Abstract:

Disclosed is a disk drive that provides for internal disk drive temperature estimation. The disk drive includes an actuator, a head attached to the actuator, a disk to store data, a preamplifier connected to the head to amplify read and write signals, and a processor for controlling operations in the disk drive including moving the actuator such that the head is moved to read data from and write data to the disk. The processor under the control of a program is further utilized to calculate a junction temperature (J) based on a breakthrough voltage of the preamplifier, apply a filter to the calculated Jto compensate for temperature noise, and to estimate an internal disk drive temperature based upon the filtered J.

US Classification:

438260, 257317

Abstract:

A nonvolatile memory cell includes a substrate comprising a source, drain, and channel between the source and the drain. A tunnel dielectric layer overlies the channel, and a localized charge storage layer is disposed between the tunnel dielectric layer and a control dielectric layer. A gate electrode has a first surface adjacent to the control dielectric layer, and the first surface includes a midsection and two edge portions. According to one embodiment, the midsection defines a plane, and at least one edge portion extends away from the plane. Preferably, the edge portion extending away from the plane converges toward an opposing second surface of the gate electrode. According to another embodiment, the gate electrode of the nonvolatile memory cell includes a first sublayer and a second sublayer of a different width on the first sublayer.

Abstract:

A health-diet sandal which comprises a shoe sole having a heel portion adapted for biasing against an arch portion of a wearer's foot, and a shoe body comprising a vamp attached on top of the shoe sole to define a foot chamber between the vamp and the shoe sole, and an elongated elastic unit having two ends extended from two sides of the vamp adapted for mounting behind a heel of the wearer's foot, so as to hold the wearer's foot within the foot chamber in position. Therefore, the nervous distributed around the arch portion of the wearer's foot is able to be stimulated by the heel portion of the shoe sole for improving the wearer's blood circulation and metabolism.

International Classification:

H04N 7/26

US Classification:

386124, 386E05001

Abstract:

A method and apparatus for transferring protected digital AV content. The apparatus includes a specially adapted microprocessor with firmware allowing the microprocessor to control and transmit for storage and for display device digital AV content data in the form of digital signals. A source storage device is connected to the microprocessor by means of link At least one sink storage device is also connected to microprocessor by link The firmware allows the microprocessor to time the amount of material transferred to sink to that allowed by the appropriate copy protection specification. The method limits the amount of data transferred to the programmed amount for example one second slices ending on a frame end. After each increment of data is transferred the amount remaining on source is deleted. The process continues until all of the desired material is transferred from source to sink
