  • Patent number: 9590160
    Abstract: The invention relates to a thermoelectric-based power generation system designed to be clamped onto the outer wall of a steam pipe or other heating pipe. The system can include a number of assemblies mounted on the sides of a pipe. Each assembly can include a hot block, an array of thermoelectric modules, and a cold block system. The hot block can create a thermal channel to the hot plates of the modules. The cold block can include a heat pipe onto which fins are attached.

  • Publication number: 20150190234
    Abstract: A Midlay component includes a plastic bearing part and a metal tray part. The upper surface of the bearing part is dished in frontal and sagittal planes, to provide a bearing surface, such that in function, the femoral contact point will remain in the central region of the bearing surface. Hence the load-bearing on the plastic bearing part will be above the thickest portion in the central region. The metal tray part features a tray-bottom that enables retention of strong cortical and cancellous portion of a tibia in the treatment of osteoarthritis of a knee joint, and supports the plastic bearing part, with the rim of the metal tray part maintaining the position of the plastic bearing part and minimizing micromotions.

  • Publication number: 20050192584
    Abstract: A bone surgery device with a reciprocating cutting head. The device comprises several sets of shaping surfaces sometimes including cutting blades, which are located and oriented so as to shape the distal end of the femur and the proximal end of the tibia for total knee replacements and unicompartmental knee replacements. The device, which may be hand directed or aided by spatial and directional guiding mechanisms or an optical navigation system, may also include both coolant supply for controlling heat during bone cutting and shaping, and a suction method for carrying away fluid and debris. The device is substantially configured to the artificial joint component to be attached thereto.

  • Patent number: 6022314
    Abstract: A method for operating an electronic apparatus so as to produce an automated display of date and time specific biorhythmic acupuncture points is disclosed. The method monitors a current Gregorian-calendar date and time generated by the electronic apparatus, converts it into a Chinese-calendar Kan-day and Chih-period index affiliated with a biorhythm, utilizes the index to indicate and retrieve a biorhythmic acupuncture point from a table of predetermined biorhythmic acupuncture points, and displays the retrieved biorhythmic acupuncture point and current date and time. Once started, the method continues to display and update current date and time and their corresponding biorhythmic acupuncture point until it is interrupted by a user of the electronic apparatus.
