Abstract: A method of connecting stranded wire to a lead-frame body 10 includes the provision of a stranded wire 12. It is ensured that insulation is stripped from an end 14 of the stranded wire. An electrically conductive lead-frame connection structure 16 is associated with the lead-frame body. The end 14 of the stranded wire is inserted into the lead-frame connection structure 16 so that the lead-frame connection structure substantially surrounds the wire end. Solder flux is injected so as to be substantially about a portion of the end of the stranded wire. The lead-frame connection structure is placed in contact with a bottom resistance welding electrode 18 or a top resistance welding electrode 20. The electrode that is not presently in contact with the lead-frame connection structure is moved so as to contact the lead-frame connection structure to resistance weld the wire end 14 to the lead-frame connection structure 16 and thereby define a solder crimp connection 22 of the wire end and the lead-frame connection structure.

Abstract: A method of starting a brushless DC motor 12 at any initial speed (A) establishes a initial stator-field speed and setting a counter of synchronization, (B) measures a speed of a rotor of the motor, (C) compares the speed of the rotor with the stator-field speed to determine if the rotor is synchronized with the stator-field. If the rotor is not synchronized with the stator-field, the method includes (a) re-setting the counter of synchronization, (b) increasing an acceleration portion of motor current (Iacc) to enhance torque, (c) setting the stator-field speed higher than the rotor speed, (d) calculating a period of an open-loop timer, (e) calculating a value for a load portion of the motor current (Ild), where total motor current I=Iacc+Ild, (f) performing commutation based on the open-loop timer and returning to step (B) until the rotor is synchronized with the stator-field. If synchronization of the rotor and stator-field is determined, the method includes incrementing the counter of synchronization, determining if the counter is greater than a certain value, and if the counter is greater than the certain value, switching from open-loop commutation to closed-loop commutation. If the counter is not greater than the certain value, the method includes proceeding to step (c).

Abstract: There is disclosed an orthotic device adapted for use with a hand of a user to restore grasping function. The device includes a finger retaining member and thumb support. The finger retaining member is pivotally moveable from a first open or non-grasping position when the finger retaining member is spaced from the thumb support, to a second position where the two are adjacent. The device achieves this function by incorporating a suitable shape memory alloy suitably associated with the finger retaining member and thumb support.

Abstract: A method provides, on a printed circuit board 16, at least a first and a second printed circuit board fuse trace A, B placed in parallel with each other in a main current carrying path 18. In a normal operating condition, it is ensured that 1) all of the traces carry a portion of a load current and 2) the traces are configured to prevent opening of the traces in the normal operating condition. When a fault condition occurs, it is ensured that the first trace A opens before a resistance thereof increases so as to divert more of a load current to the second trace B, thereby causing the second trace B to open after opening of the first trace A.
