A tunable static balancer arrangement on a mechanic device, for adjustably compensating a positive force needed to actuate a moveable part of the device from a first position to a second position. The arrangement comprises a moveable actuation member for transferring movement from an input to said moveable part, the actuation member being moveable in a general axial direction, at least one first stiffness element that exerts in at least one position a negative force in the axial direction counteracting at least partially said positive force when the moveable part is moved from the first position to the second position, at least one adjustable second stiffness element, wherein said first stiffness element is connected on one end to said moveable actuation member, and on the opposite end to the adjustable second stiffness element, such that the first stiffness element exerts a positive force on the adjustable second stiffness element, and such that when stiffness of said adjustable second stiffness element is adjusted, the negative force of said first stiffness element in the axial direction is altered. Also provided is a compliant grasper comprising the tunable static balancer arrangement.

An engine mount device includes a housing, a carrier within a cavity in the housing, and a flexure flexibly connecting the carrier to the housing, with a pin disposed in a hole in the carrier to support an engine. A method of providing isolation in the engine mount device includes transmitting a force from the pin into the carrier; mechanically isolating the carrier from the housing via the flexure; and providing, via the flexure, a higher stiffness in one or more radial directions of the hole compared to a stiffness provided in an axial direction of the hole.

A drivetrain assembly (100) for a personal care device (10), the drivetrain assembly including a primary resonator (110); a secondary resonator (140) configured to reduce vibrations transmitted from the motor to a body (12) of the personal care device; a fixed point (130) positioned between the primary resonator and the secondary resonator; a first spring member (120) connected at a first end to the primary resonator and at a second end to the fixed point; a second spring member (150) connected at a first end to the secondary resonator and at a second end to the fixed point; a coupling spring (160) connected at a first end to the primary resonator and at a second end to the secondary resonator; and an actuator (170) configured to exert force on at least one of the primary resonator and the secondary resonator.

A deformable body, wherein the body is constructed from a multiplicity of layers of a polymer construction material and in which a construction direction is defined perpendicular to the layers. The body preferably comprises layers with a multiplicity of curve pairs (10) which are formed by the construction material and which run in the same direction as one another, the curve pairs comprise in each case two periodic curves (20, 30) running oppositely with respect to one another, and the curve pairs comprise portions of maximum spacing to one another (40, 41, 60, 61) and portions of minimum spacing to one another (50, 51, 70, 71). In one part of the layers, in adjacent curve pairs (10), at least one portion of maximum spacing (41) of one curve is connected to a portion of maximum spacing (60) of an adjacent curve, in a further part of the layers, in adjacent curve pairs (10), at least one portion of maximum spacing (41) of one curve is not connected to a portion of maximum spacing (60) of an adjacent curve, in a further part of the layers, in adjacent curve pairs (10), at least a part of the portions of minimum spacing (50, 51) are connected to one another, and in a further part of the layers, in adjacent curve pairs (10), at least a part of the portions of minimum spacing (50, 51) are not connected to one another.
