Abstract: In one embodiment, values are retrieved from a number of MISRs which are coupled to a number of microprocessor buses, and a random number is generated based on the retrieved values. In another embodiment, a built-in self-test (BIST) local block of a microprocessor is assigned a major address, and each of a number of multiple input shift registers (MISRs) in the BIST local block is assigned a minor address. An instruction to turn on and initialize the MISRs is then issued, and a request to read the MISRs is issued in response to a request for an encryption key. The MISR readings are then XORed with each other, and with historical readings, if any, to generate an encryption key.

Abstract: Upon input of a password to a computer, the password is subjected to a hashing function to generate an N-bit number. The N-bit number is used as an index to retrieve at least one object from a list of objects. The retrieved objects are presented to a user, and the user is prompted to verify that the objects are recognizable as the objects which the user knows to be associated with their password. If the objects are verified as being recognizable, the password is accepted as a correct and intended input. Alternative embodiments of this method, and associated apparatus, are also disclosed.

Abstract: The present invention includes a method for testing a chip, comprising the steps of measuring power drawn by the chip, calculating a test frequency using the measured power drawn by the chip, and determining performance of the chip at the calculated test frequency. The present invention also includes a system for testing a chip including a first sensor to measure power drawn by the chip, a controller to calculate a test frequency using the measured power drawn by the chip, and a second sensor to measure speed of the chip at the calculated test frequency.

Abstract: Upon input of a password to a computer, the password is subjected to a hashing function to generate an N-bit number. The N-bit number is divided into two smaller numbers that are used as indexes to retrieve objects from a list of objects. The retrieved objects are presented to a user, and the user is prompted to verify that the objects are recognizable as the objects which the user knows to be associated with their password. If the objects are verified as being recognizable, the password is accepted as a correct and intended input. Alternative embodiments of this method, and associated apparatus, are also disclosed.

Abstract: A random number is generated by periodically issuing an operating system call to retrieve values from a number of multiple input shift registers (MISRs) which are coupled to a number of microprocessor buses. The number of MISR readings are then stored in a temporary location, or a number of values based on the MISR readings are stored in a temporary location. A random number is then generated from the stored MISR readings or stored values.

Abstract: A multilayer foil insulation, and related method of manufacturing the insulation, that is used for dissipating heat and attenuating sound. Layers of foil are stacked in a spaced apart relationship, and include perforated layers and an imperforate layer adjacent to or sandwiched between the perforated layers. Each of the perforated layers includes a pattern of perforations that define a plurality of standoffs that extend from the perforated layers and that contact an adjacent layer, thereby defining insulating spaces therebetween and maintaining the spaced apart relationship. The perforations permit sound to enter the multilayer foil insulation, wherein sound is acoustically scattered as it passes into the multilayer foil insulation through the perforations and the imperforate layer acoustically absorbs the sound within the multilayer foil insulation.

Abstract: The present invention relates to a method for making a shielded automobile component and the shielded automobile component itself. The component includes a composite formed of a metal sheet which includes protrusions which extend from a surface of the metal sheet and a blow-molded thermoplastic layer formed around the protrusions which fixes the blow-molded layer to the metal sheet during the molding process. The protrusions on the metal sheet define plain polygonal areas which are free of protrusions.

Abstract: An intergrated circuit package with plastic or glass reinforcement of leads to increase lead rigidity, to improve lead alignment and positional stability, and to prevent bent leads. The invention is particularly applicable to surface mount packages. For plastic packages, plastic between the leads is formed during molding of the plastic package. For metal packages, the plastic is molded as a separate operation. For ceramic packages with lead frames, glass may be formed as a separate operation or may be formed at the same time as a glass seal for the ceramic package. Reinforcement can optionally be thicker than the leads for increased rigidity. Optional extended lead lengths enable plastic or glass to be formed on either side of the soldered foot area of each lead. No changes to test fixtures or to pick and place equipment are required.

Abstract: An improved supporting and spacing member for packaging a multi-layer stack of rolls of material. The supporting and spacing member includes an elongated bar of expanded foam material with a stabilizing member located within a semi-cylindrical indentation to provide a pair of indentation portions to retain opposing roll ends for added flexural stiffness and better stability for the stack.
