A fan assembly includes a socket to receive a fan module, a fan flap coupled to a first side wall of the socket, and an anti-reflow device coupled to a second side wall of the socket. The fan flap moves in a curved path between a first position and a second position. The anti-reflow device has an attachment feature, an embossed feature, and a stopping feature. The attachment feature attaches the anti-reflow device to the second side wall. The embossed feature extends through a first aperture in the second side wall. The stopping feature extends through a second aperture in the second side wall and contacts the fan flap. When the fan module is removed, the stopping feature retains the fan flap in the first position to block the socket and prevent air from reflowing through the socket.

A latch includes a retention portion. The retention portion is configured to prevent a first device, coupled to the latch, from being removed while the retention portion is in a first configuration. The retention portion is configured to allow the first device to be removed while the retention portion is in a second configuration. The latch also includes a spring portion configured to allow the retention portion to transition between the first configuration and the second configuration.

A system and method for pumping fluid using a set of interconnected pump cassettes is disclosed. Each of the pump cassettes can receive a first solution in a first pumping chamber and each of the pump cassettes can receive separate second solutions in respective second pumping chambers, so that the first solution can be mixed with the separate second solutions, each said mixture capable of being placed in separate containers. The system includes a control assembly for operating each pump cassette, each pump cassette having a flexible membrane to pump fluid into and out of the pumping chambers, and each pump cassette configured for mating with a base unit that provides positive or negative pneumatic pressure to the flexible membrane.

A latch and catch assembly including a catch attachable to a first structure such as a door, and a latch mechanism attachable to a second structure such as a cabinet, the latch mechanism and the catch cooperating to secure the first structure relative to the second structure. The latch mechanism includes first and second hooks mounted for pivoting movement between an engagement position for engaging with the catch and a disengagement position for disengaging from the catch, a translating gear rail positioned between the first and second hooks coordinating pivoting movement of the first and second hooks, and an actuator mechanism for driving movement of the translating gear rail to drive the first and second hooks toward their disengagement position.

A cover unit includes a first divisional cover, and a second divisional cover. The first divisional cover and second divisional cover include a first locking portion and second locking portion, respectively. The first locking portion and second locking portion are made of an elastomer. The first locking portion and second locking portion lock to one another to couple the first divisional cover to the second divisional cover, or vice versa. The first locking portion includes a prong-shaped main tab. The second locking portion includes a main bore into which the main tab is insertable. The main tab includes a main claw disposed on the leading-end side, and locked to the main bore to inhibit the main tab from coming off from the main bore.

A latch and catch assembly including a catch attachable to a first structure such as a door, and a latch mechanism attachable to a second structure such as a cabinet, the latch mechanism and the catch cooperating to secure the first structure relative to the second structure. The latch mechanism includes first and second hooks mounted for pivoting movement between an engagement position for engaging with the catch and a disengagement position for disengaging from the catch, a translating gear rail positioned between the first and second hooks coordinating pivoting movement of the first and second hooks, and an actuator mechanism for driving movement of the translating gear rail to drive the first and second hooks toward their disengagement position.

A safe and user-friendly door, especially for logistics containers, which preferably includes a quadrilateral frame, defining the perimeter for the door. A latch is provided movably to the frame so as to be manipulated between a locking state, in which at least a distal portion of the latch protrudes outside the perimeter, and a released state, in which the distal portion is flush with or inside the perimeter. The frame also preferably includes a diagonal guide, which is configured to guide the latch between the locking state and the released state by allowing deviation of the latch along a path diagonal to the quadrilateral shape of the frame.
