摘要:
An exemplary method for multi-tier pacing includes delivering single site, left ventricular pacing, sensing patient activity; comparing the sensed patient activity to a patient activity threshold and, if the sensed patient activity exceeds the patient activity threshold, then delivering multi-site, left ventricular pacing for a predetermined period of time and, after the predetermined period of time, delivering single, site left ventricular pacing. In such a method, the period of time may be determined based on cardio-pulmonary demand. Other exemplary technologies are also disclosed.

An epicardial lead is passively fixed in a pericardial space by a passive fixation member. The passive fixation member extends from a distal portion of an epicardial lead and acts against a pericardial layer and an epicardial layer to hold the lead in place. The epicardial lead may include an electrode that is connected to a conductor that extends from a distal portion of the lead. In some embodiments the epicardial lead includes a material that promotes fibrosis to fix the lead to heart tissue. The passive fixation member may include a shocking coil.

Embodiments include electrical leads and methods of using electrical leads that may be used for delivering both cardioversion/defibrillation signals and pacing signals and sensing to target tissue. Some of these embodiments may also be used to sense and transmit electrical signals from target tissue. Some electrical lead embodiments are configured to be delivered into a patient's intrapericardial space by non-invasive methods.

An implantable sensor is provided that includes a piezopolymer sensor element including a body having a plurality of layers of a piezopolymer, and an attachment device configured to hold the piezopolymer sensor element in direct contact with at least one of a bodily fluid and bodily tissue such that the piezopolymer sensor element is configured to bend in response to motion of the at least one of bodily fluid and bodily tissue. A pair of electrodes is attached to the piezopolymer sensor element and the electrodes are configured to collect an electrical charge that is generated within the piezopolymer sensor element due to the bending of the piezopolymer sensor element.

A system and method are provided for mixing song data based on measure groupings. A player or program may recognize measure groupings in a song through identifying cuepoints. The player or program may use the cuepoints and/or other identifiers of measure groupings to generate a transition between the song and other songs. Parts of one or both songs may be time-stretched, or frames may be added or deleted, such that the beats in both songs are substantially aligned during the transition. The system and method may also involve altering the sequence of frames in one or both of the songs, so that the transition may have various sonic qualities as desired by a user. A choice of transition modes may be provided via a user interface that allow the user some control over when and how transitions between songs are executed.
摘要:
A system and method are provided for generating cuepoints for mixing song data. One or more people may listen to a song and identify measure groupings within the song. The one or more people might generate markings corresponding to these measure groupings and submit the markings to a cuepoint generation system. The markings may then be reconciled into cuepoints that may be used for mixing the song with other song data. In some embodiments, the cuepoints may be adjusted based on characteristics of the particular songs that are to be mixed together.
摘要:
Encoding a video signal according to a scalable video coding (SVC) technique employs two different encoding paths for the base layer and the enhancement layers respectively, whereby the two encoding paths share common hardware encoding modules. For example, a control module can route received video information associated with the base layer directly to the hardware encoder modules for encoding, while routing video information associated with the enhancement layers to an upscaler. The upscaled video information is then provided to the hardware encoder module for processing in similar fashion to the base layer information. The hardware encoder provides encoded video information to another control module, which determines whether to route the information to a hardware or software entropy encoder, based on whether the encoded video information is associated with the base layer or an enhancement layer, respectively.
摘要:
A collapsible spider wheel assembly on a towing device enables storage of the device into a standard rectangular space. Once collapsed, the collapsible spider assembly is protected within the body of the towing device. Furthermore, actuation of the folding and unfolding may be accomplished through the usual telescoping of the carrying handle of such a device, such as in a suitcase embodiment. While the spider wheels are in the open position, the carrying apparatus may exert a drive force to climb up stairs and braking force to descend stairs. The unit operates as a normal wheeled carrying apparatus while traversing a horizontal surface.
