    • A system for controlling solid state lighting comprises a source (1) to supply any one of a range of AC or DC voltages to a plurality of light strings (3, 4, 5). The source (1) includes a power factor correction circuit 14 for controlling the power factor to the system and a separate transformer (15, 16, 17) for each light string (3, 4, 5). The current that can pass through each LED string (3, 4 and 5) is independently limited by each corresponding LED driver circuit (6, 19 and 20). The current through each LED string (3, 4 and 5) can be modified according to a feedback monitor system (18, 21 and 22) that measures parameters such as LED characteristics, forward current, temperature, and LED output intensity / colour. Each LED string (3, 4 and 5) has an independent sensor (7, 23 and 24) that monitors the voltage across each switching device in the corresponding LED driver circuits (6, 19 and 20) and utilises a control unit (8, 25 and 26) to control the voltages supplied by each corresponding transformer (15, 16 and 17) through control signals (2, 27 and 28) in response to the monitored switching device voltages.
    • 一种用于控制固态照明的系统,包括:向多个灯串(3,4,5)提供AC或DC电压范围中的任何一个的源(1)。 源(1)包括用于控制系统的功率因数的功率因数校正电路14和用于每个灯串(3,4,5)的单独的变压器(15,16,17)。 可以通过每个LED串(3,4和5)的电流由每个相应的LED驱动电路(6,19和20)独立地限制。 可以根据测量诸如LED特性,正向电流,温度和LED输出强度/颜色等参数的反馈监视系统(18,21和22)来修改通过每个LED串(3,4和5)的电流。 每个LED串(3,4和5)具有独立的传感器(7,23和24),用于监控相应的LED驱动电路(6,19和20)中每个开关装置的电压,并利用控制单元(8, 25和26),以响应于所监视的开关器件电压来控制由每个相应的变压器(15,16和17)提供的电压通过控制信号(2,27和28)。

    • Stent delivery systems and methods for making and using the same are disclosed. An example stent delivery system may include an inner member having a proximal end. A sleeve may be coupled to the inner member adjacent to the proximal end. A deployment sheath may be disposed about the inner member. A gear rack assembly may be coupled to the deployment sheath. A stent may be disposed between the inner member and the deployment sheath. A handle may be coupled to the inner member and to the deployment sheath. The handle may include an actuation member. The actuation member may be coupled to the gear rack assembly so that actuation of the actuation member shifts the longitudinal position of the gear rack assembly and the deployment sheath. An engagement mechanism may be coupled to the gear rack assembly. The engagement mechanism may be configured to engage the sleeve of the inner member so that proximal retraction of the gear rack assembly results in proximal retraction of the inner shaft.
