Abstract: Methods and systems for duplicating holograms, including illuminating a master hologram using a first portion of a beam to generate a data beam, recording a copy hologram using a second portion of the beam and the data beam, where the master hologram and the copy hologram are arranged such that the second portion of the beam avoids the master hologram.

Abstract: Hologram recording devices and techniques can be employed to produce wide field-of-view holograms. A lens can be used to couple an object beam into a holographic recording material without substantially changing the angle of incidence of the object beam. When displayed, images from holograms recorded using this technique can have a field-of-view greater than that of the object beam. One or more aspheric reflective surfaces can be used to couple an object beam into a holographic recording material at relatively steep angles.

Abstract: An emergency opening device for an overhead locker with a housing and a lowerable shell includes a connecting element which is connectable to a retention system operatively coupling the housing to the lowerable shell. The emergency opening device also includes a locking device adapted to move from a locked position in which the locking device is coupled with the connecting element to an unlocked position in which the locking device is uncoupled from the connecting element to release the lowerable shell from the retention system.

Abstract: Hologram production devices can include holographic recording material deposition systems to deposit holographic recording material as needed by the hologram production device. Various nozzles, ink jets, and similar devices can be used to deposit one or more components of the holographic recording material on to an appropriate substrate. If needed, the material is pre-processed to, for example, provide material stability for the holographic recording material. Once holograms are recorded in the holographic recording material, the material can be post-processed as desired.

Abstract: In a method for determining at least one, preferably however several driver-independent interventions in a vehicle system, a risk calculator is used, whose input is supplied with predetermined vehicle data, ambience data, current vehicle and driver data, occupant data or data of persons outside the vehicle, or similar data. The risk calculator issues an evaluation of the risk situation of the vehicle and its occupants or the persons outside the vehicle based on said data and, in accordance with the evaluation and optional additional criteria or weightings, outputs driving signals controlling actuators that modify or trigger the driving behavior of the vehicle and/or the occupant protection system and/or protection means for other traffic participants (pedestrians, cyclists, etc.) in such a way that maximum protection is obtained for the persons and the vehicle according to a priority control.

Abstract: Hologram production techniques can combine source data representing realistic information describing an environment with source data providing representational information describing a feature of the environment and/or some object interacting with the environment. The combined data is used to produce holograms, and particularly holographic stereograms including features that enhance the visualization of the environment depicted in hologram. A haptic interface can be used in conjunction with such holograms to further aid use of the hologram, and to provide an interface to secondary information provided by a computer and related to the images depicted in the hologram.

Abstract: Pre-sensitization techniques can be used in conjunction with holographic recording materials to allow high quality holographic stereograms to be recorded in those holographic recording materials using pulsed lasers. Additional hologram production system hardware and software designs for use with pulsed lasers are disclosed.

Abstract: User input is facilitated through gestural inputs with displayed two and three-dimensional objects using a holographic device and film that displays a static, digitally generated, three-dimensional, autostereoscopic, full-parallax, real image and a digital projector that displays dynamic images. A system includes computer-detectable tags mounted on a user-wearable glove, and on a base plate that holds the holographic device. The system determines the locations of the tags, and calculates a location of a feature of the image based on the locations of the tags. The system also determines the location, pose, and gestural motion of the input device based on the location of the tags. The system further calculates a distance and direction between the input device and the feature of the image.

Abstract: A dynamic three-dimensional image can be modified in response to poses or gestures, such as hand gestures, from a user. In one implementation, the gestures are made by a user who selects objects in the three-dimensional image. The gestures can include indications such as pointing at a displayed object, for example, or placing a hand into the volume of space occupied by the three-dimensional image to grab one or more of the displayed objects. In response to the gestures, the three-dimensional display is partially or completely redrawn, for example by an alteration or repositioning of the selected objects. In one implementation, a system simulates the dragging of a displayed three-dimensional object by a user who grabs and moves that object.

A system intervenes in an appropriate manner into the motional behavior of the vehicle, influencing the latter in such a way that the vehicle can be brought into a safe position without the cooperation of the driver (autonomously).

One or more emissive display devices are coupled to one or more appropriate computing devices. These computing devices control delivery of autostereoscopic image data to the emissive display devices. A lens array coupled to the emissive display devices, e.g., directly or through some light delivery device, provides appropriate conditioning of the autostereoscopic image data so that users can view dynamic autostereoscopic images.
