Patent number: 7016138Abstract: Tape drive systems and methods for operating tape drive systems are provided. The system includes a head assembly having a head element for reading or writing data to a magnetic tape medium, and a pressure sensor coupled to the head element, the pressure sensor configured to generate a pressure signal representative of a pressure applied by the head element onto the pressure sensor. In some embodiments, an accelerometer is provided for sensing an acceleration of the head assembly and for generating a acceleration signal representative of an acceleration experienced by the head assembly. The method includes passing a tape medium between a take-up reel and a supply reel such that a tension in the tape medium causes the tape medium to apply a pressure onto a head element, and using a pressure sensor to detect a pressure applied by the head element onto the pressure sensor.Type: GrantFiled: September 12, 2003Date of Patent: March 21, 2006Assignee: Quantum CorporationInventor: Brian Egan

Publication number: 20020148138Abstract: A shoe or boot cover adapted to slip over a workman's shoes to protect floors and carpets from dirt and deleterious materials carried in from outside. The cover has an elasticized upper open seam and a flat combined sole and heel portion made of non-skid neoprene or rubber. The cover body can be made of canvas, nylon, denim, or cotton. The body and sole-heel portion are attached by either adhesive or stitching. The shoe or boot cover is washable and reusable countless times, yet is uncomplicated in construction, and thus very inexpensive to manufacture.Type: ApplicationFiled: March 29, 2002Publication date: October 17, 2002Inventor: Brian A.

Patent number: 6226512Abstract: During the occurrence of an incoming call to a portable handset within an in building telephone system, a method is disclosed for providing additional information about the calling party, beyond simply their name or number, to a display on the handset. The name or number of the calling party is extracted by a central switching controller and is used as a reference in the look up of additional calling party attributes from a database located within a personal computer connected to the central switching controller. If the name or number of the calling party is found in the database, a data session is started between the called handset and the database. Following the starting of the data session, the first attribute in the database for the calling party is written to the display of the called handset and additional attributes are offered to the user.Type: GrantFiled: June 4, 1998Date of Patent: May 1, 2001Assignee: Nortel Networks LimitedInventors: Robert Paul Macaulay, Brian Egan

Patent number: 6188886Abstract: During the occurrence of an incoming voice call to a portable telephone handset within an in building telephone system, a method is disclosed for offering the voice call while the called handset is in a data session with an application. In such a case, the data session is interrupted and the handset display and softkey information is saved to memory. The name or number of the calling party is then written to the display of the called handset while the incoming call is offered to the user. A call acceptance signal from the called handset results in the establishing of a voice communication connection between the handset and the calling party. Independent of whether the incoming call is accepted or rejected by the user of the called handset, the saved display and softkey information is restored to the called handset and the data session is resumed between the portable handset and the application once the selection is made.Type: GrantFiled: June 4, 1998Date of Patent: February 13, 2001Assignee: Nortel Networks LimitedInventors: Robert Paul Macaulay, Brian Egan
