Abstract: A method for manufacture of a pressure sensing mat comprising the steps of: (a) preparing two conductive layers, each conductive layer comprising an array of conducting strips mounted upon a substrate arranged in a parallel fashion, wherein the conducting strips of the first conductive layer are oriented perpendicularly in relation to the conducting strips of the second conductive layer; (b) for each conductive layer, connecting each of the conducting strips to a communication line; (c) sandwiching a compressible layer between the two conductive layers; and (d) performing a pressure reading standardization test to the mat.

Abstract: A system and method for the management of data collection from a pressure sensing apparatus. The system allows rapid measurement of pressure exerted upon a surface and may be useful in preventing bed sore development in a bed bound subject.

Abstract: A resting body support, such as a mattress or an encasement for a resting body support, comprising a sensor layer is disclosed which may incorporate a mattress adjustment system. The system may comprise at least one pressure detection mat comprising a plurality of sensors arranged in a matrix and at least one processor configured to monitor a plurality of pressure values detected by each of said sensors; and at least one active mattress comprising a plurality of cells, the cells being controlled by an inflation control unit that is connected to said processor, and operable to individually adjust the level of inflation of said plurality of cells based on said plurality of pressure values.

Abstract: A pressure wound prevention system operable to prompt at least one caregiver to reposition a subject at risk of developing pressure wounds. A pressure detection apparatus comprising a plurality of sensors monitors pressure exerted upon the subject by a surface. A processor is operable to interpret and analyze data from the sensors and a notification mechanism such as a display, an alert, alarm or the like is provided to notify a caregiver when the subject requires repositioning.

Abstract: A joint stabilizing apparatus having an expandable cylindrical housing is inserted into a circular hole drilled at a “loose joint” of a concrete slab that is to be stabilized against relative vertical displacement between adjacent slab sections. The hole is drilled downward into the concrete, centered on the plane of a lateral opening/joint in the concrete slab. The expandable housing comprises two rigid semi-circular housing halves, and the assembly is oriented inside of the circular hole such that the two housing halves are on opposite sides of the centerline of the lateral opening/joint. The housing halves are pushed apart by turning of a threaded bolt inside of the housing. Turning of the bolt causes two bi-laterally symmetric wedge blocks to draw towards each other, and pressing the bearing surfaces of the wedge blocks against inclined surfaces inside of the respective housing halves.

Abstract: A method of resurfacing a road or the like wherein existing surface profile is first measured as a function of distance over the road surface. A desired profile is then identified as a function of measured road profile by simulating travel of a vehicle over the road surface and observing the quality of vehicle ride and/or pavement dynamic load while the spatial wavelength characteristics of measured profile are progressively attenuated. When ride quality and/or dynamic load of desired preselected standard is obtained, a resurface control signal is obtained as a conjoint function of distance along the road surface and the difference between measured profile and spatially attenuated profile. Road resurfacing equipment is also disclosed for selective removal of pavement surface material or selective deposition of paving material as a function of the control signal so obtained to achieve the desired resurfaced road profile.
