A computer-implemented matching service matches users to other users, and/or to user communities, based at least in part on a computer analysis of event data reflective of user behaviors. The event data may, for example, evidence user affinities for particular items represented in an electronic catalog, such as book titles, music titles, movie titles, and/or other types of items that tend to reflect the traits of users. Event data reflective of other types of user actions, such as item-detail-page viewing events, browse node visits, search query submissions, and/or web browsing patterns may additionally or alternatively be considered. By taking such event data into consideration, the matching service reduces the burden on users to explicitly supply personal profile information, and reduces poor results caused by exaggerations and other inaccuracies in such profile information.

Materials and methods for identifying unique sites in bacterial 16S and 23S rDNA are provided, as well as specific unique sequences of 16S rDNA in select bacteria. The distinguishing moieties will enable rapid differentiation between families, genera, groups, species, strains, subspecies, and isolates of microorganisms. Such differentiation can be performed by using rapid screening kits in combination with in silico analysis for diagnostic, prognastic, epidemiologic, phylogenetic, and other purposes.

Computer analysis is made of individual patient related data in order to select standard or pre-manufactured orthodontic appliances or appliance components (10) that are most likely to provide orthodontic treatment suitable for the individual patient. This analysis can be made by the software of a custom orthodontic appliance designing system, without actually manufacturing the custom appliance. Geometric parameters (21-24, 28, 29) of a custom designed appliance may be compared with corresponding parameters of alternative standard appliances or appliance components so that the closest standard component can be used. The custom appliance can be designed to accommodate the geometries of one or more appliance components. Where custom mounting instructions that modify otherwise standard installation of an appliance or component will render the standard component more compatible with a custom appliance design, such instructions are provided to the orthodontist along with the selection. The invention is most useful in selecting orthodontic brackets, or combinations of standard brackets and standard archwires.

A torsion beam suspension member using two u-shaped, stamped members that are superimposed and welded to form a torsion arm. No additional torsion tube or bar is needed. Tuning holes (rectangular, oblong, round or any other suitable shape) are used to change or tune the torsional resilience of the suspension. In the preferred embodiment, the tuning holes are oblong and located near the center of the cross member. The tuning holes are selected based on having target value for torsional compliance or resilience. The size, quantity and location of the tuning hole are chosen based on computer analysis. An optimization or iterative process is used to arrive at the final hole size, quantity and location.

A plurality of modules interact to form an adaptive network in which each module transmits and receives data signals indicative of proximity of objects. A central computer accumulates the data produced or received and relayed by each module for analyzing proximity responses to transmit through the adaptive network control signals to a selectively-addressed module to respond to computer analyses of the data accumulated from modules forming the adaptive network. Interactions of local processors in modules that sense an intrusion determine the location and path of movements of the intruding object and control cameras in the modules to retrieve video images of the intruding object. Multiple operational frequencies in adaptive networks permit expansions by additional networks that each operate at separate radio frequencies to avoid overlapping interaction. Additional modules may be introduced into operating networks without knowing the operating frequency at the time of introduction. Remote modules operating as leaf nodes of the adaptive network actively adapt to changed network conditions upon awaking from power-conserving sleep mode. New programs are distributed to all or selected modules under control of the base station.

Method and device is proposed herein for unattended detection of deliberate or unintentional breaches caused by an operator of a routinely executed procedure comprising transference of objects and their mandatory presenting to the item-sensing device for registration or testing or classification. The invention can be used for detecting fraud of a cashier in checkout retail environments by omitting registration of items placed on the take-away belt. The invention is based on detecting motion and presence events in the predetermined workspace areas and comparing their temporal sequence with the predetermined scenarios. In the case of coincidence with the scenario, the sensing device signal in the due time is checked to be received. In the case of a wrong or no signal received, the procedure is recognized as incorrectly executed. Motion and presence events are detected by computer analysis of live video from the camera and/or by applying the motion and the presence detectors.

A game ball delivery apparatus that adjusts the delivery of game balls to the actual practice needs of the player returning the delivered game balls, based on a computer analysis of player performance data, including but not limited to data collected from inertial and physiological sensors. The parameters of delivery, such as trajectory, speed, and interval of successive balls, are modified in real-time, as the player is training. One or more highly miniaturized sensors for collecting performance data are worn by the player without affecting the player's motions. A computer capable of analyzing said sensor data, selects delivery parameters for subsequently delivered balls, and transmits said delivery parameters to the ball ejector controller. Further, the system may optionally include a means for generating a feedback signal to the player to indicate deviations of the measured motion of the player from reference performances of the motion.
