Abstract: A cooling device including a housing frame, a heat exchanger, an electrically drivable fan unit, a control unit, and a sensor unit. The housing frame can be disposed on a first surface of the heat exchanger. The fan unit is configured so that, during operation of the fan unit, a first air flow is produced toward the first surface of the heat exchanger. The fan unit is accommodated in a recess of the housing frame. The housing frame has at least one air channel having an air inlet opening and an air outlet opening, the air channel being formed parallel to the first surface of the heat exchanger, allowing a second air flow to pass through the air channel along the first surface. A measured quantity is recorded by the sensor unit, and the fan unit is driven by the control unit as a function of the recorded measured quantity.

Abstract: An interpupillary distance adjustment mechanism can be used to set the interpupillary distance (IPD) between a pair of independently pivoting monocular assemblies of a binocular optical device. Once the IPD of the binocular optical device has been set to match the IPD of a user, the interpupillary distance adjustment mechanism acts as a rotational stop enabling the user to return a monocular assembly of the binocular optical device to the desired position when the monocular assembly is moved from the stowed position to the operation position. An example interpupillary distance adjustment mechanism comprises: a housing adapted for attachment to a binocular optical device, a pair of set-stop pins, and a pair of thumb dials. The housing includes a pair of set-stop pin sheaths, one for each set-stop pin. Each thumb dial is operably connected to a set-stop pin and configured to longitudinally displace the operably connected set-stop pin from its sheath.

Abstract: A dual tube night vision device comprises a pair of independently pivoting night-vision monoculars connected to a bridge member. Each night-vision monocular is attached to the bridge member by a rotating arm and comprises a pod containing an image intensifier tube. Each arm allows the attached night-vision monocular to move through a rotational travel path, between a stowed position and a deployed position. The dual tube night vision device is configured to detect when the night-vision monoculars are, individually or collectively, moved to a stowed position and then temporarily cut off power to the stowed monocular(s) to increase battery runtime. Power is automatically restored, individually or simultaneously, to the night-vision monoculars when they are rotated back to the deployed positions. The dual tube night vision device uses one or more accelerometers to detect when the night-vision monoculars, individually or collectively, are in the stowed position or the deployed position.

Abstract: A device for cleaning at least a partial region of a housing surface. The device includes a first structure having an outer surface and an inner surface, the outer surface being situated opposite to the inner surface, the inner surface being able to be disposed on the partial region of the housing surface, and a second structure having an outer surface and an inner surface, the outer surface of the second structure being situated opposite to the inner surface of the second structure, wherein the inner surface of the second structure is disposed on the outer surface of the first structure, the first structure being deformable along a first axis by a fluid which is able to be conducted between the first structure and the second structure and the second structure being movable along a second axis, the second axis being disposed perpendicular to the first axis.

Abstract: A laminated multilayer polymer containing film (P) comprises at least one layer comprising at least one copolyamide wherein the copolyamide is prepared by polymerizing the following components: (A) 15% to 84% by weight of at least one lactam, (B) 16% to 85% by weight of a monomer mixture (M) comprising the following components: (B1) at least one C32-C40 dimer acid and (B2) at least one C4-C12 diamine, where the percentages by weight of components (A) and (B) are each based on the sum total of the percentages by weight of components (A) and (B) and wherein the laminated multilayer polymer containing film (P) comprises at least one further layer, where the at least one further layer is selected from the group consisting of (i) at least one further polymer (FP) selected from the group consisting of polyolefins, poly(ethylene-vinyl alcohols), poly(ethylene-vinyl acetates), polyethylene terephthalates, polyvinylidene chlorides, maleic anhydride-grafted polyolefins, polyesters and ionomers and (ii) aluminum metal a
