Abstract:
The invention relates to a device which is used to film, record and reproduce video images in real time with a three dimensional appearance, using a video camera and a sonar system in order to obtain the depth information. According to the invention, an electronic system divides up the original image filmed in BGR format and each image is modified in accordance with the depth register (or programming) in order to form new images. Each image corresponds to a determined distance level. The result is displayed on a monitor comprising various independent transparent LCD (liquid crystal display) screens which are aligned one after the other. By displaying the images simultaneously, a single image is formed for the spectator, said image creating an appearance of volume and three-dimensional perception similar to low relief. The depth, video and sound signals are transmitted directly for reproduction purposes and to the magnetic tape recording system for storage purposes, using three magnetic tape heads.
Abstract:
An ultrasonic sensor is described, in which a time curve for the sensitivity is specified via threshold values which are assigned to individual interpolation points. The position in time of the interpolation points for the ultrasonic sensor is variable.
Abstract:
An operator-specifying apparatus is combined with an on-board device such as a navigation device mounted on an automotive vehicle. An ultrasonic sensor device is mounted on a frame of a display panel of the navigation device. A hand of a person who is manipulating the navigation device, a driver or an assistant, is detected by the ultrasonic sensor device. If it is determined that the driver is manipulating (or about to manipulate) the navigation device when the vehicle is being driven, manipulation of the navigation device is prohibited to secure safety in driving. On the other hand, if it is found out the assistant is operating the navigation device, such prohibition is canceled to effectively use the navigation device.
Abstract:
The present invention relates to a method for determining the height of objects disposed on a conveying device, in which an ultrasonic sensor positioned in a specific relationship to the conveying device repetitively transmits ultrasonic pulses directed toward the conveying device and any objects disposed thereon to be detected, wherein the ultrasonic pulses are then reflected from a surface of the conveying device or from surfaces of the objects to be detected and are detected by the ultrasonic sensor, wherein from the moments of transmission and moments of detection of the ultrasonic pulses, delay times of the ultrasonic pulses are determined and the height of an object surface relative to the surface of the conveying device is determined from the delay times of the ultrasonic pulses reflected from a surface of an object. The method is characterized in that the delay time of the ultrasonic pulses reflected from the surface of the conveying device is stored as a reference value, that when there is an increase in the measured delay time from a lower to a higher value, the higher value is stored and used as a new reference value, that when there is a decrease in the measured delay time from a higher to a lower value, the lower value is interpreted as the delay time value of ultrasonic pulses reflected from an object surface, and that the height of the object surface relative to the surface of the conveying device is determined from a difference between the most recently stored reference value and a delay time value relevant to an object surface. The invention also relates to an ultrasonic sensor.
Abstract:
A reflector includes a first end surface, an opposing second end surface and a plurality of reflector surfaces. A first reflector surface extends from adjacent the first end surface toward the second end surface. A second reflector surface extends from adjacent the first reflector surface toward the second end surface. One or more of the plurality of reflector surfaces can include a plurality of facets or reflector zones. A gas spring assembly and suspension system using the reflector is also disclosed.

Abstract:
An embodiment of a method for conducting a bathymetric survey across a seismic spread includes the steps of emitting a signal from a pinger positioned within the seismic spread, measuring the arrival time of a bottom reflection of the signal at a receiver positioned within the seismic spread, measuring the arrival time of a direct arrival of the signal at the receiver, and determining the water depth utilizing the measured arrival times of the signal.
Abstract:
The present invention provides a method and apparatus for capturing an image of a persons head, or other object, positioned in front of a camera and accurately scaling the head based on the distance of the head from the camera. A sonar system is used determine the distance of the object to the camera. The sonar system can include a first sonar device which is operated to measure the distance of the object to a predetermined point and a second sonar device which is used to measure the distance of the camera to the predetermined point. A calculation of the distance from the object to the camera is based upon the sonar measurements. The image created by the camera can be scaled according to the distance of the object to the camera as determined with the sonar. An image created by the camera can be displayed on a screen of a computer associated with the imaging system. Software on the computer can transpose an image of an eyeglass frame over the image of a face, wherein the image of the face was captured by the camera. Measurements relating to proper sizing of an eyeglass or other corrective lens can be performed on the computer screen. Other observations and image manipulations can also be made including skin tone, facial features, head shape and size, application of cosmetics, proposed surgery, and many other uses.
Abstract:
A stack control mechanism comprising a mechanism for feeding and accumulating sheets to an accumulating area. A control mechanism for controlling the feeding of the sheets to the accumulating area which includes emitting an impulse or vibration onto that stack ad receiving vibrations or impulses which are reflected from the stack. The feeding mechanism is responsive to the controlling mechanism to adjust to rate of feeding of sheets to the accumulating area.
Abstract:
