Abstract: Systems and methods for sponsoring an area of land are disclosed. Certain systems and methods may cause the display of areas of land that are available for sponsorship, receiving input identifying an area of land to sponsor, processing sponsorship of the identified area, and generating an interface for displaying the sponsored area.

Abstract: A power control circuit is provided for coupling a load to a power source. It includes a transistor for coupling said load to the power supply through the transistor dependent upon a control voltage applied to a control terminal of the transistor, a charge pump circuit having its output connected to the transistor control terminal to apply a controlled turn on signal to the transistor when the charge pump is activated, wherein the controlled signal gradually increases until the transistor is biased into its fully on state.

Abstract: An adaptor for a honey extractor which is normally manually operable by hand cranking a drive shaft allows it to be operated by a power drill. The adaptor engages the drive shaft axially of the honey extractor after removal of the handle which is used fo manual operation to connect the drive shaft to a power drill. The adaptor is conveniently a socket to engage an end of the drive shaft,the socket having a prong for insertion in the chuck of a power drill.

Abstract: A femoral-side hip-joint prosthetic device for use in hip-joint replacement. The device includes an elongate stem whose surface defines maximally spaced infero-medial and supero-lateral surface curves, and which is characterized by a surface rotation which carries the supero-lateral surface curve about 15.degree.-30.degree. forward with respect to the infero-medial surface curve, on progressing upward along the upper surface portion of the stem, with the device in operative position. The rotation of the stem surface produces a close approximation to the cavity formed in the proximal femur by removal of the cancellous bone in the natural cavity formed by a wall of densified cancellous bone. A 3.degree.-15.degree. proximal anteversion of the neck is adapted to place a hip-joint ball carried on the stem at a position closely approximating that of the head in the natural femur.

Abstract: An improved tibial component is provided for a knee prosthesis, wherein the tibial component includes a pair of tibial tray members adapted to accommodate independent longitudinal shifting during patient function while retaining a secure and stable fixation with respect to patient bone. The two tibial tray members comprise medial and lateral members for supporting the medial and laternal condyles of a knee joint. These tray members are interconnected by a slide key arrangement which restrains the tibial tray members against relative movement in the anterior-posterior and medial-lateral directions, while permitting relative shifting in a longitudinal direction corresponding generally with a central axis of the patient's tibia. In the preferred form, the two tibial tray members cooperatively define a common anchoring post and include one or more antirotation fins for mechanically locking with patient bone.

Abstract: A femoral-side hip-joint prosthetic device for use in hip-joint replacement. The device includes an elongate stem whose surface defines maximally spaced infero-medial and supero-lateral surface curves, and which is characterized by a surface rotation which carries the supero-lateral surface curve about 18.degree.-30.degree. forward with respect to the infero-medial surface curve, on progressing upward along the upper surface portion of the stem, with the device in operative position. The rotation of the stem surface produces a close approximation to the cavity formed in the proximal femur by removal of the cancellous bone in the natural cavity formed by a wall of densified calcellous bone. A 3.degree.-15.degree. proximal anteversion of the neck is adapted to place a hip-joint ball carried on the stem at a position closely approximating that of the head in the natural femur.

Abstract: A scanning pyrometer for measuring the temperature of moving material having a plurality of separate components has an oscillating mirror in an optical system focusing thermal radiation from the moving material on a thermal radiation detector. Temperature is determined by circuitry providing an electrical signal representative of the peaks of the pulses output of the detector.
