Abstract:
Systems and methods for digitally controlling sensors, one embodiment being a digital controller for a capacitance diaphragm gauge which is embedded in a digital signal processor (DSP). The digital controller receives digitized input from a sensor AFE (30) via a variable gain module, a zero offset module and an analog-to-digital converter. The controller automatically calibrates the received input by adjusting the variable gain and zero offset modules.
Abstract:
A bowling aid (35) adapted to be mounted on either the bowler's index or little finger. The bowling aid (35) is a sheath (36) into which the bowler's finger is inserted. Appropriate padding (42) is provided in the sheath for gripping and protecting the finger. On the outer end of the sheath (36) there is provided a plate (48) which extends outwardly from the sheath (36) and is provided with a concave surface with a frictional coating (50) thereon for assisting the bowler in gripping the bowling ball. The concave surface and friction coating (50) extend along the length and width of the sheath. The bowler presses the plate (48) and the length and width of the sheath (36) against the surface of the ball during bowling to generate enhanced control.
Abstract:
Systems and methods for digitally controlling sensors. In one embodiment, a digital controller for a capacitance diaphragm gauge is embedded in a digital signal processor (DSP). The controller receives digitized input from a sensor AFE via a variable gain module, a zero offset module and an analog-to-digital converter. The controller automatically calibrates the received input by adjusting the variable gain and zero offset modules. The controller also monitors and adjusts a heater assembly to maintain an appropriate temperature at the sensor. The controller utilizes a kernel module that allocates processing resources to the various tasks of a gauge controller module. The kernel module repetitively executes iterations of a loop, wherein in each iteration, all of a set of high priority tasks are performed and one of a set of lower priority tasks are performed. The controller module thereby provides sensor measurement output at precisely periodic intervals, while performing ancillary functions as well.
Abstract:
The control enhancing material (38) of the present invention includes a plurality of recesses (40), such as suction cups (44), positioned on the palm portion (26) of the bowling glove (20). The areas covered by the control-enhancing material include the underside of the index finger (28), the underside of the thumb (36), the underside of the little finger (30), and the underside of the middle and ring fingers (32, 34). Basically, the control-enhancing material (38) is positioned at all or some of the areas on the glove that contact the bowling ball when the glove is worn on the hand of the user and the user is holding a bowling ball. The control-enhancing material (38) works to grip the surface of the bowling ball (23) by a suction force and a friction force. The additional grip is maintained even though the user moves his or her hand slightly either away from, towards, or laterally with respect to the bowling ball (23).
