Publication number: 20030016207Abstract: A man-machine interface which provides tactile feedback to various sensing body parts is disclosed. The device employs one or more vibrotactile units, where each unit comprises a mass and a mass-moving actuator. As the mass is accelerated by the mass-moving actuator, the entire vibrotactile unit vibrates. Thus, the vibrotactile unit transmits a vibratory stimulus to the sensing body part to which it is affixed. The vibrotactile unit may be used in conjunction with a spatial placement sensing device which measures the spatial placement of a measured body part. A computing device uses the spatial placement of the measured body part to determine the desired vibratory stimulus to be provided by the vibrotactile unit. In this manner, the computing device may control the level of vibratory feedback perceived by the corresponding sensing body part in response to the motion of the measured body part. The sensing body part and the measured body part may be separate or the same body part.Type: ApplicationFiled: June 27, 2002Publication date: January 23, 2003Applicant: Immersion CorporationInventors: Mark R. Tremblay, Mark H. Yim

Patent number: 6413229Abstract: A man-machine interface is disclosed which provides force information to sensing body parts. The interface is comprised of a force-generating device (106) that produces a force which is transmitted to a force-applying device (102) via force-transmitting means (104). The force-applying device applies the generated force to a sensing body part. A force sensor associated with the force-applying device and located in the force applicator (126) measures the actual force applied to the sensing body part, while angle sensors (136) measure the angles of relevant joint body parts. A force-control unit (108) uses the joint body part position information to determine a desired force value to be applied to the sensing body part. The force-control unit combines the joint body part position information with the force sensor information to calculate the force command which is sent to the force-generating device.Type: GrantFiled: February 9, 2000Date of Patent: July 2, 2002Assignee: Virtual Technologies, INCInventors: James F. Kramer, Mark H. Yim, Marc R. Tremblay, Daniel H. Gomez

Patent number: 6378634Abstract: A tracking device includes an external member and an internal member rotatable relative to the external member. A motor is attached to the internal member and includes a rotor shaft attached to the external member. A pair of target sensors that sense a phenomenon such as a magnetic field, sound, light or RF radiation, provide input to a controller that controls rotation of the motor. Angular acceleration of the internal member will cause an equal and opposite angular acceleration of the external member and the tracking device will roll toward the target. The tracking device may hop by suddenly stopping the rotation of the internal member or by suddenly decreasing or increasing the acceleration of the motor or by inserting a linkage fixed to the external member into the rotation path of the internal member.Type: GrantFiled: November 28, 2000Date of Patent: April 30, 2002Assignee: Xerox CorporationInventor: Mark H.

Patent number: 6123316Abstract: Construction of fluid conduit systems in printed circuit boards or other dielectric laminate substrates is disclosed. The fluid conduits can be angled or curved to provide greater directional control of fluid flow. Conduits are created by lamination of a first laminate layer and a second laminate layer. The first laminate layer is composed of a dielectric base material impregnated with a resin, with a first aperture defined therethrough, while the second laminate layer has a second aperture. The second aperture is positioned with respect to the first aperture to only partially overlap, together defining an angled conduit. Fluid flow through the conduits can be controlled using microdevice valves.Type: GrantFiled: November 27, 1996Date of Patent: September 26, 2000Assignee: Xerox CorporationInventors: David K.

Patent number: 6098661Abstract: A valve for redirecting fluid flow has a valve chamber supporting fluid flow, with the valve chamber having an inlet, a first outlet, and a second outlet. The valve chamber can be closed or partially open. The flap element is movable to alternatively block the first outlet and the second outlet. In or immediately adjacent to the valve chamber are opposing first and a second catch mechanisms for controllably latching the flap element to block respectively the first outlet and the second outlet. The first and second catch mechanisms have a disabled state and an activated state for holding and allowing release of the flap element. Once the first or second catch mechanism is disabled, the flap element is free to move to another position, provided it can overcome the mechanical fluid flow forces that tend to hold it in position.Type: GrantFiled: December 19, 1997Date of Patent: August 8, 2000Assignee: Xerox CorporationInventors: Mark H.
