1. Apparatus comprising:
an actuator configured to change a latch assembly from a closed condition in which an item is latched and generally held immovable relative to the latch assembly, to an open condition in which the item is unlatched and movable relative to the latch assembly,
wherein the latch assembly includes a movable catch jaw,
wherein the catch jaw in a first position is operative to engage a member operatively connected with the item when the latch assembly is in the closed condition,
wherein the catch jaw in the second position is operative to enable the member to disengage from the catch jaw when the latch assembly is in the open condition,
the actuator comprising:
a housing, wherein the housing is engageable in fixed operative connection with the latch assembly,
a drive and a gear system within the housing, wherein the gear system is in operative connection with the drive,
wherein the gear system is in operative connection with a movable release member that includes a finger that extends outside the housing, wherein the finger is movable linearly straight along a first direction outside the housing in response to operation of the drive, wherein the finger is configured to move to be in operative connection with the catch jaw such that movement of the finger in the first direction causes the catch jaw to change from being immovable from the first position to being movable from the first position to the second position.
