20080287824 | Systems and Methods for Locating A Blood Vessel - Systems and methods for locating a blood vessel are described. One described method includes receiving a first temperature measure associated with a first point on a surface of a skin; receiving a second temperature measure associated with a second point on the surface of the skin, and determining a differential between the first temperature measure and the second temperature measure. The method further includes generating an output signal indicating the presence of a blood vessel if the differential exceeds a threshold. | 11-20-2008 |
20090053683 | Flexible Member Based Simulator - A simulator includes a motor and a flexible member coupled to the motor. The simulator further includes a processor that is coupled to the motor and controls the motor to vary the tension of the flexible member. | 02-26-2009 |
20090245601 | Locating Blood Vessels - Several systems and methods for locating blood vessels are described in the present disclosure. One of the implementations of a blood vessel locating system comprises an image capture device and processing circuitry. The image capture device is configured to capture a first image of a region of the skin of a subject when the region is illuminated by a first light and to capture a second image of the region of the skin when the region is illuminated by a second light. The processing circuitry is configured to calculate the difference between the first image and the second image to obtain a differential image. The processing circuitry is further configured to enhance the differential image to obtain an enhanced image of blood vessels located under the surface of the skin of the subject. | 10-01-2009 |
20090320227 | Apparatus and Method for Providing Condition-Based Vibrotactile Feedback - 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. | 12-31-2009 |
20100069941 | Systems and Methods For Sensing Hand Motion By Measuring Remote Displacement - Systems and methods for sensing hand motion by measuring remote displacement are disclosed. For example, one disclosed apparatus includes a first surface configured to engage a first distal member of a surgical tool and a second surface configured to engage a second distal member of the surgical tool, the second surface coupled to the first surface at a pivot point. The apparatus further includes a sensor configured to detect a relative movement of the first surface and the second surface about the pivot point and to generate a signal based at least in part on the relative movement. | 03-18-2010 |
20110148794 | Haptic Interface for Palpation Simulation - A method for interfacing a user with a computer running an application program, the computer generating a graphical environment comprising a graphical object and a graphical representation of at least a portion of a living body, comprises providing an object in communication with the computer, controlling the graphical object in relation to manipulation of at least a portion of the object by the user, and outputting a haptic sensation to the user when the graphical object interacts with a region within the graphical representation to provide the user with haptic feedback related to a simulated palpation of the region. | 06-23-2011 |
20130120153 | Apparatus for Providing Condition-Based Vibrotactile Feedback - 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. | 05-16-2013 |
20140149067 | IMPACT AND ACCELERATION DETECTION - An sensor system measures acceleration and detects impacts. According one embodiment of the present invention, an impact sensor system attaches to a helmet, detects impacts, and displays indications of single and cumulative impacts. Identifying impacts when they occur can help identify players to be screened for concussion or taken out of action before they show symptoms. This can help prevent concussions that result from cumulative hits, which are often more dangerous than those that result from a single hit. The system serves as a continue-to-play decision support aid. | 05-29-2014 |
