Title: Method for production of alkyl esters
Inventor: MUSKETT RAYMOND
IPC: C07C67/08
Filed: 2002-11-27
Abstract: A method for production of alkyl esters from a mixture of glycerides and free fatty acids, originating primarily from grease trap waste, is provided. The mixture is first solvated in a low boiling point alcohol and then the pH of the solution is adjusted to about 1 to 2 by addition of an acid to effect acid-catalysed alkyl esterification. The acidic solution is then treated with a concentrated alkoxide solution to raise the pH of the solution about pH12 to effect base-catalysed transesterification of glycerides contained in the mixture. The resulting solution is then treated with an acid to decrease the pH of the solution to about 2 to effect acid-catalysed esterification of residual saponified by-products. The alcohol solvent is removed by distillation or other suitable techniques and the resulting alkyl esters are separated from any remaining residues and neutralised of residual acids.

Title: Hardware security device for magnetic memory cells
Inventor: LENSSEN KARS MICHIEL H
IPC: G11C11/16
Filed: 2003-12-15
Abstract: The present invention provides a special structure of magnetic elements, e.g. MRAM elements (10, 11), as a security device (30) for IC's containing magnetic memory cells. The structure may comprise a combination of two or more associated magnetic elements (10, 11) with pre-set anti-parallel magnetization directions. By determining the polarisation directions of the magnetic elements, exposure to an external magnetic field can be detected. Inverse polarisation directions indicate a normal situation, aligned polarisation directions indicate that the MRAM-array has been exposed to an external field. In this way it can be detected whether it has been tried to erase or alter the data stored in the MRAM in an illegal way. The IC can regularly check the resistance of the security system during operation. Upon detection of a field exposure, the IC can erase all MRAM data, or can reset itself or block its functioning.

Title: A method of providing voicemails to a wireless information device
Inventor: DOULTON DANIEL MICHAEL
IPC: G10L15/00
Filed: 2004-04-22
Abstract: Voicemail is received at a voicemail server and converted to an audio file format; it is then sent or streamed over a wide area network to a voice to text transcription system comprising a network of computers. One of the networked computers plays back the voice message to an operator and the operator intelligently transcribes the actual message from the original voice message by entering the corresponding text message (actually a succinct version of the original voice message, not a verbose word-for-word conversion) into the computer to generate a transcribed text message. The transcribed text message is then sent to the wireless information device from the computer. Because human operators are used instead of machine transcription, voicemails are converted accurately, intelligently, appropriately and succinctly into text messages (SMS/MMS).

Abstract: A frame format decoder (22) and training sequence generator (24) for determining the frame format of received data which is compliant with the IEEE 802.1 lb standard for wireless local area networks, and for providing a training sequence for an adaptive equalizer (16). The received signal is first despreaded, demodulated and descrambled, so that the SYNC field is reconstructed, and then a counter 32 counts the number of consecutive bits having the same polarity or logic value until N such bits are counted (where N is an integer greater than 1). The polarity or logic value of the N counted bits enables the decoder (22) to determine whether the frame format is long or short. A training sequence, being a copy of the transmitted SYNC field eventually followed by an SFD field, is also generated for use by an adaptive equalizer (16).
