Abstract: A chassis (10) for a vehicle is disclosed which combines rigidity, speed of manufacture, and an small environmental footprint. Such a chassis comprises a framework of interconnected tubular sections (12,14,16,18, 20, 22, 28) and at least one sheet (50) bonded to the framework. Laser cutting, CNC bending, and computer-controlled welding mean that the required production time can be kept to 120 seconds and the rigidity of the structure as a whole is sufficient. Such a chassis also has an exceptionally low carbon footprint. The sheet can be metallic, such as Aluminium or Aluminium honeycomb, or it can be a composite material such as one comprising a paper-based core and a fibre-reinforced plastics coating. The sheet can be non-flat, and is preferably a concave geometry such as a tub. It can be composed of a plurality of sections, ideally joined by a method allowing a positional tolerance so that any tolerance in the construction of the framework can be accommodated. A corresponding method of manufacturing a chassis is also disclosed.

Filed: 2011-01-20
Abstract: A wellbore obstruction-clearing tool connected to the bottom of a tubing string, such as casing, utilizes a sleeve which is axially and rotationally moveable in response to axial reciprocation of a tubing string to engage and clear obstructions in the wellbore. Fluid is discharged through the casing and the tool to engage the obstructions and to convey debris through the annulus to surface. Thus, the obstructions are cleared from the wellbore, permitting the casing to be advanced, without the need to rotate the casing.

Title: Life safety device with extended shelf life
Inventor: BUCHHOLZ MATTHEW J
IPC: H01M10/44
Filed: 2009-10-16
Abstract: A life safety device in-cludes a battery assembly with a rechargeable battery. Extended shelf life is achieved by annually initiating an over-discharge protection mode in which a battery protection circuit pre-vents current flow from the battery.  The life safety device remains in the over-discharge protection mode until the device is connected to a charging power source at the time of installa-tion.

Inventor: BROWN DANIEL R L
IPC: H04L9/30
Filed: 2009-12-16
Abstract: The generation of a shared secret key K in the implementation of a key agreement protocol, for example MQV, may be optimized for accelerated computation by selecting the ephemeral public key and the long-term public key of a correspondent to be identical. One correspondent determines whether the pair of public keys of the other correspondent are identical. If it is, a simplified representation of the shared key K is used which reduces the number of scalar multiplication operations for an additive group or exponentiation operations for a multiplicative group.  Further optimisation may be obtained by performing simultaneous scalar multiplication or simultaneous exponentiation in the computation of K.
