  • METHOD AND SYSTEM FOR REDUCING UPLINK NOISE IN WIRELESS COMMUNICATION SYSTEMS
    Publication number: 20090054105
    Abstract: A method and system for reducing the overall noise floor in a wireless communication system, subsystem or network are disclosed, which reduces the output gain levels of specific uplink antenna transmitters during non-signal time periods (e.g., rest mode) when no communication signals are being conveyed between the mobile unit(s) and base station involved. The output gain level of each such uplink antenna's transmitter is decreased by a predetermined amount, which reduces the noise contribution of that uplink antenna, but also maintains the gain at a high enough level so that a signal can still pass from a mobile unit to the base station via that link, for example, during a call initiation attempt.

  • Method for Identifying Soiling On a Transparent Screen
    Publication number: 20090046148
    Abstract: Camera for identifying soiling on a protective screen. The camera is focused on a scene behind the protective screen and can be used to identify soiling and for other applications, e.g. to identify driving lanes and/or to identify objects. Soiling is identified merely by evaluating frames recorded in succession, artificial reference frames or reference objects are not required. A prerequisite for a successful measurement is that the relative speed vrel of the camera and of at least one recorded object in the surroundings is not equal to zero and its trajectory is predicted in the depiction. By comparing the relevant frame sections, possible soiling on subregions of the protective screen is identified.

  • DELAY MANAGEMENT FOR DISTRIBUTED COMMUNICATIONS NETWORKS
    Publication number: 20090046586
    Abstract: A method for programming the delay for a node in a communication system is disclosed. The node receives a selected delay value and a signal path delay value indicating a delay for signals communicated to the node. The signal path delay comprises an aggregation of transport delays calculated by each node for segments of the communication system between the node and a host node. The method further calculates an additional delay necessary to meet the selected delay value.
