Abstract: A web based collaborative music playlist application that the primary user, the Host, may use to generate a unique code to create a virtual room. This code may be shared with others who may then join the room as guests. Within the room, the guests may be able to request songs and the application may then queue the requests into a playlist, which may be edited by the host in real time. The host's device serves as the single point of communication between the room and a music service.

Abstract: An electric motor assembly, mud pulser and a method for transmitting data. The electric motor assembly includes an electric motor having a rotor and a stator that includes one or more windings; one or more sensors on the stator and configured to determine an angular position of the rotor; and a motor control circuitry configured to control a commutation of the electric motor based on signals received from the one or more sensors. The motor control circuitry is configured to determine a total angular rotation of the rotor based on a back emf voltage of the one or more windings and independent of the signals from the one or more sensors.

Abstract: The present invention provides isolated nucleic acids containing functional polynucleotide sequences from the upstream region of the RANKL gene useful in conferring transcriptional responsiveness (e.g., vitamin D3 receptor complex responsiveness) on associated promoters and methods of using same to identify chemical entities capable of affecting transcriptional activity of the RANKL gene.

Abstract: An integrated system for tracking assets (tools and materials) and personnel associated with a work site. Personnel are equipped with tracking devices having at least geolocation capability. Assets are tagged with RFID tags, which are interrogated at portals, by mobile scanners, or by personnel tracking devices having RFID reading capability. The tag readers and tracking devices are all in communication with a common “information backbone” and all data is delivered to, and processed by, a common command and control subsystem.

Abstract: An instrument for testing fluid characteristics has a vial and a housing. The vial defines a chamber for receiving a sample of the fluid and has a cap for sealing the fluid therein. The housing defines a recess for receiving the vial. Multiple light emitting diodes and photovoltaic detectors are arranged on multiple meridional planes within the housing. The meridional planes each intersect approximately at a central axis of the chamber when the vial is placed within the recess. Modulation of the light emitting diodes and tuned processing electronics allow for simultaneous evaluation of sample characteristics such as spectral transmittance, turbidity and fluorescence. The user selects particular tests via a keypad and a display indicates the results of the chosen analysis.
