Title: Direct digital airborne panoramic camera system and method
Inventor: SPEASL JERRY A
IPC: H04N5/232
Filed: 1996-05-13
Abstract: The present invention relates to an im-proved airborne, direct digital panoramic camera system and method in which an in-line electro-optical sensor (80) operating in conjunction with a data handling unit (82), a controller unit (84), and real time archive unit (86), eliminates the need for photographic film and film transport appara-tus normally associated with prior art airborne reconnaissance cameras and yet still retains the very high image resolution quality which is so im-portant in intelligence operations and commercial geographic information systems (GIS), mapping and other remote sensing applications. Precise geographic data for the system is provided by the use of navigation aids which include the Global Positioning Satellite (GPS) System (14) and an airborne platform carried GPS receiver (85). The present invention provides a simpler, more effi-cient and less costly panoramic camera by utiliz-ing a simpler and less expensive line-focus type of lens in conjunction with an electro-optical line array sensor.

Abstract: Disclosed are two processes. The first process involves treating a red blood cell-containing composition to inactivate an extracellular or intracellular virus which may be present in said red blood cell-containing composition by subjecting said red blood cell-containing composition to a virucidally effective amount of a phthalocyanine and red light, wherein the improvement involves: (i) determining the action spectrum of said phthalocyanine for causing inactivation of said virus; (ii) determining the action spectrum of said phthalocyanine for causing red blood cell damage; (iii) comparing (i) and (ii), and, if (i) and (ii) are not identical, then determining the wavelength at which the largest favorable difference exists between (i) and (ii); (iv) providing a red light source emitting red light only in 10 nm in either direction of the wavelength determined in (iii); and then (v) subjecting said red blood cell-containing composition to said virucidally effective amount of said phthalocyanine and said provided red light source. In a preferred embodiment, the phthalocyanine is Pc 4, which has the formula:  HOSiPcOSi(CH3)2(CH2)3N(CH3)2. The second process involves transfusing red blood cells to a patient in need thereof by withdrawing red blood cells from a donor, subjecting the red blood cells to the first process and transfusing the red blood cells to said patient.

Title: Procedure and system for the setting up of calls
Inventor: LEPP NEN OSMO
IPC: H04M15/12
Filed: 1996-12-17
Abstract: The object of the present invention is to achieve in the telephone network a new type of procedure and system for call control and to meet a need observed recently in the telecommunication business for calls rated below normal tariffs especially between certain predeterminable subscriptions. The system of the invention does not require any substantial system changes in the telephone network. In addition, calls between predetermined subscriptions can now be rated according to a special tariff and the changes can be easily and flexibly included in the normal invoicing. When the number of subscriptions per customer is limited to two, the common call number for all customers is the same, e.g. 020100. When this number is dialled, the call is directed to the wired network subscription specified in the subscriber number pair, which is stored in a database, when the call is made from a mobile station, and vice versa. When the number of subscriptions connected to the system by a customer is greater than two the common call number comprises a prefix part which is the same for all customers and on the basis of which the telephone network exchange recognizes the service call of intelligent network calls and specially rated calls, and a suffix part which is an integer and which, via the intelligent network, determines the desired individual subscription among the subscriptions selected to be included in the system by the customer.
