Abstract: An optical fiber support member is made by forming on a monocrystalline silicon substrate member (26) a first mask layer (27) of, e.g., silicon dioxide. The first mask layer is masked and etched to a first depth to define a pattern of first (29) and second (30) features, the first features defining the locations of optical fiber support grooves (15), and the second features defining the locations of support member reference surfaces (17, 19). Next, only the second features are etched to a second depth deeper than the first depth. Finally, the first and second features are simultaneously etched into the substrate such that the second features are etched to a greater depth than the first features. By defining the first and second features simultaneously in a single mask and etch step, one can assure the final precise alignment of etched V-grooves to etched reference surfaces.

Abstract: A circuit for cutting off power to selected components in a network which requires that backup power be supplied to other components. A monitoring signal is generated and combined with the power coupled to the components. A signal detector in the selected components determines the absence of the monitoring signal which is indicative of a commercial power outage. The signal detector then activates a cutoff mechanism which cuts off a portion of the component from the backup power without obstructing the flow of power and of the monitoring signal to the output of the component so power may be used by other downstream components.

Abstract: Disclosed is a connector module which protects adjacent contacts from being shorted by condensation. Ridges are provided on a housing adjacent each contact such that water droplets of a sufficient width to bridge the distances between contacts cannot form.

Abstract: Disclosed is a circuit and system for preventing tampering with services provided in a broadband transmission network. A coaxial relay is coupled between a cable providing signals in the network and the drop cable to the customer's premises. The coil which operates the relay is coupled to the shield conductor of the drop cable and to a source of dc potential. As long as a current flows through the shield portion and the coil, the customer is connected to the network through the relay. If current stops, as when the customer disconnects the drop cable, the customer is disconnected from the network.

Abstract: Disclosed is a cabinet for housing electronic equipment. The cabinet includes a sealed first portion enclosing circuit packs such as those used for broadband and narrowband telecommunications transmission. The second portion is ventilated and encloses electrical components such as coaxial cable hardware.

Abstract: Optical fiber support members (30 and 31) are formed by making an array of V-grooves (25) in a monocrystalline material (26), depositing metal (27) on the array, and removing the metal member to provide an insert. The insert is used to form the support members by injection molding.

Abstract: Disclosed is a voltage and current protector device designed for connecting blocks with a high density of contacts. Thermal overload protection is provided through a special ground connector with one end mounted over the surge protector element rather than through the normal ground pin of the element. The ground connector at its other end is shaped into a detent for capturing the ground bar of the connecting block.

Abstract: Disclosed is a connector module which permits termination of cross-connect wires on one surface and cable wires on an opposite surface. The module exhibits a generally "Z" shaped configuration which permits test access, jumper insertion, and protector mounting on either surface.

Abstract: An electronic device (12, 13) is substantially enclosed by a fluid encapsulant (17). The fluid encapsulant consists essentially of a silicone resin and a catalyst selected from the group consisting of platinum and tin. The silicone resin is selected from the group consisting of polydimethlysiloxane, polymethylphenylsiloxane, polydimethyldiphenylsiloxane, and mixtures thereof. Such silicone resins comprise molecules terminating in vinyl components and hydride components. The molar ratio of vinyl components to hydride components is maintained within the range of five to twenty. As will be explained more fully later, this ratio of vinyl components to hydride components assures that the resin will remain substantially a liquid even after cure, due to limited cross-linking or polymerization during the cure. The electronic device is contained within a container (16) having a sealed cover (18) for containing the liquid encapsulant during the operation of the electronic device.

Abstract: According to the present invention, an improved CDMA receiver for receiving spread-spectrum-modulated signals is provided. In the improved receiver, a multicarrier signal processor is positioned. The multicarrier signal processor includes a controller for analyzing an incoming multicarrier signal. At least one signal modifier communicates with the controller, such that the controller directs signal modifier to attenuate at least one carrier signal which is not spread-spectrum-modulated. More particularly, the present invention provides an apparatus for attenuating carrier signals in a multicarrier signal which includes at least one spread-spectrum-modulated signal and other carrier signals. The apparatus comprises a receiver for receiving a multicarrier signal which includes at least one spread-spectrum-modulated signal and other carrier signals.

Abstract: The present invention provides enclosures for protecting equipment, particularly electrical equipment, from electromagnetic interference. The enclosure includes at least two EMI-shielding portions which, when assembled, at least partially enclose a piece of equipment to be shielded. The first EMI-shielding portion of the enclosure is provided with a first interlocking element. The first interlocking element is integrally formed with the first EMI-shielding portion. A second EMI-shielding portion of the enclosure includes a second integrally-formed interlocking element. The first and second interlocking elements connect the first and second EMI-shielding portions of the enclosure such that electromagnetic energy is not transferred through the connected first and second interlocking elements at a substantially greater rate than through the remaining portions of the enclosure.

Information is modified by adding a new block of data at another location in the memory rather than writing over the outdated information. An address pointer locates the latest information for each data file.

The stem portions of the contacts make physical and electrical contact at two points which are aligned with slots in the module so that one point remains closed while one point opens due to lead insertion.

Abstract: The invention is an improved optical fiber connector of the type comprising two identical plastic support members (11) having therein at least one V-groove on a first surface. The two support members are identical, with the V-grooves (12) being adapted to clamp on opposite sides of an optical fiber (16). In one embodiment of the invention, each of the support members has integrated therein a first spring member (20). First and second alignment pins (17, 18) are located on opposite sides of the matched first and second support members (11). The spring member (20) of a first one of the support members bears against one of the alignment pins (18) and forces it against the first and second support members (11); and the other spring member (19) forces the other one of the alignment pins (17) against the first and second support members. The springs are both preferably leaf springs which extend in a direction parallel to the V-grooves.
