Abstract: Polymer catheters and guidewires for use in intravascular surgery, and more particularly polymer catheters and guidewires micro-machined with a micro-cutting machine to provide sufficient flexibility to travel through a patient's vasculature while retaining sufficient torquability to transmit torque from a proximal end to the distal end of the catheter or guidewire, and methods of producing the same.

Abstract: This disclosure describes a micro-cutting machine for forming cuts in catheters, guidewires, and similar products. The micro-cutting machine can directly control the dimensions of the resultant beams being cut into these types of products, and can also capture images of each cut for feedback control and accuracy verification. The micro-cutting machine has two cutting blades each with cutting edges aligned with a vertical axis. Motors operate to move the cutting blades in a direction perpendicular to the longitudinal axis of the stock material being cut to form a pair of opposing grooves in the stock material with each cut.

Abstract: Methods and systems for providing gesture-based power management for a wearable portable electronic device with display are described. An inertial sensor is calibrated to a reference orientation relative to gravity. Motion of the portable device is tracked with respect to the reference orientation, and the display is enabled when the device is within a viewable range, wherein the viewable range is a predefined rotational angle range in each of x, y, and z axis, to a user based upon a position of the device with respect to the reference orientation. Furthermore, the display is turned off if an object is detected within a predetermined distance of the display for a predetermined amount of time.

Abstract: An apparatus for controlling a dynamic random access memory (DRAM), the apparatus comprising an interface to transmit to the DRAM a first code to indicate that first data is to be written to the DRAM. The first code is to be sampled by the DRAM and held by the DRAM for a first period of time before it is issued inside the DRAM. The interface is further to transmit the first data that is to be sampled by the DRAM after a second period of time has elapsed from when the first code is sampled by the DRAM. The interface is further to transmit a second code, different from the first code, to indicate that second data is to be read from the DRAM. The second code is to be sampled by the DRAM on one or more edges of the external clock signal.
