A handheld tool includes a handle; an implement mount configured to detachably accept and to rigidly hold a user-assistive implement; an actuator assembly mounted to the handle to physically manipulate the implement mount relative to the handle; a first sensor disposed to sense an orientation of the handle; a second sensor disposed to sense an orientation of the user-assistive implement; a controller disposed in or on the handle and coupled to the actuator assembly and the first and second sensors; and memory coupled to the controller. The memory stores instructions for identifying a type of the user-assistive implement attached to the implement mount, selecting a behavior routine based upon the type of the user-assistive implement identified, and manipulating the user-assistive implement relative to the handle according to the behavior routine to aid performance of a task with the handheld tool.

A lifting device is hung in a manner relatively displaceable in the front-and-rear direction within a predetermined range with respect to the travel base that can be self-propelled in the front-and-rear direction, and a control device is provided with respect to the travel base. The control device causes the travel base to be self-propelled forward when the gait trainee moves forward and thus the lifting device is relatively displaced forward with respect to the travel base within the predetermined range, and causes self-propelling of the travel base to stop when the travel base is self-propelled forward faster than the gait trainee moves and then the lifting device is relatively displaced rearward with respect to the travel base within the predetermined range, thereby causing the travel base to be self-propelled forward in accordance with a pace of the gait trainee.

A rotary masturbation apparatus includes a cup holder, a cup body and a conductive structure arranged between the cup holder and the cup body. The cup body is rotatably connected to the cup holder, and defines an inner chamber therein for accommodating the male genitalia. The conductive structure includes a first conductive element and a second conductive element which are in contact with each other and are electrically conducted with each other. The first conductive element is fixed relative to the cup holder, and the second conductive element is fixed relative to the cup body. One of the first and second conductive elements is configured as a conductive ring, and the conductive ring is coaxial with the cup body.

The invention provides a sensing control method and apparatus, and a vibration massage apparatus. The method comprises: arranging a sensor which senses a trajectory of an external object, and controlling the change of output based on the direction of the trajectory. With the invention, a desirable control effect can be obtained based on the sensed direction of the trajectory of the external object without accurate positioning of the sensor. Not only the convenience of the sensing operation can be improved significantly, but also the control accuracy can be improved; meanwhile, the invention can be well applied to any device for control using several input control signals or variable input control signals for control, thus having a wide range of application and significantly optimizing user experience.

A back-following support device, a control method for preventing sedentariness, and a chair are provided. The back-following support device including: a backrest plate; a flexible back and waist support, including a cushion airbag disposed over the backrest plate; and a control system, including a controller, an air supply device for inflating the cushion airbag, a pressure-regulating valve for controlling the amount of air in the cushion airbag, and an air pressure sensor for detecting air pressure inside the cushion airbag; the air supply device, the pressure-regulating valve, and the air pressure sensor are all connected to the controller. The seat and the back-following support device can be adjusted to make the chair more comfortable, thereby effectively supporting the user's waist and/or back and meeting requirements of different people.

A massage chair includes a seat portion, a back portion a leg portion, and a massage carriage configured to move within the seat portion, the back portion, and the leg portion. The massage carriage includes comprises a percussive massage assembly comprising a motor, a reciprocating shaft coupled to the motor and configured to reciprocate in response to activation of the motor, and a reciprocating massage head coupled to the reciprocating shaft. The massage chair also includes a support mechanism associated with the percussive massage assembly. The support mechanism is configured to support a weight of a user of the massage chair, thereby allowing the reciprocating shaft and the reciprocating massage head of the percussive massage assembly to reciprocate.

A guide device providing a dimensional and ornamental guide that, engaging a leg of an ambulatory assist device used by a person, provides walking assistance, comprising a boot leg or sleeve for joining about a portion of the leg of the ambulatory assist device and receiving a resilient body axially for dimensional extents and receiving a guide member having a bottom glide surface for contact with a floor surface. A method of facilitating guidance of an ambulatory assist device is disclosed.
