Abstract: An example position determining apparatus, includes a power source, position sensors, and a controller. The position sensors are each selectively powered by the power source and configured to provide a respective sensor reading indicating a proximity of a tracked object. The controller is configured to receive respective sensor readings from the position sensors and identify a position sensor that provided an extremum sensor reading. Based on the sensor readings, the controller selectively cause powering of certain position sensors and prevents powering of other position sensors. The position sensor that provided the extremum sensor reading is one of the powered position sensors. A position output based on the sensor readings is also provided.

Abstract: A method and transmission system for amplifying and providing navigation signals. The system comprises a splitter circuit configured to receive a plurality of radio frequency (RF) signals oscillating at at least two different frequencies f1 and f2. The splitter circuit is further configured to split and forward the RF signals having the f1 frequency to a first bandpass filter and the RF signals having the f2 frequency to a second bandpass filter. The system further comprises a first tunable amplifier configured to receive the RF signals from the first bandpass filter. The system further comprises a second tunable amplifier configured to receive the RF signals from the second bandpass filter at substantially the same time as the first tunable amplifier's receipt of the RF signals from the first bandpass filter. The first tunable amplifier is further configured to amplify its RF signals across a first band centered around the frequency f1.

Abstract: In one embodiment, a method includes accessing a calibration model for a camera rig. The method includes accessing multiple observations of an environment captured by the camera rig from multiple poses in the environment. The method includes generating an environmental model including geometry of the environment based on at least the observations, the poses, and the calibration model. The method includes determining, for one or more of the poses, one or more predicted observations of the environment based on the environmental model and the poses. The method includes comparing the predicted observations to the observations corresponding to the poses from which the predicted observations were determined. The method includes revising the calibration model based on the comparison. The method includes revising the environmental model based on at least a set of observations of the environment and the revised calibration model.

Abstract: A computing device is provided, including a processor configured to execute an application-under-test including a plurality of tasks. Each task may be executed in one or more task instances. The processor may determine respective performance data for the one or more task instances of each task. The processor may output, for display on a display, a graphical user interface (GUI) including a statistical representation of the performance data. The processor may receive, at the GUI, a selection of a task executed in a plurality of selected task instances in the application-under-test. The selected task instances may be executed in selected task execution time intervals that are at least partially non-contiguous in time. The processor may generate an aggregated view of the corresponding performance data for the selected task instances aggregated over the selected task execution time intervals. The processor may output the aggregated view for display at the GUI.

Abstract: Methods for rowgroup consolidation with delta accumulation and versioning in distributed systems are performed. The systems provide performant methods of row storage that enable versioned modifications of data while keeping and allowing access to older versions of the data for point-in-time transactions. The accumulation of valid rows, deletes, and modifications is maintained in blobs for rowgroups until a size threshold is reached, at which point the rows are moved into a columnar compressed form. Changes to data and associated metadata are stored locally and globally via appends, maintaining logical consistency. Metadata is stored in footers of files allowing faster access to the metadata and its associated data for transactions and instant rollback via metadata version flipping for aborted transactions, as well as lock-free reads of data.

Abstract: An actuator assembly for actuating an electrical switch housed in sealed electrical enclosure is disclosed. The actuator assembly includes a handle assembly including a handle positioned on an exterior of a cover of the sealed enclosure, a trip bracket positioned within the sealed enclosure and a shaft connecting the handle to the trip bracket. A slider actuator is slidably mounted over an electrical switch positioned within the enclosure and operatively associated with or coupled to a toggle of the electrical switch. The slider actuator has a drive link which is adapted to engage the trip bracket such that rotation of the handle activates the drive link which causes linear movement of the slider actuator to move the electrical switch between on and off positions. The use of the slider actuator allows a higher density of electrical switches to be stacked within the sealed enclosure.

Abstract: A disclosed system, method and computer readable storage medium includes mechanism for controlling cascade price movements in an electronic trading system. Price limits control the prices at which traders can place orders. An upper price limit prevents traders from placing orders above the upper limit and a lower price limit prevents traders from placing orders below the lower limit. The gap between the upper limit and the indicative marked price as well as the gap between lower limit and the indicative market price is controlled so as to cause a breaking effect on very rapidly changing market price.
