Abstract: A method for color bar codes includes selecting N bar code colors for a color bar code system to be generally distinct from each other given the range of colors that a camera reader is expected to produce given at least one environmental condition in which the camera reader is expected to operate.

Abstract: A trocar assembly including a low-profile retractable shield deployable adjacent to a cutting element with a cross-sectional area which is small relative to the total cross-section of the assembly.

Abstract: A method for correlating behavior between two elements of a system to determine the presence of mutual interaction between the elements, the method including measuring the behavior of two elements of a system over time with respect to mutual interaction, thereby producing two behavior functions, expressing a plurality of constraints on a theoretical distance c between the behavior functions, and determining that the elements are behaving as mutually interacting elements where there exists an actual distance c satisfies the constraints.

Abstract: A vehicle, including a vehicle frame, a duct carried by the vehicle frame with the longitudinal axis of the duct perpendicular to the longitudinal axis of the vehicle frame, a propeller rotatably mounted within the duct about the longitudinal axis of the duct to force an ambient fluid therethrough from its inlet at the upper end of the duct through its exit at the lower end of the duct, and thereby to produce an upward lift force applied to the vehicle, and a plurality of parallel, spaced vanes pivotally mounted to and across the inlet end of the duct about pivotal axes perpendicular to the longitudinal axis of the duct and substantially parallel to the longitudinal axis of the vehicle frame, the vanes being selectively pivotal about their axes to produce a desired horizontal force component to the lift force applied to the vehicle.

Abstract: A differential-pressure flow sensor for airflow measurement in the presence of water condensation, for use with mechanical ventilators. The pressure-sensing ports at either end of the interfering body are displaced from the inner surface of the surrounding tubing, so as to prevent obstruction of the pressure-sensing ports by free flowing condensed water. The leading edge of the interfering body is angulated so as to deflect airflow towards the pressure-sensing port on the trailing edge of the interfering body, thereby flushing water droplets away from the port. The sides of the interfering body are sloped so as to generate turbulent boundary layer airflow at areas distant from the pressure-sensing ports, thereby encouraging water condensation away from the ports.

Abstract: A system and methodology for tracking objects including affixing at least one imagable identifier onto each of a multiplicity of objects to be tracked, imaging at least a portion of at least one of the multiplicity of objects at a known location to provide an at least partial image of the at least one of the multiplicity of objects, containing the at least one imagable identifier and employing the at least partial image of the object containing the at least one imagable identifier to provide an output indication of the location of the at least one of the multiplicity of objects.

Abstract: A communication system includes a plurality of subscribers having a telephone set and different types of home modems coupled using twisted pairs to a local server that includes a plurality of downstream repeaters, a central office coupled to a local server using twisted pair subscriber lines. The central office includes a telephone switch that provides telephone service to the subscribers and a concentrator that connects a plurality of upstream repeaters with a number of office modems that provide data service to the subscriber. A communication system uses CAP or DMT line signals with time division. The line signal transmits with different time framing. Every subscriber line can work in one of three operation modes Asymmetrical mode, Half-Asymmetrical mode, and Symmetrical mode.

Abstract: A method and apparatus for registering unanswered telephone calls is provided. The method includes directing the unanswered call to an external server, recording details of the calling telephone, including the telephone number of the calling telephone (caller ID), the time and the date of the call, and notifying the called telephone of the details of the unanswered telephone call.

Abstract: A multimodality imaging system including a plurality of imaging systems, and at least one rail upon which at least one of the imaging systems is slidingly mounted.

Abstract: A decision operation tree (“DO Tree”) according to the present invention is a logical tree representation of decision making rules and actions instituted according to those rules. In preferred embodiments of the invention, one or more DO Trees are tailored to serve a user's rating and billing system needs. According to the present invention, Do Trees are comprised of a plurality of nodes and branches, which branches connect the nodes together in a descending relationship. Any node may have defined for it one or more actions (whose implementation can be prioritized or ordered) which are triggered whenever the node is reached. Those nodes having branches stemming (“descending”) from them have two parameters, a Decision Attribute and a Branching Type, which defines the node's relationship with its descending branches. Upon occurrence of the predefined event, the method includes proceeds from node to node, and optionally performs one or more actions in each node.

Abstract: A printed circuit board antenna is a diversity polarization antenna for connecting with a printed circuit board. The antenna includes a fixed height connector, a horizontally polarized antenna, and a vertically polarized antenna. The phase center of the vertically polarized antenna coincides with the phase center of the horizontally polarized antenna.

Abstract: A method for identifying a longest common substring for a string T and a string R, including selecting a registration symbol that appears in both strings R and T, constructing a first relative distance vector R′ from the appearance of the registration symbol in the string R, constructing a second relative distance vector T′ from the appearance of the registration symbol in the string T, deriving a substring pair RCS and TCS in the strings R and T respectively for each common substring pair RCS and TCS in the vectors R′ and T′ respectively, and identifying the longest matching of the RCS and TCS substring pairs as the longest common substring for the string T and the string R.
