Abstract: A method is provided for producing a display item. Display item parameter data and user input data are received. A design prompt is generated based on the data. User uploads such as photos and other documents are also received. A personalized display item design is generated based on the design prompt and user uploads. The generated design is refined based on pre-defined system constraints. User feedback is received on the refined design. The display item design is further refined based on the user feedback. The design is refined iteratively based on the user's feedback as well as the pre-defined system constraints until the user approves the design. The display item is manufactured based on the display item design approved by the user.

Abstract: A dielectric-based 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 with a transmit filter. The housing further includes a receive path with at least one receive filter and a low noise amplifier. 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: 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.
