1. A system for maintaining hydraulic pressure at a hydraulic accumulator, the system comprising:
a pressure sensor coupled to a control unit;
a check valve coupled to the pressure sensor through a first connector; and
a pump coupled to the check valve through a second connector and coupled to the control unit;
wherein the pressure sensor is configured to mechanically detect a pressure at the first connector,
the pressure sensor is further configured to transmit a signal to the control unit when the pressure at the first connector falls below a first threshold,
the pressure sensor is further configured to transmit a second signal to the control unit when the pressure at the first connector exceeds a second threshold,
the control unit is configured to control the pump to urge, at a first time, hydraulic fluid through the check valve into the first connector through the second connector when the control unit receives the signal, and
wherein the control unit is further configured to control the pump to cease urging hydraulic fluid through the check valve into the first connector through the second connector when the control unit receives the second signal.
