Title: Fabrication of integrated modulated waveguide structures by self-alignment process
Inventor: VONSOVICI ADRIAN PETRU
IPC: G02F1/025
Filed: 2001-03-27
Abstract: An self-aligning process for fabricating integrated modulated waveguide structures involves steps of laying a resist mask (116) on a vertical feature (112) (e.g a ribbed waveguide) of a partially formed structure, and then forming further features (118) (e.g. recesses) based on this mask. This process may be performed by forming ribbed waveguide (112) using mask (110), then adjusting the extent of the mask to form fillets or lobes (116) prior to forming recesses (118). The process may also be used to form waveguide (10) and modulator (20,22,24) by defining the higher feature of the waveguide and modulator, and then locating a resist mask relative to this feature, and defining the remaining features of the structure. The fillets (116) may be formed by anisotropic etching of resist mask layer (115, Fig. 5) . As the fillets (116) are located relative to the ridge waveguide structure (112), the recesses (118) will be accurately located relative to the ridge waveguide (112), thus avoiding the need for a highly precise alignment step to form recesses (118) following the formation of waveguide (112). The separation between the ribbed waveguide (112) and the trench (118) can be defined to an accuracy of 50 nm, so variations are under 20% for separations in the range of 1 žm to 2 žm.

Title: Fabricating a three-dimensional article from powder
Inventor: DARRAH JAMES F
IPC: B29C67/00
Filed: 2001-07-31
Abstract: A computer-controlled apparatus and method for fabricating three-dimensional articles in layerwise fashion is disclosed. Upon dispensing a layer of a fusible powder, a laser 110 irradiates selected locations of that layer on a target surface 104 to fuse the powder into a cross-section of the article to be formed in that layer, such that the cross-sections fuse together into the article. The laser 110 is controlled in a raster scan fashion across the selected locations of the powder layer. The raster scan lines are defined, for each cross-section, to achieve an optimal fill scan time. The optimal fill scan time is determined, by the computer 140 estimating the fill scan time by rotating the cross-section over a plurality of rotational angles, and estimating the fill scan time for each of the rotated cross-sections for at least a sample of the fill scans necessary to form the article. The actual fill scan vectors to be used in selective laser sintering of the article are rotated, from a coordinate axis at the target plane, according to the rotation of the cross-section providing the lowest estimated fill scan time.

Patent GB-2362590-A (GB)
Title: Centrifugal evaporation apparatus
Inventor: COLE MICHAEL
IPC: B01D3/10
Filed: 1999-02-23
Abstract: Liquid samples containing solid material are evaporated under reduced pressure in a centrifugal evaporator and are heated during the evaporation process to compensate for the latent heat of evaporation. The temperature of the sample material inside the centrifugal evaporator is monitored during the evaporation process by means of a pressure sensing device located in the chamber of the centrifugal evaporator. The pressure sensing device generates an electrical pressure data signal which is proportional to the sensed pressure. The signal is sent to electronic data signal processing means which is programmed inter alia with information relating to the volatile component or components present in the samples to convert the pressure data signal to a temperature value equal to that which equates to the measured vapour pressure for the known volatile component or components present.

Title: A capacitance sensor
Inventor: MOORE SIMON
IPC: G01R27/26
Filed: 2002-02-12
Abstract: A capacitance sensor comprises an asynchronous oscillator ring 20, having a plurality of elements (figure 6, not shown). An electrode E1 is coupled, to a node between two of said elements. A sample to be identified is placed into contact with the electrode E1, and causes a change in capacitance at the electrode E1, which results in a change in the oscillation frequency of the oscillator ring 20. The change in oscillation is used to identify the sample. The sample may be for example DNA or fingerprints. The electrode E1 may have an identified sample of a material deposited on it, a change in capacitance will occur if the deposited material does not match the sample material and thus an associated change in the oscillator frequency will be detected, indicating that the sample does not match the deposited material.

Title: Symmetric key cryptosystem
Inventor: GOLIGHTLY SAMUAL JAMES
IPC: H04L9/26
Filed: 2002-03-15
Abstract: A symmetric (shared key) key encryption system which encodes message data using an algorithm, a secret key(1) and a random initial message(5) and a matching decryption system which decodes encrypted data using an algorithm and the same secret key(1). The system uses an irreversible function and a random initial message(5) to obscure the key(1) from cryptographic analysis, resulting in a system with a high level of data confidentiality at the same time as low resource utilisation and high speed operation. Confidentiality is further enhanced by the essentially linear relationship between key length and the product of resource utilisation and processing time per unit message data, allowing the system architect to select a longer key length without disproportionate increase in complexity or power consumption or decrease in speed.
