Patent number: 10061279Abstract: An apparatus, method and computer program product for scheduling on/off control of equipment. The method implements an iterative approach that uses one objective and sets a tolerance value on the other objectives. Initially, the method computes the value of the different objective functions given a current feasible solution.

Patent number: 9625902Abstract: In a control loop, a command signal is applied to physical components to cause movement of the physical components. The position of the physical components is detected and used to generate subsequent command signals. In an implementation, an integrity detection system causes an excitation signal to be injected onto the command signal to cause movement of the physical components at an excitation frequency. This movement is detected in the physical system control loop and isolated by the integrity detection system. If the integrity detection system fails to detect energy in the excitation frequency band, a failure of at least one component of the control system is inferred.Type: GrantFiled: March 31, 2014Date of Patent: April 18, 2017Assignee: Bose CorporationInventor: Lawrence D.

Patent number: 9420006Abstract: A system and method of managing security policies in an information technologies (IT) system are provided. In an example, the method includes receiving an input indicating a high-level security policy for the IT system, the received high-level security policy relating to non-functional system attributes for the IT system and received in a format that is not machine-enforceable at an enforcement entity of the IT system. A functional model for the IT system is determined, where the functional model indicates functional system attributes of the IT system. At least one pre-configured rule template is loaded, and at least one machine-enforceable rule is generated in a manner compliant with the received high-level security policy by iteratively filling the at least one pre-configured rule template with functional system attributes indicated by the functional model. After the generating step, the at least one machine-enforceable rule can be distributed (e.g.Type: GrantFiled: April 27, 2015Date of Patent: August 16, 2016Inventors: Ulrich Lang, Rudolf Schreiner
