Abstract: Contrast Imaging apparatus and methods with Wavefront Coding aspheric optics and post processing increase depth of field and reduce misfocus effects in imaging Phase Objects. The general Interference Contrast imaging system is modified with a special purpose optical element and image processing of the detected image to form the final image. The Wavefront Coding optical element can be fabricated as a separate component, can be constructed as an integral component of the imaging objective, tube lens, beam splitter, polarizer or any combination of such.

Abstract: A multispectral X-ray imaging system uses a wideband source and filtration assembly to select for M sets of spectral data. Spectral characteristics may be dynamically adjusted in synchrony with scan excursions where an X-ray source, detector array, or body may be moved relative to one another in acquiring T sets of measurement data. The system may be used in projection imaging and/or CT imaging. Processed image data, such as a CT reconstructed image, may be decomposed onto basis functions for analytical processing of multispectral image data to facilitate computer assisted diagnostics. The system may perform this diagnostic function in medical applications and/or security applications.

Abstract: Disclosed is time keeping system for an employer. The system includes one or more time-keeping network appliances. Each of these appliances includes a small web server. The system also includes some form of employee interface which enables the employee to submit, and the time keeper to receive, identification information regarding the employee. One embodiment uses at least one of a card reader, punch key pad, bar code reader, or proximity badge reader. These devices are used to clock employees in and out. The system also optionally includes an audio-output device to give the employee audio feedback during clock in and an LCD to give the employee visual feed back. If a second network device is included in the system, it is automatically set up as a client of the original time keeper introduced into the system.

Abstract: A golf instructional device is provided for designating proper setup positioning for swinging a golf club and for monitoring the location of a user's eyes while swinging the club, such a mat being customized for an individual golfer. The device comprises a mat for providing a playing surface upon which foot positioning markers, a club positioning marker and a mirror are placed. The markers and mirror are designed to be removably attached to the mat surface to allow a golf instructor to indicate proper location and angle for the user to position themselves and the club which they are swinging. The mirror is of a chosen size such that when attached to the mat at the proper location, the user can observe their eyes while swinging the golf club. A wedge is also provided to be positioned underneath a portion of the user's rearward foot to train the user to maintain a near stationary rear leg during the backswing.

Abstract: Disclosed is a device and method for removing the lid of an inkjet cartridge. The device holds the cartridge within two jaws, which secure only the bottom of the cartridge. A driving mechanism is used to pop off the top of the cartridge in order that it may be refilled. The driver is J-shaped and has long and short prongs connected by a cross member. A screw within a bulkhead is used to push the driver from the back. This causes the long prong to bear against the top of the cartridge to remove it. The short prong assists in guiding the driver. A spring pushes back on the driver the further it is driven. This enables the user to retract the driving member once the top of the cartridge has been removed. A shelf is formed on all of the jaws of the holder. One jaw has an overhang portion which, with the shelf, forms a channel. Many commercially available cartridges are configured with a rib at their midsection. The shelf and channel act to receive this rib so that the cartridge may be held securely.

Abstract: The present invention provides improved Wavefront Coding imaging apparatus and methods composed of optics, a detector, and processing of the detected image. The optics are constructed and arranged to have the characteristic that the transverse ray intercept curves form substantially straight, sloped lines. The wavefront coding corrects for known or unknown amounts of “misfocus-like” aberrations by altering the optical transfer function of the imaging apparatus in such a way that the altered optical transfer function is substantially insensitive to aberrations. Post processing then removes the effect of the coding, except for the invariance with regard to aberrations, thereby producing clear images.

The sensor and microprocessor may integrate in clothing or in a watch worn by the person. Wireless signals may be generated to a remote base station or to a watch. Performance data may for example include speed, drop distance, airtime and power.

Abstract: A method and control system for forming workpiece surfaces with at least a portion being non-rotationally symmetric (i.e., axis asymmetric) is provided. In one aspect, a slow tool servo system is provided to fabricate a surface having at least an axis asymmetric portion, and optionally, a superimposed axis symmetric asphere or spherical portion. A workpiece is mounted on a spindle and a tool is mounted to a translatable tabletop surface. The z position of the contact point of the workpiece and working tool is determined as a function of the x position of the same contact point and as a function of the angle of rotation of the spindle about the spindle axis. By making the z position of the contact point a function of both the angle of spindle rotation and the x position, the lateral and longitudinal position of the working tool can be moved at designated spindle rotation angles to form a surface having both axis asymmetric and axis symmetric asphere or spherical portions.

Abstract: An optical lithography system that has extended depth of focus exposes a photoresist coating on a wafer, and includes an illumination sub-system, a reticle, and an imaging lens that has a pupil plane function to form an aerial image of the reticle proximate to the photoresist. The pupil plane function provides the extended depth of focus such that the system may be manufactured or used with relaxed tolerance, reduced cost and/or increased throughput. The system may be used to form precise vias within integrated circuits even in the presence of misfocus or misalignment.

Abstract: An alternating electric field is applied at an ice interface to generate a resistive AC current having a frequency greater than 1000 Hz in interfacial ice. Typically, a first electrode and a second electrode proximate to the interface are separated by an interelectrode distance of about 50 ?m to 500 ?m. An AC power source provides a voltage of about 10 to 500 volts across the electrodes in order to create the alternating electric field. Interfacial ice converts capacitive AC current into resistive AC current, which generates Joule heat in the interfacial ice.

Abstract: A wire guard for filling an opening in an electrical box, to protect contents contained therein, includes a plate having a circumferential wall projecting outward from the plate at a defined angle. The wall extends for a length of a perimeter of the plate, contacting an interior surface of the electrical box when the plate fills the opening. At least one bracket of the wire guard surrounds a tab formed in the electrical box. Further, an aperture in the bracket aligns with a bore hole in the tab. A mechanical fastener, e.g. a screw, may be inserted into the aperture to engage with the bore hole of the tab, thereby fastening the wire guard to the electrical box. A screw driver or other tool, inserted into an aperture in the plate, may be used to extract the wire guard from the electrical box after use.
