Abstract: A secure microprocessor is provided with reduced vulnerability to attack. In the past, the secure operation of such processors has been overcome by observing the behavior of the clock used by the processor. Such observations, and the prediction of subsequent clock pulses therefrom, are prevented by modulating the clock by a substantially random function to provide an unpredictable stream of clock pulses. The secure processor is responsive to the unpredictable stream of clock pulses for processing data in accordance with a security algorithm.

Abstract: Apparatus and methods for specifying contexts for machine-executable instructions. Modern graphical user interface systems employ the callback programming style. In this style, a system event handler responds to an event by executing application-level callback code and providing event information concerning the event as part of the context of the execution. The technique disclosed herein uses callback information names to specify the relationship between the event information and the execution context. The callback information names are defined globally, but represent the event information for a single execution of the callback code. Using the callback information names, it is possible to define the callback code in the function which adds the callback code to the graphical user interface system.

Abstract: An electrical connector assembly has a pair of mating connector housings carrying mating metal terminals, a double ended shorting clip carried by one of the housings and having both ends thereof in spring biased engagement with its associated metal terminals in that housing, a third housing encircling the housings and a tethered connector position assurance member connected to the third housing. The shorting clip first has one end automatically disengaged from its associated metal terminals by a first cam when the connector housings are mated together and then its other end automatically disengaged from its associated terminals by a second cam on the connector position assurance member when it is connected to the third housing so that a shorting path across the associated metal terminals is only fully disconnected if proper mating of the connector housings is assured. The third housing provides environmental splash protection, strain relief for conductors connected to the terminals and has an integral terminal position assurance means for assuring proper positioning of the terminals in the housing. The third housing also has a depressible dome to release the connector housings from each other.

Abstract: An animal cell is co-transfected with both a recombinant DNA viral vector which bears a promoter, a recombinase gene and a poly(A) sequence and a recombinant DNA viral vector which bears two recombinase-recognition sequences and which further bears an origin of replication, a promoter a foreign gene and a poly(A) sequence, each of which is located between the two recombinase-recognition sequences. Thereafter, in the co-transfected animal cell, a DNA fragment containing the origin of replication, promoter, foreign gene and poly(A) sequence is excised from a vector by the action of recombinase expressed by the other vector. The excised DNA fragment forms a circular DNA molecule which autonomously replicates in the co-transfected animal cell due to the origin of replication, whereby the foreign gene is continuously expressed. 
     Accordingly, when the foreign gene corresponds to a gene which is defective in a patient, the combination of the above two DNA viral vectors is useful in gene therapy, especially in the treatment of a patient with a hereditary disease.

Abstract: A tristate buffer circuit for mixed voltage applications. The circuit is built from field effect transistors and is used as an output buffer in applications where a low voltage component needs to drive both components which are powered by the same low voltage and components which are powered by a higher voltage. The circuit uses a floating n-well technique in combination with a pass-gate network, a one-shot circuit, and a process-dependent bias voltage reference. It is particularly useful on CMOS semiconductor chips which have bus interfaces, such as local area network (LAN) protocol chips.

Abstract: An apparatus for detecting an abnormality of an air flow meter (43) is disclosed. The flow meter (43) is disposed in an air intake passage (20) of an engine (10) to detect an actual flow rate of air flowing through the air intake passage (20). The air intake passage (20) has a throttle valve (22) with a variable opening size (TA) to control the actual rate of the air flowing in the air intake passage (20). The throttle valve (22) adjusts the actual flow rate of the air according to an engine speed (NE) when the opening size (TA) is in a first range, and regardless of the engine speed (NE) when the opening size (TA) is in a second range. A throttle sensor (44) detects the opening size (TA) of the throttle valve (22). An ECU (50) computes a target rate of the air flowing in the air intake passage (20) based on the detected opening size (TA) of the throttle valve (22), and a marginal range for allowing a deviation of the actual rate of the air flow from the target rate. The ECU (50) determines the abnormality of the air flow meter (43) when the opening size (TA) of the throttle valve (22) is in the second range and the actual rate of the air is out of the marginal range.
