摘要:
An air humidifying system includes an air humidifying device including a humidifying unit, having a dry air inlet and a humidified air outlet, for humidifying a flow of dry air from the dry air inlet to a humidified air exiting at the humidified air outlet. An air filtering unit has an air filtering inlet for guiding an ambient air as the dry air and an air filtering outlet communicating with the dry air inlet of the humidifying unit for purifying the dry air before entering into the humidifying unit. An air supplying unit has an air inlet port communicating with the humidified air outlet of the humidifying unit and an air outlet port adapted for communicating with an air inlet of the fuel cell stack, wherein the air supplying unit is adapted for guiding the humidified air into the fuel cell stack in a pressurized manner.

This disclosure describes techniques to utilize pluggable photonics module in high data rates optical communications systems such as some coherent optical communications system. The pluggable photonics module plugs into a host board. The host board includes a processor that compensates for distortion caused by data streams traveling across the pluggable interfaces that the pluggable photonics module and host board use to couple to one another.

An output voltage regulator of step-down switching power converters is described, with the regulator provided with digitally adjusted output voltage. It solves the problem of low regulation due to low error amplifier (EA) gain. This invention includes a power converter with the function of Digitally Error Correction, having Logic Control, EA, PWM comparator, Driver, power devices and passive components. A Digital Calibration Circuit whose input terminal is connected to the output voltage and output terminal is connected to the error signal. When the output voltage exceeds the tolerance range, this Digital Calibration Circuit will increase or decrease the error signal step by step, keeping the output voltage in the tolerance range. The Digital Calibration Circuit can be applied not only in nanometer scale process, but also in traditional process. For those power converters in traditional process, it is also quite promising in applications.

A method for filtering a notification being provided from an application to a user of a social networking system based on an action of the user is described. The method starts by receiving the notification from the application to the user. If the notification is a first notification sent from the application to the user, the notification is displayed to the user with (i) a prompting message that includes a selectable opt in image, and (ii) a selectable opt out image. The prompting message includes a request to opt in to receiving notifications from the application. If the notification is not the first notification sent from the application to the user, the method determines whether to display the notification to the user by determining whether the user previously opted in to notifications from the application and whether click-through rate (CTR) of notifications from the application is greater than CTR threshold.
