Abstract: A system and method for powering a radio frequency identification (RFID) module includes an energy harvesting system configured to passively generate a voltage, a voltage regulator configured to regulate the passively generated voltage and a controllable port through which the passively generated voltage is provided to the RFID module.

Abstract: Methods and techniques to implement a digital signal processor for avoidance of audio feedback are disclosed, in particular, audio signal processing systems that reduce the requirement for physical segregation of sound acquisition and diffusion zones. In a more general aspect, the components and techniques described herein provide a for a sound space and sound processing equipment such that sound travelling electronically in a loop through the sound processing equipment that is output into a physical sound diffusion zone, received at the input to the sound processing equipment, and then re-amplified, etc. is attenuated over that loop by frequency modification. The frequency modification is such that, at least for some signals, on each pass through the loop, the sound processing equipment will attenuate or amplify individual sub-bands of the frequency spectrum of the audio signal that is received at the input of the sound processing equipment.

Abstract: A drive system is presented for controlling rotation of a sphere. The system facilitates holonomic motion of a drive with respect to a sphere such that a holonomic drive or drives may be maintained at a relative position with respect to a sphere. The motion of a sphere may be controlled by controlling the position of a drive with respect to the sphere. The drive may be controlled by way of a controller. A holonomic drive may be urged against a sphere by way magnetic interaction of the holonomic drive and a second structure. Also, a support structure is facilitated that allows a sphere to pass through a support column without breaks or interruptions in the sphere.

Abstract: Disclosed are touch detection systems and methods. In one embodiment, a display panel enabling touch detection comprises a touch pane configured to allow a light including a detection light, a back inner surface, and a display generation module located between the touch pane and the back inner surface. The display generation module is configured to produce a visual display at the touch pane. The display generation module is further configured to pass the detection light received from the touch pane. The display panel also comprises a detection light receiver situated at the back inner surface configured to detect the detection light received through the display generation module for enabling a detection of touches to the touch pane of the display panel.

Abstract: A method and system of selectively projecting images is disclosed. An illuminated area is created on a projection surface by directing a light source to the projection surface. The illuminated area is detected with a camera. Electrical signals are transmitted from the camera to the projector, the electrical signals being indicative of the position of the illuminated area in relation to the projection surface. Based on the received electrical signals, an image and a second image are projected on the projection surface. The image is projected on the illuminated area of the projection surface. The second image is projected on an area of the projection surface that is not illuminated by the light source. Applications of this method and system include the projection of background and foreground images creating the illusion of an x-ray beam, the projection of a normal image and an overblown image creating the illusion of a magnifying light beam.
