Patent number: 6244638Abstract: An improved energy management device comprises a substrate body and at least one permeable insert sheet disposed in the substrate body. The shape and orientation of the sheet may be varied. In the various embodiments, the insert sheet has a wall substantially transverse to the energy absorbing surface of the energy management device. The substrate body and the at least one energy absorbing insert sheet are engaged with respect to one another. This may be achieved by having at least a portion of the substrate body disposed in the permeable portion of the insert sheet thereby “locking” in place the insert sheet. It has been discovered that such a combination of a substrate body and an insert sheet surprisingly and unexpected results in improved energy management properties when compared to the independent energy management properties of the substrate body and the insert sheet. The energy management device is useful, for example, in the construction of a vehicular bumper.Type: GrantFiled: January 26, 1998Date of Patent: June 12, 2001Assignee: Woodbridge Foam CorporationInventors: Edward T.

Patent number: 6244675Abstract: A fail-safe system 2, in which the position of an actuating device 4 is measured by three sensors 8, 10 and 12 that operate independently of one another. The sensor 8 is directly supplied with energy by a first energy source 20, and the sensor 12 is directly supplied with energy by the second energy source 22 of the system 2. The sensor 10 is supplied with energy by the first energy source 20 or by the second energy source 22 via a diode circuit 14, 16 such that, if one of the energy sources 20 or 22 fails, two of the three sensors 8, 10 and 12 are still supplied with energy. A majority decision can be carried out in the microprocessors 32 or 34 if the signal of one sensor is lacking, wherein it can also be determined which of the energy sources 20 or 22 has failed.Type: GrantFiled: September 8, 1999Date of Patent: June 12, 2001Assignee: Continental AktiengesellschaftInventors: Holger Behrends, Christof Maron, Thomas Dieckmann

Patent number: 6244676Abstract: A negative pressure control apparatus for a brake booster for controlling a negative pressure in a negative pressure chamber of the brake booster is provided. The apparatus is applied to a system having a booster charge mechanism for generating a fluid pressure by using the negative pressure in the negative pressure chamber and a fluid pressure control mechanism for controlling a brake fluid pressure by using the fluid pressure generated by the booster charge mechanism as a fluid pressure source. The apparatus includes a negative pressure controller for controlling the negative pressure in the negative pressure chamber to be at least a predetermined target negative pressure. A temperature detector detects information relating to a temperature of brake fluid. A target negative pressure setting part sets the predetermined negative pressure based on the temperature of the brake fluid.Type: GrantFiled: April 23, 1999Date of Patent: June 12, 2001Assignee: Toyota Jidosha Kabushiki KaishaInventors: Ryochi Watanabe, Yoshihisa Yamada, Hiroaki Endo

Array and method for standardizing cartridge location within storage cells of a data storage library
Patent number: 6244677Abstract: An array and method for standardizing the location of cartridges within a data storage library are provided. The array includes at least one storage cell for receiving at least a portion of a cartridge, where the storage cell includes a first side wall and a second side wall substantially parallel to the first side wall, and the first side wall has a resilient member that is mountable thereon. Upon insertion of a cartridge into the storage cell, the resilient member is operable to engage a first side face of the cartridge and dispose a second side face of the cartridge in contact with the second side wall, defining a reference width position. Depending on the dimensions of the cartridge, either a back abutment or at least one stop extending generally perpendicularly from the first or second side wall preferably engages a back face of the cartridge to limit its depth within the storage cell, such that a reference depth position forward from the storage cell is established.Type: GrantFiled: July 28, 1999Date of Patent: June 12, 2001Assignee: Storage Technology CorporationInventors: David R. Millhiser, Daniel J. Plutt -
Patent number: 6244678Abstract: An integrated anti-rebound mechanism with stop feature for a rail assembly. Two stop/anti-rebound pieces are individually attached at the forward end of a first rail and a second rail of the rail assembly. The stop/anti-rebound pieces engage one another when the first and second rails are in a closed position to prevent the first and second rails from moving beyond a closed position from an extended position. The stop/anti-rebound pieces also cooperate to resist movement of the first and second rails from a closed position. A third rail may be included in the rail assembly including a stop mechanism and an anti-rebound mechanism. The stop and anti-rebound mechanisms cooperate with on of the stop/anti-rebound pieces of the other rail to prevent the third rail from moving beyond a closed position, and to resist movement of the third rail from a closed position in relation to the other rail.Type: GrantFiled: September 9, 1999Date of Patent: June 12, 2001Assignee: Thomas Regout USA, Inc.Inventors: Alex Dopp, Herman T. Smeets, Alan R. Wright

Patent number: 6244680Abstract: Detecting a quantity of a product remaining in a reservoir subjected, during use of the product, to a driving movement. The reservoir is driven in accordance with reference signals representing target movements. The reference signals including at least one test reference signal. The position of the reservoir in response to the test reference signal is detected. The quantity of product remaining in the reservoir is determinable from the detected position. Alternatively, a change in temperature caused by moving the reservoir in response to the test reference signal is detected, and the quantity of product remaining in the reservoir is determinable from the change in temperature.Type: GrantFiled: October 25, 1996Date of Patent: June 12, 2001Assignee: Canon Kabushiki KaishaInventors: Christophe Truffaut, Pascal Coudray, Marie-Hélène Froger, Alexandre Dodge

Patent number: 6244681Abstract: The purpose is to provide a high quality halftone recording with a reduced grainy feeling without lowering the true resolving power. Provided is an apparatus for making a halftone recording by employing three or more types of color materials, each of which has at least one grade of concentration, wherein each type of the color materials having the lowest concentration provides, when recording on a recording medium having a first lightness, a recorded region having its own lightness, and wherein a difference between the first lightness and the lightness of the recorded region is not more than 35, the lightness being measured according to the definition of CIE 1976 psychological measurement lightness using a standard illuminating light D65 as a light source.Type: GrantFiled: April 22, 1997Date of Patent: June 12, 2001Assignee: Canon Kabushiki KaishaInventors: Kentaro Yano, Naoji Otsuka, Kiichiro Takahashi, Hitoshi Nishikori, Osamu Iwasaki, Daigoro Kanematsu, Hidehiko Kanda

Patent number: 6244684Abstract: An ink jet printer of the present invention includes a recovering device for repeating, at the time of recovery from defective ink ejection, the suction of ink a plurality of times while varying a suction pressure acting on the ink. This successfully reduces the amount of bubbles and reduces the number of times of suction to thereby obviate the wasteful consumption of ink at the time of recovery. A printing method practicable with the ink jet printer and a storage medium storing the printing method are also disclosed.Type: GrantFiled: March 17, 1999Date of Patent: June 12, 2001Assignee: NEC CorporationInventors: Kuniaki Kokai, Koichi Tanaka
