and can further be selected based upon a predefined range and azimuth resolution. The SAR system also includes a receiver capable of receiving at least a portion of the pair of signals that has been reflected off of a target. In this regard, the receiver is capable of processing the reflected portion of the pair of signals based upon a difference frequency between the transmitted pair of signals.

Abstract: A tetrahedronal packaging machine packaging liquids which has a package-forming member mounted on each heat jaw to maintain the shape of the package being filled. The package-forming member is spring loaded to allow the forming member to be rotated to a second position to provide a different size package of liquid fill.

Abstract: A service lift stand apparatus includes a support frame assembly, a lift platform assembly, and a drive arrangement. The support frame assembly is composed of a horizontal lower base and a vertical mast mounted in an upstanding orientation on the base. The lift platform assembly is mounted to the upright mast for reciprocal movement vertically therealong. The drive arrangement is supported on the support frame assembly and is operable to movably drive the lift platform assembly in upward and downward directions along the upright mast away from and toward the base of the support frame assembly. The drive arrangement includes a vertical drive screw shaft rotatably mounted to the mast and coupled to the lift platform assembly for driving the lift platform assembly vertically along the mast, and a drive motor mounted on the base and having an output drive shaft intercoupled to the screw shaft.

Abstract: A service lift stand apparatus includes a lift assembly, a mast assembly, a base assembly and a ramp assembly. The lift assembly includes a pair of lift arms which each mount a pair of individual support pads. The lift assembly is supported by the mast assembly with the lift arms extending in a cantilever fashion from the mast assembly for movement between a lowered loading and unloading position and a raised servicing position. The lift arms and support pads are adjustable to match different vehicle wheelbase sizes. The base assembly includes an adjustable platform, and the ramp assembly is adjustable and can be located at either end of the platform for driving the vehicle onto the apparatus at either end thereof. Also, the ramp assembly is located in spaced relation to the platform to accommodate nesting of the lift arms and support pads along the opposite platform ends in the lowered loading and unloading position of the lift assembly.

Abstract: Aligning a stable ring resonator by the use of an inversion mechanism ins the resonator and a pair of anti-symmetric masks. Each mask has opaque and clear parts and the masks are anti-symmetric in that, in use, one mask is positioned so that its opaque and clear parts are anti-symmetric to the opaque and clear parts of the other mask when it is in position. One mask is placed between the radiation source and the beam splitter while the other mask is placed between the beam splitter and the focal plane on which the two beam portions created by the beam splitter focus. One beam portion is directly reflected from the beam splitter and the other portion is transmitted into the resonator and is inverted while following a beam path within the resonator before being outcoupled through the beam splitter in a much weakened state.

Abstract: A method and apparatus for testing an optical system 64 having an optical axis and a desired optical wavefront. A hologram is formed containing a recording of the desired optical wavefront. The hologram is located on the optical axis. When the hologram 50 is played back, the desired optical wavefront 62 is produced and directed toward the optical system 64. Wavefront 62 is retroreflected from the optical system 64 containing any of the system's aberrations. The retroreflected wavefront 66 is then passed through the hologram. A reference wavefront 60 is produced which is substantially conjugate to the desired optical wavefront. The reference wavefront 60 interferes with the retroreflected desired optical wavefront 66 thereby producing an interference fringe pattern characterizing the optical system under test.
