Title: Ensemble directeur de bande pour le centrage de bandes transporteuses
Inventor: HOVSTO KENNETH
IPC: B65G47/16
Filed: 1997-05-28
Granted: 2006-03-14
Abstract: Cette invention se rapporte à un ensemble directeur de bandes servant au centrage de bandes transporteuses (5), qui comprend un mécanisme pourvu de rouleaux directeurs (1) et de rouleaux de guidage (9). En cas de défaut d'alignement latéral de la bande (5), le mouvement de la bande est transféré des rouleaux de guidage (9) aux rouleaux directeurs (1), ce qui a pour conséquence que les roleaux directeurs ramènent la bande à sa position neutre. Des rapports préférés entre différentes longueurs d'un bras de levier (6) pour le transfert du mouvement sont décrits. Un procédé pour charger une bande transporteuse consiste à déplacer la bande transporteuse (5) latéralement avant de la charger dans une position où le centre de gravité du matériau chargé (15) vient se situer sur la partie centrale (12) de la bande transporteuse, et à diriger, après l'opération de chargement, la bande transporteuse latéralement jusqu'à sa position neutre.

Filed: 1999-03-23
Granted: 2004-06-08
Abstract: A system of communicating between a master communication device and a plurality of slave communication devices is disclosed, whereby the master determines if any of the plurality of slave devices exist within a defined geographic area and, if so, sends a bit-by-bit command for the slaves to identify themselves; via a unique binary identification number. To avoid collision when the slaves respond, the slaves respond to the master's command within a predetermined time period of a time window providing the ID bit by bit. Responses are acknowledged by the master such that only one slave is able to respond with its complete full ID after a bit-by-bit command from the master.

Abstract: A warming system is provided for convectively warming a patient during a progressive medical procedure, such as cardiac surgery. The system includes one or more inflatable thermal blankets that are adjustably configurable to cover one or both of a patient's legs. Each thermal blanked includes an inflatable covering formed from an upper sheet and a base sheet attached at a plurality of locations.  The base sheet includes a plurality of apertures that direct an inflating medium from the inflatable covering toward the patient. A portion of each thermal blanket is initially furled us-ing a retaining device that prevents an inflating medium from inflating the furled portion. The non-furled portion of each thermal blanket is allowed to inflate and cover a patient. Prior to inflation, the furled portion of each thermal blanket defines a thermal blanket edge which demarcates an access area for a surgical procedure. When the re-taining strip is removed, the furled portion is unfurled by action of the inflating medium and self erects into a continuation of the previously inflated non-furled portion of the thermal blanket to cover the surgical access site. A surgical drape may be placed over the tops of the thermal blankets in order to properly position each blanket on the patient, to maintain the temperature controlled medium proximate to the patient, and to perform the usual barrier functions of a drape. In the operation, a heater/blower that includes a compressor and a heater supplies heated air, under pressure, to an inlet opening in the one or more inflatable thermal blankets. The heated, pressurized air is distributed throughout each inflatable blanket, and flows to the patient through the apertures in the blanket's base sheet.

Abstract: The invention provides methods and apparatus for decoding multiple program information, e.g., audio, video or image information, in a communication system. In an illustrative embodiment, a multiple program decoder includes a deinterleaver for deinterleaving information corresponding to a set of frames, using a specified deinterleaving length. A given one of the frames includes information from each of at least a subset of the programs, and the frames are encoded using an outer code, e.g., a CRC code, RS  code, BCH code or other type of linear block code, and an inner code, e.g., a convolutional code, turbo code or trellis coded modulation. The multiple program decoder includes an inner code decoder for decoding the inner code over one or more of the programs, and an outer code decoder for decoding the outer code for a selected one of the programs.  The deinterleaving length of the deinterleaver and operating rate of the inner code decoder can be configured such that the multiple program decoder provides substantially instantaneous tuning within a given cluster of programs, or within a set of clusters each including multiple programs. The programs may, but need not, include jointly-coded audio programs. The invention may be implemented in numerous applications, such as simultaneous multiple program listening and/or recording, simultaneous delivery of audio and data, etc.

Abstract: A logic structure adapted to receive pulsed active input signals produces a logical output with a very small inherent switching delay. In one particular embodiment of the present invention, a logic structure having PFET pullups (402, 406, and 410) and NFET pulldowns (404, 408, and 412), receives active low pulsed input signals (A, B, and C) and produces a logical high output signal (D) when all the input signals are at a low level. When at least one, but not all, of the input signals (A, B, and C) are low, the logic structure produces a logical low output signal (D), while sinking a DC current. When all of the input signals (404, 408, and 412) are at a high level, which is the default condition for this particular embodiment, the logic structure produces a logical low output signal (D), and no DC current paths are switched on.

Granted: 2004-04-20
Abstract: In this invention an optical gain element is used where a fraction of the optical output signal is passed through a periodic filter and fed back to the gain medium.  This configuration simply forms a multi-wavelength ring laser. The optical gain element provides the gain medium for the laser and the filter forces the laser to lase on the predetermined wavelengths. The periodic filter can simply be an asymmetric Mach-Zehnder Interferometer (MZI). It is known that asymmetric MZIs have an almost sinusoidal wavelength response where its period is a function of the length difference of the arms of the asymmetric MZI. Therefore, channel spacing may be controlled by changing the arms length difference in an Asymmetric MZI.
