Title: System and process for automatic storage, enforcement and override of consumer do-not-call requests
Inventor: FOTTA KEITH A
IPC: H04M3/38
Filed: 1998-05-08
Granted: 2007-07-24
Abstract: A system and process for automatic storage, enforcement and override of consumer do-not-call (DNC) request include a control device for selectively blocking communication between a communication device and a destination over a communication medium. The control device is connected to the communication medium and to a database for storing identifiers of destinations for which communication is to be blocked. The communication device has an input mechanism responsive to a user to generate an identifier of the destination. The input mechanism is also responsive to an update signal indicating that the identifier should be added to the database or an override signal indicating that the blocked call should in fact be permitted, thereby overriding the blocking mechanism. The communication device is automatically updated with information stored in the database which may be used by the communication device to process further communication.

Abstract: A nozzle cap (10) is disposed downstream of a nozzle body (1) of a combustor for a gas turbine, an inner surface part (12) of which is of a conical shape diverging downstream to define a fuel-jet guide (17) for~ guiding fuel jet ejected from one or more nozzle holes (3) provided at the center of a downstream end surface of the nozzle body. Fuel ejected from the one or more nozzle holes smoothly runs along the fuel-jet guide without remaining there to join with a swirl stream (S) in a swirl path (9), and to burn without generating smoke. Air introduced into a first auxiliary air path (6) defined between the nozzle body and a partition (5) at a position upstream thereof passes through a second auxiliary air path (16) defined between a downstream end surface (2) of the nozzle body (1) and an upstream end surface (13) of the nozzle cap and reaches an entrance (19) of the fuel-jet guide. The air then flows along the fuel-jet guide to cool the nozzle~ cap and prevent the fuel ejected from the one or more nozzle holes from sticking to the nozzle cap.

Abstract: A transportable hauling container, such as a trailer of a tractor-trailer combination, has a rear portion that is configured in or convertible to a wedge shape. Movable portions are located at the rear sides of the trailer that can pivot inward toward a longitudinal centerline. Movable flaps also are located at the rear top of the trailer, which can pivot downward in alignment with the movable portions. The movable portions and flaps can be secured relative to each other in various combinations, thereby providing a more aerodynamic configuration of the trailer rear end. The container or trailer can be configured in such an arrangement, or be convertible from a standard configuration which also includes doors at the rear of the trailer, to a more aerodynamic configuration. A method is also disclosed, which includes operations for converting such a convertible trailer between the standard and aerodynamic configurations.

Abstract: A uniplanar dual strip antenna (400) that has a two-dimensional structure. T he antenna is comprised of a first and a second metallic strip (404, 408), each printed or etched on a thin planar substrate (412). T he first and second strips (404, 408) are separated by a predetermined gap (T) and are used as conductors of a two-wire transmission line. A coplanar waveguide (416, 1520) is coupled to the uniplanar dual strip antenna (400). The coplanar waveguide (416, 1520) is constructed by printing or etching metal on the substrate. The positive terminal (420, 1522) of the waveguide is electrically connected to the first strip. The negative terminal (424, 428) of the waveguide is electrically connected to both the first and second strips. The uniplanar dual strip antenna (400) according to the present invention provides an increase in bandwidth over typical quarter wavelength or half wavelength patch antennas. Experimental results have shown that the uniplanar dual strip antenna (400) has a bandwidth of approximately 8 - 20 % that is extremely desirable for PCs and cellular phones.

Abstract: The invention relates generally to a method and an arrangement for transferring information in a packet radio service.      Especially the invention applies to transferring delay sensitive data, such as speech and video data, in a mobile telecommunications system. It is an object of this invention to provide a solution, in which the physical connection of a packet radio service is kept reserved also during the passive periods of a session but the same physical resource can still be shared between multiple users. A basic idea of the invention is that the network is informed at the end of an active period, on whether a passive period follows the active period or if the connection can be released. When an active period starts after a passive period, the connection preferably reserves the packet data channel again, and possible other users of the channel are assigned to other channels.
