  • Publication number: 20240123182
    Abstract: Aspects of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath with a tubular inner liner wound in a spiral configuration such that a plurality of protrusions is disposed in an overlapping portion of the sheath. The disclosed sheath is configured to expand from a predetermined rest diameter dr to an expanded diameter de during application of a radial outward force by passage of a medical device through the sheath.

  • Patent number: 8913670
    Abstract: A system and method are provided that can be used for applying a deblocking filter to a video according to processor usage, in particular on a mobile device. To determine which of a plurality of deblocking filters to use, the system determines an environment indicator indicative of current processor usage, compares the environment indicator to a primary threshold, wherein the primary threshold is indicative of a maximum acceptable processor usage. If the primary threshold is met, the system foregoes any deblocking filtering. If however the primary threshold is not met, the environment indicator is compared to one or more secondary thresholds and a respective one of the plurality of deblocking filters is applied to the video according to which one of the secondary thresholds is met. Each of the plurality of deblocking filters has a different complexity and thus can be chosen to suit the current system environment.

  • Patent number: 8885733
    Abstract: A processor and method are provided for decoding a multimedia file having video and audio data streams that are configured to be played in synchronization. Frames of the video stream are decoded and played with the audio and, to compensate for saturation of the processor usage, two procedures are performed. The first procedure operates at a first periodic interval and slows down the frame rate to reduce processor usage if needed. The second procedure first attempts to speed up the video to catch up to the audio if they are out of sync and if this cannot be done in the next time interval, the decoding of a select number of frames is skipped such that the video and audio data streams are resynchronized.

  • Patent number: 8878784
    Abstract: Method and arrangement for affecting diagonal movement of a cursor 171 on a display screen 322 of a handheld communication device 300. The method includes sensing movement at an auxiliary user input 328 of the handheld communication device 300 indicative of a user's desire to affect diagonal movement of the cursor 171 on the display screen 322 of the handheld communication device 300. X-direction signals and Y-direction signals are produced based on the sensed movement at the auxiliary user input 328. During that time while necessary signals are being collected and processed, the cursor 171 is held steady on the display screen 322 until a predetermined criterion is met for discriminating whether the user has indicated x-direction cursor movement, y-direction cursor movement or diagonal cursor movement.
