  • Patent number: 8451185
    Abstract: A multi-feed dipole antenna and method. Provides a volumetrically efficient antenna with wide radiation pattern bandwidth and wide impedance bandwidth that are relatively independent. Driving the antenna at multiple locations provides for a half wavelength dipole antenna with a wider frequency range than any other known fat dipole of similar volume. The apparatus is constructed from brass or any other suitable metal without requiring dielectric loading and without requiring direct coupling on the outside of the tubes. The apparatus utilizes a parasitic center tube with two end tubes that are driven by a collinearly mounted metal rod that is driven from the midpoint. Insulators hold the parasitic tube to the end tubes. The parasitic tube allows for induced currents to flow on the surface of the tube which allow for operation of the dipole over a wide frequency range.

  • Patent number: 8074890
    Abstract: A flexible antenna capacitively coupled to related circuitry components for an active wearable data transceiver electronic location and identification device. Wearable data transceivers (WDXs) are employed as bracelets, badges, and may be incorporated with back pack straps and clothing at locations such as collars, cuffs, and hems. They employ various colors. Active transceiver communication devices are also mounted on objects for real time location tracking and identification. Body-mounted WDXs match the body with the antenna for sending and receiving signals. WDX power includes coplanar battery cells and circuitry has radio transmitter and radio receiver components.

  • Patent number: 7362285
    Abstract: A compact antenna for use in a device for controlling the power delivered to an electric load and operable to transmit or receive radio frequency signals at a specified frequency is presented. The antenna comprises a first loop of conductive material having a capacitance and an inductance forming a circuit being resonant at the specified frequency, and a second loop of conductive material having two ends adapted to be electrically coupled to an electronic circuit. The second loop is substantially only magnetically coupled to the first loop and is electrically isolated from the first loop. In a first embodiment of the antenna, the first and second loops are formed on respective first and second printed circuit boards, which allow for a small, low-cost antenna that is easy to manufacture and maximizes efficiency. When the antenna is installed in a load control device, such as a dimmer, the first loop of the antenna is mounted on an outer surface of the device.

  • Patent number: 5124648
    Abstract: A magnetometer having only a single coil winding for sensing the magnetic field along a single axis. Functionally, the invention comprises an oscillator, an integrator, and a voltage-controlled current source. The oscillator uses a saturating inductor which also serves as the magnetic-field-sensing element. The inductor is driven with a positive voltage and when the current through the inductor exceeds a value which indicates that the core is saturated, the driving voltage switches to an equal-magnitude negative value. This negative drive is maintained until the current again indicates the core to be saturated, at which point the driving voltages switches back to the positive value. With no externally applied field, the inductor current averages to a zero value. An externally applied field helps the core saturate in one direction and hinders it in the other, resulting in a change in average inductor current.

  • Patent number: 5039945
    Abstract: The effects of non-equal saturation spikes in a magnetic oscillator magnetometer utilizing a magnetic core sensing inductor are compensated by adding the average inductor current to both the high and low current magnitude limits. In particular, each of the current limits is selected to be a fixed current (which is greater than that required to saturate the core) offset by the average current flowing in the core.The effects of magnetic core hysteresis and series resistance between the inductor and its drive sources are compensated by controlling the drive voltage levels so that the time during which the inductor is driven by current in one direction is equal to the time during which it is driven by current in the other direction.

  • Patent number: 4859944
    Abstract: A magnetometer having only a single coil winding for sensing the magnetic field along a single axis. Functionally, the invention comprises an oscillator, and means for measuring the duty cycle thereof. The oscillator uses a saturating inductor which also serves as the magnetic-field-sensing element. The inductor is driven with a position voltage and when the current through the inductor exceeds a value which indicates that the core is saturated, the driving voltage switches to an equal-magnitude negative value. This negative drive is maintained until the current again indicates the core to be saturated, at which point the driving voltages switches back to the positive value. With no externally applied field, the inductor current averages to a zero value and the duty cycle of the driving voltage is fifty percent. An externally applied field helps the core saturate in one direction and hinders it in the other, resulting in a change in average inductor current and drive duty cycle.
