| 20090073614 | Voice Coil Motor - A voice coil motor has an arm for arcuate movement about a pivot, and a coil at one end of the arm. There is a permanent magnet mounted adjacent the coil. The permanent magnet has only one pole facing, and for operational co-operation with, the coil. The coil has a centre of mass and a geometric centre. The center of mass and the geometric centre are coincident. The coil is mounted to the arm perpendicular to a movement plane of the arm for the arcuate movement. | 03-19-2009 |
| 20100253170 | LOW PROFILE SPINDLE MOTOR - A low profile spindle motor for supporting and rotating media disk or disks of a hard disk drive includes a plurality of stator teeth, a winding layer which may be formed by printed circuit board or the like, and a rotor. The plurality of stator teeth are disposed in an annular region surrounding an axis of rotation of the motor, and have projected ends for increasing the tooth area facing a magnet ring of the rotor. The winding layer has a plurality of windings disposed surrounding the axis of rotation. Each winding is coupled to one of the plurality of stator teeth. The magnet ring is positioned radially spaced apart and coplanar with the annular region. The magnet ring has magnetic poles annularly distributed to generate magnetic fluxes along radial direction. Spindle motor formed according to the invention has a low profile, improved performance and manufacturability. | 10-07-2010 |
| 20110133589 | LOW PROFILE PERMANENT MAGNET SYNCHRONOUS MOTOR WITH SEGMENT STRUCTURE - A low profile permanent magnet synchronous motor with segment structure. In accordance with this invention, a stator assembly for an electromagnetic motor is provided. The stator assembly has a first stator core and a second stator core that couple windings. Teeth extend outward from each stator core and through the windings to contact the other stator core. | 06-09-2011 |

| 20090070394 | CANONICAL SIGNED DIGIT MULTIPLIER - A multiplier is able to multiply an input data value by a selected constant value in CSD form. The selected constant value has a plurality of pairs of bits, and the multiplier includes multiplexers, each controlled by a respective pair of bits of the selected constant value. Each of the multiplexers has a plurality of inputs, and is connected to receive the input data value, the inverse of the input data value, and all zeros on said inputs, and it is controlled such that it outputs either the input data value, the inverse of the input data value, or all zeros, depending on the values of the respective pair of bits of the selected constant value. Variable shift blocks are each connected to receive an input from a respective one of said multiplexers, and are each adapted to shift their received input by a first bit shift value or a second bit shift value, depending on the values of the respective pair of bits of the selected constant value, wherein the first bit shift value and the second bit shift value differ by 1. The multiplier also includes combination circuitry, for receiving the outputs from the plurality of shift blocks, and for combining the outputs from the plurality of shift blocks and applying further bit shifts, to form an output value equal to the result of multiplying the input data value by the selected constant value. | 03-12-2009 |
| 20090213981 | LOW-POWER REGISTER ARRAY FOR FAST SHIFT OPERATIONS - A data register ( | 08-27-2009 |
| 20100011043 | FAST FOURIER TRANSFORM ARCHITECTURE - A last fourier transform architecture has parallel data processing paths. Input data is applied to the parallel data processing paths in a repeating sequence, and processed in those paths. Data sequencers are used to combine the outputs from the data processing paths into the required sequence. | 01-14-2010 |

| 20110200986 | BIO-ASSAY USING LIQUID CRYSTALS - There is provided a method, an in vitro method and a detection system for detecting the presence of at least one biological molecule in at least one sample. The method can include, for example, providing a sample and/or a binding agent to a contact portion of a surface by way of at least one microfluidic channel; disposing a liquid crystal at the contact portion; determining whether the orientation of the liquid crystal changes after the sample contacts the binding agent, indicating the presence of the biological molecule; and determining length of bright region of the liquid crystal and/or change in interference color of said liquid crystal, and consequently indicating the quantity of said biological molecule. Also disclosed are methods of detecting biological molecules using at least one 4′-pentyl-biphenyl-4-R, where R may be at least one functional group selected from carboxylic acid, amine, aldehyde, and oligopeptide. | 08-18-2011 |
