  • Patent number: 10897182
    Abstract: A power producing apparatus includes a stator portion having a stator ring disposed proximate a housing of a turbine engine. The stator potion further includes a plurality of coils. A rotor portion includes a rotor ring having a plurality of permanent magnets disposed coaxial to the plurality of coils, and the permanent magnets are oriented with alternating polarity. Individual or a plurality of coils are configured to be selectively moved axially with respect to the rotor ring.

  • Publication number: 20050116575
    Abstract: An electrical machine using a plurality of separate teeth that can be axially inserted into a stator ring or armature after receiving a bobbin or form wound coil. Each tooth contains a primary locating structure and a secondary locating structure which respectively set the radial position and the angular position of the teeth in a stator ring. This construction can also be used with internal motor armatures. The primary and secondary locating structures have a size equal to or smaller than the portion of the tooth that holds the coil. This allows insertion of a pre-wound coil over these features without interference. The use of separate stator or armature teeth that are press fitted into the stator ring or armature allows the use of coil types that could not be inserted into a one piece stator or armature and tooth materials with optimum magnetic properties.

  • Patent number: 6104337
    Abstract: A golf distance indicator system provides measurement and display of the distance between a golfer and the pin on the green he is approaching. The system comprises a portable unit carried by the golfer and an target unit located on the pin. With the portable unit, the golfer selects the hole he is playing then activates the system. The portable unit sends a wireless coded message to an intended target unit. When a target unit receives a message, it analyzes the message to see if it should respond. If the target unit determines that it should respond, it sends a coded responding message to the portable unit. When the portable unit receives a responding message, it analyzes the responding message to see if the responding message originates from the intended target unit. If it does, the portable unit calculates a distance based on the elapsed time for the communications and the speed of the communications. The results are displayed on the portable unit.

  • Patent number: 5247700
    Abstract: A compact and unitary cellular/pager. The cellular/pager includes a cellular antenna for receiving UHF cellular and paging signals. The cellular/pager also includes a VHF paging antenna. Every paging signal is sent to a paging receiver. The paging receiver uses the same circuitry to process either the UHF or VHF page. This is accomplished by setting a voltage controlled oscillator (VCO) to one of two frequency ranges. The chosen frequency is either added or subtracted to the incoming signal in order to match a constant intermediate frequency. The resultant signal is demodulated and a bit rate is selected by a decoder, under the control of a microprocessor. Therefore, the paging receiver can choose a band, a channel and a bit rate. Cellular signals are sent to a cellular block. Cellular location information is utilized by the cellular/pager to form an internally updated roaming pager.
