Abstract: Compromise of a predetermined secure data processing routine (14, 49) by a procedure known as a "clock attack" is prevented by a method that inhibits synchronization with externally generated instructions by preventing determination of the time of execution of the predetermined data processing routine in relation to occurrence of an observable external event that precedes the execution of the predetermined routine. The method includes the step of (a) randomly varying the duration between the occurrence of the observable external event and the execution of the predetermined routine. Step (a) includes the steps of (b) executing one or more interim data processing routines (20, 21, 22, 52) between the occurrence of the observable external event and the execution of the predetermined routine; and (c) randomly varying the duration of said interim routines. Steps (b) and (c) may include the step of (d) randomly assembling m said interim routines for said execution from a group (52) of n stored routines having different durations, wherein m and n are integers, with n being greater than m. Step (d) may include either the step of (e) randomly accessing said m interim routines from a secure memory (51); or the steps of (f) randomly accessing pointers (58) for said m interim routines from a secure memory (60); and (g) accessing said m interim routines from a memory (51) in response to said pointers. Step (c) includes the step of (h) randomly varying the duration of the interim routines in response to dynamically processed data that does not repetitively recur each time said interim routines are accessed. The method further includes the steps of (i) monitoring (26) said interim routines to detect whether said interim routines are being tampered with; and (j) preventing (38) the execution of said predetermined routine in response to detecting that said interim routines are being tampered with. <IMAGE>

Abstract: The invention concerns an in vitro method that is particularly useful for the diagnosis of thromboembolic diseases, such as hereditary or non-heriditary thrombophilia, and to determine the risk for trombosis in connection with pregnancy, taking anti-conception pills, surgery etc. The method is characterized in that the coagulation system in a sample is activated wholly or partly in a manner known per se and incubated with activated Protein C, whereupon a substrate conversion reaction rate like clotting or conversion of a chromogenic substrate is determined. The conversion rate obtained is compared with values obtained for normal plasma samples. If the rate is enhanced, it indicates that the individual from which the sample is derived may suffer from a thromboembolic disease.

Abstract: The apparatus comprises a filling nozzle having a conical part so that it can fit in a leaktight manner on to a burred aperture in a tooth to be filled. The nozzle has a suction tube and a first annular channel connected to the suction tube and coming out into the dental cavity in order to create a vacuum therein. A second central channel serves to bring a filling paste from a reservoir to the dental cavity. The cross-section of flow of the first channel is several times smaller than that of the second channel, so that the paste travels much more slowly in the first channel than in the second, under the effect of the partial vacuum in the dental cavity.

Abstract: A method of manufacturing a dynamic groove bearing (45, 71, 111) with an external bearing part (17, 61, 91) and an internal bearing part (47, 67, 113) which are rotatable relative to one another and which have cooperating bearing surfaces (39, 53), (63, 69), (103, 121) with groove patterns (41, 65, 105). According to the invention, the bearing surface (39, 63, 103) of one of the bearing parts (17, 61, 91) is formed and simultaneously provided with the groove pattern (41, 65, 105) through plastic deformation of a ductile material (36, 100) by means of a press tool (37, 101) and a die (1, 55, 73) with a die pattern (13, 59, 83) which corresponds to the groove pattern (41, 65, 105). The ductile material (36, 100) is, for example, a tin alloy such as white metal or Babbitt's metal. The die (1, 55, 73) can be repeatedly used so that large numbers of dynamic groove bearings (45, 71, 111) according to the invention can be manufactured in a comparatively simple manner. The method is used in the manufacture of a rotatable scanning unit (123) for reading or writing a magnetic tape (125) in a magnetic tape device (157). The method is also used for the manufacture of a dynamic groove bearing (233, 235) by means of which a rotatable information disc (213) is supported in a compact, cassette-shaped data storage unit (209). <IMAGE>

Abstract: A clock synchronization system for synchronizing the performance of a number of clocks (46) so that they run parallel with a reference clock is disclosed. Each clock of this synchronization system includes a counter (52) that indicates the current time and that is sequentially incremented by a counter advance signal applied thereto. A time counter controller (54) both initializes the counter and generates the clocking signal that controls the advancement of the counter. The time counter controller further monitors the time indicated by the counter and compares it to a reference-time signal received from a reference clock. Based on the comparison, the time counter controller selectively reinitializes the counter and adjusts the rate at which the clocking signal is applied to the counter so as to ensure that the counter advances at a rate equal to the rate at which the reference clock advances. In some versions of the invention, the comparison of the reference-time signal to the actual clock counter time is made at a maintenance operation point (58) remote from the clock. In these versions of the invention, the maintenance operation point reports the difference in the two times back to the time counter controller, which, in turn, makes the appropriate adjustments to the counter and to the clocking signal. <IMAGE>

Abstract: In a cellular radio system the facility is provided for a call to be broadcast from a control centre (Mx), (for example an emergency service controller), or from any of the mobile units (Ma), (Mb), (Mc) etc., to all of the others. Each cell allocates a single channel to the broadcast service, irrespective of the number of mobile units in the cell. This allows more efficient use of the available channels than the use of a separate channel for each mobile unit. In one embodiment no channel is allocated to a cell unless at least one mobile unit responds to a paging signal in that cell. Paging may continue throughout a broadcast call to allow a channel to be allocated when a mobile unit enters a previously unoccupied cell or to allow release of a channel should all mobiles leave a previously occupied cell. The broadcast facility can be provided on a cellular network which also supports other mobile units which do not receive the broadcast service, and whose operation is not affected by it.
