  • Publication number: 20170017306
    Abstract: Embodiments of display control based on dynamic user interactions generally include capturing a plurality of temporally sequential images of the user, or a body part or other control object manipulated by the user, and computationally analyzing the images to recognize a gesture performed by the user. In some embodiments, a scale indicative of an actual gesture distance traversed in performance of the gesture is identified, and a movement or action is displayed on the device based, at least in part, on a ratio between the identified scale and the scale of the displayed movement. In some embodiments, a degree of completion of the recognized gesture is determined, and the display contents are modified in accordance therewith. In some embodiments, a dominant gesture is computationally determined from among a plurality of user gestures, and an action displayed on the device is based on the dominant gesture.

  • Publication number: 20160323095
    Abstract: A hybrid numeric-analog clock synchronizer, for establishing a clock or carrier locked to a timing reference. The clock may include a framing component. The reference may have a low update rate. The synchronizer achieves high jitter rejection, low phase noise and wide frequency range. It can be integrated on chip. It may comprise a numeric time-locked loop (TLL) with an analog phase-locked loop (PLL). Moreover a high-performance number-controlled oscillator (NCO), for creating an event clock from a master clock according to a period control signal. It processes edge times rather than period values, allowing direct control of the spectrum and peak amplitude of the justification jitter. Moreover a combined clock-and-frame asynchrony detector, for measuring the phase or time offset between composite signals. It responds e.g. to event clocks and frame syncs, enabling frame locking with loop bandwidths greater than the frame rate.

  • Patent number: 9348419
    Abstract: First and second detection systems coupled to a controller are synchronized, with the first detection system including first emission and detection modules while the second detection system includes a second detection module, for emitting radiation towards and detecting radiation from a region. A pulse of radiation emitted from the first emission module is detected by the first and second detection modules for a first time interval starting at time T1 and for a second time interval starting at time T2, respectively. The radiation received is compared to determine a radiation difference measurement. The starting time T2 is adjusted relative to starting time T1 based at least in part upon the radiation difference measurement to determine a revised starting time T2, thereby aiding the synchronization of starting time T2 with starting time T1.

  • Publication number: 20150331966
    Abstract: There is disclosed a method of designing a panel assembly for a vibratory panel device, the assembly comprising a panel which supports vibrations and two or more transducers coupled to the panel to transmit vibrations to or receive vibrations from the panel. The method comprises: obtaining the number of transducers to be used in the assembly and their relative positions; obtaining relationships between drive signals to be applied to the respective transducers to provide a desired effect; determining an optimisation criterion for the assembly that depends on the obtained relationships; and determining one or more parameters for the respective transducers that satisfy the optimisation criterion. The one or more parameters may be selected from amplitudes of drive signals, spacing, activity, area, position, shape, dimension.

  • Patent number: 9186268
    Abstract: A system for tissue approximation and fixation is described herein. A device is advanced in a minimally invasive manner within a patient's body to create one or several divisions or plications within a hollow body organ. The system comprises a stapler assembly having a tissue acquisition member and a tissue fixation member. The stapler assembly approximates tissue from within the hollow body organ with the acquisition member and then affixes the approximated tissue with the fixation member. In one method, the system can be used as a secondary procedure to reduce the size of a stoma within the hollow body organ.

  • Publication number: 20150138157
    Abstract: There is provided a method of generating a primary effect in a vibratory panel device comprising at least N+M transducers connected to a panel, where N and M are integers greater than or equal to 1. Each transducer is electrically connected to signal processing circuitry and the signal processing circuitry is configured to receive signals from or provide signals to each transducer. The method comprises: obtaining N electrical signals to be applied respectively to N of the transducers to produce the primary effect; and processing the N electrical signals to produce M additional electrical signal(s), such that when the M signal(s) are applied to respective transducers other than the N transducers, a secondary effect is produced. The secondary effect may be for example cancellation of any audio output resulting from providing haptic feedback.

  • Patent number: 9028511
    Abstract: Devices and methods for tissue acquisition and fixation, or gastroplasty, are described. Generally, the devices of the system may be advanced in a minimally invasive manner within a patient's body, e.g., transorally, endoscopically, percutaneously, etc., to create one or several divisions or plications within the hollow body organ. Such divisions or plications can form restrictive barriers within a organ, or can be placed to form a pouch, or gastric lumen, smaller than the remaining stomach volume to essentially act as the active stomach such as the pouch resulting from a surgical Roux-En-Y gastric bypass procedure. Moreover, the system is configured such that once acquisition of the tissue by the gastroplasty device is accomplished, any manipulation of the acquired tissue is unnecessary as the device is able to automatically configure the acquired tissue into a desired configuration.
