Example weather barrier apparatus are disclosed herein. An example weather barrier apparatus includes a support structure having a first end and a second end spaced from the first end, where the first end is to couple to a wall and the second end is movable relative to the first end. A seal is pivotally coupled to the second end of the support structure to define a pivot axis. The seal has a first sealing portion and a second sealing portion spaced from the first sealing portion. The first sealing portion is to engage a rear edge of a vehicle and the second sealing portion is to engage a surface of the vehicle spaced from the rear edge of the vehicle when the vehicle is in engagement with the seal.

Vehicle-actuated weather barrier apparatus

Example weather barrier apparatus are disclosed herein. An example weather barrier apparatus includes a mount to couple to a wall of a loading dock and a seal coupled to the mount. The seal includes an outer flexible sheet having a first end and a second end. The seal includes an inner flexible sheet having a third end and a fourth end. The third end of the inner flexible sheet couples to the first end of the outer flexible sheet and the fourth end of the inner flexible sheet couples to the second end of the outer flexible sheet. The inner flexible sheet provides an edge seal and a surface seal. The edge seal engages a rearward facing edge of a vehicle and the surface seal engages surface panel of the vehicle when the vehicle is in engagement with the seal. A guide movably couples the outer flexible sheet and the inner flexible sheet. The guide is positioned between the respective ends of the inner and outer flexible sheets. The guide spaces apart a portion of the inner flexible sheet from a portion of the outer flexible sheet. The inner flexible sheet, the outer flexible sheet and the guide are to move between a first position and a second position in response to a force imparted to the weather barrier by the vehicle when the vehicle is in engagement with the inner flexible sheet to enable at least one of the edge seal to conform to a shape of the rearward facing edge of the vehicle or the surface seal to conform to a shape of the surface panel of the vehicle.

Example weather barrier apparatus are disclosed herein. An example weather barrier apparatus includes a curtain having a plurality of compressible tubes positioned between a first end of the curtain and a second end of the curtain. The compressible tubes move between a collapsed position when the curtain is in a relaxed condition and an expanded position when the curtain is a taut condition.

Example weather barrier apparatus are disclosed herein. An example weather barrier apparatus disclosed herein include rear edge seals to sealingly engage a rearward facing edge of a vehicle parked at a loading dock. In some examples, the rear edge seal is part of a pivotal upper or side seal member that also includes a surface seal. The surface seal is spaced apart from the edge seal and is to sealingly engage a side or upper surface of the vehicle. In some examples, the vehicle's side surface is the outward facing surface of the vehicle's swung-open door. In some examples, the vehicle backing against the edge seal is what deploys the side seal. Some example weather barrier apparatus disclosed herein include an upper seal member and two side seal members, where vehicle-activated movement of the upper seal and side seal members are coordinated to seek and seal against rear corners of a cargo opening of the vehicle. In some examples, one or more seal members lengthen in response to the size and position of the vehicle.

One or more embodiments of a flexible manipulator tools are provided. The flexible manipulator tool can include a distal end movable in at least one manipulation plane with respect to a proximal end. The flexible manipulator tool can also include at least two cheeks extending side by side to and spaced apart from each other.

Manipulator tool and holding and/or expanding tool with at least one manipulator tool

A watercraft having a plurality of flexible section secured to a mount, having a drive assembly, wherein the water craft can move the flexible section upwardly and downwardly to propel the watercraft through the water.

Methods and devices for sending, transmitting and/or receiving information by means of waves, in which an information signal of a carrier wave is impressed, whose frequency is continuously changed to form at least one carrier sweep in a predetermined time interval and in which the information signal is filtered to separate multipath components after being received in the frequency range or is cleaned of noise portions and then evaluated with respect to the information-bearing signal parameters.

Method and devices for transmitting and receiving information

A rotor through which a fluid flows in a main direction of flow, provided with at least one rotor blade, the rotor blade being arranged to rotate about a rotor axis. The rotor blade extends away from the axis of rotation into the field. To reduce the trailed tip vortex at the end of the rotor blades, the fluidic losses, and flow noise, the rotor blade is split in at least two partial blades at a set distance from the axis of rotation and forms a loop. One partial blade extends in the direction of rotation in relation to the rotor blade. The other partial blade extends in a direction opposite the direction of rotation to the rotor blade. The two partial blades are interconnected in one piece at their ends, to encompass a loop surface extending essentially crosswise to the main direction of flow, through which the fluid flows.

Rotor with a split rotor blade

A process and system for the transfer of information, which is suitable in particular for digital information transfer. At least one information signal is created, consisting of at least one reference component and at least one information component, wherein at least one of these components has a temporally continuous frequency change during the transfer and, in addition, the reference component and the information component form discrete states for the provision of bit patterns. After receiving, the at least one component with frequency change is transferred into constant intermediate frequencies. From the spectrum of the constant intermediate frequencies, in each case the best-suited signal components are selected, separated as constant frequencies from interference portions and evaluated with regard to the relevant information parameters. This allows a signal transfer with high quality and high transfer rate, even over great distances, for example, under water. Furthermore, a suitable evaluation system is described.
