Title: Frequency offset estimation using the phase rotation of channel estimates
Inventor: SCOTT KENNETH E
IPC: H03J7/02
Filed: 1993-11-17
Abstract: A receiver (10) for extracting complex values by reference to a local frequency reference determines the frequency offset between a local oscillator (16) and the carrier by employing a circuit (40) for determining a "phase rotation." When a record of the input signal is determined to have resulted from a predetermined reference sequence of complex values, the phase-rotation circuit (40) compares the phases of complex values extracted from this record with corresponding symbols of the reference sequence. By comparing this difference for one part of the sequence with that for another, circuitry (38, 50, 52, 53, 54) in the receiver infers the frequency offset between the transmitter reference and the receiver reference, and a complex multiplier (34) compensates for this offset by multiplying the successive complex-valued samples by a complex exponential whose frequency is the negative of the frequency offset.
Patent CA-2103435-A1 (CA)
Inventor: ZEMLAK WILLIAM A
IPC: B65H35/00
Filed: 1993-11-18
Abstract: ABSTRACT           A film dispenser having a housing with side and bottom walls, a film roll receptacle and a ledge located forwardly of the receptacle.   A heating wire is mounted transverse to the direction of movement of film from the film roll when mounted in the film roll receptacle.   A power supply is coupled to the output lines in series with said heating wire.   A switch is mounted on  the housing in series with the power supply and the heating wire and is operative upon closing to permit the passage of electrical current through the wire.   An elongated channel piece is pivotally mounted such that the pivot point is movable to a limited extent and, in response to pulling  up  film  from  film  roll,  the  channel  piece contacts  and  closes  the  switch and at  the  same  time pinches  the  film  against  the  housing. Upon  being released,  the channel piece causes  the opening of  the switch  and  removes  substantially  all  of  the  pinching effect.    A  guard mounted  to  the  housing  covers  the heating wire and, in response to pressure from said film moves upwardly so as to expose the heating wire and allow the film to contact the wire.  There is no need to mount the film roll on sockets in the film roll receptacle as in prior devices.

Title: Needle protection device
Inventor: KARLSSON JOERGEN
IPC: A61M25/06
Filed: 1992-04-13
Abstract: The present invention relates to a device for protecting a needle (6) in medical equipment. It has a rigid front part (10) connected to a flexible rear part (12). The front and rear parts surround the needle (6) circumferentially. A locking means (36) is accommodated in a chamber (24) provided in the front part (10). In a position of preparedness, the locking means allows the needle (6) to pass through a hole or a channel (14) in the front part (10) and, in an activated position, prevents the needle (6) from passing through. In the position  of preparedness, the parts (10, 12) are spaced from the tip of the needle (6). The novelty of the invention is that the locking means (36) is a resilient member which in the position of preparedness is maintained under tension, exerting a force substantially at right angles to the longitudinal direction of the needle (6), that at least the tip of the needle (6) in the position of preparedness is supported by the hole or the channel (14), the resilient member (36) being thus maintained under tension, and that the resilient member (36), after passing from the position of preparedness to the activated position when the needle (6) is moved rearwards relative to the front part (10), prevents the needle (6) from passing through the hole or the channel (14).

Patent CA-2111642-A1 (CA)
Inventor: CAVACIUTI ALESSANDRO
IPC: H04B10/291
Filed: 1993-12-16
Abstract: ABSTRACT            A laser device, if directly amplitude modulated, exhibits an unwanted  frequency modulation which  broadens  its  emission spectrum.  The unwanted frequency modulation is eliminated by carrying out a conversion of the modulated optical  signal wavelength,  using  a  semiconductor  optical  amplifier  as  a converter and another nonmodulated laser as a conversion signal generator.  Wavelength conversion takes place in the amplifier due to gain modulation induced by saturation.  An output signal at  the  conversion  signal  frequency,  taken  from  a  filter following the converter, presents an amplitude modulation equal and opposite to that of the modulated signal at input, but does not show frequency modulation.
