Abstract: A progressive resistance knee pad coupled to the inner surfaces of a knee brace to prevent metal components of an orthotic support from contacting clothing, tissue or skin surface of the wearer of the orthotic support appliance. The knee pad has a cushion layer having a contoured contact surface and a support surface. A middle layer has a mating surface and a middle layer base surface. A base layer has a top surface and a mounting surface. An imbedded mounting plate has uniform thickness and is imbedded in the base layer. The middle layer support surface is formed to shape the cushion layer contact surface to conform with a contoured surface. The thickness of the middle layer is controlled and adjusted to provide a substantially planar middle layer base surface. The base layer imbedded mounting plate is characterized to receive fastening means for coupling the progressive resistance knee pad to the appliance.
Abstract: Two methods for determining a best initial heading estimate for use in an AINS system, while recording position data values and in-motion data values, assigning incremental changes to indexed heading ?k, calculating a set of time indexed present AINS position values and a corresponding set of time indexed absolute horizontal position measurement residual values, recording the absolute maximum time indexed horizontal position measurement residual and the corresponding value of ?k returning to the step of assigning an incremental increase to a next value to indexed heading ?k up to 360 degrees, identifying the maximum time indexed horizontal position measurement residual and corresponding ?k, followed by identifying the ?k having the smallest absolute maximum horizontal position measurement residual as Ak Second method uses a circular array of AINS ENGINES each with a different ?k running in parallel and finding smallest horizontal position measurement residual for Ak.

Abstract: A Sensor glove is an instrument, in the same way that a piano is an instrument. The Sensor glove is purchased and the owner then learns to use it and the sensors therein to develop the performance of a sound, character or model, or to “conduct” or “play” the sensor movements and experience the response of the model in real time. Several performers with a number of the Sensor glove can control over 200 motors or hundreds of control points on a character at one time, manipulate audio data, or computer images etc. The characteristics of the sensors on the gloves can be adjusted to the needs and demands of the wearer or the many performer and wearers in those venues where multiple performers are used with many gloves to control or produce the motions and sounds of many distinct characters in a screen play.

Abstract: A method of fiber production relating in general to electrospinning and specifically to MEMS (Micro ElectroMechanical Structures). Utilizing integrated circuit manufacturing processes, a nanoscale, self-contained device has been developed to execute the process of electrospinning large arrays of fibers and fiber arrays. One of the benefits of using the disclosed MEMS device is that the voltage required to produce a “so called” Taylor Cone would is substantially reduced and the requirement of a hydrostatic feed negated through the use of passive capillarity based wick surface treatment.

The lens group, the middle lens and the final lens elements are coaxially aligned and on an optical axis normal to the image plane.
Abstract: A Land Surveyor System with Reprocessing is carried by a surveyor moving from a first known position at the start of a survey interval to a second known position at the end of the survey interval has an AINS (aided inertial navigation system) that provides a continuing sequence of time-indexed present position values. A Position Computing System uses a program that stores the sequence of time-indexed present position values in a memory. A reprocessing computer and program is activated at the second known position to access and process the continuing sequence of time-indexed present position values with a smoothing program to provide indexed and adjusted present position values for at least some of the time-indexed present position values. The system is packaged for transport and use by a surveyor. A switch permits the surveyor to signal that the unit is stationary as a reset for the AINS.

Abstract: A manually releasable clip holder for receiving, securely holding and manually releasing a serpentine clip has a substantially flat base-plate. An insert is coupled to the base-plate. The insert has an insert cover with a top edge that forms an insert channel over the base plate. A channel aperture is formed at the insert cover top edge. A flap is pivotally coupled to the base plate and has a bottom edge. A spring is coupled to provide a restoring force to return the flap to a predetermined restored position with the flap bottom edge positioned above and beyond the insert cover top edge and the channel aperture. The separation between the flap bottom edge in the restored position and the insert cover top edge forms a window to the channel aperture. The flap is displaced toward the base-plate in response to a light deflection force from a serpentine clip.
Abstract: A walking stick navigator (WSN) apparatus and process comprises an aided INS (AINS) on a staff assembly similar in operation and appearance to a GPS survey instrument. However, when GPS is available, the AINS is aided by GPS data, and the surveyor manipulates the staff assembly like a standard GPS survey instrument. When GPS is not available due to signal obstruction, the surveyor manipulates the staff assembly as a walking stick. A switch means coupled to the lower end of the staff assembly provides a stationary interval signal when the surveyor plants and holds the WSN on the ground while walking. An input process is coupled to the AINS output signals and to the stationary interval signals and provides at least one aiding input signal to the AINS for each successive stationary interval, thereby allowing the AINS to control its velocity error and position drift during a GPS outage.
