Abstract: The present disclosure generally relates to methods and systems for generating a void profile for user void events. The method includes receiving by a processing element a plurality of outputs from a fluid level sensor corresponding to a plurality of levels of fluid flowing through a voiding device during a flow event; determining by the processing element a beginning and an end time of the fluid flow into the voiding device during the flow event; analyzing the plurality of outputs of the fluid level sensor over a time interval defined by the beginning and end time of the fluid flow to determine at least one of a fluid flow rate data and an accumulated volume data for the fluid flowing through the voiding device; and storing the fluid flow rate data and the accumulated flow volume data in a memory.

Abstract: Uroflowmeters and methods for processing data generated therefrom are disclosed. In one aspect, the uroflowmeter is a handheld device. The uroflowmeter includes a handle, a flow chamber coupled to the handle, and a sensor associated with the flow chamber that detects a parameter of urine received in the flow chamber. The uroflowmeter may include both reusable and disposable components. As a uroflowmeter it can identify and record data corresponding to the rate of flow over the measured duration of a void of urine, but may also timestamp the voiding act and communicate the data to an external data collection center for additional analysis and incorporation into a comprehensive voiding report or voiding diary.

Abstract: Systems and methods may be used to select a drill bit design for an earth-boring rotary drill bit for use in a particular drilling application. The systems may include a computer server, and a remote device configured to communicate with the computer server through a network. The computer server may include a database including information relating to normalized scores for a plurality of drill bit responses for a plurality of differing drill bit designs. The computer server may receive information from the at least one remote device, to select one or more potential drill bit designs from the at least one database based on the information, and to transmit information relating to the selected one or more potential drill bit designs to the remote device. Such systems may be used in methods of selecting drill bit designs for earth-boring rotary drill bits for use in respective drilling applications.

Abstract: An expandable reamer apparatus and methods for reaming a borehole, wherein a laterally movable blade carried by a tubular body may be selectively positioned at an inward position and an expanded position. The laterally movable blade, held inwardly by blade-biasing elements, may be forced outwardly by drilling fluid selectively allowed to communicate therewith by way of an actuation sleeve disposed within the tubular body. Alternatively, a separation element may transmit force or pressure from the drilling fluid to the movable blade. Further, a chamber in communication with the movable blade may be pressurized by way of a downhole turbine or pump. A ridged seal wiper, compensator, movable bearing pad, fixed bearing pad preceding the movable blade, or adjustable spacer element to alter expanded blade position may be included within the expandable reamer. In addition, a drilling fluid pressure response indicating an operational characteristic of the expandable reamer may be generated.
