Title: Shock absorber
Inventor: BELL STEPHEN H
IPC: F16F9/32
Filed: 1993-02-12
Granted: 1997-03-18
Abstract: An improved piston compression valve mechanism for a shock absorber includes a seal carrier member carried by the shock absorber piston and having a radially extending flange portion and a downwardly extending  cylindrical  portion,  an  o-ring  seal mounted between upper and lower radially extending arms  on the  flange portion,  and a  coil  spring mounted on the piston above the seal carrier member. The lower arm of the flange portion has an inner downwardly  facing  surface  adapted  to  engage  an upwardly facing valve seat on the piston, and the upper arm of the flange portion has an upwardly facing surface in force transmitting contact with the lower end of the coil spring.  The cylindrical portion of the seal carrier member is provided with a  plurality  of  flow  openings  spaced  about  its circumference and along its axial length which are normally in a closed position against the piston. During a compressive movement of the shock absorber, fluid  in  the  compression  chamber  of  the  shock absorber  increases  its  pressure  on  the  outer downwardly facing surface of the flange portion, causing the seal carrier member to slide upwardly on the piston initially without spring resistance and then against increasing spring resistance, thereby gradually exposing the flow openings so as to permit fluid to move from the compression chamber to the rebound chamber in the shock absorber.  The improved compression valve mechanism is dependent on fluid pressure, rather than fluid viscosity, resulting in a valve mechanism that reduces shock absorber fade at high fluid temperatures.

Granted: 1996-01-02
Abstract: A high speed anti-friction bearing includes an internal  impeller mechanism to provide  improved high  speed  lubrication  for  the  anti-friction elements.   At high bearing speeds the  impeller mechanism scoops liquid lubricant from a liquid annulus centrifugally generated on the outer wall of the bearing.   The  scooped liquid  is hurled inwardly onto the anti-friction elements as a fine mist.  The bearing lubrication process is achieved with minimum heat generation and minimum energy loss insofar as the anti-friction elements do not plow through large masses of lubricant.

Title: Method for preventing inadvertent betrayal by a trustee of escrowed digital secrets
Inventor: FISCHER ADDISON M
IPC: G06F1/00
Filed: 1994-04-06
Granted: 2000-02-22
Abstract: The invention employs a voluntary identification/definition phase performed, for example, shortly after a computer is purchased, and a secret information retrieval phase. In the definition phase, the true owner/customer defines an escrow record which provides self-identification data together with encrypted password data. The present invention prompts a user to voluntarily escrow password or other secret information for later retrieval by entering a series of information uniquely describing himself or herself. The identification indicia is combined with the secret information (such as the user's encryption password) and is then encrypted under the control of the trustee's public key. The combined information may be encrypted, for example, under a random symmetric key (such as DES) which is then encrypted under the trustee's public key. After unique identification data has been entered, the user is asked to select a password to protect the system. Thereafter, all the personal identifying data, together with the password, is encrypted with the trustee's public key and is stored, for example, in the user's computer as an escrow security record. The password is then used to encrypt all data on the user's disk. If at some point in time in the future, the user forgets the password, the retrieval phase of the applicant's invention is performed. Under such circumstances, the user contacts the trustees, e.g., the vendor or manufacturer. The trustee utilizes documentary evidence presented by the alleged legitimate user and determines whether such evidence matches with the previously encrypted escrow information stored in the escrow record created by the user. If they agree, then the trustee has confidence that the true owner is making the request, and that revealing the secret key will not betray the owner's interest.

Title: Method and apparatus for producing a composite second image in the spatial context of a first image
Inventor: STONE MAUREEN C
IPC: G06T11/00
Filed: 1994-05-30
Granted: 1999-04-20
Abstract: A method is disclosed for operating a processor-controlled machine to produce a composite view of an original, or first, image by combining the functions of multiple viewing operations and using the model data structure from which the first image was produced (called the "FIMDS".) A first viewing operation region (1VOR) in a first viewing position in the display area of the display device has displayed in the 1VOR a second image produced according to a first viewing operation (VO1), associated with the 1VOR, that maps the FIMDS to image definition data defining the second image. Request signal data is received from a signal source to present a second viewing operation region (2VOR) in the display area coextensive with at least a portion of the 1VOR, forming a composite viewing operation region in the overlapping region. The 2VOR has a second viewing operation (VO2) associated with it for mapping an input model data structure, typically but not necessarily the FIMDS, to image definition data defining a second image for display in the 2VOR (2VOR-SI), providing an alternate view of the FIMDS that is different from that provided by the VO1 associated with the 1VOR. In response to the request signal data, a composite viewing operation, composed from the functions of the VO1 and the VO2, maps the FIMDS to image definition data defining a composite image for display in the composite viewing operation region substantially at the same time as the first image is being displayed in the display area. This gives the perception to the machine user of applying composed viewing operations to information presented in the original image.
