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: A device for locating bowling ball gripping apertures with respect to a bowling ball weight block angle inherent to that particular bowling ball and the track of a particular bowler. One embodiment of the device includes a curved base portion adapted to substantially rest on a curved surface of a bowling ball, the perimeter of the base portion including degree indicators and the center of the base portion including a hole, at least four curved angle indicator arms adapted to substantially rest on a curved surface of the bowling ball, the angle indicator arms including length measurement indicators, the angle indicator arms connected with and extending from the curved base portion, and at least two of the angle indicator arms are adapted to rotate about the center of the curved base portion.

Abstract: A grip-enhancing material for preventing two objects in contact with each other from slipping is disclosed herein. The grip-enhancing material of the present invention includes a plurality of recesses, such as suction cups, positioned on a base material. The suction cups may be connected to the base material by a stem or may be connected directly to the base material. The base material can be affixed to a first object with adhesive and the grip-enhancing material engages a second object upon contact through suction and/or friction forces. In one application, the grip-enhancing material may be applied to prevent heavy objects placed on smooth surfaces from slipping. In another application, the grip-enhancing material is used to enhance the frictional characteristics of gripping surfaces on certain objects. Further, the grip-enhancing material may be affixed directly to various body parts to enhance a person's ability to grip various objects.

Abstract: The control-enhancing material of the present invention includes a plurality of recesses, such as suction cups, positioned on the palm portion of the bowling glove. The areas covered by the control-enhancing material include the underside of the index finger, the underside of the thumb, the underside of the little finger, and the underside of the middle and ring fingers. Basically, the control-enhancing material 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 works to grip the surface of the bowling ball 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.

Abstract: A bowling aid adapted to be mounted on either the bowler's index or little finger. The aid is a sheath into which the bowler's finger is inserted. Appropriate padding is provided in the sheath for gripping and protecting the finger. The padding can include a full-finger insert having removable serrated longitudinal sections. On the outer end of the sheath there is provided a plate which extends outwardly from the sheath under the head metacarpal joint of the bowler's index finger and part of the palm of the bowler's hand and is provided with a concave surface with a frictional coating thereon for assisting the bowler in gripping the bowling ball. The concave surface and friction coating extend along the length and width of the sheath. The bowler presses the plate and the length and width of the sheath against the surface of the ball to generate enhanced control during ball release. The sheath can define a gap along its length with a fastening system attached to the sheath to accommodate varying finger sizes.

Abstract: A train communication and control system is described having the cars of the train connected by a two-wire train line running continuously from car to car. Each car has a transmitting circuit and a receiving circuit connected across the line. Any car may be selected to be a master unit. The selection of one car as a master unit disconnects the power sources of all other cars from the train line, leaving the master unit power source as the sole power source for the line. The master unit or any other car unit communicates with each other car by causing a high voltage ("mark" state or logic one) or a low voltage ("space" state or logic zero) to be on the train line. Each non-master car can receive a communication from a transmitting circuit, or can transmit to another car by applying a low impedance across the train line to change from a "mark" state to a "space" state. The power source consists of a voltage regulator with precision constant current limit.
