Abstract: An exercise management and reporting system includes a weightlifting rack having a plurality of vertical members. Each of the vertical members include bar support brackets for receiving a barbell and weighted plate combination. Tracking sensors are positioned along the vertical members to track the movement of the barbell during an exercise. A control unit having a memory and wireless transmitter are provided along the rack. Weight sensors are positioned within each of the bar support brackets, and a wireless accelerometer is positioned along the barbell. The system also includes an exercise management application that receives the exercise data from the control unit and recommends and adjusts exercise workouts based on the received exercise data for each system user.

Abstract: A wand apparatus for controlling a pressure washing system and an associated method for controlling a pressure washing system is provided. The wand apparatus may include a first wand portion and a second wand portion. The wand apparatus may further include a chemical control assembly that includes a housing and a chemical control element. The housing defines an outlet aperture, an inlet aperture, and a chemical control aperture. The chemical control aperture is configured to operably engage the chemical control element. The outlet aperture is configured to operably engage the first wand portion, and the inlet aperture is configured to operably engage the second wand portion. Further, operable engagement of the chemical control element may provide for switching the wand apparatus between a chemical spray configuration and a wash spray configuration.

Abstract: An inkjet finger manifold is provided that includes a longitudinal manifold chamber with an entrance at a first end adjacent to a first longitudinal side. A purge vent is located at a second end on a second longitudinal side opposite the first longitudinal side. A first ramp is located at the first end sloping away from the entrance toward the second longitudinal side. A second ramp is located near the second end and slopes from the second longitudinal side toward the second end and the first longitudinal side to alter the laminar flow of the ink through the longitudinal manifold.

Abstract: A container including a first tank for receiving a liquid, a second tank that is selectively pressurizable, a check valve for permitting fluid flow from the first tank to the second tank, and a manifold structure having a first port fluidically coupled to the first tank and a second port fluidically coupled to the second tank.

Abstract: A drop emitting device including an array of finger manifolds, each finger manifold having longitudinally separated first and second ends, wherein the first end comprises a fluid receiving end; a plurality of drop generators, each fluidically coupled to one of the finger manifolds; and a respective vent structure located at the respective second end of each of the finger manifolds for supporting a plurality of meniscuses.

Abstract: A drop emitting device including a first linear array of columnar arrays of first nozzle pairs and a second linear array of columnar arrays of second nozzle pairs, wherein the first linear array and the second linear array extend along an X-axis, and wherein the second linear array is adjacent the first linear array such that each first nozzle pair has an associated second nozzle pair displaced therefrom along a Y-axis that is orthogonal to the X-axis. The columnar arrays of first nozzle pairs and the columnar arrays of second nozzle pairs extend obliquely to the X-axis.
