Patent application number	Description	Published
20100179423	Palpation Algorithms For Computer-Augmented Hand Tools - A method and system for performing minimally invasive tissue examination with a computer-assisted hand tool. The computer-assisted hand tool is moved into contact with the tissue under examination. An indication is received from a first sensor in the computer-assisted hand tool of each feature detected in a time interval during movement of the hand tool in contact with the tissue under examination. Each feature detected in the preset time interval is processed to determine a haptic feedback to provide to the user. A haptic feedback is generated and provided to the user via an actuator that is responsive to at least one feature detected in the time interval.	07-15-2010

20100137845	Tool Having Multiple Feedback Devices - Disclosed herein are systems and methods for managing how signals, which are sensed on a tool, are presented to an operator of the tool. According to one example of a method for managing signals, the method comprises allowing an operator to manipulate a tool having a plurality of output mechanisms mounted thereon. The method also includes sensing a property of an object located near or adjacent to a distal portion of the tool and processing the sensed property to obtain one or more output signals. Furthermore, the method includes applying the one or more output signals to one or more of the output mechanisms.	06-03-2010

20080197901	Multiple Pulse Width Modulation - A method of generating a MPWM signal for a portable device such as a cellular telephone. For a first duty cycle that includes a MPWM frequency having N magnitude levels, the method generates a first waveform comprising a first and a second On pulse during a first MPWM frequency period. The first and second On pulses are separated by an Off period.	08-21-2008
20080252594	Vibration Actuator with a Unidirectional Drive - A haptic feedback generation system includes a linear resonant actuator and a drive circuit. The drive circuit is adapted to output a unidirectional signal that is applied to the linear resonant actuator. In response, the linear resonant actuator generates haptic vibrations.	10-16-2008
20080287147	Haptically Enabled Messaging - A mobile terminal device receives a haptically enabled message that includes text and at least one haptic feedback command. The device determines the timing of the haptic feedback command within the message. When the device receives an indication that the message is being displayed by a user, the device synchronizes a haptic effect corresponding to the haptic feedback command. The synchronizing is based on the timing and the indication.	11-20-2008
20080303782	METHOD AND APPARATUS FOR HAPTIC ENABLED FLEXIBLE TOUCH SENSITIVE SURFACE - A method and apparatus for an electronic interactive device having a haptic enabled flexible touch sensitive surface are disclosed. In one embodiment, the electronic interactive device includes a flexible touch sensitive surface, a flexible screen (or display), and an actuator. The flexible touch sensitive surface is deposited over the flexible screen and is capable of receiving an input, such as, for example, from a user. The flexible screen displays an image via a displaying window. The actuator is coupled to the flexible screen and provides haptic feedback in response to the input.	12-11-2008
