Abstract: The present disclosure relates to a telecommunication device including an enclosure configured to be mounted to a telecommunication rack. The device also includes a tray that mounts within the enclosure, the tray being slidably movable relative to the enclosure along a front-to-rear axis between a first position and a second position. The tray is fully within the enclosure when in the first position. A forward portion of the tray projects forwardly from the front end of the enclosure and a rearward portion of the tray is within the enclosure when the tray is in the second position. A spool mounts on the tray and is moveable with the tray as the tray is moved between the first and second positions. The spool being rotatable relative to the tray and the enclosure to allow cable to be paid out from the spool at least when the tray is in the second position.

Abstract: A removable facial interface for a head-mountable device (HMD) is disclosed. In an example, an HMD includes a display; a facial interface frame at least partially surrounding the display; a removable facial interface attached to the facial interface frame; a first attachment mechanism attached to one of the facial interface frame or the removable facial interface; and a second attachment mechanism attached to the other of the facial interface frame or the removable facial interface, the removable facial interface being attached to the facial interface frame by the first attachment mechanism and the second attachment mechanism.

Abstract: A rib post (10) has a hollow substantially triangular cross-section comprising composite material. The rib post (10) can form a structural member to join two adjacently placed components together, for example a spar and internal rib in a wing of an aircraft. The rib post (10) can be formed from first (12), second (14) and third (16) walls. The first wall (12) can abut a surface of one component and the second wall (14) can abut a surface of a second component. The first and second walls (12, 14) can be attached to the respective components, such as a rib and spar, to join them together. The third wall (16) joins together the first and second walls (12, 14) to form the hollow triangular section.

Abstract: A skin grooming device comprising a planar surface for removable attachment to a stationary surface, having affixed thereto an undulating abrasive block for use in abrading rough, dead, or dry skin from keratinous surfaces and a method for grooming skin using the device.

Abstract: A high frequency microelectronic package suitable for high-frequency microelectronic devices includes a base which is at least partially conductive and attached to an RF substrate with a cavity formed at its center. The base may be metal or ceramic with a metal layer deposited thereon. A pattern of conductive paths for providing interconnection from the inside to the outside of the package are formed on the surface of the RF substrate. These conductive patterns are designed to have a constant impedance when uncovered, regardless of the dielectric property of the material used to cover the conductive patterns. Namely, a sealing cap or a lid, made from a variety of dielectric materials, may be attached to the RF substrate by a non-conductive adhesive, such as a polymer adhesive or low temperature seal glass, to seal the package once the microelectronic device has been mounted inside.

Abstract: A fiber data distributed interface (FDDI) system uses an MLT3A encoding scheme in order to reduce DC bias or baseline wander. The MLT3A encoding scheme is a scheme wherein logical zeros are transmitted as ground voltages and logical ones are transmitted as one of either positive voltages or negative voltages depending upon past transmission history (FIG. 4 ) wherein the past history is recorded by a counter C or an analog circuit. MLT3A ensures that the baseline wander or DC bias returns to zero or is maintained as close to zero as possible in a timely manner so that no FDDI systems will fail from baseline wander.

Abstract: An integrated circuit for use in fiber distributed data interface (FDDI) system has four elastic layer and buffer management (ELM) circuits (12, 14, 16, and 18) coupled through a crossbar switch (20). The crossbar switch (20) allows any of the ELM circuits (12, 14, 16, and 18) to be coupled to any other ELM circuit (12, 14, 16, or 18) or to one of three external buses for FDDI communication. By using a crossbar switch and four ELM devices on a single integrated circuit, FDDI performance is improved while system design is made easier and more flexible than previously possible. Cipher circuitry (22, 24, 26, and 28) is used to scramble and descramble data ingoing and outcoming from the ELM devices. Concentrators, workstations, local area networks (LANs), and the like may incorporate the circuit (10) to improve performance and flexibility.

Abstract: A bicycle frame supports a sprocket, front and rear wheels and first gears axially aligned with the rear wheel. Each gear has an individual ratio with the sprocket. At a first end, a support is attached to the frame at two (2) spaced positions, one axially aligned with the rear wheel. When loosened from the frame at such aligned position, the support is pivotable at the other position to provide access to the rear wheel and the gears for maintenance or repair. At its second end, the support holds a hollow shaft in a direction substantially parallel to the gear peripheries. A drive motor, a screw and a yoke mounted on the screw extend in this parallel direction within the shaft. Channels in the shaft receive the yoke to constrain yoke rotation. The motor drives the screw and yoke to position a spool linearly in the parallel direction. A takeup arm movable with the spool carries an additional gear into alignment with an individual one of the gears.

Abstract: A ceramic microelectronic package suitable for high-frequency microelectronic devices includes a base which is at least partially conductive attached either by seal glass or by solder to a ceramic RF substrate with a cavity formed at its center and a pattern of conductive paths for providing interconnection from the inside to the outside of the package. The base may be metal or ceramic with a metal layer deposited thereon. A ceramic seal ring with a second cavity corresponding to that of the RF substrate, but slightly larger, is attached to the RF substrate by seal glass which is patterned to generally match the dimensions of the seal ring. A ceramic lid is attached to the top of the seal ring by a non-conductive adhesive, such as a polymer adhesive or low temperature seal glass, to seal the package once the microelectronic device has been mounted inside.
