Abstract: Identification of content gaps based on relative user-selection rates between multiple discrete content sources. A system analyzes search log activity to determine whether users that are conducting particular types of search activities are ultimately selecting and relying upon content resources from a predefined content source of interest or, alternatively, whether such users are unsatisfied with the predefined content source of interest and are instead relying upon other third-party content sources. This particular type of analysis provides valuable insights into whether content gaps exist within the predefined content source of interest.

Abstract: A system for motion analysis of a subject includes two or more sensor units that are attachable at respective attachment points of the subject to detect motion of the attachment points relative to each other, each sensor unit including a time-of-flight (TOF) ranging sensor in communication with at least one processor. The at least one processor is configured to: cause the sensor units to execute a two-way ranging protocol at a succession of times, said two-way ranging protocol including transmission of one or more signals from, and reception of one or more signals at, said TOF ranging sensors, to determine TOF distance data indicative of one or more respective distances between the sensor units at respective times; and determine, from at least the TOF distance data, one or more motion metrics.

Abstract: A vault lowering aid comprising a housing; an elongated member; a drive shaft; a drive sprocket disposed within the housing and engaged with the draft shaft, such that a rotation of the draft shaft causes a rotation of the drive sprocket; at least one driven sprocket disposed within the housing and engaged with the drive sprocket via a chain, wherein the chain enables the rotation of the drive sprocket to cause a rotation of the driven sprocket; a driven shaft, wherein the driven shaft is engaged with the driven sprocket, such that the rotation of the driven sprocket causes the rotation of the driven shaft, and wherein the driven shaft is configured to engage a vault lowering device geared box; and at least one guide mechanism configured to secure the vault lowering aid on the geared box.

Abstract: A method and apparatus for collecting and distributing information to and from a computing element that is quickly scalable at the installation to varying types and numbers of signals. Standard sized modules containing a generalized set of; computation, discrete I/O, analog I/O, serial I/O, adaptable I/O, etc. or any combination thereof, provide the building blocks that can be attached to each other to provide the desired combination of functions. These modular components are mated to each other through a simple serial interface providing the inter-module communication interface and local power requirements. The modules are quickly stacked together and snapped in place in a manner supporting severe environmental conditions.
