US Classification:

299 14, 299 105, 299 95, 175 57, 175 19

Abstract:

Apparatus and methods of using lasers are provided for spalling and drilling holes into rocks. A rock removal process is provided that utilizes a combination of laser-induced thermal stress and laser induced superheated steam explosions just below the surface of the laser/rock interaction to spall the rock into small fragments that can then be easily removed by a purging flow. Single laser beams of given irradiance spall rock and create holes having diameter and depth approximately equal to the beam spot size. A group of the single laser beams are steered in a controllable manner by an electro-optic laser beam switch to locations on the surface of the rock, creating multiple overlapping spalled holes thereby removing a layer of rock of a desired diameter. Drilling of a deep hole is achieved by spalling consecutive layers with an intermittent feed motion of the laser head perpendicular to the rock surface.

H04W 24/00

US Classification:

4554563

Abstract:

The claimed subject matter provides systems and/or methods that stream pertinent and/or selected content to a mobile device based at least in part on the location of the mobile device. The system can include components that detect the presence of a mobile device within a coverage area dynamically demarcated by an access point, determine the mobile device location in relation to the access point, and thereafter supplies event information to the mobile device based on the mobile device location in relation to the access point.

Assignee:

Quantum Corporation - Milpitas CA

International Classification:

G11B 545
G11B 2120

US Classification:

360106

Abstract:

An improved actuator apparatus is employed in a hard disk drive device for positioning read/write heads over tracks on a data storage disk of the disk drive. The actuator apparatus includes an all plastic C-block assembly providing the actuator apparatus with a reduced weight, lower inertia and better damping characteristic which enable improved dynamic performance. The C-block assembly includes a body portion and a pair of tapered support arms extending from the body portion in a parallel orientation. The support arms each have a suspension for a read/write head staked thereto within a mounting surface aperture at a distal end of the arm. The mounting surface aperture is configured to have a non-circular shape to facilitate staking of the read/write head to the support arm and enable construction of the C-block assembly out of plastic. The non-circular shape of the mounting surface aperture additionally enables swaging within the aperture of the plastic support without causing the plastic support arm to break or crack.

Assignee:

Quantum Corporation - Milpitas CA

International Classification:

G11B 554

US Classification:

360105

Abstract:

An aerodynamically powered release latch mechanism is provided for a fixed disk drive. A disk clamp for clamping a single data storage disk to a spindle hub comprises a centrifugal airflow pumping structure, such as radially and axially extending, generally L-shaped turboblades, for increasing the level of a vane deflecting airflow as the disk rotates. The vane deflecting airflow releases an aerodynamically released actuator latch mechanism.

Inventors:

Thomas R. Stone - San Francisco CA

Assignee:

Quantum Corporation - Milpitas CA

International Classification:

G11B 554

US Classification:

360105

Abstract:

An airlock latch assembly for restraining a disk drive actuator when the disk is not spinning and the disk drive is subjected to a rotational shock force includes a latch member meshably engaged with a counter inertia member by gear teeth provided on each member. The latch member and the counter inertia member are each characterized by a moment of inertia, the ratio of which is determined by the gear ratio of the respective gear teeth. The latch assembly also restrains the actuator in its proper position when the disk drive is subject to linear shock forces.

International Classification:

G01N 3386

US Classification:

436 69

Abstract:

The present invention provides novel test cartridges for use in the assay of liquid samples and methods of carrying out such assays. These test cartridges are particularly useful in assays which include at least one step during which the sample to be assayed and one or more components of the assay system are kept separated by a pierceable member. The test cartridges comprise a housing through which the sample flows during the assay. The housing includes a holding chamber for holding the sample and a test chamber separated by a pierceable member. The test chamber further includes a partition member which has an opening therethrough and includes at least one reagent for the assay. A transfer member movably mounted in the test chamber can move towards and pierce the pierceable member and contact the liquid sample in the holding chamber. When the transfer member has been moved towards and pierces the pierceable member to contact the liquid sample and a negative pressure is created in the test chamber, liquid sample moves through the transfer member, into the test chamber and through the opening in the partition member.

Abstract:

A tilt-cab truck with the cab independently suspended on the main frame. A power device for tilting is connected to the cab and the frame at pivots spaced away from the main cab pivot. On each side of the truck a front suspension bell crank is pivoted to the cab by a main pivot and has an arm extending substantially horizontally back to a pivotal connected to the main frame, with a crank arm extending down from the rear and bearing on one end of a horizontal front air spring that is secured to the main frame at its other end. A leveling valve assembly for maintaining cab height relative to the frame is connected to the front air springs and to a source of air pressure. An anti-roll structure is rigidly connected at each end to the bell crank and extends down below it and then laterally across to the other side of the truck. A pair of lower latch assemblies are each secured to the main frame near the rear of the cab, and a pair of upper latch assemblies are each releasably secured to a lower latch assembly. A pair of horizontal rear links are each pivotally connected at a forward end to the cab and at a rear end to an upper latch assembly, and a pair of rear air springs are each mounted on an upper latch assembly with an upper end bearing against the cab.
