Abstract: A cardiorespiratory fitness optimizer apparatus includes a mouthpiece and a valve assembly. The mouthpiece includes lower and upper tooth beds and an anterior manifold. The manifold terminates anteriorly at a centralized valve assembly interface and includes at least one air-letting aperture. The valve assembly is matable with the centralized valve assembly interface and includes an adjustable aperture. The user is able to adjust the aperture for increasing and decreasing airflow resistance therethrough for optimizing cardiorespiratory fitness. The cardiorespiratory fitness optimizer apparatus may include at least one sensor for sensing airflow activity within the valve assembly and communicating data relating to the airflow activity to an external device for displaying human readable output relating to the airflow activity upon the external device.

Abstract: An athletic mouthguard with lung exercising variable, two-way airflow-restricting valve is disclosed. The mouthguard has a mouthpiece with a lower tooth bed and an upper tooth bed overlying the lower. Outer and an inner sidewall connects the beds. A channel passes between the lower and upper beds with a first end open within the inner sidewall and a second end open within the outer sidewall. Certain embodiments include a channel wall which separates the channel into multiple channels. A manifold in fluid communication with the channel terminates to a centralized aperture with a valve seat. A rotatable valve member in the valve seat has an aperture therethrough.

Abstract: An automatic sheet printing and alignment system includes a holding table; a transport system for moving the table through a plurality of stations; a first station for positioning a sheet on the table; a second station for printing features on the sheet positioned on the table; a third station for receiving the printed sheet from its position on the table to compile a stack of sheets with their printed features in predetermined alignment; and a control system for sequentially moving the table through the stations for repeatedly printing and stacking each sheet aligned with prior printed and stacked sheets received, transported and printed by the same table.

Abstract: Method and apparatus for nondestructively removing a cut segment of predetermined shape from a limp material sheet workpiece and transporting the cut workpiece segment to a staging area for further processing. The cut segment is picked up by a picker which may comprise an array of carding strips, each strip having a plurality of needle-like elements, arranged such that each strip can be displaced relative to its adjacent strips and the needle-like elements of each strip are angularly offset with respect to the needle-like elements of the adjacent strips. Such removal and transporting having is accomplished without distorting the shape of the cut segment.

Abstract: A method and apparatus for the automated assembly of sleeves onto the body of the garment. In the present invention, the garment body is placed on a first fixture resembling a mannequin. The sleeves are placed inside facing out on a second conical fixture. Automatically, each sleeve is positioned and sewn onto the garment body and the finished garment is removed from the first fixture. Through the use of sensors, each sleeve is precisely and consistently sewn to the garment body. The result is a high quality garment produced at a lower cost.

Abstract: An automatic edge sewing system and method for sewing together the edge of a plurality of parts in which the parts to be sewn are clamped together in a sewing machine having a reciprocating needle; the parts are mounted for rotation about a first rotational axis through the pans and for linear translation along a linear axis between the first rotational axis and the axis of the needle. The pans are steered about a second rotational axis parallel to the needle axis for adjusting the angular position of the linear axis about the needle axis. The parts are fed through the needle axis and the position of the edge of the parts proximate the needle axis is sensed; the steering and the feeding of the parts through the needle axis is controlled in response to the sensing of the edge position while the pans passively float about the first rotational axis and along the linear axis to enable the parts to be sewn accurately, automatically proximate the edges.

Abstract: A differential mechanism such as a limited slip differential mechanism which is automatically engageable or disengageable in response to preselected conditions and through a clutch arrangement controls the relative rotative speeds of the vehicle wheels and related axle shafts. A single sensor is utilized to sense the angular velocity of a gear, such as a drive axle ring gear, and provides a first signal proportional to the velocity of the monitored gear. A control converts the first signal into a second signal proportional to angular acceleration of the monitored gear and will cause the actuator to engage the clutch when acceleration of the monitored gear, or related member, exceeds a predetermined maximum.

Abstract: A drive axle system of the type useable in a 6 .times. 6 vehicle, especially one utilizing a tandem axle assembly to transmit torque from the vehicle transmission to first and second rear drive axles. The system comprises torque dividing means within the tandem axle assembly and first and second torque transmitting means, such as the side gears of a differential. A first gear means transmits torque from the first differential side gear to the first rear drive axle and a second gear means transmits torque between the second differential side gear and the second rear drive axle. A third gear means is in engagement with the first gear means and may be clutched to a drive shaft to transmit torque directly from the tandem axle assembly to the front drive-steer axle, thus eliminating the need for a transfer case.
