20100238297 | METHOD AND APPARATUS FOR COMPENSATION FOR SKEW IN VIDEO SIGNALS - A system for compensating for skew in a color video signal transmitted by a cable having multiple conductors is described. A test pulse signal (e.g. a 2 MHz signal) is inserted into the color components (e.g. RGB) of the video signal during time periods in each frame when the RGB video signals are inactive, such as within 300 μs after the V sync signal. After transmission over the cable, the RGB components with the inserted test signal are delayed relative to each other using a delay line in cooperation with a control circuit. The delay line generates detect signals by detecting relative delays of the test signal pulses inserted in the RGB components. The control circuit controls the amount of delay in the delay line based on the detect signals, so that the RGB components in the video signal outputted by the delay line are synchronized. | 09-23-2010 |
20110057881 | KVM MANAGEMENT SYSTEM AND METHOD OF PROVIDING ADAPTABLE SYNCHRONIZATION SIGNAL - Disclosed is a KVM management system and method of providing synchronization signal adaptable depending one user's demand. The KVM management system includes a first module and a second module. The first module converts a first type of synchronization signal selected from a first group of synchronization signal combinations into a transitional signal. The second module converts the transitional signal into a second type of synchronization signal selected from a second group of synchronization signal combinations for the display. The transitional signal may be a composite synchronization signal combines one of red, green, blue video signals from the computer and carried on at least one pair of wire in an Ethernet network cable. The type of transitional signal can be predetermined by adjusting a first register stored in the first module. The second type of synchronization signal can be predetermined by adjusting a second register stored in the second module. | 03-10-2011 |

20140372544 | System and Method for Establishing 2-Way Communications Between an App and a Browser - A method is provided for receiving an instant message from a first user on a device of a second user irrespective of the device's installed applications or the second user's online status. A text message (addressed by the phone number of the second user's device) is received on the second user's device. The text message includes a link with a permanent unique token. When the link is actuated, a session is established of a dedicated web page on the second user's browser. The web page has a URL containing the permanent unique token. The instant message from the first user to the second user is displayed on the web page. The second user is then permitted to send a reply message to the first user via the web page. A server for enabling communication of an instant message is also provided. | 12-18-2014 |
20150038131 | System and Method for Simplifying Mobile Device Account Creation and Verification - A method is provided for establishing a verified user account record for a user using a device. A text message is received on the user's device addressed by phone number. The text message includes a custom URL. When the user actuates the custom URL from the device, a session is established of a dedicated web page on the user's browser, and the Device ID of the device is passed together with the phone number for storage in a non-transitory record associated with the user. | 02-05-2015 |

20100117914 | GNSS ANTENNA WITH SELECTABLE GAIN PATTERN, METHOD OF RECEIVING GNSS SIGNALS AND ANTENNA MANUFACTURING METHOD - An antenna is provided for GNSS and other applications and includes an adjustable-height vertical support PCB mounted on a ground plane and mounting a crossed-dipole radiating arm element assembly. The gain pattern of the antenna can be varied by constructing the vertical support PCB with different heights or adjusting the height and gain pattern in the field. Vehicles with significant pitch and roll can be provided with low-horizon tracking capability by providing a high-profile antenna configuration. Alternatively, low-profile configurations provide steeper gain pattern rolloff at the horizon for maximal multipath rejection and high accuracy. The droop angles of the radiating arm elements are also adjustable for varying the gain pattern and beamwidth. A matching and phasing network is connected to the radiating arm elements and provides a relatively constant input impedance for the various antenna configurations. Alternative aspects of the invention have different configurations of the radiating arm elements and ground planes. | 05-13-2010 |
