Title: Variable displacement hydrostatic drive for tractors
Inventor: CHORNEY HARVEY JOHN
IPC: F16H57/04
Filed: 1999-08-12
Abstract: A splitter gearbox for a four wheel drive, hydrostatically driven tractor integrates both the input drive train and the output drive train into a single gearbox. The drive mechanism eliminates the need for a separate mechanical gearbox by establishing pre-set fixed displacement settings that are electronically controlled along with the variable displacement of the hydrostatic motor and hydrostatic pump, to provide a smooth power shift through all ranges without requiring the tractor to stop. The drive mechanism is configured so that essentially all components are individually controlled so that the entire power generated by the tractor engine can be diverted to any one of the traction drive, the PTO mechanism, the auxiliary hydraulic drive or, to a somewhat lesser extent, the tractor hydraulic system. The splitter gearbox is mounted to the rear axle housing to allow the sharing of a common oil sump. The input gear set and the output gear set are also within the same common lubrication sump within the splitter gearbox.

Title: Mobile networks using atm switching
Inventor: OLKKONEN MIKKO
IPC: H04W88/14
Filed: 1998-03-19
Abstract: The invention relates to telecommunication networks and particularly to mobile networks using Asynchronous Transfer Mode (ATM) transmission systems. The invention also relates to the control of mobility and call control functions in ATM systems. According to the invention, a network element (MSC/BSC) of a telecommunication network, such as a mobile network, which in a conventional telecommunication network architecture ensures the switching of circuit-switched connections, is provided with an ATM switching function.  ATM switching functions are controlled with the same call and switching control operations (31) that are conventionally used e.g. for the control of a TDM switching field (32) in a PLMN network element. In a minimum implementation, an ATM switching field (301) provided with a suitable control interface (30) is simply arranged in place of or parallel with the TDM switching field. The switching network element thus becomes an ATM network node of a physical or a logical interface layer. PLMN level signalling, mobility management and call control are implemented using solutions offered by existing mobile networks and current PLMN network elements.

IPC: H04N5/913
Filed: 1999-11-24
Abstract: A copyright protection method and apparatus, an output method and device, and a recording method and device for protecting information signals that are transmitted and stored in both a baseband signal status and a compressed encoded data status are provided. The method includes the stops of superimposing a first copyright protection information as a digital watermark on a signal in a baseband state, and compression encoding the signal in the baseband to form an information signal in a compressed encoded data state. The signal in the baseband and the signal in the compressed encoded data are then transmitted from a first apparatus to a second apparatus. The second apparatus determines whether rewriting of the first copyright protection information superimposed on the signal in the baseband and the signal in the compressed encoded data state is necessary, and if it is determined that rewriting of the first copyright protection information is necessary, rewriting the first copyright protection information as a digital watermark on the signal in said baseband state only.
