Abstract: A user device may include one or more features on a surface of the user device, where a user may interact with the one or more features. In response to a user action with respect to one of the features, a particular sound, frequency, or change in frequency may be output. An augmented reality functional node (ARFN) may detect the sound or frequency and identify a particular operation that corresponds to the sound or frequency. The ARFN may then cause that operation to be performed within an environment.

Abstract: A device includes a projection and camera system to create an augmented reality environment in which images are projected onto a scene and user movement within the scene is captured. The projection and camera system have a camera to image scattered IR light from the scene and compute time of flight values used in depth mapping of objects in the room. The system also has a projector to project the images onto the scene. The system controls the camera and projector mounted in a moveable head of a lamp with a motor mounted elsewhere in the lamp. In one implementation, the motor is mounted in the base of a table lamp.

Abstract: Two or more imagers having associated frame rates are each configured with a global shutter having an exposure interval less than a frame interval. The exposure interval for a first imager is offset from the exposure interval of a second imager such that the first imager is exposed while the second imager is not exposed. When interleaved, an effective frame rate exceeds the individual frame rates provided by the individual imagers. This interleaved imaging system may be used to recover, at high frame rates, images that are projected from spatial light modulators.

Abstract: An apparatus for controlling the temperature of a reaction mixture contained in a chamber of a reaction vessel comprises a thermal surface for contacting a flexible wall of the chamber and an automated machine for increasing the pressure in the chamber. The pressure increase in the chamber is sufficient to force the flexible wall to conform to the thermal surface for good thermal conductance. The apparatus also includes at least one thermal element for heating or cooling the surface to induce a temperature change within the chamber.

Abstract: A reaction vessel having a reaction chamber for holding a sample is fabricated by producing a housing having a rigid frame defining the minor walls of the chamber. The housing also defines a port for introducing fluid into the chamber. At least one sheet or film is attached to the rigid frame to form at least one major wall of the chamber. In preferred embodiments, two sheets or films are attached to opposite sides of the rigid frame to form two opposing major walls of the chamber, the major walls being connected to each other by the minor walls.

Abstract: Hard biasing of a magnetoresistive sensor or a spin valve sensor in a magnetic read head is initialized by repeatedly applying a magnetic field to the hard biasing at any level of fabrication of the magnetic read head or any combination of levels of fabrication of the read head such as at the wafer level, row bar level, single slider level, head gimbal assembly (HGA) level and/or head stack assembly (HSA) level.

Abstract: A device for providing user input to a computer includes a base member with a tracking sensor. A vertically oriented pistol grip member is disposed at an aft portion of the base member and extends upward therefrom. A pistol barrel member extends forward from an upper portion of the pistol grip member. The counterweight is disposed toward the aft portion of the base member so as to counterbalance a weight of the pistol barrel member and a weight of the pistol grip member. The counterweight can also provide a stabilizing force when the user holds and operates the pistol grip member.

A tracking sensor for sensing motion of the base member is mounted in the base member at a sensor location along the base axis. A vertical grip member extends upward from the base member. A major axis of the vertical grip member intersects the base axis at a grip axis location that is offset from the sensor location by a distance greater than zero.

Abstract: The present invention provides an apparatus for performing heat-exchanging chemical reactions, such as nucleic acid amplification. The apparatus includes a reaction vessel having a chamber for holding a sample for chemical reaction and optical detection. The vessel has a rigid frame defining the side walls of the chamber, and flexible sheets attached to opposite sides of the frame to form opposing major walls of the chamber. The frame further includes a port and a channel connecting the port to the chamber. The temperature of the sample is controlled by opposing plates positioned to receive the chamber of the vessel between them. The apparatus also includes a plunger which is inserted into the channel of the vessel to seal the port and increase pressure in the chamber. The increased pressure forces the flexible major walls of the chamber to contact and conform to the surfaces of the plates, thus ensuring optimal thermal conductance between the plates and the chamber.
