Abstract: Techniques for identifying a trusted SSID for a wireless network are disclosed. Prior to establishing a connection with a wireless network, a first network message is received from a first access point (AP) identifying a first service set identifier (SSID) associated with a first wireless network, a second network message is received from a second AP identifying a second SSID associated with a second wireless network, and a visual similarity is determined between a first visual representation of the first SSID and a second visual representation of the second SSID. The second SSID is designated as suspicious based on the determined visual similarity.

Abstract: A distance measurement location control system for guiding a helicopter pilot to locate powerline marker ball positions with respect to longitudinal displacement. A location control assembly communicates with a microprocessor module (MCU) onboard the location control assembly. A computer device is configured to receive and transmit setup data from and to the location control assembly. A GNSS module onboard the location control assembly is electrically connected to the MCU. A display onboard the location control assembly is connected to a first serial data line from the MCU to receive GNSS data. A global satellite communication network module onboard the location control assembly is electronically coupled to a second serial data line from the MCU to provide flight information. The display operates to dynamically guide a helicopter pilot to a number of powerline ball locations in a precise manner.

Abstract: Aspects of the present invention relate to systems and methods for device-independent portable session synchronization between multiple devices connected to a server system. Some aspects relate to the use of a real-time-request (RTR) database construct for managing communication between devices. Some aspects relate to management logic, which manages entries in the RTR database construct. In some aspects, database construct entries relate to device identification, session identification, device requests and device responses.

Abstract: In color graphics printing, incompatible inks, such as true black and color inks, tend to bleed across color field boundaries. Moreover, in four-color systems, there is a discontinuity in the physical color gamut, as distinguished from the logical color gamut, associated with the redundant color. A method is disclosed for alleviating both problems by adjusting image data prior to dithering. The method slightly shifts the logical color indicated in the image data so as to avoid the discontinuity that arises with neutral colors. Preferably, in a four-color printing system, yellow is depleted in the image data, so that after dithering, more dots of blue ink are printed in a given area than would be printed otherwise. For each pixel, the amount of correction is inversely related to the color saturation. The presence of blue ink dots within the substantially black field reduces bleed along the field edges.

Abstract: A method for alleviating a problem in color graphics printing that incompatible inks, such as true black and color inks, tend to bleed across color field boundaries includes depletion of yellow in the image data so that more blue content is present in the image data. For each pixel, the amount of correction is inversely related to the color saturation and a corresponding correction factor related to the amount of correction is selected to be less than or equal to a preselected maximum correction factor. The presence of blue ink dots within a substantially black field, resulting from the depletion of yellow, reduces bleed along the field edges.

Abstract: A method of halftoning a digital gray scale image is disclosed that utilizes a point by point thresholding comparison to a novel diagonal correlation dither matrix. The new dither matrix forces diagonal correlation of adjacent dots in the output image while maximizing dispersion of dots, thereby producing visually unobtrusive output dot patterns. The matrix is generated according to a spatial domain cost function that determines a cost value for each candidate pixel based on respective radial distances and relative angles between a candidate pixel and the ON pixels in the matrix such that unit diagonals are favored over placement of vertically or horizontally adjacent dots.

Abstract: Methods are disclosed for improving output image quality and reducing processing time in digital halftoning systems. The direction of processing each scan line of a source image is selected with blue noise, rather than the tradional raster scan sequence, to reduce directional and start-up anomalies. Source image pixel gray values are adjusted by means of imposed matrices, prior to error diffusion, in order to minimize distracting patterns and other anomalies in the output image. Error diffusion threshold values are modulated with blue noise, and the average threshold value reduced to reduce start-up delay. Finally, error terms in the error diffusion process are diffused according to a new three-weight filter. The three-weight filter substantially reduces error diffusion processing time, without sacrificing output image quality when used in combination with the modulated error diffusion threshold values.
