Patent CA-2146406-A1 (CA)
Title: Panoramic fish-eye imaging system
Inventor: POWELL IAN
IPC: G02B13/08
Filed: 1995-04-05
Abstract: A new panoramic/fish-eye imaging system for projecting a 360 degree cylindrical field of view onto a two-dimensional annular format is described. It is rotationally symmetrical and comprises two groups of optics, each having very distinct functions. The front group of optics is basically a catoptric system employing a concave and convex mirror for converting the extreme field angles to a more manageable intermediate image. The rear group acts as a relay lens to transfer the intermediate image formed by the front group to some accessible location downstream. For improved overall performance, aberration, compensation of the front group is included in the design of the relay optics. A further refinement to the design is the inclusion of an additional optical element in the form of refracting negative shell located in front of the entire arrangement. This increases the effective field of view and is useful when fields of view exceeding 180 degrees are required.

Title: Fastening Device for a Tool or Workpiece
Inventor: SCHANZ MANFRED
IPC: B23Q16/08
Filed: 1995-08-10
Abstract: The fastening of two parts (1 and 3) to one another, e.g. of a tool or workpiece, on a holder provides that the two parts (1 and 3) to be fastened together have adjoining fitting areas (4 and 5) when in use and are braced against one another by fastening means, e.g. a single fixing screw (2), extending diagonally or at right angles to the contact plane of these fitting areas (4 and 5). In this cask in addition to the fitting areas (4 and 5) fixing the reciprocal axial position in Z direction, fitting projections (9) are provided on the one part and fitting recesses (10) on the other part which prevent the parts (1 and 3) connected and braced with one another from shifting diagonally to the fastening means within the contact plane of fitting areas (4 and 5) and which center the two parts (1 and 3) diagonally to this contact plane in X and Y direction so as to fit accurately. The fitting projections (9) are thereby on an area (il) which can deviate elastically, or is flexible, in axial direction against a deformation force which can be applied by the screw (2), of the part (1 or 3) on which they are located, so that the fitting projections (9) engage so as to fit accurately in the fitting recesses (10) before the fitting areas (4 and 5) come in contact. By tightening the fastening means more, fitting areas (4 and 5) then also come into reciprocal contact without the need for an additional part for adjusting or centering in X and Y direction.

Patent CA-2161540-A1 (CA)
Inventor: KARAALI ORHAN
IPC: G10L13/00
Filed: 1995-03-21
Abstract: Text may be converted to audible signals, such as speech, by first training a neural network using recorded audio messages (204). To begin the training, the recorded audio messages are converted into a series of audio frames (205) having a fixed duration (213). Then, each audio frame is assigned a phonetic representation (203) and a target acoustic representation, where the phonetic representation (203) is a binary word that represents the phone and articulation characteristics of the audio frame, while the target acoustic representation is a vector of audio information such as pitch and energy. After training, the neural network is used in conversion of text into speech. First, text that is to be converted is translated to a series of phonetic frames of the same form as the phonetic representations (203) and having the fixed duration (213). Then the neural network produces acoustic representations in response to context descriptions (207) that include some of the phonetic frames. The acoustic representations are then converted into a speech wave form by a synthesizer.
