Abstract: A low-cost, flexible, high performance system and method comprises a means for interfacing a code division wireless system to a fast packet-switched network for transmission over a core network to a destination terminal user via a destination access node and a destination access radio port. The method is for code division switching at an originating terminal, the originating terminal being located within a microport cell of a terrestrial wireless network at a given instant in time, where said network interfaces with an access radio port, and comprises the steps of spreading a transmission signal by a PN-code assigned to an intended receiving port, inserting an identifier of a few bits for identifying a user, spreading a payload data signal by an orthogonal code, spreading the orthogonal spread payload data signal by the PN-code associating the user with payload data, modulating the PN-code spread transmission signal and the twice-spread payload data signal, and forwarding the modulated PN-code spread transmission signal and the modulated twice--spread payload data signal to an access radio port. The code division switching system at an originating terminal is described, the originating terminal being located within a microport cell of a terrestrial wireless network at a given instant in time, where said network interfaces with an access radio port, comprises a first spreader for spreading a transmission signal by a PN-code assigned to an intended receiving port, a second spreader for spreading a payload data signal by an orthogonal code assigned to a receiving terminal user to which the payload data signal is directed, the payload data signal being further spread by the first spreader, a means for forwarding the PN-code spread transmission signal to an access radio port and a means for forwarding the twice-spread transmission signal to an access radio port.

Granted: 2006-03-28
Abstract: A towed rotary cutter includes a self-leveling hitch equipped with a parking stand mounted in a centered position beneath the hitch. Through the operation of the leveling links, the hydraulic-lift cylinder that is used for raising and-lowering the ground wheels of the cutter relative to the cutter frame is also used to manipulate the hitch, once the parking stand is placed in its park position, so as to remove the weight of the hitch from the tractor drawbar when unhitching the tractor from the rotary cutter, or to place the hitch clevis at the correct height for connecting it to the tractor drawbar when hitching the cutter to the tractor. In a first embodiment, the parking stand is constructed for use with a hitch having a feature for automatically maintaining the clevis in a horizontal attitude. In a second embodiment, the parking stand includes a clevis support which is oriented for supporting the clevis in a horizontal attitude when the parking stand is in its park position, but is moved so as to permit free pivotal movement of the clevis when the parking stand is in its stored position.

Title: Vacuum cleaner having a cyclone-type dust-collecting apparatus
Inventor: OH JANG-KEUN
IPC: B01D45/14
Filed: 2002-11-15
Granted: 2007-08-28
Abstract: The cyclone-type dust collecting apparatus for a vacuum cleaner can reduce reverse flow of dirt and kill any bacteria in the dirt-collecting receptacle.   The cyclone-type dust-collecting apparatus has a protruding flow path formed on the front side of the cyclone body and a lamp-positioning groove depressed inwardly at one side of the dirt-collecting receptacle for an ultraviolet lamp disposed in the cleaner body to apply ultraviolet rays radiated into the dirt-collecting receptacle. Accordingly, various bacteria inside the dirt collecting receptacle can be killed as the ultraviolet lamp disposed in the lamp positioning groove of the dirt collecting receptacle continuously applies the ultraviolet rays into the dirt collecting receptacle while the cleaner is on. Moreover, reverse flow of the dirt through the protruding flow path can be reduced as the storage level of the dirt stored near the protruding flow path of the dirt collecting receptacle is lowered and the space between the dirt near the protruding flow path of the dirt collecting receptacle and the cyclone body is expanded.
