摘要:
The invention relates to a pressure transducer with a capillary tube filled with a fluid for high pressure measurements. This pressure transducer comprises a sensitive element formed with a bore defining a cylindrical sensitive chamber, and respective capillary tubes attached to either ends of the sensitive element in fluid communication with the sensitive chamber. Advantageously, each capillary tube has a respective end outside threaded to engage in a mating thread-way provided in the sensitive element; moreover, a perimeter weld is provided for safety around each capillary tube near the connection to the sensitive element.

A security system architecture and method of operation that combines a local security network with control panel and sensors, a central monitoring station (CMS), and a separate operator computer server that provides a web portal for both the homeowner and CMS, that maintains a persistent connection between the control panel and CMS allowing failsafe dual-path signaling. This dual-path signaling technique is extended to provide an effective “smash and grab alarm”, and various approaches to dual-path signal management are disclosed including handshaking, persistent domain monitoring, relayed Operator 3-to-CMS signaling, etc. Improved processes for remotely accessing video are also disclosed along with an improved process for remote control panel configuration, and control panel interfacing with home automation appliances.

An ear-fitting headphone restraint system includes an attachment assembly configured to be coupled to a portion of a stem of an ear-fitting headphone. The ear-fitting headphone is configured to be positioned against an ear canal of an ear. The system also includes a brace assembly coupled to the attachment assembly and configured to restrain the ear-fitting headphone against the ear canal by creating compression forces. The compression forces include a first compression force between the ear-fitting headphone and the ear canal. The compression forces further include a second compression force between a concha of the ear and the brace assembly. A first side of the brace assembly is configured to be positioned on a portion of the concha, and the attachment assembly is operable to transmit the first compression force and the second compression force between the brace assembly and the ear-fitting headphone.

A linear stacked stage suitable for REBL may include a first upper fast stage configured to translate a first plurality of wafers in a first direction along a first axis, the first upper fast stage configured to secure a first plurality of wafers; a second upper fast stage configured to translate a second plurality of wafers in a second direction along the first axis, the second upper fast stage configured to secure the second plurality of wafers, the second direction opposite to the first direction, wherein the translation of the first upper fast stage and the translation of the second upper fast stage are configured to substantially eliminate inertial reaction forces generated by motion of the first upper fast stage and the second upper fast stage; and a carrier stage configured to translate the first and second upper fast stages along a second axis.
摘要:
A computing device receives acceleration information from an accelerometer mechanically coupled to a wireless controller, magnetic bearing information from a magnetometer mechanically coupled to the wireless controller, and rotation information from a gyroscope mechanically coupled to the wireless controller. When the wireless controller is primarily vertical, the computing device determines a rotation angle of the wireless controller by filtering the rotation information using the acceleration information. When the wireless controller is primarily horizontal, the computing device determines the rotation angle of the wireless controller by filtering the rotation information using the magnetic bearing information.

An impeller includes a top shroud, a bottom shroud, and a plurality of vanes extending from the top shroud to the bottom shroud. The top and bottom shrouds are generally planar, and a lower edge of each vane tapers from an outer edge of the bottom shroud to a transverse tip edge thereof.

A method for displaying images on a curved display surface is described herein. The method includes receiving a graphical object and distorting the graphical object at run-time such that an appearance of the graphical object on the curved display surface will be substantially similar regardless of a position of the graphical object on the curved display surface when viewed at a viewing axis that is approximately orthogonal to a plane that is tangential to the curved display surface at a center of the graphical object. The method may further include displaying the graphical object on the curved display surface.
