Patent number: 6474733Abstract: A headrest in a vehicle seat includes an inflatable protective cushion in which the contact surface area is increased and caused to approach the head without needing to provide burst seams in the upholstery or in the cover or to make use of an elastic covering material. The protective cushion is arranged between the headrest frame member and the upholstery. The cover or the upholstery is joined at its outer circumference by jointing means to the headrest frame member. The jointing means maintain the cover, or the upholstery, tensioned in the non-activated condition of the protective cushion and permit a limited displacement of the outer circumference of the cover, or upholstery, from the headrest frame member in the activated condition of the protective cushion. The upholstery may thus be brought by the protective cushion nearer to the head and the contact surface area may be enlarged without destroying the cover or upholstery.Type: GrantFiled: April 20, 2000Date of Patent: November 5, 2002Assignee: TRW Occupant Restraint Systems GmbH & Co. KGInventors: Alexander Heilig, Lothar Zink

Patent number: 6475230Abstract: An improved method and apparatus is provided to secure a suture relative to body tissue. When a predetermined minimum force is being transmitted between a suture retainer and the body tissue, the suture is gripped with the suture retainer by plastically deforming material of the suture retainer. One or more bends may be formed in suture by the suture retainer to increase the holding action between the suture retainer and the suture. The bends in the suture may be formed by wrapping the suture around a portion of the suture retainer. During movement of the suture retainer toward the body tissue, the bends may be moved along the suture. One or more bends may be formed in the suture by bending a tubular member through which the suture extends. The tubular member may be maintained in a bent condition by a C-shaped holder member. Alternatively, the tubular member may be maintained in a bent condition by members which are latched together.Type: GrantFiled: March 10, 2000Date of Patent: November 5, 2002Inventors: Peter M.

Patent number: 6473133Abstract: A transmission system (14) broadcasts a signal. Within the system (14), a power amplifier (20) causes non-linear distortion. A pre-amp component, such as a band-pass filter (32), causes linear distortion. A high power filter (38) is located downstream of the power amplifier (20) and causes linear distortion. A linear equalizer (42) compensates for the distortion caused by the high power filter (38). A non-linear corrector (44) compensates for the distortion caused by the power amplifier (20), and is located downstream of the linear equalizer (42). A linear equalizer (46) compensates for the distortion caused by the pre-amp components (e.g., 32). The compensating components (42-46) are located upstream of the distorting, pre-amp component (e.g., 32). A interpolation component (22) is located between the three compensating components (42-46) and the distortion causing components (20, 32, and 38) to increase a rate of the signal, such that the compensation occurs at a lower rate of the signal.Type: GrantFiled: May 14, 1999Date of Patent: October 29, 2002Assignee: Harris CorporationInventors: Edwin Ray Twitchell, Wayne D.

Patent number: 6471851Abstract: Humectants are applied to cathodic protection systems which utilize thermally-sprayed zinc or zinc alloy anodes applied to the surface of reinforced concrete structures. The humectants are deliquescent or hygroscopic organic or inorganic salts, hydrophilic polymers or colloids, or organic liquid desiccants. The humectants are positioned at or near the interface between the anodes and the concrete and increase the moisture content at the interface. This increases the ability of the anode to deliver cathodic protection current to steel embedded in the concrete. The humectants may be applied to the concrete surface prior to application of the anode, or may be applied subsequent to installation of the anode.Type: GrantFiled: April 17, 1997Date of Patent: October 29, 2002Inventor: Jack E.

Patent number: 6468293Abstract: Improved method is provided to secure a suture relative to body tissue. A suture retainer is moved along first and second sections of a suture toward the body tissue. When a predetermined minimum force is being transmitted between the suture retainer and the body tissue, the first and second sections of the suture are gripped with the suture retainer by plastically deforming material of the suture retainer. The material of the suture retainer cold flows under the influence of force applied against the surface areas on the suture retainer. One or more bends are formed in each of the sections of the suture to increase the holding action between the suture retainer and the sections of the suture. The bends may be formed by wrapping a turn of the suture around a portion of the suture retainer. During movement of the suture retainer toward the body tissue, the bends are moved along the first and second sections of the suture.Type: GrantFiled: May 7, 2001Date of Patent: October 22, 2002Inventors: Peter M.
