Abstract: A tool device, such as a lawnmower, or a steerable-wheel assembly therefor may include a frame, a walking element, a drive motor, and a steerable-wheel assembly (SWA). The walking element may be coupled to the frame. The drive motor may selectively power the walking element. The SWA may be attached to the frame apart from the walking element. The SWA may include a caster connector pivotably mounted to the frame to rotate about a pivot axis, a steerable wheel rotatably coupled to the caster connector, a primary drive gear, a primary driven gear, and a secondary driven gear.

The SWA may include a caster connector pivotably mounted to the frame to rotate about a pivot axis, a steerable wheel rotatably coupled to the caster connector, a detectable magnet fixed to the caster connector to pivot therewith about the pivot axis, and an encoder including a magnetic sensor fixed to the frame apart from the caster connector to detect a pivotable position of the detectable magnet.

Abstract: A tool device, such as a lawnmower, or a steerable-wheel assembly therefor may include a frame, a walking element, a drive motor, a steerable-wheel assembly (SWA), and one or more controllers attached to the frame. The walking element may be coupled to the frame. The drive motor may selectively power the walking element. The SWA may be attached to the frame apart from the walking element. The SWA may include a caster connector pivotably mounted to the frame to rotate about a pivot axis, a steerable wheel rotatably coupled to the caster connector, a first sensor configured to detect a pivotable position of the caster connector, and a second sensor configured to detect the set reference point.

Abstract: A disposable system, in some embodiments, includes a multi-channel or multi-chamber test cartridge device configured to operate with a testing system for evaluation of hemostasis in a subject by in vitro evaluation of a test sample from the subject. The disposable system, in some embodiments, is configured to interrogate the test sample to evaluate clot stiffness, strength, or other mechanical properties of the test sample to assess the function of various physiological processes occur during coagulation and/or dissolution of the resulting clot.

Abstract: A method for presenting relationships between data from a thrombosis-hemostasis assay on an unknown sample and data from a purality of assays on known samples, which can be in the form of a topological feature map wherein spatial locations within the map correspond to intrinsic features of the known samples. The position of the unknown sample is superimposed on the positions of the known samples. An alternative presentation is showing the distance of each of a purality of predictor variables from an unknown sample to the mean values of a known population.

Abstract: A method is disclosed for presenting the relationships between data from an assay relating to thrombosis-hemostasis on an unknown sample, and data from a plurality of assays relating to thrombosis-hemostasis from known sample populations including, (a) providing data from at least one time dependent measurement profile for each of a plurality of known blood samples; (b) measuring a respective property over time as to derive at least one time-dependent measurement for an unknown blood sample; (c) transforming data from steps (a) and (b) to a plurality of predicator variables which sufficiently capture the information content of both the time-dependent measurements from the known blood samples and unknown blood sample; (d) presenting the data from said unknown blood sample time-dependent measurement profile relative to the data from said known blood sample time-dependent measurement profiles using the presentation method of either steps (e), (f), and (g), or steps (h) and (i); namely, (e) creating a topological
