A fluid system includes a controller, a control valve, and a fluid manifold. At least one solenoid may be connected to the fluid manifold, the control valve, and/or the controller. A first pressure sensor may be in fluid communication with an output of the control valve. A second pressure sensor may be in fluid communication with the fluid manifold. The controller may be configured to control operation of the control valve via the at least one solenoid according to a first fluid pressure obtained via the first pressure sensor and according to a second fluid pressure obtained via the second pressure sensor.

A fluid system includes a controller, a control valve, and a fluid manifold. A first solenoid may be connected to the fluid manifold, the control valve, and/or the controller. A second solenoid may be connected to the fluid manifold, the control valve, and/or the controller. A first pressure sensor may be in fluid communication with an output of the control valve. A second pressure sensor may be in fluid communication with the fluid manifold. The controller may be configured to control operation of the control valve via the first solenoid and the second solenoid according to a first fluid pressure obtained via the first pressure sensor and according to a second fluid pressure obtained via the second pressure sensor.

Methods include determining first and second voltages of a battery before and after a load interval, determining a current through the battery during the load interval, and determining a status of the battery from the determined first and second voltages and the determined current. The load interval may include an interval during which a discharge pulse is applied to the battery, and the first and second voltages may be voltages when the battery is open circuited. The first voltage may be determined before the battery transitions from an open-circuited state to a pulse discharge state, and the second voltage may be determined after the battery transitions from the pulse discharge state to the open-circuited state. Corresponding battery monitoring apparatus and computer program products are also described.
