Patent CA-2375127-C (CA)
Title: Device and method for preparing plastic material, in particular thermoplastic material
Inventor: BACHER HELMUT
IPC: B29C48/285
Filed: 2000-05-24
Granted: 2005-04-05
Abstract: The invention relates to a device for preparing plastic material, in particular, thermoplastic material. Said device comprises a receptacle (1) f or accommodating the material, in which revolving tools (21) that are transport ed on a support disc (9) and that act upon the material are provided. The tools revolve around the vertical axis (8) of the receptacle (1). The drive of the support disc (9) is operated by a shaft (4) which passes through the base (3 ) of the receptacle (1) and is driven by a motor (5). The material is removed from the receptacle (1) through a discharge opening (15), onto which the housing (16) of a worm (17) is attached. The discharge opening (15) is provided in the same receptacle (1) and lies below the circular path of the tools (21) and below the support disc (9). Additional tools (12) which are displaced are arranged in said receptacle (1) below the support disc (9) whi ch convey the material into the discharge opening (15). The treated plastic material thus remains in the receptacle (1) for a long period of time, allowing the construction length of the worm (17) to be reduced and the driv e energy of the worm to be saved. The invention also relates to a method for preparing plastic material of this type, in which the material is continuous ly treated by two sets of tools, arranged one on top of the other, in two sequential stages. In the first stage, performed by the upper set of tools, the material is pre-crushed and/or pre-heated and/or pre-dried and/or pre- mixed. In the second stage, performed by the lower set of tools, the materia l is treated in the same way, but in a less intensive manner than during the first stage. The treated material is then fed by the tools of the second sta ge to a worm which discharges the material from the receptacle.

Title: Radio based proximity token with multiple antennas
Inventor: XYDIS THOMAS
IPC: H04W84/12
Filed: 2000-11-30
Granted: 2010-04-27
Abstract: A method of detecting a signal (10, 10') between a token (12) and an electronic device (14) for authorizing a user (16) to access the electronic device (14). The method comprises the steps of emitting a signal (10, 10') containing data, detecting the signal (10, 10') with a plurality of antennas (18, 18'), and measuring the strength of the signal (10, 10') detected at each of the antennas (18, 18'). If the maximum signal strength detected by any of the antennas (18, 18') is above an operational threshold, the electronic device (14) will be enabled. If the signal (10, 10') is above the operational threshold, the signal (10, 10') is compared to a user code database for authorizing the user (16) to access the electronic device (14). The operational threshold may be lowered to account for any signal variances that may occur after the user (16) has been authorized to access or when accessing the electronic device (14).

Abstract: An apparatus for detecting landmines is based on obtaining thermal signatures with an infrared camera (12) of a soil surface where a buried landmine might exist. An optical band filter (14) is positioned in front of the camera, which filter (14) is transmissive to selected band wavelengths but strongly attenuates radiation outside of the selected bands. The filter (14) is one selected to pass radiation in an optical band in which solar radiation is absent or highly attenuated at the earth's surface due to absorption by the molecular aerosol or particulate constitute of the atmosphere. This ensures that most of the solar radiation scattered from the ground surface is blocked from reaching the infrared camera's sensor, thereby eliminating clutter in infrared images of the soil surface.

Abstract: A method of editing a digital image having associated embedded data, such as printing hints, includes embedding a first watermark in the original image before the image is edited. The first watermarking scheme associates first watermark information with each pixel and is used to detect which pixels have been edited. A second watermark may be embedded in the original image according to a second watermarking scheme which associates second watermark information with non-overlapping groups of pixels in the original image. The second watermark information may be used to synchronize the first watermark information and to detect editing information which does not change pixel values. After editing, only those edited portions of the image need have their embedded data reapplied.
