Title: Fuel cells, electrodes, and method of manufacture
Inventor: HUGH LIAM SUTHERLAND
IPC: H01M8/083
Filed: 2014-09-02
Abstract: An electrode (10) comprises a metal sheet (11) defining multiple through-holes (14), and a fluid-permeable layer (16) comprising fibrous and/or particulate electrically- conductive material and a polymer binder, which is to be bonded to a front surface of the metal sheet (11). In making the electrode (10), the front surface is subjected to an etching process to form multiple depressions (21) or blind recesses that do not extend through the metal sheet (11); placing the fluid-permeable layer onto the front surface to form an assembly; and subjecting the assembly to compression such that the fluid-permeable layer (16) bonds to the metal sheet (11) and protrudes into the through-holes (14) and into the depressions (21). No polymeric bonding layer on the metal surface is required, and the depressions (21) lead to satisfactory adhesion between the metal sheet (11) and the fluid permeable layer (16), and improved electrical properties of a fuel cell (25) that incorporates the electrode (10).

Title: Steering column with decoupling J-slider
Inventor: Jeff steven vinton
IPC: B62D1/19
Filed: 2016-11-07
Abstract: An energy absorbing steering column with a J-shaped (or hook-shaped) lower intermediate shaft that is coupled to an upper intermediate shaft. The J-shaped lower shaft 302 includes a curved slider portion that fits within a bent portion of the upper shaft 304 such that even when the rigid connection, i.e. shear pin coupling 308, 308a, 308b, between the J-shaped lower shaft and the upper shaft is broken, the slider portion of the J-shaped lower shaft remains in contact with the upper shaft. Such a configuration dissipates the force applied to the steering column and enables the driver to maintain control of the vehicle through the steering wheel following a load event, such as a frontal impact (Figure 4B). A first predetermined level of force may cause the J-shaped lower shaft to break its rigid connection with the upper shaft but maintain a geometric contact with the upper shaft (Figure 4B). A second predetermined level of force may cause the J-shaped lower shaft to break its rigid connection, i.e. break the shear pin, and de-couple from the upper shaft (Figure 3B, 4B) so that the upper shaft absorbs the energy and avoids transmitting a rearward force back to the driver.

Title: Methods and systems of securely transferring data
Inventor: JOHN PETER MICHAEL
IPC: H04L29/06
Filed: 2018-11-07
Abstract: Transfer of key material between a master keying material source (MKMS) 20 and a slave dongle 12a-n by connecting each dongle to a data transfer system 30. A dongle’s public key is transferred to the MKMS and the MKMS encrypts the master key with it. The encrypted master key is then sent to the dongle which decrypts it with its private key and stores it. Each dongle obtains the same master key using this process and the dongles may then securely communicate with one another. Alternatively, the MKMS may share its public key with the dongle and both use the same algorithm to create a session key from their public keys, the session key being used to encrypt the master key. The MKMS may be held by a software program or a firmware program on a dedicated chip and the master key may be symmetric encryption key generated by FIPS random number generator. The dongle may require user authentication by keypad entry or biometric sensor to be unlocked. The dongle public key may be scrambled before transmission and unscrambled at the MKMS using a predetermined scrambling algorithm. The data transfer system may be a dedicated device like a USB hub.
