摘要:
Analysis of a seismic event, such as a microseismic event caused by hydraulic fracturing, comprises measuring seismic waves emitted by the event and converting the measurements into two values for magnitude of explosion or implosion and for magnitude of displacement discontinuity at a plane, together with two directions, a direction of a normal to the plane and a direction of displacement; where the two values and the two directions compose the moment tensor describing the seismic event. The measurements may be converted into the moment tensor and decomposed into the values and directions. The values and directions associated with several seismic events may be displayed concurrently on a graphic display as a graphic representation of multiple events, where each event may be depicted with magnitude of expansion or contraction represented by a volume and the plane represented as a laminar object.

Free-hand manual navigation assists diagnosis using perspective rendering for three or four dimensional imaging. In addition to a three-dimensional rendering for navigation, a number of two-dimensional images corresponding to a virtual camera location are displayed to assist the navigation and visualization. Alternatively or additionally, a representation of the virtual camera is displayed in one or more two-dimensional images. The virtual camera is moved within the two-dimensional images to navigate for perspective rendering.

The present invention relates to a manually operable input apparatus (202) for a portable electronic processing device (102), such as a mobile phone or hand-held processor. The apparatus defines a plurality of regions (303, 304) each representing a respective data item and comprises a plurality of sheets configured to produce a response to a mechanical interaction. Furthermore, the sheets are configured to be wrapped around the device to provide a protective cover.

Data processing apparatus (101 and 102) configured to receive signals from an input sensor (106) arranged to duplicate or replace operations of a keyboard, in which the signals correspond to positions of mechanical interactions with the sensor (106). The apparatus comprises processing means (1202) configured to process data derived from the input sensor including positional data corresponding to the position of a mechanical interaction with said input sensor (106) and a second data type corresponding to the absence of a mechanical interaction with said input sensor. The processing means (1202) is configured to generate data representing a first character in response to processing an item of data of said second type followed by positional data corresponding to a first position, and to generate data representing a different second character in response to processing positional data corresponding to a different second position followed by an item of data of said second type.

An apparatus is disclosed for supplying input signals to a computer. A sensor having the form of a sphere has a touch sensitive surface for generating position data for touch events. The sensor includes orientation sensors that determine rotation with respect to the earth's magnetic and gravitational fields. Orientation data may be combined with position data to interpret the orientation of touch events on the surface with respect to the computer's display. Cursor movement or text may be generated from touch events. Preferably the sphere has a roughened surface that generates sound when touched. Position data is generated by processing signals from microphones under the sphere's surface.

A system for raising a person lying on the ground includes a lifting seat 10 comprising a back rest 12 coupled to a seat portion 18. At either side of the back rest 12 and seat portion 18 there are provided side supports 14, 16, 20 and 22. The system is such that in use it can be slid onto a person lying on his/her side, rotated such that the back rest 12 lies on the ground, with the supports 14-22 supporting the person during rotation to a back-lying position. The back rest 12 can then be rotated upwardly to bring the person into a sitting position.
摘要:
In a diagnostic ultrasound imaging system, a sequence of more than two signals is transmitted into the interrogation of the patient's body. In one embodiment of the invention, the pulses are grouped as pairs that have an inverted phase, that is, one is time-domain negative of the other. In an alternative of this embodiment, the pulses need not be paired, but rather are generated with alternating phase characteristics. The return signals are then filtered to isolate (or suppress) return signal components corresponding to portions of the interrogation region with non-linear (or linear) response characteristics. In a second embodiment of the invention, three or more pulses are generated so that have non-equidistant relative phase distribution. By combining the return signals, linear return signal components are suppressed.
