Title: Push-push latch mechanism for retaining a component in a device
Inventor: DELUGA RONALD E
IPC: E05B53/00
Filed: 2005-08-26
Abstract: A latch mechanism which retains a component (12, Fig. 1A) in a device (10, Fig. 1A) comprises a latch feature 31 which is connected to the component and has a tang 35 and a cavity 32, and a latch module 21 which is connected to the device and has a first pin 42 and a second pin 41. When the component is inserted into the device, the tang causes movement of the first pin towards the second pin, which in turn causes the second pin to move from a position within the latch module (Fig. 5) to a position within the cavity. The first pin then returns to its original position under a spring bias, and the component is retained in place (Fig. 7). The latch mechanism may be formed as a push-push latch mechanism, wherein subsequent movement of the first pin towards the second pin, by pushing the component in the insertion direction, causes the second pin to be returned to its position within the latch module, the component being ejected under the spring bias of the first pin (Fig. 9). In an alternative embodiment, the latch feature is connected to the device, and the latch module is connected to the component.

Title: Turbocharging in a variable displacement i.c. engine, ie having cylinders selectively disabled
Inventor: LAMB BILL DAVID
IPC: F02D17/02
Filed: 2005-10-03
Abstract: A variable displacement i.e. engine, ie with cylinder(s) that can be selectively deactivated, has two turbochargers 20, 22 the turbines of which are connected to all the engine cylinders, eg by parallel branches 34, 36. The turbochargers may be of different sizes. Valving controlled according to the number of deactivated cylinders is provided in the exhaust system for selectively directing the exhaust gases to drive one, the other or both turbines. The valving may comprise a butterfly valve 18 in branch 36 and may also be controlled in dependence upon throttle position, manifold pressure, rate of change of throttle position, vehicle speed, fuel consumption or engine speed. In fig. 1, two cylinders 14 are deactivated and valve 18 is closed so that turbocharger 20 generates sufficient compressed air for the active cylinders and turbocharger 22 does not compress much air. When only one cylinder is deactivated (fig.2), valve 18 is partially open and both turbochargers operate. When all cylinders are enabled (fig.3), valve 18 is fully open and most of the exhaust flows through the larger turbocharger 22.

Title: System and method for power ratio determination with common mode suppression through electric field differencing.
Inventor: ABREU RENE
IPC: G01N21/35
Filed: 2006-03-30
Abstract: A system for processing signals includes a receiver assembly 10 for receiving a signal. The signal has a sample component with a sample electric field and a sample polarization, and has a reference component with a reference electric field and a reference polarization. The receiver assembly includes an analyzer 26 for polarimetrically processing the signal, including differencing the signal to generate a difference electric field proportional to the difference of the sample and reference electric fields. By polarimetrically differencing the signal, the analyzer reduces the magnitude of the common-mode signal at the difference signal receiver. The receiver assembly includes an electric-field detector for measuring the difference electric field such that the reduction in common-mode amplitude decreases the noise equivalent power of the electric-field detector. One advantage of the present invention, then, is the reduction of noise equivalent power of the electric-field detector when measuring small variations in large electric fields.

Title: Terahertz radiation sensor and imaging system
Inventor: CRAWLEY DAVID ALEXANDER
IPC: G01N21/45
Filed: 2004-01-19
Abstract: Apparatus and methods for sensing terahertz radiation, in particular over an area, and to terahertz radiation imaging systems. A probe beam 202 is inserted into a polarizing beam splitter 214 and passes to an electro-optic crystal detector 206. A terahertz pulse 204 induces a change in the birefringence of the crystal which induces changes in the polarization of the optical pulse in the location where the THz field is present. The probe beam is reflected from a front surface of the EOS crystal and passes back through the beam splitter 214 to a photosensitive imaging device 220 such as a CMOS or CCD chip. The detector 206 is not in a terahertz radiation image plane i.e. the sensor is configured such that terahertz radiation falling on said detector is substantially unfocussed. This can reduce cost and increase ruggedness and compactness of the sensor, as well as facilitating near field imaging in potentially hostile environments with high image resolution.
