Abstract: On fabrique une bande de papier ménager en mettant en oeuvre un procédé modifié de pressage humide utilisant une presse à air complètement hermétique. Après formation initiale et déshydratation classique sous vide, la bande humide est conformée au contour de la surface d'un tissu relativement grossier pour conférer à la bande une surface structurée. En créant sur toute la bande une différence de pression d'au moins 30 pouces de mercure et un écoulement d'air traversant d'au moins 500 SCFM/in?2¿, la bande humide est déshydratée sans compression, par la presse à air, à une consistance d'environ 30 à 40 pour cent avant de passer dans un sécheur Yankee. La bande est séchée pour préserver sensiblement sa structure tridimensionnelle obtenue par séchage à air traversant. La bande ainsi produite présente une épaisseur moyenne et un pouvoir absorbant exceptionnels jamais égalés jusqu'ici pour des produits de pressage humide.

Patent CA-2329034-A1 (CA)
Inventor: BUTCHER LAWRENCE L
IPC: G06F1/00
Filed: 1999-04-20
Abstract: Authentication and session management can be used with a system architecture that partitions functionality between a human interface device (HID) and a computational service provider such as a server. An authentication manager executing on a server interacts with the HID to validate the user when the user connects to the system via the HID. A session manager executing on a server manages services running on computers providing computational services on behalf of the user. The session manager notifies each service in a session that the user is attached to the system using a given HID. A service can direct display output to the HID while the user is attached to the system. When a user detaches from the system, each of the service's executing for the user is notified via the authentication manager and the session manager. Upon notification that the user is detached from the system, a service can continue to execute while stopping its display to the HID.

Title: Network based multiple sensor device
Inventor: ECKEL DAVID P
IPC: G01K1/04
Filed: 1999-05-13
Abstract: A multifunction sensor device (10) which provides various transducer functio ns including means for performing temperature sensing, ambient light sensing, motion detection, switching functions and a means (30) to put the device in an on, off or auto mode. The device has utility in environments such as that found in offices, schools, homes, industrial plants or any other type of automated facility in which sensors are utilized for energy monitoring and control, end user convenience or HVAC control. Key elements of the invention  include overcoming the difficulty of mounting diverse sensors or tranducers within the same device or housing (14); permitting these various sensors to exist in a single package that can be mounted to a wall in a substantially flush manner; and eliminating the requirement of an air flow channel in the device, thus minimizing any adverse effects on the motion detecting element or sensor as well as providing built in partial hysteresis. The device may include additional transducers or sensors and is constructed such that the temperature sensor is neither exposed to the flow of air in a room or area n or in an airflow channel whereby a chimney effect may occur. The device has a passive alcove or cavity that acclimates to the ambient air temperature through the process ofdiffusion. The device can transmit and receive real time data, relative data and actual discrete data in addition to switching a nd controlling loads locally or remotely.

Patent CA-2334281-A1 (CA)
Inventor: DAVIS MICHAEL A
IPC: G06T7/60
Filed: 1999-05-27
Abstract: Prior to performing a centroid calculation on a waveform that is discretely sampled at a limited number of sample points, the last sample point (VN, AN) is eliminated if the magnitude of the amplitude at the first sample point (A1) is greater than the last sample point (AN), and the difference in magnitude between the first and last sample points (A1-AN) is greater than the difference in magnitude between the second to last sample point and the first sample point (AN-1-A1). The first sample point (V1, A1) is eliminated prior to the centroid calculation if the magnitude of the amplitude at the last sample point (AN) is greater than the first sample point (A1), and the difference in magnitude between the last and first sample points (AN-A1) is greater than the difference in magnitude between the second sample point and the last sample point (A2-AN). In a second embodiment of the invention, a first centroid calculation is performed using a set of samples in which one side of the waveform has the lowest amplitude value sample. Sample values on the side of the waveform initially having the lowest amplitude value are then eliminated until the opposing side of the waveform has the lowest amplitude value sample.  A second centroid calculation is then performed and the two centroid calculations are averaged together to arrive at an average centroid calculation. In a third embodiment of the invention, the amplitude components of the waveform sample values are normalized to the lowest amplitude value sample point and a first centroid calculation is performed on the normalized waveform. Next, the waveform is normalized to the lowest amplitude value sample point on the other side of the waveform and a second centroid calculation is performed. The two centroid calculations are then averaged to provide an averaged normalized centroid calculation.

Title: High gain, impedance matching low noise rf amplifier circuit
Inventor: CHO THOMAS BYUNGHAK
IPC: H03F1/56
Filed: 1999-07-15
Abstract: A low noise amplifier circuit provides high gain and an input impedance matching a source output impedance by combining two amplifiers having different operational characteristics in parallel. The amplifier circuit includes a first amplifier having an input impedance matching a source and a gain less than a system requirement and a second amplifier having a gain meeting the system requirement and an input impedance substantially higher than the input impedance for the first amplifier, the second amplifier being connected in parallel to the first amplifier. The first amplifier includes an input and an output and the second amplifier includes an input and an output, the input to the first amplifier and the input to the second amplifier being connected to the source. A summer is provided for combining an output signal from the first amplifier with an output of the second amplifier. The input impedance of the first amplifier and the input impedance of the second amplifier provide an effective circuit impedance equal to an output impedance of the source. The first and the second amplifier include low noise RF  amplifiers. Thus, the first and second amplifier provide an effective gain meeting the system requirement and an effective input impedance matching an output impedance of the source.
