20090003188 | PROBE FOR SCANNING OVER A SUBSTRATE AND DATA STORAGE DEVICE - A data storage device comprises a storage medium for storing data in the form of marks and at least one probe for scanning the storage medium. The storage medium may be comprised in a substrate. The probe comprises a cantilever that comprises terminals serving as electrical contacts an being during operation of the probe mechanically fixed to a probe-holding structure, which may be a common frame of the data storage device. A probe further comprises a supporting structure, to which the terminals are mechanically directly coupled or coupled via hinges and which extends away from the terminals. A tip with a nanoscale apex is provided. A beam structure comprises a heating resistor and is attached at ends to the supporting structure. The beam structure is thinned at least in a direction parallel to an axis of the tip compared to an area of the supporting structure abutting the beam structure. | 01-01-2009 |

20080225676 | Data storage device and control - The present invention provides data storage devices, systems and methods. An example device includes: a storage medium for storing data in the form of marks; and at least one probe. The probe(s) and storage medium are operable to move relative to each other, with each probe comprising a tip facing the storage medium and having a force creating unit associated thereto. The force creating units are operable to create a force acting between the tip and said storage medium. The data storage device is operable to erase an indentation mark in the storage medium by way of controlling the force creating unit for creating at least one erase force pulse with a force rise time being less than or equal to the order of 1 microsecond. | 09-18-2008 |

20140320993 | TAPE HEAD WITH THERMAL TAPE-HEAD DISTANCE SENSOR - Tape head with thermal tape-head distance sensor to reduce the distance between the tape and the head to allow an increase in areal density. A tape head designed for reading and/or writing to a tape, including: a tape bearing surface shaped to form an air bearing when moving the tape with respect to the tape bearing surface; a thermal tape-head distance sensor circuit adapted to sense heat dissipated at the level of the tape bearing surface by the tape and thereby sense a distance between the tape bearing surface and the tape; and tape-head distance control means connected to the thermal tape-head distance sensor circuit to receive a signal provided by the tape-head distance sensor circuit and configured to alter the distance according to a signal received from the tape-head distance sensor circuit. This invention is further directed to a method of tape-head distance control for the above tape head. | 10-30-2014 |

20100278938 | GENETIC TEST AND PET DIET - The present invention provides a method of determining the susceptibility of a dog to liver copper accumulation comprising detecting the presence or absence of (a) a polymorphism in the GOLGA5, ATP7a or UBL5 gene of the dog that is indicative of susceptibility to copper accumulation and/or (b) a polymorphism in linkage disequilibrium with a said polymorphism (a), and thereby determining the susceptibility of the dog to liver copper accumulation. The invention also provides a foodstuff comprising copper at a concentration of less than 21 mg/kg dry matter for use in preventing a disease attributable to liver copper accumulation in a dog having genetic inheritance of the Labrador Retriever breed. | 11-04-2010 |
20140351962 | GENETIC TEST FOR LIVER COPPER ACCUMULATION IN DOGS - The present invention provides a method of testing a dog to determine the susceptibility of the dog to liver copper accumulation, comprising detecting in a sample the presence or absence in the genome of the dog of one or more polymorphisms selected from: (a) Chr22_3167534 (SEQ ID NO: 144), Chr22_3135144 (SEQ ID NO: 145), Chr20_55461150 (SEQ ID NO: 146), ChrX_120879711 (SEQ ID NO: 147), Chr19_6078084 (SEQ ID NO: 148), Chr15_62625262 (SEQ ID NO: 149), Chr14_39437543 (SEQ ID NO: 150), Chr15_62625024 (SEQ ID NO: 151), Chr3_86838677 (SEQ ID NO: 152), Chr24_4011833 (SEQ ID NO: 153), Chr18_60812198 (SEQ ID NO: 154), Chr10_65209946 (SEQ ID NO: 155), and the CGCCCC repeat at chromosome location 22:3135287; (b) one or more polymorphisms in linkage disequilibrium with a said polymorphism (a); and/or (c) Chr32_38904515 (SEQ ID NO: 156), Chr8_4892743 (SEQ ID NO: 157) and Chr8_4880518 (SEQ ID NO: 158). | 11-27-2014 |
