Patent CA-2155339-C (CA)
Title: A method for measuring temperature, molecular composition or molecular densities in gases
Inventor: BAATH LARS B
IPC: G01K7/00
Filed: 1994-02-03
Granted: 2005-12-20
Abstract: A measuring technique and method are provided to simultaneously determine the molecular density of several molecular species and the temperature within a closed process room in a melting or combustion process. In such processes in the industry, e.g. in metallurgic process industry, it is important to determine the temperature and the contents within the gas or flame without physically connect to or disturb the process. This has shown to raise large problems especially at high temperatures. The radio signal over a frequency band is measured on the outside of the process room through a window in the mantel covering as a function of frequency and registered on a computer as a radio spectrum. The system is calibrated by using a known signal transmitted through the process room. The spectral lines are identified by their frequency from a database. The temperature is determined from several lines of the same molecular specie and the molecular densities are determined from the intensities of the lines. The method is suitable to determine vibrational and rotational excitation of molecular species in the radio wavelength range of 500 m et 30 µm. The densities of molecular species and the temperature can be imaged in three dimensions inside the process room or exhaust channel if interferometers are used for simultaneous two dimensional imaging from several azimuth directions.

Title: Opposable-element chromatographic assay device
Inventor: CHANDLER HOWARD M
IPC: G01N30/02
Filed: 1994-03-31
Granted: 2007-01-23
Abstract: A chromatographic assay device for use with immunoassays allows rapid and convenient assays of analytes of biological interest, and permits extractions to be carried out in situ avoiding the use of separate extraction vessels. The device has a wide dynamic range and avoids interference from particulates or colored components. In one form, the device comprises: (1) a first opposable component (11) comprising a sample preparation zone adapted to receive a sample to be assayed; and (2) a second opposable component (12) comprising a chromatographic medium (14). The first and second opposable components can be brought into opposition so as to cause the sample preparation zone (13) to apply the sample to be tested to the chromatographic medium. Preferably, the analyte is detected with a visually detectable label. Other variations of the device vary the arrangement of components to provide optimal chromatography for a variety of analyzes, as well as to permit bidirectional chromatography; still other variations are suitable for competitive immunoassays. The devices can be incorporated in test kits, and assay methods, both sandwich and competitive, using the devices are also disclosed.

Title: Apparatus for scanning elevator call buttons
Inventor: MURPHY JAMES L
IPC: B66B1/46
Filed: 1997-02-04
Granted: 2005-08-16
Abstract: An apparatus for scanning and illuminating elevator car call button switches includes an individual switch and illumination circuit for each floor served by the car and a control circuit connected in a row/column matrix with the individual circuits for scanning for actuated switches and illuminating push buttons associated with registered calls. Each individual circuit has a switch module which responds to scanning signals from the control circuit by generating a switch actuated signal when the call button switch located therein is actuated. The control circuit generates illumination signals to each individual circuit for which a call has been registered to activate LED's and light the associated push button. The control circuit generates the scanning signal, reads the switch actuated signals and generates the illumination signals during separate timed cycles. A pulse stretcher module in the individual circuits responds to the illumination signals to maintain the LED's lighted for a significantly longer time than the duration of the timed cycles. The switch and illumination circuit and the control circuit cooperate to generate and respond to different magnitude switch actuated signals when an access control switch is utilized to lock out selected floors.

Granted: 2001-03-06
Abstract: In order to accomplish efficient communication of data between a base station and a plurality of mobile terminals, particular orthogonal codes are transmitted from the mobile stations to the base station as alert signals indicating the presence of data to be transmitted.  The base station checks whether particular orthogonal codes are contained in the alert signals, and when the particular orthogonal codes are detected in the alert signals, information representing the detected orthogonal codes and the schedules for transmitting the data from the mobile terminals to the base station are transmitted from the base station to the mobile terminals as an alert response to the alert signals.  When the information representing the orthogonal codes used for the alert signals are contained in the alert response transmitted from the base station to the mobile terminals, the data waiting to be transmitted is transmitted from the mobile terminals to the base station according the data transmission schedules in the alert response.

Granted: 2001-09-11
Abstract: Cette invention concerne un système de réglage automatique de vitesse, lequel permet de régler la vitesse d'une pompe à sang d'assistance cardiaque implantée selon un niveau optimal qui correspond aux divers besoins physiologiques du patient. Ce réglage se fait de manière périodique en incrémentant de manière répétitive la valeur de consigne de la vitesse de la pompe. Lorsqu'il détecte l'imminence d'un collapsus ventriculaire au niveau de la diastole, le système va décrémenter la valeur de consigne de la vitesse selon une marge de sécurité prédéterminée. Dans le cas où la diminution de la valeur de consigne se traduit par un débit sanguin insuffisant dans la pompe, un état d'alarme est déclenché. Le débit sanguin et l'imminence du collapsus ventriculaire sont calculés en temps réel comme des fonctions du courant du moteur de la pompe et de la valeur de consigne de la vitesse, uniquement.

Abstract: The characterization and detection of an identifying bit sequence is performed without digital demodulation or bit synchronization. A waveform containing a digital bit sequence is cross-correlated with waveforms corresponding to a set of known bit sequences. For each bit sequence, one of the inputs to a correlator is shifted through all possible values of correlation lag while the correlation match for each lag value is compared to the others so that a peak correlation between the two waveforms is determined. The peak correlation values for each of the known bit sequences are then compared to characterize how closely the received radio frequency signal corresponds to each of the known bit sequences. The bit sequence that most closely corresponds to the waveform of the received signal may then be identified. Applications include the identification of the N-AMPS DSAT and the GSM training sequence an a cellular radio scanning receiver.

Granted: 2001-07-24
Abstract: A communications system achieves high bit rates over an actual communications channel between M transmitter antennas of a first unit and N receiver antennas of a second unit, where M or N > 1, by creating virtual sub-channels from the actual communications channel. The multiple antenna system creates the virtual sub-channels from the actual communications channel by using propagationinformation characterizing the actual communications channel at the first and second units. For transmissions from the first unit to the second unit, the first unit sends a virtual transmitted signal over at least a subset of the virtual sub-channels using at least a portion of the propagation information. The second unit retrieves a corresponding virtual received signal from the same set of virtual sub-channels using at least another portion of said propagation information.

Abstract: A rotor (I) is of a substantially spherical shape with one complete half of the sphere (2) still remaining. The rotor (I) effectively takes the shape of the head of a "mushroom". The other half of the sphere has had its material removed or omitted forming the stem (3). The depth of the cut "D" and the length "L", the radius of the sphere, will determine the ratio of the respective weights of the complete half sphere (2) and the stem portion (3). Suitably the weight of the one half to the other half of the spherical body is between .75 and .85 and more preferably .8. When an external force is applied to the rotor (1) it rotates about a pair of orthogonal axes one of which is defined by the edge (6) of the spherical body between the two halves. >
