Abstract: A rotary wing aircraft includes a single main rotor hub configured to receive a rotor blade. The rotor blade includes a blade root, a blade tip, and a blade body. The blade body includes a leading edge and a trailing edge and defines a feathering axis. The leading edge and the trailing edge each include a first portion and a second portion that extend toward a first direction and a second portion, respectively. At a given radial location along the feathering axis, a local twist angle changes from a positive value to a negative value, a chord length decreases in value, a distance between the trailing edge and the feathering axis decreases in value, and the first portion of the leading edge extends toward the first direction. The rotor blade assembly also includes a trailing edge assembly having a trailing edge flap configured to be selectively deployed by an actuator.

Abstract: A system, method, and apparatus for melting snow. The snow melting system may include a container having a cavity that is at least partially filled with a liquid. There should be a sufficient amount of liquid in the container to submerge a heating section of a heating assembly that is located within the cavity. The heating assembly is operably coupled to a source of steam, such as the steam generated from a boiler or steam generator in an existing building. The heating assembly may also include a condensate recovery section that is configured to flow condensate from the steam back into the liquid in the cavity of the container. The snow melting system also includes a spray assembly that pumps the heated liquid to a plurality of sprayers that then spray the heated liquid back down onto snow placed within the cavity of the container.

Abstract: A system for racking billiard balls of a given diameter on a playing surface, the system comprises a billiard ball gauge, a pro-rack and recreational-rack. The pro-rack and the recreational-rack each include a frame having an interior opening with an internal periphery. The internal periphery has segmented circular portions. Each rack is a top racking rack used to position and hold billiard balls in close contact when the rack rests upon the top of the balls. The billiard ball gauge determines which rack is best for the given size of the balls.

Abstract: A base layer for a suspension. The base layer includes a structure. The structure has a slider end portion and a tail portion. The structure includes an opening in the tail portion. The opening provides access to a conductive assembly coupleable there with. The structure also includes a strengthening member integrated within said opening.

Abstract: A method and apparatus for improving the capacity of a hard disk drive is provided. In one embodiment, a portion of timing information is written to a first disk prior to coupling the first disk with a hard disk drive. The first disk is then coupled with the hard disk drive having a read element aligned with a write element on a head portion of a head gimbal assembly. The timing information is then provided to the read element during a writing of a set of servo track information on the disk, wherein the portion of timing information allows the read element to be aligned with the write element on the head during the writing of the set of servo track information.

Abstract: A disk drive that includes nonvolatile memory monitors the drive's reliability-related parameters to detect real or potential failure events, and records failure-related data in nonvolatile memory, rather than in reserved areas of the disks. The monitoring may be by running a diagnostic routine or by regular or periodic monitoring of disk drive sensors, like temperature and shock sensors. The failure events to be monitored and recorded may include defective data sectors. When a new defective sector is detected after the disk drive has been put into operation, that defective sector is taken out of service and its logical block address (LBA) is mapped to a memory space in the nonvolatile memory rather to a reserved spare sector on the disk.

Abstract: Techniques are provided for detecting and correcting polarity reversals in signals generated by read/write heads that are used to read magnetic data. Directional patterns are stored in regions of each data track. The directional patterns are used to indicate whether the read/write head has reversed polarity. The read sensor reads the directional patterns along with other data stored on the disk. Electronic circuitry decodes the directional patterns to determine if the read/write head has reversed polarity. If the circuitry determines that the polarity of the read/write head has reversed, the circuitry reverses the polarity of output signals generated by the read sensor to correct for the polarity reversal of the head.

Abstract: The performance capability of different heads that are part of the same hard disk drive (HDD) are utilized by an adaptive format that includes a plurality of storage zones and at least one reset zone that are distributed along a radius of the hard disk such that a reset zone is disposed between two adjacent storage zones. Each storage zone has a plurality of associated data tracks and each reset zone includes a plurality of data tracks. The number of data tracks associated with each respective storage zone is based on a performance capability of a head associated with the hard disk and includes at least one data track of at least one reset zone adjacent to the storage zone when the number of data tracks associated with the storage zone exceeds the number of data tracks that are between each reset zone adjacent to the storage zone.

Abstract: Format efficiency of a hard disk of a hard disk drive having a rotary actuator and a read/write head having a read element that is offset from a write element is improved by writing a data track having a length that is based on an arc of the rotary actuator, the radial position of the read/write head with respect to the hard disk and the offset between the read element and the write element.

Abstract: A unitary structure for supporting a hose nozzle has an angled support surface formed between two generally vertical walls. The walls are attached to the ends of two legs at an angle of approximately 30.degree. so that the legs intersect the ground at an angle of approximately 60.degree. for stability.

Abstract: A continuous vent in the form of a resilient apertured trough which fits into a bevel in the center of the soffit or at the fascia or the wall. The advantages of the vent is that its hold is based on its shape, its resilience and the angle of the bevel in the soffit. The vent is used in existing soffits or on new construction. The method involves the steps of venting a soffit by cutting two beveled ends a few inches apart and inserting a resilient apertured vent in the space between the bevels. For new construction, one beveled strip is temporarily adhered via an adhesive to hold the vent in place until the second bevel is completed and both beveled pieces are installed.
