Abstract: An ion filter for circulating coolant in a fuel cell stack of a fuel cell vehicle includes a housing including an inlet configured so that a fluid is introduced and an outlet configured so that the fluid is discharged, a filter element accommodated in the housing to filter the fluid, a valve assembly provided on the inlet and configured to operate the flow of the fluid introduced into the housing through the inlet to be allowed or blocked, and a gate member provided in the housing and configured to adjust an operation of the valve assembly.

Abstract: Embodiments of the invention are generally directed to simultaneous transmission of clock and bidirectional data over a communication channel. An embodiment of a transmitting device includes a modulator to generate a modulated signal including a clock signal and a data signal, the clock signal being modulated by a first signal edge of the modulated signal and the data signal being modulated by a position of a second signal edge of the modulated signal; a driver to drive the modulated signal on a communication channel; an echo canceller to subtract reflected signals on the communication channel; and a data recovery module to recover a signal received on the communication channel, the received signal being encoded by Return-to-Zero (RZ) encoding, the signal being received simultaneously with driving the modulated signal on the communication channel.

Abstract: A charge pump circuit includes switch circuit modules and current modules. The number of switch circuit modules that are coupled to receive current from one of the current modules is variable. The output current of the charge pump circuit increases as more of the switch circuit modules are coupled to receive current from the current modules. The net on-resistance of the switch circuit modules decreases as more of the switch circuit modules are coupled to receive current from the current modules. Charge coupling caused by the net parasitic gate-to-drain capacitance of switching transistors in the switch circuit modules is reduced at smaller output current settings of the charge pump circuit.
