摘要： A DC fan, or lot of DC fans is characterized at a constant voltage to determine the variation of their rotational speed with respect to altitude. Many such DC fans will have a substantially linear response in speed with respect to altitude. From this relationship, a converter is constructed to convert the rotational speed into an altitude. The converter may be a discrete electronic device including a look up table or capable of performing the arithmetic algorithm representing the relationship between fan speed and altitude. Alternatively, the converter may be incorporated into the system to be cooled by the DC fan. For example, it may be a software routine run by the computer that the DC fan is used to cool.

摘要： A heat-generating device is characterized to determine the relationship between the speed of a DC cooling fan, and the thermal margin of the heat-generating device. Since the speed of DC fans is substantially linear with respect to their input voltage, the speed of the fan may be adjusted within a system to provide the speed necessary for cooling needs. An altitude is input to a converter which uses the characterization of the heat-generating device to determine a fan speed necessary at that altitude to cool the heat-generating device to a temperature within its operating range. The converter then controls the voltage supplied to the DC fan to result in the needed fan speed.

摘要： A pump or DC fan used to cool an electronic system is monitored for speed. When the pump or fan encounters an unexpected increase in impedance, such as an obstruction or a bearing anomaly, the controller temporarily increases the power to the pump or fan to overcome the impedance, and optionally notifies the user of the pump or fan problem. Also, when the pump or fan impedance returns to a normal range, the controller returns the power to the pump or fan to normal levels. In some embodiments, the controller may supply more power to the pump or fan than specified by the manufacturer to temporarily over come the increased impedance or pending failure of the pump or fan. This increased power allows the fan or pump to operate at a speed necessary for cooling an electronic system during a temporary increase in impedance, or during a slow degradation of the efficiency of the fan or pump.
摘要翻译： 监控用于冷却电子系统的泵或直流风扇的速度。 当泵或风扇遇到阻塞（例如阻塞或轴承异常）的意外增加时，控制器暂时增加泵或风扇的功率以克服阻抗，并且可选地通知用户泵或风扇问题。 此外，当泵或风扇阻抗恢复到正常范围时，控制器将泵或风扇的电源恢复到正常水平。 在一些实施例中，控制器可以比制造商提供比泵或风扇更多的功率，以暂时超过泵或风扇的增加的阻抗或未决的故障。 这种增加的功率允许风扇或泵在暂时增加阻抗期间或在风扇或泵的效率的缓慢降低期间以冷却电子系统所需的速度运行。

摘要： An earphone has a body housing a transducer that is capable of generating an acoustic signal and directing the acoustic signal to an outlet in the body, the body being positionable in, on, or near an ear of user so that the acoustic signal can be directed into the ear canal of the user. The earphone also has an ear coupling mechanism comprising a sealing mechanism with a sealing member that is adapted to contact a portion of the ear of the user to at least partially create a seal between the ear canal and the external environment and a venting mechanism capable of venting air between the ear canal and the external environment, the venting mechanism comprising an air conduit that is adapted to communicate on one end with the ear canal and at another end with the external environment so that air can flow through the conduit to equalize a pressure differential across the sealing mechanism. The air conduit is sized and shaped so as to provide an improved audio performance over an earphone without the air conduit.

摘要： A chain tension sensor for a chain conveyor, the conveyor including a frame and a chain having a plurality of flights. The tension sensor includes a reaction arm and a load sensing pin. The reaction arm includes a first end, a second end opposite the first end, and a load pad. The first end is pivotably coupled to the frame by a pivot pin defining a pivot axis. The load pad is adjacent the conveyor chain and positioned to contact flights passing the load pad. The flights contacting the load pad exert a force on the reaction in a direction that is perpendicular to the pivot axis. The load sensing pin is coupled to the reaction arm such that the load sensing pin senses the force that is exerted by the flights.
