摘要:
An apparatus, system, and method are disclosed for determining a read voltage threshold for solid-state storage media. A data set read module reads a data set from storage cells of solid-state storage media. The data set is originally stored in the storage cells with a known bias. A deviation module determines that a read bias for the data set deviates from the known bias. A direction module determines a direction of deviation for the data set. The direction of deviation is based on a difference between the read bias of the data set and the known bias. An adjustment module adjusts a read voltage threshold for the storage cells of the solid-state storage media based on the direction of deviation.

Projection screens include a substrate, a reflective layer on the substrate and a refractive layer on the substrate. The reflective layer includes reflective microstructures of about 5 μm to about 500 μm in size, and arranged in a first pattern to reflect light at a first spatial frequency. The refractive layer includes refractive microstructures of about 5μm to about 500μm in size, and arranged in a second pattern that is different from the first pattern, to refract light at a second spatial frequency that is different than the first spatial frequency. Related fabrication methods also are described.
摘要:
Optical microstructures, such as microlenses, are fabricated by rotating a cylindrical platform that includes a radiation sensitive layer thereon, about its axis, while simultaneously axially rastering a laser beam across at least a portion of the radiation sensitive layer. The cylindrical platform is also simultaneously translated axially while it is being rotated. The amplitude of the laser beam is continuously varied while rastering. The optical microstructures that are imaged in the radiation sensitive layer can be developed to provide a master for replicating a microlenses.

A method for providing goods or services to a subscriber of a communications network, the method incudling the steps of: (a) verifying (40) a calling party number; (b) verifying (42) the identity of the subscirber associated with the calling party number; (c) verifying (44) the age of the suibscriber; and, (d) providing (46) the subscriber with a subscriber identifier (PIN) to enable access to the goods or services. The invention is suitable for use in the provision of restricted communications services.
摘要:
A data encoder for encoding a codeword having a plurality of symbols for transmission through a data channel comprises a turbo encoder which has an interleaver, first and second RSC encoders, a puncturer and a mapper. The interleaver receives the codeword and provides an interleaved codeword. The first RSC encoder is for receiving the codeword and providing first parity bits in accordance with the codeword. The second RSC encoder is for receiving the interleaved codeword from the interleaver and providing second parity bits in accordance with the interleaved codeword. The puncturer is for receiving the codeword, the first parity bits and the second parity bits, and for puncturing at least the first and second parity bits in accordance with a pattern of a desired code rate. The mapper is for receiving the punctured parity bits, and for providing signal sets in accordance with the desired code rate.

A coupling mechanism for a work vehicle includes a coupler frame for mounting to the work vehicle and a pair of dual hook members mountable on the frame. Each dual hook member has a body with first and second hooks projecting from opposite ends the body. The ends of the body define a body plane extending therebetween. The first and second hooks project on the same side of the body plane. Each hook forms a coupling recess, and each of the recesses opens away from the body plane. The first hook is smaller than the second hook. The dual hook member is mountable in a first orientation wherein the first hook is in an operative position and is mountable in a second orientation wherein the second hook is in an operative position.
