Remotely actuated robotic wrist for applications in the field of teleoperation, for example for mininvasive surgical operations, comprising a distal element (3) mounted on a support (2) capable instantaneously to rotate with respect to a fixed member (5), for example by a ball joint (10) that allows three rotational degrees of freedom. In particular, the support (2) can be oriented with respect to the fixed member (5) with a redundant actuating system by arranging four forces in eccentric points, for example by means of tendons (8), and causing the rotation of the support (2) about the central post (5) by the ball joint (10). Alternatively, the support (2) can be oriented with respect to the fixed member (5) by a mechanism that reproduces the rolling of a mobile sphere, which belongs to the support, on a fixed sphere, integral to the fixed member.

The present invention provides a comprehensive method to design an automatic media viewership measurement system, from the problem of sensor placement for an effective sampling of the viewership to the method of extrapolating spatially sampled viewership data. The system elements that affect the viewership—site, display, crowd, and audience—are identified first. The site-viewership analysis derives some of the crucial elements in determining an effective data sampling plan: visibility, occupancy, and viewership relevancy. The viewership sampling map is computed based on the visibility map, the occupancy map, and the viewership relevancy map; the viewership measurement sensors are placed so that the sensor coverage maximizes the viewership sampling map. The crowd-viewership analysis derives a model of the viewership in relation to the system parameters so that the viewership extrapolation can effectively adapt to the time-changing spatial distribution of the viewership; the step identifies crowd dynamics, and its invariant features as the crucial elements that extract the influence of the site, display, and the crowd to the temporal changes of viewership. The extrapolation map is formulated around these quantities, so that the site-wide viewership can be effectively estimated from the sampled viewership measurement.

The present invention relates to a tibial prosthesis having an articulating component and a tray component. The articulating component is configured for attachment to the tray component. Additionally, the articulating component may be attached to the tray component in a first condition in which the articulating component is at least rotatable relative to the tray component. This allows for the tray component to be attached to the tibia in a position that provides for proper rotation of the tray component with respect to the tibia and/or prevents the tray component from overhanging the resected tibia. Then, the articulating component may be rotated and/or translated to a position that provides for proper alignment of the articulating component with a femoral prosthesis. Once in this positioned, a locking mechanism is used to rotationally fix the articulating component to the tray component.

The present invention is directed to devices and methods in which one or more miniature synthetic jet actuators are integrated with a chemical fluidic sensor (ChemFET) to effect inhalation and exhalation of ambient gas samples and induce small scale mixing at the surface of the sensor. The fluidically integrated jet transports ambient gas or liquid into the jet/sensor assembly through integrated gas or liquid channels, impinges the sample gas or liquid on the sensing element, and finally ejects the sample gas or liquid back into the ambient gas or liquid. The response of the sensor in the presence of the active jet is compared to its response when the jet is inactive. The jet actuator directs entrained ambient gas or liquid toward the active surface of the sensor, and the impingement of sample gas or liquid onto the surface of the sensor results in faster response time. Other embodiments are also claimed and described.

A downhole acoustic measurement tool includes at least one transmitter longitudinally spaced apart from a non-uniformly spaced longitudinal array of acoustic receivers. The array has a non-uniform spacing such that a first spacing between a first pair of consecutive acoustic receivers in the array is not equal to a second spacing between a second pair of consecutive acoustic receivers in the array. Non-uniform spacing of the receivers in the array reduces aliasing when the received waveforms are processed, for example, to obtain semblance data.
