Abstract: Methods, systems and devices are described for a direct-sequence spread-spectrum communication scheme that increases the number of users by utilizing a plurality of closely spaced orthogonal carriers that produce overlapping spectra. A method includes overlapping a plurality of direct-sequence spread-spectrum signals using carrier frequencies that are orthogonally spaced relative to a bit rate. The methods, systems and devices provide advantages because they can accommodate an increase in the number of normalized users and can optimize the loading of users across multiple frequency channels.

Abstract: A method for re-selecting control channels in a mobile station reduces the use of resources by limiting an evaluation of candidate control channels to those channels which satisfy certain criteria and are deemed to be eligible control channels. As a consequence, resources are not spent on attempting to re-select a control channel that is not compatible with the mobile station.

Abstract: A system and method of maintaining a desired additive to water ration in a fire-fighting system including a water flow sensor configured to measure the water flow rate, a water pump, a hydraulic pump, a linear hydraulic cylinder driven by the hydraulic pump, an additive pump mechanically coupled to the linear hydraulic cylinder; and a pump displacement sensor configured to sense the position of the additive pump, the pump displacement sensor being in communication with the water flow sensor to maintain a pre-determined ratio of additive to water.

Abstract: A system and method are disclosed which allow a user to capture and manage information for later review without interrupting the user's current activity, such as browsing the web, viewing streaming media, or operating a mobile computing device while traveling. The system includes a user interface, a local database application, and: a web browser and web browser plug-in, a streaming media server and streaming media player application, or a GPS unit. The method for capturing information while using a web browser or a streaming media player application includes the steps of selecting an object, obtaining local origination data, and storing the object and local origination data. The method for capturing information while using a mobile computing device having GPS capability includes activating a GPS capture function, obtaining local origination data, storing GPS objects and local origination data, and generating an index to geographically relevant objects.

Abstract: An implant is provided which facilitates enhanced structural stability across a joint to be immobilized. The sacroiliac implant is an elongate structure having two cylindrical sections of differing diameters. The implant further has like-handed, but dissimilar pitched threaded sections at the proximal and distal ends thereof to produce compressive forces across the joint. A hollow core traverses the length of the implant. A plurality of apertures or openings are formed through the implant transversely to the longitudinal axis and communicate with the hollow core. Bone graft or a BMP-soaked carrier fill the hollow core. The openings or apertures provide a conductive path of healing for bony ingrowth. The proximal end of the implant provides for engagement with a tool to drive the implant.

Abstract: A method for sensing and analyzing data with surface acoustic wave (SAW) devices comprises the steps of: propagating a sampling signal at a fundamental frequency through a SAW device coated for selective adsorption; measuring at least one parameter of at least one higher order harmonic of the fundamental frequency sampling signal; exposing the coated SAW device to enable the selective adsorption; measuring the at least one parameter of the at least one higher order harmonic of the fundamental frequency sampling signal after the exposing step; comparing the measurements of the at least one parameter of the at least one higher order harmonic before and after the exposing step; and, deriving a result of the selective adsorption based upon the comparing step. The at least one parameter is harmonic power and harmonic frequency. The at least one higher order harmonic is one or more odd harmonics.

Abstract: The system of the present invention provides physical access control for storage media in stand-alone workstations which are processing classified or unclassified sensitive information. The system protects the workstation media from theft, tampering and from observation of the monitor by passers-by. The system, when invoked, presents an alarmed-state security screen, allows only passwords to be entered from the keyboard, and protects writable media from access or removal. An alarm sounds if (a) any drives (both internal and external) containing writable media are opened or removed, (b) the program is interrupted, (c) too many invalid password characters are entered, or (d) the power is interrupted.

Abstract: A circuit for converting RGB to composite video. The circuit is particularly useful in a video overlay application. Notch filters are used both in the video path and keying path. The notch filters are centered at frequenices equal to the dot clock frequency of the RGB divided by integers where the result of this division falls within the chroma subcarrier spectrum.

Abstract: A circuit which receives RGB and composite video and provides both RGB and composite merged outputs. Merging of RGB signals occur where the input composite signal is converted to RGB; and also, merging occurs of composite signals where the input RGB is converted to a composite signal. The circuit is particularly useful in a video overlay application. Notch filters are used both in the video path and keying path. The notch filters are centered at frequencies equal to the dot clock frequency of the RGB divided by integers where the result of this division falls within the chroma subcarrier spectrum.
