Abstract: The invention relates to a novel 4-phase motor and generator device with increased efficiency for generating electrical energy. The device features a stator wall with eight stator slots and four pole groups, and an armature rotatable within the stator wall. The eight stator slots are divided into four pole groups of opposing stator slots, the two opposing stator slots include a N stator slot and a S stator slot. N and S stator slots are alternatively activated in response to rotation of the armature. The activation of the pole groups results in a rotating magnetic field within the stator wall, and only six of the eight poles are actively coupled in any given configuration. The invention also includes a method of operating the motor for generating electrical energy with increased efficiency and an environmentally friendly manner compared to conventional motors.

Abstract: The majority of adult devices have been designed for an individual to hold. However, it would be beneficial to provide users with a range of adult devices that support their use either in a hands free manner and/or are compatible with being worn by the user for varying periods of time from intermittent/occasional short durations through to extended wearing such as all day for example. In order to provide such wearable devices being able to separate the drive means from the stimulation means provides increased design flexibility as well as allowing different designs of adult device to be implemented as the design flexibility within the appropriate regions of the user's anatomy increases when the large vibratory motors are removed and connected to the stimulation means via flexible drive shaft. Further, beneficially, flexible drive shafts allow operation as the user moves during normal activities, such as sitting, standing, walking, etc.

Abstract: A linear actuator system comprising a linear actuator having a housing and an outer tube, which with a rear end is secured to a side of the housing at a front end thereof. The outer tube surrounds an electric motor driven spindle unit and an activation element. The linear actuator system further comprises a control box having a control, where the control box is arranged in the angle between the housing and the outer tube on the linear actuator. The control box is fastened with a mounting bracket to the outer tube on the linear actuator. The mounting bracket comprises a tubular portion, whereby it can be pushed in over the outer tube and the mounting bracket and the control box are also designed with interacting fastening means for fastening the control box to the mounting bracket. The tubular portion of the mounting bracket has an axially extending slit and the interacting fastening means between the mounting bracket and the control box are constituted on both sides of the slit. The interacting fastening means are designed such that when the control box is fastened onto the mounting bracket, the slit contracts so that the tubular portion of the mounting bracket tightens around the outer tube on the linear actuator. The construction is characterized in that the control box is only fastened to the mounting bracket on the outer tube of the linear actuator. This simplifies the fastening quite considerably while simultaneously simplifying the design.

Abstract: A vibration motor includes an eccentric weight whose center of gravity is positioned outside a shaft and a holder made of resin and holding a ring-shaped back yoke and the eccentric weight. The back yoke includes an overhang portion which extends farther inward in a radial direction than an inner side edge of the opening of a rotor magnet. The holder includes a penetrated portion which is a tube-shaped portion positioned at an axially inner side of the rotor magnet and extends in the axial direction surrounding the shaft, an upper surface portion which expands radially outwardly from an upper side of the penetrated portion to cover an upper surface of the eccentric weight, and a lower surface portion which expands radially outwardly from the lower side of the penetrated portion to cover a lower surface of the overhang portion.
