Abstract: A computer readable media, a method, and a system registering a third party application providing an available communication system between a local user and a remote user identity, storing information related to the available communication system in a first database, obtaining contact information for the remote user identity from the third party application, determining a communication type for the third party application, pairing the remote user identity with a contact, and updating a graphical representation of contact information.

Abstract: An additive manufacturing apparatus includes an additive manufacturing print head and a nozzle that receives a bio-based shape memory polymer material and a bio-based material. The nozzle extrudes the bio-based shape memory polymer material and the bio-based material onto a substrate to form a bio-based shape memory polymer part or product.

Abstract: A network connection on a processor-based system may be managed by a software layer that accommodates for a variety of different types or characteristics of network connections. In effect, the software layer abstracts the characteristics of a variety of different connections and enables the client on the processor-based system to connect without concern for the particular characteristics of the resident connection. In addition, the software layer may determine when to release a connection to the Internet. This may reduce the disruption that may occur when multiple clients use the same connection and one of those clients disconnects the connection, thereby terminating the access to the connection by one or more other clients.

Abstract: A flow control device comprises an outer sleeve having at least one aperture through its wall, and an inner sleeve having at least one aperture through its wall. Relative sliding movement of the sleeves is provided between “open” positions allowing for variable flow of fluid through the apertures of the sleeves and “closed” positions. A pressure-reducing region is arranged to reduce the pressure of fluid flowing through at least one aperture of one of the sleeves.

Abstract: An apparatus and a non-destructive method for evaluating material strengths is described. One embodiment of the apparatus comprises a waveform generator that generates either (1) a sinusoidal waveform having a frequency that sweeps from a low frequency to a high frequency, or a high frequency to a low frequency, wherein the low frequency is from about 10 Hz to about 150 Hz, and the high frequency is from about 6,000 Hz to about 24,000 Hz, or (2) a pseudo random within the frequency range of from about 150 Hz to about 6,000 Hz. An electromechanical driver is electronically linked to the waveform generator and mechanically coupled to a test material, particularly in-service utility poles, at a drive position. Force and acceleration sensors are coupled to the test material at various positions. A microprocessor is used to collect digitized data from the force sensor and the accelerometers, perform a transfer function and determine the strength remaining in the test material using a neural network model.

Abstract: An array of radiation detectors is rotated about one or more sources of fan-shaped substantially planar radiation beams which are, in turn, rotated in the opposite direction about a three-dimensional body such that substantially parallel paths are defined between given individual detectors of the array and the radiation sources during the course of their oppositely directed movements. Radiation absorption measurements are taken along thusly defined plural intersecting sets of substantially parallel paths within a desired cross-section of the three-dimensional body to provide data for use in computing and displaying a constructed visual image of structures having different radiation absorption coefficients within the cross-section.

Abstract: The liquid chromatograph comprises a multiple piston pump (1) which is arranged so that the delivery strokes of two pistons overlap to such an extent that for all designed liquid delivery pressures and compressibilities no period exists when no piston is delivering liquid. Thus for all other than worst case conditions there are periods in each pump cycle when two pistons are delivering liquid. The start of these periods is detected by the pressure increase produced at the outlet of the pump and measured by a pressure transducer (5). The output of the pressure transducer is fed via path (14) to a motor drive circuit (10) which controls a motor (4) which drives the pump (1) via a shaft (3) so that the speed of advance of the pistons is halved until one of the pistons ceases delivery. Consequently a relatively pulse free liquid flow is produced by the pump with a relatively simple motor speed control system.

Abstract: Rigid supporting structures for the components of high precision optical instruments, such as interferometers or monochromators, have hitherto been based on massive castings. Such castings suffer from residual non-recoverable changes of shape during temperature cycling, due to the differential temperatures set up in the castings. The invention provides a rigid structure assembled from a number of flat sheet structural elements. Each sheet element is substantially rigid in its own plane and is attached to one or more other sheets at points of contact which are such that the edge of one sheet bears against the surface of another sheet with the planes of the two sheets being perpendicular in the region of the points of contact. An open ended rectangular box structure may be assembled from two sheets, each with a single right angled fold. Each point of contact and attachment may be formed as a foot standing proud from the remainder of the sheet edge.

Abstract: A sine bar mechanism comprises an arm of radius R pivoted about an axis which is also the axis of a diffraction grating. An elongated member is pivotally mounted at one end, and is pivotally connected to the arm at its other end. The coordinates of the point at the pivotal mounting at one end of the member and the length of the elongated member are chosen to optimize the characteristics of the mechanism. Embodiments in which the elongated member comprises a lead screw and the pivotal connection comprises a nut pivotally attached to the arm and engaging the lead screw are described and their use in various types of monochromators are portrayed.
