    摘要: A light emitting diode (LED) circuit is disclosed haying a plurality of LEDs each having a respective current path. A controller may be included for controlling the LEDs. A first set of LEDs of the plurality of LEDs are connected to respective first set transistors and a first current sink to drive a constant current through each of the first set of LEDs and the first set of LEDs includes one or more LEDs, and the LED circuit may include at least one second set of LEDs of the plurality of LEDs that are connected such that the constant current in the first set of LEDs is duplicated. in the at least one second set of LEDs and the second set of LEDs includes one or more LEDs.

    摘要: A magneto-elastically-based active force sensor, used with a tow coupling between a towed and a towing vehicle or a coupling between a vehicle body and a suspension of the vehicle, which outputs a signal useful for determining forces acting on the coupling. The outputted force information may be provided by processor-enabled embedded software algorithms that take inputs from the force sensor and other sensors, may be used by one or more vehicle systems during operating of the vehicle, such as engine, braking, stability, safety, and informational systems. The force sensor includes directionally-sensitive magnetic field sensing elements inside the sensor, and shielding may be used around the sensors to reduce the influence of external magnetic fields on the sensing elements. The force sensor may be used with different tow and vehicle weight sensing coupling devices installed on different types of automobile cars and trucks.

    摘要: A system and method for controlling locomotives. The system includes a remote control unit (RCU) comprising a processing device and a computer-readable storage medium and a locomotive control unit (LCU) comprising a processing device and a computer-readable storage medium. The LCU is coupled to a locomotive control system of a locomotive for controlling the locomotive and acquiring data therefrom. The LCU is configured for listening to a common radio-frequency channel for a transmission by a network node, waiting for the channel to become free, and transmitting a message after the channel has become free. The RCU is configured for listening to a common radio-frequency channel for a transmission by a network node, waiting for the channel to become free, and transmitting a message after the channel has become free. The system may include one or more repeaters for extending an operational area of the system.

    摘要: A rack cabling system including a rack having mounted thereon a first hardware component and a patch panel housing mounted on the rack adjacent the first hardware component. The patch panel housing populates no more than a three rack unit (RU space), the patch panel housing including a first end having cable pathway openings and a second end having connector elements mounted therein. The patch panel may have a first cable pathway opening located adjacent the first side of the housing and defining a primary position and a first connector element mounted on the second end and the first connector element having a first position corresponding to the primary position of the first cable pathway opening. Cable harnesses axe routed with less than three bends of the cables between the first hardware component and the patch panel housing, so the first cable harness is terminated at the first connector element in the first position.

    摘要: The cabinet information center integrates an array of electronic sensors and controls to both standard and purpose built data center equipment cabinets to improve operational efficiencies, reduce costs and protect assets typically installed within standard equipment cabinets utilized in data centers by providing a common point of information display and cabinet interaction without the need to physically access assets and vital sensory components internal to the equipment cabinet itself. Equipment can include any standard rack mount devices such as servers, storage arrays and networking devices.
