Abstract: A connector is described of the type that has contacts lying in insulative material in a housing, wherein a separate positioner (24 in FIG. 2) of insulative material is molded about each contact (22) to form a terminal device (20), and the terminal devices can be arranged in a variety of configurations. Each terminal device includes an elongated metal contact with front and rear end portions and a middle, and an insulative positioner (24) molded about the middle. The terminal devices lie in the housing with the molded positioners of adjacent contact devices substantially abutting each other and holding the contact ends in a predetermined pattern, wherein the axes of all terminal devices extend parallel to each other. The middles of the contacts are hollow and include access openings (52 in FIG. 5) into which molding material can flow, so the molded material of the positioner seals the middle of the inside of each contact.

Abstract: A contact assembly for installation in an electrical connector, provides effective electromagnetic filtering in a simple, compact, and rugged construction that facilitates in-field replacement of a damaged contact assembly. The contact assembly includes a signal conductor, a diode for diverting high voltages on the signal conductor to ground, and a "pi" filter for filtering out unwanted frequencies. The "pi" filter includes a ferrite bead inductor coupled to the signal conductor and a first capacitor coupling a location of the signal conductor on a first side of the inductor to ground. The other capacitor of the "pi" filter is formed by the capacitance of the diode, with the diode connected to a signal conductor location on a second side of the inductor, and with the capacitance of the diode similar or equal to that of the first capacitor.

Abstract: A mailbox signaling arrangement cooperably responsive to pivotal movement of the entry lid of a common rural mailbox characterized by a pivotal signal plate member and, optionally, the selective energization of a light source. Operation of the signaling arrangement is occasioned by the release of the aforesaid signal plate member (which is continually urged to a signaling position) as a result of entry lid movement, with the signal plate member also initiating operation of the light source when at such signaling position.

Abstract: A radio frequency modulator/demodulator (modem) and method for receiving and transmitting data over a radio frequency data link. The modem has a transmitting section which includes a modulator which modulates a radio frequency signal in response to data provided by, for example, an associated processor. The transmitting section further includes a watchdog or enable circuit which monitors a request-to-send signal produced by the associated processor, with the request-to-send signal being present when the processor is generating data to be transmitted over the data link. The enable circuit will disable the modulator should a transmission exceed a maximum predetermined time period, thereby preventing the associated processor from monopolizing the data link in the event of a processor failure.
