    • Described are on-die termination (ODT) systems and methods that facilitate high-speed communication between a transmitter die and a receiver die interconnected via one or more signal transmission lines. An ODT control system in accordance with one embodiment calibrates and maintains the termination resistances for the signal transmission lines. The ODT control system derives a number of calibration currents from precision voltage and resistance references and distributes the reference currents to a number of transmitters. Each transmitter then derives an ODT calibration signal using the respective reference current and another precision resistor, and then employs the calibration signal to calibrate local termination elements. Distributing calibrated currents provides excellent noise immunity, while limiting the requisite number of external voltage references reduces cost.
    • 描述了促进经由一个或多个信号传输线互连的发射器管芯和接收器管芯之间的高速通信的管芯端接(ODT)系统和方法。 根据一个实施例的ODT控制系统校准并维持信号传输线路的终端电阻。 ODT控制系统从精密电压和电阻参考中导出多个校准电流,并将参考电流分配给多个发射器。 然后,每个发射器使用相应的参考电流和另一个精密电阻器导出ODT校准信号,然后使用校准信号来校准局部终端元件。 分配校准电流提供了出色的抗干扰能力,同时限制了外部参考电压的必要数量可以降低成本。

    • An infant thermometer assembly includes a cover portion and a thermometer portion pivotably coupled to the cover portion and pivotably movable relative to the cover portion about a pivot axis between a use position and a stowed position. The thermometer portion includes a probe and a housing coupled to the probe. The housing includes a display screen and a power button. The cover portion includes a cavity formed to receive at least a portion of the housing of the thermometer portion in the use and stowed positions and a cut-out formed to receive the probe of the thermometer portion in the stowed position.

    • A security gate for closing a passage has a pair of panels movable translationally with respect to one another to alter the effective width of the gate. An actuating mechanism for forcing the opposite ends of the panels against the sides of the passage includes a handle mounted on one of the panels controlling a latching device operative for locking the handle in a fixed relationship with respect to the other of the panels. The latching device in accordance with one embodiment includes a rack and brake. When the latch is engaged, a cam also controlled by the handle engages the panel on which the handle is mounted to force the two panels translationally further apart so as to bear firmly against the sides of the passage to hold the gate in position.
    • 用于封闭通道的安全门具有可相对于彼此平移运动的一对面板,以改变门的有效宽度。 用于迫使面板的相对端抵靠通道的侧面的致动机构包括安装在一个面板上的手柄,其控制用于相对于另一个面板以固定关系锁定手柄的闭锁装置。 根据一个实施例的闩锁装置包括齿条和制动器。 当闩锁接合时,也由手柄控制的凸轮接合安装手柄的面板,以迫使两个面板平移更远地分开,以便牢固地抵靠通道的侧面以将门保持在适当位置。
