Patent CA-2072021-C (CA)
Title: Vaginal speculum
Inventor: DICKIE ROBERT GERALD
IPC: A61B1/31
Filed: 1990-12-07
Granted: 1996-12-03
Abstract: A vaginal speculum is disclosed in which a ratcheted linear motion of a thumb pad is translated into a complicated linear, rotational and retractive motion of the speculum paddles to provide anatomically correct motions for dilation of the vagina and the cervix without complicated two-handed adjustments of the speculum. Cam follower pins follow the contours of a cam slot to translate the linear motion into the required complicated motions of the speculum paddles. The ratchet permits easy locking at any degree of opening while unlocking is accomplished simply by depressing the thumb pad to disengage the pawl from the ratchet bars. A fluid reservoir is built into the speculum to capture fluids discharged during examination.

Title: Subscriber loop tester for telephone switching systems
Inventor: HAMMOND JOHN A
IPC: H04M3/24
Filed: 1992-08-28
Granted: 1996-06-18
Abstract: A subscriber loop tester for testing local loops of telephone switching networks has a partitioned "U" interface and an internal bus architecture for converting various transceiver circuit output data formats to a common data format.  The "U" interface has a high impedance transformer meeting bandwidth and line matching requirements for different line codes and protocols for ISDN telecommunication systems. The transformer is selectively coupled to option cards each containing circuitry having AC and DC terminations matching specific line codes and protocols for ISDN telecommunications systems and other types of telecommunications systems. The option cards further contain programmable attenuators for producing a proper nominal signal level as a function of the specific line code and protocol and providing variable insertion loss.  A high speed bus is selectively coupled to the option cards for coupling the formatted transceiver circuit output data between the cards and a digital bus translator.  The digital bus translator selectively configures the high speed bus for the transceiver output data format of the selected option card and converts the formatted output data received on the high speed bus to a common data format.  Multiple source and destination audio paths in the subscriber loop tester are controlled by an audio switching matrix.

Title: Touch dimmer system
Inventor: WATSON DOUGLAS R
IPC: H05B39/08
Filed: 1993-11-08
Granted: 2004-09-14
Abstract: A key touch dimmer includes a switching device through which AC line current is passed to brighten a lamp in response to a control signal generated by a microprocessor. The microprocessor receives an input indicative of the zero crossing points of the AC line current and synchronizes this input with its own internal clock circuitry to generate a firing signal for the switching device at the correct phase angle in the next half cycle of the AC line current. The dimmer has memory capability whereby the lamp, when turned back on, will brighten to a preset level. This brightening is accomplished in a gradual manner. Likewise, a turned off lamp will fade to zero brightness, with the dimmer retaining the preset brightness level. The microprocessor shuts down quickly in the event of a power outage to preserve memory. An optional display includes a plurality of LEDs for indicating light level. Other options include providing the dimmer with several keys, each of which can be adjusted to a respective preset level.

Title: Medial region deployment of radially self-expanding stents
Inventor: HEYN LAWRENCE R
IPC: A61F2/06
Filed: 1993-02-23
Granted: 1996-04-16
Abstract: An apparatus (16) for deploying a radially self-expanding stent (18) includes proximal and distal sleeves (24, 30) respec-tively containing proximal and distal end regions (26, 38) of the stent in a reduced radius delivery configuration.  The sleeves can abut one another and thus contain the entire length of the stent, or may be used in combination with an outer catheter (158) sur-rounding the sleeves and containing the medial region of the stent.  In either event, once the stent and sleeves are positioned at the intended fixation site, the sleeves are moved axially with respect to one another to permit radial self-expansion of the stent initial-ly only over its medial region, while the sleeves continue to contain the axially outward regions of the stent.  Eventually, upon suf-ficient movement of the sleeves axially relative to one another, the stent becomes totally free of the sleeves, resulting in radial ex-pansion over the entire stent length. The axial relative movement of the sleeves can be controlled by two or more catheters (20, 44) mounted movably with respect to one another, one catheter integral with each of the sleeves.  Alternative arrangements for sepa-rating the sleeves include an externally threaded inner catheter (160), and a dilatation balloon (140) or membrane (206) expand-able to force the sleeves apart from one another.
