Title: Rail vehicle with an articulated joint
Inventor: HACHMANN ULRICH
IPC: B61G5/02
Filed: 1998-03-18
Abstract: The invention relates to a rail vehicle which has two wagon bodies (1, 2) coupled via a single axle articulated joint (8), said wagon bodies each placed elastically on a double axle bogie positioned approximately in the longitudinal central area. Control elements are provided to detect the angle of rotation between the wagon bodies (1, 2) and their corresponding bogies (4), and the angle of articulation at the articulated joint (8) as well as controllable actuators for influencing the angle of articulation depending on the control elements. The angle of articulation is regulated to a control value, said control value being the sum of the current actual angle of articulation measured (K-ist) and the bending angle (A1 and A2), in order to be able to minimise the clearance required whilst the railway vehicle is travelling dynamically.

Title: Method for coding an audio signal
Inventor: HERRE JUERGEN
IPC: H04B1/66
Filed: 1998-03-13
Abstract: A method for coding or decoding an audio signal combines the advantages of TNS processing and noise substitution. A time-discrete audio signal is initially transformed to the frequency domain in order to obtain spectral values of the temporal audio signal. Subsequently, a prediction of the spectral values in relation to frequency is carried out in order to obtain spectral residual values. Within the spectral residual values, areas are detected encompassing spectral residual values with noise properties. The spectral residual values in the noise areas are noise-substituted, whereupon information concerning the noise areas and noise substitution is incorporated into side information pertaining to a coded audio signal. Thus, considerable bit savings in case of transient signals can be achieved.
Patent CA-2286307-A1 (CA)
Inventor: HOOYKAAS PAUL JAN JACOB
IPC: C12N15/80
Filed: 1998-03-24
Abstract: The invention relates to Agrobacterium mediated transformation of moulds comprising species of the fungal sub-divisions Ascomycotina, Basidiomycotina, Deuteromycotina, Mastigomycotina, and Zygomycotina. Examples demonstrate the transformation of Aspergillus awamori (both protoplasts and conidia), Aspergillus nidulans, Aspergillus niger, Colletovtrichum gloeosporioides, Fusarium solani pisi, Neurospora Crassa, Trichoderma reesei, Pleurotus ostreatus and Agaricus bisporus (all conidia), and Fusarium graminearum (both conidia and rehydrated freeze dried ATCC material). Especially for Aspergillus awamori the transformation frequency is much higher than with conventional mould transformation techniques. It has further been found that not only one expressable gene can be introduced into these moulds, but even multiple copies of such gene, which, moreover, can be targeted e.g. in the chromosomal pyrG  locus, as exemplified for A. awamori. These multiple copies can be of a gene encoding a desired, homologous or heterologous, protein.
Patent CA-2286532-A1 (CA)
Inventor: BORG CHARLES
IPC: G06F15/02
Filed: 1999-10-14
Abstract: A portable electronic device for recording information is disclosed. The device has a display which displays preset category screens in a predetermined order. Each preset screen represents a category of information to be recorded. The device has one switch, which when activated, causes the display to display the next category screen in the predetermined order.      The device also has a second switch which, when activated, causes the device to select the category corresponding to the category screen being displayed by the display device to input information. Two additional switches are provided for inputting the value of the category selected. Activation of the switches causes the value being displayed on the display to increase or decrease by a predetermined amount until the value being displayed corresponds to the value to be inputted. Once the value being displayed corresponds to the value to be inputted, one of the first set of input switches is activated to input the value and return the device to its original state.      The device in its original state is generally a wrist watch displaying the time and date. The device can also send several alarm signals to the user indicating that it is time to input one or more categories of information into the device for recordal.

Filed: 2000-05-29
Abstract: A CDMA wireless communication system for communicating with wireless terminals. The system comprises a channel estimator for determining characteristics of the wireless channels of the wireless terminals. The channel characteristics are used by a code optimizer to assign spreading codes to the wireless terminals.  In one embodiment, the code optimizer utilizes an iterative code optimization algorithm and maintains a processing set of wireless terminals. The code optimizer chooses target wireless terminals and performs a random code search in order to find an improved code for the target wireless terminal. The improved code found in the random code search is further improved by performing a gradient search of codes in the signal space in the vicinity of the improved code and by performing a gradient search of transmission delays. The improved codes are transmitted to the wireless terminals for use in reverse link communication.
