Abstract: Disclosed are further improvements of AmbiLight Displaying Arrangement, a lighting or illumination system that has been introduced to enhance viewing experience. This is achieved by providing light sources (20) that create multiple colors next to at least one side of the screen (10) of the display device or arrangement, each of the multiple colors being 5 adapted to the video contents at a spatially corresponding region (50) of the screen (10). In one embodiment the lighting or illumination system can have an improved construction wherein a reflector (60) has a window section (65) enabling the light from the light sources (20) to be split into two. Half or more of the light is directed to the background (30) of the display device and half or less of the light is directed to the bezel diffuser (70), i.e. to the 10 front of the display device.

Abstract: Methods and systems for vector combining power amplification are disclosed herein. In one embodiment, a plurality of signals are individually amplified, then summed to form a desired time-varying complex envelope signal. Phase and/or frequency characteristics of one or more of the signals are controlled to provide the desired phase, frequency, and/or amplitude characteristics of the desired time-varying complex envelope signal. In another embodiment, a time-varying complex envelope signal is decomposed into a plurality of constant envelope constituent signals. The constituent signals are amplified equally or substantially equally, and then summed to construct an amplified version of the original time-varying envelope signal. Embodiments also perform frequency up-conversion.

Abstract: A process for pre-calibrating illumination sources permits illumination light intensities to be set to a near optimal level during training of an optical inspection system. Applicants have found that the illumination source intensities for a category of illuminators are sufficiently constant from machine to machine that the data collected during calibration of an illumination source on a machine using a particular type of source may be used on other machines of the same type using the same type of illumination source when combined with the reticle light intensity data for different zoom magnification's of the particular machine being used. That is, using known data for particular machine and the illumination source light intensity data for the same type of machine and illumination source permits accurate presetting of an illumination source.

Abstract: A method for correcting higher order aberrations in an eye requires Laser Induced Optical Breakdown (LIOB) of stromal tissue. In detail, the method identifies at least one volume of stromal tissue in the eye, with each volume defining a central axis parallel to the visual axis of the eye. Thereafter, a pulsed laser beam is focused to a focal spot in each volume of stromal tissue to cause LIOB of stromal tissue at the focal spot. Further, the focal spot is moved through the volume of stromal tissue to create a plurality of incisions centered about the respective central axis of the volume. As a result, a predetermined selective weakening of the stroma is caused for correction of the higher order aberration.

Abstract: In a method of recording and reading optical information in a recording medium using holography, a first recording operation is performed for recording optical information in a first recording region in an overlapping manner by allowing a reference beam and a signal beam with data loaded to interfere with each other in the first recording region, the reference beam being angularly multiplexed at predetermined intervals. Furthermore, a second recording operation is performed for recording optical information in a second recording region adjacent to the first recording region in an overlapping manner by allowing the reference beam and the signal beam to interfere with each other in the second recording region, the reference beam being angularly multiplexed between the predetermined intervals. Consequently, optical information can be recorded so as to easily detect and determine a selected reproducing beam, thus increasing the reading efficiency of the optical information.

Abstract: Dynamic load balancing of network traffic is achieved using one or more access points by using a server-centric approach where rules are applied to attributes and characteristics observed by the server which form a profile of wireless clients accessing the network, such as in-car video systems. In various illustrative examples, priorities are assigned to in-car video systems and data files stored therein to which the server applies rules to responsively invoke commands performed by the in-car video systems to balance the uploading of data files to the server. The commands, when executed, allow high priority data files, or data files from high priority in-car video systems or users to be uploaded first, while lower priority data files or users are put on hold. In other illustrative examples, in-car video systems are commanded by the server or forced to roam between access points having overlapping coverage but operating on different non-interfering channels.

Abstract: A wavefront sensor is integrated with a surgical microscope for allowing a doctor to make repeated wavefront measurements of a patient's eye while the patient remains on an operating table in the surgical position. The device includes a wavefront sensor optically aligned with a surgical microscope such that their fields of view at least partially overlap. The inclusion of lightweight, compact diffractive optical components in the wavefront sensor allows the integrated device to be supported on a balancing mechanism above a patient's head during a surgical procedure. As a result, the need to reposition the device and/or the patient between measuring optical properties of the eye and performing surgical procedures on the eye is eliminated. Many surgical procedures may be improved or enhanced using the integrated device, including but not limited to cataract surgery, Conductive Keratoplasty, Lasik surgery, and corneal corrective surgery.
