摘要： Techniques for optimizing the power consumption of existing low cost multi-gain state power amplifiers (PA) to increase the talk time of wireless communication devices are described. In an exemplary embodiment a device, such as a baseband processor, operates to set a multistage PA having at least two gain states for amplifying a transmit signal to a lowest power consuming gain state. The device calculates a transition power level as a function of an identified maximum power reduction (MPR) value and switches the PA to a higher gain state from a lower gain state when a transmission power level is higher than the calculated transition power level.

摘要： An endovascular conduit device and method for use during cardiac lead extraction and other vascular procedures is presented. The endovascular conduit device includes an outer-sheath, a conduit member, a lumen member, and an inflation member to control the flow of fluid within the conduit member. The endovascular conduit device may be positioned intravascularly as cardiac lead extraction or other procedures are performed. If necessary, as in the case of a vascular tear, the endovascular conduit device further includes expandable members that are activated to allow blood to be forced into the channel of the conduit member. Blood may then be contained and directed safely to bypass the area of vessel injury. In doing so, a catastrophic circulatory collapse or shock is prevented.
