An implantable medical device for treating the back of a patient. Stimulation energy is delivered to muscles or joint capsules or ligaments or nerve fibers to improve the heath of the back.

A spinal support device for applying a directed and concentrated force on the sacrum to position the sacrum and pelvis to thereby establish a desired spinal posture when in a seated position. The device provides isolatable force on the sacrum from the sacral base line downwardly to a bottom seat surface and for a width across an individual's back approximately equal to twice the dimension of the posterior portion of the individual's sacrum.

A mobile communication system according to the present invention is provided with a base station and a mobile station that communicates with the base station. In a communication protocol between the base station and the mobile station, a plurality of state update frames are defined in a time domain. The base station is configured to transmit a state update data to instruct that the mobile station is set to either an active state or a suspended state, in each of the plurality of the state update frames. At the same time, the base station is configured to transmit a packet only to the mobile station that has been set to the active state by the state update data. The base station in advance notifies the mobile station of packet transmission by transmitting a control data including a data necessary to receive the packet, earlier than the packet transmission by a predetermined time difference. The mobile station is set to either the active state or the suspended state in response to the state update data. At the same time, the mobile station is configured to receive the control data and the packet when being set to the active state, and is configured not to receive the control data and the packet when being set to the suspended state.

A sacral support assembly for use with a seat is provided. The seat includes a seat frame. An adjustable sacral support assembly is connected to the seat frame. The sacral support assembly includes a sacral support member adapted to support the sacrum of a seated user. A method is also provided for delivering adjustable, stabilizing support to a user's sacrum and sacral-pelvic anatomy to reduce fatigue, increase comfort, stability and posture for a user, and a system for adjusting and controlling the load distribution from the sacral anatomy to the anatomical structures adjacent to a user's sacrum, for example, the pelvis and lumbar regions.

The present invention provides a permanent-magnet-synchronous-motor having a stator with concentrated windings with the following structure so that permanent magnet (6) is hard to subjected to demagnetization magnetic field: 0.3 Lg<La≦2.0 Lg, where La is a clearance between teeth of stator (1), and Lg is an air-gap between stator (1) and rotor (2). Outer walls of both ends of the permanent magnet (6) disposed within rotor (2) in a rim direction may be tapered toward inside from a rotor rim in a radial direction and to form a recessed section on the outer walls of the magnets. As a result, withstanding force against demagnetization is expected to increase.

A hot rolled steel sheet comprised of, by mass, 0.01 to 0.1% C, 0.01 to 0.1% Si, 0.1 to 3% Mn, 0.1% or less P, 0.03% or less S, 0.001 to 1% Al, 0.01% or less N, 0.005 to 0.08% Nb, 0.001 to 0.2% Ti andthe balance Fe and unavoidable impurities, satisfying the formula ¢Nb! x ¢C!=4.34 x 10<-3>, wherein the density of solid solution C grain boundary quantity is in the range of 1 to 4.5 grain boundaries / nm<2>, and wherein the diameter of cementite grains precipitated on the grain boundaries within the steel sheet is 1 ¢mu!m or less. This hot rolled steel sheet is manufactured according to the following process. A steel piece with the above composition of the hot rolled steel sheet is heated at temperature SRTmin ( DEG C) to 1170 DEG C and subjected to rough rolling in the condition of 1080 DEGto 1150 DEG C finalization temperature. Thereafter, finishing rolling is started at 1000 DEG to below 1080 DEG C within 30 to 150 sec and terminated at temperature ranging from the Ar3 transformation point temperature to 950 DEG C so that the draft upon final pass is in the range of 3 to 15%. The resultant steel sheet is subjected to cooling from the start to the temperature range of 450 DEG to550 DEG C at a cooling rate of over 15 DEG C / sec and wound up.

The present invention is a variable displacement pump having an inner rotor rotatable about a first axis and having at least two slots. The pump also has at least two vanes, each located in a distinct one of the at least two slots. The pump also has an outer rotor rotatable about a second axis, operably associated with the inner rotor, the outer rotor having two or more recesses, each configured to receive one of the vanes. The pump also includes an expandable chamber formed by the outer rotor and the inner rotor, an eccentric ring surrounding the outer rotor, and a housing. The eccentric ring is located within the housing for adjusting the relative relationship between the first axis and the second axis in order to vary the displacement of the pump.

The invention discloses a natural plant sun-screening agent as well as a preparation method and application of the natural plant sun-screening agent. The natural plant sun-screening agent comprises mulberrin, isononyl isononanoate and vitamin E acetate, wherein the weight ratio of mulberrin to isononyl isononanoate to vitamin E acetate is 1:1:1-1:3:3. According to the natural plant sun-screening agent, the mulberrin, the isononyl isononanoate and the vitamin E acetate are compounded to form a stable mulberrin-containing sun-screening agent. The natural plant sun-screening agent and the traditional organic sun-screening agent and an inorganic sun-screening agent have a synergistic interaction function, and therefore, a sun care preparation added with the sun-screening agent is mild in skin and high in safety, and is greatly improved in SPF (Sun Protection Factor) value. The preparation method of the sun-screening agent is simple in process and low in production cost.

A sacral support assembly for use with a seat is provided. The seat includes a seat frame. An adjustable sacral support assembly is connected to the seat frame. The sacral support assembly includes a sacral support member adapted to support the sacrum of a seated user even when an obstruction is located between the user and the sacral support assembly. A method is also provided for delivering primary support to a user's sacrum and sacral-pelvic anatomy and secondary support to the remaining regions of the spine and / or adjacent anatomy to reduce fatigue, increase comfort, structural balance, stability, and posture control for a user, and a system for adjusting and controlling the load distribution from the sacral anatomy to the spine and other anatomical structures adjacent to a user's sacrum, for example, the pelvis, lumbar, thoracic and cervical regions.
