Title: Optical amplifier monitor using a blazed grating
Inventor: ASPELL JENNIFER
IPC: H01S5/14
Filed: 2001-01-25
Abstract: The traditional solution to monitoring the pump laser power uses the back facet of the pump laser to monitor its power. However, stability and aging issues of the back facet may make it difficult or even impossible to measure the pump power to a high degree of accuracy using this method. Pump lasers often use fiber Bragg gratings to stabilize their wavelength. However, if an in-line optical fiber blazed Bragg grating is used, then the pump power is coupled out of the grating to a detector and monitored. The method of the present invention minimizes components and provides a direct monitoring of fiber coupled power. Alternatively, light coupled out of a WDM is used in a similar manner to monitor the pump power.

Patent CA-2337497-A1 (CA)
Inventor: KOVACS MARK A
IPC: G01S7/487
Filed: 1999-07-19
Abstract: Multiple independent spectral measurements of light reflected from a target are produced concurrently by illuminating the target with a train of laser pulses wherein the train of pulses produces a line spectrum within the illuminating signal. A characteristic dimension of receiving aperture is established based on illuminating wavelength, a cross-sectional dimension of illuminated region of a target, and the range between a target and the receiving aperture or image plane. The characteristic dimension is the spacing of peaks in a speckle pattern of an image plane. The speckle results from destructive and constructive interference of coherent light waves reflected from the target. The use of multiple receiving telescopes having the characteristic dimension, allows for independent measurements concurrently by each of the receiving telescopes.       In addition, the generation of a train of pulses of illuminating radiation, or light, by laser is accomplished by mode-locked operation of the laser for synchronization of sinusoidal components at line frequencies of the pulse train spectrum, and wherein the spacing of the spectral lines is at least a decorrelation frequency. The number of spectral lines transmitted within each pulse equals the number of independent measurements attainable concurrently during reception of the reflected pulse train of light. Alternatively, in lieu of the line spectrum, the frequency may be swept linearly during the duration of a pulse such that the overall bandwidth of the frequency sweeping is equal to the bandwidth encompassed by the line spectrum of a pulse.

Title: Print-medium transport unit
Inventor: ARUGA KOTOYA
IPC: B65H35/00
Filed: 2001-04-17
Abstract: A print-medium transport unit including discharge rollers, a paper guide, and a lock member. The discharge rollers transport post-printed paper toward an outlet and can hold the leading end of the paper. The paper guide is placed upstream from the discharge rollers, and guides the leading end of the paper into the discharge rollers. The paper guide is rotatably supported so that the upstream side thereof opens a transport path of the paper, whereby when the leading end of the paper is held by the discharge rollers, the transport path allows the paper to be curved like a loop. The lock member locks the rotation of the paper guide when the leading end of the paper is guided into the paper guide. When the leading end of the paper reaches a predetermined position, the locking of the lock member is released.

Abstract: A postage meter (franking machine) uses a digital print head such as an ink jet or thermal transfer or dot-matrix print head, for which it is necessary to know the velocity of the mail piece passing by the print head. Two collimated monochromatic beams strike the mai l piece, one at an angle leading the mail piece velocity and the other at an angle lagging the mail piece velocity. The beams converge yielding a sensing region filled with a diffraction pattern. The mail piece, assumed to be rough at a scale that is appropriate for the velocity measurement, moves at some velocity. A detector detects light intensity (photon flux) at a small region  within the sensing region, and the intensity signal has a frequency that is proportional to the  mail piece velocity. The frequency is detected or measured, the instantaneous velocity is derived  therefrom, and the velocity is used to control the print head: In this way a two-dimensional print image (postage indicium) is faithfully printed on the mail piece with minimal distortion ev en in the event of non- constant velocity of the mail piece.

Title: Wearable, self-contained drug infusion device
Inventor: POWELL KENNETH G
IPC: A61M5/145
Filed: 2001-07-19
Abstract: A wearable, self-contained drug infusion device is disclosed that achieves the precise flow rate control needed for dose critical drugs. Valve or pump structures may be used with thermal flow sensors and closed-loop control circuits for providing the desired flow rate control. The device may have a two-part construction, where the electronic components are housed in a reusable portion and the fluid delivery components are housed in a separable disposable portion. This reduces the effective cost of the device to the user, assures sterility of the drug, and prevents fluid communication of the reusable portion by confining the fluid flow path to the disposable portion. The invention may include a wireless unit for controlling the operation of the drug infusion device. The wireless unit may communicate with the reusable portion using radio frequency (RF) methods, optical infrared (IR) methods, or other methods.

Abstract: A cooling system (11) for an off-highway vehicle (10) includes a heat exchanger (23) (e.g., an engine coolant or hydraulic oil heat exchanger) and a fan mechanism (27) for flowing air along a flow path through the heat exchanger (23 and 25).

The mechanism (27) includes a housing (29) and a fan in the housing. The fan (31) has forward curved blades (33), thereby to reduce system noise. A preferred fan (31) has a depth-to-diameter ratio not in excess of about 0.4 and, most preferably, not in excess of about 0.25. An alternate embodiment includes what might be termed a split-discharge arrangement wherein air blown by the fan (31) is discharged along two paths.

Title: System and method for improved registration performance
Inventor: DOBBERTIN MICHAEL T
IPC: B41J15/04
Filed: 2001-10-12
Abstract: An apparatus and method for advancing a receiver into registered relationship with a moving image-bearing member. A motor is provided that is responsive to motor drive pulses. A drive member engages the receiver, and a drive coupling connects the drive member and the motor. An encoder generates encoder pulses that correspond with movement of the image-bearing member. A pulse generator generates motor drive pulses in response to the encoder pulses to accelerate the receiver to a speed approximately equal to the speed of the image-bearing member speed. A timer determines an amount of delay time between detection of the receiver by an in-track sensor and the beginning of a subsequent movement of the motor. A delay mechanism delays the acceleration of the receiver to the image-bearing member speed by the amount of delay time.

IPC: B64D35/04
Filed: 2002-01-18
Abstract: A hybrid gear/sprocket-based transmission is provided for driving a pair of coaxial, counter-rotating propellers in aircraft and airboats. A drive shaft couplable to an engine crank shaft extends rearward into the transmission case, and a pair of coaxial hollow driven shafts extend rearward out of the transmission case, to which are attachable a pair of propellers. A gear train, containing an even number of gears, reverses the rotational direction of the engine; a sprocket train, containing two sprockets and a chain connecting them, retains the rotational direction of the engine. Improved stability characteristics are imparted by supporting the drive shaft at two points within the case and also by positioning the drive and the driven shafts in vertical alignment. The adaptability of the transmission to being coupled with an automobile engine confers improved noise, reliability, and fuel efficiency characteristics.
