Patent GB-1350891-A (GB)
Title: Electrical power conversion apparatus
IPC: H02M7/537
Filed: 1970-03-13
Abstract: 1350891 Inverting WESTINGHOUSE BRAKE & SIGNAL CO Ltd 19 April 1971 [13 March 1970] 12326/70 Heading H2F A transistor inverter is controlled by an alternating waveform so that in the period between the output current zero crossing and the output voltage zero crossing, the load is isolated from the power source and a conducting path through the load is provided. The inverter may use push-pull transistors with a centre-tapped transformer or centre-tapped source, or, as shown in Fig. 1, it may use a bridge of four transistors VT1, VT2, VT3 and VT4. Transistors VT1 and VT3 operate as a class B push-pull amplifier and VT2 and VT4 operate as switches. Initially a current path through the load is provided by VT1 and VT4, VT4 being saturated. When the sinusoidal control input voltage drops to zero transistor VT1 becomes non-conducting and interrupts the current path between the source and the load. VT4 however does not switch off until the current through the load drops to zero but maintains the sine wave through the load via diode MR1 and transistor VT4. In Fig. 5 blocks X and Y represent the two halves of the bridge, the load current being monitored by a current transformer T2 which turns on transistors VT13, VT16 so as to short-circuit the control waveform applied to VT14 and VT15 at appropriate periods. In Fig. 4 (not shown), VT1 and VT3 are driven by respective emitter followers while VT2 and VT4 are driven by respective common emitter transistors. A higher voltage D.C. supply is provided for the driver transistors.

Title: Generalized user identification and authentication system
IPC: G06F21/31
Filed: 1998-05-12
Abstract: The invention features a method for providing a user access to a secure application. The invention stores in an encrypted form the authentication information necessary to satisfy the authentication requirements of the secure application. When the user requests access to the secure application, the user is presented at his or her display with a request for authentication. The user must manipulate at least a portion of the symbol to respond properly to the authentication request. The user's manipulation(s) of the symbol(s) generate a CodeKey used to decrypt the encrypted stored authentication information into a result. After the result is created, it is provided to the secure application. If the result support's the secure application's authentication requirements (i.e., if the CodeKey has properly decrypted the encrypted stored authentication information), the user will be granted access to the secure application. The invention therefore provides a simple, secure and effective method for a user to gain access to a multitude of secure applications without having to recall a series of complicated passwords.
