Abstract: A system protects a computer from suspicious Downloadables. The system comprises a security policy, an interface for receiving a Downloadable, and a comparator, coupled to the interface, for applying the security policy to the Downloadable to determine if the security policy has been violated. The Downloadable may include a Java® applet, an ActiveX®  control, a JavaScript® script, or a Visual Basic® script. The security policy may include a default security policy to be applied regardless of the client to whom the Downloadable is addressed, or a specific security policy to be applied based on the client or the group to which the client belongs. The system uses an ID generator to compute a Downloadables ID  identifying the Downloadable, preferably, by fetching all components of the Downloadable and performing a hashing function on the Downloadable including the fetched components.  Further, the security policy may indicate several tests to perform, including (1) a comparison with known hostile and non-hostile Downloadables; (2) a comparison with Downloadables to be blocked or allowed per administrative override; (3) a comparison of the Downloadable security profile data against access control lists; (4) a comparison of a certificate embodied in the Downloadable against trusted certificates; and (5) a comparison of the URL  from which the Downloadable originated against trusted and untrusted URLs. Based on these tests, a logical engine can determine whether to allow or block the Downloadable.

Patent CA-2285134-A1 (CA)
Title: Method and device for the coherent addition of the emission of semiconductor lasers
Inventor: DULTZ WOLFGANG
IPC: H01S5/40
Filed: 1999-10-05
Abstract: Described is a method and a device for the coherent addition of the emissions of semiconductor lasers, in particular for use in telecommunications. The basic idea on which the present invention is based is to couple the single emitters in such a way that each emitter senses some of the emission of all the others.      Instead of allowing all the emitters to radiate independently, they are arranged in a common resonator (3). Using an optimization method, for example the method of simulated annealings, the shape of the resonator mirror is optimized until such time as it satisfies a pre-described set of mathematically formulated requirements in the sense of a set criterion, and does so in an optimal manner. Essentially, the method is based on the following factors: the single emitters in the form of single diodes, a diode matrix, or diode bars (2) are set up between two or more mirrors (1). At least one of these mirrors (1) has a special non-spherical surface as an internal correction element.      Alternatively, the mirrors 1 can be spherical. In this case, however, at least one non-spherical phase plate must be arranged in the path of the resonator beam. Outside the resonator (3), an additional system comprising a generator and a secondary beam shaper transforms the emitted beam into the desired amplitude/phase distribution and power density (5). The internal correction elements are constructed by a global optimization method, or the internal correction elements and the external generalize lenses are constructed together by means of a global optimization method.

Title: Call center telephone and data flow connection system
Inventor: COOK WENDY S
IPC: H04M3/51
Filed: 2000-01-11
Abstract: A method and system for transferring telephone calls and data between computer programs in a call center. Flow connection modules associated with call center application programs allow data and telephone calls to be transferred from one computer program to another in the call center. The flow connection modules may be combined with a locator program such that the combination replaces the automatic call distributor ("ACD") in a call center. The flow connection modules enable development of modular call centers, allowing call center agent workstations to be easily increased or decreased. In operation, an application notifies its flow connection module that a call on a telephone in the workstation should be transferred to another application. The flow connection module establishes a data connection with a flow connection module associated with the other application. The flow connection module sends call-related data to the other flow connection module which then returns the telephone extension associated with the other application. The flow connection module requests a computer telephony interface ("CTI") link associated with a phone switch to transfer the call to the other application's telephone. The CTI link directs the phone switch to transfer the telephone call from the original application's workstation to the telephone of the other workstation. Having received notification of the transferred call, the other flow connection module informs the original flow connection module that the call has been successfully transferred, and the original flow connection module then disconnects the data connection.
