An apparatus for a virtual turntable system for computer generated broadcast video streams for a multiple product sales display. The virtual turntable system collects data, including images and status information, and generates a video stream for presenting product information sequentially on a video monitor. In one embodiment, the virtual turntable system reads the data, including the turntable list, formats and updates the data, and then outputs the data in a video stream. In one embodiment, the virtual turntable system includes a data storage device for storing the data for the virtual turntable system, a computer system for accessing the data and creating item containers for the items on the current item list that are to be displayed on a monitor, and a video imager for creating a video stream for displaying a plurality of current items in a rotating or other sequential manner.

A water dispenser assembly used for a dispensing system includes an inlet configured to receive water from a water supply, and a flow meter in communication with the inlet. The flow meter is configured to measure an amount of water passing therethrough. A first valve is arranged in communication with the flow meter, and the first valve is configured to enable and restrict water flow to an outlet. A controller is operatively coupled to the flow meter and the first valve. The controller is configured to control the dispensing of water based on the measured amount of water passing through the flow meter and based upon a volume error factor correction.

A portable wireless tracking device that uses radio-frequency identification (RFID) technology to monitor the location and physical condition of emergency personnel at the scene of an emergency incident. RFID technology uses radio-transmitting interrogators to send out radio waves to preprogrammed receiver computer chips which respond to the radio query with another radio signal. If the frequency is not correct, the receiver or interrogator will not recognize it. The invention also uses wireless remote stations that are placed in high rise buildings or other large commercial or infrastructure locations to provide facility managers and emergency responders with a reliable wireless emergency management and communications system. The remote stations can include broadband video, audio, two-way radio, as well as chemical and air flow data from life safety devices that can be used to monitor, direct, communicate and share with public safety agencies.

An office chair is provided having a contoured back assembly comprising a back frame and a suspension fabric. The fabric is attached to the back frame about its periphery wherein the back frame has a three-dimensional contoured shape formed by overlapped frame rings with the fabric being joined thereto. The fabric is secured to the frame by a machine wherein the fabric is first stretched from the outer edge of the fabric and then is clamped by a front frame section in the pre-tensioned or pre-streched condition. The fabric edges are allowed to hang loose and then fixed in the front frame section. Once secured, the fabric is unclamped from the front frame section, and then this sub-assembly is affixed to the rear frame ring to complete the assembly of the back frame.

An interconnection structure for interconnecting circuitry on a first conductive layer to circuitry on a second conductive layer is provided. The interconnection structure of the present invention comprises a signal conductor via surrounded by a plurality of ground vias. The plurality of ground vias shield the signal conductor via, thus providing electrical isolation for the conductor via from the rest of the circuitry. One feature of the present invention is that the plurality of ground vias can be modified, adjusting their diameters and their placement relative to the signal conductor via, in order to affect the overall characteristic impedance of the interconnection structure. This feature is useful when propagating high frequency signals between signal traces on different conductive layers of a printed circuit board. In view of the high frequencies used in today's wireless communication systems, the interconnection structure proposed aids in the practical implementation of radio frequency modules by mitigating the effects of impedance discontinuities ordinarily present at signal trace-to-via transition regions.

In one embodiment of the present invention there is provided a method of deploying within a lumen a filter having a material capture structure and a support structure by positioning the filter within the wall of a lumen; and deploying the filter into contact with the lumen by placing the material capture structure across the lumen flow path as one support structure element extends in a clockwise manner along the lumen wall and another support structure element extends in a counter clockwise manner along the lumen wall. In another embodiment of the present invention there is provided a method of positioning within a lumen a filtering device having a filter and a filter support structure by advancing the filtering device along the lumen while the filter and the filter support structure are in a stowed configuration; releasing the filter and the filter support structure from the stowed configuration so that opposing spiral elements of the filter support structure are in atraumatic contact with the lumen and the filter is positioned across the lumen flow path. In another embodiment of the present invention there is provided a method of deploying and retrieving a filter within a vessel by deploying the filter into the vessel from a delivery sheath having a first diameter; and retrieving the filter using a recovery sheath having a second diameter no more than 2 Fr larger than the first diameter.

In one embodiment of the present invention there is provided a method of positioning a filter within a lumen by positioning a filter within a lumen by exerting a radial force generated by a support structure against the lumen while suspending a material capture structure between opposing members of the support structure; and self adjusting the length of the filter support structure along the lumen wall in response to a change in the size of the lumen. In another embodiment of the present invention there is provided a method of providing protection during a procedure performed in the vasculature by placing an open loop device within a vessel down stream of a location in the vasculature; performing a procedure to treat the vasculature in proximity to the location; and capturing debris released during the procedure in a material capture structure suspended across the vessel and supported by the open loop device.
