Granted: 2017-12-12
Abstract: A method and apparatus for correcting alignment error between a tool end effector and a master actuator in a master-slave robotic system is disclosed where the end effector is controlled by the master actuator transmitting control signals. The method involves receiving master orientation signals, generating end effector orientation signals, producing control signals based on the end effector orientation signals, and receiving an enablement signal for enabling transmission of control signals to the slave. When transitioning from the not active to active state, the master actuator and end effector orientation signals are saved to create previous-saved values. The method also involves detecting a difference between the master actuator and end effector orientation signals representing a physical alignment difference and adjusting saved slave base orientation signals to have the same values as the saved master base orientation signals so that the control signals cause the tool to satisfy an alignment criterion.

Abstract: Systems, methods, and devices relating to the determination of a volume of liquid in a container. A pressure sensor is located at a bottom of the container. The pressure sensor senses the pressure exerted on it by the liquid in the container. This pressure is communicated with a data processing device. The data processing device determines the volume of the liquid in the container based on the sensed pressure. This may be done by reference to a look up table containing pressure values and their corresponding volumes. Similarly, this may be done by calculating the volume of the liquid based on the dimensions of the container, the physical qualities of the liquid, and the sensed pressure. The volume of the liquid in the container is then transmitted from the data processing device to a user interface device for presentation to a user.

Abstract: Particular embodiments use a multi-view coding (MVC) extension to provide second-screen content along with the first-screen content. In one embodiment, a head-end multiplexes the first-screen content with the second-screen content into a single content stream. The second-screen content is added to the video stream according to the MVC extension requirements. At the user end, such as at a gateway, instead of sending the first-screen content and second-screen content to the first-screen device, the gateway de-multiplexes the first-screen content and the second-screen content. The gateway can then send the first-screen content to the first-screen device while caching the second-screen content. When the gateway determines that the second-screen content should be displayed on the second-screen device, the gateway can send the second-screen content to the second-screen device for display on the second-screen of the second-screen device.

Title: Lidar measuring device for determining the speed of particles in a measuring volume
Inventor: PETERS GERHARD
IPC: G01S17/95
Filed: 2018-03-20
Granted: 2022-03-15
Abstract: The invention relates to a LIDAR measuring device and a method for determining the speed of particles in a measurement volume with a narrow-band continuous wave laser light source (1), which emits light which is coupled into a measuring branch (3) and a reference branch (4), wherein the light coupled into the measuring branch (3) is at least partially emitted by a transmitting device in the direction of the measuring volume in such a way that the emitted light is at least partially scattered and/or reflected by the particles in the measuring volume. A part of the scattered and/or reflected light is then received by a receiver device and is coherently superimposed with the light leaving the reference branch (4), and the resulting light beam is directed onto a detector (6) to generate a detector signal characteristic for the resulting light beam. Finally, the speed of the particles in the measuring volume is determined in an evaluation unit (11) by taking into account the detector signal. The technical solution described is characterized in that the frequency of the light emitted by the laser light source (1) is varied by a control device (13) and the evaluation unit (11) is configured to determine the speed of the particles in at least one measuring area of the measuring volume on the basis of a spectral analysis of the detector signal by taking into account the predefined frequency modulation.
