Patent CA-2093060-A1 (CA)
Inventor: STADE WAYNE R
IPC: H03F1/34
Filed: 1993-03-31
Abstract: An amplifier which combines the low quiescent current requirements of a Class B transistor amplifier with the minimal distortion qualities of a Class AB amplifier. In one disclosed embodiment the amplifier is utilized as a receiver amplifier and as a transmitter in a modular telephone adapter for coupling a telephone headset to a conventional modular telephone comprising a handset and a base unit. Signal expansion circuitry takes advantage of the dynamic emitter resistance of transistors in the amplifier's output stage through modulation of collector current in the output transistors and inverted phase summation of the resulting error signal with the input signal. DC bias circuitry supplies a current supply which is relatively insensitive to changes in power supply or device parameters. In one disclosed embodiment of the invention, two such amplifiers are utilized in a modular telephone headset adapter which allows a telephone headset and a telephone handset to be switchably connected to a telephone base unit.

Filed: 1993-05-28
Abstract: Apparatus and Method of Use For a Photosensitizer Enhanced Fluorescence Based Biopsy Needle Abstract A method and apparatus is disclosed for the instant intraoperative detection and biopsy of metastatic cancer using fluorescence spectroscopy.  A photosensitizing agent selectively retained by cancerous tissue is administered prior to surgery.  A fiberoptic probe integrated with a biopsy device illuminates the examined tissue and causes fluorescence which is  recorded by a  spectrograph and plotted as a spectral curve.  The intensity ratio (S1/S2) for the fluorescence from the photosensitizing agent (S1) and autofluorescence  (S2)  for the  examined tissue  is compared with the intensity ratio at the same wavelengths for primary tumor and normal tissue.  Tissue that displays an intensity ratio different from that of normal tissue can  immediately  be  analyzed  for  the  depth  of  tumor involvement and then excised for histological examination using the biopsy device.

Filed: 1991-12-13
Abstract: An audio signal processor (10, 12, 14) is disclosed for correcting harmonic and phase inaccuracies caused by the transduction, recording and playback of live audio signals. Operational amplifiers with fast slew rates and large bandwiths are used to implement a simple but effective circuit that can be reduced to a single chip.  Signal phase is continuously and automatically shifted as a logarithmic function of frequency to compensate for differences in propagation velocities, thereby reducing the spatial smear that is inherent in conventional loudspeaker designs. Harmonic frequencies present during a live performance are regenerated by the signal processor to restore realism to the reproduced audio signal.

Title: Computer controlled smart phacoemulsification method and apparatus
Inventor: COSTIN JOHN A
IPC: A61B19/00
Filed: 1992-01-02
Abstract: A method and apparatus for operating on the human eye detects changes in load, more specifically, mechanical impedance, of the transducer (300) and controls aspiration based on the load changes. A change from a lower load to a higher load indications that harder tissue is being encountered and accordingly causes aspiration amount to increase. Conversely, a change from a higher load to a lower load indicates that aspiration amount should be quickly decreased since the tissue which is being encountered is softer. One way to detect the impedance is by a sensor (1008), i.e., a piezoelectric element coupled to the operating needle detecting the movement thereof. <IMAGE>

Abstract: A microcell unit, in a cellular telephone system using digital signal processing BSs, is digitally connected to a macrocell, via a metallic link, such as a twisted pair. The microcell includes a plurality of radio channel units (RCU), to provide voice connectivity to mobile subscribers (MS), which are under control of a radio control complex (RCC) located in the macrocell. Several time slots of the macrocell TDM bus, through which the RCC exerts control of the RCUs, are remoted to the microcell thereby enabling control of the RCUs at the microcell location by the RCC of the macrocell. This remoting action is achieved, via a remote time division multiplex (TDM) circuit pack which enables the RCC to communicate with the RCUs as if they were located within the macrocell.

Patent CA-2116890-A1 (CA)
Title: Power supply shunt regulator
Inventor: DELEPAUT CHRISTOPHE
IPC: G05F1/613
Filed: 1994-03-03
Abstract: ABSTRACT OF THE DISCLOSURE:           A power supply shunt regulator (PSSR) is proposed which regulates the current flowing to a branch (FET, LD, CSR)  coupled in parallel to a power supply  (SA)  and an electrical load (EL).          The proposed regulator limits the discharge current from a parasitic capacitor (PSC) of the power supply when a shunt switch included in the branch is turned on. An active negative feedback loop (CLM, FET) therefore regulates the current through the branch by measuring the voltage drop (RI) over a current sensing resistor (CSR) included therein and by deriving a control signal (ACTRL,) for the shunt switch in such a way that this voltage drop strives in a critically damped way to a maximum voltage drop. This can be done in a simple way,  taking into account that the shunt switch is chosen to be a field effect transistor, thanks to the fact that an inductor (LD) is coupled to the source of the shunt switch ensuring stable operation.          This regulator is particularly well suited for use in spacecrafts where a number of power supply units, in each of which the power supply is constituted by a specific solar array, are used to supply power to the electrical load.
