Abstract: An imaging method for imaging a region of investigation of an object comprises the steps of generating an energy input beam with an energy beam source, irradiating the region of investigation with energy input beam components of the energy input beam along a plurality of projection directions, the energy input beam components being formed with a frame mask being arranged between the energy input beam and the object and including frame mask windows, measuring first integrated attenuation values of the energy input beam components with an outer detector device arranged outside the frame mask, measuring second integrated attenuation values of the energy input beam components with a frame mask detector device being arranged on an inner surface of the frame mask, and reconstructing an image of the region of investigation based on the first and second integrated attenuation values. Furthermore, an imaging device for imaging a region of investigation of an object is described.

Abstract: A method of extending telecommunications service, wherein the method is implemented in an extension application server. The extension application server is coupled for data communications to a customer data source and to a telecommunications server. The telecommunications server includes, installed and operating upon the telecommunications server, a multiplicity of telecommunications extension services. The method of extending telecommunications service includes receiving, in the extension application server, from a requesting telecommunications extension service in the telecommunications server, a telecommunications service request; preparing, in dependence upon information from the customer data source, a response to the telecommunications service request; and transmitting the response to the requesting telecommunications extension service.

Abstract: A synchronization tracking device and method in a code division multiple access (CDMA) receiver including oversampling received signals corresponding to a plurality of chips at a predetermined speed and sequentially storing the oversampled signals in a received signal shift register unit; sequentially storing pseudo noise codes generated in a pseudo noise code generator in a pseudo noise code shift register unit in a chip unit; correspondingly multiplying the output data from the received signal shift register unit and the pseudo noise codes outputted from the pseudo noise code shift register unit by means of a plurality of multipliers; adding the data outputted from the plurality of multipliers and storing the added result as the phase information and energy value for one path; repeatedly performing the above procedure until the phase information and energy values for all paths are stored; and selecting the path corresponding to a largest value in the stored phase information and energy values for all paths

Abstract: A communication and refund center comprises a lockable cabinet structure having an access panel disposed on the cabinet structure cooperating to form a sealed enclosure when the access panel is engaged with the cabinet, a power supply to the interior of the cabinet, a coin chute accessible from the exterior of the cabinet structure, a coin magazine comprising a coin sleeve and a remotely actuated coin solenoid disposed above the coin chute, a telephone dialer, a digital voice modulator connected with and operative in response to the telephone dialer, a relay circuit operatively associated with the voice modulator and the coin solenoid, the relay circuit operating the coin solenoid in response to commands from the voice modulator to provide a specified number of coins to the coin chute. A modular mounting plate carries the power supply, telephone dialer, and voice modulator.

Abstract: A method for simultaneously forming a flat display panel and bonding to a printed circuit board is disclosed in which a silicon wafer is first supplied and then coated with an alignment layer, a multiplicity of spacers are then mounted to the wafer before it is severed into a multiplicity of dies. A frame seal is then applied to the periphery of the die, while a multiplicity of metal leads is formed on the die for electrical communication with a multiplicity of thin film transistors. A glass plate is then assembled to the silicon substrate by the frame seal, while simultaneously bonded to a printed circuit board in a bonder apparatus under pressure by utilizing a conductive material such as silver paste, an anisotropic conductive film or an isotropic conductive adhesive.

Abstract: A public telephone with a cash payment function is connected to a server of a banking agency through a telephone network and verifies whether a card, such as credit card, inserted by a user is available for the requested cash service and, as the result of the verification, provides an amount of money required by the user from a currency cassette, thereby facilitating the cash withdrawal for the user. Therefore, an operator can use an inexpensive telephone network, instead of an exclusive line, thereby reducing operational cost.

Abstract: Apparatus to prevent the theft of coins in the coin return channel of pay phones and coin vending machines. Three vanes are pivotally mounted within or adjacent the return channel to provide a bypass path for returned coins so that blocking of the coin return door or the use of a wire attached to a coin for inserting a wad of material will not prevent retrieval by a user of the telephone or vending machine.
