Abstract: Disclosed is a valve assembly operable to selectively control a flow or passage of a fluid. The valve assembly may be applied to any appropriate mechanism such as a hydrocephalus shunt, fluid draining sewage system, or tank holding system. The valve assembly disclosed may include a selected profile for various applications.

Abstract: An implantable medical device is disclosed that includes a valve seat and a valve member movable with respect to the valve seat. An adjustment circuit assembly includes a resistive element that is coupled to the valve member and operable to position the valve member relative to the valve seat so as to alter the pressure setting in response to a current applied to the resistive element.

Abstract: Embodiments are directed towards providing a computer-implemented method for integrating or placing branded product advertisement within media, including maintaining by a placement server a database of placement opportunities, receiving from a buyer computer a media plan by a buyer, the media plan specifying desired placements to purchase and a budget, projecting the number of impressions the purchased placements will generate, initiating execution of the media plan, gathering data about the results of each of the purchased and produced placements, determining a placement quality ranking for each placement and estimating a media value for each placement.

Abstract: Methods for covalently binding a silicone polymer to hair or nails using UV light, a catalyst, a reactive solution, and compositions related thereto. The methods can include synthesizing a photo-reactive silicone and bonding the photo-reactive silicone polymer to hair, nails, or keratin. The methods can also include applying a vinyl-containing silicone polymer and a catalyst, or an aldehyde functionalized silicone polymer and reactive composition, to covalently bond the silicone polymer to hair, nails, or keratin. An advantage of covalently bonding silicone polymer to hair or nails can be that the silicone polymer add strengthens and shine to hair and nails, but are more resistant to washings with soap and shampoo than non-covalently bound silicone polymers.

Abstract: A stylet having a non-round cross-sectional shape which is specifically adapted to reduce the adhesion or “stickiness” of contact between the stylet and the interior surface of the lumen of an elastomeric catheter through which it extends. The stylet may be “pre-loaded” into the catheter.

Abstract: A current-regulating driver circuit for a light emitting diode (LED) maintains energization drive to and thereby illumination provided by the LED at a prescribed, substantially constant value, over a relatively wide range of input (AC or DC) voltage. First and second input nodes are coupled to a source of AC or DC voltage and to a load, powered by the source of AC or DC voltage. An input rectifying diode is coupled to the first input node. A controlled current flow element is coupled in a first current flow path between the input rectifying diode and the LED and is controllably operative to supply current for illuminating the LED.

Abstract: A dual solid state switch architecture has a plurality of control/monitor ports, selected ones of which are used to-control the operation of a pair of power MOSFETs current flow paths through which are coupled to prescribed ones of a plurality of input/output ports that are adapted to be coupled to a circuit path containing a load and either and AC or DC power source therefor. Selected others of the control/monitor ports are used to monitor current delivered to the load. A leakage current by-pass resistor is connected between selected input/output ports, to which a neon tube may be connected for indicating the switching on of an AC source. This resistor serves to provide a bypass path for leakage current through the MOSFETs, so as to prevent the neon tube from being erroneously illuminated, when the MOSFETs have been turned off.
