Abstract:
Method for controlling continuum robots and systems therefrom are provided. In the system and method, a new system of equations is provided for controlling a shape of the elastic member and a tension on a tendon applying a force to an elastic member of the robot. The system of equations can be used to estimate a resulting shape of the elastic member from the tension applied to the tendon. The system of equations can also be used to estimate a necessary tension for the tendon to achieve a target shape.
Abstract:
The present invention relates to airport advertising. Airports are divided into the “landside” to which the general public is permitted and which includes the terminal(s), car parks etc., and the “airside” from which the public is excluded and which includes the runways, taxiing area, apron etc. Billboards (7) which are substantially flush with the ground surface are located in the airside preferably adjacent the runways (2, 3, 4). The billboards (7) are preferably between the runway extremities and a take off/touch down zone (5). Alternatively the billboards are adjacent taxiways or taxiing areas. The billboards can be provided with movable images and/or interior lighting. A typical billboard size is 50 meters×50 meters (0.25 hectares).
Abstract:
A hydroformed drum brake shoe assembly for a vehicle and method of making same includes a hydroformed drum brake shoe. The hydroformed drum brake shoe assembly also includes a friction lining secured to the hydroformed drum brake shoe. The hydroformed drum brake shoe is a monolithic structure being integral, unitary, and one-piece.
Abstract:
The present invention provides a method for combining a fluid delivery system with an analysis system for performing immunological or other chemical of biological assays. The method comprises a miniature plastic fluidic cartridge containing a reaction chamber with a plurality of immobilized species, a capillary channel, and a pump structure along with an external linear actuator corresponding to the pump structure to provide force for the fluid delivery. The plastic fluidic cartridge can be configured in a variety of ways to affect the performance and complexity of the assay performed.
Abstract:
A capillary electrophoresis device as well as a process for fabrication of the device is disclosed. The capillary electrophoresis device comprises a device body structure having a plurality of reservoirs arrayed thereon for loading a sample, and a plurality of rows of grooves transversely defined to be connected with the reservoirs for receiving at least a capillary electrophoresis chip. The capillary electrophoresis chip comprises a straight main separation channel, an injection channel, and a plurality of sample transport channels defined thereon in liquid communication with the reservoirs. After an electrode means is applied, the sample can be transported into the separation channel for detection and analysis.
Abstract:
A female die of a closed die set and a punch for near net warm forging complex shaped parts such as lugs from axi-symmetrical workpieces are disclosed. The punch includes a bottom forming surface having opposed chamfer surfaces which move workpiece material laterally in the cavity, prior to and during warm forging, such that the die cavity is substantially evenly filled. Consequently, the resulting parts are evenly filled without requiring that the workpieces fit snugly in the die cavity.
Abstract:
An optical light engine includes a pair of lenticular microlenslet arrays (MLAs) located on each side of a polarization converter. Non-polarized light from a source in the engine is focused by the first MLA onto cells of the polarization converter which converts the light to a common state of polarization to increase efficiency and improve contrast in the system. A half wave retarder is included on the polarization converter to change the polarization of any light that is reflected from downstream optical components to match that of the forward propagating light. The second MLA, which includes a relatively large number of microlenslet elements, collects the light from the polarization converter and homogenizes the light to be highly uniform when received at a downstream imaging panel in the light engine such as a liquid crystal on silicon (LCOS) panel.
Abstract:
Physical models of wells are used to determine rate and phase composition for fluid produced from or injected into the wells on a near real time and continuous basis. The method can be used to alert operators or others of conditions in a well or field to permit more immediate response. The method can be more tolerant of sensor faults, sensor drift, anomalous data or other occurrences which could otherwise lead to incorrect output. More than one model can be used to permit a hierarchy of calculation such that the rate and phase determination is more tolerant of anomalous data. The calculated rate and phase values from one or more wells can be reconciled against facility data.
