Patent number: 8175757Abstract: A temperature control system and methods that remove dust or debris from inside an electrical equipment chassis are provided. One or more fans are placed in or near the exterior of the chassis. The fans are operated either in reverse, forward, pulsing, or reverse pulsing modes to create turbulent air flow through the chassis. The change in air flow pattern helps dislodge dust and particles. Once airborne, the fans can exhaust the dust and particles. Further, some embodiments provide vanes or other elements to further direct air flow. The temperature control system can be used in any electrical equipment that is ventilated with fans. The temperature control system provides the advantage of a low cost and efficient method for ensuring that dust does not accumulate on components within an enclosure.Type: GrantFiled: September 10, 2009Date of Patent: May 8, 2012Assignee: Avaya Inc.Inventors: Trevor J. Aggus, Helane F. Daniels, Linda Derechailo, Richard Jaccard, Roman Kelbert, Steve Mak, Charles Truax, Niv Zilberman

Patent number: 6322175Abstract: A circuit card enclosure formed of sheet metal with its top and bottom walls having integrally formed circuit card guides. The guides are lanced and formed projections extending inwardly from the top and bottom walls and are spaced from the respective walls by a distance satisfying regulatory requirements for sizes of opening in such enclosures. Additionally, the top and bottom walls have apertures for heat dissipation purposes which likewise satisfy the regulatory requirements. Thus, the enclosure does not require an additional top cover or shield.Type: GrantFiled: December 29, 1999Date of Patent: November 27, 2001Assignee: Avaya Technology Corp.Inventors: Trevor J. Aggus, Matthew J. Gawron

Patent number: 6191953Abstract: Structure for mounting a circuit card to a sheet metal wall includes upper and lower standoffs formed integrally with the wall. Each upper standoff extends a predetermined distance from the wall and is adapted to receive and hold a fastening member. Each lower standoff is formed integrally with the wall and includes a projection portion extending the same predetermined distance away from the wall and a hook portion having a support portion extending away from the projecting portion and a securement portion extending upwardly from the support portion and spaced from the projecting portion by a distance equal substantially to the thickness of the circuit card. Accordingly, a lower edge of the circuit card is supported by each lower standoff hook portion and fastening members are extended through holes in the circuit card to threadedly engage the upper standoffs.Type: GrantFiled: December 29, 1999Date of Patent: February 20, 2001Assignee: Avaya Technology Corp.Inventors: Trevor J. Aggus, Matthew J. Gawron

Patent number: 6088447Abstract: A telephone instrument is disclosed which includes a swivel visual display module overcome by employing a telephone base having upper and lower housings. A swivel visual display module is pivotally mounted and supported by pivot points in both the upper and lower base housings. At least one cantilever snap member is molded into one of the base housings, for example, the upper base housing, and is employed to engage indents molded into an outer convex surface of the visual display module to hold the visual display module in several angular positions. Additionally, the at least one cantilever snap member is employed to engage a lower edge of the visual display module and in conjunction with stop members on the visual display module to secure the visual display module in a full upright position.Type: GrantFiled: March 14, 1997Date of Patent: July 11, 2000Assignee: Lucent Technologies Inc.Inventors: Trevor J. Aggus, George A. Kopacz, Steve Oliver Mak, Mark Edward Millman, Bobbie Jo Ridgely

Patent number: 6053747Abstract: A circuit board connection device and method for use in an assembly having a first portion and a second portion, wherein a first circuit board is contained within the first portion of the assembly and a second circuit board is contained within the second portion of the assembly. A flat cable is connected to the second circuit board. The flat cable is flexible, yet is rigid enough to support its own weight. Consequently, the flat cable extends upwardly from surface second circuit board and terminates at a free end. A flat cable connector is provided on the first circuit board. The flat cable connector is sized to receive the free end of the flat cable. An alignment collar is placed over the flat cable connector. The alignment collar receives the free end of the flat cable and guides the free end of the flat cable into the flat cable connector as the first portion of the assembly is assembled to the second portion of the assembly.Type: GrantFiled: September 8, 1998Date of Patent: April 25, 2000Assignee: Lucent Technologies Inc.Inventors: Trevor J. Aggus, Matthew John Gawron, George A. Kopacz

Patent number: 5907612Abstract: A button which is removable from and insertable into a keypad from the exterior of a housing containing the keypad. The button fits within an opening of the keypad and is formed with resilient fingers in its side walls. The fingers have interfering flanges at their lower ends. The flanges are chamfered to provide a camming action to deflect the fingers when the button is removed or inserted.Type: GrantFiled: February 27, 1997Date of Patent: May 25, 1999Assignee: Lucent Technologies Inc.Inventors: Trevor J. Aggus, Bobbie Jo Ridgely

Patent number: 5862214Abstract: A telephone base includes a base module and a rotatable base stand module. The base module may be elevated to a plurality of inclined positions by employing in the base stand modules the plurality of cantilever snap members each of which has a protruding locking member. The telephone base module includes a plurality of locking apertures which correspond to the locking members on the cantilever snap members. The desired inclined positions are obtained by rotating the base module around pivot elements in the base stand module and inserting the locking members on the cantilever snap members into appropriate ones of the locking apertures in the base module. Additionally, the base stand module may be rotated and locked in place to the base module by additional locking members to orient the telephone base for wall mounting. Advantageously all the elements required for the above features are integrally molded into the base module and the base stand module.Type: GrantFiled: November 9, 1995Date of Patent: January 19, 1999Assignee: Lucent Technologies Inc.Inventors: Trevor J.
