Patent number: 8716688Abstract: An electronic device includes a first electrode, a second electrode and a nanowire connected between the first and second electrodes to allow electric current flow. The nanowire is made from a conductive material exhibiting a variable resistance due to electromigration. The nanowire is repeatably switchable between two states. A voltage clamp operates through feedback control to maintain the voltage across the nanowire and prevent thermal runaway.Type: GrantFiled: February 25, 2011Date of Patent: May 6, 2014Assignee: The University of Kentucky Research FoundationInventors: Douglas R. Strachan, Stephen L. Johnson

Patent number: 7774599Abstract: A system securing inter-process communication (IPC) based on trust includes a user quota mechanism to provide resource management of IPC's. A single user is allowed to allocate a fixed amount of objects less than a system maximum. A trusted IPC mechanism mediates access to IPC objects by employing signed executables signed by a key and containing a list of trusted keys. A trust relationship is used among a set of subjects connected to an IPC to determine whether communication can be carried out between processes. In order for the processes to communicate via an IPC, either they have to trust each other, or a kernel must trust one process and that process must also trust the other process.Type: GrantFiled: September 15, 2006Date of Patent: August 10, 2010Assignee: Panasonic CorporationInventors: Jinhong Guo, Stephen L. Johnson, Il-Pyung Park, Lasse Bigum, Henrik Davidsen, Lars T. Mikkelsen, Egon Pedersen, Anders Ravn, Emmanuel Fleury

Patent number: 7698731Abstract: A security architecture is provided for accessing security components associated with an operating system. The security architecture is generally comprised of: a policy tree storing a plurality of security policies, where each security policy is define as at least one system call which correlates to a security operation and a corresponding security component for executing the security operation; and a policy manager adapted to intercept system calls from the operating system and operable to determine an applicable response based on the policy tree. The policy tree and the policy manager reside in a protected memory space of the execution environment.Type: GrantFiled: October 25, 2004Date of Patent: April 13, 2010Assignee: Panasonic CorporationInventors: Stephen L. Johnson, Jinhong Katherine Guo, Il-Pyung Park

Publication number: 20100038658Abstract: A polymeric light-emitting diode (PLED) and methods of making same. In one embodiment, the PLED comprises a substrate, a layer of a first conductive material formed on a surface of the substrate, a layer of a conductive polymeric material deposited on the layer of the first conductive material, a layer of a luminescent polymeric material deposited on the layer of the conductive polymeric material, and a layer of a second conductive material formed on the layer of the luminescent polymeric material, wherein at least one of the layer of the conductive polymeric material and the layer of the luminescent polymeric material is deposited by the laser vapor deposition (LVD).Type: ApplicationFiled: September 7, 2007Publication date: February 18, 2010Applicant: Vanderbilt UniversityInventors: Richard F. Haglund, JR., Stephen L. Johnson, Hee K. Park

Patent number: 7600117Abstract: Access control is mediated by a set of 2-tuple labels or attributes which are associated with subject and object entities, respectively. Subject entitles, such as processes, have separate read and write attributes, while object entities, such as files, have separate integrity and write control attributes. The system implements a set of rules to provide both integrity control and confidentiality protection. Specifically, write operations to an object are inhibited where the subject's write attribute is lower than the write control attribute of the object. Read operations from an object are inhibited where the subject's read attribute is lower than the object's integrity attribute. When a subject reads from an object having a lower integrity level than the subject's read attribute, the subject's read attribute is demoted.Type: GrantFiled: September 29, 2004Date of Patent: October 6, 2009Assignee: Panasonic CorporationInventors: Jinhong Katherine Guo, Stephen L. Johnson, Il-Pyung Park

Publication number: 20080201778Abstract: Selected system calls are monitored to generate frequency data that is input to a probabilistic intrusion detection analyzer which generates a likelihood score indicative of whether the system calls being monitored were produced by a computer system whose security has been compromised. A first Bayesian network is trained on data from a compromised system and a second Bayesian network is trained on data from a normal system. The probabilistic intrusion detection analyzer considers likelihood data from both Bayesian networks to generate the intrusion detection measure.Type: ApplicationFiled: February 21, 2007Publication date: August 21, 2008Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Jinhong Guo, Stephen L.

Publication number: 20070300300Abstract: An intrusion detection system includes a computer readable datastore containing a double Markov model for modeling events in system log files of a computer system by looking at multiple log files and correlations among different log files. An intrusion detection module performs intrusion detection by using the double Markov model to assess probability that a new event is an intrusion, including routinely scanning the system logging data and processing the data periodically. A countermeasures module takes countermeasures when an intrusion is detected.Type: ApplicationFiled: June 27, 2006Publication date: December 27, 2007Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Jinhong K.

Patent number: 7243235Abstract: A mandatory access control method for securing an operating system is presented. A first integrity subject reads a first object. The first integrity subject attempts to read a second object. It is determined that a conflict exists between the first and second objects. At least one security rule is applied to the conflict between the first and the second objects.Type: GrantFiled: June 8, 2004Date of Patent: July 10, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Jinhong Katherine Guo, Stephen L.

Patent number: 6122918Abstract: A storage cabinet suitable for storing cigars, wherein relative humidity and temperature levels in the cabinet are maintained within a programmed range. More specifically, an ideal relative humidity to temperature ratio is maintained within the cabinet. An indicator displays real-time temperature, relative humidity and/or moisture level of the interior of the cabinet. A temperature control system comprises thermoelectric chips, rather than compressors, to maintain the temperature inside the cabinet. A humidity control system comprises a water container and fans directed at the water container for distributing humidity throughout the cabinet.In an alternate embodiment, a moisture level is programmed and maintained despite fluctuations in temperature and/or humidity within the cabinet.Type: GrantFiled: July 9, 1999Date of Patent: September 26, 2000Assignee: Odin Design LimitedInventor: Stephen L. Johnson, Jr.

Patent number: 4536823Abstract: An improved panel board construction is described, including an extruded insulative base pan which slidably engages at least one main-line bus bar and a neutral connector element and which has a plurality of electrical contact points. The base pan also prevents current flow through the base pan between any two of the contact points of the main-line bus bars. A protrusion extending from the base pan having a tortuously formed surface thereon prevents current flow through the base pan. The panel board is provided with interchangeable main-line lugs which may be used to directly contact the main-line bus bars or, alternatively, support a main-line circuit breaker between the lugs and the main-line bus bars. The base pan is symmetrically formed by an extrusion process so that it may be adaptable for use with a variety of panel board sizes simply by shearing the base pan to form the appropriate length.Type: GrantFiled: October 27, 1981Date of Patent: August 20, 1985Assignee: Siemens-Allis, Inc.Inventors: Wayne A. Ingram, Stephen L. Johnson, Thomas E. Coleman
