Patent number: 8497840Abstract: A computer peripheral that may operate as a hand-held scanner and, in some embodiments, also as a conventional computer mouse. The components incorporated in the device to support scanning may be compact and may be positioned to allow flexibility in shaping a housing of the device. As a result, the device may be ergonomically shaped to facilitate hand-held use as either a scanner or a mouse. Controls, for mouse or scanner operation, may be readily incorporated into the device. The components may also be low cost. Such a low cost, compact design may be achieved through an appropriate selection of curved reflective surfaces in optical paths through the housing. The curved reflective surface may selectively focus or spread light traveling along an optical path, reducing or eliminating the need for lenses and may enable light emitting elements and an image array to be mounted on the same printed circuit board.Type: GrantFiled: March 25, 2010Date of Patent: July 30, 2013Assignee: Dacuda AGInventors: Martin Georg Zahnert, Erik Fonseka, Alexander Ilic

Patent number: 8390572Abstract: A touch-sensitive display surface having touch-capacitive and vibration sensors. This surface allows the user to rest their fingers on the keys of an onscreen keyboard and type as they would on a regular keyboard. As the user places their fingers on the touch screen, the system relocates the onscreen keyboard to the location where the fingers are resting. The touch sensors report the signal strength level of each key touched to a processor, but no keystroke is issued by the processor until a corresponding “tap” (i.e., vibration) is detected. When a tap is detected, the processor references the status of the touch capacitance sensors before, during, and/or immediately after the moment in time the tap occurred. The size, position, and orientation of the onscreen keyboard keys are dynamically set as determined by the user initiating a home-row definition event by resting their fingers momentarily on a virtual home-row.Type: GrantFiled: February 3, 2012Date of Patent: March 5, 2013Assignee: Cleankeys Inc.Inventors: Randal J. Marsden, Steve Hole

Patent number: 8325141Abstract: A touch sensitive surface having touch-capacitive and vibration sensors. This surface allows the user to rest their fingers on the keys and type as they would on a regular keyboard. As the user places their fingers on the keys, the touch capacitive sensors (one per key) report the signal strength level of each key touched to a processor, but no keystroke is issued by the processor until a corresponding “tap” (ie. vibration) is detected. When a tap is detected, the processor references the status of the touch capacitance sensors before, during, and/or immediately after the moment in time the tap occurred.Type: GrantFiled: September 19, 2008Date of Patent: December 4, 2012Assignee: Madentec LimitedInventor: Randal J.
