20090051568 | METHOD AND APPARATUS FOR TRAFFIC CONTROL USING RADIO FREQUENCY IDENTIFICATION TAGS - A computer implemented method, apparatus, and computer usable program code for controlling traffic. A set of vehicles is monitored moving from one radio frequency identification tag sensor to another radio frequency identification tag sensor in a network of radio frequency identification tag sensors to detect movement of the set of vehicles. A set of traffic patterns is identified in response to detecting the movement of the set of vehicles. A determination is made as to whether a traffic pattern in the set of traffic patterns is a delayed traffic pattern. In response to a determination that the traffic pattern in the set of traffic patterns is the delayed traffic pattern for a traffic control light at an intersection, the timing of the traffic control light is changed to increase traffic flow through the intersection. | 02-26-2009 |
20100031271 | DETECTION OF DUPLICATE MEMORY PAGES ACROSS GUEST OPERATING SYSTEMS ON A SHARED HOST - A hypervisor receives a memory page checksum from a guest operating system, which corresponds to a page of memory utilized by the guest. Next, the hypervisor proceeds through a series of steps to detect that the memory page checksum matches a checksum value included in a checksum entry item, which includes an identifier of a different guest. In turn, the hypervisor shares the page of memory between the guest and the different guest in response to detecting that the memory page checksum matches the checksum value included the checksum entry item. | 02-04-2010 |
20100042996 | UTILIZATION MANAGEMENT - In an illustrative embodiment, a computer implemented method for utilization management is provided. The computer implemented method initiates a utilization monitor to monitor a set of processes, records utilization data for an identified process of the set of processes to form recorded utilization data, and determines whether the recorded utilization data exceeds a utilization threshold. The computer implemented method, responsive to a determination that the recorded utilization data exceeds a utilization threshold, performs an action to manage utilization. | 02-18-2010 |
20100150531 | Method to Improve Storage Efficiency of High Definition Digital Video Recorders - A method and computer program product for improving storage efficiency for a digital video recorder. In one embodiment, a determination is made as to whether television programming is being presented on a high definition channel or a standard definition channel. The television programming is recorded using the digital video recorder responsive to determining that the television programming is being presented on a standard definition channel without making any resolution changes to the television programming. A determination is made as to whether the content of the television programming originates in high definition or standard definition. When the television programming originates in standard definition, a determination is made as to whether a corresponding standard definition channel is available. Responsive to determining the corresponding channel is available, the television programming is recorded in standard definition from the corresponding channel. Otherwise, the television programming is downscaled on the high definition channel to a standard definition resolution. | 06-17-2010 |
20100180158 | Managing Statistical Profile Data - The illustrative embodiments disclose a computer implemented method, apparatus, and computer program product for refining statistical profile data. In one embodiment, the process interrupts an execution of a software program in response to detecting a profiling event during the execution of the software program. The process then records an event sample associated with the profiling event. The event sample is recorded in a log file. The process also inserts a set of markers describing and associated with the event sample into the log file. The process then resumes the execution of the software program. | 07-15-2010 |

20100025209 | METHOD FOR DETECTING A SWITCH POSITION OF AN ISOLATING SWITCH, OR OF A GROUNDING SWITCH - A method is disclosed for detecting the switch position of an isolating switch, or of a grounding switch, wherein a displaceable switching meter is applied to the contact part in the gap of a contact part in the closed switch position, and wherein the displaceable switch meter can be spaced from the contact part in the open switch position. In at least one embodiment, an optical signal is influenced by the switch meter for differentiating the two switch position with a closed switch position. If the optical signal is influenced, it is indicated that the isolating switch, or the grounding switch, is in the closed switch position. Otherwise it is indicated that the isolating switch, or the grounding switch, is in the open switch position. | 02-04-2010 |
20140138200 | NON-RAIL-BOUND VEHICLE - A non-rail-bound vehicle, truck or bus, includes a current collector feeding electrical energy from an overhead line installation having a contact wire. The collector has a contact strip with a working region contacting the contact wire. An actuating device coupled to the collector adjusts the contact strip. The contact strip is horizontal and adjustable transversely to a vehicle longitudinal axis. A sensor senses the position of the vehicle relative to the contact wire. A control device connected to the sensor and the actuating device actuates the actuating device based on the sensed vehicle position, so that the contact strip maintains contact with the contact wire within its working range. The vehicle thus reliably maintains contact with the contact wire through the collector during operation on multilane roadways with an at least partially electrified lane, even at relatively high speeds of, for example, 80 to 100 km/h. | 05-22-2014 |
