Abstract: An electronic device includes an enclosure, a display positioned with the enclosure and defining a front face of the electronic device, and a haptic actuator positioned within the enclosure. The haptic actuator includes a housing comprising a wall and a movable mass positioned within the housing and configured to move within the housing to cause the haptic actuator to produce a vibrational response. The vibrational response includes a first component within a frequency range and a second component outside of the frequency range and providing a haptic output portion of the vibrational response. The haptic actuator also includes a tuning feature incorporated with the wall and configured to reduce the first component of the vibrational response while substantially maintaining the haptic output portion of the vibrational response.

Abstract: A wire winding machine (100) is disclosed which includes holders (106, 108) for holding a workpiece having a body (104a) with a hole (104b). A wire manipulator includes wire holders (116a, 116b, 116c) which are adapted for moving a piece of wire through the hole of the workpiece to form turns of winding of the piece of wire on the body of the workpiece.

Abstract: A metal forming head (113) is disclosed which includes a die (124) with a stamping portion (130), and a die holder (126) with a hole (136) therethrough. At least part of the stamping portion (130) of the die (124) is receivable through the hole (136) of the die holder (126). A bottom surface (144) of the die holder (126) which faces away from the die (124) is being adapted to abut a major surface (38a) of a sheet of metal (36). The die (124) is movable relative to an abutment part (138) of the die holder (126) to form the sheet of metal (36).

Abstract: A holder (13, 13a, 13b, 13c, 13d) for holding a sheet of metal (36) is disclosed which includes a base (40) for engaging with part of a first major surface (38b) of the sheet of metal (36) and a cover (50) for engaging with part of a second major surface (38a) of the sheet of metal (36). The base (40) and the cover (50) are engageable with each other to hold the sheet of metal (36) therebetween.
