Abstract: A vertical cavity surface emitting laser (VCSEL) (100) has a substrate (104), on which are disposed first and second distributed Bragg reflectors (DBRs) (106, 112), each DBR comprising a stack of layers of alternating refractive index, an active layer (108) disposed between the DBRs, and an aperture layer (110) disposed either between the DBRs or within one of the DBRs. The aperture layer (110) has a border (116) having an internal boundary with a plurality of indented portions defining one or more apertures. Such a VCSEL is easily manufacturable and provides a narrow bandwidth output, as well as mitigating at least some of the problems of prior art VCSELs. Mesa (102) may be etched to be non-circular and subsequent selective oxidation of aperture layer (110) results in a non-circular current confinement aperture (114) promoting higher-order lateral modes (LP21).

The stripes have alternating polarity of magnetizations in the along-the-track direction.

Abstract: The present invention provides a method of correction of misspelled, confused words and grammar errors in a text, as well as a computer system employing this method. The method of the invention is user-interactive, which means that, when implemented by a computer system, the interaction between the user and the system is employed with the aid of the user-system interface. In the method of the invention the method detects misspelled and confused words, where some of the detected confused words could be grammar errors, and provides user with the correction alternatives for each such word. In response, the user can chose an appropriate correction, mark the word as correct or require other correction alternatives. The user-system dialog, which is intended to improve the correctness of the text, is repeated until all the words-in-question are corrected or marked by the user as correct.

Abstract: A patterned magnetic recording medium has discrete data islands arranged in spaced-apart tracks, with the tracks being arranged in multi-track groups or “hypertracks”. The islands have an equal island-spacing (IS) distance in the along-the-track direction and within each hypertrack the tracks are spaced-apart an equal track-spacing (TS) distance. If there are N tracks in a hypertrack then the islands in each track of a hypertrack are shifted in the along-the-track direction by 1/N times IS from the islands in adjacent tracks in the same hypertrack. The read and write heads have a lateral or cross-track width generally equal to the cross-track width of a hypertrack, so the read and write heads span all the individual tracks in a hypertrack. The hypertracks are spaced apart cross-track direction by a group-spacing (GS) distance, with GS being greater than TS. The islands in a hypertrack may be shifted in the along-the-track direction by approximately ½N times IS from the islands in adjacent hypertracks.

Abstract: Magnetic disk drive systems and associated methods are described for precisely detecting contact of read/write elements of a recording head with a magnetic disk due to increasing a heating power applied to heating elements in the recording head. Contact is detected based on adjusted timing signals which are generated by measuring the current applied to a spindle motor, and generating an estimated timing signal from the measured motor current for increments of the heating power. An actual servo timing signal is simultaneously measured from servo fields on the magnetic disk, and the adjusted timing signals are calculated based on the difference between the estimated timing signal and the servo timing signal. Multivariate statistical analysis may also be performed on the adjusted timing signals and other contact indicative variables (such as off-track and slider vertical bouncing) to generate a likelihood of contact at the increments of the heating power.

Abstract: Methods, system and apparatus are provided for advertising service offerings in a communication system. An example embodiment comprises at least one device. A first device broadcasts a message of a first type, chooses a value for a time limit and listens for a message sent by a second device. If no message has been received before time limit, elapse, it again broadcasts a message of a first type. Otherwise, the message received from said second device is analyzed and if said message includes valid information about said first device chooses a value for the time limit. However, if said message received does not include valid service description about said first device, a message of a second type is broadcast. This reduces useless broadcast of a complete service list. Broadcast may be initiated more often and, service discovery for new devices coming into proximity takes less time.
