Abstract: Training apparatus (1) for at least one user (2), including a weapon (3) and consisting of a device for detecting a hit and a display device (6) for displaying virtual targets (13), wherein: the display device (6), worn by the user, takes the form of an augmented reality (AR) device, which visually displays to the user (2) at least the target (13) to be hit; the weapon (3) takes the form of a firearm, which fires at least one projectile (7); and the projectile (7) is detected by at least one laser (9, 11), evaluated and visually displayed on the display device (6).

Abstract: A ventilation outlet for a ventilation system of a motor vehicle for directionally supplying a passenger compartment of the motor vehicle with an air flow flowing in a flow direction, having a ventilation duct for passing the air flow, with a duct wall for circumferentially delimiting the ventilation duct and a ventilation duct outlet opening for discharging the air flow into the passenger compartment, and a first air guide louver arranged in the ventilation duct and having a louver head portion and a louver head portion for deflecting the air flow, wherein the first air guide louver is held pivotably relative to the ventilation duct about a pivot axis between a first position and a second position, wherein the pivot axis runs through the louver head portion and is arranged adjacent to the ventilation duct outlet opening.

Abstract: Magnetic transmissions and related methods are described. In one embodiment, an apparatus includes a magnetic screw comprising an elongate body, a nut selectively magnetically coupled to the magnetic screw, and a potential energy storage system and/or a resistive force component. The nut is configured to be displaced relative to the elongate body in a first direction in response to manipulation of a magnetic field between the magnetic screw and the nut when the nut is magnetically coupled to the magnetic screw. In embodiments including a potential energy storage system, the potential energy storage system may store potential energy when the nut is displaced in the first direction. In embodiments including a resistive force component, the resistive force component may resist motion of the nut in the first direction by applying a resistive force to the nut at least partially in an opposing second direction.

Abstract: A gyroscope includes a first mass, a second mass, and a drive structure configured to drive each of the first mass and the second mass in a drive mode. The drive structure includes a first portion and a second portion, with the first portion being configured to drive the first mass in a direction along a drive axis and the second portion being configured to drive the second mass in a direction opposite to the first mass along the drive axis. The gyroscope further includes a sense structure configured to sense motion of each of the first mass and the second mass in a sense mode along a direction substantially perpendicular to the drive axis, and a plurality of flexures configured to couple the first portion to the second portion and further configured to decouple the drive mode and the sense mode.

Abstract: A note pen paper system, which includes a roller assembly having an elongated tube member and a knob member. The elongated tube member has a first and second end, where the knob member is coupled to the first end of the elongated tube member. The knob member has a bore extending therethrough where the bore is aligned with a center of the elongated tube member. A pen member is slideably receivable in the knob member and the elongated tube member with a writing tip extends from the bore of the knob member. The pen member is removable from the roller assembly for use. A capholder member is configured to hold the elongated tube member in place in the roller assembly.

Abstract: The present invention provides a board game. The board game includes a display screen. A transparency game sheet is disposed above the display screen, where the transparency game sheet includes a plurality of games. A display holder is configured to hold the transparency game sheet on top of the display screen. A writing instrument is disposed next to the display screen. An arm is affixed to the transparency sheet, where the arm is configured to move the transparency sheet over the display screen.

Abstract: A pen and rolled note paper system for providing note paper and a writing instrument in a single device. The system includes a roller assembly, a pen member, a paper roll, a housing, and a cap. The paper roll is positionable on the roller assembly and is accessible by the user through a slot in the housing. The paper roll is moved forward to be written on and torn off or moved backwards to manually store the written information for the user to review and use later. The pen member is slideably received in the roller assembly which in turn is positioned within the housing. The pen member may be removed from the roller assembly for use, or used while still received by the roller assembly as the user desires. The cap member protects the pen member and the knob member when the system is not in use.
