Abstract: The heads interface with a conventional handpiece so that the facial brush or other facial treatment head can be removed and replaced with a subassembly that provides pivoting/floating support. The treatment head is then attachable to the pivoting/floating subassembly as if it were attaching to the handpiece; the result being a motorized skin treatment head that pivots and/or floats to follow the contour of the skin. The internal motor can either be housed within the handpiece, or pivoting/floating subassembly, and will either provide rotation/oscillation of the treatment head, or simple vibrations to the handpiece and/or treatment head. The floating mechanism may be available in a variety of forms to provide the widest variety of use scenarios. Each floating mechanisms and/or subassemblies are interchangeable with the others so as to be removably attachable to the handpieces described in the Parent applications.

Abstract: The device combines the detangling capability of a comb or brush with the ability to massage lotions and other hair treatments into the hair follicles and through the entire length of each hair strand. A two-jaw clamping or clamshell design is provided with an interchangeable brush or comb element attached to one of the jaws and a pair of soft rollers extending from the other jaw element. The two jaws are detachable from one another in order to permit the user to operate the comb or brush portion separate from the rollers. When fully assembled, the comb or brush protrudes through the pair of rollers when the jaws of the device are clamped together. There may be an additional mechanism within the device to provide internal vibrations in the housing to propagate through the entire device and into the user's hair in order to aid in the detangling, smoothing and treatment application processes. One or more additional versions may also include vibrating or oscillating rows of bristles in the brush or comb element.

Abstract: An Optical channel Data Unit flex (ODUflex) resizing method, node, and network include determining that the ODUflex needs resizing, wherein the ODUflex is configured in the network on a current path between the node and a second node in the network; when the resizing is a decrease, reducing a size of the ODUflex by i) a resize decrease operation using a control plane or ii) a Link Aggregation Group and Make-Before-Break operation; and, when the resizing is an increase, increasing a size of the ODUflex by i) a resize increase operation using a control plane or ii) a Link Aggregation Group and Make-Before-Break operation. The method provides hitless resizing without using ITU Recommendation G.7044/Y.1347 (10/11) and can perform the reducing or the increasing changing bandwidth of the ODUflex by approximately 100 G in less than a second.

Abstract: A handheld facial massage and microcurrent therapy device. The device includes a massage feature that enables the user to provide motorized agitation to a skin-contacting attachment selected from a group of detachable elements. The detachable skin-contacting element includes bristle brushes, massage sponges, smooth and rough applicators, among others. In addition to the motorized agitation from the attachment, the device also includes the ability to apply rejuvenating micro-current therapy to the skin. Both the motorized agitation and micro-current generation are independently user-adjustable in order to achieve the optimum treatment for each individual. Versions of the device that include galvanic current application as well as ultrasonic skin stimulation are available. The device is compact and easy to use so that the non-professional user can self-treat with professional results.

Abstract: A four-bar linkage is provided as a mechanical interface for transferring respective outputs from a speed/direction control device and a hydraulic steering cylinder to displacement control arms of a pair of pumps of a dual-path hydrostatic transmission including a pair of motors respectively coupled for driving a pair of front wheels of a vehicle. The hydraulic steering cylinder is fixed and has a piston rod slidably coupled to an input arm of the four-bar linkage in such a way that a rotation speed decrease occurs as the arm and a linked control plate are pivoted from a neutral position, the control plate transferring pivotal movement to effect differential movement of the displacement control arms. This results in the vehicle speed decreasing during a turn.
