One of the methods includes obtaining data specifying a training example, including a first image of a scene in an environment captured at a first time point and a second image of the scene in the environment captured at a second time point. For each of a plurality of lidar points, a respective second corresponding pixel in the second image is obtained and a respective velocity estimate for the lidar point at the second time point is obtained. A respective first corresponding pixel in the first image is determined using the velocity estimate for the lidar point.

Publication number: 20220117745Abstract: A self-broaching, neck-preserving hip stem includes a set of rasp teeth on a distal-lateral portion of the stem to allow the stem to be impacted into a femur without the use of surgical broaches. The rasp teeth are disposed on a relief surface. The stem includes a length, radius of curvature, and a dual-taper in the anterior-posterior and distal-lateral directions which allow the neck to self-broach and seat itself proximal to the conventional resection level to preserve greater bone stock in the femur.Type: ApplicationFiled: October 12, 2021Publication date: April 21, 2022Applicants: Howmedica Osteonics Corp., Howmedica Osteonics Corp.Inventors: Shammodip Roy, Daniel Rudolf Scholl, Tyler Saunders

Patent number: 10908258Abstract: Method and system of calibrating a sensor system which comprises sensor A and sensor B. Sensor A has a transmitter TXA for emitting a signal STXA and a receiver RXA for receiving a signal SRXA, wherein RXA and TXA operate independently in a radar mode of sensor A. Sensor B has a transmitter TXB, a receiver RXB, and a unit D, which is used to connect TXB to RXB in a transponder mode of sensor B, with the result that a signal SRXB received by RXB is emitted again by TXB as a signal STXB. A gain Gcon,B between signal SRXB and signal STXB is predefined. In a radar mode of sensor B, TXB is not connected to RXB, with the result that TXB and RXB operate independently. Emitted signals may be radar, light, or acoustic signals. The method and system can calibrate radar systems, lidar systems, or sonar systems.Type: GrantFiled: January 31, 2017Date of Patent: February 2, 2021Assignee: Deutsches Zentrum für Luft- und Raumfahrt e.

Publication number: 20190018105Abstract: The invention relates to a method for calibrating an active sensor system which comprises at least one active sensor A and one active sensor B. The term “active” indicates that the sensors A and B actively emit signals. The sensor A has a transmitter TXA for emitting a signal STXA and a receiver RXA for receiving a signal S RXA, wherein the receiver RX A and the transmitter TXA operate independently of one another to the greatest possible extent in a radar mode of the sensor A. The sensor B has a transmitter TXB, a receiver RXB, and a unit D, which is used to connect the transmitter TXB to the receiver RXB in a transponder mode of the sensor B, with the result that a signal SRXB received by the receiver RXB is emitted again by the transmitter TXB as a signal STXB. A gain Gcon,B between the received signal SRXB and the signal STXB which is emitted again is predefined in this case.Type: ApplicationFiled: January 31, 2017Publication date: January 17, 2019Applicant: Deutsches Zentrum für Luft- und Raumfahrt e.V.Inventors: Jens REIMANN, Björn DÖRING, Marco SCHWERDT, Daniel RUDOLF, Sebastian RAAB

Patent number: 6543470Abstract: Traps particularly intended for carrying condensate from air conditioner drip trays towards a drainage system are constructed from a single turn of a flexible thermoplastic pipe; each unit being preformed when in a heat-softened state into a shape of a one-turn coil resembling the twist in a pig's tail, or the Greek “alpha” (&agr;) symbol. Traps are made of a transparent flexible durable thermoplastics material, such as polyvinyl chloride, and internal contents may be inspected through the trap wall. Being flexible, the traps can reliably connect mis-aligned conduits. Being flexible, the traps can serve as reliable connectors between conduits where relative movement is a problem such as where vibration or earthquakes occur.Type: GrantFiled: May 22, 2001Date of Patent: April 8, 2003Inventor: Daniel Rudolf Mans
