Abstract: Techniques are presented for identifying mobile devices within a coverage region of a wireless station. Positions for mobile devices, if any, within the coverage region are determined. It is then determined whether the positions are within one or more defined areas, called “notification areas” herein. Additionally, selected mobile devices within notification areas are sent messages. The selected mobile devices are selected via certain criteria, including, for instance, campaign specifications and subscriber information. A message can be sent to a mobile device if the subscriber corresponding to the mobile device has indicated an acceptance of a category of notifications for the message and for the publisher who is publishing the notifications. The category could be traffic conditions and the publisher could be a Department of Transportation having responsibility for a particular freeway. These are two examples of multiple criteria for selecting mobile devices to which messages could be sent.

Abstract: A method for prediction of groundwater level fluctuation. This approach involves using groundwater observations for the determination of rate of decline due to infiltration and rate of rise dues to precipitation for the groundwater level at a site, followed by use of those rates with historic precipitation records to estimate the extent of historic saturation and inundation periods at the site. This information can then be used as an objective criterion for the delineation of jurisdictional wetlands and other similar applications.

Abstract: The invention is a process for the development and use of a model for the prediction of shallow ground water level fluctuation. This approach involves using site specific ground water observations for the determination of rate of decline due to infiltration and rate of rise due to precipitation for the ground water level at a site, followed by use of those rates with historic precipitation records to estimate the extent of historic saturation and inundation periods at the site. That information may then be used for the delineation of jurisdictional wetlands and other similar applications. The steps of the process are as follows: 1. Short-term on-site observations of ground water level and rainfall 2. Statistical analysis to determine rainfall response and infiltration rates to develop site model 3. Prediction of past ground water levels using historic rainfall records for the region 4.

Abstract: It is determined whether a location of a mobile device is within a coverage region of a first information service. Communications for the first information service are redirected to a second information service when the location of the mobile device is not within a coverage region of the first information service. The second information service generally has a coverage region encompassing the location of the mobile device. Communications between a mobile device and a first information service are redirected to another information service when properties of the new information service are determined to meet predetermined criteria set by a user of the mobile device, by an application, or both. In yet another aspect of the invention, Replacement of information services can be “aggressive” or “non-aggressive.” Communications between a mobile device and an original information service are redirected to another information service when the original information service fails.

Abstract: The present invention provides methods and apparatus to distinguish and/or separate an object from a background. The methods use backgrounds of known and/or advantageous texture. In an embodiment, a measure of image texture, namely the spatial frequency is used to distinguish and/or separate an object from its background. The use of image texture overcomes limitations of chroma keying used as a processing technique in photography for object-background separation. This is useful in the separation of image pixels belonging to the object of interest from image pixels belonging to the background.

Abstract: This invention provides methods, apparatus, system, and article of manufacture which solve the problem of mismatch between the keywords employed by a user in making a query and those assigned by the manual or automatic classification system stored in the system's keyword index. The system records the initial keyword(s) input by the user and holds them until the user is either satisfied or gives up. If in a query session the user is satisfied with the object(s) retrieved from the repository, the system associates the initial keywords(s) with the retrieved object(s). This facilitates the object's retrieval by the same user or subsequent users who input the same keywords. The keyword index is modified directly when, for example, a single service or application controls the interaction between user and repository, end to end.

Abstract: A method, apparatus, and computer implemented instructions for managing bookmarks. In response to detecting a service domain with a dynamic bookmark service, a client device sends a request containing criteria identifying a dynamic bookmark to the service domain. In these examples, the dynamic bookmark contains attributes or criteria that may be used to bind or locate regular bookmarks having similar attributes or criteria. The request is received by a server, which queries a data structure using the criteria for a bookmark, corresponding to or matching the criteria, to generate a result. This result is returned in a response to the client. The client processes any bookmarks received in the response, wherein any bookmarks returned in the request are bookmarks matching the dynamic bookmark.

Abstract: An electric guitar has an electromagnetic resonating unit (3) which is arranged to resonate the strings (2) of the guitar, either individually or together. The resonance of each string is picked up by a pick-up unit (4), and the frequency of resonation of the string is detected and compared with a desired value. A tension adjusting unit (5) adjusts the tension in each string (2) until the frequency of resonance of the string correponds to the desired frequency, in order to tune the guitar to a desired tuning pattern. A control panel (6) on the body (1) of the guitar displays optional tuning patterns which may be selected by a user. Automatic tuning of the guitar may be achieved, without requiring the strings to be plucked manually.

Abstract: A double quill-like, security mechanism having a pair of concentric, hollow cylinders, one positioned to rotate wholly within the other and restricted against axial displacement thereby to provide means for supporting a rotatable gate structure carried by the outer cylinder against removal therefrom except at a predetermined angular relationship of rotation between the two cylinders.

Abstract: A portable self-powered electrically conductively isolated device converts alphanumeric electric signals transmitted from a Touch-Tone telephone at a sending station to visual signals at a receiving telephone station. A magnetic pickup is attached to the activated receiving telephone, as by a suction cup, and feeds two-frequency Touch-Tone signals to tuned detectors which energize two overlapped parallel-busbar grids interconnected at their crossover points by panel-displayed light-emitting diodes. By code the touch-sent signals are converted to visually received signals; for example, on pushbutton 5 one touch means "J", two touches "K" and three touches"L".

Abstract: A clamping mechanism for receiving the free end of a swinging gate or the like including a pair of pivoted, clam-like arms, carried by a pedestal capable of being mounted upon a hollow cylindrical support via an expandible sleeve forming a part of the pedestal, the aforesaid arms being U-shaped in cross section with the open sides facing in such a manner that when closed only an opening formed by their ends is accessible to admit the aforementioned gate end. A locking mechanism is provided internal of the arms.
