Abstract: The dielectric constant and loss tangent of a transmission structure is lowered by sandwiching a conductor between two dielectric structures one or both of which have a series of openings. The conductor is formed so that the conductor is formed across each opening of each dielectric structure. The dielectric structures provide structural support while exposing a significant portion of the conductor to air, thereby forming a transmission structure with an largely air-dielectric.

Abstract: An intravascular catheter system for the treatment of occluded blood vessels that includes tissue displacement or hinged expansion members that are movable from a closed to an open position. An actuating assembly may be provided for moving the tissue expansion members between an open and closed position to exert a substantially lateral distal end force upon the region surrounding an occluded blood vessel. The tissue expansion members may stretch apart, tear or otherwise disrupt a vascular occlusion sufficiently to create a pathway that may support the passage or placement of a guidewire or an interventional vascular device across the occlusion or obstruction. Methods of crossing or displacing a vascular occlusion are further provided that include the positioning of a vascular catheter having at least one hinged spreading member positioned at the distal region of the catheter that is responsive to directed force along the longitudinal axis of the catheter.

Abstract: Presented is a method and system for visually depicting performance levels in a time-varying environment such as a workplace experiencing time-varied workloads. A call center is one example of such a workplace. One embodiment includes a graphical depiction with a reference time period, such as a work day, on a the horizontal axis. A vertical axis displays, for example, the length of time an incoming call must wait before being answered. As calls come into the call center a symbol is placed horizontally on the graph corresponding to the time during the reference time period that the call was received, and vertically according to the time the caller had to wait before a call center agent answered the call. Other information may also be superimposed on the graph, such as a call center service metric, and abandoned calls.

Abstract: A ternary content addressable memory (CAM) cell includes a dynamic random access memory (DRAM) cell storing data values and a DRAM cell storing mask values. The mask values control a masking circuit. The CAM cell also includes a compare circuit coupled among the DRAM cell and the masking circuit. The compare circuit of an embodiment receives data and comparand data and affects a logical state of a match line in response to a predetermined relationship between the data and comparand data. The compare circuit includes a first pair of transistors coupled for conduction state control by the comparand data and a second pair of transistors coupled for conduction state control by the data. The first pair of transistors includes two n-channel transistors. The second pair of transistors includes one n-channel and one p-channel transistor. A sense amplifier couples to the match line to detect changes in match line logical state.

Abstract: A GPS receiver system determines the presence of trackable signals at code delays less than the prompt delay being tracked for a particular signal and changes the prompt delay to correspond to the smallest code delay having a trackable signal. Trackable signals at large code delays are multipath signals and may be separately tracked to aid in dead reckoning. The trackable signals at code delays not adjacent to the current tracked prompt delay may be tracked in the same channel as the prompt delay so that all satellite channels are continuously evaluated for multipath signals being tracked or a non-satellite specific channel may be used to sequentially step through the satellite signals to evaluate multipath on a satellite by satellite basis.

Abstract: A content addressable memory (CAM) device having a data CAM array and an error CAM array. The data CAM array is provided to store data words, compare the data words with a comparand value, and, if one of the data words matches the comparand value, assert a match signal that corresponds to the matching data word. A priority encoder responds to the match signal by outputting a match address that corresponds to the matching data word. The error CAM array is provided to store at least one error address value and is coupled to the priority encoder to receive the match address. The error CAM array compares the match address with the error address value and asserts a match error signal if the match address matches the error address value.

Abstract: A terrestrial C/A code GPS receiver system digitally samples, filters and stores a segment of 11 half chips of the received composite as a binary number and multiplexes this number for parallel correlation with each of a series of multibit code replicas for the satellites to be tracked. Each of the time delay specific correlation products are accumulated in a cell of a memory matrix so that at least twenty two delays for each satellite may be evaluated each code period providing fast reacquisition, even within a city intersection, as well as correction of multipath tracking and multipath interference. All cells of the memory matrix may be used for an acquisition of a single satellite in about 4 ms. Two satellite tracking, in addition to altitude hold, uses cross track hold alternating with clock hold to update the cross track estimate. Single satellite tracking uses cross track and clock hold together. Navigation data is updated with detected changes in motion including turns.

Abstract: Total occlusions are crossed by passing a guidewire or other penetrating wire from a point proximal to the occlusion into a subintimal space between the intimal layer and adventitial layer of the blood vessel wall. The wire is advanced to a point distal to the occlusion and thereafter deflected back into the blood vessel lumen, typically using a deflecting catheter which is advanced over the guidewire after it has been positioned within the subintimal space. After the guidewire is returned to the blood vessel lumen, the deflecting catheter may be withdrawn and the guidewire is available for introduction of other interventional and diagnostic catheters.

Abstract: A data detection circuit within a global positioning system (GPS) satellite receiver operates to detect and decode data sent in a spread spectrum signal. The data detection circuit receives input from a radio receiver, the information containing data from a plurality of satellites. The data is supplied to a circular memory device, which determines which data corresponds to which satellite. The memory device sends the received signal to a matched filter, which decodes the signal received from each satellite. This signal is analyzed to determine whether a phase inversion due to data modulation on the received signal is present. The phase inversion can occur at boundaries, known as data epochs, in the received signal, and corresponds to data in the received signal. This data contains information relating to the position of each satellite and is collected by the data detection circuit for use by the GPS receiver.

The block selection circuit includes an input to receive a class code and circuitry to output a plurality of select signals to the plurality of CAM blocks. Each of the select signals selectively disables a respective one of the plurality of CAM blocks from participating in a compare operation according to whether the class code matches a class assignment of the CAM block.
