Abstract: In a system for determining in-seat behavior of a user, a sensor mat is placed on a location of the seat. The sensor mat includes a plurality of sensors that are distributed anthropometrically so as to be placed below predetermined anatomical sites of a typical user. At least one training episode in which the user assumes at least one predetermined posture for a predetermined amount of time is executed. Training data from each of the plurality of sensors is recorded and sensor parameters are adjusted based on the training data. After the training episode, use data is sensed from the plurality of sensors during normal use of the seat by the user. The in-seat behavior of the user is characterized based on the use data which results in the generation of characterization data. At least one predetermined action is taken based on the characterization data.

Abstract: The various embodiments of the present invention relate generally to the analysis of the mechanical properties of materials. More particularly, the various embodiments of the present invention relates to systems and methods of deriving the static and dynamic mechanical properties of deformative materials, for example, but not limited to, biological surfaces. The systems and methods of the present invention can be used to derive and evaluate the mechanical properties of many biological surfaces and subsurfaces, including but not limited to the skin.

Abstract: The present invention discloses systems and methods for the measurement of surfaces. More particularly, the present invention discloses a portable, hand-held, non-contact surface measuring system comprising an image capturing element, at least four projectable reference elements positioned parallel to one another at known locations around the image capturing element, a processing unit, and a user interface. The present invention further discloses a method for the non-contact surface measurement comprising projecting at least four references onto a target surface, capturing an image of the targeted surface and the projected references with the image transferring device, transferring the image to a processing unit, processing the image using triangulation-based computer vision techniques to correct for skew and to obtain surface measurement data, transferring the data to the user interface, modifying the data with the user interface.
