  • Patent number: 9104791
    Abstract: Systems and methods for simulating a medical procedure are disclosed. For example, one described system for simulating a medical procedure includes a physics module configured to model at least one physical property of a user-defined organic object associated with a patient; a display module configured to cause a display of the user-defined organic object; a script module configured to execute a user-defined medical procedure script; a simulation module in communication with the physics module, the display module, and the script module, the simulation module configured to execute a simulation of the medical procedure based at least in part on the user-defined model of the organic object and the user-defined medical procedure script.

  • Patent number: 8717852
    Abstract: Systems and methods for monitoring motion parameters of an object are described in the present disclosure. In an embodiment, a sensor, coupled to a housing, senses motion associated with the housing and provides a sensor output based on the sensed motion. A processing device receives the sensor output, accumulates counts associated with the sensor output, and provides an output once a threshold associated with the accumulated counts is reached. A vibrotactile device, that receives the output from the processing device, provides a haptic output in response to the output from the processing device.

  • Patent number: 8351299
    Abstract: Systems and methods for monitoring motion parameters of an object are described in the present disclosure. In one embodiment among many, a sensor, coupled to a housing, senses motion associated with the housing and provides a sensor output based on the sensed motion. A processing device receives the sensor output, accumulates counts associated with the sensor output, and provides an output once a threshold associated with the accumulated counts is reached. A vibrotactile device, that receives the output from the processing device, provides a haptic output in response to the output from the processing device. In one embodiment among many, a toothbrush is described as a monitoring mechanism for monitoring a plurality of brush strokes that a user executes with the toothbrush. The monitoring mechanism is incorporated in the handle of the toothbrush. The monitoring mechanism may be used to provide an alert once a sufficient number of brush strokes is achieved.
