Abstract:
A mobile station including a cover assembly and a wireless telecommunications signal receiving and generating assembly. Included in the cover assembly is a belt that substantially extends around the signal receiving and generating assembly, and a connector to hold the belt closed about the signal receiving and generating assembly. The belt includes a pair of side edges which define side openings through which the signal receiving assembly can be accessed. Advantageously, the belt is easily exchanged with other belts so as to vary the appearance of the mobile station. Further, the side edges are easily gripped by a user holding the mobile station. In another aspect, the belt includes an integrated key pad which overlies a plurality of key contacts of the signal receiving and generating assembly.
Abstract:
Method and Apparatus for fabricating a spacer frame for use in an insulating glass unit. A spacer frame separates spaced apart window panes in an insulating glass unit for use in fabricating a window. The spacer includes an elongated frame that is bent into a multi-sided closed form having outwardly facing surfaces for supporting the spaced window panes. An intermediate or bridging body portion of the frame transmits heat between the spaced window panes. Thermal interruptions in this intermediate body portion disrupt heat flow to raise the inside window temperature in winter and lower it in summer. This is referred to as the warm edge value. A thermal insulating film material preferably covers at least a portion of the intermediate body portion and covers the thermal interruptions.
Abstract:
A device for allowing rapid towing of a disabled military vehicle without requiring manual connection of a tow bar is disclosed. A “snatch block” molded from a high-strength plastic material is attached to the front bumper of a humvee or other similar military vehicle. The snatch block is equipped with teeth that are adapted to catch on the rear bumper of another vehicle. When the vehicle becomes disabled, another vehicle may tow the disabled vehicle by backing into the bumper of the disabled vehicle, where the snatch block is installed. This causes the snatch block to engage the rear bumper of the working vehicle such that the working vehicle may pull the disabled vehicle to a safe location. In an alternative embodiment, an upward-turned hook-shaped apparatus is mounted to the rear bumper of the rescuing vehicle. The apparatus is allowed some range of vertical mobility to allow the apparatus to slide under and catch the bumper of a disabled vehicle when the rescuing vehicle backs up in the direction of the disabled vehicle. The rescuing vehicle can then simply pull forward with the disabled vehicle being in tow.
Abstract:
The present invention provides a lightweight structure for simultaneously providing a reduced infrared and radar signature, while adding little or no weight to a vehicle. As such, the present invention allows for substantial improvements over prior systems. An example of the type of vehicle able to make use of the present invention is a military helicopter, but there is nothing within the spirit and scope of the present invention limiting it to any particular vehicle. The teachings of the present invention are useful with any vehicle for which a reduction in infrared emissions and microwave reflections is desired.
Abstract:
A method (138, 140, 142) for monitoring brake torque of an elevator (100) having a motor (116) is provided. The method (138, 140, 142) may engage an elevator brake (126) for a predefined duration, determine a displacement of an output shaft of the motor (116) during the predefined duration, and generate an alert if the displacement exceeds a predefined threshold.
Abstract:
A viscoelastic ink for direct writing of hydrogel structures includes a long chain polymer and a photopolymerizable moiety, which may be a photopolymerizable monomer or a photopolymerizable group attached to the long chain polymer. The ink may also include a crosslinking agent, a photoinitiator, and water. The long chain polymer is present at a concentration greater than a critical overlap concentration c* of the long chain polymer in the ink.
Abstract:
A mobile station (10) including a cover assembly (13) and a wireless telecommunications signal receiving and generating assembly (12). Included in the cover assembly (13) is a belt that substantially extends around the signal receiving and generating assembly (12), and a connector to hold the belt closed about the signal receiving and generating assembly (12). The belt includes a pair of side edges (30) which define side openings through which the signal receiving and generating assembly (12) can be accessed. advantageously, the belt is easily exchanged with other belts so as to vary the appearance of the mobile station (10). Further, the side edges (30) are easily gripped by a user holding the mobile station (10). In another aspect, the belt includes an integrated keypad which overlies a plurality of key contacts of the signal receiving and generating assembly (12).
Abstract:
Flow chambers are provided. In some embodiments, the flow chambers include an inner panel having at least one flow channel having an inlet/outlet opening on each end thereof formed therein, wherein the inlet/outlet openings are adapted to releasably receive a septum; one or more ports adapted to releasably receive a plug and for at least liquid communication with the at least one flow channel, and an outer frame that defines an outer portion of the at least one flow channel and that defines a perimeter of the flow chamber. In some embodiments, the flow chamber has overall dimensions of a standard multiwell plate and the at least one flow channel is located in a position that corresponds to a column location of the standard multiwell plate. Also provided are methods for producing the presently disclosed flow chambers and employing the same to assay biological features of cultured cells and/or tissues.
Abstract:
A soft robotic device includes a flexible body having a width, a length and a thickness, wherein the thickness is at least 1 mm, the flexible body having at least one channel disposed within the flexible body, the channel defined by upper, lower and side walls, wherein at least one wall is strain limiting; and a pressurizing inlet in fluid communication with the at least one channel, the at least one channel positioned and arranged such that the wall opposite the strain limiting wall preferentially expands when the soft robotic device is pressurized through the inlet.
Abstract:
Manipulation of flames is described using electric fields. In those instances in which electric fields are used, the electric fields may be time-varying gradient electric fields, and in some instances may be oscillating electiic fields. The manipulation may include extinction, suppression, control of mixing of the flame, concentration, and/or bending, among other types.
