Patent number: 8095620Abstract: The present invention relates to a system and method for dynamic allocation of a resource. In particular, it concerns a system to dynamically designate a priority for a resource request and to allocate a resource, partially filling or completely filling the request. Partial filling of requests and conditional priorities allows maximum use of resources at low priority while protecting minimum access to resources Thus, the system and method of the present invention improve access and optimization of a Bandwidth On Demand (BOD) satellite communication system. Free resources are used as access channelsthat may be allocated to a user.Type: GrantFiled: June 13, 2002Date of Patent: January 10, 2012Assignee: Elbit Systems Land and C41-Tadiran Ltd.Inventors: Adam Rom, Zvi Ner

Publication number: 20110003543Abstract: A satellite broadcasting system for communication between a satellite hub and a range of ground stations in which a set having a predetermined number of MODCODS is available for data transmission from the satellite hub to the ground stations. Each MODCOD in use in the hub requires additional hub resources, and the system uses a MODCOD limiter for limiting the number of MODCODs in operation at a given time to a subset smaller than said predetermined number of MODCODS, thereby reducing overall resource usage.Type: ApplicationFiled: April 22, 2009Publication date: January 6, 2011Applicant: Elbit Systems Land and C41 - Tadiran Ltd.Inventor: Shaul Laufer

Patent number: 4614917Abstract: There is provided an indirect frequency synthesizer in the millimeter wave frequency range of 36 to 38.6 GHz. The synthesizer comprises a high performance frequency translation loop for operation in the microwave frequency range and contains a voltage-controlled oscillator, an automatic loop gain correction system and a sophisticated lock search system. The frequency translation loop is operable under a variety of conditions (temperature etc.) and overcomes the considerable difficulties which exist in this frequency range such as maintenance of constant optimum loop parameters, thus making it possible to utilize the entire frequency tuning range of the millimeter wave oscillator. As a result, the synthesizer has very satisfactory characteristics as regards noise and spurious frequencies products.Type: GrantFiled: April 17, 1985Date of Patent: September 30, 1986Assignee: Tadiran Ltd.Inventors: Michael Zelitzki, Yekutiel Josefsberg
