Abstract

Improved techniques for avoiding and remediating connector-related stripping and other material damage are provided. In some aspects, specialized drive heads and systems are provided in conjunction with sensors for detecting proper distance characteristics and contact orientations (a.k.a., “seating”) with connectors, which, upon sensing improper seating, reduce, reverse-pulse or otherwise alter or remove power. The specialized driver heads may include reverse-grip members that pull the driver-head into the seated position. In other aspects, multiple-section connector sets are included, which may be self-tightening, and create detectable conditions of potential tightening energy being expended and/or loosening occurring, allowing an external sensor to sense such a condition and identify a connector that has loosened, slipped, or may be in need of recharging or tightening. A specialized connector head may selectively break away before stripping and thereby expose a stronger, secondary driver head. Associated driver refinements are also provided, which may further avoid damage.

Claims

1. A connector driving system comprising:

a motor;

a driver bit with a plurality of isolated electrical and/or magnetic contacts; and

a control system configured to control driving torque and speed and/or connector tightness in accordance with sensing proper seating of said driver bit with a connector head and configured to execute the following operations;

sense whether isolated electrical and/or magnetic contacts within the driving system become bridged and engage in communication with one another;

determine whether said communication bears at least one attribute associated with proper seating of the driving system with a connector head;

create driving torque, speed and connector tightness based on said communication; and

wherein said communication attribute is individually set, with respect to a particular connector head and driver bit interaction.

2. The connector driving system of claim 1, wherein the system is programmed with readings associated with proper seating of the driver bit into at least one connector head.

3. The connector driving system of claim 1, wherein the system senses proper seating by whether a circuit is completed by more than one isolated electrical contact in the driver bit, and a connector head engaged with said driver bit is used as an electrical bridge.

4. The connector driving system of claim 1, wherein said isolated electrical and/or magnetic contacts reside on at least one outer surface of said driver bit.

5. The connector driving system of claim 4, wherein said isolated electrical and/or magnetic contacts are separated from one another by an insulating layer.

6. The connector driving system of claim 5, wherein said isolated electrical and/or magnetic contacts are configured to become bridged by said proper seating of said driver bit.

7. The connector driving system of claim 6, wherein said driver bit comprises additional electrical and/or magnetic contacts within a grip section.

8. The connector driving system of claim 6, wherein at least one of said isolated electrical and/or magnetic contacts is joined to said additional electrical and/or magnetic contacts via at least one conductor.

9. The connector driving system of claim 4, wherein said driver bit is a Phillips head bit.

10. The connector driving system of claim 4, wherein said system determines a tightness of at least one connector and/or material engaged by said system.

11. A connector driving system comprising:

a motor;

a driver bit with a plurality of isolated electrical and/or magnetic contacts; and

a control system configured to control driving torque and speed and/or connector tightness based on sensing proper seating of said driver bit with a connector head and configured to execute the following operations;

sense whether some of said isolated electrical and/or magnetic contacts within the driving system become bridged and engage in communication with one another;

determine whether said communication indicates a proper seating of the driving system with a connector head;

create driving torque, speed and connector tightness based on said determination;

wherein said contacts are engaged by at least one movable probe that is a part of the driver system; and

wherein said communication is individually set, with respect to a particular connector head and driver bit interaction.

12. The connector driving system of claim 11, wherein the movable probe is a single projection, biased toward penetrating a cavity in any connector head engaged with and complementary to said driver bit, and wherein said projection will provide a substantially fixed distance when said driver bit is properly seated into a connector head complementary to said driver bit, and will not provide that same substantially fixed distance in the majority of other possible, improper driver bit orientations in engagement with a connector head.

13. The connector driving system of claim 12, wherein the system is configured to be programmed with a distance reading, or range of distance readings, of the driver bit from a connector head engaged with said driver bit;

wherein the programmed distance reading, or range of distance readings, is associated with proper seating of the driver bit with said connector head engaged with said driver bit.

14. The connector driving system of claim 13, wherein the system compares real-time distance readings of the driver bit from a connector head, and compares them to said programmed distance reading or range of distance readings.

15. The connector driving system of claim 14, wherein the system ceases or reduces delivery of driving power and/or reverse pulses driving power, in response to a real-time distance reading that substantially exceeds said programmed distance reading or range of distance readings.

16. A connector driving system comprising a physical contact sensor and a control system, wherein said control system performs operations to:

control driving power based on sensing change in seating of a driver bit against other objects; and

prevent slippage and damage to or by the system by applying remedial power actions, including, but not limited to, a reverse-pulse of power;

wherein said remedial power actions are executed if said change in seating is sensed.

17. The connector driving system of claim 16, wherein:

the remedial power actions comprise reducing and reverse-pulsing power when a substantial decrease in required power to turn the drive head is sensed while the system is operating in a connector-tightening direction.

18. The connector driving system of claim 16, wherein the remedial power actions comprise reducing and reverse-pulsing power when a substantial increase in driver bit speed is sensed while the system is operating in a connector-tightening direction.

19. The connector driving system of claim 16, wherein said sensed change in seating is determined by comparing (A) a sensed distance between a part of a driver bit and a part of a connector engaged with said driver bit, with (B) a recorded distance associated with proper seating of a selected and used driver bit type and connector head type.
