48 results about "Induced movement" patented technology

Induced movement in a patient is detected and correlated with a TMS stimulating pulse so as to determine the patient's motor threshold stimulation level. Direct visual or audible feedback is provided to the operator indicating that a valid stimulation has occurred so that the operator may adjust the stimulation accordingly. A search algorithm may be used to direct a convergence to the motor threshold stimulation level with or without operator intervention. A motion detector is used or, alternatively, the motion detector is replaced with a direct motor evoked potential (MEP) measurement device that measures induced neurological voltage and correlates the measured neurological change to the TMS stimulus. Other signals indicative of motor threshold may be detected and correlated to the TMS stimulus pulses. For example, left / right asymmetry changes in a narrow subset of EEG leads placed on the forehead of the patient or fast autonomic responses, such as skin conductivity, modulation of respiration, reflex responses, and the like, may be detected. The appropriate stimulation level for TMS studies are also determined using techniques other than motor cortex motor threshold methods. For example, a localized ultrasound probe may be used to determine the depth of cortical tissue at the treatment site. When considered along with neuronal excitability, the stimulation level for treatment may be determined. Alternatively, a localized impedance probe or coil and detection circuit whose Q factor changes with tissue loading may be used to detect cortical depth.

A wall panel-ceiling engagement device is designed to couple a wall panel to a ceiling. The engagement device, when engaged with the ceiling, holds the wall panel stationary without any fasteners, braces or other securing members that penetrate into the ceiling. The engagement device includes a pair of wall extensions secured to opposite sides of the wall panel and that contain a sound and / or attenuating material, such as a foam material, therebetween. Corner braces are used to join adjacent wall-panels to one another. The corner braces also function to allow the wall panels to sway as a collective and connected unit during seismic events.

The method and the apparatus disclosed serve to acquire seismic induced movements. A coil and a permanent magnet are contained in an enclosure and the seismic movements induce a relative movement between said coil and said magnet. The current induced into the coil is appraised as a measure of said seismic movement. The position of the coil in relation to the permanent magnet is monitored by a position sensor. A closed loop control generates a current that is fed into the coil so that the coil settles at a given neutral position relative to the permanent magnet.

An assembly for measuring in vivo biomechanical properties of skin, comprising a testing device, said testing device comprising; a first pad attachable to the skin a second pad attachable to the skin, at a known distance from the first pad; said attachability of the pads to the skin to prevent relative movement between the respective pad and the skin to which it is attached; a forcing means for applying a force to the first pad, whilst said pads are attached to the skin, along a first axis connecting the first and second pad, to induce a corresponding relative movement between the pads due to deformation of the skin between said pads; a force measurement device for measuring the applied force, and; a displacement measurement device for measuring the corresponding induced movement.
