A differential assembly includes a case, a gearset having a pair of pinion gears and a pair of side gears, and an electrically operable coupling including a magnetically responsive fluid. The coupling is operable to selectively interconnect one of the side gears to the case. In one instance, the present invention includes a rotor having a plurality of outwardly extending blades positioned in communication with a magneto-rheological fluid. An electromagnet is selectively actuated to change the viscosity of the magneto-rheological fluid. In this manner, the differential may function as an “open” differential, a “locked” differential or a differential accommodating a limited-slip condition.

Methods and apparatus for a product authenticator and barcode scanner interlock. An example apparatus includes a barcode scanner to scan a barcode on an item and a tester to determine whether the item is authentic, wherein the tester prevents the barcode from scanning the item if the item is not authentic.

A process for adhering a decorative pattern to a flat or multi-dimensional solid involves a heat transfer powder that is sprayed or brushed onto the surface to which the image is to be applied. A design in sublimate ink is placed on a transfer film. The ink particles convert directly to gas without passing through a liquid state. The gas converts directly to a solid upon cooling filling in the gaps or pores in the heat transfer polymer. A rigid fixture is provided which has a top, front and sides onto to which solid to be decorated are snugly fit by the fixture. A solid cap which may have a soft felt-type material on the inside, which is designed to push the film in tight and level contact with the solid surface to which the design is to be imprinted may be used.

A regenerative brake of the present invention presents a hydraulic device disposed in a front hub of a bicycle wheel. The device allows the bicycle to recapture part of the kinetic energy that would otherwise be lost when braking and make use of that power either by storing it for future use or feeding it back into a power system to be used. The hydraulic device may also be stored in a rear hub of the bicycle wheel.

A method, apparatus, and computer program product are disclosed for permitting access to a data storage device while the device is being formatted. A format command is received within the device from the host. A command complete response is then transmitted to the host before the device has completed being formatted. The host waits for the command complete response before the host transmits any read or write command to the device. Read and write commands that are transmitted to the device from the host are executed while the device is still being formatted.

A unique identification number is stored in the electronic card that is attached to a disk drive, as well as in a reserved location on the disk itself. This ID number is initialized at head-disk assembly and a match between the two ID numbers is necessary for access to the data on the disk, although not for repairs to the mechanisms themselves. When a disk containing sensitive data is to be removed from a customer site, a technician briefly removes the disk and applies a jumper to specific contacts on the drive, then reinserts the drive and powers it up. This causes the ID on the electronic card to be erased, rendering the data on the drive unreadable. When the drive reaches a repair facility, the erased ID number ensures that the disk will be reformatted before being reused.
摘要:
A system and method for presenting a plurality of items of multiple types to a user. A universal data store is provided which contains a plurality of items. A portion of the items contain metadata stored in accordance with an item decoration schema. A shell presents items with corresponding metadata with an item decoration view and items without the metadata with a default display view. A shell display view is utilized to display a set of heterogeneous items and an explorer display view is provided to display items.

A system, method, and product are disclosed for verifying a condition of a storage drive's media. A command is received within the storage drive to verify the condition of the storage drive's media. In response to a receipt of the command, the storage drive attempts to read each one of the logical block addresses included in the storage drive. The condition of the media is verified by the storage drive by determining ones of the logical block addresses that are not in a readable condition.
摘要:
A multi-layer optical barcode with security features is described herein. An example method includes illuminating a first phosphor layer on a substrate with light having a first wavelength, wherein the first phosphor layer has luminescent properties such that when it is illuminated by light having the first wavelength, it emits light having a second wavelength, the first phosphor layer is divided into a first two-dimensional grid of cells arranged in a first spatial pattern, wherein each cell of the first phosphor layer corresponds to one bit of an identification code, a first portion of the first phosphor layer is removed from a first number of cells of the first two-dimensional grid of cells to expose the substrate for the first number of cells, capturing a first image of the light emitted by the first phosphor layer having the second wavelength, determining whether the first phosphor layer is authentic based on the first image, and determining the identification code based on the first image.
