    摘要: A method for controlling a hydraulic flow within a powertrain comprising an electromechanical transmission mechanically-operatively coupled to an engine adapted to selectively transmit power to an output, wherein the transmission utilizes a hydraulic control system serving a number of hydraulic oil consuming functions includes monitoring minimum hydraulic pressure requirements for each of the functions, determining a requested hydraulic pressure based upon the monitoring minimum hydraulic pressure requirements and physical limits of the hydraulic control system including a maximum pressure, determining a desired flow utilizing a hydraulic control system flow model based upon the requested hydraulic pressure, and utilizing the desired flow to control an auxiliary hydraulic pump.

    摘要: An access assembly for use during a medical procedure including accessing a selected bone structure or target tissue, includes a cannula and stylet with an alignment guide removably attached to the cannula. The alignment guide shows the relative alignment between the access assembly and the viewing axis of an imaging system, thereby making placement of the access assembly more accurate. Once a desired alignment is achieved, the access assembly may then be advanced further towards the target tissue until a desired placement is achieved.
