Abstract: An improved regulator system is disclosed for controlling a field winding of an alternator to regulate the charging of a battery. The improved regulator system comprises an internal regulator mounted onto the alternator. The internal regulator has an internal regulator control circuit for monitoring the battery and for controlling the field winding. An electrical connector actuates the internal regulator to regulate the output of the alternator in accordance with the internal regulator. The electrical connector enables an external regulator to be connected to the alternator thereby bypassing the internal regulator to regulate the output of the alternator in accordance with the external regulator. The improved regulator system facilitates the connection of an upgrade external regulator with the internal regulator functioning as a reserve regulator in the remote event of a malfunction of the external regulator.

Abstract: A RF device such as a tower mounted amplifier (TMA), mast-head amplifier (MHA), or Tower Mounted Boosters (TMB) includes a housing having a plurality of cavities and an input and an output, the input being coupled to the antenna and the output being coupled to a base station. The housing includes a transmission path holding multiple coaxial resonators. The housing further includes multiple receive paths including at least one path having a plurality of cavities, each cavity containing a dielectric resonator. The metallic transmit resonator nearest the antenna input is coupled to the first dielectric resonator via a common resonant wire. The last dielectric resonator in the receive path is coupled to a first metallic resonator of a downstream clean-up filter via another common resonant wire.

Abstract: A dielectric-based filter includes a thermally insulated housing, at least one filter formed from a dielectric material disposed inside the insulated housing, and a temperature maintenance device having a heating component and a cooling component for maintaining the temperature of the filter inside of the insulated housing within a temperature range. In a preferred aspect of the invention, the temperature maintenance device includes a thermoelectric cooler. The device permits the use of temperature-dependent low loss, high dielectric constant materials in filtering/resonator applications. During operation of the device, the dielectric-based filter is maintained at substantially room temperature.

The receive filter includes a plurality of cavities with a dielectric-based resonator disposed in at least some of the plurality of cavities. In one aspect, the RF device has a volume of less than about 155 in3. The RF device including the dielectric-based resonators has excellent out-of-band signal rejection with low loss. In addition, the RF device described herein is small enough to mount close to the antenna. The dielectric-based RF device has superior performance characteristics and a smaller footprint than conventional air cavity-based TMAs.

Abstract: Methods, apparatus, and systems are provided for remoteable communication systems. More particularly, the inventions of this system include a remoteable or distributed communications system having a plurality of front ends located remotely from a base station. Each front end includes a receive side subsystem with an HTS filter, a non-linear modulator, and may also include a low noise amplifier coupled to the non-linear modulator. The non-linear modulator modulates a RF signal in light prior to transport via an optical transmission path to the base station. Because the modulator is placed in the front end, no down conversion is required prior to transport of a received signal.

Abstract: An optical occluder adapted for use with monocular optical instruments having a variety of shapes and sizes, for blocking the vision the user's eye that is not looking through the instrument. The occluder includes a central retainer body to which are attached both a generally planar eye shield and a elastic cord of adjustable length. The cord can be selectively wrapped around an optical's instrument's eyepiece, to hold the occluder in a stable position relative to it, and the eye shield can be selectively positioned both radially and circumferentially relative to the central retainer, to suit the user's particular eye spacing and comfort.

Abstract: A perpetual monthly calendar for showing the numerical days of any month related to the proper days of the week comprising a rigid planar surface having a plurality of pegs spaced apart in a horizontal line disposed near the upper edge of the surface and a plurality of vertically positionable rigid strips bearing columnized numerical indicia indicative of particular numerical days, each strip removeably coupled to a different peg. Displayed on the planar surface adjacent each peg are indicia correlating a particular peg to a particular day of the week. The numerical indicia on each strip is displayed in column form, displaying the appropriate numbered sequence one week apart. Each strip has a pair of vertically disposed apertures (except the strip having the first day of the month, which has a single aperture), each of which may receive a peg to mount the strips vertically on the board. A particular monthly numeral-day array is achieved by positioning the strips relative to the pegs.
