Publication number: 20210199765Abstract: The device of the present invention is an electro-optical distance meter that operates by reflecting a beam of light off of a target or object for which the distance from the meter is desired to be known. Unlike conventional optical time-of-flight meters, the beam of light in this case is a continuous sine signal that forms a functional part, including the path thereof, of a positive feedback line that feeds a high-gain amplifier that thus becomes an oscillator having a frequency proportional to the distance at which the object is located, the frequency-distance ratio being logarithmic. The circuit is essentially characterized in that, despite using light to evaluate distance, it does not require ultra-high-speed circuits but only conventional industrial-level, or even commercial-level, circuits, providing a low-cost solution to the need to estimate distances from a short range in a compact form.Type: ApplicationFiled: March 12, 2018Publication date: July 1, 2021Inventor: Ernst Albert REMBERG BUENO

Patent number: 11014495Abstract: The invention relates to a system that provides protection to a vehicle against impacts when the vehicle is parked. The system consists of using the elements with which some vehicles are manufactured to design a system that provides protection to the vehicle when parked. In a first embodiment, the system uses as proximity sensors the ultrasound transducers with which certain vehicles are equipped. Subsequently, by mathematically manipulating this data in the elements designed for this purpose in the central computer, the system calculates the speed and acceleration of vehicles approaching the parked vehicle, issuing a visible and audible alarm to prevent a collision.Type: GrantFiled: March 14, 2017Date of Patent: May 25, 2021Inventor: Ernst Albert Remberg Bueno

Patent number: 4564993Abstract: In a screw drive, in particular a ball screw drive, a double nut, formed of a pair of individual nuts, is tightened on a threaded spindle and the individual nuts are secured together against relative rotation by a locking member. The locking member is secured within a radially extending recess formed in and bridging the individual nuts. The locking member can be inserted with a certain amount of play into the recess or borehole and then secured within the recess by a cement or similar material so that it cannot be displaced. Various types of locking members can be used, such as locking bolts or threaded bolts. When the locking member is connected into the recess or ball it prevents any rotation of the individual nuts relative to one another.Type: GrantFiled: March 1, 1983Date of Patent: January 21, 1986Assignee: Deutsche Star Kugelhalter GmbHInventors: Gunter Blaurock, Ernst Albert, Werner Blaurock, Benno Peichl, Klaus Reichert, Hans-Georg Stender, Rudolf Schlereth

Patent number: 4474073Abstract: A spindle drive assembly includes a spindle and a spindle nut defining a helical ball duct therebetween through which a plurality of recirculating balls may pass during relative rotation between the spindle and the spindle nut to effect transmission of axial forces therebetween. A helical internal ball guide formed on the spindle nut and defining one side of the helical ball duct is formed with at least one compensating slot which extends to the walls of the helical internal guide in order to effect circumferential division of the spindle nut to enable the spindle nut to radially adapt to compression forces applied by the clamping device extending about the spindle nut to provide radial compression maintaining the balls in operative load-bearing engagement within the helical duct. The slot is formed with a width taken circumferentially of the spindle nut which is not greater than 15% of the diameter of the recirculating balls, and preferably not greater than 10% of the ball diameter.Type: GrantFiled: November 18, 1980Date of Patent: October 2, 1984Assignee: Deutsche Star Kugelhalter GmbHInventors: Gunter Blaurock, Ernst Albert

Patent number: 4357838Abstract: In a ball screw and nut drive device, a helical ball spindle or channel is formed in the inner surface of a nut body and the outer surface of a screw. Balls are circulated through the helical ball channel being returned from one end to the other of the channel by deflecting channels and a return channel. Each deflecting channel is formed in part by a deflecting member fitted into a recess formed in the inner surface of the nut body. The deflecting member includes a projection for lifting balls out of the helical ball channel into the deflecting channel. The deflecting channel has a rectilinear part which can receive balls from the helical ball channel and a curved part connecting the rectilinear part with the return channel. The deflecting channel in the deflecting member is open along its length and the balls passing therethrough contact a wall in the recess formed in the nut body.Type: GrantFiled: April 3, 1980Date of Patent: November 9, 1982Assignee: Deutsche Star Kugelhalter GmbHInventors: Gunther Blaurock, Ernst Albert, Horst Altrock

Patent number: 4274297Abstract: A spindle and a spindle nut having external and internal threads, respectively, formed thereon and circulating balls operatively engaged between said threads operating to effect transmission of forces axially thereof when the spindle and spindle nut are rotated relative to each other. The balls are circulated through ball ducts formed by the threads and by the circulating means which return the balls from ball duct outlets of the threads to ball duct inlets thereof. Compensating means for enabling adjustment of the operating pressure between the spindle and the spindle nut by adjusting the diameter of the spindle nut enable compensation of the degree of play which is developed between the balls and the ball ducts through which the balls are circulated. In one aspect of the invention, the spindle nut is formed with a longitudinal slit thereby enabling adjustment of the diameter of the spindle nut and of the pressure by which it is engaged about the spindle.Type: GrantFiled: January 25, 1979Date of Patent: June 23, 1981Assignee: Deutsche Star Kugelhalter GmbHInventors: Gunter Blurock, Ernst Albert
