  • Patent number: 9191744
    Abstract: A system and method for interjecting ambient background sounds into a set of headphones is provided. The system monitors an ambient sound environment and compares the ambient sound environment to a preset set of sound characteristics (e.g., frequency signatures, amplitudes and durations) in order to detect important or critical background sounds (e.g., alarm, horn, directed vocal communications, crying baby, doorbell, telephone, etc.). When a critical background sound is detected, the system interjects either a notification signal or a portion of the ambient background into the audio stream, thus alerting a user of a potentially important sound or event occurring within their immediate vicinity.

  • Patent number: 9191758
    Abstract: A method of fabricating a custom-fit in-ear-monitor (IEM) is provided that utilizes a pre-tuned, single piece driver module to simplify fabrication and reduce cost while insuring that the performance of the IEM consistently meets the acoustic goals set for the device. During fabrication the driver module, the drivers coupled to the module's driver ports, and the crossover circuit are installed in a custom-fit IEM shell such that the module's acoustic output is aligned with the output surface of the IEM shell. After installing the device components within the IEM shell, the shell is sealed.

  • Patent number: 9169962
    Abstract: Systems and methods related to computer peripheral devices and mounts are described including device mounts with three linkages. A first linkage may include a body, an abutment piece approximately perpendicular to the body, and a device attachment mechanism disposed proximate to said abutment piece. A second linkage is rotatably connected to the first linkage and a third linkage is rotatably connected to the second linkage. The third linkage may at least partially overlaps the second linkage and extend beyond an end of the second linkage. A camera housing may also be attached to the first linkage, e.g. by a hinge or socket joint. The second linkage may be connected to the first linkage via a friction hinge, and the third linkage may be connected to the second linkage via another friction hinge. The third linkage may preferably include a substantially planar contact surface with a chamfered leading edge.

  • Patent number: 9128714
    Abstract: Embodiments of the invention are directed to control devices configured for use with computing devices. More specifically, the present invention relates to methods and devices for performing presence detection of an object body near a device. The methods and devices described herein may include comparing a reference signal against an over the air signal to determine whether a phase difference exists between the reference signal and the over the air signal. The existence of a phase difference may be indicative of a object or body in proximity to the device.

  • Publication number: 20150234484
    Abstract: An input device is communicatively coupled to a host, wherein a movement of the input device is measured relative to a reference surface, and wherein the friction between the input device and the said reference surface is dynamically reducible. The input device comprises a housing and an actuator for contacting the reference surface. The actuator comprises a first layer comprising a piezo-electric material to which a voltage is applied and a second layer, comprising a material different than the first layer, bonded to the first layer. The application of voltage to the first layer results in a layer of air being trapped between the actuator and the reference surface. The layer of air reduces the friction from a first amount of friction to a second amount of friction between the input device and the reference surface.

  • Publication number: 20150211839
    Abstract: Embodiments of the invention are directed to input devices configured for use with computing devices. The present invention relates to input devices configured with a plurality of sensors configured to determine the displacement and position of the input device. Tracking of the input device may be switched from an optical sensor to an inertial sensor based on the speed of movement of the input device or based on the input device detecting that loss of tracking has occurred. In some embodiments, a gyroscope may be configured to modify data from the inertial sensor module to correct for fictitious accelerations generated when the input device is rotated.

  • Patent number: 9091903
    Abstract: Embodiments of the present invention include a camera having two modes: a visible light imaging mode (day-mode) and an IR imaging mode (night-mode). In the visible light imaging mode, an IR filter is in line with the lens assembly. In the IR imaging mode, the IR filter is mechanically removed, and IR light is allowed to pass to the sensor. In one embodiment, in the IR imaging mode, IR lighting is provided by an IR LEDs on the camera to illuminate the scene. In one embodiment, the various components are chosen, balanced and optimized so that images captured using visible light and images captured using non-visible light are both in focus. In one embodiment, an algorithm determines when there sufficient visible light is present and when it is not, and thus determines when to switch the camera from one mode to another.

  • Patent number: 9092071
    Abstract: A control device includes a two-dimensional inertial system configured to measure an acceleration of the control device. A control circuit is coupled to the two-dimensional inertial system where the control circuit is configured to receive acceleration information for the acceleration measured by the two-dimensional inertial system. The control circuit is further configured to integrate the acceleration information to calculate the velocity of the control device and determine if the velocity of the control device becomes zero along one or both of the two dimensions for which the two-dimensional inertial system is configured to measure acceleration. The control circuit is further configured to correct a drift in the velocity if the control circuit determines that the velocity is zero along one or both of the two dimensions.

  • Patent number: 9092129
    Abstract: A capture device for remote, virtual on screen data input by hand annotation comprises at least three functional layers including a bottom rigid layer, a middle pressure sensor layer and a top flexible layer. The bottom rigid layer has a surface that provides a mechanical support for writing. The middle pressure sensor layer is adapted to measuring a pressure array or map on the capture active area and to send data representing the measured pressure to a personal computer. The top flexible touch-sensitive passive LCD display layer includes an LCD surface by which whatever is written down on the LCD is impressed graphically due to its liquid crystal physical properties wherein applied pressure changes the crystal particles orientation and light properties, such that when a stylus presses against a writing surface thereof, it leaves a visible trace allowing the user to produce a drawing though no real ink has flown.
