An implantable blood pump includes motor control circuitry and power electronics circuitry integrated within the implantable pump body. The motor control circuitry and power electronics circuitry is configured to energize and control motor windings to rotate the pump rotor and impeller. Additional control circuitry and power electronics circuitry may be integrated within the pump housing to energize and control magnetic bearings of a magnetic levitation pump. A percutaneous cable coupled between the implantable blood pump and an extracorporeal monitor includes a reduced number of leads to provide power and control signals to the implantable blood pump. Wireless communication between the extracorporeal monitor and the integrated power electronics and control circuitry facilitates the use of a percutaneous cable with as few as two leads for providing power to the implantable pump.

A vaneless compressor containment design has an inner bolt circle with more than three fasteners situated in the vaneless space to cut up tri-hub pieces to smaller pieces prior to reaching an outer bolt circle and its associated flange. This containment design may allow a thinner radial wall thickness for the outermost flange as compared to the conventional design. The thinner radial wall thickness may reduce the weight of the compressor. This weight reduction may be achieved with little or no increase in the compressor space envelope.

A centrifugal compressor may comprise a wheel and a pipe diffuser. The pipe diffuser may comprise an annular pipe diffuser section and at least one cylindrical hole passing through the annular pipe diffuser section for compressing gas emerging from the wheel. The at least one cylindrical hole may have an axis that is slanted at an angle A relative to a plane that is orthogonal to an axis of rotation of the compressor.

An interface for an integrated circuit (IC) device. The interface includes a scrambler to combine a plurality of plaintext data streams and a pseudorandom key sequence. The scrambler includes a pseudorandom number (PRN) source and a combiner. The PRN source provides a pseudorandom number. The pseudorandom key sequence is based on the pseudorandom number. The combiner receives the plurality of plaintext data streams in parallel and output a corresponding plurality of ciphertext data streams in parallel to another IC device interface. The interface also may include a descrambler to separate a pseudorandom key sequence out of a plurality of parallel ciphertext data streams. By scrambling plaintext data streams and descrambling ciphertext data streams in parallel, the data transmission rate on the IC device may be slower than a data transmission rate used to transfer data between IC devices.

A method for etching a polysilicon gate structure in a plasma etch chamber is provided. The method initiates with defining a pattern protecting a polysilicon film to be etched. Then, a plasma is generated. Next, substantially all of the polysilicon film that is unprotected is etched. Then, a silicon containing gas is introduced and a remainder of the polysilicon film is etched while introducing a silicon containing gas. An etch chamber configured to introduce a silicon containing gas during an etch process is also provided.

A method and related apparatus for reordering access requests used to access main memory of a data processing system. The method includes receiving one or more access requests for accessing the memory device in a first predetermined order, and reordering the access requests in a second predetermined order to be processed in a request queue by relocating a first access request to follow a second access request accessing a same memory page to increase processing efficiency. In addition, the relocating is prohibited if it increases a processing latency for a third access request to exceed a predetermined limit.

A method for a graphics chip to access data stored in a system memory of a computer device is disclosed. The method includes using a memory controller to set a block capacity value; using the memory controller to divide a plurality of read requests corresponding to a predetermined request sequence into a plurality of request groups, wherein a total amount of data required by read requests grouped in each request group is less than the block capacity value; and using the memory controller to adjust a request sequence corresponding to read requests grouped in each request group for retrieving data stored at different N pages so that a memory device only performs N−1 page switching operations.

A help utility application assists users to complete step-by-step processes in real time by providing information associated with each step in a sequence of data entry steps. The help utility application provides context-based functionality by determining a particular step in the sequence at which a user needs help. The help utility application also provides context-based functionality by branching based on data the user enters in one or more particular steps.

The ball type camera able of changing a lens module comprises: a swivel table mechanism for rotating in a horizontal plane for 360 degrees without segmentation and a rocking mechanism for rotating up and down for 90 degrees without segmentation. Wherein the rocking mechanism has a rotation seat driven by the swivel table mechanism for rotating for 360 degrees and a rocking member; the rotation seat is mounted thereon with a motor and a driving gear, the rocking member mounted with the lens module is pivotally connected to the rotation seat, the rocking member has thereon a sheet gear engaging with the driving gear; the motor on the rotation seat runs to move the sheet gear through transmitting of the driving gear to make the rocking member move the lens module on the vertical plane for rotating up and down for 90 degrees without segmentation; With this combination, the lens module can be removed from the rocking member for changing.
