Abstract: In accordance with some implementations, various embodiments of a guidewire or catheter having an elongate core with a helical section are provided. In accordance with one implementation, a guidewire is provided. The guidewire includes a core wire having a proximal end, a distal end and is defined by an outer surface between the proximal end and the distal end of the core wire. The core wire has a centerline that traverses the length of the core wire from the proximal end to the distal end of the core wire. The centerline is located approximately at the center of mass along the core wire within the outer surface of the core wire. Preferably, the core wire has a substantially straight proximal portion and a helically curved segment located distally with respect to the proximal portion. The centerline of the core wire is substantially straight along the straight proximal portion, and, the centerline is helically curved along the helically curved segment.

Abstract: A computer-implemented method, system and computer program product are used to provide a factor in a first domain for a first set of data and in a second domain for a second set of data. The computer-implemented method, system and computer program product then determine a relationship between the domains in term of the factor. The computer-implemented method, system and computer program product determine for the first domain whether the factor from the second domain has changed, and if so, create domain specific records for the first domain in response to determining that the factor from the second domain has changed.

Abstract: A system and method for disseminating digital content, including receiving a video stream having embedded time code markers, copying the video stream, distributing a first copy to a player with a desired delay, distributing a second copy for association of content, and associating content with the second copy during the delay for playing of the first copy and the associated content at the player.

Abstract: A discharge prevention system for a primary battery comprises an energy harvesting module that produces energy from an environment and a control circuit for applying electrical current to the primary battery from the energy harvesting module to prevent or reduce self-discharge. This system will prevent or reduce rapid self-discharge at high temperatures in lithium-based primary batteries, for example. It can significantly extend the operating lifetime of such batteries operating at high temperature, particularly in applications where battery power is used intermittently. Specifically, a very low current is supplied to the primary battery at high temperature, significantly extending its storage lifetime. In some cases, depending on the current characteristics of the battery, the energy associated with the bias current can be in the same order of magnitude as the energy that would be lost by self-discharge, but in many cases it is much lower.

Abstract: A method of modifying a series of packets of a content for transmitting to a user over a network includes providing a key that includes at least one aspect of at least one of the packets of a content that is to be modified; and modifying the content based on the key to thereby provide a modified content. A method of rendering a series of packets of a content and a system for modifying a series of packets of a content for rendering by a user are also presented.
