Extracorporeal blood treatment apparatus with reservoir status lights and methods of monitoring reservoir status using the same are described. The extracorporeal blood treatment apparatus include a plurality of reservoir scales (30), each of which is configured to weigh a reservoir (32) used in connection with the extracorporeal blood treatment apparatus. A plurality of reservoir status lights (40) are provided, with one or more of the reservoir status lights (40) associated with one of the reservoir scales (30). The one or more reservoir status lights (40) associated with one of the reservoir scales (30) emit light from a location that is closer to their associated reservoir scale than to any other reservoir scale of the extracorporeal blood treatment apparatus.

A weighing system includes a support, a load cell mounted to the support, and a part platform suspended from the load cell to receive a part to be weighed. The load cell is operable to generate thousands of weight values for the part per second over a period of less than twenty seconds. The load cell is operable to output a weight of the part by averaging the weight values over the period of less than twenty seconds. A method of weighing the part suspended from the load cell is also disclosed.

A load suspension and weighing system for a removable reservoir unit of a portable dialysis machine includes a centrally located flexure assembly. The flexure assembly includes magnets and a number of flexure rings which allow for movement of the magnets about a fixed circuit board. Sensors in the circuit board sense changes in the magnetic field as the magnets move in relation to the circuit board. The magnetic field changes produce a voltage output which is used by a processor to generate weight calculations. The top of the flexure assembly is attached to the interior of the dialysis machine. The entirety of the reservoir unit is suspended by a first internal frame that is attached to the bottom of the flexure assembly. Having a single flexure assembly positioned above the reservoir unit provides more accurate weight measurements while also preventing damage to the assembly from water spillage.

A non-transitory computer-readable medium includes instructions that when executed by a processor cause the processor to perform a method for assessing quality of tasks performed by persons in retail stores. The method may include receiving an indication that a person completed a task corresponding to at least one shelf in a retail store. The method may also include receiving at least one image of the at least one shelf, the at least one image being captured using an image sensor after the completion of the task. The method may further include analyzing the at least one image to determine at least one property associated with performing the task. The method may further also using the at least one property to determine a reward for performing the task.

A method for determining a tyre normal force range (F.sub.z,min, F.sub.z,max) of a tyre force (F.sub.z) acting on a vehicle (100), the method comprising; obtaining (S1) suspension data (310) associated with a suspension system of the vehicle (100); obtaining (S2) inertial measurement unit, IMU, data (320) associated with the vehicle (100); estimating (S3), by a suspension-based estimator (330) a first tyre normal force range (F.sub.z1,min, F.sub.z1,max) based on the suspension data (310); estimating (S4), by an inertial force-based estimator (340), a second tyre normal force range (F.sub.z2,min, F.sub.z2,max)based on the IMU data (320); and determining (S5) the tyre normal force range (F.sub.z,min, F.sub.z,max) based on the first tyre normal force range (F.sub.z1,min, F.sub.z2max) and on the second tyre normal force range (F.sub.z2,min, F.sub.z2,max).
