Patent number: 6225976Abstract: A hand-held remote computer input peripheral is operable to be held by a human operator with one hand while both hands harmoniously manipulate a touch pad, function keys, and a click button provided with the input peripheral. The touch pad is positioned in a housing to be held by one hand while comfortably being addressed by the other hand, either with a finger or stylus, for controlling typical computer mouse functions and/or entering graphic images. The fingers of the hand holding the input peripheral rest naturally on the function keys and the click button such that keys and button can be activated simultaneously, or in conjunction with, activities of the hand manipulating the touch pad. The input peripheral is advantageously used in electronic meeting room applications having a computer and communication peripherals such as electronic white boards, presentation projectors, and video conferencing systems.Type: GrantFiled: October 30, 1998Date of Patent: May 1, 2001Assignee: Interlink Electronics, Inc.Inventors: William Allen Yates, Michael R. Smither, Jack A. Segal, Steven B. Branton, James D. Tickle, John K. Martinelli

Patent number: 7176889Abstract: An input device for an electronic system includes a force sensor having conductive interdigitated traces on a bottom substrate and a flexible substrate spaced apart from the bottom substrate. The flexible substrate has a resistive layer deposited on a bottom side facing the interdigitated traces. A snap dome is positioned over a portion of the force sensor flexible substrate. A flexible keymat membrane is positioned over the force sensor and the snap dome. The keymat membrane bottom surface faces the force sensor flexible substrate. The keymat membrane bottom surface has a protruding region surrounding the snap dome and spaced above the force sensor flexible substrate. A center keycap on the keymat membrane top surface is positioned over the snap dome. A surrounding keycap on the keymat membrane encloses the center keycap and is positioned over the keymat membrane protruding region.Type: GrantFiled: May 21, 2004Date of Patent: February 13, 2007Assignee: Interlink Electronics, Inc.Inventors: Jeffrey Ross Baker, James Dexter Tickle, Carlos Solis Sanchez, Scott David Alhart

Patent number: 7791596Abstract: A touch input device includes two or more interleaved scroll sensors. A common area is interposed between two of the scroll sensors. A sense line snakes through the common area. Scrolling pressure applied to a sense layer causes the sense layer to contact and electrically connect the sense line to the scroll sensors thereby permitting the scrolling pressure position to be determined by measuring a voltage on the sense line. The scroll sensors are potentiometric and may be linear strip scroll sensors or rotary ring scroll sensors. The interleaved scroll sensors with the common area allow smooth scrolling action from one major leg to another major leg.Type: GrantFiled: December 27, 2005Date of Patent: September 7, 2010Assignee: Interlink Electronics, Inc.Inventors: Michael Errico, Jeffrey R. Baker

Patent number: 6084572Abstract: A computer input device that has the click function incorporated into a pointing device, rather than as a separate switch. The pointing device implements the operations of pointing, clicking and dragging based solely upon an evaluation of the pressure applied thereto. An array of sensors is monitored. The cursor direction is determined by the difference or ratio of applied force between the arrayed sensors. Cursor velocity is determined by the magnitude of the applied force. When a click is desired, the pointing device is pressed downward. The transient nature of the top or its nearly vertical force nature causes the output of the pointing device to readly distinguish between pointing and clicking operations.Type: GrantFiled: May 9, 1997Date of Patent: July 4, 2000Assignee: Interlink Electronics, Inc.Inventors: Stuart I. Yaniger, Stewart M. Findlater

Patent number: 8531392Abstract: An apparatus and method for using a scroll sensor providing a touch sensitive control input surface for a plurality of control functions is provided. The input surface is divided into a plurality of regions. Each region is assigned to one of the plurality of control functions. At least one of these control functions accepts parametric control input. A first touch is received at one of the regions on the input surface. The control function assigned to the touched region is selected. If the selected control function is one of the control functions accepting parametric control input, a second touch on the input surface is received as parametric control input during an activation period for the selected control function. The second touch may be received as parametric control input at any point of the input surface.Type: GrantFiled: July 29, 2005Date of Patent: September 10, 2013Assignee: Interlink Electronics, Inc.Inventors: Steve B. Branton, Jeffrey R. Baker, David Lee Stallard, Dustin J. Luck

Patent number: 5828363Abstract: A thermally stable, mass-producible pointing device (10) producing an analog signal proportional to an applied force comprises actuator (20), including an arm (22) and a force transfer member (26), a connector (44), and a sensor (50). The connector maintains the force transfer member in contact with the sensor yet allows the force transfer member to change dimensions with ambient temperature without inducing stresses detectable by the sensor. In a preferred embodiment, the connector comprises an elastomeric adhesive and the sensor comprises a force-sensing resistor. The force transfer member is prevented from coming out of the assembly either by a retainer (12) comprising a shell or a potting compound retaining the force transfer member but permitting thermal expansion or contraction of the force transfer member. The force transfer member typically has a rounded or bevelled bottom surface (28) so the actuator rocks under an applied force.Type: GrantFiled: August 18, 1997Date of Patent: October 27, 1998Assignee: Interlink Electronics, Inc.Inventors: Stuart I. Yaniger, Mark C. Pickett

Publication number: 20010040551Abstract: A hand-held remote computer input peripheral for communicating with a host computer having a display screen. An operator holds the input peripheral in space with a first hand. The input peripheral includes activation mode buttons each corresponding to a respective activation mode of the touch pad for controlling the display screen. The activation modes include a text entry mode for entering text on the display screen and a cursor control mode for controlling a cursor on the display screen. The input peripheral further includes a touch pad. The operator manipulates the touch pad using a second hand while holding the input peripheral with the first hand to perform functions associated with the activation modes for controlling the display screen. The text entry mode includes an annotation mode for enabling the operator to draw on to the display screen and a type mode for enabling the operator to print text on to the display screen.Type: ApplicationFiled: July 29, 1999Publication date: November 15, 2001Applicant: Interlink Electronics, Inc.Inventors: WILLIAM ALLEN YATES, MICHAEL R.
