Abstract: A sterile drape assembly may comprise a drape and a cable guide coupled or configured to be coupled to the drape. The drape may comprise a first portion configured to cover a medical device holder and a second portion configured to cover a portion of an arm that supports the medical device holder. The cable guide may comprise two opposing guidepost arms extending in a first direction and defining a first opening and a side arm extending laterally from one of the guidepost arms, the side arm defining a second opening. The first opening is configured to receive and route a first transmission line along a first path. The second opening is spaced from the first opening and is configured to receive and route a second transmission line along a second path spaced from the first path.

Abstract: A magazine (200) is described for portion-wise receiving individualized bulk electronic components (298). The magazine (200) comprises (a) a receiving structure (110) which comprises multiple closable receiving cavities (112, 112a), which are arranged along a longitudinal axis (100a) of the receiving structure (110); (b) a cover structure (120) which is arranged at an upper side of the receiving structure (110), displaceable along the longitudinal axis (100a), so that in a closed position of the cover structure (120) all receiving cavities (112, 112a) are covered and in one opening position of multiple opening positions at least one receiving cavity (112) is free; and (c) a closure foil (225) which encompasses the cover structure (120) along the longitudinal axis (100a) in the form of a closed tape, wherein at least a part of the closure foil (225) is releasably connected to the receiving structure (110).

Abstract: Implementations relate to a spherical wheel drive and mounting. In some implementations, a wheel mechanism includes a spherical wheel, a base, and a rotary bearing coupled to the base and contacting a surface of the spherical wheel, where the rotary bearing configured to allow the spherical wheel to rotate. The wheel mechanism includes an omni wheel coupled to the base and engaged with a surface of the spherical wheel, and an actuator coupled to the base and to the omni wheel, where the actuator configured to rotate the omni wheel to cause rotation of the spherical wheel.

Abstract: Implementations relate to a brake mechanism for a spherical wheel. In some implementations, a wheel mechanism includes a spherical wheel and a base coupled to the spherical wheel via a rotary bearing contacting a surface of the spherical wheel, where the rotary bearing is configured to allow the spherical wheel to rotate. The wheel mechanism includes a brake ring coupled to the base and configured to selectively engage and disengage the surface of the spherical wheel, where the brake ring provides friction opposing rotation of the spherical wheel when engaged.

Abstract: It should not be possible for control units for motor vehicles to be exchanged between individual motor vehicles by unauthorized persons. For a motor vehicle it should, therefore, be rendered possible for individual functionalities of a control unit to be unblocked only for a specific motor vehicle. For this purpose, a first cryptographic key and a second cryptographic key are stored in a control unit. A cryptographic device is designed to encrypt a first message initially by one of the cryptographic keys, subsequently to encrypt a result of the encryption by the other cryptographic key and, finally, to provide a result of the second encryption as third cryptographic key for an encryption and/or decryption of a further message. A method configures a control unit in a motor vehicle.
