A reflective sidewall is used to redirect the output emission from edge-emitting lasers through an optical element (e.g., a diffuser, lens, etc.). A common electrical pad centered inside the package provides p-side connection to multiple laser diodes (i.e. for power scalability). Thick plating (e.g. 75 um to 125 um) with a heat and electrically conductive material, e.g. copper, on a raised bonding area of a substrate provides good heat dissipation and spreading to the substrate layer during operation. The composite CTE of the substrate layer, e.g. AlN, and the heat/electrical conductive plating, e.g. Cu, substantially matches well with the laser substrates, e.g. GaAs-based, without the requirement for an additional submount.	01-24-2013

Due to different shapes and sizes of prostates as well as orientation of prostate with respect to an ultrasound probe during image, acquisition a simple prostate model (e.g., ellipse) with a fixed plan may not be sufficient. Accordingly, it has been determined that a deformable shape model with integrated biopsy target locations/sites may be fit to a prostate image to provide improved automated biopsy targeting.	02-19-2009
20090324041	APPARATUS FOR REAL-TIME 3D BIOPSY - A method and apparatus are disclosed for performing software guided prostate biopsy to extract cancerous tissue. The method significantly improves on the current system by accelerating all computations using a graphical processing unit (GPU) keeping the accuracy of biopsy target locations within tolerance. The result is the computation of target locations to guide biopsy using statistical priors of cancers from a large population, as well as based on previous biopsy locations for the same patient, and finally via mapping protocols with predefined needle configurations onto the patient's current ultrasound image.	12-31-2009

20110302391	DIGITAL SIGNAL PROCESSOR - A digital signal processor comprises an instruction analysis unit, a digital signal processor (DSP) core and a memory unit. The instruction analysis unit receives an instruction and determines the required bit width M for the data process corresponding to the instruction. The DSP core performs the M-bit data process based on the bit width M determined by the instruction analysis unit, and the memory unit stores multiple data and performs the M-bit access based on the bit width M determined by the instruction analysis unit thereby allowing the DSP core to access, and at lest one available space in the memory unit will be adjusted such that only the access space having the bit width M for the operation corresponding to the instruction will be open in each access, thereby effectively achieving the effect of power-saving.	12-08-2011
