  • Publication number: 20250068835
    Abstract: A data processing system implements receiving a first input in a spreadsheet in a spreadsheet application, detecting an indication that the first input includes first executable program code, analyzing the first executable program code to identify first references to one or more first elements of the spreadsheet in the first executable program code, requesting spreadsheet data associated with the one or more first elements of the spreadsheet from the spreadsheet application, receiving the spreadsheet data from the spreadsheet application; executing the first executable program code using the spreadsheet data referenced in the first executable program code to obtain a first program code result and causing the spreadsheet application to display the first program code result in the spreadsheet application.

    Abstract: The subject matter of this specification relates to a light detection and ranging (LiDAR) system. In at least one implementation, the LiDAR system comprises a first signal source; a second signal source; a combiner to generate a hybrid transmission signal from signals generated by the first signal source and the second signal source; a first photodetector to measure a first component of a reflection signal related to range of a target; and a second photodetector to measure a second component of the reflection signal related to velocity of the target, wherein the system is configured to derive the range and velocity of the target from the first component and the second component, respectively.

  • Publication number: 20220187468
    Abstract: The subject matter of this specification can be implemented in, among other things, systems and methods that enable lidar channel multiplexing using optical locking of separate lasers while simultaneously imparting different frequency offsets to beams output by different lasers. As a result, received beams reflected from various objects, which are present in an outside environment, can have Doppler-shifted frequencies that do not overlap, facilitating concurrent identification of distances to and velocities of multiple objects.

  • Publication number: 20200239208
    Abstract: The present invention relates to a tamper evident produce container having two front corners. The produce container includes a receptacle, a lid and a pair of frangible tabs. The receptacle has a mouth circumscribed by a first flange. The lid is associated with the receptacle to close off the mouth. The lid has a second flange. Each frangible tab is joined to either one of the first or second flange at or in close proximity to one of the two front corners by an area or line of weakness. Each frangible tab includes a first locking formation which is adapted to interlock with a second locking formation provided on or in the other of the first or second flange when the lid is positioned on the receptacle to close off the mouth.

  • Publication number: 20200122918
    Abstract: A produce container including a receptacle and a lid. A mouth is circumscribed by a rim with a first bearing surface substantially parallel to a receptacle base. A first outer wall portion of the rim is folded back on and substantially perpendicular to the base. One or more first locking formations is carried on the first outer wall portion. The lid can close off the mouth and is circumscribed by a skirt with a second bearing surface substantially parallel to the base when the lid is closed. The skirt has a first inner wall portion substantially perpendicular to the base when the lid is closed. The skirt has one or more second locking formations carried on the first inner wall portion of the lid. Each second locking formation is complementary to a first locking formation. The rim includes one or more chamfered portions above the first locking formation inclined to the first bearing surface and the first outer wall portion.
