Abstract: A lighting device utilizes physical or virtual separation of elements within the lighting device to isolate a first portion of data for delivery to a first data network from a second portion of data for delivery to a second data network. The first portion of data relates to a first signal generated responsive to a first sensed condition. The second portion of data may relate to the first signal or to a second signal generated responsive to the first sensed condition or a second sensed condition. The lighting device utilizes a first communication interface to deliver the first portion of data to the first data network and a second communication interface to deliver the second portion of data to the second data network.

Upon detecting an enabling event, the systems and methods include re-enabling one or more of the disabled indicators.

Abstract: A radar/laser emission detector is augmented with a cellular communications capability to provide the capability to share emission detection information amongst drivers to give other drivers even more advanced warning. A network of a plurality of cellular augmented radar/laser emission detector devices may be formed, each having the capability to source the location of radar or laser emission detections to others requesting access to such information, and each being warned when within a proximity of a recent radar or laser emission detection reported by at least one of the plurality of hybrid radar/laser detector devices. A local area, mobile area wireless network (MAWN) is formed in a cellular network to share radar/laser detection information among drivers. Mobile Position Centers (MPCs) are provided in ANSI-41 networks and Gateway Mobile Location Centres (GMLCs) (GSM networks), to determine other members that are proximate to a device that is detecting radar emission.

Abstract: A method, apparatus and program storage device for providing protrusion feedback for a read/write element is disclosed. A slider with a heating element is provided to control the level of read/write element protrusion. A level of heating applied to the slider to change the head protrusion is measured and recorded until acceptable operation of the read/write element is obtained. These measurements are then used to ensure that the read/write element continues to operate properly at different drive temperatures.

Abstract: An apparatus for performing contact printing of a magnetic transition pattern in a magnetic recording medium, comprising: (a) a stamper/imprinter including a body formed of at least one magnetic material having a high saturation magnetization Bsat and a high permeability, including an imprinting surface adapted to be placed in intimate contact with a surface of a magnetic layer, the imprinting surface comprised of a plurality of patterned areas which separate a plurality of areas which are not patterned, each of the areas which is not patterned being provided with at least one of: (i) mechanical reinforcing means for preventing deformation of the body when the imprinting surface is urged into contact with the surface of the magnetic layer; and (ii) gas venting means for facilitating removal of air or other gas from between the imprinting surface and the surface of the magnetic layer when the former is urged into contact with the latter.

Abstract: Disk drive preconditioning allows the head-disk interface to be burnished or worn so that head-disk interference is reduced or eliminated before servo track writing. The head is positioned closer to the disk than the normal fly height during a preconditioning sweep and then returns to the normal fly height during servo track writing.

Abstract: A disc drive data storage system is disclosed that includes a disc storage medium having a disc surface. The system also includes an armature and a slider coupled to the armature. The slider supports a transducer head that communicates with the disc storage medium. The slider flies above the disc surface and positions the transducer head proximate the disc surface. Data representing a topography map of the disc surface is stored in a memory. A controller controls the fly height of the slider above the disc surface as a function of the topography map of the disc surface.

Abstract: An information recording apparatus has a write canceling circuit that monitors interface signals fed from a host and that, when the interface signals are recognized to be abnormal, inhibits write operation against a recording medium either for a predetermined period or until a predetermined condition is fulfilled. This circuit configuration helps eliminate or reduce the occurrence of erroneous write operation as occurs when the received interface signals are abnormal.

Abstract: A disk drive is disclosed for optimizing write current settings relative to drive operating characteristics and a plurality of ambient temperature readings. Test data is written to and read from the disk to generate quality metrics that are evaluated to generate an optimized write current setting for each ambient temperature reading. In one embodiment, the optimized write current settings are derived during manufacturing and used in-the-field during normal operation. In another embodiment, the optimized write current settings are re-optimized in-the-field to compensate for changes in the drive operating characteristics that occur over time (e.g., environmental changes and electrical and mechanical changes).

Abstract: A method and apparatus is provided for measuring a media thermal decay rate for a disk in a disk drive. In one embodiment, reference patterns are written in a plurality of reference sectors on a test track of a disk surface. A thermal decay measurement duration is predetermined. After at least two decades of time longer than the predetermined thermal decay measurement duration have passed since writing the reference patterns in the plurality of reference sectors, sector-under-test patterns are written in a plurality of sectors-under-test, wherein the sectors-under-test and the reference sectors are written in data sectors and alternate with one another about at least a portion of the test track. The mean square error is measured and averaged for the reference sectors, and the mean square error is measured and averaged for the sectors under test.

Abstract: A system and method provide overshoot protection to facilitate driving a load by output circuitry in response to a transition from a first operating mode to a second operating mode. The overshoot protection occurs by masking an input bias from biasing the output circuitry for an initial part of the second operating mode based on a transition to the second operating mode, and then allowing the input bias to bias the output circuitry in a desired manner in a subsequent part of the second operating mode.
